Brushless DC speed regulating water pump, PWM speed regulating principle of three-phase brushless DC speed regulating water pump

Brushless DC speed regulating water pump, PWM speed regulating principle of three-phase brushless DC speed regulating water pump

PWM speed regulating water pump means that the speed of the water pump can be changed through PWM, thereby changing the head, flow and other parameters of the water pump. This speed-regulating water pump is a high-end product of the micro pump type.PWM water pumps have two speed-adjustable models:1. Adjust the input voltage directly through PWM.2. The input voltage of the water pump remains unchanged. The water pump uses a sensorless program driver (three-phase sensorless driver) to directly input the PWM speed regulation signal to the control MCU.The water pump includes FG feedback control signal, forward and reverse control signal...

Application of brushless DC water pump

Application of brushless DC water pump

    1. Car water pump: car electronic water pump, car electric water pump, car parking heater water pump, preheater water pump, car warm air circulation, car engine refrigeration, etc., car battery refrigeration, motorcycle electric water pump, etc. Many special vehicles such as new energy vehicles and RVs often use micro water pumps as water circulation, cooling or on-board water supply systems. The working environment requirements are: -40 degrees to 150 degrees. China has already successfully developed alternative automotive electronic water pumps, breaking this pattern.2. Solar water pump: Solar panels are used to directly drive the water pump. The solar...

Ozone Mystery: the story of ozone in China in the new era after 2000

Ozone Mystery: the story of ozone in China in the new era after 2000

The Development of Ozone Technology in China after 2000  Research on Ozone Generation Technology in China after 2000 Wang Fang and others in the 309th Hospital of the People’s Liberation Army studied the effect of peptone on the germicidal efficacy of the ozone water, turning out that organics in water could destroy ozone and reduce its sterilization effect.   According to the years of research on ceramic chips, Ni Guonian and Sui Ying of Beijing Institute of Technology drafted "Performance Testing and Acceptance Standards for Ceramic Chips in Surface Discharge" in 2000, and improved the nickel plating process of tungsten electrodes for...

Ozone Mystery: the story of ozone in China in the 80s and 90s

The Development of Ozone Technology in China in the 1980s Research on Ozone Generation Technology in China in the 1980s Around 1980, with the technical support of the East China Institute of Chemical Technology, Li Aicheng in Taixing Environmental Protection Plant embarked on the production of ozone generators and high-speed stirring ozone absorbers. After accepting relevant technology transfer from Tsinghua University, he devoted himself to the production of two types of ozone generators at the same time. In the early 1980s, a 1 kg/h Industrial frequency high voltage ozonizer was produced. In the following two decades, it was the two enterprises...
