Abstract
The utility model relates to an oil-gas recovery pump. The pump comprises a motor and a pump body, wherein the casing of the motor is connected with the pump body fixedly, the pump is a vane pump, a rotor of the vane pump is connected with the output end of a motor shaft fixedly, a plurality of vanes are provided and installed inside the circumference of the rotor, the vanes are cylindrical, a cylinder made of a magnetic material is coated by an elastic layer to form the cylinder, the rotor is made of a stainless steel material, cylindrical grooves which are in movable fit with cylinders are formed in the circumference uniformly, and outward repulsive force exists among the cylinders, so that outer circular surfaces of the cylinders is in close contact with inner rings of the pump body. The oil-gas recovery pump has the advantages that the sealing performance is reliable, the service life is long, and the pump is suitable for a gas station.
Description
Technical field
The utility model relates to a kind of gasoline pump, particularly about a kind of pump with oil gas recovery function.The oil gas that the utility model is applicable to the gas station reclaims pump.
Background technique
Oil gas reclaims pump and is used for gas station's oil transportation process to the recovery of oil gas, oil gas is dispersed into befouling environment and energy loss in the air when avoiding oil transportation, its structure generally comprises motor and pump, vane pump is that oil gas reclaims the more general a kind of structure of pump, when work blade contacted with sealing between the pump housing internal chamber wall by the spring compression in the rotor, its major defect is fatiguability after the long-term use of spring, elastic force reduces or damages, make sealability decline between blade and the pump housing internal chamber wall, even cisco unity malfunction, particularly during low speed rotation, the sealability between blade and the pump housing internal chamber wall can obviously descend poor sealing performance, working life is short.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, provides that a kind of sealability is reliable, the oil gas of long service life reclaims pump.
The technical solution of the utility model comprises motor and pump, the housing of motor is fixedly connected with the pump housing, pump is vane pump, the rotor of vane pump is fixedly connected with the motor shaft output terminal, and blade has several, evenly is installed in the rotor circumference, mainly be that blade is cylindrical structure, this cylindrical body is comprised of the cylinder outer wrapping plastic layer of magnetic material, and rotor adopts stainless steel material, and even circumferential is shaped with and cylindrical body cylinder groove movingly.
In above technological scheme, the quantity of blade adopts four or more.
The beneficial effects of the utility model are cylindrical bodys that blade adopts in-built magnetic material, produce mutually outside repulsive force between each cylindrical body, make the interior ring close contact of each cylindrical body periphery and the pump housing, and sealability is reliable, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation between A-A direction pump rotor, blade and the interior ring among the utility model Fig. 1.
Embodiment
Oil gas as shown in Figure 1 reclaims pump, comprise motor 2 and pump, the housing 4 of motor 2 is fixedly connected with the pump housing 6, pump is vane pump, the rotor 11 of vane pump is fixedly connected with motor shaft 12 output terminals, blade has several, evenly be installed in rotor 11 circumference, blade is cylindrical structure, this cylindrical body is comprised of the cylinder 7 outer wrapping plastic layers 3 of magnetic material, and rotor 11 adopts stainless steel material, and even circumferential is shaped with and cylindrical body cylinder groove movingly, cylindrical body can radially move freely in cylinder groove, as shown in Figure 2.The cylinder 7 of each magnetic material adopts same sex materials, makes to produce mutual repulsive force between each cylindrical body, and this repulsive force promotes interior ring 5 close contacts of each cylindrical body and pump, reliable sealing between the interior ring 5 of maintenance cylindrical body and pump, and be not subjected to the impact of rotating speed.The quantity of blade adopts four or more, adopts in the present embodiment five blades.Housing 4 outsides of motor 2 are provided with protective housing 1, and the pump housing 6 is fixedly connected with joint 8, joint 8 interior installation filters 10, and joint 8 is connected with the oil gas recovery channel by pipe joint 9.The rotating speed of motor 2 passes through the computer auto-adjustment control by the flow of oil, automatically regulates the rotating speed control gettering quantity of pump, and Precise Control of Oil gas reclaims ratio.
Claims (2)
