Problems solved by technology

[0002] The oil and gas recovery function of the oil and gas recovery system of the gas station is one of its necessary functions. If the return air of the fuel gun fails or does not meet the standard, it is easy to cause the fuel gun to jump in advance or affect the normal adjustment or other fueling failures when refueling. Therefore, the air return function of the refueling gun is usually tested during regular inspections, and the air return function of the refueling gun in the oil vapor recovery system of the gas station is mainly controlled by the oil vapor recovery pump installed in the fue

Embodiment 1

[0060] Such as Figure 1 to Figure 11 As shown in one of them, the present invention has a vacuum pump with early warning of performance degradation, including:

[0061] The casing 1 is a cylindrical shell structure with one end open;

[0062] The motor 2 is fixed in the casing 1, and its driving end has a rotating shaft 21 and the rotating shaft 21 extends along the open end of the casing 1;

[0063] Crankshaft 22, one end is a straight end and the end is fixedly connected with the rotating shaft 21 of the motor 2, and the other end is an eccentric end;

[0064] Fan blades 23 are even-numbered and fixedly connected to the straight end of the crankshaft 22 in a circular array;

[0065] The sub-housing 12 is fixed on the open end of the casing 1 and encapsulates the fan blade 23 and the motor 2 in the casing 1. The sub-housing 12 is provided with an avoidance through hole for the other end of the crankshaft 22 to pass through;

[0066] The negative pressure housing 3 is a cy...

Embodiment 2

[0084] Such as Figure 1 to Figure 15As shown in one, this embodiment is based on the structure of the vacuum pump with performance attenuation early warning in the above-mentioned embodiment 1. This embodiment also provides an early warning and troubleshooting device for oil and gas recovery vacuum pumps, which is installed in the refueling system. The refueling system Including oil tank 9, fuel dispenser 8, refueling gun 6, transmission pipeline 7 (including oil delivery pipe 71 and oil vapor recovery pipe 72); said oil tank 9 is sequentially connected with fuel dispenser and refueling gun through oil delivery pipe 71, said The oil vapor recovery pipe 72 is arranged in parallel with the oil delivery pipe 71 and the oil vapor recovery pipe 72 is connected with the refueling gun, the refueling machine and the oil tank 9 in sequence and is used to recover the oil and gas overflowed when the refueling gun is refueled. This embodiment includes the above-mentioned performance atten...

Abstract

The invention discloses a vacuum pump with the function of performance degradation early warning and application of the vacuum pump to an oiling machine. The vacuum pump comprises a machine shell, a motor, a crankshaft, fan blades, an auxiliary shell, a negative-pressure shell and a crank piston. One end of the crankshaft is a straight end and is fixedly connected with a rotating shaft of the motor. The fan blades are fixedly connected to the straight end of the crankshaft. The auxiliary shell is fixed to the open end of the machine shell and packages the fan blades and the motor in the machine shell. The negative-pressure shell is of a barrel-shaped shell structure with one end being open and is fixed to the side, penetrating out of the crankshaft, of the auxiliary shell. The piston end of the crank piston adapts to the open end of the negative-pressure shell, penetrates into the negative-pressure shell from the open end of the negative-pressure shell and is in sliding connection in the negative-pressure shell, the crank end of the crank piston is connected with the eccentric end of the crankshaft, and the rotating shaft of the motor rotates to drive the crankshaft to drive the crank end of the crank piston to draw the piston end of the crank piston to do piston motion in the negative-pressure shell. The vacuum pump further comprises a first negative pressure sensing mechanismconnected to the auxiliary shell of the vacuum pump, performance early warning of the vacuum pump is carried out through the negative pressure sensing mechanism, and implementation of the scheme is reliable.

Description

technical field [0001] The invention relates to the field of fuel dispenser systems, in particular to a vacuum pump with performance attenuation warning and its application in fuel dispensers. Background technique [0002] The oil and gas recovery function of the oil and gas recovery system of the gas station is one of its necessary functions. If the return air of the fuel gun fails or does not meet the standard, it is easy to cause the fuel gun to jump ahead of time or affect the normal adjustment or other fueling failures when refueling. Therefore, the air return function of the refueling gun is usually tested during regular inspections, and the air return function of the refueling gun in the oil vapor recovery system of the gas station is mainly controlled by the oil vapor recovery pump installed in the fuel dispenser. As we all know, the vacuum pump After long-term work, there will be a certain degree of power attenuation or other problems that cause its negative pressur...
