Solar Submersible Pump

    Solar submersible pumps are divided into the following three categories:
    1. Brush solar submersible pump
    When the water pump is working, the coil and commutator rotate, but the magnets and carbon brushes do not rotate. The alternating change in the direction of the coil current is completed by the commutator and brushes as the motor rotates. As long as the motor rotates, the carbon brushes will wear. When the computer water pump runs to a certain point, the wear gap of the carbon brushes becomes larger, and the sound also increases. After running continuously for hundreds of hours, the carbon brushes can no longer play the role of reversing direction.
   Advantages: low price.
   2. Brushless motor solar submersible pump
   The motor-type brushless solar submersible pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected to the impeller, and there is a gap between the stator and the rotor of the water pump. Over time, water will penetrate into the motor and the motor will easily burn out.
   Advantages: Brushless DC motors are standardized, low cost, and highly efficient.
   3. Brushless DC magnetic drive solar submersible pump
   The brushless DC water pump uses electronic components for commutation, without the need for carbon brushes. It uses a wear-resistant ceramic shaft and ceramic bushing. The bushing is integrated with the magnet through injection molding to avoid wear. Therefore, the brushless DC magnetic water pump lifespan increased. The stator part and rotor part of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are potted with epoxy resin, which has good waterproof performance. The rotor part uses permanent magnets. The water pump body is made of environmentally friendly materials. It has low noise, small size and high performance. Stablize. Various required parameters can be adjusted through the winding of the stator and can operate at a wide voltage range.
   Advantages: long life, low noise below 35dB, high temperature resistance, and can be used for hot water circulation. The stator and circuit board of the motor are potted with epoxy resin and completely isolated from the rotor. They can be installed underwater and are waterproof. The axis of the water pump uses a ceramic shaft, which has good shock resistance.
