In response to the common problems of poor stability in the use of vacuum pumps in the sec-ondary oil vapor recovery system of gas stations,such as drift of gas-liquid ratio,lower service life than ex-pected,and high maintenance costs,which have ad-verse effects on the management and operation of gas stations,by improving the structure of the type of vac-uum pump,the operational stability of the pump has been effectively improved,the service life of the pump has been extended,the maintenance cost of the pump has been reduced,and the environmental management level of the gas station has been improved.
