Abstract
The present invention relates to a series submersible motor which is characterized in that the series submersible motor comprises a plurality of stators respectively arranged in a plurality of casings connected by connecting segments, a plurality of corresponding rotors arranged in the stators, rotor shafts connected by cylinder shaft couplers, and a plurality of pairs of stator windings connected in series after wires are inserted respectively. Compared with the prior art, the series submersible motor has the advantages of large power, small diameter, high rotor rigidity for bearing larger axial force and radial force, etc., and can be used as matched dynamic force for minor-diameter submersible pumps for wells.
Description
The invention belongs to submersible electric motor art designs field, be specifically related to a kind of high-power series submersible electric motor.
In the prior art, submersible electric motor limits because of being subjected to hole diameter, and the big more motor unit of power is elongated, and rotor is elongated, causes the rotor poor rigidity, and processing difficulties is prone to and sweeps thorax, has limited the development of heavy-duty motor.As existing national Specification seat No. is that 200 submersible electric motor maximum power is 37 kilowatts.Yet the power that needs has limited the development of well with immersible pump more than big of existing product more.Foreign patent discloses a kind of scheme that several stators, rotor inline are got up, but, it be with several rotor hot chargings on an axle, can't change and keep in repair disadvantage such as thrust bearing inconvenience is installed and axial location is unadjustable after causing dismounting difficulty, guide bearing and axle wearing and tearing.Foreign patent also discloses the scheme that a kind of several stator winding can be connected, yet this scheme is to connect after several stator winding are drawn the motor exocoel, this scheme only is applicable to motor external diameter and the unrestricted universal motor of usage space, and is not suitable for the extraordinary submersible electric motor that the motor external diameter is subjected to strict restriction.
The present invention has overcome the deficiencies in the prior art part, and for the design high-lift submersible pump provides a kind of power big, diameter is little, can bear the power-equipment of larger axis to power.
The present invention be achieved in that series submersible electric motor comprise several stators of being contained in the casing and with corresponding several rotors of stator; Be contained in the thrust bearing in base and the connecting section and be contained in thrust collar corresponding on the armature spindle etc. with thrust bearing, also comprise several stator winding that are serially connected, it is characterized in that several stators are contained in several casings, casing is connected by the connecting section of band window.Several rotors are connected with corresponding armature spindle by the cartridge type shaft coupling.Some to the guidance axle by the guide shaft bearing by being bolted to the two ends of casing.Thrust bearing is adjusted axial location by screw thread and the adjustment double-screw bolt that is contained in the base, and what guarantee that thrust collar and thrust bearing are formed somely contacts simultaneously to friction pair, with the downward axial force of heeling pump.Last thrust bearing is contained in the lower end of guide bearing in the base, the axial force that makes progress during the heeling pump starting.This structure of the present invention has been broken the structural shape of a rotor of a stator of motor of traditional diving, overcome the shortcoming of above-mentioned prior art, realized multi-point radial supporting and the some multiple spot axially mounting to friction pair of several rotors, the radial load and the axial force of rotor that improved the rigidity of rotor and balance by guide bearing.
Series submersible electric motor of the present invention be with the adjacent winding terminal of several stator winding by lead wire in the wiring of submersible electric motor inner chamber serial connection.Several stator winding are communicated, identical with the electric current that reaches several stators, the purpose that rotating speed equates.This submersible electric motor is considered as a motor integral body to several stators and several rotors and carries out electromagnetism calculating when carrying out Electromagnetic Design, tries to achieve the best fit of each parameter of motor.
Description of drawings:
Fig. 1 is the series submersible electric motor structure principle chart.
Fig. 2 is the series submersible electric motor developed winding diagram.
Label declaration:
1, guide bearing 2,10, stator 3,11, rotor 4, lead wire 5, cartridge type shaft coupling 6,14, thrust collar 7,15, thrust bearing 13, last thrust bearing 8, connecting section 9, base 12, adjustment double-screw bolt 16, casing
With reference to the accompanying drawings embodiment is described further.Present embodiment is to be contained in respectively in two casings 16 with a pair of stator 2,10, and a pair of rotor 3,11 is contained in respectively forms series submersible electric motor in the corresponding stator 2,10.Two casings, 16 usefulness that are contained in stator 2,10 have connecting section 8 connections of window, and two stator winding difference rules are connected in series adjacent winding overhang leading-out terminal after the assembling by lead wire 4, and two rotors 3,11 are by 5 connections of cartridge type shaft coupling; The guide shaft bearing bolt at casing 16 two ends, guide bearing 1 is contained in the guide shaft bearing, makes serial connection rotor 3,11 form the multi-point radial supporting; Thrust shaft 15 is adjusted axial location by adjusting double-screw bolt 12.During assembling, will adjust double-screw bolt 12 earlier and down twist, the rotor 3,11 of will connect to pressing down, is close to thrust bearing 7 and thrust collar 6 by the shaft extension end, upwards twists and adjusts double-screw bolt 12, and thrust collar 14 and thrust bearing 15 are close to.Last thrust bearing 13 bears the upwards axial force of starting of pump station process, for guaranteeing thrust collar 14 and last thrust bearing 13 end play of 0.5-1 millimeter is arranged, and the axle of rotor 11 requires to be designed to plus tolerance.Accompanying drawing 2 is a submersible electric motor windings in series expanded view, connecting section 8 connects stator 2,10 o'clock, guarantee the wire casing alignment of two stators, earlier with stator 2,10 difference rules, after the assembling with stator 2,10 adjacent winding terminal is drawn the serial connection wiring by lead wire 4 from the window of connecting section 8, serial connection lead-in wire 4 well is behind connecting section 8 internal fixation, scuttle is screwed on, series submersible electric motor is two stators 2 when work, 10 will produce identical rotating magnetic field, make two rotors 3,11 run-in synchronisms, thrust bearing 7,15 and thrust collar 6,14 friction pairs of forming can bear the bigger axial force of water pump simultaneously, but the radial load during two pairs of guide bearing 1 bear rotor runnings and strengthened the rigidity of rotor.
Advantage of the present invention is: can bear bigger axial thrust, elongate rotor is realized the multi-point radial supporting, energy bear rotor radial load, rotor good rigidly; Can utilize existing submersible electric motor stator and rotor manufacturing; The set structure compactness, highly versatile can be made the submersible electric motor of high-power minor diameter.
