Description
Technical field
The present invention relates to oil pump technology field, especially a kind of stabilized structure type oil pump.
Background technology
Oil pump is applicable to carry various oils, such as gasoline, diesel oil, lubricating oil etc., oil pump enter oil discharge passage
It is normally at the bottom of oil pump, in order to consider the heat dispersion of oil pump, the wall bottom oil pump and between its inner chamber
Thick relatively thin, thus cause the wall thickness into oil discharge passage relatively thin, in actual use due to the existence of vibration,
The oil discharge passage that enters causing oil pump easily cracks, thus causes oil pump leakage of oil.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the wall thickness of the oil inlet and outlet of oil pump in prior art
The relatively thin problem easily cracked, a kind of stabilized structure type oil pump of existing offer, this oil pump structure is compact, body
Long-pending little, lightweight, consumptive material is few and it is high to enter the intensity of oil discharge passage.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stabilized structure type oil pump, including
Having an oil pump body of inner chamber and pump cover that lid is located on oil pump body, the bottom of described oil pump body is provided with
Strip projected parts outwardly, the two ends of described strip projected parts offer fuel feed hole and oil outlet respectively inwards.
By arranging strip projected parts outwardly in the bottom of oil pump body in this programme, at strip projected parts
Inward at both ends offers fuel feed hole and oil outlet, while not extending pump housing integral thickness, adds fuel feed hole
With the wall thickness of oil outlet, it is effectively prevented fuel feed hole and oil outlet cracking, owing to the bottom of oil pump body needs
Want milling face, in order to the steady installation of oil pump, extend the design of strip projected parts in oil pump bottom, moreover it is possible to reduce milling
Face area, reduces processing cost, now has only to machine the bottom surface of strip projected parts；It is known that it is oily
When pump own temperature is too high, its internal sealing ring easily lost efficacy, and caused oil pump to leak, strip projected parts
Design can also increase the contact area with air so that the heat on oil pump body is dispersed into rapidly in air,
So that oil pump body has preferable heat dispersion.
In order to reduce the weight of oil pump body and increase the heat dispersion of oil pump body, further, described oil
The bottom surface of pump body has the depressed part caved inward, when the design of depressed part can reduce oil pump body molding
Consumptive material, thus alleviate the weight of oil pump.
Owing to offering of depressed part may result in the intensity of strip projected parts and be affected, further, described
Being provided with some reinforcements in depressed part, reinforcement, while improving strip projected parts steadiness, improves oil
The heat dispersion of pump body.
Preferably, described reinforcement one end is fixing with described oil pump body to be connected, and the other end is convex with described strip
Play fixing connection.
Preferably, the cross section of described strip bulge is square.
Preferably, the two ends of described strip projected parts lower surface are all outward extended with protuberance, can reduce oil
The machining of pump body, only need to be to the milling face, bottom surface of protuberance.
For the ease of being tightly connected into and out of oil pipe and fuel feed hole and oil outlet, further, described strip
Protruding two ends end face is plane.
Preferably, the outer surface of described pump cover has some grooves for heat radiation.
For the ease of improving oil pump lift, the inner chamber of described oil pump body is provided with oil-in and oil-out,
Described oil-in connects with fuel feed hole, and described oil-out connects with oil outlet, and the area of described oil-in is more than
The area of oil-out, the area of oil-in is more than the area of oil-out, so that during operation of oil pump, fuel-displaced
The pressure of mouth is relatively big, can effectively improve this oil pump lift.
The invention has the beneficial effects as follows: the stabilized structure type oil pump of the present invention by arranging strip projected parts, and
The design of fuel feed hole and oil outlet is offered at the two ends of strip projected parts respectively, adds the wall of fuel feed hole and oil outlet
Thickness, is effectively prevented fuel feed hole and oil outlet ftractures, and improves the heat dispersion of oil pump body, reaches
The effect that compact conformation, volume are little, lightweight, low cost, smooth running, noise are little and the life-span is high.
