The new characteristics of rotary vane vacuum pump

new rotary vane vacuum pump is a kind of compulsory oil-free vacuum pump equipment, to solve the phenomenon of oil and oil before. The rotary vane vacuum water pump has the following features: 1.

Fully sealed structure

C direct coupling pump seal in the fuel tank is the world's only a motor rotary vane pump. This structure will completely eliminate the possibility of the leakage of the shaft end, and China is now almost all of the rotary vane vacuum pump oil leakage problems.

2。 Gas ballast valve with air cushion adjustment

air cushion is an effective method for eliminating noise vacuum pump, the pump structure design for the gas ballast valve regulating the function of the air cushion, a set of independent system on the gas ballast valve can adjust the air volume of the air cushion. In the actual debugging, we clearly feel the importance of this kind of structure for noise reduction.

3。 Rotary vane vacuum pump protection function complete

rotary vane vacuum pump itself has a ventilation valve, used in the pump stops, the valve is controlled by electromagnetic valve differential pressure valve, solenoid valve power is needed for the generator provided by the motor, thus the motor movement to determine whether the generator power generation, so as to determine whether the electromagnetic valve. In addition, the pump also has overload protection switch. Once the pump stuck or overload, abnormal motor current will rise. At this time, the protection switch will automatically cut off power supply. From the point of use, this feature is very useful.

4。 The rotary vane vacuum pump has a broad application range

this pump is suitable for the 50 hz, 60 hz and the three-phase 220 v, 380 v power supply system. This water pump has strong drainage capacity of steam. One reason is that it can keep high vacuum in the air. The second is the high oil temperature. When the normal operation of the oil temperature higher than 80 ° C. Such a high oil temperature and effective drainage of gas ballast pump steam is greatly increased. In particular, the pump can be used synthetic oil resistant halogen vacuum pump.
