Abstract
The utility model relates to the field of machinery, and especially relates to a submersible motor with a protector and a moment type overload protector. The submersible motor with the protector comprises a submersible pump and a submersible motor. The submersible motor with the protector is characterized in that the overload protector is arranged between the submersible pump and the submersible motor, the overload protector comprises an upper shaft coupling and a lower shaft coupling, a telescoping device is arranged between the upper shaft coupling and the lower shaft coupling, the telescoping device comprises a belleville spring assembly and an adjusting nut arranged under the belleville spring assembly, the lower shaft coupling is arranged under the adjusting nut, and the side faces of the telescoping device are provided with a waterproof housing. By employing a waterproof structure design in the submersible motor with the protector, when the submersible motor is used in deep well water and a load driven by the motor exceeds a rated load of the motor, the submersible motor with the protector starts to slip and the motor starts to idle, and a good overload protection effect to the submersible motor is formed.

Utility model content
The object of utility model: for a kind of defencive function that has is provided, the submersible motor with protector and torque type overload protective device that can automatic stall when resistance is large.
In order to reach as above object, the utility model is taked following technical scheme:
Scheme 1:
Submersible motor with protector; comprise immersible pump and submersible motor, it is characterized in that, between described immersible pump and submersible motor, have overload protective device; described overload protective device comprises upper coupling and lower coupler, between described upper coupling and lower coupler, has retractor device.
The further technical scheme of the utility model is, the adjusting nut that described retractor device comprises butterfly spring group and is positioned at groups of springs below, and adjusting nut below is lower coupler.
The further technical scheme of the utility model is, described retractor device avris also has waterproof case.
The further technical scheme of the utility model is, described submersible motor connects retractor device by upper coupling, strong transducer between described upper coupling and submersible motor.
The further technical scheme of the utility model is, on described adjusting nut, comprises hold-down bolt, described hold-down bolt energy and waterproof case locking.
Scheme 2:
Submersible motor torque type overload protective device, is characterized in that, comprises upper coupling and lower coupler, between described upper coupling and lower coupler, has retractor device.
The further technical scheme of the utility model is, the adjusting nut that described retractor device comprises butterfly spring group and is positioned at groups of springs below, and adjusting nut below is lower coupler.
The further technical scheme of the utility model is, described retractor device avris also has waterproof case.
Adopt as above the utility model of technical scheme; there is following beneficial effect: when this device has guaranteed that by waterproof construction design submersible motor is used in phreatic water; when motor institute bringing onto load surpasses motor rated load; this device starts to skid; motor starts idle running; submersible motor has been formed to good overload protective function, and the use of this protector, effectively reduces the well maintenance and repair cycle that immersible pump and submersible motor are used producer.Save the cost of buying new submersible motor, improved the service efficiency of original immersible pump.Saved use producer total cost.This device structure is simple, reasonable in design, easy to use.
Accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structural representation of utility model;
Wherein: 1. immersible pump; 2. overload protective device; 3. submersible motor; 4. upper coupling; 5. waterproof case; 6. butterfly spring group; 7. adjusting nut; 8. lower coupler.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
Scheme 1:
3. with the submersible motor of protector; comprise immersible pump 1 and submersible motor 3; it is characterized in that; between described immersible pump 1 and submersible motor 3, there is overload protective device 2; described overload protective device 2 comprises upper coupling 4 and lower coupler 8, between described upper coupling 4 and lower coupler 8, has retractor device.The adjusting nut 7 that described retractor device comprises butterfly spring group and is positioned at groups of springs below, adjusting nut below is lower coupler 8.Described retractor device avris also has waterproof case 5.Described submersible motor 3 connects retractor device by upper coupling 4, strong transducer between described upper coupling 4 and submersible motor 3.Described hold-down bolt energy and waterproof case 5 lockings.
Scheme 2:
Submersible motor torque type overload protective device, is characterized in that, comprises upper coupling 4 and lower coupler 8, between described upper coupling 4 and lower coupler 8, has retractor device.The adjusting nut 7 that described retractor device comprises butterfly spring group and is positioned at groups of springs below, adjusting nut below is lower coupler 8.Described retractor device avris also has waterproof case 5.
Its operation principle is as follows:
First: according to the actual power of the submersible motor 3 of measuring; the adjusting nut of overload protective device 2 is adjusted to the peaked position of overload power that submersible motor 3 is set; hold-down bolt above locking adjusting nut; by the waterproof case of overload protective device 25 locking firmly, by upper coupling 4 and lower coupler 8 by immersible pump 1 and submersible motor 3 firm and reliable connection.
