Abstract
The invention relates to an impeller, and belongs to the technical field of water pump accessories. The impeller comprises a hub, and at least three blades arranged on the periphery of the hub in a surrounding manner, wherein the edge of each of the blades in the rotating direction of the impeller and the top end edge of each of the blades take a saw-toothed shape; the surface of each of the blades is coated by a frosted layer; the impeller is made of polyacrylonitrile carbon fiber. During operation, the impeller can cut and smash the foreign matters sucked by a water pump so as to prevent the water pump from being blocked, and moreover, as the weight of the impeller is only 40% of that of the ordinary impeller, the driving energy is saved.
Description
Technical field
The present invention relates to a kind of impeller, belong to water pump accessory technical field.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.Water pump is mainly made up of pump case, pump cover, pump shaft, impeller and sealing system.Because the operating conditions of water pump is badly assorted again, often have foreign matter and block, cause water pump to shut down, need to take cleaning apart, lose time and energy.
Summary of the invention
The technical problem to be solved in the present invention is, for prior art deficiency, proposes a kind of quality light and can cut and grind foreign matter, not only saved the energy but also can prevent the impeller of water pump card machine.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of impeller, at least three blades that comprise wheel hub and arrange around wheel hub periphery, the vane rotary direction edge of described blade and tip edge are flexuose, described blade surface is coated with frosted layer, and described impeller adopts polyacrylonitrile carbon fiber to make.
The improvement of technique scheme is: described blade and wheel hub joint are provided with strengthening rib.
The improvement of technique scheme is: the abrasive material of the frosted layer of described blade is brown corundum and black silicon carbide, the mass mixings such as described brown corundum and black silicon carbide.
The improvement of technique scheme is: the bonding agent of the frosted layer of described blade is resin.
The present invention adopts the beneficial effect of technique scheme to be: 1) make because impeller adopts polyacrylonitrile carbon fiber, total quality alleviates greatly, during for water pump, has saved driving force, thereby has saved energy; 2) because sense of rotation edge and the tip edge of impeller are flexuose, when work, can cut the foreign matter that water pump sucks, prevent card machine; 3), because blade surface is coated with frosted layer, the foreign matter that some water pumps can be sucked grinds, and makes the anti-card machine better effects if of impeller; 4) be high carbon steel because impeller uses material, adopt punching press integral forming process, make the bulk strength of impeller higher; 5) because the abrasive material of the frosted layer of blade is brown corundum and black silicon carbide, so the hardness of frosted layer is high, good toughness, low price, has good thermal conductivity; 6), because the bonding agent of frosted layer is resin, intensity is high, elasticity is large, shock-resistant.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of embodiment of the present invention impeller.
Embodiment
Embodiment
It is polyacrylonitrile carbon fiber that the impeller of the present embodiment uses material.Eight blades 2 that this impeller comprises as shown in Figure 1 wheel hub 1 and arranges around wheel hub periphery, blade 2 is provided with strengthening rib 3 with wheel hub 1 joint.Vane rotary direction edge and the tip edge of blade 2 are made as flexuose, and blade 2 surface-coateds have frosted layer.The abrasive material of the frosted layer of blade 2 is the mass mixings such as brown corundum and black silicon carbide, brown corundum and black silicon carbide, is coated on the surface of blade 2 by resinoid bond.The grain size number of palm fibre corundum and black silicon carbide is between 25#～30#.
Make because impeller adopts polyacrylonitrile carbon fiber, total quality alleviates greatly, during for water pump, has saved driving force, thereby has saved energy; Because sense of rotation edge and the tip edge of impeller are flexuose, when work, can cut the foreign matter that water pump sucks, prevent card machine; Because blade surface is coated with frosted layer, the foreign matter that some water pumps can be sucked grinds, and makes the anti-card machine better effects if of impeller; Because the abrasive material of the frosted layer of blade is brown corundum and black silicon carbide, so the hardness of frosted layer is high, good toughness, low price, has good thermal conductivity; Because the bonding agent of frosted layer is resin, intensity is high, elasticity is large, shock-resistant.
The present invention is not limited to above-described embodiment.All employings are equal to replaces the technological scheme forming, and all drops on the protection domain of requirement of the present invention.
Claims (4)
