Set up and operation 4.3 Areas of application The screw vacuum pumps are suitable for the evacuation of closed systems or for a continuous vacuum within the following intake pressure ranges: 0.1 to 1000 mbar (abs.). They are also particularly suitable for feeding in extremely damp gases. The water vapour compatibility is very high. The maximum pumping capacity with free suction is 320 m3/h at 50 Hz. Data sheet D 832 / 42 shows the dependency of the pumping capacity on the intake pressure.
Set up and operation 4.4 Cooling the machine 4.4.1 Continuous flow cooling (Standard version) U7 U4 U2 With continuous flow cooling water flows continuously through the cavity in the double walled compressor housing. For safety reasons the cooling system is fitted with a solenoid valve, temperature control and a safety valve. A special control unit and a thermostatic water valve are obtainable. U1 D Temperature control Monitors the temperature of the cooling water.
Set up and operation 4.4.3 Circulation cooling (option) Fig. 7 Closed circuit water cooling (option) F F 580 mm Y C2 E D2 65 0m m Fig. 8 Circulation cooling system (option) 580 mm The cooling circuit is fitted with thermostat-controlled three-way valves. This enables diversion of water past the heat exchanger during the pump start-up phase. During operation of the pump, a temperature switch monitors the water temperature and a flow switch controls the flow rate.
Installation 5 Installation 5.1 Preparing for installation Check the following points: • • • • • Machine freely accessible from all sides Do not close ventilation grids and holes Sufficient room for installing and removing pipes and for maintenance work, particularly for installing and dismantling the machine No external vibration effects Do not suck any hot exhaust air from other machines into the cooling system. The oil filling point (Fig. 2/H, H1), oil sight glass (Fig.
Installation 5.3 Connecting pipes a) Vacuum connection at (Fig. 2/A, 3/A). NOTICE Material damage resulting from the forces and torques of the pipes on the unit being too high. Only screw pipes in by hand. The pumping capacity of the vacuum pump is reduced if the suction pipe is too narrow and/or too long. b) The discharged air can be blown out through the exhaust silencer at (Fig. 3/B) or conducted away using a hose or a pipe. NOTICE The air vent (Fig. 3/B) must not be closed or restricted.
Installation 5.4 Connecting the cooling water pipe NOTICE Cooling water control! The vacuum pump must not be operated without cooling water control. Danger breakdown of the pump Ensure that the cooling water stream is not interrupted. a) Connect the cooling water pipe to the cooling water inlet (Fig. 3/C) and the cooling water discharge pipe to the cooling water outlet (Fig. 3/D).
Installation b) When connecting a circulating cooling system to an external cooling system, it must be filled with cooling fluid. NOTICE Rinse the pipe network on the customer side before connecting it A filter element must be installed in the pipe network to prevent foreign bodies getting into the heat exchanger. Risk of frost damage in the cooling system Freezing cooling water may lead to extensive damage to the machine. Therefore mix the cooling water with at least 10 % of anti-freeze.
Installation 5.6 Connecting the motor DANGER Danger of death if the electrical installation has not been done professionally! The electrical installation may only be done by a specialist electrician observing EN 60204. The operating company has to provide the main switch. a) The motor‘s electrical data is given on the data plate (Fig. 3/N) or on the motor data plate (Fig. 2/ P1). The motors comply with DIN EN 60034 and are in protection class IP 55 and insulation class F.
Commissioning and decommissioning 6 Commissioning and decommissioning 6.1 Commissioning WARNING Improper use May lead to severe or fatal injuries. Therefore be sure to obey the safety instructions. CAUTION Hot surfaces When the machine is at operating temperature the surface temperatures on the components (Fig. 2/ Q) may go above 70°C.
Commissioning and decommissioning 6.1.1 Checking the rotation direction The drive shaft direction of rotation is shown by the rotation direction arrow (Fig. 2/O) on the motor flange. a) Start the motor briefly (max. two seconds) to check the direction of rotation. When looking at the motor fan, it must rotate clockwise. NOTICE Incorrect direction of rotation Operating in the wrong direction of rotation leads to damage to the machine.
Commissioning and decommissioning 6.2 Decommissioning/ storing Stop the machine a) Switch the machine off. b) If available close the cut off device in the suction and pressure pipe. c) Disconnect the machine from the electricity source. d) Depressurise the machine: Open the pipes slowly The pressure reduces slowly. e) Remove the pipes and hoses. f) Seal the connections for suction and discharge nozzles with adhesive foil. g) Discharge cooling water (Fig. 3/D1). see also Section 3.2.1, Page 11 6.
Maintenance and repair 7 Maintenance and repair DANGER Danger of death from touching live parts! Before maintenance work disconnect the machine by pressing the main switch or unplugging it and ensure that it cannot be turned on again. WARNING Hot surfaces and equipment During maintenance work there is the danger of getting burnt on hot components (Fig. 2/Q) and by the machine lubricating oil. Wait for the machine to cool down. 7.
Maintenance and repair 7.2.1 Changing the oil H M H1 M I1 K1 I Fig. 9 Changing the oil H, H 1 Oil filling point I, I 1 Oil sight glass K, K1 Oil discharge point M Oil recommendation plate K NOTICE Always change the oil when the machine is at operating temperature and in an atmospherically ventilated area. If it is not completely emptied the amount that can be refilled is reduced. The waste oil must be disposed of in compliance with the local environmental protection regulations.
Maintenance and repair 7.2.2 Air filtering s1 f1 D U Fig. 10 Air filtering D Suction flange f1 Mesh filter s1 Screws U Gas ballast valve NOTICE Insufficient maintenance on the air filter The power of the machine lessens and damage may occur to the machine. Intake air filter: The mesh filter (Fig. 10/f1) must be cleaned by rinsing out or purging or replaced more or less often depending on how dirty the discharged medium is. Remove the suction flange (Fig. 10/D) after undoing the screws (Fig. 10/s1).
Maintenance and repair h1 f3 f4 Fig. 11 Gas ballast valve filter: The pumps work with a gas ballast valve (Fig. 10/U). The inbuilt filter disc Fig. 11/f3) and micro filter discs Fig. 11/f4) must be cleaned more or less often by purging depending on how dirty the medium flowing through is. By undoing the countersunk screw (Fig. 11/g1) and removing the plastic cover (Fig. 11/ h1) the filter parts can be removed for cleaning. Re-assemble in reverse order.
Maintenance and repair 7.2.3 Coupling The coupling sprocket (Fig. 13/k) is subject to wear and must be checked regularly (at least once a year). s5 CAUTION k n m q Fig. 13 Coupling Defective coupling sprocket Defective sprockets may lead to the rotor shaft breaking. To check the coupling switch the motor off and ensure that it cannot be switched on again. Suspend the motor (Fig. 13/m) on the eyebolt by means of lifting equipment. Undo the screws (Fig. 13/s5) on the motor flange.
Maintenance and repair 7.3 Repair/ Service a) For on site repair work the motor must be disconnected from the mains by a qualified electrician so that it cannot be started up again accidentally. For repairs use the manufacturer, its branch offices or authorised dealers. Please contact the manufacturer for the address of the service centre responsible for you (see Manufacturer‘s address).
