Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of centrifugal pump, particularly a kind of centrifugal pump impeller.
Background technique
Centrifugal pump utilizes vane rotary and makes water generation centrifugal motion carry out work, and what the essential structure of centrifugal pump was made up of six parts is impeller respectively, the pump housing, pump shaft, bearing, seal ring, stuffing box.Impeller is the core of centrifugal pump, and its rotating speed high output is large, and the blade on impeller plays Main Function again, and impeller will be tested by static balancing before assembly.Inner and outer surface on impeller requires smooth, to reduce the frictional loss of current.The pump housing also claims pump case, and it is the main body of water pump.Play support fixation, and be connected with bearings mounted bracket.The effect of pump shaft borrows coupling to be connected with motor, and impeller is passed in the torque of motor, so it is the critical piece transmitting mechanical energy.Bearing uses clean oil to make oiling agent, refuels oil level line, and too many oil will ooze out along pump shaft, very little bearing again overheated burning out cause the accident.The highest at 85 degree in the temperature of water pump operation process middle (center) bearing, generally operate in about 60 degree.Before activation, must make to be full of water, then starting electrical machinery in pump case and water suction shell, make pump shaft impeller and water do high speed rotary motion, water generation centrifugal motion is thrown toward impeller outer edge to centrifugal pump, and the runner through volute pump case flows into the setting-out pipeline of water pump.
At present in order to improve setting pressure, gather together two or more pumps of said function formation multistage centrifugal pump, the impeller of multistage centrifugal pump adopts single entry casting impeller to coordinate axle sleeve to be cascaded, such assembling location inconvenience, installation precision is low, stability between impeller at different levels is not high, affect the hydraulic performance of centrifugal pump, also have the Impeller Mass of casting heavier, easily sand is amassed in the cavity that impeller internal exists, not easy to clean, when causing assembling, sand comes off, and can abrade impeller endoporus and pump shaft surface.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides the centrifugal pump impeller of a kind of compact structure, easy to assembly and long service life.
The purpose of this utility model realizes by following technical proposal: a kind of centrifugal pump impeller, it is characterized in that, comprise blade, base plate and tubular wheel hub, in the middle part of described hub periphery, there is position structure, described base plate offers center hole, the center hole edge of described base plate is positioned position structure and welds mutually with hub periphery, described blade is welded on base plate, described wheel hub is welded with the cover plate hidden by blade, described blade, base plate, wheel hub and cover plate are stainless steel punching press sheet metal part.
Each part of this centrifugal pump impeller is stainless steel metal plate punching part, possesses good decay resistance, long service life, and adopt laser bonding to form, structure is merrily and lightheartedly firm, work efficiency is high, the position structure of wheel hub ensure that the positioning precision of base plate in addition, instead of single entry impeller in the past and adds the assembling mode of axle sleeve, and assembling and positioning is convenient, angle, the radian of blade can accurately control, and can ensure that centrifugal pump has good hydraulic performance like this.
In above-mentioned centrifugal pump impeller, described position structure be the loop had in the middle part of hub periphery and protrude positioning seat, the center hole edge of described base plate contacts at positioning seat and locates.
As another kind of situation, in above-mentioned centrifugal pump impeller, described position structure is the recessed locating slot of the circle that has in the middle part of hub periphery, and the center hole edge of described base plate to be embedded in locating slot and to locate.
In above-mentioned centrifugal pump impeller, the center hole edge of described base plate is flange shape.Which increase the area of contact with wheel hub, after welding, structural integrity is good.
In above-mentioned centrifugal pump impeller, described base plate has the anti-radian section of close center hole.Which increase base plate strength.
Compared with prior art, it is merrily and lightheartedly firm, easy to assembly that this centrifugal pump impeller has structure, the advantage of work efficiency height and long service life.
