Abstract
The utility model discloses a rubber-liner desulfurization pump, the structure thereof comprises a pump body, a pump cover and an impeller, and the key improvement thereof is as follows: the inner surfaces of the split-mounting-type pump body and the pump cover are attached with rubber protecting jacket couplers. The rubber-liner desulfurization pump has the following advantages: the inner walls of the pump body and the pump cover are respectively provided with the protecting jacket which can form a complete sealing line, therefore, when being worn, the protecting jacket can be directly replaced without replacing the whole pump head, thus reducing the production cost.
Description
Technical field
The utility model relates to the pump of carrying corrosive liquids, particularly a kind of line with rubber desulfur pump.
Background technique
At chemical industry; in the industrial production such as smelting iron and steel and sewage treatment; produce a large amount of flue gas and stronger liquid of pH value that contain sulfur dioxide etc. through regular meeting; flue gas and the pH value liquid that is produced can pollute environment on the one hand; the part resource of reusable edible causes waste on the other hand; cause damage to enterprise; so to the waste gas that contains the reusable edible resource and will further handle; waste liquid must carry out further collection and treatment; the flue gas that contains sulfur dioxide etc. is being carried out carrying out will carrying in the further processing procedure in the wet-treating process and to pH value liquid; the liquid of being carried not only is corrosive; but also be mixed with the fine particle thing; so liquid delivery pump has been proposed higher requirement, should be corrosion-resistant also wear-resisting.
Comprise the pump housing, pump cover in the existing desulfur pump structure, suction cover, wearing piece, impeller and Sealing, described member adopts corrosion-resistant, wear-resisting metallic material substantially, but because the liquid acid alkali concn of being carried is higher, and contain the fine particle thing, use a period of time metal erosion, wearing and tearing will occur, and produce the situation of leakage, so just necessary integral replacing pump head brings loss to enterprise.
In order to solve short problem in working life; also has a kind of corrosion-resistant, wear-resisting polythene material Global Macros cover that adopts in the existing desulfur pump; though this kind technological scheme has prolonged the working life of whole desulfur pump; but the protection of the polyethylene of this technological scheme is the Global Macros cover; adopted the lining molding technology; if but after the protecting jacket wearing and tearing, still want the integral replacing pump head, cause damage.
The model utility content
Technical problem to be solved in the utility model provides a kind of desulfur pump working life of can improving, and reduces the line with rubber desulfur pump of equipment cost.
The technological scheme of Cai Yonging is for achieving the above object: the line with rubber desulfur pump, comprise the pump housing in its structure, and pump cover, impeller, its key improvements is: adhere on the internal surface of the pump housing and pump cover rubber protecting jacket male part is set.
Adopt the beneficial effect that technique scheme produced to be: the protecting jacket that can form the complete seal line is installed on the pump housing and pump cover inwall respectively; when wearing and tearing appear in protecting jacket; directly change protecting jacket and get final product, need not change whole pump head, reduce production costs.
