Description
Technical field
The utility model belongs to the pump technology field, especially relates to a kind of water pump vane.
Background technique
Existing water pump vane mainly adopts casting of metals such as iron and steel, copper to be shaped, and surface treatment is carried out in machining, and not only metal wastage is big, the cost height, and use comparatively heavy.Because the impeller long-term work is under liquid environment, the surface gets rusty easily, and causes impeller shortening in working life.Particularly in working long hours, cavitation effect meeting makes the surface fatigue damage gradually of metallic material, causes degrading of metal surface, and then big or small cellular scoring occurs.Except impact causes the damage of metal parts, also be attended by the effect of multiple complexity such as electrolysis, chemical corrosion.The instability of cavitation process causes water pump generation vibration and noise, because the energy interchange of impeller and liquid is interfered and destroys, the flow of pump, lift, efficient, shaft power curve descend, and can make liquid interruption in the pump when serious, the water pump cisco unity malfunction.In order to prevent cavitation, several measures below adopting usually in the mechanism of water pump: 1, adopt double-entry impeller; 2, increase the impeller eye area; 3, increase the entrance edge of blade width; 4, increase impeller front and rear cover plate turning radius of curvature; 5, entrance edge of blade extends to the suction side; 6, the impeller chopped-off head adopts the anti-cavitation material; 7, establish preposition inducer.Though these measures can the decreasing cavitation effect, can not fundamentally solve the cavitation problem.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of high-speed water impeller, and this product not only cost is low, and has excellent anti cavitation performance, antirust, light weight and be connected not easy to wear with axle.
The technical solution of the utility model is as follows: a kind of high-speed water impeller, comprise impeller bodies, this impeller bodies has center hole, described impeller bodies both ends of the surface respectively have an axial round ring boss, one side is the major diameter boss, one side is the minor diameter boss, on the end face that the minor diameter boss is arranged by being evenly distributed in blade, its key is: described impeller bodies and blade are by polyamide (being commonly called as nylon) material while injection molded, in the center hole of described impeller bodies, be installed with metal axle sleeve, this axle sleeve center has axis hole, described axle sleeve is divided into enlarged diameter section and reduced diameter section, major diameter boss equal diameters on the outside diameter of enlarged diameter section and the described impeller bodies wherein, and be positioned at the outside of described major diameter boss, described axle sleeve reduced diameter section stretches in the center hole of described water pump vane.
Adopt above technological scheme, because nylon has very high mechanical strength, the softening point height, heat-resisting, friction ractor is low, and is wear-resistant, self lubricity, shock absorption and noise reduction, corrosion resistant performance, chemical-resistance are good; When guaranteeing turbomachine performance, do not produce cavitation phenomenons in the using process, thereby guarantee the working efficiency of water pump.And nylon belongs to engineering plastics, compares metal qualities such as iron and steel, copper and obviously alleviates.
Described high-speed water impeller, described impeller bodies is injection-moulded on the described axle sleeve.Nylon material directly is injected on the axle sleeve, impeller bodies and axle sleeve are fastenedly connected, when axle rotates, drive water pump vane by axle sleeve and rotate.
Described high-speed water impeller is provided with internal thread in the front portion of described axle sleeve reduced diameter section.Impeller must be connected and rotates with axle with axle by axle sleeve, therefore axle sleeve wearing and tearing can occur with the face that touches that is coupling, though nylon material also has wear resistance preferably, but has better wear resistance with respect to the nylon material metal, therefore, on impeller body, connect a metal axle sleeve, this metal axle sleeve is matched with axle, thereby prolonged the life-span of impeller greatly.
Described high-speed water impeller, the exterior edge face of described axle sleeve enlarged diameter section has toroidal cavity, can alleviate the weight of axle sleeve, thereby alleviates the weight of whole water pump vane.
The beneficial effects of the utility model are: the long-time use of the utility model does not produce cavitation phenomenons, and corrosion resistance is good.Compare with the iron and steel impeller, quality alleviates greatly, and rotational noise is low, the pump efficiency height.The utility model adopts the nylon material injection molded, has significantly reduced manufacturing procedure, has effectively improved labour productivity, the conformity that can effectively improve the quality of products simultaneously.On impeller bodies, connect metal axle sleeve, reduced the wearing and tearing of impeller, further prolonged the working life of impeller.The application of whole model utility obviously reduces manufacture cost, and productivity effect improves.
