The working principles of the spiral vacuum pump
1. The working principles of the spiral vacuum pump, which consists mainly of parts such as dots, rotors, rotors, caps, springs, etc. It is constructed to apply the rotor (which is very small between the outer circle of the rotor and the internal and external surface of the rotor) and the two rotor blades, which are slid in the troughs with spring tension and thrust towards the inner wall, and which, when the rotor rotates, are slid along the inner wall of the rotor。
When the rotor rotates in a graphical direction, the volume of space a, which is connected to the inhaler, increases from time to time, the pressure of space a decreases from time to time, when the pressure in space a is lower than that in the pumper, and the gas extracted is pumped into the inhaler a from time to time according to the principle of balancing the pressure of the gas. The volume of b cavity space is gradually decreasing and the pressure is increasing from time to time, at a time of austerity. The volume of space c, which is connected to the vent, is further reduced, the pressure of space c is further increased, when the pressure of the gas is stronger than the pressure of the vent, the gas is pushed out of the exhaust valve, the gas is pumped from time to time through the reservoirs of the tank and is discharged into the atmosphere, and the pump is operated continuously from time to time to stop the inhaling, austerity and exhausting process, thus achieving the objective of continuous pumping。

Emission valves are immersed in oil to avoid atmospheric inflow into the pump, and the oil goes through the gaps in the pump body, the oil hole and the exhaust valve into the pump cavity, covering all movement in the pump cavity with oil, constituting a seal for the inhaler and vent, while the oil fills all harmful spaces in order to mitigate their impact on the limit vacuum。
Spiral vacuum pump maintenance
(1) vacuum pumps shall be kept clean on a regular basis to prevent the entry of miscellaneous items into the pumps

(2) take care of the appropriateness of the loose belt and adjust it every three months
(3) whether the pipeline is leaking and is eliminated in a timely manner。
2. The pump oil shall be replaced with the following steps when the pump pump is purified by the opening of a gas-barrel due to the improper storage or use of water or other volatile substances entering the pump to affect the limit vacuum room and when the pump oil is contaminated by mechanical or chemical impurities:

The pump will be operated for a period of time, the oil will be depleted, the pump will stop, the oil plug will be decentralized, the gas vent will be cleared and open for one minute, during which time a small amount of vacuum pump oil will be slowly added to the vent, the pump core will be washed, the dirty oil will be pumped and tightened, clean vacuum pump oil will be added to the gas vent and a certain amount of vacuum pump oil will be added to the vent。
3. In the case of a longer suspension, rubber plugs, caps and vents should be applied in order not to enter the pump, such as dirty material, so that the water-cooled pump should contain clean water。
