Abstract
The utility model discloses a water pump, which includes a pump body made of aluminium alloy, wherein a layer of anode oxide film is formed on the inner surface of the pump body through hard anodization, thereby prolonging the service life of the pump. The water pump provided by the utility model aims to solve the problems of high possibilities of fracture, corrosion and abrasion of the pump body of the existing water pump.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of water pump of handling through hard anodized.
Background technique
Water pump is widely used in many occasions such as cleaning, pesticide spraying, the conveying of lathe working solution.
Hydraulic pressure in the water pump is very high, and its pump housing is impacted by high hydraulic pressure for a long time.So a general water pump is easy to occur the phenomenon that the pump housing breaks after using 2 years.
In addition, if when water pump is carried the Korrosionsmedium water of corrosive impurity (as contain), can carry the pump housing is not that pump housing internal surface produces corrosion.
Plunger pump is a kind of in the water pump, and it is a kind of small flow high-pressure service pump, and when work, the plunger of plunger pump is done the to-and-fro motion of high speed in the pump housing, and plunger and pump housing internal surface produce high-intensity friction, go down for a long time and can cause the wearing and tearing of the pump housing.
The water pump of existing multiple model all is directed against the problems referred to above and has done improvement, yet does not all obtain good achievement.
Summary of the invention
The utility model purpose is: a kind of water pump is provided, is intended to solve that the pump housing that present water pump exists is prone to break, problem perishable, easy to wear.
The technological scheme of the utility model is: a kind of water pump comprises it is characterized in that the pump housing of aluminum alloy material: the said pump housing through hard anodized handle and within it the surface be formed with one deck anode oxide film, thereby improve the working life of water pump.
The outer surface of the said pump housing also is formed with one deck anode oxide film.
The thickness of said anode oxide film is 1 ~ 6um.
Said water pump is plunger pump or reciprocating pump.
The beneficial effect of the utility model is: the pump housing of the utility model water pump is through the hard anodized processing and be formed with one deck anode oxide film at pump housing internal surface, and anode oxide film is attached to pump housing internal surface difficult drop-off.This anode oxide film has fabulous oxidation resistance, and can make pump housing hardness reach 1000 ~ 1200HV, has improved the working life of water pump greatly, especially plunger pump or reciprocating pump is had significant effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the utility model embodiment's a structural representation;
Wherein: the 1-pump housing, 2-anode oxide film.
Embodiment
As shown in Figure 1; The water pump of present embodiment comprises that the pump housing 1 of water pump and the pump housing are aluminum alloy material; This pump housing 1 is through the hard anodized processing and be formed with one deck anode oxide film 2 at pump housing internal surface (this internal surface comprises the chamber wall of pump housing inner cavity chamber, the hole wall of tapped hole, the sidewall of flow channel etc.), and the thickness of anode oxide film 2 is generally 1 ~ 6um.This anode oxide film 2 has fabulous oxidation resistance, has strengthened the intensity of the pump housing, can make pump housing hardness reach 1000 ~ 1200HV (Vickers hardness), thereby has overcome the shortcoming that pump housing internal surface is prone to be worn, the working life of having improved water pump.
In addition, in order further to optimize the corrosion-resistant and high hardness performance of the pump housing 1, this example also is formed with one deck anode oxide film 2 at the outer surface of the pump housing 1, and outer field anode oxide film 2 also is to form through the hard anodized of the pump housing 1 is handled.
Generally, only need that the pump housing 1 is carried out a hard anodized and handle, just can form anode oxide film 2 simultaneously at pump housing internal surface and pump housing outer surface.
The claimant finds that the water pump of the utility model is after having used 1 year, and its pump housing inner and outer surface does not all have noticeable wear, and the pump housing does not have the cracking vestige yet, is more than 3 years its working life through surveying.
Certainly, the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets the people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
Claims (3)
