Abstract
The utility model provides an engine water pump with cooling holes and a water storage groove. The engine water pump comprises a vane wheel and a belt wheel mounted on a water pump shaft, a water seal arranged between a water pump cover and the water pump shaft, and a rolling bearing between the water pump cover and the water pump shaft, wherein the water storage groove is arranged in the water pump cover between the water seal and the rolling bearing, and the bottom of the water storage groove is downward and lower than the water seal. An axial through hole in the vane wheel is formed in the root portion of each blade, the diameter phi of each axial through hole is 2-5 mm, the axial thickness H of the water storage groove is 30 mm, the radial width L of the water storage grove is 44 mm, the radial width h is 10 mm, and an upper opening of the water storage groove is higher than the lower edge of each axial hole, wherein the height difference h1 is 2.98 mm. According to the engine water pump, the axial through holes are formed in the blades of the vane wheel, cooling liquid cools the water seal directly through the axial through holes in the vane wheel, the cooling liquid balances pressure on two end faces of the vane wheel through the axial through holes in the vane wheel, pressure difference between the two end faces of the vane wheel is lowered, axial stress of the vane wheel is reduced, and axial movement of the vane wheel is avoided. The water storage groove is arranged in the water pump cover, and therefore misjudgment of water pump leakage and efficacy loss is lowered.
Description
Technical field
The utility model belongs to the engine water pump technical field, is specifically related to a kind of engine water pump with Cooling Holes and aqua storage tank.
Background technique
Engine water pump adopts single-stage, centrifugal usually.The rotating ring of water seal and stationary ring relative rotation speed are up to 3000 rev/mins during pump working, produce amount of heat and cause temperature to raise, the cooling of at present water seal utilizes the cooling liquid in the gap of impeller and water pump cover to take away heat, and cooling effect is poor, cause that very easily water-sealing high temperature lost efficacy, and then water pump is revealed.
There is pressure difference in the impeller both ends of the surface during pump working, make impeller bear axial stress, cause the fretting wear of impeller axial motion and impeller and bearing, produce to lose efficacy.
The early stage break-in of water seal meeting is seeped water on a small quantity, and the client can think that water pump lost efficacy by mistake, but does not lose efficacy this moment, just no longer infiltration after break-in is finished.
Summary of the invention
But the purpose of this utility model is to provide a kind of effective cooling water seal simple in structure, easy to process, balance impeller both ends of the surface pressure, avoids the engine water pump with Cooling Holes and aqua storage tank of water pump leakage failure erroneous judgement.
The technical solution of the utility model: the engine water pump with Cooling Holes and aqua storage tank of the present utility model comprises impeller, the belt pulley that is installed on the water pump spindle, water seal between water pump cover and the water pump spindle, rolling bearing between water pump cover and the water pump spindle, in the water pump cover between water seal and rolling bearing aqua storage tank is set, the bottom of aqua storage tank is lower than water seal downwards.
Establish axial hole between the root of blade of described impeller and the axis hole.
The axial thickness H=30mm of described aqua storage tank, radial width L=44mm, under h=10mm, the aqua storage tank high shaft outlet hole suitable for reading along h1=2.98mm.
Axial hole on the described impeller is established one at each root of blade, the diameter of phi of axial hole=2 ~ 5mm.
Technique effect of the present utility model: the axial hole of the utility model by between the blade of impeller and axis hole, processing, cooling liquid is flowed by the gap of impeller and water pump cover and the axial hole of impeller, the pressure of balance impeller both ends of the surface, reduce the pressure difference between the impeller both ends of the surface, reduce the axial stress of impeller, avoid the inefficacies such as axial motion, impeller and axle fretting wear of impeller.Cooling liquid is directly cooled off water seal by the axial hole of impeller, and forms convection current at the axial hole of impeller and the gap of impeller and water pump cover, takes away rapidly the amount of heat that water seal produces, and reduces the water seal temperature, avoids the high temperature failure of water seal.By the aqua storage tank that under the belt pulley side end face of water pump cover, axis hole, designs, store a small amount of infiltration of water seal between running-in period, reduce water pump and reveal the erroneous judgement of losing efficacy.
