Abstract
The utility model relates to a desulfurizing circulation pump which comprises a front cover, a wear-resisting plate, a vane wheel and a pump cover, wherein a bearing box is arranged in the intermediate portion of a pump shaft, the vane wheel is arranged on the top portion of the pump shaft, a packing type machine seal is arranged between the top portion of the pump shaft and the bearing box, the front cover is positioned on the top end of the pump cover, the wear-resisting plate is arranged between the front cover and the vane wheel, the screw nail adjusting mode is arranged on the joint portion of the bearing cover and the pump cover for radially adjusting the vane wheel, and the clearance between the vane wheel and a front cover plate can be retained, thereby the high efficiency of the pump is kept, moreover, the desulfurizing circulation pump has simple structure and convenient installation and use.
Description
Technical field: the utility model relates to a kind of one step single sucking formula centrifugal pump, particularly relates to a kind of desulfuration recycle pump that wet flue gas desulfurizer washing absorption towers such as power plant, steel mill recycle that is used for.
Background technique: along with the fast development of China's chemical industry, a large amount of chemical liquid media needs to carry, and most chemical mediums, not only has hypertoxicity, also has simultaneously very strong corrosivity, so in chemical industry, particularly when conveying has very strong corrosion liquid medium, impeller, the wearing plate of general pump all adopt the control ring seal form, and adopt being provided with of this mode to have maximum problem is that the setting of choma will be worn and torn fast by slurry, thereby cause the available power of pump to descend fast, increased cost of production.
Summary of the invention: for solving the existing problem of above Vintage Product, technical problem to be solved in the utility model provides a kind of simple in structure, the desulfuration recycle pump that is easy to make, the purpose of this utility model is to realize like this, desulfuration recycle pump is made up of protecgulum, wearing plate, impeller, pump cover, it is characterized in that: the middle part at pump shaft is provided with bearing housing, the top of pump shaft is provided with impeller, is provided with unit loading type machine envelope between the top of described pump shaft and bearing housing; Protecgulum is arranged on the top of pump cover, is provided with wearing plate between described protecgulum and the impeller; Joint at bearing housing and pump cover is provided with adjusting screw.The utility model is simple in structure, and is easy to maintenance, can regulate the distance between impeller and the wearing plate arbitrarily, thereby can improve the power of pump significantly.
Description of drawings: Fig. 1 is the utility model structural representation
1, protecgulum 2, wearing plate 3, impeller 4, pump cover 5, unit loading type machine envelope 6, bearing housing 7, adjusting screw 8, pump shaft
Embodiment: below in conjunction with accompanying drawing the utility model is described in further detail in the drawings, the utility model desulfuration recycle pump, formed by protecgulum, wearing plate, impeller, pump cover, it is characterized in that: the middle part at pump shaft is provided with bearing housing, the top of pump shaft is provided with impeller, is provided with unit loading type machine envelope between the top of described pump shaft and bearing housing; Protecgulum is arranged on the top of pump cover, is provided with wearing plate between described protecgulum and the impeller; Joint at bearing housing and pump cover is provided with adjusting screw.During concrete enforcement, the setting type of pump is the rear pull type structure, can regulate bearing housing by adjusting screw between bearing housing and pump cover moves forward or backward, bearing housing is arranged on the pump shaft, the mobile of bearing housing can drive moving of pump shaft, so can carry out the adjusting of axial impeller, keep the gap between impeller and front shroud and the wearing plate, thereby keep the high efficiency of pump by adjusting screw; Pump adopts the rear pull type structure, can make pump like this when maintenance, need not to dismantle the import and export pipeline of pump, greatly facilitates maintenance and maintenance; What the bearing in the bearing housing adopted is thin oil lubricant, and Bearing Installation can prevent entering of dirt and water effectively in dismountable bearing box of rubber seal auxiliary seal is arranged; Pump shaft has adopted the design of large-diameter, minor axis head, can reduce the deflection that axle is produced at work effectively, thereby prolongs the working life of pump.
