Water ring pump

23 Apr 2018Email

Water ring pump, called water ring vacuum pump, is a rough vacuum pump. The ultimate vacuum that can be obtained is 2000~4000Pa, and the vacuum unit of the vacuum pump can reach 1~600Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which is a low pressure compressor with a pressure range of 1 to 2 x 10^5 Pa gauge.

water ring vacuum pump

The water ring vacuum pump is equipped with an eccentric rotor with fixed blades, which throws water (liquid) toward the stator wall, and water (liquid) forms a liquid ring concentric with the stator. The liquid ring and the rotor blade together form a variable volume. Volume vacuum pump.

 

The water ring pump was originally used as a self-priming pump and was gradually used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and food. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have been paid attention to in the acquisition of rough vacuum. Since the gas compression in the water ring pump is isothermal, the flammable and explosive gas can be removed, and the dusty and water-containing gas can be removed.

 

Characteristics
1. Easy to repair
The temperature of the compressed gas is low, and the exhaust gas temperature is only 10~15 °C higher than the intake air temperature. Because of this feature, it is easy to be suitable for pumping and feeding flammable and explosive gases.
2. Scope of application
Mainly used in coal mines (gas pumping), chemical, pharmaceutical, mining, paper, food, beer, building materials, plastics, metallurgy, electrical and other industries.
3. Flexible configuration
It can be assembled with separators, heat exchangers, pipelines, valves, instruments, and electronic control devices and placed on a chassis as a complete set of equipment.
