Liquid ring vacuum pump and rotary vane vacuum pump difference

The main differences between liquid ring pump and rotary vane pump are as follows:

1. In the working process of liquid ring vacuum pump, the liquid ring vacuum pump needs external cooling water. The working medium transmits energy in the process of suction: in the process of suction, the working medium increases the speed of motion (thus obtaining kinetic energy from the impeller), flows out of the impeller, and draws air from the suction port at the same time; in the process of compression, the speed of the working medium decreases, and returns to the impeller at the same time, and the pressure rises, The gas is compressed.

It can be seen that in the whole working process of the liquid ring vacuum pump, the working medium plays a role in receiving the mechanical energy from the impeller and converting 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 work, so as to finally convert the liquid energy into the gas energy.

2. Contrary to liquid ring vacuum pump, it is forbidden to pump gas containing water or steam. If water is contained, it will pollute the vacuum oil in the rotary vacuum pump. If the vacuum degree of oil injection of the inverted vacuum pump is not reached, the vacuum pump parts will be damaged after a long time.

There are many types of vacuum pumps, which are widely used in various fields, such as plastic machinery, agricultural chemical industry, dye chemical industry, low temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, vacuum pump equipment, petrochemical industry, laboratory, etc. the typical application of vacuum pump is as follows.

3. Types and characteristics of rotary vane vacuum pump: the rotary vane vacuum pump mainly includes: 2x rotary vane vacuum pump, 2XZ rotary vane vacuum pump and XZ small rotary vane vacuum pump. 2X type rotary vane vacuum pump is one of the basic equipment used to pump out the gas in the closed container. It can be used alone or as the first several parts of booster pump and molecular pump.

For example, mass spectrometer, vacuum drying oven, vacuum pump refrigerator, etc. Rotary vane vacuum pump can work under any inlet pressure, which has been widely used in food vacuum packaging, plastic industry vacuum molding, printing industry paper transportation, etc.

4. The types and characteristics of liquid ring vacuum pumps are SK liquid ring vacuum pump, direct vacuum pump, 2SK double-stage liquid ring vacuum pump and 2BV stainless steel liquid ring vacuum pump. These pumps are mainly used in the process of coarse vacuum and large air volume. The cast iron vacuum pump is mainly used to pump non corrosive gas. The new stainless steel and glass fiber reinforced plastic materials can transport corrosive gas Body.
