Principle

The motor type brushless DC water pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected to the impeller. There is a gap between the stator and the rotor of the pump. After a long time of use, water will penetrate into the motor and increase the possibility of motor burnout.
Brushless DC magnetic isolation solar water pump
The brushless DC water pump adopts electronic component reversing, no need to use carbon brush reversing, and adopts high-performance wear-resistant ceramic shaft and ceramic bushing. The bushing is integrated with the magnet through injection molding to avoid wear, so the brushless DC magnetic force The life of the pump has been greatly enhanced. The stator part and the rotor part of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are sealed with epoxy resin, 100% waterproof, the rotor part is made of permanent magnet, the pump body is made of environmentally friendly materials, low noise, small size, performance. stable. Various required parameters can be adjusted by winding the stator and can be operated at a wide voltage.

Brushless DC solar water pump (motor type)

Brushless DC solar water pump (magnetic drive isolated)

Characteristics of various solar water pumps

1.  Brushed DC solar water pump:

When the pump is working, the coil and the commutator rotate, the magnetic steel and the carbon brush do not rotate, and the alternating current direction of the coil is completed by the commutator and the brush that the motor rotates, as long as the motor rotates the carbon brush, the wear occurs. When the computer water pump runs to a certain extent, the carbon brush wear gap becomes larger and the sound will increase accordingly. After several hundred hours of continuous operation, the carbon brush cannot play the role of reversing.

Advantages:

1. The motor type brushless DC water pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected with the impeller. There is a gap between the stator and the rotor of the water pump. When the water is used for a long time, the water will penetrate into the motor and increase the possibility of motor burnout.

2. Brushless DC motors have been standardized, and there are a large number of specialized manufacturers, which are relatively low in cost and high in efficiency.

3. Brushless DC magnetically isolated solar water pump: The brushless DC water pump uses electronic components to commutate without using carbon brush reversing. It uses high-performance wear-resistant ceramic shaft and ceramic bushing. The bushing is integrated with the magnet through injection molding. The wear is also avoided, so the life of the brushless DC magnetic pump is greatly enhanced. The stator part and the rotor part of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are sealed with epoxy resin, 100% waterproof, the rotor part is made of permanent magnet, the pump body is made of environmentally friendly materials, low noise, small size, performance. stable. Various required parameters can be adjusted by winding the stator and can be operated at a wide voltage.

4. long life, low noise up to 35dB, can be used for hot water circulation. The stator and circuit board parts of the motor are encapsulated with epoxy resin and completely isolated from the rotor. They can be installed underwater and completely waterproof. The shaft of the pump is made of high-performance ceramic shaft with high precision and good shock resistance.

Outlook

At present, the efficiency of silicon solar panels is difficult to increase in a short period of time. Although the second-generation thin-film solar cells and the third-generation organic solar cells have obvious advantages in cost, they are currently mass-produced with silicon solar panels. Compared to not competitive. In the future, silicon panels will still occupy a large market share. Therefore, in the future, the research and development direction of solar pump systems should focus on the following three aspects:

(1) Research and development of high-efficiency pumps and motors to improve the range of high-efficiency zones of motors and pumps under a wide range of speeds and flow rates and to reduce the system's pumping threshold power. Develop low-cost, high-reliability intelligent controllers to improve performance matching between components and respond to changing weather conditions, thereby improving system dynamic quality and overall efficiency. At the same time, the development and promotion of comprehensive technologies for complementary energy utilization of small and medium-sized wind-light-heat;

(2) General methods for predicting long-term performance of solar pump systems under multi-factor changes such as climate, light, water level and water demand, and system design methods based on dynamic changes, establishing databases in different regions to gradually replace the method of estimating static averages ;

(3) With the reduction of the price of the panel and the development of small and medium-sized solar systems, in the future, on the basis of optimizing the power of the panel, the evaluation of the operational reliability of the system should be increased to improve the long-term reliability of the system and the stability of the water supply.
