Information on the pump’s operating agent

The operating agent used in the pump complies with the US standard FMVSS/116 DOT 4.

Operating agents which comply with this specification may be used instead of DOT 3 and may also be mixed with DOT 3.

? Store the operating agent only in its origi-nal container in a clean and dry place.Keep the container firmly sealed.

? Any contamination by dirt, water, crude oil products or other materials may result in damage to the pump.

? Operating agent which has been used must never be re-used.

? The operating agent will attack (dissolve)paint.

? When swallowing the operating agent

there is the danger of being poisoned.? Always keep the operating agent in a sea-led container and out of reach of children.

Disposal of waste oil

Under the amended law relating to waste disposal dated November 1, 1986 (valid in the Federal Republic of Ger-many) the disposal of used oil is subject to new provi-sions.According to legislation relating to waste disposal the so-called principle of causality is applied.Hence,anyone in possession of used oil is responsible for its proper disposal.

Used oils coming from vacuum pumps must not be mixed with other substances.

Used operating agents must be disposed of separately and in accordance with the regulations.

Operating agents from vacuum pumps that have been contaminated by other substances must be labelled, sto-red and disposed of as special waste with reference to the kind of contamination.Waste disposal key:+ 55256 x

In many countries proof of were the operating agent has finally been left is required by Law and often shipping of such contaminated waste requires permission by the authorities.Waste disposal information is available through:

1Description

TRIVAC-B-DOT pumps are oil-sealed rotary vane pumps having either a single stage or two stages.The number in the type designation indicates the pumping speed in m 3x h -1.

TRIVAC-B-DOT pumps can pump gases and vapours.They are used to evacuate brake systems and to degas hydraulics liquids.

The drive motor of the TRIVAC-B-DOT is directly flanged to the pump at the coupling housing.The pump and motor shafts are directly connected by a flexible cou-pling.The bearing points of the pump module are force lubricated sliding bearings.All controls as well as the oil-level glass and the nameplate are arranged on the front.All connections are to be found at the sides of the pump.The oil-level glass is provided with prisms for better observation of the oil level.

The pump module consists of assembly parts which are pin-fitted so as to allow easy disassembly and reassem-bly.The pump module can be easily removed without special tools.

TRIVAC-B-DOT pumps are equipped with special seals capable of resisting brake fluids.

1.1Function

The rotor (2/7), mounted eccentrically in the pump hou-sing (2/6), has two radially sliding vanes (2/5) which divi-de the pump chamber into several compartments.The volume of each compartment changes periodically with the rotation of the rotor.

As a result, gas is sucked in at the intake port (2/1).The gas passes through the dirt trap sieve (2/2), flows past the open anti-suckback valve (2/3) and then enters the pump chamber (2/6).In the pump chamber, the gas is passed on and compressed, after the inlet aperture is closed by the vane.

The operating agent injected into the pump chamber is used for sealing and lubricating.The slap noise in the pump which usually occurs when attaining the ultimate pressure is prevented by admitting a very small amount of air into the pump chamber.

The compressed gas in the pump chamber is ejected through the exhaust valve (2/10).The operating agent entrained in the gas is coarsely trapped in the internal demister (2/11);there the operating agent is also freed of mechanical impurities.The gas leaves the TRIVAC-B-DOT through the exhaust port.

During compression, a controlled amount of air - the so-called gas ballast - can be allowed to enter the pump chamber by opening the gas ballast valve.The gas bal-last stops condensation of vapours in the pump chamber up to the limit of water vapour tolerance as specified in the technical data for the pump.

Caution

GA/ET 01.208/3.02 - 06/97

The gas ballast valve is opened and closed by turning the gas ballast knob (7/5) on the front.

T o enable the TRIVAC-B-DOT to be used at intake pres-sures as high as 1,000 mbar, a special lubricating system was developed featuring force-lubrication of the sliding bearings.

A pump (3/6) for the operating agent pumps the opera-ting agent from the reservoir (3/5) into a pressure-lubri-cation system which supplies all bearing points (3/2).From there the operating agent enters the pump cham-ber area (2/6) of the vacuum pump.

The pump for the operating agent is fitted in the front end plate on the coupling side of the pump module.The suc-tion line for the operating agent is placed low, resulting in a large usable reservoir.

The operating agent is separated from the gas in the TRIVAC-B-DOT in two steps as described above.First,small droplets are coalesced into large drops in the inter-nal demister (2/11) fitted above the exhaust valve (2/10).These are then returned by deflection at the chamber wall of the volume for the operating agent back to the reservoir for the operating agent.This and the large usa-ble reservoir for the operating agent ensure long inter-vals between operating agent changes even at high inta-ke pressures.

Description

The vacuum is maintained by the TRIVAC-B-DOT by an integrated hydropneumatic anti-suckback valve (2/3)which is controlled via the pressure of the operating agent.

During operation of the TRIVAC-B-DOT the control piston (4/3) remains sealed against a spring (4/2) by the pressure of the operating agent.The valve disc (4/6) of the anti-suckback valve is held at the lower position by its own weight (valve open).When the pump stops (becau-se it has been switched off or because of a failure), the pressure of the operating agent drops and the spring (4/2) presses the control piston (4/3) up.Thus a connec-tion is provided between the case for the operating agent or the reservoir (4/1) for the operating agent and the piston (4/4) of the anti-suckback valve.Due to the pres-sure difference between the case of the operating agent and the intake port, the operating agent presses the piston (4/4) up and the valve plate (4/6) against the valve seat (4/5).The quantity of operating agent in the reser-voir (4/1) prevents the entry of air into the intake port (2/1) at the beginning of this process.

After the operating agent has flowed out from the reser-voir and when the valve plate rests on the valve seat, air follows in, which vents the pump chamber and forces the valve disc (4/6) against its seat.This effectively prevents backstreaming of any operating agent or its vapours.The anti-suckback valve (2/3) operates independently of the operating mode of the pump, i.e.also with gas ballast.

Operation

2.1Installation

TRIVAC-B-DOT pumps must only be ope-

rated in connection with brake fluid fil-

ling and degassing systems.

The TRIVAC-B-DOT pump can be set up on a flat, hori-zontal surface.Rubber feet under the coupling housing ensure that the pump can not slip.

If you wish firmly install the TRIVAC-B-DOT in place, ins-

ert bolts through bore holes in the rubber feet.

Max.tilt for the pump (without further

attachment) with possibly fitted standard

accessories is 10°from the vertical.

The rubber feet act as vibration absorbers.

They must therefore not be compressed by

screws.When installing the TRIVAC-B-DOT

pump, make sure that the connections and

controls are readily accessible.

The site chosen should allow adequate air

circulation to cool the TRIVAC-B-DOT (keep

front and rear unobstructed).The ambient

temperature should not exceed

+ 40 °C (104 °F) and not drop below

+ 12 °C (55 °F) (see Section 2.5.3).

The max.amount of heat given off approxi-

mately corresponds to the rated motor

power.2.2Connection to the

System

Before connecting the TRIVAC-B-DOT, remove the ship-ping seals from the connection flanges (7/2) and (7/3).

Retain the shipping seals in case you need

to store the pump in the future.

The pump is shipped with intake and exhaust flanges mounted for horizontal connection of the connecting lines.Y ou can easily convert the ports for vertical connection by removing the four capscrews, rotating the flanges as required, and reinstalling the capscrews. Connect the intake and exhaust lines with a centering ring and a clamping ring https://www.sodocs.net/doc/d03205681.html,e the centering ring with the dirt trap for the intake port.

Connect the intake and exhaust lines using anti-vibration bellows, without placing any strain on the pump.

The intake line must be clean.Deposits in the intake line may outgas and adversely affect the vacuum.The connecting flanges must be clean and undamaged. The maximum throughput of the pump is equivalent to the pumping speed of the pump (see Section 1.5).

2Operation

Caution Caution

Caution

GA/ET 01.208/3.02 - 06/97

Operation

The cross-section of the intake and exhaust lines should be at least the same size as the connection ports of the pump.If the inta-ke line is too narrow, it reduces the pumping speed.If the exhaust line is too narrow,overpressures may occur in the pump;this might damage the shaft seals and cause leaks.The maximum pressure in the case for the operating agent must not exceed 1.5bar (absolute).

When pumping vapours, it is advisable to install condensate traps on the intake and exhaust sides.

Install the exhaust line with a downward slope (lower than the pump) so as to pre-vent condensate from flowing back into the pump.If this is not possible, insert a con-densate trap.

The exhaust gases from the vacuum pump must be safely led away and subjected to post-treatment as required.In order to redu-ce the emission of operating agent vapours we recommend the installation of an addi-tional exhaust filter (Leybold accessory).Depending on the type of application or the kind of pumped media, the corresponding regulations and information sheets must be observed.

Never operate the pump with a sealed

exhaust line.

There is the danger of injury.The exhaust gases coming from the vacu-um pump must be lead away safely and subjected to suitable post treatment as required.

Before starting any work on the pump, the personnel must be informed about possible dangers first.All safety regulations must be observed.

2.3Electrical Connection

Before wiring the motor or altering the

wiring, ensure that mains supply for the pump is off and that it can not be applied inadvertently.

In order to prevent the pump from running up unexpectedly after a mains power failu-re, the pump must be integrated in the con-trol system in such a way that the pump can only be switched on again manually.This applies equally to emergency cut-out arran-gements.

Electrical connections must only be done by a qualified electrician as defined by VDE 0105 in accordance with the VDE 0100 gui-delines.

Observe all safety regulations.

TRIVAC-B-DOT pumps are available with a single-phase or a three-phase AC motor.

2.3.1Pump with Single-Phase AC Motor

Pumps equipped with a single-phase AC motor may be connected directly to the mains via the mains cord and the mains plug.

At 230 V use at least a 6 A slow-blow or a 10 A fast-blow fuse.

The direction of rotation need not be checked as it is fixed.

The motor is protected against overloading by a thermal overload switch with automatic resetting.

If the thermal overload protector shuts off

the pump, the motor will restart itself as soon as it cools.That's why the mains plug should be disconnected from the mains before starting with any work on the pump.

2.3.2Pump with Three-Phase AC Motor

TRIVAC-B-DOT pumps with a three-phase motor are supplied without accessories for electrical connection.They must be connected via the appropriate cable, and a suitable motor protection switch.Set the switch in accordance with the rating on the motor nameplate.Fig.8 shows the connection for pumps with 230/400 V ,50 Hz motors.Please also observe the motor wiring dia-gram in the junction box and the information given on the nameplate of the motor.

Warning Warning Caution

Warning

GA/ET 01.208/3.02 - 06/97Operation

After connecting the motor and after every

time you alter the wiring, check the direction

of rotation.To do so, briefly switch on the

motor and check whether a suitable cover

(e.g.a blank flange) is sucked in at the inta-

ke port.If not, interchange two phases of

the connection.

Observe the direction arrow on the coupling

housing.

2.4Start-up

TRIVAC-B-DOT pumps must only be ope-

rated in connection with brake fluid fil-

ling and degassing systems.

Do not select a degassing pressure of less

than 1 mbar, since at this pressure volatile

substances in the brake fluid may escape

and damage the elastomer seals of the

pump.

Each time before starting up check the level of the ope-rating agent.

For pumps with 3-phase motors, check the direction of rotation before starting the pump for the first time and after each change in the electrical connection (see Sec-tion 2.3.2).

On initial start-up, after prolonged idle periods or after having changed the operating agent, the specified ulti-mate pressure cannot be attained until the operating agent has been degassed.This can be done by running the pump for approx.30 min.with the intake line closed and the gas ballast valve (7/5) open.

Before starting the pump ensure that the

pump and the fitted accessories meet the

requirements of your application and that

safe operation can be guaranteed.

Avoid exposure of any part of the body to

the vacuum.There is the danger of injury.

Never operate the pump with an open inta-

ke port.Vacuum connections as well as oil-

fill and oil-drain openings must never be

opened during operation.

The safety regulations which apply to the

application in each case must be observed.

This applies to installation, operation and

during maintenance (service) as well as

waste disposal and transportation.

The standard pump is not suited for pum-

ping of hazardous gases or vapours.

Our technical sales department is available for further

advice in these matters.

2.4.1Areas of Application

The pump is not suitable for pumping of:

- ignitable and explosive gases or vapours,

- oxidants,

- pyrophorous gases.

The pumps are not suitable for pumping of

liquids or very dusty media.Suitable protec-

tive devices must be installed.

Our technical sales department is available for further

advice in these matters.

Operation

2.5Operation

TRIVAC-B-DOT pumps can pump condensable gases and vapours, provided that the gas ballast valve (7/15) is open and the pump has attained its operating tempera-ture.

2.5.1Pumping of Non-Condensable

Gases

If the process contains mainly permanent gases, the pump may be operated without gas ballast, provided that the saturation vapour pressure at operating temperature is not exceeded during compression.

If the composition of the gases to be pumped is not known and if condensation in the pump cannot be ruled out, run the pump with the gas ballast valve open in accordance with Section 2.5.2.

2.5.2Pumping of Condensable Gases and

Vapours

With the gas ballast valve open and at operating tempe-rature, TRIVAC-B-DOT pumps can pump pure water vapour up to the water vapour tolerance specified by the technical data.If the vapour pressure increases above the permissible level, the water vapour will condense in the oil of the pump.

When pumping vapours ensure that the gas ballast valve is open and that the pump has been warmed up for approximately 30 minutes with the intake line closed.

Vapour phases may only be pumped up to the permissible limit after the pump has attained its operating temperature.During pumping, vapours may dissolve in the oil.This changes the properties of the operating agent and thus there is a risk of corrosion in the pump.Therefore, don't switch off the TRIVAC-B-DOT immediately after completion of the process.Instead,allow the pump to continue operating with the gas ballast valve open and the intake line closed until the operating agent is free of condensed vapours.We strongly recom-mend operating the TRIVAC-B-DOT in this mode for about 30 minutes after completion of the process.

In cyclic operation, the TRIVAC-B-DOT should not be switched off during the intervals between the individual working phases (power consumption is minimal when the pump is operating at ultimate pressure), but should continue to run with gas ballast valve open and intake port closed (if possible via a valve).

Once all vapours have been pumped off from a process (e.g.during drying), the gas ballast valve can be closed to improve the attainable ultimate pressure.

2.5.3Operating Temperature

Proper operation of the TRIVAC-B-DOT is ensured in the ambient temperature range between 12 °C to 40 °C (55°F to 104 °F).

At operating temperature, the surface temperature of the TRIVAC-B-DOT may lie between 40 °C and over 80 °C (104 °F and 176 °F), depending on the load.

The surface temperature of the TRIVAC-B-DOT pumps may rise above 80 °C.

There is the danger of receiving burns.

2.6Switching Off/Shutdown

Under normal circumstances, all that you need do is to

electrically switch off the TRIVAC-B-DOT .

For longer standstill periods you must seal the pump so that no humidity can enter because brake fluid is hygroscopic.

No further measures will be required.

When pumping condensable media let the pump conti-nue to operate with the gas ballast valve open and the intake line closed before switching off (see Section 2.5.2).

When pumping aggressive or corrosive media, let the pump continue to operate even during long non-working intervals (e.g.overnight) with the intake line closed and the gas ballast valve open.This avoids corrosion during idle periods.

If the TRIVAC-B-DOT is to be shutdown for an extended period after pumping aggressive or corrosive media or if the pump has to be stored, proceed as follows:

After pumping of pumping harmful sub-stances, take adequate safety precautions.

Our technical sales department is available for further advice in this matter.

Maintenance

Drain the operating agent (see Section 3.2).

Add clean operating agent until the level is at the "min"

mark (see Section 3.2) and let the pump operate for

some time.

Then drain the operating agent and add clean operating agent until the level is at the "max" mark (see Section 3.2).

Seal the connection ports.Special conservation or anti-corrosion oils aren't necessary.

Please also take note of the information

given in Section 3.9 (Storing the Pump). 2.6.1Shut-Down through Monitoring

Components

When the pump has been switched off due

to overheating sensed by the motor coil pro-

tector, the pump must only be started

manually after the pump has cooled down

to the ambient temperature and after having

removed the cause first.

2.6.2Failure of the Control System or the

Mains Power

In order to prevent the pump from running

up unexpectedly after a mains power failu-

re, the pump must be integrated in the con-

trol system in such a way that the pump can

only be switched on again manually.This

applies equally to emergency cut-out arran-

gements.

3Maintenance

Disconnect the electrical connections befo-

re disassembling the pump.Make absolute-

ly sure that the pump cannot be acciden-

tally started.

If the pump has pumped harmful sub-

stances, contrary to what has been stated

in Section 2.4, ascertain the nature of

hazard and take adequate safety measu-

res.

Observe all safety regulations.

If you send a pump to LEYBOLD for repair please indi-

cate any harmful substances existing in or around the

pump.A form is available from LEYBOLD for this purpo-

se.

When disposing of used oil, you must

observe the applicable environmental regu-

lations!

Due to the design concept, TRIVAC-B-DOT pumps

require very little maintenance when operated under nor-

mal conditions.The work required is described in the

sections below.In addition to this, a maintenance plan is

provided in Section 3.10.

All work must be carried out by suitably trai-

ned personnel.Maintenance or repairs car-

ried out incorrectly will affect the life and

performance of the pump and may cause

problems when filing warranty claims.For

more information please contact the Ley-

bold Service.

If the TRIVAC-B-DOT is used in ambient air

which is much contaminated, make sure

that the air circulation and the gas ballast

valve are not adversely affected.

Maintenance

3.1Checking the Oil Level During operation of the TRIVAC-B-DOT the level of the operating agent must always remain between marks (9/2) and (9/3) on the level glass.The amount of opera-ting agent must be checked and topped up as required.

Fill in operating agent only after the pump

has been switched off.

3.2Oil Change

For proper operation of the pump, it is essential that the pump has an adequate supply of the correct and clean operating agent at all times.

The operating agent must be changed when it looks dirty or if it appears chemically or mechanically worn out. The operating agent should be changed after the first 100 operating hours and then at least every 2,000 to 3,000 operating hours or after one year.At high intake pressures and intake temperatures and/or when pum-ping contaminated gases, the operating agent will have to be changed much more frequently.

Further changes of the operating agent should be made before and after long-term storage of the pump.

If the operating agent becomes contaminated too quick-ly, install a dust filter and/or a filter for the operating agent (see Section 1.3).

Contact us for more information in this matter.

Only change the operating agent after the

pump has been switched off and while the

pump is still warm.

Required tool:Allen key 8 mm.

Remove the drain plug (9/4) for the operating agent and let the used operating agent drain into a suitable contai-ner.When the flow of operating agent slows down, screw the drain plug for the operating agent back in, briefly switch on the pump (max.10 s) and then switch it off again.Remove the drain plug for the operating agent once more and drain out the remaining operating agent. Screw the drain plug for the operating agent back in (check the flat gasket and reinstall a new one if neces-sary).

Remove the fill plug (9/1) for the operating agent and fill in fresh operating agent.

Screw the fill plug (9/1) for the operating agent back in.

If there is the danger that the operating

agent may present a hazard in any way

because of the media which have been

pumped, you must determine the kind of

hazard and ensure that all necessary safety

precautions are taken.

We can only guarantee that the pump ope-

3.3Cleaning the Dirt Trap

A wire-mesh sieve is located in the intake port of the pump to act as a dirt trap for coarse particles.It should be kept clean to avoid a reduction of the pumping speed. For this purpose, remove the dirt trap (2/2) from the inta-ke port and rinse it in a suitable vessel with solvent.Then thoroughly dry it with compressed air.If the dirt trap is defective, replace it with a new one.

The cleaning intervals depend on the appli-

cation.If the pump is exposed to large amo-

unts of abrasive materials, a dust filter

should be fitted into the intake line.

3.4Removing and Fitting

the Internal Demister

The internal demister is spring-mounted in a frame. When it is clogged, it rises periodically to reduce the pressure difference created.

The resultant noise at high intake pressures indicates that the internal demister is dirty.

Periodically clean or replace the internal demister;the maintenance interval depends on the https://www.sodocs.net/doc/d03205681.html,e a suitable solvent for cleaning.

Shutdown the pump and drain the operating agent (see Section 3.2).

Pull the handle upward.Remove the recessed screws.Don't remove the non-recessed screws;they hold the motor flange in place and should not be unscrewed.

Pull the case for the operating agent forward off the pump.

Remove the gasket and spacing discs/rings.

Take the internal demister out of its holder.Clean or exchange it and then fit it.

The sealing surfaces for the case of the operating agent and the coupling housing must be cleaned and dried. Reassemble in the reverse order.When doing so, make sure that the spacing rings have been fitted to the seals so that these are not compressed when tightening the screws.

Torque for the screws is 5 Nm.

3.8 Leybold Service

If a pump is returned to Leybold, indicate whether the pump free of substances damaging to health or whether it is contaminated.

If it is contaminated also indicate the nature of the hazard.For this you must use a form which has been prepared by us which we will provide upon request.A copy of this form is reproduced at the end of these Operating Instructions:"Declaration of Contamination of Vacuum Instruments and Components".

Please attach this form to the pump or enclose it with the pump.

This “Declaration of Contamination”is required to meet German Law and to protect our personnel.

Leybold must return any pumps without a "Declaration of Contamination" to the sender's address.

The pump must be packed in such a way,

that it will not be damaged during shipping and so that any contaminants are not relea-sed from the package.

3.8.1Waste Disposal of Used Pump

Materials

The corresponding environmental and safety regulations apply.This applies equally to used filters and filter ele-ments (filter for the operating agent, exhaust filter and dust filter).

-In the case of hazardous substances de-termine the kind of hazard first and obser-ve the applicable safety regulations.If the potential hazard still persists, the pump must be decontaminated before starting with any maintenance work.For professio-nal decontamination we recommend our Leybold service.

-Never exchange the operating agent or the filters while the pump is still warm.Let the pump cool down to uncritical temperatures first.Y ou must wear suitable protective clo-thing.

3.9Storing the Pump

Before putting a pump into operation once

more it should be stored in a dry place pre-ferably at room temperature (20 °C).Before the pump is shelved it must be properly dis-connected from the vacuum system, purged with dry nitrogen and the operating agent should be changed too.

Since the brake fluid is hygroscopic, the inlets and outlets of the pump must be sea-led with the shipping seals which are provi-ded upon delivery.

The gas ballast switch must be set to the "0"position and if the pump is to be shelved for a longer period of time it should be sealed in a PE bag containing some desiccant (sili-ca gel).

When a pump is put into operation after it has been shel-ved for over one year, standard maintenance should be run on the pump and the operating agent should also be exchanged (see Operating Instructions).We recommend that you contact the Leybold service.

旋片式真空泵是用来对密封容器抽除气体的基本设备。它可单独使用，也可用为增压泵、扩散泵、分子泵的前级泵、维持泵、钛泵的预抽泵用。可用于电真空容器制造、真空焊接、印刷、吸塑、制冷设备维修及仪器仪表设备配套和实验室等。广泛适用于食品、科研、医疗、电子、化工、医药、大专院校等部门。 一、操作须知 1、查看油位，以停泵时注油至油标中心为宜。过低对排气阀不能起封油作用，影响真空度。过高，啃了个会引起通大气启动时喷油。运转时，油位有所升高，属于正常现象。油采用规定牌号的清洁真空泵油，从注油孔加入。加油完毕后，应旋上螺塞。油宜经过滤，以免杂物进入，堵塞油孔。 2、泵可在通大气或任何真空度下一次起动，泵口如装接电磁阀，应与泵同时动作。 3、环境温度过高时，油的温度升高，粘度下降，饱和蒸汽压会增大，会引起极限真空有所下降，特别是用热偶计测得的全压强。如加强通风散热，或改善泵油性能，极限真空可得到改善。 4、检查泵的极限真空以压缩式水银真空计为准，如计经充分预抽效验，泵温达到稳定，泵口与计直接接通，运转30分钟内，将达到极限真空。总压强计测得之值与泵油和真空计、规管误差有关，有时误差甚至可能很大，只能作参考。 5、如相对湿度较高，或被抽气体含较多可凝性蒸汽，接通被抽容器后，宜打开气镇阀，运动20~40分钟后关闭气镇阀。停泵前，可开气镇阀空载运动30分钟，以延长泵油寿命。 二、结构说明 2xz型旋片式真空泵系双级高速直联结构旋片真空泵(以下简称泵)。它有偏心地装在泵身腔内的转子，及转子槽内的两旋片。转子带动旋片旋转时，旋片借离心力和旋片弹簧的弹力紧贴腔容积周期性地扩大而吸气，排气腔容积则周期性地缩小而压缩气体，借压缩气体压力和油推开排气阀排气，从而获得真空。 2xz型泵装有气镇阀。其作用是向排气腔充入一定量空气，以降低排气压力中的蒸汽分压强，当其低于泵温下的饱和蒸汽压时，即可随充入空气排出泵外，而避免凝结在泵油中。具有延长泵油使用时间和防止泵油混水时间。但气镇阀打开时，极限真空将有所下降，温升也有所提高。 2xz型泵具有体积小，重量轻，噪音低，起动方便等优点。此外，还有防止返油的措施和防止油封漏油污染场地的措施。 三、用途和使用范围 1.泵是用来对密封容器抽除气体而获得真空的基本设备。它可单独使用，亦可作为各类真空系统的前级泵和预抽泵。广泛应用于医疗、科研、化工、实验室、塑料、电子等行业，以及电真空器件制造、灯泡、保温瓶制造、真空焊接、仪器仪表及制冷设备、印刷包装机械配套等。 2.泵的工作环境：温度5℃90%时，应开气镇阀。90%，进气口压强小于10托的条件下允许长期连续运转，当被抽气体相对湿度大于90%时，应开气镇阀。 3.泵进气口连续敞通大气运转，不得超过三分钟。

莱宝真空泵油选择与使用指导 一、真空泵油的作用及性能要求 油封式旋转真空泵的泵油，必须符合相关要求。作为一种运动介质，泵油在真空泵中起着以下重要作用： 1，密封——防止大气进入排气阀，有相对运动零件间的间隙密封（转子与定子、旋片与转子槽等）。 2，润滑——相对运动件间的润滑，降低磨损。 3，冷却——油在泵内与油箱间循环，散热、冷却。 4，携裹——将磨损产生的尘粒或其他颗粒挟裹在油中，减小磨损伤害。 5，保护——形成保护油膜，避免水及化学蒸汽凝结物腐蚀泵内部件。 真空泵油的性能要求： 1，高温下饱和蒸汽压要低，易挥发成份要少。 2，最低水含量和吸水性。 3，要有一定粘度，且随温度变化小（粘度温升曲线平滑）。 4，润滑性能好，机械应力下具有良好的抗裂解性。 5，抗腐蚀、抗氧化、化学性能稳定。 对大部分应用，莱宝真空泵使用Leybonol品牌标准矿物质基油品，油牌号LVO 1XX，具有适宜的化学稳定性和热稳定性，耐水解，与密封材料的相容性很好。 针对一些特殊应用，标准油品的某些弱点表现为： 1，高温时的稳定性较差。 2，化学反应（酸、碱、卤素）的惰性较差。 3，遇到强氧化剂时（氧气）的惰性较差。 4，对非极性物质（蜡、油脂）的溶解性较差。 5，对极性物质（低聚物、树脂、分解产物、特别是结晶物）和聚合物的溶解性较差。 因此在特殊应用中，可以使用一些泵适用的特殊润滑品做工作液，或者在泵油中调入添加剂以增强某方面的性能表现。 但须注意，添加剂可能会使泵油的真空表现达不到期望值，如真空度差，甚至与抽排气体发生反应。因此使用如果未经审验的油品，可能造成换油频繁，真空性能降低，油反应产生沉淀，甚至损坏泵。 二、真空泵油的选择、使用、更换及储存 1，及时换油：经过一段时期的使用，泵油的性质会发生变化。比如机械应力作用下导致裂解，氧化变性，化学反应变性，水汽或可凝性气体融入导致水解乳化，化学物质的溶入导致性质变化，灰尘沉积导致粘度增大等。在这种情况下，泵油的状况已无法满足真空泵正常工作的需要，导致真空度变差、启动困难、泵温度升高、噪音增大等现象，此时需要及时更换新的泵油，以确保真空泵正常工作，延长泵的使用寿命。如果不及时更换，会导致泵的零件磨损增大、泵内零件腐蚀、寿命缩短、严重时甚至导致泵的损毁。 2，与泵相关的真空泵使用维护事项 2.1泵无故障运行的前提

一、2X型旋片式真空泵的产品用途及使用范围： １、2X型旋片式真空泵是用以抽除特定密封容器内的气体，使该容器获得一定真空的基本设备，由于现代科学技术的高度发展，真空泵的应用遍及各个科学领域和各种企业事业单位，可供冶金、化工、轻工、石油、医疗、制药、印染、电器、电真空、半导体、食品、原子能、纺织等科研机关、大专院校、工矿企业作科研和生产与教学之用。 ２、由于旋片式真空泵是用黑色金属制造，而且比较精密，整个泵的工作都是联系在一起的，所以旋片式真空泵不适用于抽除含氧过高的、有毒的、有爆炸性的浸蚀黑色金属的和对真空油起化学作用的各种气体，也不可做为压缩机和输送泵使用。如有气镇装置的泵，可抽除一定地的可凝汽体。， 3、旋片式真空泵可以用来直接获得真空度在10~3托以下的真空作业，以及配合其它真空作业之用。 4、旋片式真空泵一般在不低于5℃的室温及不高于90%的相对温度的环境内使用。二、2X型旋片式真空泵的结构及原理： 5、图1是旋片式真空泵泵原理图，转子3及7与高真空室外1及低真空室6相切，转子3及7沿箭头方向旋转，带动转子槽内滑动的转片旋转,由于弹簧9及离心力的作用, 转片外端紧贴高低真空室的内表面滑动,把转子与高低真空室所形成的月洼形空间从进气嘴2到排气阀门5和从过气管4到排气阀门10之间分隔开来,形成二或三个容积,并且周期性的大小变化,当在图示旋片式真空泵位置继续旋转时A及C容积逐渐增大,被抽容积气体没进气嘴进入泵内,同时B及D容积逐渐减少,压力升高,随后冲开排气阀门5及10,将气体排出真空室外,气体经过油面而排于大气之中,因为油是淹 住排气门的,故能防止气体返回真空室。当抽气压强较高时,高低真空室的阀门都排气,相当于单级泵,当真空度较高时,全部气体进入真空室,再由排气阀门10排出,此时二级串联即进入双级泵工作。 如被抽除的气体中含有较高的蒸汽气体时，在气体受到压缩而其蒸汽的分压强超过此蒸汽在泵内温度

真空泵分类 （一）淄博莱宝真空泵业有限公司 一、水环真空泵及压缩机 2SK系列两级水环真空泵和2SK-P1系列两级水环真空泵—大气喷射泵机组被用于抽取空气和其它无腐蚀性、不溶于水、不含有固体颗粒的 气体以便在密闭容器中获得较高真空。 它被广泛应用于食品、编织化工、医药和冶金工业及电子领域的真空蒸发、真空浓缩、真空回潮、真空浸渍、真空干燥及真空冶炼等。 具有真空度高、在高真空区抽速大及结构紧凑、工作可靠、维修方便等特点。 2SK系列适用于吸入压力低于-0.08MPa的工况条件。2SK-P1系列适用于吸入压力低于-0.096MPa的工况条件，在配用大气泵时，极限真空度可达－750mmHg。 工作真空范围为-0.03---0.08MPa。

SK系列水环式真空泵及压缩机是用来抽吸或压缩空气和其它无腐蚀性、不溶于水、不含固体颗粒的气体，以便在密闭容器中形成真空和压

力，吸入气体中允许混有少量液体。 SK系列水环式真空泵及压缩机被广泛应用于机械、石油化工、制药、食品、制糖工业及电子领域。由于在工作过程中，气体的压缩过程是等温的，所以在压缩和抽吸易爆炸气体时，不易发生危险，所以其应用更加广泛。 工作真空范围为-0.03---0.08MPa。

2BV系列真空泵适用于抽除气体和水蒸气，吸气压力可以达到33mbar绝压(97%真空度)。当真空泵在吸气压力低于80mbar的状态下长期工作时，应联接气蚀保护管，以对泵进行保护。如配大气喷射器，吸气压力可达10mbar，喷射器可直接安装在真空泵上。作为压缩机用时，其压力最大至0.26MPa(绝压) 性能特点 1、机泵同轴式直联设计，节省空间，易于安装。 2、采用机械密封作为标准配置,消除了泄露,维护简便。 3、运行平稳，噪音可低至62分贝。 4、统一的耐腐蚀设计，青铜叶轮提高了泵的耐腐蚀性，不锈钢材质更适用于更为苛刻的应用。 5、独特的柔性排气口设计，不会产生过压缩，确保了2BV在其性能范围内效率最佳

各种真空泵原理及使用说明

罗茨式真空机组的工作原理说明 JZJS罗茨水环真空机组是以罗茨泵为主泵，以水环泵为前级泵串联而成的。罗茨水环真空机组选用水环泵作为前级泵比其它真空泵更为有利，它克服了单台水环泵使用时极限压力差（机组的极限压力比水环泵有很大的提高），在一定压力下抽气速率低的缺点，同时保留了罗茨泵能迅速工作，有较大抽气速率的优点。尤其能够适应抽除大量的可凝性蒸汽，特别是当气镇油封机械真空泵排除可凝性蒸汽能力不够，或使用的溶剂能使泵油恶化而影响性能，或者是真空系统不允许油污染的时候更为明显。当配有防爆电机及电器时并遵守相应的安全规则下，还可抽除易燃易爆的气体。因此罗茨泵-水环泵机组广泛地用于化工行业中的真空蒸馏、真空蒸发、脱水结晶；食品行业中的冷冻干燥；医药工业的真空干燥；轻纺工业的涤纶切片；高空模拟试验等的抽真空系统中。 罗茨水环真空机组，大致有如下几种类型： （1）罗茨泵-水环泵：机组中水环泵的作用是造成罗茨泵所需的预备真空，一般情况，单级水环泵极限真空度不高，而目前我国生产的罗茨泵要求的预真空又较高，故实际上一般不用单级水环泵作为罗茨泵的前级泵，而用极限压力较低的双级水环泵作为前级泵使用，还可以降低机组的极限压力。 （2）一台罗茨泵与一台水环泵的极限压力是400P a，可满足一般的真空需求，但使用范围受到一定限制，若用两台罗茨泵串联再与水环泵组合，就能大大提高机组的极限压力（可达25P a）。故在这种类型里通常见到的是两台罗茨泵串联后再用双级泵作前级泵（图1）组成机组。如果需要更高的极限压力，可用三台罗茨泵与水环泵组合，它的极限压力可达1Pa。 （3）如果三级罗茨水环机组还不能满足极限压力时，可采用罗茨泵-水环泵并联机械真空泵；此机组主要用于需要处理大量水蒸汽，时间长且极限真空度要求非常高的抽真空系统，例如在真空干燥方面。

真空泵使用操作说明参考资料

液环式真空泵工作原理和操作说明 液环真空泵工作原理 如图：在泵体中装有适 量的水作为工作液。当叶 轮按图中指示的方向顺时 针旋转时，水被叶轮抛向 四周，由于离心力的作用， 水形成了一个决定于泵腔 形状的近似于等厚度的封 闭圆环。水环的上部分内 表面恰好与叶轮轮毂相 切，水环的下部内表面刚 好与叶片顶端接触（实际 上叶片在水环内有一定的 插入深度）。此时叶轮轮毂 与水环之间形成一个月牙 形空间，而这一空间又被 叶轮分成叶片数目相等的若干个小腔。如果以叶轮的上部0°为起点，那么叶轮在旋转前180°时小腔的容积由小变大，且与端面上的吸气口相通，此时气体被吸入，当吸气终了时小腔则与吸气口隔绝；当叶轮继续旋转时，小腔由大变小，使气体被压缩；当小腔与排气口相通时，气体便被排出泵外。当真空较低运行时，位于第二级真空泵排气汇集管里的逆止门打开，第一级的排气直接经逆止门排到分离器。当高真空运行时，逆止门关闭，第一级的排气进入第二级，再经第二级排气汇集口排入分离器。 综上所述，水环泵是靠泵腔容积的变化来实现吸气、压缩和排气的，因此它属于变容式真空泵。压缩气体基本上是等温的，即压缩气体过程温度变化很小。由于泵腔内没有金属磨擦表面，无须对泵内进行润滑，而且磨损很小。转动件和固定件之间的密封可直接由水封来完成。 水环泵也有其缺点：效率低，一般在30%左右，较好的可达50%。 真空度低，这不仅是因为受到结构上的限制，更重要的是受工作液饱和蒸气压的限制。用水作工作液，极限压强只能达到2000~4000Pa。 凝汽器液环式真空泵组的运行操作 真空泵的启动 1.检查真空泵系统各阀门处于启动前位置。各压力表、继电器、水位计考克打开，分离器和真空泵底部排水门关闭，补水（凝结水）总门打开，补水旁路关闭，板式换热器进出水门打开。

莱宝油封式真空泵油品使用说明

莱宝油封式真空泵油品使用说明

目录 1．真空泵油的作用及性能要求 2．莱宝真空泵油品牌及常用牌号 3．真空泵油的选择、使用、更换及储存4．油的状态判定 5．废油的处理

1．真空泵油的作用及性能要求 油封式旋转真空泵的泵油，必须符合相关要求。作为一种运行介质，泵油在真空泵中起着以下重要作用： l密封---防止大气进入排气阀，有相对运动零件间间隙密封（转子与定子、旋片与转子槽等）。 l润滑---相对运动件间的润滑。 l冷却---油在泵内与油箱间循环，散热、冷却。 l液体活塞---填充空隙。 真空泵油的性能要求： l高温下饱和蒸汽压要低，易挥发成分要少。 l最低的水含量和吸水性。 l要有一定粘度，且随温度变化小（粘度温升曲线平滑）。 l润滑性能好，机械应力下具有良好的抗裂解性。 l抗腐蚀、抗氧化、化学性能稳定。 对大部分应用，莱宝真空泵使用Oerlikon Leybold Vacuum品牌的标准油品, 油品牌号为N62, GS32, GS77, FM32, FM68等，具有适宜的化学稳定性和热稳定性，耐水解，与密封材料的相容性很好。 针对一些特殊应用,标准油品的某些弱点表现为： l高温时的稳定性较差。 l化学反应（酸、碱、卤素）的惰性较差。 l遇强氧化剂时（氧气）的惰性较差。 l对非极性物质（蜡、油脂）的溶解性较差。 l对极性物质（低聚物、树脂、分解产物、特别是结晶物）和聚合物的溶解性较差。 因此在特殊应用中，可以使用一些泵适用的特殊润滑品做工作液，或者在泵油中调入添加剂以增强某方面的性能表现。 但须注意，添加剂可能会使泵油的真空表现达不到期望值，如真空度变差，甚至与抽排气体发生反应。因此如果使用未经审验的油品，可能造成换油频繁，真空性能降低，油反应产生沉淀，甚至损坏泵。
