Often there is accidental drainage in abrasion, causes coolant loss and the hidden danger such as internal pressure relief, causes water pump not use.
The content of the invention
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of water pump, its is simple in construction
Rationally, sealing ring is set between the pump housing and pump cover, water oil sealing is arranged on pump shaft, water route is separated by water oil sealing and sealing ring
Area and oil circuit area, the degree of wear is small, high lubricating effect, can prevent the phenomenon of leak pressure release from occurring, extend the use of water pump
Life-span.
To achieve the above object, the utility model uses following technical scheme.
A kind of water pump described in the utility model, including the pump housing, pump cover and pump shaft, axis fixing plate, axle are provided with the pump housing
Fixing plate clamp is held in one end of pump shaft, and the other end of pump shaft is arranged in pump cover through the pump housing, and pump shaft is close on one end of pump cover
Impeller is provided with, bearing is provided between the pump housing and pump shaft, pump housing bottom is provided with oil circuit area, set between pump housing top and pump cover
Water route area is equipped with, sealing ring is provided between the pump housing and pump cover, water oil sealing is arranged with pump shaft, passes through water oil sealing and sealing ring point
Water proof road area and oil circuit area.
Further, the bottom of the pump housing is additionally provided with sealing steel plate and sealing paper washer, axis fixing plate, sealing steel plate and sealing
Paper washer is provided with oil-through hole.
Further, the hydraulic fluid port connected with oil circuit area is provided with the pump housing.
Further, the water inlet and delivery port connected with water route area is provided with the pump housing, the side of delivery port is provided with
Plug.
Further, the pump housing is bolted to connection with pump cover.
The utility model has the beneficial effect that：The utility model sets sealing ring between the pump housing and pump cover, is covered on pump shaft
If water oil sealing, water route area and oil circuit area are separated by water oil sealing and sealing ring, the degree of wear is small, high lubricating effect, can prevent
The phenomenon of leak pressure release occurs, and extends the service life of water pump.The utility model is simple and reasonable, and friction degree is small, damage
Consumption degree is low, high lubricating effect, extends the service life of water pump.
