Water Ring Seal of Vacuum Pump Control

  •  


    Vacuum pumping of vacuum pumps mainly depends on the water-ring liquid seal in the pump body. The water-ring liquid seal determines the pumping rate and vacuum degree of the pump. Early water-ring liquid seals were nourishing flow.
    There are some problems in process control, economic operation and environmental protection of direct row.
    When C02 gas is sucked, industrial water can not be used to prevent scaling of equipment and pipelines. In addition, some enterprises have acid corrosion and Cl-corrosion in the operation system of vacuum pumps.
    Stainless steel lining and desalted water are used in the selection of pump body.
    (2) In addition, the maximum working fluid volume of 12 vacuum pumps is 155 m3/h at the same time. Considering economic operation and environmental protection, working fluid must be recycled. How to ensure the circulation of working fluid and
    Control, through demonstration, a feasible scheme is finally determined, that is, for the first time, four vacuum pumps are used to share one gas-water separator, and by adjusting the liquid level height of the gas-water separator, the control is true.
    The water level of the water ring liquid seal of the empty pump is good after putting into use.
    Pressure swing adsorption (PSA), as a physical adsorption decarbonization process, has obvious energy saving and emission reduction effects, but it also has the problem of effective gas yield. How to ensure that the yield is more optimized and the process runs more smoothly?
    It is necessary to summarize, perfect, optimize and improve constantly in the future production and operation so as to create better economic benefits for enterprises.
