Detailed description of the invention

Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not It is limited only to embodiment.

Shown in Fig. 1-Fig. 4, a kind of electronic oil pump, there is the pump housing 2, the side of the pump housing 2 is provided with electricity Machine 1, has been arranged side by side oil sucting cavity 22 and pressure oil cavity 21 in the pump housing 2, be additionally provided with and nibble mutually in the pump housing 2 Closing the driving gear 6 and driven gear 7 connected, the center between driving gear 6 and driven gear 7 connects Central junction line L2 between line L1 and oil sucting cavity and pressure oil cavity is orthogonal, L1 and L2 hangs down mutually Directly divide equally.Driving gear 6 bottom left portion structure is placed in pressure oil cavity 21, driving gear 6 bottom Right part structure is placed in oil sucting cavity 22；The upper left hand portion structure of driven gear 7 is placed in pressure oil Chamber 21 is interior, the upper right part-structure of driven gear 7 is placed in oil sucting cavity 22.Driving gear 6 and quilt The engagement place of moving gear 7 between oil sucting cavity 22 and pressure oil cavity 21, and engagement place be positioned at L1 and The intersection of L2.The entrance 13 and and pressure oil connected with described oil sucting cavity 22 it is additionally provided with on the pump housing 2 The outlet 12 of chamber 21 connection.

Motor 1 is connected with described driving gear 6, is provided with trig loop 4 between motor 1 and driving gear 6, Motor 1 is provided with hub splines 3 outside the junction of driving gear 6, is additionally provided with solid outside driving gear 6 The leather cup combination 5 determined.The side of the pump housing is provided with pump cover, is provided with packing ring 8 between pump cover and the pump housing.

It is provided with cooling water cavity in the pump housing, outside the pump housing, is provided with the cooling water pipe 10 connected with described cooling water cavity, One end of cooling water pipe 10 is provided with swivel joint assembly 11, from pressure inlet and rotation by screw chuck 9 Tube adapter assembly 11 is intake, it is ensured that water circulating cooling, screw chuck 9 and swivel joint assembly 11 it Between be provided with copper folder asbestos washer 18.

Also include that safety control system, described safety control system include oil return valve body 17, pressure regulating valve Spring 16, steel ball 19 and drainback passage 23, in described drainback passage 23 is located at the pump housing 2 and two ends Communicating respectively at entrance 13 and outlet 12, what steel ball 19 was located at drainback passage 23 and entrance 13 communicates place, Oil return valve body 17 is located at the side of the pump housing 2, one end of pressure regulating valve spring 16 and oil return valve body 17 connections, the other end are connected with steel ball 19.Set between pressure regulating valve spring 16 and oil return valve body 17 There is adjustment packing ring 15, between oil return valve body 17 and the pump housing 2, be provided with copper folder asbestos washer 18.Normal work When making, steel ball 19 gets lodged in drainback passage 23 and porch；During special circumstances, regulate oil return valve body 17, Being opened under making steel ball 19 about elastic force, entrance and exit is directly communicated by drainback passage, can play Draining effect.Regulation oil return valve body 17, it is ensured that open when P=1.2 ± 0.2MPa.

Operation principle is as follows: presses shown by arrow direction when the driving gear 6 of the pump housing 2 and makees counterclockwise to rotate Time, driving gear and driven gear at oil sucting cavity 22 be disengaged, and the gear teeth of gear exit former engagement Between cog, makes the sealed volume of between cog increase, and forms parital vacuum, and the fluid in fuel tank is at the work of atmospheric pressure Under with, through inlet line. oil sucting cavity enters between cog；Along with driving gear and the rotation of driven gear, suck The fluid of between cog is brought to opposite side, enters the pressure oil cavity 21. at this moment gear teeth and enters engagement, makes the close of between cog Envelope volume is gradually reduced, and the fluid of between cog part is extruded, and pump i.e. realizes oil extraction.When driving gear is by electronic Machine drives when rotating continuously, and in oil sucting cavity side, the gear teeth are disengaged in succession, and sealed volume constantly becomes big, Then oil suction from fuel tank continuously；In pressure oil cavity side, owing to the gear teeth subsequently enter engagement, sealed volume is not Disconnected reduction, the most continuously to system fuel feeding.When system pressure exceedes the pressure of relief valve, open steel ball and unload Lotus.

Last it is noted that above example only in order to this utility model is described and and unrestricted practicality new Technical scheme described by type, therefore, although this specification is new to this practicality with reference to each above-mentioned embodiment Type has been carried out detailed description, but, it will be understood by those within the art that, still can be right This utility model is modified or equivalent, and all are without departing from the skill of spirit and scope of the present utility model Art scheme and improvement thereof, it all should be contained in right of the present utility model.
