Description
Technical field
The utility model relates to fuel delivery equipment, specifically refers to a kind of oil feeding device.
Background technique
The function of fuel oil supply system is to supply in time the needed fuel oil of fuel oil under various operating modes to motor, and fuel oil supply system is mainly comprised of fuel tank, electric fuel punp, fuel filter, return tube, fuel pressure regulator, hydro pulse damper, oil sprayer, transport pipe, cold-start injector etc.Fuel oil is pumped from fuel tank by fuel pump, by fuel filter elimination impurity, through oil pulse damper, deliver to fuel pressure regulator, under the effect of fuel pressure regulator, make the difference of oil pressure and suction tude internal air pressure keep constant, then by transport pipe, provided and delivered to each oil sprayer and cold-start injector.Oil sprayer, according to the instruction of ECU, is controlled the fuel injection beginning moment and the injection duration of oil sprayer, makes oil sprayer in time eject required fuel oil.Cause that the oil pressure in pipeline produces small sample perturbations when eliminating fuel pump when oil or oil sprayer oil spout, hydro pulse damper is also housed in the fuel oil supply system of some motor, energy during for suction line pressure fluctuation, with this, suppress the pulsation of oil pressure in pipeline, improve the oil spout precision of system.
In the fuel feeding stage, fuel oil enters into fuel pump through oil inlet pipe, and oil inlet pipe adopts straight-through type, without crooked, during fuel filling, fuel oil directly enters in oil suction groove by rectilinear direction, and it is produced and is impacted, fuel pump, also in oil suction groove, equally also can be impacted simultaneously, can affect its working life.
Model utility content
The utility model provides a kind of oil feeding device, solves oil pump and is subject to the problem that fuel oil impacts, and reaches protection oil pump, improves the oil pump object in working life.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises oil guide pipe and oil suction groove, the end of described oil guide pipe is placed in oil suction groove, described oil guide pipe comprises oil pipe and oil outlet, in described oil outlet, spacer is installed, spacer is placed in the joint of oil outlet and oil pipe, on described spacer, have oil outlet and adjustment hole, oil outlet is to the side flanging near oil pipe, and described oil pipe is circular arc.In fuel tank, be provided with oil suction groove, the filler opening of fuel pump is placed in oil suction groove, fuel oil flows in oil suction groove fast by oil guide pipe, the fuel oil of rapid flow produces larger momentum, can produce certain impact to the filler opening place of tube inner wall and oil suction groove and fuel pump, under impacting for a long time, particularly the filler opening of fuel pump can be first impaired for tube inner wall, thereby have influence on the normal operation of fuel pump, and the fuel oil being 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 spacer of installing in oil outlet can play the effect that buffering fuel oil rapid flow impacts oil outlet and fuel pump filler opening, spacer between oil outlet and oil pipe can slow down the speed of the fuel oil of rapid flow, make fuel oil enter into oil suction groove by oil outlet, prevent that fuel oil from entering filler opening along tube inner wall, reduce splash; Adjustment hole can regulate when amount of fuel is large, and a part of fuel oil is flowed out by adjustment hole, plays the effect of pressure release; A side flanging at oil outlet near oil pipe, so-called flange arranges flange at the edge of oil outlet, slowly shape is at a tilt angle with self inertia to make fuel oil, the oil column forming in fuel oil flows through oil outlet certain distance diminishes gradually, outwards splash, diffusion, play antispray effect; Oil pipe is set to circular arc; when entering oil suction groove, delivering fuel can change fuel flow direction; the impact force of slowing oil in circular arc curve, reduces the impact to oil suction groove and fuel pump filler opening, reaches protection fuel pump, strengthens the object in its working life.
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 be shared the oil drain quantity of oil outlet, alleviates the impact dynamics at oil outlet place; The radius of oil outlet is made as 2～3 times of adjustment hole radius, can be applicable to the situation that delivering fuel amount varies in size, and can effectively prevent fuel oil splash, plays the function of protection oil outlet.
Further, described oil outlet is concentric with spacer.The spacer arranging between oil pipe and oil outlet is rounded, and the diameter of oil outlet is concentric with spacer, can make fuel oil pass through fast, enters into oil suction groove.
Further, also comprise the coating being arranged on spacer and tube inner wall.Fuel oil is for a long time to spacer or tube inner wall impacts, spacer or tube inner wall are easily impaired, coating is set on spacer or tube inner wall can greatly be increased quantity delivered or reduce the pressure that oil pipe is carried, again or the attachment that reduces spacer guarantee that fuel oil is smooth and easy and pass through, increase economic benefit.
Further, as preferably, described coating is the mixture of solvent-free modified epoxy and ceramic fine bead and the mixture of ceramic fine bead.Solvent-free modified epoxy is as the film forming matter of coating, with ceramic fine bead, carry out filler, can effectively improve the anti-adhesion of coating, improve tube inner wall surface finishment high, reduce transporting resistance, and in filler, contain ultraviolet light absorber, improved the weatherability of coating, extended the working life of coating.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises oil guide pipe and oil suction groove, the end of described oil guide pipe is placed in oil suction groove, described oil guide pipe comprises oil pipe and oil outlet, in described oil outlet, spacer is installed, spacer is placed in the joint of oil outlet and oil pipe, on described spacer, have oil outlet and adjustment hole, oil outlet is to the side flanging near oil pipe, and described oil pipe is circular arc.A side flanging at oil outlet near oil pipe, make fuel oil with self inertia slowly shape at a tilt angle, the oil column forming in fuel oil flows through oil outlet certain distance diminishes gradually, outwards splash, diffusion, strengthen antispray effect.
2, the spacer that the utility model arranges between oil pipe and oil outlet is rounded, and the diameter of oil outlet is concentric with spacer, can make fuel oil pass through fast, enters into oil suction groove.
