Description
Technical Field
The utility model discloses water pump shell technical field especially relates to the field that overflows position surface treatment, specifically is a water pump shell with wear-resisting, corrosion resisting property.
Background
In order to reduce the cost, the water pump housing is usually made of cast iron, and the inner flow passage is painted to achieve the purpose of corrosion prevention. When a water pump conveys a medium with strong corrosivity (such as seawater), the shell made of cast iron still cannot meet the use condition after being painted, and only a stainless steel material with a higher grade can be selected. Stainless steel is expensive and wood-type and iron castings are not versatile, resulting in a large increase in manufacturing costs. Secondly, stainless steel casting is more easy to produce casting defect than iron casting, and later stage restoration cost is high. Therefore, it is an urgent requirement to design a wear-resistant water pump housing with wear resistance and corrosion resistance.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: a wear resistant water pump housing is provided.
The to-be-solved technical problem of the utility model is that: a water pump shell with wear resistance and corrosion resistance is characterized in that a composite coating is arranged on the inner wall of an overflowing part of the shell.
Preferably, the composite coating is a cermet.
More preferably, the cermet is a structural material consisting of a ceramic hard phase and a metal or alloy binder phase.
Preferably, the inner wall of the overflowing part is provided with a line bulge along the water flow direction.
Preferably, the line protrusions form a flow channel, and the direction of the flow channel is consistent with the direction of the water flow rotating in the axial direction.
Preferably, four line bulges are arranged.
Preferably, the grain protrusions are provided with composite coatings.
Preferably, the composite coating on the grain protrusions is made of metal ceramic.
The utility model has the advantages that:
the inner wall surface of the water pump achieves the beneficial effects of abrasion resistance and corrosion resistance.

Detailed Description
In order to make the technical solutions and the advantages of the present invention clearer, the following is a further detailed explanation of the embodiments of the present invention.
The utility model provides a water pump shell with wear-resisting, corrosion resisting property, the inner wall that the casing overflows the position is equipped with composite coating 100. The composite coating is metal ceramic. The cermet is a structural material consisting of a ceramic hard phase and a metal or alloy binder phase.
In order to improve the corrosion resistance, ni element is added into the original cast iron material, so that the corrosion resistance of the shell is improved.
The ceramic-metal composite coating is sprayed on the overflowing part (non-matching part) of the shell to realize the anti-corrosion effect. The metal ceramic is a structural material consisting of a ceramic hard phase and a metal or alloy bonding phase, the spraying process of the coating is simple and easy to operate, the coating has high hardness, is resistant to scouring, corrosion and high temperature, and can effectively prolong the service life of the shell; the cost is low, the later maintenance is convenient, and the environment is protected without pollution; the surface finish degree is high after the casing runner is sprayed, the performance loss of the water pump in operation is reduced, the efficiency of the water pump is improved, and energy is saved. Sealant is coated on the overflowing part of the shell matched with other parts.
When a medium with higher corrosivity is conveyed, the shell is made of a cast iron material and a coating instead of a stainless steel material, so that the price is low, the cost for newly manufacturing a cast wood mold is not increased, and the cost is greatly reduced; and the probability of casting defects of the iron casting is lower than that of the stainless steel casting, so that the reject ratio of the product is reduced.
The spraying process of the composite coating is simple and easy to operate, has high hardness, is resistant to scouring and corrosion, and can effectively prolong the service life of the shell; the composite coating has low cost and convenient later maintenance, and is green, environment-friendly and pollution-free; the surface smoothness is improved after the casing runner is sprayed, the performance loss of the water pump in operation is reduced, the efficiency of the water pump is improved, and energy is saved.
In order to reduce the impact on the shell, the inner wall of the overflowing part is provided with a line bulge 200 along the water flow direction. Impact is transferred to the textured bumps 200, thereby reducing damage to the housing.
Further, the line protrusions 200 form a flow channel, and the direction of the flow channel is consistent with the direction of the water flow rotating in the axial direction.
The line bulges 200 are provided with four, eight, sixteen or more lines, and the formed flow passages achieve the effect of buffering impact. In order to improve the effects of abrasion resistance and corrosion resistance, a composite coating 100 is provided on the textured protrusions 200. And the composite coating 100 on the textured protrusions 200 is a cermet.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and various changes and modifications can be made by workers without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and all equivalent changes and modifications in the shape, structure, characteristics and spirit according to the scope of the present invention are intended to be included in the scope of the claims of the present invention.
