The principle of rotary vane vacuum pump, characteristics and applicable scope _

rotary vane vacuum pump is a positive displacement pump, through the gas of the rotary vane continuous operation of the device suction and compressed in the pump chamber, the discharge from the vent. By the stator, rotor, rotary vane pumps, such as eccentric load of stator rotor cavity. There are two rotary vane rotor slot, two rotary vane spring set between rotary vane pumps are described. To the stator, rotor and vent is separated into two parts.

when the rotor on the stator rotating cavity, spring tension and rely on pump room slide cyclical expansion volume of the suction chamber inlet side of the lining of the end itself under the action of centrifugal force of the rotary vane, reduce exhaust volume at the same time, the suction gas is compressed, then exhaust, so as to realize the purpose of the extract from vent.

characteristics and applicable scope

rotary-vane vacuum pump features:

vacuum pump suction a line connected to the coarse filter mesh. In order to prevent solid foreign body dust suction pump chamber. Oil separator installation of oil and gas exhaust transition effects effectively separated. When the pump stops, the inlet valve is built into the pump inlet from pumping system, in order to prevent the oil is pumped back to the system. Through the air pump to cool. XD rotary-vane vacuum pump are all pump driven by motor through flexible coupling orientation.

range of rotary-vane vacuum pump are:

1. The vacuum pump is suitable for use sealing system. Vacuum packaging, vacuum forming, vacuum suction.

2。 Inlet pressure range: pa - 100 100000 Pa, beyond this range will have a pump discharge, to generate oil mist. XD rotary-vane vacuum pump suction gas temperature and environmental temperature should be between 5 ℃ and 40 ℃ ~.

3。 Vacuum is not water or other liquid. is not explosive, flammable, the high oxygen content, corrosive gas.

4。 Motor is not generally available explosion-proof, or other special requirements, such as motor must conform to the requirements of the standards.

working principle of the rotary-vane vacuum pump are

rotary vane vacuum pump is a multi-stage vacuum pump. Rotary vane vacuum pump with single stage and double rotary vane vacuum pump. The so-called double rotary vane vacuum pump, on the structure is in series connection of two single water pump. Two stage more, in order to obtain higher vacuum degree.

rotary vane vacuum pump and the extraction rate of relationship between predetermined inlet pressure is as follows: 1333 pa inlet pressure, in 1. 33 pa and 1. 33×10- 1 ( Pa） , this pump pumping speed of nominal value of no less than 95% pumping speed, 50% and 20%.

double-stage vacuum water pump, made up of two series of single-stage pump. In operation, the gas through the first level into the high vacuum suction pump. When higher suction gas pressure, the expulsion of gas from the discharge valve 2 part of gas through the rest of the low vacuum levels, described in the exhaust valve 1. When the inlet pressure is low, in spite of the high vacuum stage compression, but 2 still did not open the exhaust valve, only very low vacuum to compression, from one discharge exhaust valve, this is because the limit is higher than two stage vacuum pump single-stage water pump

rotary vane vacuum pump application in metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum, medicine production and scientific research departments widely used. It has been widely used in food vacuum packaging, vacuum forming plastic industry. Paper transfer printing industry, vacuum clamp, vacuum suction cups, and so on.
