Water and fertilizer automation equipment - constant pressure pumping station

Water and fertilizer automation equipment - constant pressure pumping station

The system is controlled by the intelligent central processor, the pressure controller on the outlet pipe network samples the water pressure and converts it into the corresponding electrical signal to the PLC, the PLC receives the actual pressure signal of the pipe network and compares it with the pressure value set by the user, and uses the deviation value to control the output frequency of the inverter to change the output power of the motor. When a pump is running at full speed and still cannot reach the user's set pressure, the variable frequency pump is switched to power frequency operation, and the frequency converter soft starts another pump and runs at low frequency. If the actual pressure is greater than the set pressure, the power frequency pump is automatically stopped, so as to achieve variable constant pressure water supply. If the water consumption is very little, then stop all the active, by the auxiliary pump and pressure tank work constant pressure.
