Abstract
The utility model provides a submersible motor with a thermal protecting function. The submersible motor comprises a connecting flange installed at the upper part of the casing of the motor, an upper guide bearing support, and an upper end ring mounted at the upper part of a motor casing, wherein the upper guide bearing support is respectively and fixedly connected with the upper end ring and the connecting flange. The submersible motor is characterized in that a PT 100 thermal protector is additionally arranged and fixed on the upper end ring through a lock nut, the bottom part is extended into the inner chamber of the motor, the upper end is connected with a cable, the cable passes through the upper guide bearing support and the connecting flange and is led outside the motor casing, and the cable is sealed through a sealing washer and a sealed pressing plate. In the utility model, the PT 100 thermal protector is fixed inside the motor cavity, the temperature in the inner chamber of the motor is measured and controlled with the variations of the PT 100 thermal protector along the temperature, thereby further ensuring the running temperature of the submersible motor, and prolonging the service life of the submersible motor.
Description
Technical field
The utility model provides a kind of submersible motor with heat protection function, belongs to the submersible motor technical field.
Background technology
The submersible motor operation that generally pulls the plug, and the winding wire of motor internal is water-fast formula winding wire, this winding wire temperature resistant grade is lower, is generally 65 ℃, and insulating material is along with the rising insulation property straight line of temperature reduces.When submersible motor pulled the plug operation, the caloric value of motor sharply rose, and very easily caused the motor windings waterproof wire to cause that because of the motor cavity temperature is too high insulation property reduce, thereby burnt winding.For the internal temperature to submersible motor is monitored; thereby the useful life of control motor; we have installed submersible type heat protection PT100 at motor internal; this protector is very responsive to variation of temperature; to the variation of temperature detection range be ± 0.5 ℃; thermal protector has been arranged, and we can directly control the operating temperature of motor, and motor is operated in the reliable allowed band
The utility model content
The purpose of this utility model provides a kind ofly can monitor the motor cavity internal temperature in real time, prevent that winding from causing the submersible motor with heat protection function that insulation property reduce and then burn because of the motor cavity temperature is too high.Its technical scheme is:
Comprise the adpting flange, upper leading axle bearing and the top ring that are installed in motor casing top; the upper leading axle bearing is fixedlyed connected with adpting flange with top ring respectively; it is characterized in that: set up the protection of PT100 heat; the protection of PT100 heat is fastened on the top ring through locking nut; the bottom probes into motor cavity; last terminated cable, cable pass the upper leading axle bearing and adpting flange is drawn outside the motor casing, realizes cable seal by seal gasket and sealing clamp.
The utility model compared with prior art is fixed on motor cavity inside with thermal protector PT100, along with variation of temperature, realizes the observing and controlling to the motor cavity temperature by PT100, and then guarantees the submersible motor operating temperature, prolongs the useful life of submersible motor.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, motor casing 2, PT100 heat protection 3, locking nut 4, top ring 5, upper leading axle bearing 6, seal gasket 7, sealing clamp 8, adpting flange 9, cable
Embodiment
Upper leading axle bearing 5 is fixedlyed connected with adpting flange 8 with top ring 4 respectively; PT100 heat protection 2 is fastened on the top ring through locking nut 3; the bottom probes into motor cavity; last terminated cable 9; cable 9 passes upper leading axle bearing 5 and adpting flange 8 is drawn outside the motor casing 1, realizes the encapsulation process of motor cavity by seal gasket 6 and sealing clamp 7.
