真空泵的使用方法
真空泵的使用方法真空泵是一种常见的实验室设备,用于产生和维持真空环境。
在各种科研和工业应用中,真空泵的使用方法至关重要。
本文将深入探讨真空泵的使用方法,包括基本原理、操作步骤和注意事项。
一、真空泵的基本原理真空泵的基本原理是通过排出容器内的气体分子,降低容器内的气体压力,从而产生真空。
根据工作原理的不同,真空泵可以分为机械泵、分子泵、扩散泵和陶瓷泵等。
其中,机械泵是最常用的真空泵类型,因其操作简单且价格相对较低而受到广泛应用。
二、真空泵的操作步骤以下是使用机械泵的典型操作步骤:1. 准备工作:确保真空泵和被抽空容器之间的连接是密封的,以防止气体泄漏。
同时检查泵的油位是否充足,必要时进行补充。
2. 启动真空泵:按下启动按钮或拧动启动开关,使真空泵开始运行。
在此过程中,真空泵会产生较高的噪音和振动,这是正常现象。
3. 执行抽气操作:将被抽空容器连接到真空泵的吸入口,并打开容器内的阀门,使气体进入真空泵。
4. 观察真空仪表:在抽气的过程中,观察真空仪表上的压力变化。
随着气体被排出,真空泵会逐渐降低容器内的压力。
5. 停止抽气:当所需真空达到时,关闭被抽空容器内的阀门,停止气体进入真空泵。
继续操作一段时间以确保所有气体都排出。
6. 关闭真空泵:当抽气过程完成后,关闭真空泵。
在关闭前,应考虑给泵提供适当的冷却时间,以防止过热。
7. 断开连接:当真空泵关闭后,断开与被抽空容器的连接。
注意,断开连接时应小心操作,避免气体泄漏或其他意外事故发生。
三、使用真空泵的注意事项在使用真空泵时,需要注意以下几点:1. 安全操作:在操作真空泵之前,请确保熟悉操作手册,并遵循正确的安全操作规程。
避免触摸运行中的泵或其它热的部件,以免造成烫伤。
2. 定期维护:定期检查真空泵的运行状况,并进行必要的维护。
保持泵的清洁,及时更换使用过的油和密封件,以确保其正常运行和延长使用寿命。
3. 防止过负荷运行:在使用真空泵时,应注意避免过负荷运行。

This is for the purpose of discovering any shortage or damage that may have occurred in transit. In event of such shortage or damage, a written report should be made immediately to the transportation company. An itemized shipping list will always be found in each shipment. Location of Pump The Beach-Russ type RP Rotary Piston Vacuum Pump is precision-built and deserves the best attention possible. It should be placed on a firm, level foundation in an accessible, clean, illuminated place. Allow ample space on all sides for servicing. For most efficient operation, the pump should be located as close as possible to the working apparatus. Storing Pump If unit is to be stored for an extended period before installation, fill entire cylinder with oil to prevent atmospheric corrosion. All water-jacketed areas must be checked for complete drainage (drain plugs are located at bottom of each jacketed area). Intake and outlet connections should be sealed. If stored outdoors, protect unit against weather. Foundation The foundation should be sufficiently heavy to afford permanent, rigid support for the pump. If the pump is not properly installed on a suitably prepared foundation or floor, the pulsation which is ordinarily negligible may be magnified and multiplied. It is therefore advisable to observe the following instructions carefully: Proper Placement When locating pumps on any floor of a building or anywhere except on ground level concrete foundations, care must be taken that the pump straddles a floor beam. Better still, it should be located to distribute its load over the floor beams or located near a wall or over a post or column. (See Figure N-737) Piping Connections For efficient operation and a tight piping system, use tubing or a good grade of new pipe, properly threaded and cleaned. Make up pipe joints with shellac or litharge & glycerin mixed to the consistency of heavy cream. No red or white lead should be used on pipe joints. CAUTION : 1) Remove shipping plugs from suction and discharge connections of pump. 2) Clean pipe thoroughly before connecting to the pump. Chips, burrs, scale or other foreign matter should never be left in the suction pipe line. Any foreign objects inside the pump can jam or score the parts, resulting in serious damage. Special caution should be used in this regard when welded or brazed pipe is used.Beach-Russ Company, 544 Union Avenue, Brooklyn, NY 11211. Ph: 718-388-4090; Fax: 718-963-2826 Email: sales@ | beachrus@Flushing & Testing ValveInstall a valve close to the pump suction. The valve should be vacuum tight and of a type that produces practically no line friction (gate, ball or diaphragm valve) Suction Line Run suction piping in as short and direct a line as possible. Use long radius elbows to reduce pipe friction. Install unions close to all pump connections, so that the pump may be easily disconnected from system if necessary. Install either a manual or solenoid-operated vacuum break valve on the suction line to the pump. This valve will prevent the possibility of the pump rotating backward, or filling with oil on shutdown. Never reduce pump suction piping unless pipe friction, pressure and flow rate calculations prove that pipe sizes can be reduced. When ultimate low pressure are desired, use full pipe size. Exhaust Line Discharge piping, if possible, should be piped to outside of the building, so that the oil vapors can be exhausted to the atmosphere. Models 135 to 1000 RP require outside exhausting. Smaller pumps operating at high vacuum, where slight traces of oil vapors are not objectionable, often need not be piped to the outside. Where exhaust vapors are objectionable, Beach-Russ mist filters can be used to eliminate these vapors. In making up discharge pipe lines, piping on top of pump should extend vertically for at least 4 to 6 ft. Where large quantities of water vapor are exhausted, a trap or exhaust line must be installed to prevent condensate backflow into the pump. Cooling Water Line Models 15, 30 and 50 RP pumps are air-cooled. Water jackets can be supplied on these pumps in special cases. All larger sizes are water-cooled. The pump, water or air cooled should operate so that the non jacketed areas of cylinder are warm to hand. There are cases where a pump operating at vacuums of approximately 28” will normally operating higher temperatures. Connect water supply to cooling water inlet which is tagged. Install a valve on inlet, not outlet side so that flow of water may be regulated. Install unions close to pump on inlet and outlet connections. Run discharge pipe from water outlet on pump to an open drain at a convenient location near the pump so that the temperature of cooling water can be easily determined at all times. Inlet water temperature could be anywhere from 600 to 800 F. outlet temperature of cooling water for normal operation should be approximately Delta T 200 F. rise. CAUTION : Valves or fittings which will cause back pressure in water jackets are not permitted in the water discharge line. Unavoidable back pressure above 30 Lbs, should be checked with Beach-Russ Company.Beach-Russ Company, 544 Union Avenue, Brooklyn, NY 11211. Ph: 718-388-4090; Fax: 718-963-2826 Email: sales@ | beachrus@Electric Solenoid Valve Solenoid should be connected in parallel with motor terminals, never in series. The solenoid will operate properly on voltage 10% higher or lower than rated voltage. With this type of solenoid, the valve will open when the solenoid is energized and will close when it is de-energized. Before running the pump, remove one of the plug fittings from oil line. Energize solenoid coil, without starting pump. Check oil flow at the open fitting. Testing & Servicing Solenoids 1. To check the electrical system, energize the solenoid. A metallic “Click” is heard if the solenoid is operating. Absence of “Click” indicates loss of power. Look for a loose connection, open circuit or burnt coil. 2. To check for a burnt coil, turn off power, remove cap nut, lift off the housing cap. Remove spring washer or retaining clip, upper flux plate and insulating washer. Replace coil if it is burnt out. 3. To examine the internal parts, shut off the power and line pressure. Lift off the top assembly by removing the four top screws or unscrew top assembly. Depending on type of solenoid , inspect valve seats, plunger or diaphragm for rupture. Also check that the two bleed holes are not clogged. When ordering solenoids or solenoid parts be sure to give solenoid model number and voltage of the coil. Belt Adjustment Ideal tension is the lowest without belt slippage or flapping, required for operation under peak load conditions, since new v-belts have a tendency to stretch during initial run-in period. It is advisable to check tension after the first 36 hours of operation. Either too low or too high tension will adversely affect the life and operation of the belts. CLASSES OF PUMPS Class “D” PumpThe class “D” type RP pump is used in the majority of normal applications. Units are supplied with a combination automatic lubricating system and oil separator. The separator collects the oil, carried over by the exhaust air, through a series of baffles and re-circulates it back to the pump. A vapor purge valve, on the back head of the pump, prevents vaporized moisture from condensing. A gauge glass indicates the oil level and a drain cock is provided to facilitate the removal of old oil. (See Drawing )Class “WS” Pump Class “WS” type RP pumps are primarily designed to handle large quantities of condensable vapors and gas loads from wet system. These pumps are provided with special large oil separators. The oil distributing pan drips the oil and water to the bottom of the separator. The water on the bottom of the separator will eventually flow through the water overflow pipe (standard equipment) or through an automatic water discharge trap (optional equipment). (See Drawing)Beach-Russ Company, 544 Union Avenue, Brooklyn, NY 11211. Ph: 718-388-4090; Fax: 718-963-2826 Email: sales@ | beachrus@Class “WSV” Pump Oil or water and oil emulsion is immediately discharge into the oil separator. Water can not accumulate on the valve while pump is in operation and while air is moving through the pump. Rapid vacuum recovery can be obtained to immediate sealing of the valve with oil, making it possible for high vacuum to be rapidly obtained. (See Drawing) Class “VP” Pump Class “VP” type RP pumps are specially designed to handle condensable and non-condensable vapors which are harmful to the lubricating oil. The class “VP” pumps are designed so that the gases pumped through the unit have only minimum contact with the lubricating oil. The vapor purge valve keeps the condensable vapors in a gaseous form, which in turn acts as a vehicle in removing the non-condensable vapors. Auxiliary equipment, such as automatic water traps, heaters and oil coolers can be supplied to meet special conditions.OPERATION OF PUMP Before Starting a New Pump 1. Put oil into pump, oil fill until correct level is indicated on gauge. 2. Check motor wiring for correct pump rotation. 3. Open oil line valve. If electric solenoid is used this step is automatic. Check for proper voltage connection. 4. Before turning power on, turn pump pulley by hand in direction indicated by arrow on pump (counter clockwise-facing pulley side). This will indicate if foreign matter is in the pump, thereby preventing serious damage to either pump or motor. 5. Turn on cooling water valve (if no solenoid is on water line). Model 135 and larger are water-cooled. Smaller models are sometimes water-cooled in special cases. Start pump with electric switch on motor circuit. Note : It is important before starting a pump that has been in operation to check the amount and condition of the oil.Note : On models 375 through 1000 – when starting pump it may be necessary first to open valve “A” (See drawing ) until pump gets up to speed and then close valve “A” tightly.CAUTION : When pumps are not in use for a long time (especially Model 135 and larger) the following instructions should be followed before the pumps are turned over by power: Pour a gallon or two of regular lubricating oil into the pump. We also recommend removing oil line plugs and pouring oil down into pump bearings. Turn pump over as described above. This will lubricate any dry spots that may be in the pump and will prevent any scoring that might occur if the pump is started without taking these simple precautions.Beach-Russ Company, 544 Union Avenue, Brooklyn, NY 11211. Ph: 718-388-4090; Fax: 718-963-2826 Email: sales@ | beachrus@Stopping of Pump Caution : Before pump is shut down, close oil line valve. This procedure is not necessary if solenoids are used. If possible open pump to atmosphere for one minute before shutting down. If pump will be out of service for a long time, fill entire pump cylinder with oil to prevent atmospheric corrosion. Be sure to remove this oil before starting the pump again.If pumps are to be left idle in freezing weather, all pump water jackets must be drained of all water content. Drain plugs should be installed at lowest points of all jacketed areas. If units are shipped back to Beach-Russ for repair, drain all jackets. Setting the Purge Valve Properly (Gas Ballast) The “Vapor Purge” valve is shipped with the vacuum pump. The correct valve setting is different for each installation and operation, depending on the amount of moisture entering the pumps. The valve should be opened to a point where enough air is bled into the pump to prevent the heaviest vapor load from condensing. Open valve until no emulsification or change of color of the oil can be seen in the oil level gauge on the reservoir. The Beach-Russ “Vapor Purge” Pump, operated with the “Vapor Purge” valve completely closed has the operational features of the standard Type “D” pump. If extremely high vacuum is desired, we suggest that after the bulk of the vapor load has been handled, the “Vapor Purge” valve be completely closed. If this is done we recommend periodically purifying the oil supply according to instruction given below. Purifying the Oil Supply At the end of the operating cycle, if the vapors have emulsified the oil, blank off the pump and completely open the “Vapor Purge” valve. Run for approximately 30 minutes to purify the oil supply. Repeat, if necessary. MAINTENANCE CHANGING OIL : Drain and replace oil when it becomes contaminated or emulsified. Open drain on separator and/or valve box and drain oil. Then remove oil strainer located in main oil line where it leaves the oil reservoir. This strainer should be removed, inspected and cleaned when oil is changed. The strainer can be removed by removing the flat square cover plate identified by the words “OIL STRAINER CLEAN OFTEN” cast on its surface. After checking strainer, close drain valves and fill reservoir through oil-fill plug to level indicated in gauge glass.Beach-Russ Vacuum pumps can run with any brand type Mineral oil having following specifications.

Ph: 718-388-4090; Fax: 718-963-2826 Email: sales@ | beachrus@On many operations, particularly in chemical and food plant work, vapors may enter the pump and gum up, clog or coat the interior surfaces. This may cause the pump to bind or clog the oil lines. To properly clean the pump, the oil must be removed from the reservoir and a mixture of a solvent such as kerosene, benzene, acetone or alcohol with 25% oil poured into the pump suction while the pump is turned over by hand. After the pump appears to turn easily and the solvent is up to oil level in the reservoir, the power should be turned on and the pump run 2 or 3 minutes. After this, the solvent should be removed and flushed out with oil and a fresh charge of oil put into the pump.

Mark position of taper bushing on pump shaft (when reassembling, place taper bushing on set scribe line for proper alignment) 3. Remove taper bushing cap screws and insert into bushing tapped holes. 4. Screw cap screws in evenly until pulley (Sheave) is loosened from taper bushing and remove sheave and bushing. 5. Before removing rotary seal be sure the oil line to seal is off. 6. Remove two 3/8” Allen set screws (15A) on inner race of bearing (15) 7. Remove gland screws and using the two tapped holes on gland, evenly remove gland (4C) with bearing from front head, remove gasket (4C(G)). Use shims under jack screws for further jacking off gland, If necessary. 8. Remove gland, inspect face if damaged or uneven wear, lap gland surface. This surface and the outer face of the rotary seal prevents oil leakage. 9. To remove rotary seal (4B) from rotary seal housing (This is a double ended seal) use two button hook type wires and hook in the rear end of rotary seal, pull evenly on both hooks to remove seal unit. 10. Inspect rotary seal faces, if damaged replace with new seal. 11. When replacing seal make sure shaft is clean and generously lubricate all parts of seal and shaft with pump lubricating oil before placing new seal assembly on shaft. 12. Before securing the gland to front head (4) press gland against the rotary seal face two or three times to make sure the seal is not hung up on pump shaft. The rotary seal will push gland out from head upon releasing gland. If no further inspection of pump parts is necessary replace parts as taken off.If inside of pump inspection is necessary do not replace parts and continue as follows:Inspection of pump back head (5) & back shaft (2)1. Remove oil line piping on back head (5).2. Remove screws on back head cap (5B) remove cap and gasket (5B(G))3. Remove two 1-1/4” pipe plugs (5P) and two hidden ½” Allen socket head screws (5N) under pipe plugs.4. Remove back head screws and insert four screws in tapped holes on back head and jack head off cylinder (1) by evenly tightening jack screws. Use shims under screws for further jacking head off cylinder. Do not remove dowel pins.5. Inspect head bushing (5A) clean as needed (use solvent) inspect oil groove and oil hole leading into bushing . inspect two secondary oil line holes in back head, blow out and clean. There are three lubrication holes in the back head (same construction on front head) Note : If back head is frozen on shaft, apply heat to section of head that contains bushing. Use of acetylene torch will help to remove frozen head. If bushing (5A) I.D. measures more than .007” larger than pump shaft diameter at any point in bushing , replace the head bushing. Note : At this point an inspection of the internal parts can be made.Inspection of pump internals1. Place a wooden V-block under back shaft.2. Replace pump pulley and bushing on front shaft.3. Push rotor against cylinder wall by exerting pressure on exposed rotor shaft. Rotate rotorby turning pump pulley and check for foreign matter in cylinder or gate.4. Check for internal wear by inserting a feeler gauge between one rocker seal (3A) andcylinder wall, rotate rotor 3600, check for clearance. If greater than .030” at any point , anew seal (3A) or a pair of rocker seals will be necessary. (A minimum of .005” is desired for proper clearance at the tightest point of 3600 check)Under cut-off plate (2D) check spring (2J) by removing screws (2L). replace spring, if necessary. The screws (2L) have a shoulder that should seat against rotor snugly when screw is tightened (use locktite on screws) These special screws give the cut-off plate its automatic clearance from the rotor. The rotor plate can be moved and spring action felt.Note : Do not remove Rotor shafts from rotor.Removal of pump internal parts1. Removing rocker seals (3A) place gate (3) in vertical position using three corner file onside of rocker seal, slide out top rocker seal. Turn rotor 1800 slowly and remove secondrocker seal from top.2. Place gate in horizontal position. Slide length of wood more than half way throughcylinder to support rotor.3. Carefully slide rotor from cylinder. When rotor is half way out re-adjust support underrotor body and remove rotor.4. Slide gate out of rotor, this will allow the keys and springs (2E) and 2F) to be removedfrom their slots.5. Check parts for excessive wear, clean with solvent and wire brush. (Score marks incylinder wall or on head faces, etc. need only be touched up with emery cloth to removeany projections.)6. Badly worn gate should be replaced.7. Check front head (4) it may not be necessary to remove head from cylinder. Clean andcheck as instructed on back head.8. Do not try to machine cylinder bore. This is a patented elliptical design. Contact factory ifthere is any anxiety about condition of cylinder.Note : After removing pulley and gland smooth off any set screw marks or ridges to help preventbinding on removal of rotor from head.Installing Internal parts1. Place key, spring (2E) and (2F) into rotor key and spring groove, hold parts with screwdriver and slide gate into rotor slot trapping key and spring in groove.2. When gate is part way in slot place other rotor key and spring in second key and springgroove, hold as before and slide gate through rotor.3. Lubricate front shaft of rotor, place gate and rotor in horizontal position with wooden blockin cylinder using sling around rotor. Place rotor into cylinder using front head for line upand bearing point.4. After placing rotor in head, put once rocker seal in gate. Set gate in vertical position andslide in second rocker seal at top of gate. If new rocker seals are needed, check forclearances through 3600. if rocker seal does not fit, draw file length of strip a fewthousandths and emery clean. In many cases an old and new seal can be used withoutfiling rocker seal.5. Before replacing back head (5) clean surfaces on cylinder face head and wipe dry. Mix asmall portion of litharge and glycerin to the consistency of mustard, apply an even coat @.003” thick on surface of cylinder face, press and smooth on a .005” paper gasket (5(G))on cylinder holding gasket in place with four studs in cylinder tapped holes. (this gasketused only on back head joint) apply mixture on gasket surface and install head usingdowel pins for proper alignment. Tighten bolts evenly all around until bolts are snugly inplace.Note : After ½ hour, turn pulley one revolution to insure the litharge inside the pump does not setand bind pump rotor. Do not run pump until the litharge joint hardens (@ 2 to 3 hours)Inspection of exhaust valve1. Drain oil from valve box (6) through valve (6D)2. Remove bolts, valve box and gasket (6(G))3. Remove Nut and spring holder (7B)4. Check valve discs (7D) and spring (7C) check discs for pit holes or uneven wear, checkspring for compression and cracking.5. Check seats of valve (7) for cracks, chipped surfaces of excessive wear. A clean, smoothraised surface for each disc is necessary. Lap or replace, check inside of valve andremove if necessary for further cleaning.6. Check studs (7G) for worn areas, the section where valve disc holes may hang up on ifstud badly worn. If holes in disc are worn so that the disc holes do not center the disc onthe raised surface of valve – replace discs.7. Before assembling and replacing valve body use new gasket (7(G)) and bolt valve tocylinder tightly.Inspection of oil lubricating system1. Drain separator (8) through valve (8D) remove cap (10A) and gasket (10A(G))2. Pull out oil screen sleeve (10B) and screen (10C) remove spring (10D)3. Clean screen (10C) with solvent and replace if collapsed or torn.4. Replace parts as removed using new gasket.5. Remove solenoid cap, cover and coil from oil solenoid. Screw off core and plunger andcheck solenoid seat and disc. Install spring in core housing as removed.6. Clean seat and disc of foreign matter and replace parts as removed.Note : When solenoid valve is functioning properly an internal click can be heard when solenoid isenergized and top of solenoid becomes magnetized. (same information applies to other solenoidvalves. On solenoid valve seat and disc can be checked by removing four cap screws on bonnet.1. Oil cooler (105) is water cooled. Water through copper tubing and oil around tube walls.This cooler has two zinc plugs that should be checked and replaced when used up.These plugs help prevent corrosion in copper tubing wall due to cooling waters.Note : Solenoids on oil cooler can also be checked for proper functioning by feeling pipe linesleading to and from oil cooler. If there is no difference in temperature a flow problem exists.Cleaning separatorThe separator rarely has to be taken apart. However when changing oil, if there is an indicationthat there is a large amount of slug build up in separator, remove inspection plug (8E) to checkand flush separator , if necessary.Suction screen1. Suction screen (1D) should be checked yearly unless indication in the vacuum processshows that there is a possibility of build up of matter on screen. To clean, drop bottomflange (1C) and inspect screen.2. Check screen for corrosion and clean or replace.TYPE RP PARTS LIST Item Part Name1* Cylinder1A Manifold1A(G)* Manifold Gasket1B Suction Flange1B(G)* Suction Flange Gasket1C Manifold Screen Cover1C(G)* Manifold Screen Cover Gasket 1D* Suction Screen1E Water Jacket Plate1E(G)* Water Jacket Plate Gasket2 Rotor Assembly2C Cut-off Plate – Front2D Cut-off Plate – Back2E Rotor Key2F Rotor Key Spring2J Cut-off Plate Spring2L Cut-off Plate Screw3 Gate3A* Rocker Seal4 Front Head4A Front Head Bushing4B* Rotary Seal Assembly4C Gland4C(G)* Gland Gasket4D* !

博山2BV水环真空泵说明书
一、2BV型水环式真空泵的概述:2BV型水环式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)。
当用变压器油作为工作液时(称为油环真空泵),吸气压力可达到6.7mbar绝压(99.3%真空度),可以完全取代往复式真空泵。
当液环真空泵在吸气压力接近极限真空下长期工作时,应联接气蚀保护管,以对泵进行保护并消除气蚀声。
作为压缩机使用时,其压力最大至0.26MPa(绝压)。
作为压缩机使用时,随着排气压力的升高会造成2BV泵功率的加大,订货时应注明排气压力以选择适当的电机功率。
2BV型水环式真空泵作为新一代节能型产品,其以出色的性能及众多优点将全面取代同性能的SK、2SK系列水环真空泵及W、WY、WL系列往复真空泵。
2BV2-Ex、2BV6系列水环式真空泵/压缩机主要用于抽除爆炸性气体,及在各类易燃、易爆环境中工作,其性能参数与2BV2、2BV5系列相应型号相同。
2BV系列不锈钢真空泵可使用在各种耐腐蚀要求较高的场合及洁净度要求较高的场合。
根据工况2BV系列不锈钢真空泵的全部过流部件:泵体、泵盖、圆盘、叶轮材质可选用SUS304(0Cr18Ni9)、SUS316(0Cr17Ni12Mo2)、SUS316L(00Cr17Ni14Mo2)等各类不锈钢材质,泵轴材质:2Cr13或0Cr18Ni12Mo2Ti2BV型水环式真空泵机械密封采用进口产品,密封件可采用氟橡胶或聚四氟乙烯.二、2BV水环式真空泵的工作原理:2BV水环式真空泵如图(1)所示叶轮3偏心地安装在泵体之内,起动时向泵内注入一定高度的水,因此当叶轮3旋转时,水受离心力的作用而在泵体内壁形成一旋转水环1,水环下部内表面与轮毂相切,沿箭头方向旋转,在前半转过程中,2BV水环式真空泵水环内表面逐渐与轮毂脱离,因此在叶轮叶片间与水环形成封闭空间,随着叶轮的旋转,该空间逐渐扩大,空间气体压力降低,气体自圆盘吸气口被吸入;在后半转过程中,水环内表面逐渐与轮毂靠近,叶片间的空间逐渐缩小,空间气体压力升高,高于排气口压力时,叶片间的气体自圆盘排气口被排出。

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。
3.真空泵油的选择、使用、更换及储存3.1 使用指定油品:本文中介绍的Oerlikon Leybold Vacuum品牌的标准油品,以及欧瑞康莱宝真空泵产品样本中所提到的油品,都是在我们工厂实验室内,对相应系列的各种泵,在各种使用条件下经过全面长期运行检验后定型的油品。

影响极限真空的因素
• 极限真空(有害空间的存在) 有害空间: 转子与泵腔的接触点到排气口之间的尖角地带,藏在这里并处于排气压强下不能被旋片推出泵腔之外的
气体,常被旋片通过间隙挤到吸入腔内,因而降低泵的极限真空。 旋片与转子、旋片与泵腔的接触点,这里的气体会因为压差的原因影响泵的极限真空。 真空泵油的作用就是填充有害空间以消除其对极限真空的影响。
中间辅助排气阀的设定
在双级泵中,若高真空级与低真空级之间是不等腔的结构(只是泵腔长度不 同),则需在两级中间通道上设置辅助排气阀。
原理图:

设定中间辅助排气阀的原因
举例说明:假设高真空级泵腔容积V1为低真空级泵腔容积V2的四倍,由于 是同轴旋转,故高真空级的抽速S1为低真空级抽速S2的四倍。由气体流量连续 性方程可知:P1S1=P2S2,又因S1/S2=4,所以P2/P1=4。由此看出,当高真 空级吸入压强P1为大气压时,其排气压强P2可达4个大气压,此时真空泵就变 成压气机了。由于真空泵配用的电机功率比压缩机小,因而工作困难。

莱宝油封式真空泵泵油使用说明
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.莱宝真空泵油的种类(品牌油牌号)---- 标准油品和特种油品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:z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)。
z润滑---相对运动件间的润滑,降低磨损。
z冷却---油在泵内与油箱间循环,散热、冷却。
z携裹---将磨损产生的尘粒或其它颗粒挟裹在油中,减小磨损伤害。
z保护---形成保护性油膜,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:z高温下饱和蒸汽压要低,易挥发成分要少。
z最低的水含量和吸水性。
z要有一定粘度,且随温度变化小(粘度温升曲线平滑)。
z润滑性能好,机械应力下具有良好的抗裂解性。
z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:z高温时的稳定性较差。
z化学反应(酸、碱、卤素)的惰性较差。
z遇强氧化剂时(氧气)的惰性较差。
z对非极性物质(蜡、油脂)的溶解性较差。
z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。
3.真空泵油的选择、使用、更换及储存3.1 使用指定油品:本文中介绍的Oerlikon Leybold Vacuum品牌的标准油品,以及欧瑞康莱宝真空泵产品样本中所提到的油品,都是在我们工厂实验室内,对相应系列的各种泵,在各种使用条件下经过全面长期运行检验后定型的油品。
