Description
Technical field
The present invention relates to automotive field, specifically refer to a kind of fuel tank protecting oil pump.
Background technology
The function of Fuel supply system is the fuel oil under supplying various operating mode in time to driving engine required for fuel oil, and Fuel supply system is primarily of compositions such as fuel tank, electric oil pump, fuel oil filter, return pipe body, fuel pressure regulator, hydro pulse damper, fuel injector, defeated body, cold-start valvies.Fuel oil is pumped from fuel tank by oil pump, by fuel oil filter elimination impurity, fuel pressure regulator is delivered to through oil pulse damper, under the effect of fuel pressure regulator, make the difference of oil pressure and air inlet pipe internal gas pressure keep constant, then provided and delivered to each fuel injector and cold-start valve by defeated body.Fuel injector, according to the instruction of ECU, controls fuel injection beginning moment and the injection duration of fuel injector, makes fuel injector in time eject required fuel oil.In order to when eliminating oil pump pump oil or fuel injector oil spout time cause oil pressure in pipeline to produce small sample perturbations, in the Fuel supply system of some driving engine, hydro pulse damper is also housed, for the energy in suction line during pressure fluctuation, suppress the pulsation of oil pressure in pipeline with this, improve the oil spout precision of system.
In the fuel feeding stage, fuel oil enters into oil pump through inlet pipe body, and inlet pipe body adopts through type, and without bending, during fuel filling, fuel oil directly enters oil pump by rectilinear direction, and oil pump can be impacted, and can affect its service life.
Summary of the invention
The invention provides a kind of fuel tank protecting oil pump, solve oil pump in fuel tank and be subject to fuel oil and impact and impaired problem, reach protection oil pump, improve the object in fuel tank service life.
Object of the present invention reaches by the following technical programs:
The present invention includes casing and oil pump, oil pump is placed on casing, and described oil feeding device comprises oil guide pipe and oil suction groove, and oil suction groove is arranged at bottom half, the end of oil guide pipe is placed in oil suction groove, the oil inlet of described oil pump is connected with oil suction groove, and described oil guide pipe is circular arc, and described oil guide pipe comprises body and oil outlet, in described oil outlet, spacer is installed, spacer is placed in oil outlet, described spacer has oil outlet and adjustment hole, and oil outlet is to the side flanging near body.Oil suction groove is provided with in casing, the oil inlet of oil pump is placed in oil suction groove, fuel oil flows rapidly in oil suction groove by oil guide pipe, the fuel oil of quick flowing produces larger momentum, certain impact can be produced to the oil inlet place of inboard wall of tube body and oil suction groove and oil pump, under long impact, the oil inlet of inboard wall of tube body particularly oil pump can be first impaired, thus have influence on the normal work of oil pump, and the fuel oil entered in oil suction groove by oil guide pipe can, along oil outlet inwall to surrounding splash, cause the oil outlet of oil guide pipe also easily impaired; The setting of oil feeding device, fuel oil can be changed and directly enter oil pump by oil pipe, body is set to circular arc, fuel flow direction can be changed when carrying fuel oil to enter oil suction groove, the impulsive force of slowing oil in circular arc curve, reduce the impact to oil suction groove and oil pump oil inlet, reach protection oil pump, strengthen the object in its service life;
The spacer installed in oil outlet can play the effect of the buffering quick impact flow oil outlet of fuel oil and oil pump oil inlet, spacer between oil outlet and body can slow down the speed of the fuel oil of flowing fast, fuel oil is made to enter into oil suction groove by oil outlet, prevent fuel oil from entering oil inlet along inboard wall of tube body, reduce splash; Adjustment hole can regulate when amount of fuel is large, a part of fuel oil is flowed out by adjustment hole, plays the effect of pressure release; At the side flanging of oil outlet near body, namely described flange is arrange projection at the edge of oil outlet, slowly shape is at a tilt angle with self inertia to make fuel oil, flow through at fuel oil the oil column formed in oil outlet certain distance to diminish gradually, cannot outwards splash, diffusion, play antispray effect.
Further, described oil outlet radius is 2 ~ 3 times of described adjustment hole radius size.On spacer, when the fuel oil of the overwhelming majority flows to oil suction groove by oil outlet, when amount of fuel is large especially, adjustment hole can share the oil drain quantity of oil outlet, alleviates the impact dynamics at oil outlet place; The radius of oil outlet is set to 2 ~ 3 times of adjustment hole radius, can be applicable to the situation of carrying amount of fuel to vary in size, can effectively prevent fuel oil splash, plays the function of protection oil outlet.
Further, described oil outlet is concentric with spacer.The spacer arranged between body and oil outlet is rounded, and the diameter of oil outlet is concentric with spacer, can make fuel oil quickly through, enter into oil suction groove.
Further, the coating be arranged on spacer and inboard wall of tube body is also comprised.Fuel oil impacts spacer or inboard wall of tube body for a long time, spacer or inboard wall of tube body are easily impaired, spacer or inboard wall of tube body arrange the pressure that coating greatly can increase operational throughput or reduce body conveying, again or the attachment reducing spacer ensures that fuel oil is smooth and easy passes through, economic benefit is increased.
The present invention compared with prior art, there is following advantage and beneficial effect:
1, the present invention includes casing and oil pump, oil pump is placed on casing, and described oil feeding device comprises oil guide pipe and oil suction groove, oil suction groove is arranged at bottom half, the end of oil guide pipe is placed in oil suction groove, and the oil inlet of described oil pump is connected with oil suction groove, and described oil guide pipe is circular arc.The setting of oil feeding device; fuel oil can be changed and directly enter oil pump by oil pipe; body is set to circular arc; fuel flow direction can be changed when carrying fuel oil to enter oil suction groove; the impulsive force of slowing oil in circular arc curve; reduce the impact to oil suction groove and oil pump oil inlet, reach protection oil pump, strengthen the object in its service life.
