Technical field
The present invention relates to engine water pump technical field, more particularly, to a kind of engine water pump exhaust inlet and its processing side
Method.
Background technology
Engine drives water pump bearing and wheel rotation by belt pulley, and the coolant in water pump is driven by impeller revolves together
Turn, be inhaled under unit fixed on water pump suction and the differential pressure action of impeller center through water pipe in impeller, realize the reciprocation cycle of coolant.
The bearing grease lubrication of pump shaft is supported, therefore to prevent coolant from leaking into lubricating grease and causing lubricating grease newborn
Change, while also to prevent the leakage of coolant.There is exhaust outlet on water pump cover, between water seal and bearing, to offset water
Pressure differential caused by pump shaft high speed rotation.Meanwhile once there is coolant to leak through water seal, it can be released from exhaust outlet, it is cold to prevent
But liquid enters bearing bore, and destroys bearing lubrication and component corrosion.
As shown in Fig. 2, the design of water pump exhaust outlet at present is usually directly to bore single straight hole in water pump cover, it is directly communicated to
Space between water seal and bearing.Since engine often carries out under conditions of relatively badly, the process of operation is often adjoint
The particulate matters such as silt.Entered there are sand grain by water pump exhaust outlet inside water pump and cause water pump bearing serious wear even
There is stuck risk.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention be to provide a kind of engine water pump exhaust inlet and
Its processing method, enters water pump inner cavity probability to achieve the purpose that effectively to reduce foreign matter.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of engine water pump exhaust inlet, the exhaust outlet are arranged in engine water pump case, on the water pump cover
Boss is equipped with by water pump pulley side, the exhaust outlet includes two sections to be connected, respectively outer exhaust outlet and interior exhaust outlet, institute
State outer exhaust outlet to be arranged in boss, interior exhaust outlet is tilted and is located in water pump cover.
Wherein, the boss is cylinder boss.
The center line of the outer exhaust outlet is parallel with water pump rotating shaft center line.
The internal diameter of the outer exhaust outlet is more than the internal diameter of interior exhaust outlet.
The outer exhaust outlet has distance with interior exhaust outlet connecting place to the bottom of outer exhaust outlet.
The distance between the outer end face of the outer exhaust outlet and water pump composition surface are 25-35mm.
Angle between the axis of the interior exhaust outlet and water pump composition surface is 25 ° -35 °.
The external port edge of the outer exhaust outlet is equipped with convex-concave structure.
The boss and water pump cover are structure as a whole.
A kind of processing method of engine water pump exhaust inlet, comprises the following steps：
1) on water pump cover boss is added by water pump pulley side；
2) the processing outer exhaust outlet parallel with water pump rotating shaft center line on boss；
3) the inclined interior exhaust outlet being connected with outer exhaust outlet is processed in water pump cover, interior exhaust outlet corresponds to water pump shell
Position between body water seal and bearing.
Compared with prior art, the present invention has the following advantages：
Engine water pump exhaust outlet structure design is reasonable, has increased the outlet port of water pump exhaust outlet by boss, by
It is water pump pulley in top, reduces possibility of the foreign matter by outer exhaust outlet intake pump；The exhaust outlet of inside and outside two sections of designs
The probability that foreign matter enters water pump inner cavity can effectively be reduced；The angle and diameter design of the interior exhaust outlet of water pump inner cavity connector are closed
Reason, makes water pump be easier to ventilate with outside.

Face.
Embodiment
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Explanation.
As shown in Figure 1, the engine water pump exhaust inlet is arranged in engine water pump case, water pump is leaned on water pump cover 1
Pulley side is equipped with the boss 2 of cylinder, and exhaust outlet includes two sections to be connected, respectively outer exhaust outlet 3 and interior exhaust outlet 4, outside
Exhaust outlet 3 is arranged in boss 2, and interior exhaust outlet 4 is tilted and is located in water pump cover 1.
The outlet port of water pump exhaust outlet is increased by boss 2, since top is water pump pulley, has reduced foreign matter and lead to
Cross the possibility of outer exhaust outlet intake pump；The exhaust outlet of inside and outside two sections of designs also can effectively reduce foreign matter into the several of water pump inner cavity
Rate.
The internal diameter of outer exhaust outlet 3 is more than the internal diameter of interior exhaust outlet 4, and the diameter of outer exhaust outlet is more than the diameter of interior exhaust outlet,
Be conducive to the ventilation of water pump.
The distance between the outer end face of outer exhaust outlet 3 and water pump composition surface 6 are 25-35mm.The axis and water of interior exhaust outlet
The angle pumped between composition surface is 25 ° -35 °.Boss and water pump cover are structure as a whole.The center line and water pump of outer exhaust outlet 3
Rotating shaft center's line 5 is parallel.Outer exhaust outlet has distance with interior exhaust outlet connecting place to the bottom of outer exhaust outlet.In this way, such as
Outside has silt to have to pass through outer exhaust outlet, interior exhaust outlet and angle existing for outer exhaust outlet first into water pump, can be mud
Sediment barrier is in outer exhaust outlet.
The external port edge of outer exhaust outlet 3 is equipped with convex-concave structure, prevents sheet foreign matter from covering in the external port of outer exhaust outlet,
The setting of convex-concave structure can ensure ventilatory effect.
The processing method of specific engine water pump exhaust inlet：
The increased cylinder boss on water pump cover, processes the outer exhaust outlet of φ 7mm on boss cylinder.Outer exhaust outlet with
Height of the aperture position of air contact apart from water pump composition surface is 30mm, can effectively reduce silt and contact opening for outer exhaust outlet
Mouthful, reduce the probability that particulate matter enters water pump.The diameter that an angle is 30 ° is made a call in position between water pump cover water seal and bearing
It is connected for the interior exhaust outlet of φ 4mm with the outer exhaust outlet of φ 7mm on water pump cover.Interior exhaust outlet is connected with outer exhaust outlet, so
Water pump interior air-flow is just ventilated by inside and outside two sections of exhaust outlets with extraneous.Interior exhaust outlet and outer exhaust outlet, can there are 150 ° of angle
Silt is kept off in outer exhaust outlet.Meanwhile the diameter of outer exhaust outlet is more than the diameter of interior exhaust outlet, is conducive to the ventilation of water pump.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as employ the present invention design and technical solution carry out various unsubstantialities improvement, or it is not improved will
The design and technical solution of the present invention directly applies to other occasions, within protection scope of the present invention.
