Abstract
The utility model relates to a water pump assembly, in particular to a water pump assembly with a gray cast iron impeller, which mainly aims at solving the technical problems that the existing impeller of a water pump in the prior art is made of plastic, and the matching of the plastic of a core shaft of the impeller is poor, so that the shedding phenomenon of plastic blades occurs when a product is in use, the shrinkage deformation of the plastic is relatively serious, and the jumping of the impeller is relatively difficult to control so as to bring adverse affects and the like to the performances of the product. The water pump assembly comprises a blank cap (1), the blank cap is connected with a pump body (3) through a flange (2), and the water pump assembly is characterized in that a shaft connecting bearing (4) is arranged in the pump body (3), a shaft body part at the lower end of the shaft connecting bearing is connected with an impeller component (5), the impeller component is casted by gray cast iron, and a water seal assembly (6) is arranged on the shaft body of the shaft connecting bearing.
Description
Technical field
The utility model relates to a kind of water pump complement, especially relates to a kind of isostructural improvement of water pump complement to band gray cast iron impeller.
Background technique
Generally all need to use water pump in daily life, general water pump all is made up of the pump housing and impeller, can play the effect of drawing water.Chinese patent discloses a kind of plastic impeller water pump (notice of authorization number: CN201090503Y), it comprises the pump housing and impeller, impeller comprises wheel hub, cover plate, the blade that plastics are made, be embedded with metal lining in the wheel hub of impeller, the outer wall of metal lining is provided with some equally distributed projections, and projection is serration or rectangular protrusions.Chinese patent also discloses a kind of plastic water pump (notice of authorization number: CN201027686Y), it comprises water pump cover and water pump base, having through hole in this water pump base communicates with the inner chamber of water pump cover, 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 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 plastics flange dish, the water pump cover lower inner wall is a smooth surface, and cylinder outer wall is provided with three stiffening ribs according to 120 degree angle five equilibriums, and the stiffening rib lower end surface has tapped hole, the upper-end surface of described plastics flange dish has tapped hole correspondence with it, and described bolt is installed in two tapped holes.But the impeller of this water pump all is made of plastics, the plastics of the mandrel of its impeller cooperate bad, the phenomenon that makes product in use have plastic blade to come off, and the plastic shrink deformation ratio is more serious, the also difficult control of beating of impeller brings bad influence for the performance of product.
Summary of the invention
The utility model technical issues that need to address provide a kind of water pump complement with the gray cast iron impeller, it mainly is that the impeller that solves the existing in prior technology water pump all is made of plastics, the plastics of the mandrel of its impeller cooperate bad, the phenomenon that makes product in use have plastic blade to come off, and the plastic shrink deformation ratio is more serious, the also difficult control of beating of impeller brings the technical problem of bad influence etc. for the performance of product.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The water pump complement of band gray cast iron impeller of the present utility model, comprise stifle, stifle is connected with the pump housing by flange, it is characterized in that described pump housing inside is provided with shaft connecting bearing, the axis body of shaft connecting bearing lower end partly is connected with impeller assembly, impeller assembly is that the gray cast iron casting forms, and the axis body of shaft connecting bearing is provided with the water seal assembly.Impeller assembly is formed by the direct precision casting of gray cast iron, and impeller assembly becomes one, and adopts machining to take care of yourself the form and position tolerance and the tolerance of size of product after the moulding, has so just solved the shortcoming that plastic blade comes off easily and is out of shape.Flange can be fixed on the stifle by bolt, thereby the pump housing is fixed, and flange can be made by powder metallurgy.After the pump housing installed, by the rotation of motor driving shaft connecting bearing, the impeller assembly that is installed on the shaft connecting bearing can be rotated, thereby carries out pump drainage water.
As preferably, described water seal assembly includes Sealing, is connected with damping spring on the Sealing.The water seal assembly can prevent that sealing overflows from water pump inside, and the Sealing of water seal assembly can be made by rubber material, and damping spring can be given the certain pressure of water seal assembly, prevents it and is dashed because hydraulic pressure is excessive.
As preferably, the described pump housing be provided with flange, the lower surface of flange is provided with pump housing Sealing.After the pump housing is installed on other parts, can be excessive by the anti-sealing of pump housing Sealing.
Therefore, the impeller assembly that the utlity model has water pump is formed by the gray cast iron precision casting, makes water pump blade difficult drop-off or torsional deformation in use, prevents that blade from beating, characteristics such as the working life of water pump is longer, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
Component, position and numbering among the figure: stifle 1, flange 2, the pump housing 3, shaft connecting bearing 4, impeller assembly 5, water seal assembly 6, pump housing Sealing 7.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the water pump complement of the band gray cast iron impeller of this example, as Fig. 1, Fig. 2, a stifle 1 is arranged, stifle is connected with the pump housing 3 by flange 2, the pump housing 3 be provided with flange, the lower surface of flange is provided with pump housing Sealing 7.The pump housing 3 inside are provided with shaft connecting bearing 4, and the axis body of shaft connecting bearing is provided with water seal assembly 6, and water seal assembly 6 includes Sealing, are connected with damping spring on the Sealing.The axis body of shaft connecting bearing lower end partly is connected with impeller assembly 5.Impeller assembly is that the gray cast iron casting forms.
During use, start motor, motor driving shaft connecting bearing 4 is rotated, and shaft connecting bearing can drive connection impeller assembly 5 thereon and be rotated, thereby finishes pump drainage water.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
