In order to let you better use the 2BV water ring vacuum pump, today I compiled some information about its sealing form for you, let's have a look!
1. Oil seal is a self tightening lip seal, which 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 2BV water ring vacuum pump.
2. Power seal: when the vacuum pump is in operation, the pressure head generated by the auxiliary impeller balances the high-pressure liquid at the outlet of the main impeller, so as to realize the seal.
3. The labyrinth seal of 2BV water ring vacuum pump has a good effect when the design is reasonable, the processing is excellent, the assembly is complete and the rotating speed is high.
4. Packing seal is to put the packing rich in compressibility and resilience into the packing box of 2BV water ring vacuum pump, and convert the axial pressing force of the gland into radial sealing force, so as to play a sealing role.
The sealing of 2BV water ring vacuum pump is mainly to improve the efficiency of the equipment. When sealing, you can choose any method.
