latest rotary vane vacuum pump

The newly developed rotary vane vacuum pump of our company is a vacuum pump equipment with compulsory oil prohibition. It solves the phenomena of oil return and injection before and is recognized by the majority of users. This rotary vane vacuum pump has the following characteristics:

1. Fully sealed structure

The C-type direct-coupled pump is the only rotary vane pump in the world that seals the motor in the oil tank. This structure will completely eliminate the possibility of shaft end leakage, and almost all rotary vane vacuum pumps in China have oil leakage problems.rotary-vane-vacuum-pumps

2. Air ballast valve with air cushion adjustment

Air cushion is an effective means of eliminating pump noise, and the function of adjustable air cushion is taken into account in the structure design of the air ballast valve of the pump. An independent system on the air ballast valve can adjust the air volume of the air cushion. In actual debugging, we obviously feel the importance of this structure for noise reduction.

3. The protection function of the pump is complete.

The pump itself is equipped with an exhaust stop valve, which is controlled by a solenoid valve, and the electric energy required by the solenoid valve is supplied by the generator with the motor. In this way, whether the motor moves or not determines whether the generator generates electricity and whether the solenoid valve operates or not. In addition, the pump also has an overload protection switch. Once the pump is stuck or overloaded, the motor current will rise abnormally. At this time, the protection switch will automatically cut off the power supply. From a usage point of view, this function is very useful.piston-vacuum-pump-structure


4. The pump has a wide range of applications.

Applicable to 50HZ, 60HZ and three-phase 220V, 380V power supply system. One of the reasons for the strong steam drainage capacity of the pump is that it can still maintain a high vacuum in the gas town. The other is that the oil temperature is high, and the oil temperature is above 80 C in normal operation. With such a high oil temperature and an effective gas town, the steam drainage capacity of the pump is greatly improved. In particular, it is worth mentioning that the pump can become a halogen-resistant vacuum pump as long as synthetic oil is selected.liquid-ring-compressor
