The brushless DC submersible pump is a kind of water pump powered by direct current to replace the traditional mechanical commutator to realize the impeller steering.  Its advantages include small size, high efficiency, low noise, long life and so on.  The circuit board plays a very important role in the brushless DC submersible pump. It is the control center of the whole pump, responsible for receiving input signals, processing and computing, and output control signal to control the operation of the pump.

     Circuit boards usually include microcontrollers, sensors, amplifiers, drivers and other electronic components. The following are some of the main functions of the circuit board in the brushless DC submersible pump: ①: Control the operation of the water pump: The circuit board receives input signals, such as water level sensor signal, flow sensor signal, etc., for processing and transportation Calculate, and output the control signal to control the operation of the water pump. It can automatically control the speed and steering of the pump according to the need to achieve the best operation effect. ②: Protective water pump: The circuit board also includes various protection circuits, such as overvoltage protection, overcurrent protection, overheating protection, etc. These protection circuits can ensure that the pump is not damaged in abnormal circumstances and prolong the service life of the pump.

③: Improve the reliability of the water pump: The sensors and amplifiers on the circuit board can detect the operating condition of the pump, such as water level, flow rate, temperature, etc., and convert these signals into digital signals for processing.       The circuit board can be diagnosed according to these signals, and timely detection and troubleshooting, improve the reliability of the water pump.④: Reduce the noise of the water pump:       The brushless DC submersible pump replaces the traditional mechanical commutator, reducing friction and vibration, and thus reducing the noise of the pump.      The driver in the circuit board can control the operation of the electronic commutator to achieve a better noise reduction effect.      To sum up, the circuit board plays a vital role in the brushless DC submersible pump, it can not only automatically control the operation of the pump, but also can protect the pump, improve the reliability of the pump, reduce the noise of the pump, etc.
