Technical field
The utility model belongs to water pump, specifically, is a kind of plastic water pump.
Background technique
Present water pump all comprises water pump cover, water pump base and the water pump pump machine of cast iron; Water pump pump machine is installed in the water pump cover, as shown in Figure 5, with bolt the water pump base is fixed on the lower end of water pump cover, the water pump base is fixed together with engine body again, after being convenient to motor and passing cavity in the water pump base, the water pump pump machine work in the control of pump housing.
Its shortcoming is: the cost height of iron water pump, weight be big, be not easy to transport operation, long period of soaking in water, corrosion easily.
The model utility content
The purpose of this utility model provides a kind of plastic water pump, can reduce cost, alleviate the weight of water pump.
For achieving the above object, a kind of plastic water pump described in the utility model, comprise water pump cover and water pump base, having through hole in this water pump base communicates with the inner chamber of water pump cover, its key is: described water pump cover and water pump base all are plastic casing, wherein the water pump base is formed by connecting by plastics pedestal and plastics flange dish, wherein plastics pedestal top is plastic disc, lower central is a plastic cylinder, this cylinder outer wall is distributed with stiffening rib, fixedly connected with described water pump cover in the upper-end surface of this plastics pedestal, bolt is connected between the upper-end surface of lower end surface and described plastics flange dish.
Water pump cover and water pump base all change working of plastics into, have alleviated the quality of water pump, also are convenient to transport operation, have reduced the fabricating cost and the installation cost of water pump, and simultaneously, working of plastics has the characteristic of acid resistant alkali, also can corrosion in the long period of soaking water.
Described water pump cover lower inner wall is a smooth surface.
Original water pump cover lower inner wall has a circle boss, be unfavorable for the demoulding of working of plastics, change inwall into smooth surface, solve the release problems of plastic casing, can realize the time processing moulding of water pump cover, simultaneously, change by the water pump cover cavity shape, increased space in the pump, improved suction journey, lift and the flow of water pump, the whole performance quality that improves water pump.
Described cylinder outer wall is provided with three stiffening ribs according to 120 degree angle five equilibriums.
Stiffening rib improves the stability of plastics pedestal, makes it can reach the load-bearing effect same with cast iron base.
Described stiffening rib lower end surface has tapped hole, and the upper-end surface of described plastics flange dish has tapped hole correspondence with it, and described bolt is installed in two tapped holes.
Different motors are different with the installation dimension of water pump, and bolt is connected between the plastics flange dish of plastics pedestal and different size, by replacing plastics flange dish, has solved the installation matching problem of different motors and water pump.
Remarkable result of the present utility model is: a kind of plastic water pump is provided, can reduce water pump fabricating cost and installation cost, alleviate the weight of water pump, be convenient to transport operation, acid resistant alkali, can corrosion, simultaneously, improve suction journey, lift and the flow of water pump, the whole performance quality that improves water pump can be complementary water pump with the motor of different model.
