Abstract
The utility model relates to a submersible electric pump which belongs to the drainage and irrigation equipment, comprising an electrode and a water pump. The lower part of a motor is provided with the water pump, and the water pump is connected with the motor by a C screw. The motor adopts a shaft provided with a rotor and supported by a bearing arranged on an upper and a lower bearing seats which are arranged on a casing made of a thin plate. The stator of the motor is fixed by an upper and a lower linings. An end press plate which is clamped by a clamping spring is arranged above the upper bearing seat. The end press plate is provided with an A screw, and an external cover is fixed on the end press plate by a B screw. The utility model which has the advantages of simple structure, convenient manufacture, light weight, good heat dissipation, and long service life is suitable for the drainage and irrigation of various occasions.
Description
The utility model relates to a kind of Submerged Motor Pumps, belongs to drainage and irrigation equipment, is suitable for the usefulness of industrial and agricultural production and life irrigation and drainage.
Present used Submerged Motor Pumps, motor stator adopts radially fixing, promptly radially fixing with clamp-screw or employing interference fit, thereby require motor housing that thicker wall thickness is arranged, this has not only increased the weight of the weight of motor, and causes heat radiation bad and influence electrical machinery life, simultaneously, because of set screw place sealing difficulty, easily cause infiltration and burn out motor.Up to now, have no precedent simple in structure, in light weight, the Submerged Motor Pumps of good heat dissipation.
It is heavier that the purpose of this utility model is to overcome existing Submerged Motor Pumps weight, the bad deficiency of dispelling the heat, thus a kind of Submerged Motor Pumps is provided, it simple in structure, in light weight, good heat dissipation, long service life is suitable for the usefulness of industrial and agricultural production and irrigation and drainage in life.
The purpose of this utility model realizes by following approach:
The utility model comprises motor and water pump two-part, is provided with water pump in the bottom of motor, is connected with the step of motor with the water inlet joint of C screw with water pump.Said motor is that set upper bearing bracket and the bearing on the step of correct position supporting the axle that is fixed with rotor in the enclosure, lining was fixed under set stator was reached by lining on suitable outside rotor, above upper bearing bracket, be provided with end clamp plate by jump ring card jail, be provided with the A screw at the end clamp plate correct position, use the B screw on end clamp plate enclosing cover again.Said shell is made with thin plate, in the roll extrusion of shell correct position two muscle is arranged, and is provided with jump ring in the muscle.Said water pump can be centrifugal pump or Vortex pump or partial emission pump or goes up pump formula or suction booster or multistage pump.
Figure is the utility model one-stage centrifugal Submerged Motor Pumps embodiment's a structural representation, wherein: 1-enclosing cover, 2-B screw, 3-jump ring, the 4-end clamp plate, 5-A screw, 6-upper bearing bracket, the last lining of 7-, the 8-shell, 9-stator, 10-rotor, 11-bearing, 12-step, the 13-joint of intaking, 14-volute, 15-impeller, the 16-bottom, lining under the 17-, 18-motor, 19-water pump, the 20-C screw, 21-muscle, 22-axle.
Embodiment describes in detail below in conjunction with accompanying drawing:
The utility model embodiment includes motor 18 and centrifugal pump 19 two-part, is provided with centrifugal pump 19 in the bottom of motor 18, is connected with the step 12 of motor 18 with the C screw 20 water inlet joint 13 with centrifugal pump 19.Said motor 18 is that upper bearing bracket 6 and the bearing 11 on the step 12 set in shell 8 supporting the axle 22 that is fixed with rotor 10, outside rotor 10 set stator 9 by on lining 7 and down lining 17 fixed, above upper bearing bracket 6, be provided with end clamp plate 4 by jump ring 3 card jails, on end clamp plate 4, be provided with A screw 5, again enclosing cover 1 usefulness B screw 2 be fixed on the end clamp plate 4.Said shell 8 usefulness sheet metals are made, roll extrusion has two muscle 21 on shell 8, be provided with jump ring 3 in the muscle 21, as the hard point of whole axial compression, in the axial direction with A screw 5 by end clamp plate 4, upper bearing bracket 6, go up lining 7, lining 17 and step 12 are fixing with stator 9 down.
The utility model contrast prior art has following advantage:
1, the utility model is simple in structure, and is easily manufactured;
2, the utility model is owing to the measure of taking the axial restraint stator, so that shell 8 can be adopted Make with thin plate, therefore in light weight, good heat dissipation effect, the life-span is long, and cost is low;
3, the utility model can be according to using needs, and the volute 14 of the used water pump 19 of conversion, impeller 15, bottom 16 can change lift and flow, use very economical.
