Description

Technical Field

[0001] The utility model relates to the field of water pumps, in particular to an integrated water pump for enhancing water power. Background Art

[0002] After the coolant enters the water pump from the inlet, the impeller rotates around the stator shaft. In this process, water will be thrown to the outer edge of the impeller under the action of centrifugal force, thus forming a pressure difference. Due to the gap between the impeller and the pump housing, water power loss occurs and the efficiency of the water pump decreases.

[0003] The above product adopts plate friction welding, and both the pump housing and the motor assembly are injection-molded products made of PPS+GF30 material. There are deformations and axial cumulative tolerances in the injection-molded products, resulting in the need for the gap between the pump housing and the motor product to be above 0.5 mm to avoid the risk of friction between the impeller and the end face of the pump housing.

[0004] However, when the gap between the pump housing and the motor product is too large, it will lead to low efficiency of the water pump and serious water power loss. Summary of the Invention

[0005] In order to solve the above problems, the utility model provides an integrated water pump for enhancing water power.

[0006] An integrated water pump for enhancing water power includes a pump housing, a wear-resistant gasket, an impeller rotor assembly, a motor assembly, a sealing ring, a controller assembly, and a motor rear cover, and further includes a housing gasket disposed between the pump housing and the motor assembly, and the housing gasket is integrally injection-molded with the pump housing.

[0007] Further, the housing gasket is made of stainless steel.

[0008] Further, the thickness of the housing gasket is 0.3 mm.

[0009] Further, four groups of holes are provided on the housing gasket.

[0010] Further, the four groups of holes are respectively two groups of positioning holes and two groups of plastic-coated holes.

[0011] Further, the positioning holes and the plastic-coated holes are distributed relatively.

[0012] Further, the housing gasket and the pump housing are in interference fit.

[0013] The beneficial effects of the utility model are as follows:

[0014] To solve the problem of low pump efficiency caused by hydraulic loss, a 0.3-mm stainless-steel housing gasket is added inside the pump housing during the first injection molding of the pump housing. The actual gap between the pump housing and the motor assembly is only 0.2 mm, greatly reducing the gap between the pump housing and the motor assembly and avoiding hydraulic loss. The utility model solves the problem of cumulative axial tolerance in product injection deformation and at the same time solves the problem of product hydraulic efficiency, making the entire water pump have a longer service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below.

[0024] As Figures 1 to 5 shown, an integrated water pump for enhancing hydraulics includes a pump housing 1, a wear-resistant gasket 2, an impeller rotor assembly 3, a motor assembly 4, a sealing ring 5, a controller assembly 6, and a motor rear cover 7, and further includes a housing gasket 8 disposed between the pump housing 1 and the motor assembly 4, and the housing gasket 8 is integrally injection-molded with the pump housing 1.

[0025] As Figure 4 shown by reference numeral 11 in the drawing, it is the plastic-coated housing location.

[0026] In order to solve the problem of low pump efficiency caused by hydraulic loss, a 0.3-mm stainless-steel housing gasket 8 is added inside the pump housing 1 during the first injection molding. The actual gap between the pump housing 1 and the motor assembly 4 is only 0.2 mm, greatly reducing the gap between the pump housing 1 and the motor assembly 4 and avoiding hydraulic loss.

[0027] As Figure 4 shown, the housing gasket 8 is made of stainless steel, and the material is wear-resistant, which prolongs the service life of the water pump.

[0028] Moreover, since the technical solution of wrapping the plastic housing gasket 8 inside the pump housing 1 is adopted in the present utility model, the adopted housing gasket 8 is not easily deformed and is wear-resistant. The wear-resistant gasket 2 is axially limited. If the housing gasket 8 is worn, with the upward buoyancy of the impeller rotor assembly 3, the impeller rotor assembly 3 and the pump housing 1 will have the opportunity to rub against the housing. Therefore, the present utility model solves the problem of cumulative axial tolerance of product injection deformation and at the same time solves the problem of low hydraulic efficiency of the product, making the entire water pump have a longer service life.

[0029] As Figure 1 、 Figure 3 and Figure 4 shown, the thickness of the housing gasket 8 is 0.3 mm, with the upward buoyancy of the impeller rotor assembly 3.

[0030] As Figure 4 shown, four groups of holes are provided on the housing gasket 8.

[0031] Specifically, the four groups of holes are two groups of positioning holes 9 and two groups of plastic-encapsulating holes 10. The two groups of positioning holes 9 are used for positioning the housing gasket 8 in the mold for convenient product injection molding. The two groups of plastic-encapsulating holes 10 are used for the plastic encapsulation of the pump housing 1 to inject glue, preventing the housing gasket 8 from making a radial rotational movement during the injection molding process and ensuring the molding quality after injection molding.

[0032] As Figure 3 shown, the positioning holes 9 and the plastic-encapsulating holes 10 are distributed relatively, so as to prevent interference.

[0033] As Figure 2 and Figure 5 shown, the housing gasket 8 and the pump housing 1 are in interference fit to prevent axial detachment.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
