Problems solved by technology
[0003] At present, the existing submersible pumps still have deficiencies. When the existing submersible pumps work, they conduct heat dissipation and cooling through the surrounding water body. Once the motor is exposed, it will inevitably cause poor heat dissipation of the pump motor, and its temperature will rise sharply, thus causing the motor to burn out. Seriously affect the service life, and the current of the submersible pump is very large when it starts, and the motor winding will be burned out when it is started frequently. Special personnel are on duty, resulting in increased pumping and drainage costs, so a protection method for shallow water pump motors is urgently needed to solve the above problems

The invention discloses a protection method and device for submersible pump self-circulation water cooling motor. The device comprises a pump body, an output end and a water inlet, wherein a submersible pump cable is arranged at the top of the pump body, and a filter screen is arranged on the inner surface wall of the vertical end of the water inlet. According to the protection device and device for the submersible pump self-circulation water cooling motor, a steel pipe sheath is additionally arranged on the submersible pump body, a water flow channel is formed between the pump body and the steel pipe sheath, the water outlet of the device is formed in the top of the shell, when the pump body works, water body is guided in from the water inlet, the water body guided in by the pump body isthrown into a cavity from the output end, the water body is discharged from the water outlet through pressure along with continuous increase of the water body in the cavity, and the cavity between thepump body and the steel pipe sheath is filled with flowing water all the time, so that heat emitted by a motor inside the pump body is taken away, the whole cooling effect of the water pump motor isachieved, meanwhile, the newly added steel pipe sheath can further play a role in protecting the pump body, and the using effect of the submersible pump is improved.
Description
technical field [0001] The invention relates to the technical field of submersible pumps, in particular to a protection method and device for a self-circulating water cooling motor of a submersible pump. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water and extracts groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. [0003] At present, the existing submersible pumps still have deficiencies. When the existing submersible pumps work, they conduct heat dissipation and cooling through the surrounding water body. Once the motor is exposed, it will inevitably cause poor heat dissipation of the pump motor, and its temperature will rise sharply, thus causing the motor to burn out. Seriously affect the service life, and the current of the submersible pump is very ...
