Background
At present, a conventional shaft type installation system is provided with a dry type submersible motor, the protection grade of the submersible motor with the structure needs to reach IP68, the requirement on the sealing condition of the motor is very high, and if the sealing is poor or a sealing element is aged or damaged, the electric pump needs to be stopped and returned to a factory for maintenance to be continuously used. The full-through-flow submersible electric pump is a wet submersible electric pump, cannot be used due to poor sealing, is also a special waterproof line for windings, and cannot seep water or leak electricity after being soaked in water for a long time.
The wet submersible electric pumps are generally QJ-type well submersible electric pumps, QS-type water-filled electric pumps and QKSG-type mining submersible electric pumps. These types of wet submersible electric pumps are water-filled submersible electric pumps, which are generally filled with water from the motor cavity after the entire pump has been assembled and tested, and then the water filling port and the air vent are sealed. Such products are relatively complex in construction and difficult to use in wellbore installation systems. Meanwhile, the water-filled submersible motor does not directly cool the motor winding by flowing water, but the heat generated by the winding is dissipated in the internal water and is cooled by the heat conduction of shells such as a motor shell and the like. The motor of the full through-flow submersible electric pump is communicated with external water, winding coils of the full through-flow submersible electric pump are soaked in the water, heat generated by the coils is carried away along with water flow, and the temperature of the internal water is basically the same as that of transportation water, so that the temperature of the windings does not need to be monitored.
When transforming in some old pump stations, need change into the submerged motor pump that can satisfy service condition especially, nevertheless because of receiving pump station self condition: the weight or height of the conventional submersible axial mixed-flow electric pump cannot meet the requirements of field hoisting or installation due to the limitation of hoisting or installation height, so that compared with a full-through-flow pump with the same specification parameters, the structure and weight of the pump are more than half smaller than those of the conventional submersible axial mixed-flow electric pump.
