Abstract
The utility model discloses a pump cover of a waste acid concentrate axial-flow pump for conveying various strong corrosive liquids in the field of chemical industry. The pump cover comprises a front pump cover and a rear pump cover, the front pump cover and the rear pump cover are both formed by metal inserts and linings fixed onto the metal inserts by adopting the modes of inner lining outer covering or steel lining. On the one hand, the pump cover can increase the strength of the front pump cover and the rear pump cover; on the other hand, the pump cover can prevent deformation and cracking damage of the front pump cover and the rear pump cover caused by expansion on heating and contraction on cooling when high temperature and low temperature rapidly change, thereby improving bonding strength between the linings and the metal inserts and further prolonging the service life of the front pump cover and the rear pump cover. The pump cover is widely applied to the waste acid concentrate axial-flow pump in industrial production processes such as titanium dioxide industry, steel industry, phosphorous chemical industry, organic chemical industry and the like.
Description
Technical field
The utility model relates to the chemical pump that a kind of chemical field is carried various strongly corrosion liquids, relates in particular to a kind of pump cover of waste acid concentration axial flow pump.
Background technique
Along with the continuous development of science and technology, to adopt lining fluorine pump when chemical field is carried strongly corrosion liquid now, promptly the overcurrent of pump partly adopts the fluoroplastic compression molding, has so just guaranteed the corrosion resistance of pump.As in industrial processes such as titanium white industry, steel industry, phosphorous chemical industry, the industry that organises, all needing the acid of using in enormous quantities, also can produce a large amount of spent acid simultaneously, these acid pump that adopts when carrying has corrosion-resistant mixed flow pump and axial-flow pump etc.In the spent acid callback course, generally need carry out repeatedly concentrating to spent acid, along with concentrating of spent acid, the concentration of acid also can be more and more higher, the corrosion resistant nonmetallic material manufacturing of the normal employing of the pump cover of existing for this reason mixed flow pump and axial-flow pump, but this pump cover is under high and low temperature bad working environments jumpy, owing to causing distortion, cracking, the reason of expanding with heat and contract with cold damages, greatly influenced its working life, the intensity of this pump cover does not have the good of metallic material simultaneously, has influenced its working life to a certain extent yet.
The model utility content
The utility model purpose is to provide a kind of pump cover of waste acid concentration axial flow pump of new structure, in forward and backward pump cover, metal insert is set, can eliminate the waste acid concentration axial flow pump reason of when the high and low temperature rapid change, expanding with heat and contract with cold and cause the forward and backward pump cover distortion that nonmetallic material make, the phenomenon that cracking damages, greatly improve its working life.
Another purpose of the utility model is to provide a kind of pump cover of waste acid concentration axial flow pump of new structure, before and after pump cover adopt a kind of in fluoroplastic, glass fibre reinforced plastics, enamel, graphite or the carbon fiber overall structure, solve yielding, the cracking phenomena of existing pump cover, increase substantially the intensity of pump cover, greatly improved working life.
The technical solution of the utility model is achieved in that
The pump cover of waste acid concentration axial flow pump comprises front pump cover and rear pump cover, it is characterized in that: described front pump cover and rear pump cover are formed by metal insert and lining, and described lining adopts liner outsourcing or steel lining form to be fixed on the described metal insert.
The metal insert of described liner externally-packed structure is provided with several holes or dovetail groove or stiffening rib.
Described hole is through hole or half through hole or tapped hole.
Described steel lining form is a rivet arrangement, and described metal insert is provided with several through holes, in a side of described through hole metal cap is arranged, the long-pending sectional area greater than described through hole of the intracavity section of described metal cap.
Described lining is a kind of in fluoroplastics layer, frp layer, enamel layer, graphite layer or the carbon fiber layer.
One of described front pump cover and rear pump cover or whole the employing radially or axial split composite structure.
Described split composite structure is a kind of in two, three or four the split composite structures.
The pump cover of waste acid concentration axial flow pump comprises front pump cover and rear pump cover, it is characterized in that: described forward and backward pump cover adopts a kind of in fluoroplastic, glass fibre reinforced plastics, enamel, graphite or the carbon fiber overall structure.
The utility model compared with prior art has following advantage:
1. owing in the pump cover of front and back, be provided with metal insert, the intensity of pump cover before and after increasing on the one hand, pump cover distortion before and after the reason that prevents from the other hand to expand with heat and contract with cold when the high and low temperature rapid change causes, the phenomenon of damaging that ftractures occur, the working life of pump cover before and after having improved.
2. lining adopts liner outsourcing or rivet arrangement to be fixed on the metal insert, has improved the adhesive strength of lining and metal insert, the working life of pump cover before and after further improving.
3. metal insert is provided with several holes or dovetail groove or stiffening rib, further improves the adhesive strength of lining and metal insert.
4. the front and back pump cover adopts a kind of in fluoroplastic, glass fibre reinforced plastics, enamel, graphite or the carbon fiber overall structure.Can select arbitrarily according to the Environmental Conditions of pump and the price of pump, make pump have good cost performance.
5. one of described front pump cover and rear pump cover or all adopt radially or axial two, three or four split composite structures in a kind of, so both made things convenient for installation, made things convenient for processing again.
