Research on Liquid Drainage Operation of Liquid Separating Tank of Dry Vacuum Pump

Improvements of liquid drainage operation of liquid separating tank of dry vacuum pump were discussed from the perspective of inherent safety to prevent the liquid from entering the dry vacuum pump to cause the liquid interlocking parking and mechanical component damage. According to the field measurement data of pipeline layout, the result calculated by basic equation shows that using the steam jet pump 0# liquid separating tank can realize the continuous drainage operation of dry vacuum pump liquid separating tank. Finally, the implementation process of the dry vacuum pump liquid separating tank continuous drainage operation was compiled, and advantages of the mechanical vacuum system continuous drainage operation were listed. The improvement increased the mechanical safety and stability of the vacuum system, and achieved the purpose of protecting dry vacuum pump.
