1. The determination of the model of the water ring vacuum pump (referred to as the water ring pump) is determined according to the different process requirements. The required technical parameters mainly include the required pumping rate (ie, pumping speed) during the process of vacuuming the process, the ultimate vacuum to be achieved (ie, vacuum degree), the external pressure during the working process, and the pressure of the reactor connected to the water ring pump. The actual working conditions, the nature of the pumped gas, the protection level of the equipped motor, the condition of the connecting pipeline during the entire working process, and the temperature change of the working fluid.

2. The factors affecting the pumping speed of the water ring pump are: the temperature change of the material in the reactor, the change of the generated water vapor, the pressure in the working environment, the length, thickness, and sealing of the connecting pipeline, etc.

3. Factors affecting the vacuum degree of the water ring pump include: the change value of the pressure in the reactor, the change of the pumping rate, and the change of the objective conditions in the actual application process, all of which need to be calculated in the process of selecting the water ring pump. Otherwise, the selected water ring pump will not meet the requirements of the process.

4. When selecting the material of the water ring pump, the corresponding material should be selected according to the nature of the pumped gas. When selecting the connection mode of the water ring pump and the size of the motor equipped, the actual vacuum degree generated during the actual application of the water ring pump should be considered Require.

As long as you can pay attention to the above points, you can choose the correct type of water ring pump.

The determination of the model of the rotary vane vacuum pump (referred to as the rotary vane pump) is similar to the selection of the model of the water ring pump. One thing that needs special attention is that the rotary vane pump cannot be used as a compressor, and the rotary vane pump cannot face the atmosphere for a long time.
