With the development of various industries and the advancement of science and technology, there are quite a few customers' needs, especially scientific research and laboratories, which have high requirements on pump volume, noise and power consumption. It is hoped that the pump can be made smaller and more portable, with lower power consumption, higher efficiency and longer service life. This requires the micro pump manufacturer to strictly evaluate the accuracy and reliability of the pump.

　　The micro-pump using brushless motor has the advantages of long life and ultra-low interference (using electronic commutation). Some high-end products can run continuously for 24 hours in a long time, and can run continuously for a long time even under full load; PWM speed regulation, automatic speed adjustment, to complete the function of the intelligent water pump „. Its superiority is far greater than the micro pump of the brush motor.

　　The ultra-small size weighs only 60 grams, which is more portable, high-quality brushless motor drive, and all moving parts use durable products to improve pump life in all directions. Does not interfere with surrounding electronic components, does not pollute the power supply, will not cause control circuit, LCD screen and other crashes; has a perfect self-protection automatic shutdown function; low noise, low energy consumption, can be installed in any direction;

Advantages of brushless DC water pump:

　　1. The pump shaft is changed into a closed static seal by the dynamic seal, which completely avoids the leakage of the medium; it can be used amphibiously and completely waterproof;

　　2. No need to separate lubrication and cooling water, reducing energy consumption;

　　3. Low power consumption, high efficiency, and damping damping effect, reducing the impact of motor vibration on the pump and the impact of the cavitation vibration of the pump on the motor;

　　4. When overloaded, the rotor will slip on the ceramic shaft, which has a protective effect on the motor and the pump;

　　5. Brushless DC water pump adopts electronic component reversing, no need to use carbon brush reversing, adopts high-performance wear-resistant precision ceramic shaft and graphite sleeve. The bushing is integrated with the magnet through injection molding to avoid wear and tear, so no brush The life of DC magnetic pumps 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.

　　Advantages: 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 precision steel shaft or ceramic shaft with high precision and good shock resistance.

　　Dongguan Dezhi Electronics has been focusing on the R&D and production of medium and high-grade miniature brushless DC water pumps for many years. The “Dezhi” micro brushless DC water pump has a service life of up to 20,000 hours and is widely welcomed by users. It should be noted that today's brushless micro-pumps have gradually replaced the trend of brushed micro-pumps, and future development will be more in line with the higher demand of users.
