Micro DC water pump is used for conveying liquid or pressurizing liquid machinery, often used in drinking machine, coffee machine and other equipment. Traditional micro water pump usually adopts brush motor, large volume, pump work, rotor continuous rotation to form carbon brush wear, easy to produce sparks and noise, medium into the gap between stator and rotor easy to burn out the motor, short service life.
The basic structure of the micro DC water pump is clarified, the front end of the micro DC water pump cover is provided with a water inlet hole, one side of the end cover is provided with a water outlet hole, and an axially extended rotor shaft is arranged between the end cover water inlet hole and the back shell jack.
Micro DC water pump with high efficiency and low energy consumption induction components, with intelligent electronic drive circuit, the use of scientific fluid design, so that the overall performance of the improvement of the traditional water pump 20%, while the common design makes the pump more quiet, more stable. Very suitable for water circulation, heat dissipation system and fountain landscaping.
Micro DC pumps can be loud in many ways (not necessarily the pump sound)
1, water shortage, motor idling, the sound will increase significantly;
2, the pump working time is too long in the inside of scale will produce noise;
3, the inlet infarction will produce negative pressure
In order to achieve the ultimate quiet micro DC pump, first in the structure of the design of the ring to control the tolerance to the best size. The mold must use fine mold, the main processing process data selection must use raw materials, recycled material is not able to do the high precision of the main structure. Secondly, the stator parameters of USB micro DC water pump should be designed to match the height of the main body, and the speed can not be too fast, because the noise is proportional to the speed, but the speed can not be too slow. It will make the pump less than optimal performance. Reduce the use of efficiency, low speed will make the rotor swing unstable.
Host structure and parameter processing, and assembly is also important, the circuit board must do waterproof treatment, connection power line must not have virtual welding, virtual welding not only affects the life of the pump, but also produces high-frequency current sound. Any pump will have large or small vibration, so will add rubber pad, micro DC pump is no exception, micro DC pump rubber pad must use silica gel information. Ordinary data will harden and become more noisy. Do these, a quiet performance of the ultimate micro DC pump produced.
