Abstract
The invention discloses a sewage pump impeller. The impeller comprises an impeller body which is prepared from wearable plastic; the impeller body comprises a disc-shaped base, and a blade which is arranged on the surface of one side of a base; a metal supporting plate for improving the rigidity of the impeller is wrapped with the base. According to the sewage pump impeller, the impeller body prepared from the wearable plastic and the metal supporting plate arranged in the impeller base bring the impeller the characteristics of being flexible in outside and hard in inside, and therefore, the impact resistance and wearable performance of impeller can be effectively improved; a sewage pump can effectively work normally for a long term in a underwater environment containing sand, sludge and other impurities, and the problem that the impeller is damaged and the machine is stopped to replace the damaged impeller can be avoided.
Description
Technical field
The present invention relates to waste removal equipment field, be specifically related to a kind of sewage pump impeller.
Background technique
Sewage pump is widely used in the environment such as building industry, sewage water discharge engineering, mining engineering, usually containing the foreign material such as sandstone, mud in this type of ambient water.Existing sewage pump impeller material is generally rigid plastics, and when sewage pump runs up, in water, foreign material are under rigid plastics impeller action outside excavationg pump.In discharge process, the foreign material repeat impact in water scrapes rigid plastics impeller, because self impact resistance of rigid plastics impeller is poor with touching, bear repeat impact and touching when scraping, easily cause damage in impeller, reduce pump performance, need irregularly to change impeller, add user cost.
Summary of the invention
The object of the present invention is to provide a kind of strong shock resistance, anti abrasive sewage pump impeller.
The technical solution adopted in the present invention is mainly: a kind of sewage pump impeller, comprise the impeller bodies be made up of wear-resistant plastic, described impeller bodies is made up of discoid pedestal and the blade being arranged on pedestal one side surface, described base central is provided with the through hole connecting motor output shaft, described base interior is coated with metallic support sheet, the through hole of the corresponding pedestal in described metallic support sheet center offers center hole, impeller has outer soft interior hard feature, effectively enhance the shock resistance of impeller and anti abrasive ability, transmit the torsion that is subject to of impeller by metallic support sheet simultaneously, strengthen the ability of the counter-bending distortion of impeller.
As the improvement of technique scheme, described metallic support sheet center hole periphery is distributed with multiple reinforced hole in order, makes the connection of metallic support sheet and pedestal more firm.
As the further improvement of technique scheme, described metallic support sheet material is corrosion resistant plate, corrosion resistant plate can plastics in pedestal outside damaged time, whole impeller will be caused to lose efficacy rapidly because metallic support sheet contact water environment is got rusty.
Further, described impeller bodies material is TPU flexible plastic, enhances wear resistance and the impact resistance of impeller.
The invention has the beneficial effects as follows:
A kind of sewage pump impeller of the present invention, comprise the impeller bodies be made up of wear-resistant plastic, impeller bodies is made up of discoid pedestal and the blade being arranged at pedestal one side surface, base central is provided with the through hole connecting motor output shaft, base interior is coated with the metallic support sheet for strengthening impeller rigidity, the wear-resistant plastic impeller bodies made and the metallic support sheet being arranged on impeller base interior, impeller is made to have outer soft interior hard feature, effectively enhance the shock resistance of impeller and anti abrasive ability, thus containing sandstone, in the underwater environment of the foreign material such as mud, the long-term normal work of effective guarantee sewage pump, the frequent shutdown because of impeller failure is avoided to change impeller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
With reference to Fig. 1, a kind of sewage pump impeller of the present invention, comprise the impeller bodies 1 that wear-resistant plastic is made, described wear-resistant plastic is preferably TPU flexible plastic, the impeller bodies 1 that TPU flexible plastic is made has wear-resisting, bearing capacity is strong, the advantages such as impact resistance and damping performance are outstanding, impeller bodies 1 is made up of with the blade 11 being arranged at pedestal 10 1 side surface discoid pedestal 10, pedestal 10 center is provided with the through hole connecting motor output shaft, pedestal 10 inside is also coated with the metallic support sheet 2 for strengthening impeller rigidity, thus make impeller have outer soft interior hard feature, effectively enhance the shock resistance of impeller and anti abrasive ability, the through hole of the corresponding pedestal 10 in metallic support sheet 2 center offers center hole 20, thus the torsion making metallic support sheet 2 bear impeller to be subject to, enhance the ability of the counter-bending distortion of impeller.Metallic support sheet 2 is preferably corrosion resistant plate and makes, and corrosion resistant plate has certain rigidity, and rustless property is good simultaneously, is adapted at the medium-term and long-term use of underwater environment.
Inner in order to metallic support sheet 2 being arranged on securely pedestal 10, multiple reinforced holes 21 of distribution are in order made at metallic support sheet 2 center hole 20 periphery, pedestal 10 is when shaping by modes such as injecting glues, the reinforced hole 21 of metallic support sheet 2 also can be filled up by plastics, thus metallic support sheet 2 and pedestal 10 are closely connected as a single entity, transmit torsion better and not easily loosen, the setting of reinforced hole 21 simultaneously also makes metallic support sheet 2 be unlikely to overweight and cause the more powerful motor of impeller operation needs, reduces user cost.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, as long as the technological scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
