Water ring vacuum pump (abbreviated as water ring pump) is a crude vacuum pump. The ultimate vacuum it can obtain is 2000~4000Pa, and the serial atmospheric ejector can reach 270~670Pa. Water ring pumps can also be used as compressors, known as water ring compressors, which are low pressure compressors with a pressure range of 1 to 2 x 105 Pa gauge pressure.
advantageThe structure is simple, the manufacturing precision is not high, and it is easy to process.
Compact structure, high rotation speed of the pump, generally can be directly connected with the motor, no need to reduce the device. Therefore, with a small structure size, a large displacement can be obtained, and the footprint is also small.
The compressed gas is essentially isothermal, ie the process temperature of the compressed gas changes very little.
Because there is no metal friction surface in the pump chamber, it is not necessary to lubricate the pump and the wear is small. The seal between the rotating part and the fixing part can be done directly by the water seal.
Inhale evenly, stable and reliable work, simple operation, easy maintenance.
