1. water ring vacuum pump (water ring pump for short) model is determined according to the different process requirements. Need main technical parameters of the process required in the process of vacuum extraction rate (i.e., pumping speed), to reach the limit of vacuum (vacuum), in the process of work pressure, connecting the actual working condition of the reaction kettle of water ring pump condition, the nature of the smoke gas, equipped with the protection grade of the motor, the working process of the situation of the connecting line and the working fluid temperature change.
2. The factors affecting the pumping speed of the water ring pump are: the temperature change of the material in the reaction kettle, the change of the water vapor produced, the pressure in the working environment and the length, thickness and tightness of the connecting pipeline, etc.
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. These need to be calculated in the process of selecting the water ring pump, otherwise the water ring pump will not meet the requirements of the process.
4. When choosing the water ring pump material, the corresponding material should be selected according to the nature of the pumped gas. When choosing the water ring pump connection mode and how much the motor is equipped, the actual vacuum requirements generated in the actual application process of the water ring pump should be considered.
As long as you can pay attention to the above points, you can choose the right type of water ring pump.
The vane vacuum pump (referred to as the vane pump) model is similar to the selection of water ring pump models. One thing that needs special attention is that the vane pump can not be used as a compressor, and the vane pump can not face the atmosphere for a long time to breathe.
