Which gases can be extracted by liquid ring vacuum pump?

As is known to all, liquid ring vacuum pump has a high working efficiency, but many gases cannot be extracted. The following will introduce which gases can be extracted by liquid ring vacuum pump.

Which gases can be extracted by liquid ring vacuum pump

1. Gas generated in the process of vacuum system of liquid ring vacuum pump

This includes gases released by the materials in the process and gases introduced as required by the process, as well as gases evaporated by liquid or solid in the vacuum system.

2. Atmospheric gas originally existing in the vacuum system of liquid ring vacuum pump

The vacuum container chamber and vacuum tube circuit in the vacuum system of liquid ring vacuum pump originally contain a certain amount of atmospheric gas components. In the initial stage of pumping, they are the main gas load of the vacuum system.

3, liquid ring vacuum pump vacuum system leakage gas

The leakage gas includes the air leaking into the vacuum system through the connection of vacuum seal and various leakage channels.

4, liquid ring vacuum pump vacuum system material surface desorption released from the gas

The material surface in vacuum system of liquid ring vacuum pump can absorb and dissolve part of gas under normal pressure. At negative pressure, this part of the gas will be released again. Its air discharge rate is related to material performance, treatment process and material surface state.

5. The atmosphere penetrates through the wall material to the gas in the vacuum pump system of the liquid ring

A gas will dissolve and percolate in a solid. Therefore, the atmosphere will permeate some gas into the vacuum system through the structural material of the container wall of the liquid ring vacuum pump.

In the gas extracted by liquid ring vacuum pump, there are not only various gases generated in the working process, but also the air in the system and the gas permeated through the atmosphere. All these gases can be discharged through the work of liquid ring vacuum pump, thus improving the working efficiency.
