Description
Technical field
A kind of well submersible motor of the utility model is vented water charging system, belongs to submersible electric motor technical field.
Background technology
Submersible motor voltage-regulating system major part in the market adopts rubber pressure regulator membrane to add pressure spring voltage-regulating system, its shortcoming is: 1. voltage-regulating system has an air-vent that must arrange and extraneous UNICOM, the easy like this foreign material such as silt that cause block pressure regulation space, even foreign material puncture pressure regulator membrane, cause submersible motor to leak or silt enters and causes motor damage.2. there is certain air unavoidably in motor cavity, when particularly motor cavity temperature is higher, partial air is separated out from motor cooling water, swims in the upper end of motor, and high-temperature gas is easy to cause motor winding upper end premature aging, finally cause electrical machine insulation to reduce, electrical machinery life shortens.
Utility model content
The utility model overcomes the deficiency that prior art exists, provide a kind ofly automatically to be exhausted motor cavity, the well submersible motor of moisturizing is vented water charging system, this system configuration simply, is skillfully constructed and effectively can extends the useful life of motor.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of well submersible motor is vented water charging system, comprise submersible motor body, water intaking valve and vent valve, described water intaking valve and vent valve are all arranged on the shell of submersible motor body, described water intaking valve and vent valve are all communicated with the inside of submersible motor body, described water intaking valve is used for immersible pump body interior supplementing water, and described vent valve is for discharging the gas of immersible pump body interior;
Described immersible pump body is provided with filter, and described filter bits is in the outer end of water intaking valve, and described filter is for removing the impurity entered in immersible pump body interior water.
Described water intaking valve and vent valve are unidirectional valve.
Described water intaking valve and vent valve are all arranged on the top of submersible motor body.
The beneficial effect that the utility model compared with prior art has is: the utility model utilizes unidirectional valve principle, pushes unidirectional valve open discharge outside submersible motor at submersible motor chamber pressure higher than the gas of motor cavity during exhaust check valve setting pressure or liquid; When motor cavity pressure is less than moisturizing unidirectional valve setting pressure, extraneous water enters motor for submerged pump inner chamber by filter, motor cavity pressure stability is kept by this system, filter is connected in water compensating valve outlet its import inwardly, can effectively stop the foreign material such as silt and enter submersible motor inside, the utility model is simple and practical, effectively can extend the useful life of motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is utility model works schematic diagram.
In figure, 1 be submersible motor body, 2 be water intaking valve, 3 be vent valve, 4 for filter.
Embodiment
As shown in Figure 1 and Figure 2, a kind of well submersible motor of the utility model is vented water charging system, comprise submersible motor body 1, water intaking valve 2 and vent valve 3, described water intaking valve 2 and vent valve 3 are all arranged on the shell of submersible motor body 1, described water intaking valve 2 is all communicated with the inside of submersible motor body 1 with vent valve 3, described water intaking valve 2 is for giving the inner supplementing water of submersible motor body 1, and described vent valve 3 is for discharging the gas of submersible motor body 1 inner chamber;
Described water intaking valve 2 is provided with filter 4, and described filter 4 is positioned at the outer end of water intaking valve 2, and described filter 4 is for removing the impurity entered in submersible motor body 1 internal water.
Described water intaking valve 2 and vent valve 3 are unidirectional valve.
Described water intaking valve 2 and vent valve 3 are all arranged on the top of submersible motor body 1.
The utility model utilizes unidirectional valve principle, in the top of motor for submerged pump, double check valve structure is set, wherein vent valve outlet outwardly, water compensating valve exports import inwardly and connects filter, pushes unidirectional valve open discharge outside immersible pump at submersible motor chamber pressure higher than the gas of motor cavity during exhaust check valve setting pressure or liquid; When motor cavity pressure is less than moisturizing unidirectional valve setting pressure, extraneous water enters motor for submerged pump inner chamber by filter, motor cavity pressure stability is kept by this system, export import inwardly at water compensating valve and connect filter, can effectively stop the foreign material such as silt and enter submersible motor inner chamber, the utility model is simple and practical, effectively can extend the useful life of motor.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
