Distributed automatic-compensation vane vacuum pump

Abstract

The invention discloses a distributed automatic-compensation vane vacuum pump. The vane vacuum pump comprises a rotor (2), wherein a plurality of vane grooves are arranged in the rotor (2), and one vane (3) is placed in each vane groove; a vane magnet (4) is inlaid in one end part of each vane (3), an embedded magnet (5) is arranged in each vane groove, and the like poles of the embedded magnet (5) and the vane magnet (4) are oppositely arranged; compensation gaskets (7) are installed at combined surfaces of the two ends of the rotor (2) and a pump body (11) respectively; check valves (16) are further arranged in the vacuum pump, and an inlet end of the check valve (16) communicates with a gas outlet (1). Strong magnets are inlaid in the vanes and the rotor in the vane vacuum pump, and wear of the vanes can be automatically compensated during a use process by virtue of the principle of 'like poles repel, and unlike poles attract' of the magnets, thus the service life is prolonged; and check valves are arranged at an inlet and an outlet in the vane vacuum pump respectively, and capable of ensuring constant outlet pressure and vacuum degree of the vacuum pump, thus recovery and use for oil and gas are met.

Description

Technical field [0001] The invention belongs to the technical field of vacuum pumps, and in particular relates to a decentralized automatic compensating vane vacuum pump suitable for the extraction and delivery of volatilized gasoline gas for secondary oil and gas recovery in gas stations. Background technique [0002] Commonly used vane pumps are not resistant to wear during use. After a period of use, the worn powder blocks the outlet of the vacuum pump under pressure, which has a serious impact on the secondary oil and gas recovery system. In addition, the blades cannot be used continuously after being worn and must be replaced, which shortens the service cycle, increases the cost of the maintenance of the gas station in the later stage of the gas recovery, wastes manpower and material resources, and causes unnecessary economic losses. In order to solve this problem, the inventor designed a decentralized automatic compensation vane vacuum pump suitable for the extraction and d...

AI Technical Summary

Problems solved by technology

[0002] Commonly used vane pumps are not resistant to wear during use, and after a period of use, the worn powder blocks the outlet of the vacuum pump under the action of pressure, which has a serious impact on the secondary oil and gas recovery system.

Moreover, the blades cannot continue to be used after wear and tear, and must be replaced, which shortens the service cycle, increases the cost of maintenance in the later stage of oil and gas recovery at the gas station, wastes manpower and material resources, and causes unnecessary economic losses
