Water ring vacuum pump and rotary vane vacuum pump

Water ring vacuum pump and rotary vane vacuum pump are commonly used in industry, and they have similarities in some fields, so people can not choose their own products. But after understanding the difference between the two, it is helpful for us to choose and buy. The main differences between them are as follows:

1. water ring vacuum pump working process:

It needs external cooling water in its working process. The process of working medium transferring energy is as follows: in the process of suction, working medium increases the speed of movement (thus gaining kinetic energy from impeller) driven by impeller, flows out from impeller, and sucks gas from suction port; in the process of compression, working medium velocity decreases, and returns to impeller, pressure rises, and gas is absorbed. Compressed. It can be seen that during the whole working process, the working medium receives the mechanical energy from the impeller and converts it into its own liquid kinetic energy, then the liquid kinetic energy is converted into the pressure energy of the liquid, and the gas is compressed to do work, so that the liquid energy is finally converted into the energy of the gas.rotary-vane-vacuum-pump-buying-guide

2. rotary vane vacuum pump working process:

Rotary vane vacuum pump and water ring vacuum pump are opposed to prohibit the suction of gas containing water or steam, such as containing water will pollute the vacuum oil inside the rotary vane vacuum pump, inverted vacuum pump injection vacuum degree can not reach, long time will damage the vacuum pump components.liquid_ring_vacuum_pump

Types and characteristics

1. Types and characteristics of rotary vane vacuum pumps

Rotary vane vacuum pump mainly includes: Rotary vane vacuum pump is one of the basic equipment used to extract the gas from the closed container. It can be used alone or as the first parts of booster pump and molecular pump. This type is widely used in vacuum pump smelting, vacuum plating, vacuum heat treatment and vacuum drying in metallurgy, machinery, electronics, chemical industry, petroleum, medicine and other industries.

2. Types and Characteristics of Water Ring Vacuum Pumps

Water-ring vacuum pumps mainly include SK water-ring vacuum pump, ska direct-connected vacuum pump, 2SK double-stage water-ring vacuum pump and 2BV stainless steel water-ring vacuum pump. These pumps are mainly used in the process of rough vacuum and large air-pumping capacity. The vacuum pumps made of cast iron mainly pumps non-corrosive gases. The new stainless steel and glass steel can transport corrosive gases.Roots_Vacuum_Pump
