Rotary-type oil-free vacuum pump, the air volume is relatively large, the maximum vacuum can reach -84KPA above, such as model WZB80-P-VB-03, 25 said the size of the pumping speed, which is V that vacuum, B said exhaust ,
01 said two-phase power 220V, 03 said three-phase power 380V.
Oil-free vacuum pump structural features:
Oil-free vacuum pump direct rotary vane vacuum pump, is a rotary vane single-stage vacuum pump. Used to remove the gas from the sealed container to obtain the basic equipment for the vacuum. The pump can be used for air conditioning, repair of refrigeration equipment, suction equipment for medical equipment, printing machinery, vacuum packaging, vacuum blistering, physical and chemical experiments and small vacuum devices requiring vacuum environment. Can also be used as a small oil booster pump, oil diffusion pump, molecular pump and other pre-pump use. Oil-free vacuum pump is not suitable for the removal of ferrous metal corrosion, the chemical reaction of the pump oil, dust containing particles of dust, and oxygen is too high, explosive toxic gases. And can not be used as a transfer pump (ie, from one container to another).
The use of oil-free vacuum pump maintenance:
1, should have sufficient good ventilation conditions and below 40 ° ambient temperature.
2, no dust and dirt clean places.
3, no water, oil and other liquid will fall to the pump.
4, not directly exposed to the sun.
5, there is enough space around the pump can facilitate the inspection, maintenance and assembly and disassembly.
6, the pump must be installed on a flat surface.
7, it is best to pump on a similar concrete hard foundation to install, if there is no conditions, the pump can also be firmly installed in steel or wooden rack.
8, must ensure that the pump is not strong due to the foundation caused by vibration.
9, with the pump connected pipe should not be too long and less than the pump inlet diameter, the impact of pumping speed, with the attention of the vacuum pipe to check whether the leak.
10, then the wire, should pay attention to the motor nameplate on the provisions of the wiring requirements. Three-phase pump should pay attention to the direction of rotation of the motor should be aligned with the direction of the arrow on the pump.
