A permanent magnet solar DC deep well pump

Abstract

The invention provides a permanent magnet solar direct-current deep-well pump, and belongs to the technical field of water pumps. The problem that a controller of an existing solar deep-well pump is poor in heat dissipation performance is solved. The permanent magnet solar direct-current deep-well pump comprises a motor cylinder and a controller, wherein a lower bearing seat is fixedly connected in the motor cylinder; an inner cavity of the motor cylinder is divided into a motor cavity and a heat dissipation cavity by the lower bearing seat; an oil injection hole is formed in the motor cylinder; the heat dissipation cavity communicates with the motor cavity; a sealed container is arranged in the heat dissipation cavity; the controller is sealed in the sealed container; the upper end of thesealed container abuts against and is fixedly connected with a lower bearing seat; the lower bearing seat and the sealed container are both made of heat conduction metal materials; and a gap is formed between the outer surface of the sealed container and the inner surface of the motor cylinder. The permanent magnet solar direct-current deep-well pump is better in heat dissipation performance andhigher in stability.

Description

technical field [0001] The invention belongs to the technical field of water pumps and relates to a permanent magnet solar DC deep well pump. Background technique [0002] Solar water pump converts light energy into electrical energy through solar equipment, and provides working power for the load pump motor. It is the most attractive water supply method in sunny areas, especially in remote areas without electricity. Because the light intensity will change in real time , so the solar water pump needs to cooperate with the controller to adjust the output frequency in real time. At present, the controller is usually placed outside the water with the solar equipment and instruments. The energy-saving deep well pump that can automatically cut off the power supply and achieve energy saving effect solves the technical problems of high energy consumption and waste of electric energy in the existing deep well pump, including the pump body and the frequency conversion motor.

[0002] Solar water pump converts light energy into electrical energy through solar equipment, and provides working power for the load pump motor. It is the most attractive water supply method in sunny areas, especially in remote areas without electricity. Because the light intensity will change in real time , so the solar water pump needs to cooperate with the controller to adjust the output frequency in real time. At present, the controller is usually placed outside the water with the solar equipment and instruments. The energy-saving deep well pump that can automatically cut off the power supply and achieve energy saving effect solves the technical problems of high energy consumption and waste of electric energy in the existing deep well pump, including the pump body and the frequency conversion motor. The frequency conversion motor is connected with an energy-saving circuit. Including starting unit, adjusting unit, control unit and execution unit, the starting unit is connected between the frequency conversion motor and the power interface, and the energy-saving circuit such as the control unit is set at the plug, but the controller will generate a lot of heat when it is working, and the control unit lacks Effective heat dissipation, resulting in poor working stability
