Abstract
A kind of Horizontal slurry pump, comprise bearing housing, impeller, pump shaft, form by front pump cover, rear pump cover, apron plate, rear backplate, sheath the blade wheel chamber having double pump shell structure, pump shaft end is provided with impeller by impeller nut, and the pump shaft of impeller away from water intake side also arranges sub-propeller; O-ring seals I is provided with between described sheath and apron plate, O-ring seals II is provided with between described rear backplate and Gland, be provided with O-ring seals III between described sub-propeller 10 and axle sleeve, between described sub-propeller and impeller, be provided with O-ring seals IV.The utility model pump head adopts double pump shell structure, and intensity is high, and the shaft seal of pump have employed packing seal and sub-impeller seal pattern, also adopts O-ring seals at multiple key position in addition, substantially increases the sealability of pump; The utility model adopts high chrome molybdenum abrasion resistance alloy to manufacture flow passage components, has increased substantially the working life of Horizontal slurry pump.
Description
Technical field
The utility model relates to a kind of industrial pump being applicable to the industry conveying high concentrations such as metallurgy, mine, coal, thermal power plant, large particle slag slurry, in particular, relates to a kind of Horizontal slurry pump.
Background technique
All there is shaft sealing problem in Pulp pump and the slurry pump of current industrial and mineral extensive use, under normal circumstances, adopt the seal approach that three kinds common: packing seal, sub-impeller seal and mechanical seal, these three kinds of sealings can both play certain sealing effect, but, but there are some drawbacks respectively, as follows:
1, packing seal: if water seal underpressure, so will produce leakage in the short time, even if water seal pressure meets the demands, according to the information of user feedback, its working life is two to three moons at most.
2, sub-impeller seal: compare packing seal sub-impeller seal effect much better, but its complex structure, accessory are more, cost is expensive, according to the information of user feedback, about its half a year in working life.
3, mechanical seal: compare packing seal and sub-impeller seal effect is best, according to the information of user feedback, in about 1 year its working life, mechanical weakness is that cost is high.
Therefore, Pulp pump shaft sealing problem is a difficult problem for puzzlement industrial and mining enterprise always.The shaft sealing problem that can solve Pulp pump has very important practical meaning in engineering.
Summary of the invention
For the defect that Pulp pump sealing effect in prior art is bad, the technical problem to be solved in the present invention is to provide a kind of Horizontal slurry pump, can realize effective sealing equally, reduce costs simultaneously.
A kind of Horizontal slurry pump, comprise bearing housing, impeller, pump shaft, form by front pump cover, rear pump cover, apron plate, rear backplate, sheath the blade wheel chamber having double pump shell structure, pump shaft end is provided with impeller by impeller nut, and the pump shaft of impeller away from water intake side also arranges sub-propeller; O-ring seals I is provided with between described sheath and apron plate, O-ring seals II is provided with between described rear backplate and Gland, be provided with O-ring seals III between described sub-propeller 10 and axle sleeve, between described sub-propeller and impeller, be provided with O-ring seals IV; Axle sleeve on described pump shaft is also provided with adjusting sleeve and stripping ring near the side of bearing housing, described stripping ring and water dumping annular face contacts.
The utility model pump head adopts double pump shell structure, and intensity is high, and the shaft seal of pump have employed packing seal and sub-impeller seal pattern, also adopts O-ring seals at multiple key position in addition, substantially increases the sealability of pump; The utility model adopts high chrome molybdenum abrasion resistance alloy to manufacture flow passage components, and it has outstanding wear resistance, thus has increased substantially the working life of Horizontal slurry pump, reduces enterprise's user cost, brings larger economic benefit to enterprise.
