Description
One, technical field
The utility model relates to a kind of drainage power device, particularly relates to a kind of structure with reinforcement electric pump stator radial rigidity.
Two, background technology
Full through-flow submersible pump is a kind of drainage equipment water pump vane being placed in diving generator rotor inner chamber, is subject to the restriction of water pump vane diameter, and therefore the motor stator and rotor cylindrical of full through-flow submersible pump is more much larger than general common electric machine.When carrying out large-scale full-tubular pit submersible motor design, as stator punching external diameter be 2100mm time, usual stator yoke height dimension just can meet motor electromagnetic designing requirement less than 100mm, but the too small meeting of height dimension of yoke portion makes the radial rigidity of stator core very poor, the radial magnetic pull effect be subject in motor operation course, be easy to produce stator core radial deformation, cause stator and rotor to wipe mutually, cause the serious accident of burn-down of electric motor.The method of ordinary solution determinant iron core insufficient rigidity is the yoke portion height dimension of expanded motor stator punching, in order to meet rigidity requirement, the required yoke portion height dimension increased is 2-3 times of reasonable yoke portion height dimension, this method can cause the overall dimension of full-tubular pump motor very huge, and consumptive material is many, weight is large, and the effective rate of utilization of material reduces.
In order to the problem of the stator radial rigidity difference that the large cylindrical little yoke portion size solving full-tubular submersible motor stator causes, this patent provides a kind of new construction design method, well ensure that the radial rigidity requirement of stator core, improve the stock utilization of stator iron core silicon steel sheet simultaneously, decrease material usage, reduce the complete machine weight of full-tubular pump.
Three, utility model content
In order to overcome the weak point of existing drainage power device, the utility model provides a kind of structure with reinforcement electric pump stator radial rigidity.
The technical solution of the utility model realizes like this.
The a kind of of this programme has the structure strengthening electric pump stator radial rigidity, comprise support and trim ring, stator core is provided with in described support, the support of cylindrical residing for this stator core is provided with some ring muscle, described support two ends are provided with end flanges, are along the circumferential direction evenly provided with some first radial rib between any described end flanges and ring muscle; Along the circumferential direction evenly be provided with some second radial rib between any described ring muscle and support, between any described the second adjacent radial rib, be along the circumferential direction evenly provided with some holes with the support surface of stator core contact position; Described stator core two ends are compressed by trim ring, described trim ring edge be along the circumferential direction evenly provided with some with hole with the use of groove; By slot welding being connect, stator core is fixedly connected with trim ring; By groove is alignd with hole, hole is welded, the groove passing hole that support and stator core are arranged is welded, thus stator core is fixedly connected with support.
Described ring muscle number is individual.
Described groove is identical with hole number.
Described groove sealing weld weld seam in line, makes stator core be fixedly connected with trim ring.
By being alignd with hole by groove, plug welding being carried out to hole, the groove passing hole that support and stator core are arranged being welded, thus stator core is fixedly connected with support.
Usefulness of the present utility model is: this device structure is simple, strengthen the rigidity of stator core, avoid the stator and rotor occurring to cause because of motor stator core distortion to wipe phenomenon mutually, effectively extend the useful life of motor, decrease material usage, reduce the complete machine weight of full-tubular pump.
Four, accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
A kind of structure with reinforcement electric pump stator radial rigidity as shown in the figure, comprise support 1 and trim ring 6, stator core 2 is provided with in described support 1, the support 1 of cylindrical residing for this stator core 2 is provided with some ring muscle 3, described support 1 two ends are provided with end flanges 9, are along the circumferential direction evenly provided with some first radial rib 7 between any described end flanges 9 and ring muscle 3; Along the circumferential direction evenly be provided with some second radial rib 8 between any described ring muscle 3 and support 1, between any described the second adjacent radial rib 8, be along the circumferential direction evenly provided with some holes 4 with support 1 surface of stator core 2 contact position; Described stator core 2 two ends are compressed by trim ring 6, described trim ring 6 edge be along the circumferential direction evenly provided with some with hole 4 with the use of groove 5; By making stator core 2 be fixedly connected with trim ring 6 groove 5 welding; By groove 5 is alignd with hole 4, hole 4 is welded, groove 5 passing hole 4 that support 1 and stator core 2 are arranged is welded, thus stator core 2 is fixedly connected with support 1.
Described ring muscle 3 number is 2.
Described groove 5 is identical with hole 4 number.
Described groove 5 sealing weld weld seam in line, makes stator core 2 be fixedly connected with trim ring 6.
By being alignd with hole 4 by groove 5, plug welding being carried out to hole 4, groove 5 passing hole 4 that support 1 and stator core 2 are arranged being welded, thus stator core 2 is fixedly connected with support 1.
The course of work of this example: stator core 2 and trim ring 6 integral installation are assigned in support 1, ensure that groove 5 weld seam circumferentially aligns in uniform hole 4 with support 1, circumferentially hole 4 is carried out by plug welding to support 1, make to weld between the groove 5 weld seam passing hole 4 on stator core 2 and support 1, thus make stator core 2 and support 1 in aggregates, strengthen the rigidity of stator core.
After this patent is applied on the full through-flow submersible pump products such as QGWZ700, QGWZ900, QGWZ1000, QGWZ1200, QGWZ1400, stator core 2 rigidity is effectively strengthened, and the stator and rotor not occurring to cause because motor stator core 2 is out of shape wipe phenomenon mutually.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
