Abstract
The invention discloses an efficient energy-saving water pump blade. A water passing groove is formed in the middle of a water pump blade body, meanwhile a certain side inclination angle is formed on the face of the water pump blade body, and the middle end of the blade body tilts upwards. According to the design, it can be guaranteed that when the blade body rotates at a high speed, the integral resistance of water to the blade body is reduced, and the water pumping efficiency of a water pump is improved. Compared with an ordinary blade, the water pump blade is efficient, capable of saving energy, long in service life and capable of reducing the negative-pressure resistance borne by the blade body when circulation water enters a blade cavity, the risk of root or blade fracture in the continuous blade working process is reduced, and the efficient energy-saving water pump blade is suitable for mass actual production application of water pump manufactures.
Description
Technical field
The present invention relates to a kind of water pump accessory, specifically belong to a kind of energy-efficient water pump blade.
Background technique
Impeller is the core component of water pump, the major effect element of working efficiency. under specific operation, if Impeller Design is bad will produce hydraulic loss and gap loss at pump intake and blade place. the equally distributed blade on axle bed that traditional water pump blade is all is axle center with water pump axle bed, reaches the effect of drawing water by the rotation of blade in water pump cover.But the weight due to blade is equally distributed, when pump up water liquid, efficiency is not high, and the pumping for water pump efficiency that therefore conventional impellers is housed is lower.
Summary of the invention
The object of the invention is to provide a kind of energy-efficient water pump blade, solves the problem that water pump blade is energy-efficient, reasonable in design.
The technical solution used in the present invention is as follows:
A kind of energy-efficient water pump blade, the intermediate portion of water pump blade had tank, and blade is unilateral simultaneously has certain side rake, and the middle-end of blade upwarps.When this design can ensure this kind of blade high speed rotating, reduce water to the overall resistance of blade, reduce after circulating water enters blade cavity, the negative pressure pressure that blade bears, reduces blade in continuous operation process, occurs that root splits or the risk of part.
Described blade is back curved, meander configuration blade, and the central angle number of degrees of blade skew back part are 22 °, and the angle of blade middle-end upturned portion is 5 °, and radius is upwarp the crow flight distance of end to root of blade.
The material of described blade is casting brass, and wherein copper content is not less than 35%, and Theil indices is not more than 62%, in addition containing zinc, aluminium, strontium, magnesium.
Described blade intermediate portion has through hole and crosses tank, and shape is consistent with impeller outer profile, wide 5mm, and long 50mm has the effect of flow-disturbing, can eliminate water pump running hours, the turbulent flow in circulating water and blade cavity and advection dead angle.
Compared with the prior art, beneficial effect of the present invention is as follows:
Compared with common blade, this water pump blade has: energy-efficient, long service life, and can reduce after circulating water enters blade cavity, the negative pressure resistance that blade bears, reduces blade in continuous operation process, occurs that root splits or the risk of part.Be applicable to water pump producer production application in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the positive schematic diagram of structure of the present invention;
Fig. 2 is structure side schematic diagram of the present invention.
Embodiment
See accompanying drawing, a kind of energy-efficient water pump blade, tank 2 was had at the center of water pump blade 1, resistance is reduced when wheel rotation, current can be passed through, improve the efficiency of drawing water of water pump, after this Efficient water pump blade of the supporting replacing of traditional water pump, the ability of water pump pump up water liquid can be improved, reduce energy consumption.Described impeller 1 is back curved, meander configuration blade, and material is brass.Described impeller central crosses tank 2, and shape is consistent with impeller outer profile, wide 7mm, long 50mm.During this pump working, can reduce after circulating water enters blade cavity, the negative pressure resistance that blade bears, reduces blade in continuous operation process, occurs that root splits or the risk of part.Energy-efficient, long service life, is applicable to water pump producer production application in enormous quantities.
