Shanxi Submersible Pump Constant Pressure Control

constant pressure control submersible pump
This type of submersible pump is equipped with a water pressure transmitter. During the operation of the pump, the transmitter will convert the pressure of the pump into a changing electrical signal in real time, and then transmit this control signal to the frequency conversion control device (inverter) of the pump. When the pressure of the pump is too high, the frequency of the motor inverter will be reduced accordingly, and the running speed of the motor will be reduced. When the pressure of the pump is too low, the motor frequency converter will increase the frequency accordingly, and the operating speed of the motor will increase accordingly, and the pump pressure can be adjusted in real time to maintain the set pressure value range.
Advantages of Constant Pressure Control of Shanxi Submersible Pump
Because of its simple structure (only pressure transmitter and frequency converter can control the pressure real-time adjustment), low processing and manufacturing costs, good stability. It can meet the requirements of different working conditions, especially in some industries, which have relatively high requirements for constant pressure water supply pressure. The water pressure is too high, the motor power consumption is high, and the pressure impact on the operating pipeline is large, and even the pipeline bursts. The water pressure is too low, the operating efficiency is slow, and the quality of water supply is affected. Therefore, so far, the constant pressure control technology of submersible pump has been widely used, which makes the water supply mode of submersible pump have good performance in water pressure stability, convenience of operation, reliability of use, energy saving and emission reduction.
