The characteristics of the newly developed rotary vane vacuum pump

Rotary vane vacuum pump is a mandatory oil vacuum pump equipment, a good solution to the emergence of the return of oil, fuel injection and other phenomena, has been recognized by the majority of users, the following characteristics:

1, fully sealed structure

C type direct coupled pump is the only one in the world to seal the motor in the tank. This structure will completely eliminate the possibility of the end of the shaft leakage, and China's current rotary vane vacuum pumps are almost all oil spills.

2, air conditioning with air cushion valve

Air cushion is an effective means to eliminate the noise of the pump, and the design of the structure of the gas pump valve can be adjusted to consider the function of the air cushion, a set of independent air conditioning system in the gas valve adjustable air volume. In the actual debugging, we obviously feel the importance of this structure to noise reduction.

3, pump protection function

The pump itself is equipped with an air outlet with the valve when the pump stops, the valve is composed of a solenoid valve control pressure differential valve, solenoid valve and electric power required by the motor generator, so the motor moving or not determines whether the power generator, which determines whether the action electric magnetic valve. In addition, the pump is also equipped with overload protection switch, once the pump is stuck or overloaded, the motor current will rise abnormally, then the protection switch will automatically cut off the power supply. From the use point of view, this feature is very useful.

4, the scope of application of the pump pump

Suitable for 50HZ, 60HZ and 220V, 380V power supply system. The steam pump drainage ability, one of the reasons is that gas town can still maintain a high degree of vacuum, the high oil temperature, oil temperature in normal working temperature is above 80 DEG C, so high and effective gas drainage capacity of the town, the steam pump is greatly improved. It is worth mentioning that, as long as the choice of synthetic oil pump can become resistant to halogen vacuum pump.
