Description
Technical field
The utility model relates to a kind of device of alleviating the cavitation erosion of titanium tetrachloride transfer pump, belongs to chemical industry titanium tetrachloride production technical field.
Background technique
At present, chemical industry, in crude titanic chloride course of conveying, owing to containing HCl, Cl in crude titanic chloride
2deng corrosive gas and a small amount of solid particle, so the parts such as inlet ductwork of Under Water Pumps, pump cover liner, impeller are easily corroded, wear and tear, and cause the working life of transfer pump under liquid partially short.
Model utility content
The utility model object is to provide a kind of device of alleviating the cavitation erosion of titanium tetrachloride transfer pump, adopts pump housing inlet size to be greater than pump housing outlet size, guarantees that the pressure at the impeller back side is greater than the pressure for vaporization of titanium tetrachloride, has reduced cavitation erosion.Solve the problem existing in background technique.
The technical solution of the utility model is: a kind of device of alleviating the cavitation erosion of titanium tetrachloride transfer pump, comprise pump housing import, pump housing outlet, the pump housing and impeller, pump housing import and pump housing outlet are located at respectively on the pump housing, and pump housing inlet size is greater than pump housing outlet, impeller is located on the pump shaft in the pump housing, and pump shaft is connected with driving mechanism.
Described impeller is half-opened impeller, and impeller is provided with blade B, and blade B length alternately arranges, makes that flow is more stable, pump housing operation is more steady, thereby has reached the object that reduces cavitation erosion harm.
Described impeller is unshrouded impeller, and impeller is provided with blade A, and blade A angle is greater than NBS.Unshrouded impeller, by strengthening blade angle, strengthens pump housing inlet flow rate, makes the pressure that the inlet of impeller provides be greater than the pressure for vaporization of this medium at this temperature, and then has reduced the harm of cavitation erosion to the pump housing.
It is high-chromium alloy that impeller is selected material, and cavitation resistive property is stronger, or selects the good Cr30 of corrosion resistance, improves the working life of impeller.
The pump housing can adopt double flow channel or multiple flow passages, makes pump operation more steady.
The liner of the pump housing, pump cover adopts ceramic products, improves working life.
The beneficial effects of the utility model are: reduced the cavitation erosion of the pump housing, improved the working life of transfer pump, reduced cost of production.
