2X Rotary Vane Vacuum Pump


2X rotary vane vacuum pump is the basic equipment used to extract the gases from a special sealed container and make it obtain a certain vacuum. Due to the high development of modern science and technology, vacuum pump is widely used in various scientific fields and various enterprises and institutions. It can be used in metallurgy, chemical industry, light industry, petroleum, medical treatment, pharmacy, printing and dyeing. Electrical appliances, electric vacuum, semiconductor, food, atomic energy, textile and other scientific research institutions, colleges and universities, industrial and mining enterprises for scientific research and production and teaching purposes.

Because the rotary vane vacuum pump is made of ferrous metal, and more precise, the work of the whole pump is linked together, so rotary vane vacuum pump is not suitable for the removal of excessive oxygen, toxic, explosive corrosion of ferrous metals and the chemical role of various gases in the vacuum oil, nor can it be used as a compressor. And transport pumps.


2X rotary vane vacuum pump pumping process:

Gas enters the high vacuum chamber from the air inlet nozzle, initially high pressure, high and low vacuum chambers are full of atmosphere, both exhaust valves open exhaust. As the exhaust proceeds, the pressure decreases (i.e. the vacuum increases), the pressure in the high vacuum chamber is insufficient to push the exhaust valve open, and the gas enters the low vacuum chamber through the diaphragm. At this time, the pressure is insufficient to push the exhaust valve open, but the low vacuum chamber enters with a certain amount of oil to help push the exhaust valve open, and the gas is also discharged. Oil particles mixed with the exhaust gas are filtered through the oil screen to separate the oil. Only the gas is discharged out of the pump and the gas path is through.
