Abstract
The utility model relates to a novel pump with a metal coating, which comprises a pump casing, an impeller and blades, wherein the impeller is mounted in the pump casing and the blades are mounted onthe impeller. The novel pump with a metal coating is characterized in that a layer of smooth metal coating is uniformly arranged on all flow-through portions of the pump casing, the impeller and the blades, thereby being capable of resolving the corrosion problem well, reducing friction force, achieving high wear resistance simultaneously and prolonging service life of the pump greatly. The novelpump with a metal coating overcomes shortages of the prior art and is simple in construction. The metal coating has strong adhesive property, excellent corrosion resistance and wear and erosion resistance, is 100% in solid content without volatilization and contraction during solidification, and has a protection function on flow-through parts of the water pump, thereby prolonging the service lifeof the water pump.
Description
Technical field
The utility model relates to a kind of novel metal coating pump.
Background technique
Pump is in people's life and production, have extremely widely and use, but existing Centrifugal water pump, the most casting techniques that adopt of pump case and impeller, the Part Surface Roughness of casting is low, friction factor is big, cause the efficient of water pump low, the shaggy method of present domestic raising has polishing, spraying, line with rubber etc., polishing not only are subjected to the interior spatial constraints of the pump housing but also can't reach desirable effect, the spraying fitness for purpose polishes smooth earlier, roughness is subject to the surface condition before the spraying, though methods such as line with rubber can reach desirable effect, and complex process, limited by the interior die cavity of pump, and not environmental protection.Because liquid has very high flow velocity in the pump, so domestic existing coating all comes off easily at present.
The model utility content
In order to solve problems of the prior art, the utility model provides a kind of smooth surface, corrosion-resistant, the wear-resisting and novel metal coating pump that can raise the efficiency.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel metal coating pump, it comprises pump case, impeller, blade, impeller is installed in the pump case, blade is installed on the impeller, it is characterized in that: on all overcurrent parts, impeller and the blade of pump case, the smooth metallic coating of one deck is set evenly, just can solve etching problem well and the power of reducing friction, also have high wear resistance simultaneously, can strengthen the working life of pump greatly.
New and effective centrifugal pump of the present utility model, overcome the shortcoming of prior art, construction is simple, only need be as paint with the surface of metallic coating spary at pump case or impeller, because this metallic coating has the advantages that to shakeout automatically, so the parent surface quality to pump case is less demanding, metallic coating can be supplied the rejected region rear surface automatically and reach smooth smooth effect.This metallic coating has extremely strong adhesive property, splendid corrosion resistance, and wear-resisting anti-washing away.100% solid content, solidification process do not have volatilization, do not have and shrink.Dry film wet film uniform thickness does not pollute environment, has very smooth surface, can reduce during the pump work frictional force with fluid greatly, makes energy consumption reduce.Coating heat resistent property height, for many applications, dry environment can reach 150 ℃, 60 ℃ of wet environments.Press ASTM E288 test, rates of thermal expansion is 74.7ppm/ ℃.Coating plays protective action to the water pump flow passage part, prolongs the working life of water pump, and remarkable energy saving effect is arranged, and makes old pump energy-conservation 7%.This technology can improve the anti-cavitation ability of water pump, prolongs the working life of impeller.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
