35db Low Noise Solar Powered Water Pump 12v Dc Long Service Life

Longlife Low Noise Within 35db 12v DC Solar Powered Water Pump​​

Paramerter:

Solar water pumps (also known as photovoltaic water pumps) are the most attractive water supply methods in the sun-rich areas of the world, especially in remote areas where electricity and electricity are scarce. Using solar energy that is available everywhere and inexhaustible, the system is fully automatic. It is a green energy system that combines economics, reliability and environmental benefits. It is a work-out, sunset break, no need for personnel to take care of, and maintenance workload can be minimized.

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.

Advantage

(1) Reliable: Photovoltaic power supplies rarely use moving parts and work reliably.

(2) Safe, no noise, no other public hazards. Does not produce any solid, liquid and gaseous harmful substances, absolutely environmentally friendly.

(3) Simple installation and maintenance, low operating cost, suitable for unattended. In particular, it is highly regarded for its high reliability.

(4) Good compatibility, photovoltaic power generation can be used together with other energy sources, and the photovoltaic system can be easily added to capacity as needed.

(5) The degree of standardization is high, and the components can be connected in series and parallel to meet the needs of different power consumption, and the versatility is strong.

(6) Solar energy is available everywhere and has a wide range of applications.
However, solar energy systems also have their shortcomings, such as: energy dispersion, intermittent, and regional. The upfront costs are higher.

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.
