Water Ring Vacuum Pump is a device that uses various methods to generate, improve and maintain vacuum in a closed space. In the selection process, we need to refer to several performance parameters in order to select the appropriate equipment. The specific parameters learned from the Water Ring Vacuum Pump Suppliers are as follows:


1. Pressure

The pressure unit of the Water Ring Vacuum Pump is Pa, which means that the pump is equipped with a standard test hood at the inlet and works according to the specified conditions. It will tend to a stable pressure without introducing gas to work normally.


2. Pumping rate

The pumping rate unit is m3/s or l/s, which refers to the ratio of the flow rate of the gas flowing from the test hood to the equilibrium pressure measured at the specified position of the test hood when the pump is equipped with a standard test hood and works under the specified conditions . Referred to as the pumping speed of the pump.

3. Pumping capacity

Water ring vacuum pump suction unit is Pam3/s or Pal/s. Refers to the gas flow at the pump inlet.


4. Starting pressure

The starting pressure unit of the vacuum pump is Pa, which refers to the pressure when the pump starts without damage and has the function of pumping.


5. Fore-stage pressure of the pump

The pre-pressure unit of the vacuum pump is Pa, which refers to the outlet pressure of the vacuum pump whose discharge pressure is lower than one atmospheric pressure.

6. Fore-stage pressure of the pump

Water ring vacuum pump port pre-stage pressure unit is Pa, which means that it exceeds the pre-stage pressure that can damage the pump.


In short, the main parameters of the water ring vacuum pump are pressure, pumping rate, pumping volume, starting pressure, pre-stage pressure, etc., we can also understand the equipment through these parameters and can be more handy when using it.
