Control of liquid seal in water ring of vacuum pump

The vacuum pumping of vacuum pump mainly depends on the water ring liquid seal in the pump body. The level of water ring liquid seal determines the pumping rate and vacuum degree of the pump. In the early stage, the liquid seal of water ring is of direct discharge mode, which has problems in process control, economic operation and environmental protection.

① In order to prevent scaling of equipment and pipelines, industrial water shall not be used during the suction of C02 gas. In addition, some enterprises have acid corrosion and Cl corrosion in their vacuum pump operation system, so the pump body is lined with stainless steel and desalted water is used in selection.


② In addition, the maximum working fluid volume of 12 vacuum pumps is 155m3 / h when they are operating at the same time. Considering economic operation and environmental protection, the working fluid must be recycled. How to ensure the circulation and control of working fluid? Through demonstration, a feasible scheme is finally determined, that is, four vacuum pumps are used for the first time to share one gas-water separator. By adjusting the liquid level of the gas-water separator, the water ring liquid seal level of the vacuum pump is controlled, and the effect is good after being put into use.

As a physical adsorption decarbonization process, PSA has obvious energy saving and emission reduction effect, but it also has the problem of effective gas yield. How to ensure a more optimized yield and a more stable process operation needs to be summarized, improved, optimized and improved in the future production operation to create better economic benefits for enterprises.
