Abstract
The utility model relates to an energy-saving small-sized single-phase motor for a submersible pump, which comprises a main winding distributed in a stator slot of a motor, wherein the main winding is composed of five sets of coils. A starting coil is composed of three sets of coils which are respectively distributed in the stator slot; a centrifugal switch connected in series to the starting coil which is then arranged on a rotor shaft. The utility model can automatically close the starting coil, can enhance the running performance and can extend the service life.
Description
The utility model relates to a kind of immersible pump, is the immersible pump motor specifically, mainly is that the structure of motor has been done improvement.
At present, the immersible pump single-phase AC motor mostly is the shaded-pole single-phase AC motor by start mode.The shadedpole motor starting structure is to be sleeved on two short-circuited conducting sleeves are set on the stator main winding salient pole, does not disconnect all the time behind this two short-circuited conducting sleeves prestart.Because of shaded pole motor because operating current is higher, so its temperature rise also than higher, thereby influence useful life of submersible pump.
The purpose of this utility model provides a kind of simple in structure, reliable working performance, raising single-phase immersible pump motor in useful life that has.
For achieving the above object, technical solution of the present utility model is finished like this: it has the main winding that adopts motor is that 5 groups of coils and actuating coil are that 3 groups of coils are formed, and be distributed in respectively in the stator slot, by series connection one centrifugal switch on the actuating coil, and be installed in the rotor roller.
The utility model is total compared to existing technology as effect:
1, sees Table 1
| Model | Measured discharge M/H | Actual measurement lift M | Input power KW | Unit efficiency % |
| QDS5.5-18-0.75 (the existing motor of employing) | ?5.88 | ?19.24 | ?1.89 | ?16.33 |
| ?QDS5.5-18-0.75 | ?6 | ?19.5 | ?1.208 | ?26 |
As can be seen from Table 1, the more original technology on behavior in service of the motor after the improvement is greatly improved and is improved.
2, have the actuating coil of employing and connect, behind certain rotating speed, disconnect voluntarily in electrical motors with centrifugal switch.Actuating coil no longer works, and guarantees that main winding and cage-type rotor carry out Conversion of energy.
3, changed motor starting system, reduced operating current and temperature rise, made complete machine improve useful life.
Embodiment is to the concrete description of this novel do in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of motor.
Fig. 2 is motor pitch and number of turn distribution map.
Show the structure of energy-conservation small-sized single-phase immersible pump motor by Fig. 1,2.Groove number with employing stator 4 is 24 grooves, its main winding 1 adopts the positive chorded winding method of salary distribution, and main winding 1 is made up of 5 groups of coils (one side of something), is distributed in its stator slot, its pitch is 1-13,2-12,3-11,4-10,5-9, and its number of turn is distributed as 21,29,36,40,21; Actuating coil 2 is made up of 3 groups of coils, is distributed in the stator slot, and its pitch is 3-17,4-16,5-15, and its number of turn is distributed as 3,4,5; And, centrifugal switch 3 is installed on the armature spindle by series connection one centrifugal switch 3 on the actuating coil 2.This starting structure does not connect power supply, makes actuating coil 2 closed voluntarily by centrifugal switch 3 controls.Centrifugal switch 3 closes when promptly starting, and actuating coil 2 is connected, and by the main field induced current, produces the magnetic field with respect to the main field rotation thus, to promote the cage-type rotor rotation.As electrical motors (75%-80% of rated speed) behind certain rotating speed, this moment, centrifugal switch 3 disconnected voluntarily, and actuating coil 2 opens circuit and no longer works, and at this moment has only main winding 1 and cage-type rotor to carry out the conversion of energy.
