Performance of oil free vacuum pump

The working principle of oil-free vacuum pump is the same as that of general positive displacement pump. It is composed of stator, rotor, rotating plate, cylinder block, motor and other main parts. The rotor with rotating blades is eccentrically installed in the stator cylinder. When the rotor rotates at high speed, the four radial sliding blades in the rotor slot divide the pump chamber into four working rooms. Due to the centrifugal force, the rotating blades are close to the cylinder wall, separating the stator inlet and outlet. The operation is repeated to change the volume and discharge the inhaled gas from the exhaust port, so as to achieve the purpose of air extraction. 

At present, there are few domestic oil-free vacuum pump manufacturers. Basically, they can only produce rotary vane vacuum pump products that must be filled with vacuum oil. Basically, the market is imported oil-free vacuum pump products. It has the advantages of simple structure, easy operation, convenient maintenance and no pollution to the environment. The two series of oil-free vacuum pumps have good durability. They are vacuum pumping, compression and dual-purpose vacuum pumps. They are basic equipment with a wide range of applications to obtain vacuum.

The oil-free vacuum pump has the advantages of convenient maintenance, easy operation, simple structure and no environmental pollution. The oil-free vacuum pump has good durability. It is a vacuum pump, compression and dual-purpose vacuum pump. It is a basic equipment with a wide range of applications to obtain vacuum. Compared with oil pump, oil-free vacuum pump has low vacuum degree and small pumping capacity, but it is small in size, easy to install, easy to maintain, convenient to move, no oil fume and no pollution to the environment, especially in the laboratory with high requirements. It is also one of the most common equipment in the laboratory. Therefore, when purchasing the oil-free vacuum pump, the vacuum degree required to work must be determined first. If the vacuum degree required is high, the vacuum pump selected shall be higher than the vacuum degree required, otherwise, the vacuum pump cannot meet the requirements of vacuum pumping, and the working requirements will not be met. Secondly, the pumping rate of oil-free vacuum pump should be slightly greater than the required pumping rate, so as to better meet the needs. Finally, see whether the extracted gas is corrosive. Corrosive gas will corrode the pump. Special materials must be used to meet the demand
