Application Range of Liquid Ring Vacuum Pump

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

1. The liquid-ring vacuum pump can work continuously for a long time in the ambient temperature range of 5-40 C and the inlet pressure less than 1330 Pa.

2. The liquid ring vacuum pump is not suitable for pumping gases containing excessive oxygen, toxic, explosive, corrosive to metals, chemical reactions to pump oil, and particulate dust. It is also not suitable for transporting gases from one container to another for transporting pumps.

3. The continuous working time of the liquid ring vacuum pump under the inlet pressure from atmospheric pressure to 6000Pa is not more than 3 minutes, so as to avoid damage of the pump caused by oil injection or poor lubrication.
