oil free vacuum pump maintenance guide

Oil free vacuum pump is a kind of mechanical vacuum pump which can operate without any oil lubrication. The utility model has the advantages of simple structure, convenient operation, convenient maintenance and no environmental pollution. Oil free vacuum pump is a durable vacuum pump, which is a vacuum pump, compression vacuum, dual-purpose vacuum pump, is the basic equipment to obtain vacuum, and has a wide range of applications. It is a kind of basic equipment which is widely used to obtain vacuum. Compared with the oil pump, the oil-free vacuum pump has the advantages of low vacuum degree, small volume, convenient installation, simple maintenance, convenient movement, no oil fume, no environmental pollution and so on. Oil free vacuum pump mainly includes vane vacuum pump, claw vacuum pump, screw vacuum pump, scroll vacuum pump, piston vacuum pump and so on.

Scroll vacuum pump is one of the most common equipment in the laboratory. Therefore, when purchasing the oil-free vacuum pump, it is necessary to determine the working requirements of the vacuum degree. If the vacuum degree is high, and the vacuum degree is higher than the required vacuum degree, or cannot meet the requirements of the vacuum degree, it cannot meet the working requirements. Secondly, the pumping speed of oil-free vacuum pump will be slightly higher than the required pumping speed in order to better meet the needs.

Finally, to see whether the gas is corrosive or not, and whether the corrosive gas will corrode the pump, special materials must be used to meet the needs. The working principle of the editing pump is the same as that of the general positive displacement pump, which is composed of stator, rotor, rotor, cylinder, motor and other main components. When the rotor rotates at high speed, four radial sliding rotors in the rotor slot divide the pump chamber into four chambers.

Maintenance of oil-free vacuum pump: clean the outside of the shell. Please use a dry and soft cloth to clean the dust and dirt on the outside of the shell at least once a month when the power supply is cut off. It is very important to clean the intake filter silencer and filter cotton of the filter silencer, which directly affects the flow and service life of the vacuum pump. Clean it at least once a month. Please screw off the silencer, dismantle the end cover of the silencer, take out the filter cotton, wash it with clean water, cool and dry, and then install it for use. If it cannot be cleaned, replace the filter cotton.

Oil free vacuum pump is suitable for high pressure and small flow, especially when the flow is less than 100m3 / h and the discharge pressure is more than 9.8MPa, it shows its high efficiency and good performance. It has good suction performance. It can pump liquid with different medium and viscosity. Therefore, it is widely used in petrochemical industry, machinery manufacturing industry, papermaking, food processing, pharmaceutical production, etc.
