Determination of the model of water ring pump and rotary vane pump

1. 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 pumping rate (ie, pumping speed) required in the vacuuming process of the process, the ultimate vacuum to be achieved (ie, the degree of vacuum), the external pressure during the working process, and the reaction kettle connected to the water ring pump. The actual working conditions, the nature of the pumped gas, the degree of protection of the motor, the connection of the 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 amount of water vapor generated, the pressure in the working environment, and the length, thickness and sealing of the connecting pipe.

3. The factors affecting the vacuum degree of the water ring pump are: 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, 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 how large the motor is equipped, the actual vacuum generated during the actual application of the water ring pump should be considered. Claim.

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

The specification of the rotary vane vacuum pump (referred to as the rotary vane pump) is similar to the choice of the water ring pump model. It is important to note that the rotary vane pump cannot be used as a compressor, and the rotary vane pump cannot inhale for a long time.
