Abstract
The utility model discloses an abrasion-resistant and corrosion-resistant chemical centrifugal pump which is applied to delivering corrosive liquid containing fiber media such as solid particles in the papermaking chemical industry, the food industry, the environmental protection engineering industry and the like. The abrasion-resistant and corrosion-resistant chemical centrifugal pump comprises a pump body, an impeller, a pump shaft, a hanger bracket and a pump cover, the pump shaft is fixed into the hanger bracket, the pump cover is sleeved on the pump shaft and fixed onto the hanger bracket, the pump body is fixed onto the hanger bracket, a front lining plate is disposed between the pump body and the impeller, and a rear lining plate is arranged between the pump cover and the impeller. As the front lining plate and the rear lining plate which are made of corrosion-resistant and abrasion-resistant materials are disposed between the pump body and the impeller, corrosion resistance and abrasion resistance of the pump body are improved, and the service life of the pump body is prolonged. In addition, gaps among the front lining plate, the rear lining plate and the impeller can be adjusted after the impeller is abraded, so that the pump is in a good working state, the service life of the impeller is prolonged, and the pump is good in abrasion resistance and corrosion resistance.
Description
Technical field
The utility model relates to a kind of centrifugal pump, relates in particular to a kind of chemical centrifugal pump that industries such as papermaking chemical industry, food and environment-friendly engineering are carried the corrosive liquids that contains fiber mediums such as solid particle that is applied to.
Background technique
The wear resistant corrosion resistant chemical centrifugal pump can be widely used in industries such as paper mill, food processing and environmental protection and carry the slurries that contain the abrasion solid particle, like the conveying of paper mill paper pulp.In chemical industry, also can carry some to contain the corrosivity slurries of crystalline solid.The material of employed in the market wear resistant corrosion resistant chemical centrifugal pump is U.S. mark 304, or the two-phase Neutral Steel, though have certain decay resistance; But its wear-resisting property is relatively poor, and after the long-time running of pump, wear phenomenon can appear in the pump housing and impeller; In case wearing and tearing surpass certain scope, the transfer efficiency of pump just descends significantly, and the noise of pump operation can be multiplied; Must change the pump housing and impeller etc., the wear resistant corrosion resistant chemical centrifugal pump should wear-resisting good corrosion resistance again for this reason, but the good pump of wear resistance is with its corrosion-resistant of material; The material of good corrosion resistance again can not be wear-resisting; This is the insoluble a great problem of wear resistant corrosion resistant chemical centrifugal pump always, so this type of centrifugal pump is the high flow rate article, wear-resisting problem can't effectively improve and solve always.
The model utility content
The utility model purpose is to provide a kind of wear resistant corrosion resistant chemical centrifugal pump of new structure; Between the pump housing, pump cover and impeller, be provided with the forward and backward liner plate that the anticorrosive wear-resistant material is processed; Improve the working life of the pump housing; After wearing and tearing appear in impeller, can pump be in the good working order simultaneously, prolong the working life of impeller through the position of regulating liner plate.
The technological scheme of the utility model is achieved in that
A kind of wear resistant corrosion resistant chemical centrifugal pump comprises the pump housing, impeller, pump shaft, suspension and pump cover, and said pump shaft is fixed in the said suspension; On described pump shaft, be set with described pump cover; Said pump cover is fixed on the said suspension, and said impeller is fixed on an end of said pump shaft, and the said pump housing is fixed on the said suspension; It is characterized in that: be provided with preceding liner plate between the said pump housing and the impeller, this preceding liner plate is fixed on the said pump housing; Between said pump cover and impeller, be provided with rear lining plate, this rear lining plate is fixed on the said pump cover.
Before said between the liner plate and the pump housing, between rear lining plate and the pump cover, be provided with liner.
The utility model compared with prior art has following advantage:
1. owing between the pump housing, pump cover and impeller, be provided with preceding liner plate and the rear lining plate that the anticorrosive wear-resistant material is processed, improve the corrosion-resistant and wear-resisting property of the pump housing, prolonged the working life of the pump housing.
2. after wearing and tearing appear in impeller; Can regulate the position of forward and backward liner plate through the liner that adopts different-thickness; Reach the gap of regulating between forward and backward liner plate and the impeller; Pump is in the good working order, has prolonged the working life of impeller, this pump has good abrasion resistance and decay resistance.
