Abstract
The new type axial-flow pump consists of power machine external shell, stator core and winding, rotor core and asynchronous squirrel-cage winding, hollow cylinder shaft, helical blades, bearings, front and back end covers, sealing device and locking device. As compared with existent technology, its structure is compact, manufacturing process is simple, and can save raw material, and its structure design in reasonable, so that it possesses the advantages of implementing electromechanical integration, extensive application and economizing electric energy, etc..
Description
The present invention relates to a kind of axial-flow pump.
At present, be divided into three major types substantially as the pump class of carrying liquid.A kind of is the centrifugal pump class, and a kind of is the axial-flow pump class, and another is the plunger pump class.The centrifugal pump class is by motor, pump, forms wheel and pump seat four parts, and motor reel and pump shaft are by to the wheel connection, and motor and pump all are installed on the pump seat or respectively and are installed on the basis.It is to rely on the diameter of liquid wheel entrance and exit of pump poor, when the rotation of liquid wheel, liquid is sucked the centrifugal principle of throwing out from outlet again from inlet, reaches the purpose of conveying.Current, the axial-flow pump class has three kinds of structures, a kind of similar centrifugal pump structure; A kind of wheel hub (as the ZDB series axis flow pattern submersible pump of the heavy submersible pump in Hefei factory production) that wing blades is arranged at motor reel output terminal mounting strap; Another is that screw type blade (as deep-well pump) is installed on the major axis of pump.These three kinds of structures all can realize liquid axial flow in pump case.Plunger pump is by piston to-and-fro motion in cylinder body, and with suction, the valve body is organic cooperates, suck from inlet to discharge from outlet again.Base for post pump majority is used in the strong lubricating system of equipment.Above-mentioned pump class substantially all is the pump housing and motor are made two body structures and to assemble together, and only ZDB series axis flow pattern submersible pump is at electric drive axle output terminal mounting strap wing blades one-level liquid wheel to be arranged, and its motor also is installed within the pump case.Existing axial-flow pump class formation complexity uses material many, cost cost height.
The objective of the invention is: design a kind of simple in structurely, motor and pump are the axial-flow pump of one.
Technological scheme of the present invention is, motor rotor shaft is made hollow cylindrical, two to three (or four) are " S " " Y " (or "+") type and have that the blade of spiral angle is uniform to cooperate solid welding with hollow cylinder axle inner diameter wall, hollow cylinder axle external diameter middle part assemble rotor iron core adopts asynchronous squirrel-cage winding to constitute rotor.Stator adopts single-phase repeatedly winding or three-phase two repeatedly winding, stator iron core and shells to be assembled into one.Ring in hollow cylinder axle external diameter two ends dress cylinder type bearing and the thrust-bearing, outer race is assembled in the front and rear cover seam, and front and rear cover is fixed by seam and shell fitted bolt.Be assembled with seal arrangement between front and rear cover endoporus and the hollow cylinder axle two ends external diameter.
The present invention can be designed to the hollow cylinder different inner diameters according to the different requirements of flow and lift, different length and different electromotor series, different capacity, the axial-flow pump of different electric pressures.The reverse butt joint of axial-flow pump more than two can constitute the multistage axial flow pump, and it can replace the band pump, can be made into vacuum self priming pump, pipeline pump, submersible pump and pollution discharge pump.
The present invention compared with the prior art, its advantage is: compact structure, simplified manufacturing process, realized electromechanical integration, electric electromechanics magnetic force radius is greater than helical blade mean resistance radius, and electric electromechanics magnetic force reduces more than 40 percent, thereby power demand is low, and it is little to consume energy, and purposes is wide.
Description of drawings:
Fig. 1 looks sketch for a kind of axial-flow pump structure master;
Fig. 2 is a kind of axial-flow pump side-looking sketch.
Most preferred embodiment of the present invention is: motor rotor hollow cylinder profile shaft 2 inner diameter wall are with uniform two to three (or four) are individual is " S " and " Y " (or "+") type helical blade 1 and cooperates solid welding, hollow cylinder profile shaft 2 external diameters middle part is integral with the rotor iron core 9 of asynchronous squirrel-cage winding construction, ring in hollow cylinder profile shaft external diameter two ends assembling cylinder type bearing 6 and the thrust-bearing 10, the outer shroud of cylinder type bearing 6 and thrust-bearing 10 is contained in front and rear cover 5 and 11 seams, front and rear cover 5 and 11 and shell 7 seam fitted bolts fix, assembled seal 4 and 12 between front and rear cover 5 and 11 endoporus and the rotor hollow cylinder axle 2 two ends external diameters, seal arrangement 4 and 12 front and rear cover 5 and 11 and the sealability of hollow cylinder axle by locking device 3 and 13 lockings.During work, when single-phase or three phase windings are connected power supply when motor stator 8, produce rotating magnetic field, the asynchronous cage winding of rotor iron core 9 produces induction current, induction field and electromagnetic force, rotor iron core 9 and hollow cylinder axle 2 rotate with asynchronous revolution, and assembly welding produces end thrust at the helical blade 1 of hollow cylinder axle 2 inner diameter wall, and liquid is sucked from the axial-flow pump rear end, axially release from front end, realize axially carrying the purpose of liquid.
