Compared with other types of mechanical vacuum pump, water ring vacuum pump has the following advantages
1. The structure is relatively simple, the manufacturing accuracy is not high, and it is easy to process. The operation is relatively simple and the maintenance is convenient.
2. Compact structure, the pump is usually directly connected with the motor, and the number of revolutions is high. Using smaller structure size, larger exhaust volume can be obtained.
3. There is no metal friction surface in the pump cavity of water ring vacuum pump, so there is no need to lubricate the pump. The sealing between the running part and the fixed part can be directly completed according to the water seal.
4. The temperature change of compressed gas in the pump cavity of water ring vacuum pump is very small, which can be considered as isothermal compression, so it can extract flammable and explosive gas.
