Industrial vacuum pump classification

A machine that sucks gas out of a device so that the pressure in the device is lower than an atmospheric pressure is called a vacuum pump. In fact, the vacuum pump is a kind of gas conveying machinery, it carries gas from the environment below an atmospheric pressure to the atmosphere or the same atmospheric pressure environment.


Vacuum pump is often used in chemical production to create a certain degree of vacuum to achieve process operation. For example, under the suction of a vacuum pump, the filtration rate of the solution is accelerated; when the liquid mixture is separated, the distillation temperature can be lowered to avoid the coking and decomposition phenomena that may occur in high temperature distillation; the temperature of the dry solid material is reduced and the speed is accelerated; the heat pipe of a heat exchanger is pumped into a vacuum and then injected into distilled water. The heat transfer rate is greatly accelerated. The electronics industry and the defense industry often need a higher vacuum.

Generally speaking, vacuum pumps are divided into three categories, namely water-filled vacuum pumps, refueling vacuum pumps and oil-free vacuum pumps.


1. The water-filled vacuum pump refers to the water-ring vacuum pump, which uses water as working fluid to achieve suction, compression and exhaust by changing the volume of the pump chamber, so as to achieve the purpose of extracting vacuum. The pump can extract gases containing water vapor and corrosiveness. Its type is 2BV water-ring vacuum pump, 2BE water-ring vacuum pump, 2SK water-ring vacuum pump and SK water-ring vacuum pump.


2. Refueling vacuum pump refers to rotary vane vacuum pump. The gap between rotary vane and pump cavity is sealed by oil. The vacuum degree is much higher than that of water ring vacuum pump, but water vapor and corrosive gas can not be pumped. The main types of vacuum pump are 2XZ rotary vane vacuum pump, 2X rotary vane vacuum pump, XD rotary vane vacuum pump, X-X rotary vane vacuum pump. Single stage rotary vane pump and ZJ type roots vacuum pump.


3. Oil-free vacuum pump is often used in clean environment, will not pollute the products produced, the main model of oil-free vacuum pump.
