1. Packing seal is to put the compressive and resilient packing into the packing box of liquid ring vacuum pump, which can be sealed by transforming the axial compressive force of the cover into the radial sealing force.
2. Oil seal is a self-tightening lip seal. It has simple structure, small size, low cost, convenient maintenance and small resistance torque. It can not only prevent medium leakage, but also prevent external dust and other harmful substances from entering the liquid ring vacuum pump.
3. The labyrinth seal of the liquid ring vacuum pump works well when the design is reasonable, the processing is fine, the assembly is intact and the rotating speed is high.
4. Power seal. When the vacuum pump is in operation, the pressure head produced by the auxiliary impeller balances the high-pressure liquid at the outlet of the main impeller, thus realizing seal.
