Onlyuse flexible vacuum hoses for connecting Rotary Vane Pumps.• The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopesdownwards, so allowing condensate to flow out of the pump. Collect the condensate anddispose of it in an environmentally compatible manner.• Maintain a space of least 20 cm between the pump and adjacent parts in order to enablethe pump to cool.CAUTION !Solid particles in the pumping medium impair the pumping action and can lead todamage. Prevent solid particles penetrating into the pump!302316 7Basic Safety InstructionsSubstances2.4 HazardousCAUTION !The operating company bears the responsibility for the use of the rotary vane pump.Hazardous substances in the gases to be pumped can cause personal injuries and property damage. Pay attention to the warning notices for handling hazardous substances.The local regulations apply in foreign countries.Combustible GasesExamine before switching on whether that can form gas combustible gas/air mixtures which can be promoted! Consider the regulations of the guideline 1999/92/EC.It is not permitted to pump gases that are combustible or prone to explosion.Aggressive gasesThe rotary vane pumps is not certified according to ATEX guidelines 94/9/EC.Poisonous gasesUse a separator when pumping poisonous or harmful gases. Prevent such substances from leaking out of the appliance or pump. Treat these substances according to the applicableenvironmental protection regulations.Test the strength and leak-tightness of the connecting lines and the connected apparatus.Prevent environmental poisons, e.g. mercury, getting into the rotary vane pumps.Fulfil the requirements, for example:• German Hazardous Substances Regulation (GefStoffV) of 23. December 2004• Regulations 2006/121/EC (classification, packaging and identification of hazardous sub-stances),• Manufacturer's safety data sheets on hazardous substances.Temperatures2.5 HighThe rotary vane pump may heat up as a result of the temperature of the gas being pumpedand through intrinsic heating. The temperature of the rotary vane pump heads can reach80 °C during operation.Prevent the following maximum permissible temperatures from being exceeded.• + 40 °C for the environment, and• + 20 °C for the gas to be pumped.The motor is protected against overload by a suitable protective device.8 302316Description3 Description3.1 DesignThe ILMVAC P - Z series vacuum pumps are oil-sealed, two-stage rotary vane vacuumpumps.The drive motor is directly flange-mounted onto the motor cover of the pump holder.The pump shaft and the motor shaft are connected to each other by an elastic coupling.The bearings of the interior pump body are force-fed lubricated sliding bearings.1 Rotary knob for setting the gas ballast valve(direction of rotation: to the left = open, to the right = closed)2 Screw-plug for oil filling3 Type plate4 Oil inspection glass5 Oil drain screw-plug6 On / Off switch7 Drive motor8 Suction port9 Exhaust portFig. 1 Rotary Vane Pump P 23 Z3.1.1 Advantages• extremely compact construction and consequently small dimensions and low weight• vacuum pump is sealed after switching• quite running with low intake pressures• a gas ballast valve enables condensing vapours to be pumped out, it achieves a high tolerance ofwater vapour pressure• Suction and exhaust ports are designed with small flanges according to pneurop standard• The oil level can be checked on the oil level gauge• Important parts are easy to service and replace• The powerful oil circuit strengthens the purging and cleans the pump of particles of dirt and con-densates.• The rotary vanes are made of a special plastic. They are not affected by corrosion and not dam-aged by dirt particles and have very good sliding properties.• All elastomer seals are made of Viton.302316 9Description3.2 Area of ApplicationThe range of application of our oil-sealed rotary vane pumps encompasses the entire field of vacuum technology, both for use in the laboratory and in industry.The task is to create end pressures (partial) down to around 10 -4 mbar• as a single pump• as a fore-pump for oil diffusion pumps or as turbo-molecular pumps.The rotary vane pump can pump out biological, toxic and radioactive gases and vapours,and evacuate containers or vacuum installations up into the high vacuum range.Description The pump body is subdivided into several chambers by the eccentrically arranged rotorwhich has two radically sliding vanes. The volume of each chamber changes cyclically as the rotor turns. This sucks the gas into the intake opening. The gas flows through the dirt filter,which is connected to the centring ring, into the pump body. After the intake opening is clo-sed by the vane, the gas is transported onwards and compressed.A dosed quantity of air (gas ballast) can be let into the pump body during the compression byopening the gas ballast valve. This prevents vapours condensing in the vacuum pump.The maximum tolerance of water vapour pressure is 40 mbar.Oil is injected into the pump body for sealing and lubrication. An oil pump pumps oil out ofthe oil reservoir into a pressure oil lubrication system that feeds all the bearings. The low-mounted oil suction pipe achieves a large usable oil reserve.At the outlet valve, the compressed gas is pumped out of the pump body through the ex-haust port. The oil carried along with the gas is separated out by a filter (accessory).3.3.2 Vacuum-tightness when switching off the suction port valveVacuum-tightness when the pump is switched off is achieved by means of the hydraulicallyactuated suction port valve (HV-valve).The hydraulically actuated suction port valve closes the suction port vacuum-tight when theunit is shut down. This prevents venting and oil flowing back into a connected receptacle.1 Hydraulic piston2 Valve disk3 Pull-back spring4 Suction opening5 Venting holeFig. 3 Suction port valve (HV-valve)Descriptionballast3.3.3 GasCAUTION !Condensable vapours may only be extracted when the gas ballast valve is open,when the vacuum pump is at operating temperature and within the limits of the ma-ximum tolerance of water vapour pressure!Condensation occurs if the maximum water vapour pressure tolerance of 60 mbar isexceeded.When pumping condensable vapours, they may be compressed during the compressionphase above the saturated vapour pressure and condense.This causes considerable deterioration in the vacuum pump’s performance:• ultimate pressure is not achieved• corrosion occurs• heavy oil contamination and formation of emulsions.When the gas ballast valve opens (to the left), air flows into the compression space. The airflowing in keeps the partial pressure of the condensable medium so low that the pressureneeded to open the outlet valve is reached before the medium condenses.CAUTION !Operating with gas ballast increases the operating temperature of the vacuum pumpby 5 – 10 K.Should condensate form despite actuation of the gas ballast device, the suction port must be closed and the pump operated with gas ballast for a lengthy period (about 2 hours).3.4 Scope of DeliveryThe scope of delivery is specified in the supply contract.Description 3.5 Accessoriesoptional3.5.1 Overview and order numbersDescription Order no.Condenser AKS 16 (suction side) Condenser AKD 16 (pressure side) Condenser AKS 25 (suction side) Condenser AKD 25 (pressure side)300883 300884 300885 300886Replacement cartridge for AKD 16 and AKD 25 800160 Main stream oil filterOPF 40 M (for filtering solid particles)OPF 40 C (for neutralizing acidic ingredients in the oil)700153-02 700153-01Replacement cartridge for OPF 40 M Replacement cartridge for OPF 40 C 800170 828599Oil “LABOVAC 10” 1 litre 8001225 litres 80012010 litres 80012320 litres 800124200 litres 8001193.5.2 Condenser AKS 16 and AKS 25The suction-side condensate separator prevents condensates from the vacuum systems pe-netrating into the pump.It is directly flange-mounted onto the suction port of the pump by means of a DN 16 KFand/or DN 25 KF connector set.

Set the rotary vane pump on a flat and horizontal surface.2. Remove the protective caps on the suction and pressure ports.3. Close the vacuum connection on the suction port and the exhaust pipe on the pressureport. The suction and pressure ports must not be connected the wrong way round by mis-take!4. Connect the rotary vane pump to the electrical supply.Regularly check and clean the air inlet of the motor ventilator.The structural elements used on the inlet and outlet sides must be resistant to the media tothe pumped. The pressure on the outlet side must not exceed 0.5 bar!A pressure that is slightly below the air pressure helps to avoid pollution of gases, and re-duces corrosion.Installation and Operation 5.4 Connecting to the electricity supplyThe standard pump is supplied with complete electrical wiring. It is connected via an appli-ance cable and a power supply plug.WARNING !Should the user change the electrical connection, for example for fitting into a sys-tem, then this may only be performed by a skilled worker under observance of theaccident prevention regulations.It is generally suggested to protect the motor by 120 per cent of is rated power in considera-tion of the starting and switch-on response.With pumps with three-phase motor, the direction of rotation of the motor must be checkedbefore starting the vacuum pump for the first time.The vacuum pump may be destroyed if the motor rotates in the wrong direction.Device connection cables and plugs must comply with the requirements of the line discon-nection devices (current, output).The customer/user shall install the main and emergency stop switches.5.4.1 Type of motor protectionAll A.C. motors are provided with a thermal overload protection ex works, protecting the mo-tor and vacuum pump from damage or destruction, respectively.All poles of three-phase motor must, as it were, be protected by cut-outs.5.5 Selecting the operating oil5.5.1 Importance for the choice of the right oilWARNING !We recommend the use of LABOVAC Oils. These special oils are not harmful tohealth when used properly!The oil fulfills the following functions in the vacuum pump:• Lubricating the sliding parts, such as rotor, vane, radial shaft seals• Sealing the moving parts against the stator wall to reduce leaks• Conducting the heat of compression to the metal walls (cooling).。

水环式真空泵全解析，有图、有动画1.水环式真空泵是带有多叶片的转子偏心装在泵壳内。
当它旋转时，把液体抛向泵壳并形成与泵壳同心的液环，液环同转子叶片形成了容积周期变化的旋转变容真空泵。
当工作液体为水时，称水环式真空泵。
水环真空泵就是这种靠偏置叶轮在泵腔内回转运动使工作室容积周期性变化以实现抽气的真空泵。
它的工作室由旋转液环和叶轮构成，其结构和工作原理与液环压缩机相似。
下面这个3D动画比较直观：水环真空泵工作原理水环泵工作轮2在泵体1中旋转时形成了水环3和工作室5，水环与工作轮构成了月牙形空间。
右边半个月牙形的容积由小变大，形成吸气室。
左边的半个月牙形的容积由大变小，构成了压缩过程(相当于排气室)。
被抽气体由进气管8和进气口4进入吸气室。
转子进一步转动，使气体受压缩，经过排气口6和排气管7排出。
排出的气体和水滴由排气管道7进入水箱10，此时气体由水中分离出来，气体经管管道9排到大气中，水由水箱进入泵中，或经过管道11排到排水设备中。
当工作液体为水时，称水环式真空泵，水环真空泵是一种粗真空泵，它所能获得的极限真空为2000~4000 Pa，串联大气喷射器可达270~670 Pa。
水环真空泵示意图：当叶轮按图中顺时针方向旋转时，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。
水环的下部分内表面恰好与叶轮轮毂相切，水环的上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和叶片数目相等的若干个小腔。
如果以叶轮的下部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。
水环真空泵（简称水环泵）是一种粗真空泵，它所能获得的极限真空为2000~4000Pa，串联大气喷射器可达270~670Pa。
