Set up and operation 4.2 Description The C-VLR model range has a connecting thread on the suction side and an exhaust silencer on the pressure side. With the C-VLR 60 the incoming air is cleaned by a filter cartridge. The C-VLR 100-500 have a micro filter on the suction side. The ZEPHYR C-VLR is a double shaft rotary piston vacuum pump in which the claws roll off against each other contact free and dry. The counter-rotating claw rotors are synchronised by a gear pair in the gearbox.
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... 4/H), oil sight glasses (Fig. 2/I...
Installation 5.3 Connecting pipes a) Vacuum connection at (Fig. 2/A... 4/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 (ZSZ) at (Fig. 2/B... 4/B) or conducted away using a hose or a pipe.
Installation 5.5 Filling with lubricating oil a) Fill the lubricating oil (for suitable types see “Maintenance”) for the gear wheels and oil filling point (Fig. 3/H) up to the middle of the sight glasses (Fig. 3/I). b) Close the oil filling point. 5.6 Connecting the motor DANGER Danger of death if the electrical installation has not been done professionally. The electrical installation must only be done by a qualified electrician observing EN 60204. The operating company has to provide the main switch.
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... 4/Q) may go above 70°C. You must avoid touching the hot surfaces (marked with warning plates).
Commissioning and decommissioning 6.1.1 Checking the rotation direction The intended direction of rotation of the drive shaft is shown by the rotary direction arrow (Fig. 2/O... 4/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 anti-clockwise. NOTICE Incorrect direction of rotation Operating in the wrong direction of rotation leads to damage to the machine.
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 and lubricating H M I Fig. 6 Changing the oil K Changing the oil: H Oil filling point NOTICE I Oil sight glass K Oil discharge point M Oil recommendation plate 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 L M1 L Fig. 7 Lubrication H Oil filling point I Oil sight glass K Oil discharge point L Grease nipple M1 Lubrication plate K I H Lubrication: The bearings on the C-VLR 400 / 500 must be lubricated with 30 g of grease every 5,000 operating hours or after no more than 2 years (see the two grease nipples (Fig. 7/L)). We recommend Klüber PETAMO GY 193 or other similar greases (see lubrication plate (Fig. 7/M1)).
Maintenance and repair 7.2.2 Air filtering NOTICE f2 Insufficient maintenance on the air filter The power of the machine lessens and damage may occur to the machine. Vacuum tight suction filter (C-VLR 60) The filter cartridge (Fig. 8/f2) for the suction filter (Fig. 2/S) must be cleaned monthly or more often depending on the level of contamination by purging from the inside outwards. In spite of cleaning the filter its separation efficiency will continue to deteriorate.
Maintenance and repair 7.2.3 Coupling The coupling sprocket (Fig. 10/k, 11/k)) is subject to wear and must be checked regularly (at least once a year). q k s4 CAUTION n1 Defective coupling sprocket Defective sprockets may lead to the rotor shaft breaking. m Fig. 10 To check the coupling switch the motor (Fig. 10/m, 11/m) off and ensure that it cannot be switched on again. C-VLR 60 Undo the screws (Fig. 10/s4) on the housing flange (Fig. 10/n1) .
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).
