Micro pump classification and characteristics

Pump industry after decades of development, small size, easy to carry mini-pumps, more and more by the majority of customers are welcome to a simple analysis today, the advantages and disadvantages of various types of mini-pumps. Most of the miniature water pumps on the market today are electric micro-pumps, which are driven by a motor-driven pump (the motor is integrated with the pump chamber and the pump is operated by DC power). So it can also be called "DC micro-pump", so it can be divided according to the type of motor: brush miniature pumps, brushless miniature pumps. 【Features of brushed miniature pump】 Advantages: Brushed motor with big torque is used for power supply, so the flow, suction and pressure can be relatively high. The domestic high-grade brushed motor is relatively mature, Pump manufacturers, the new brand for the Prudential brushes such product quality, performance, reliability are better. And the overall cost is cheaper than the miniature pump with high grade brushless motor. The small pump BSP40160 (Xin Cheng Cheng brand) has relatively large pressure and flow, and is often used for water circulation, cooling, spraying and flushing of new energy electric vehicles Wait. Because of its high suction stroke (4 meters), high pressure, 16 liters / minute open flow, and even full use of the water on the RV, plus a complimentary metal adapter and filter to make it more durable and convenient . Become a popular micro self-priming pump. 【Features of brushless miniature pump】 Advantages: The use of electronic commutation, brushless miniature brushless brush wear limit, so longer life, more suitable for the use of PWM (Pulse Width Modulation), as long as the PWM modulation specifications, the use of single-chip Control circuit control more convenient, and even more complex to achieve more constant current, constant pressure, constant acceleration and more advanced applications. Brushless motor is the core component of brushless miniature pumps, such as the human brain, its quality directly affects the quality, reliability, life expectancy and other key factors of brushless miniature pumps; especially the brushless motor control circuit Is the most important; brushless motor problems are generally out in the control circuit; and domestic brushless motor design, development, production and other levels as a late start, compared with the level of foreign countries have matured, there are still A certain gap; so some light load, the simple situation occasions, low cost brushless motor miniature pumps, but also do not see any problems; but in the event of alternating load, complex conditions, high reliability and stability requirements Occasions, a bit powerless; this time generally experienced professionals, more inclined to use medium and high-end mini-speed pump. For example, in the domestic focus on the production of brushless micro-pump Chengdu Cheng Technology Co., Ltd., the production of miniature pumps, used in all imports of high-grade brushless motor; is divided into non-adjustable speed long-life micro-pump and adjustable speed Of the mini-speed pump two categories: long-life brushless water pump WKY series, WQY series, not only long life, but also dual-use water, water pumping, pumping exhaust. Micro-speed pumps WNY series, WPY series, WUY series, with PWM speed control function, even more complex constant current, constant voltage, constant acceleration and more advanced applications. "New for the honest" brand micro-pumps, adhere to the professional philosophy ...
