The 3 lines of the remote pressure gauge are connected to an external potentiometer of the frequency converter. What parameters can be adopted to adjust the pressure? Thank you
Frequency converter to "advanced parameters", in the PID function to set the corresponding parameters, such as: set the channel, feedback channel, control structure, pressure meter range, upper and lower limit values, etc.. With keyboard control or external terminal control operation and stop, panel potentiometer adjust the pressure
It must be a frequency converter with a PID regulator, and the potentiometer is connected to the feedback loop. The system pressure can be automatically adjusted by setting the pressure value and the PID parameter on the inverter.
Constant pressure water supply principle of remote pressure gauge:1. use frequency conversion motor to realize constant pressure water supply. Constant pressure water supply system based on pipeline pressure (i.e. remote pressure gauge readings) to set parameters, through computer-controlled inverter output frequency to adjust the rotational speed of water pump, to achieve closed-loop pipeline pressure regulation (PID), the automatic water supply system of constant to the set pressure value: the water consumption increases, the frequency increases, the pump speed is accelerated, water supply increases; reduce water consumption, reduce the frequency of pump speed slow down, water supply is reduced, so as to ensure the water supply efficiency requirements of water pressure and water at the same time, to improve the water quality and water supply efficiency, "how much water, how much water supply"; the device does not need to build the high water tank, water tower, no two pollution, is a modern building water supply equipment ideal.2. use the regulating valve to realize constant pressure water supply. The constant pressure water supply system based on pipeline pressure (i.e. remote pressure gauge readings) to set parameters, the computer controls the pump outlet valve open, closed loop water pressure regulation (PID), the automatic water supply system of constant to the set pressure value: the water consumption increases, the valve opening increases, water supply increases; reduce water consumption, reduces the valve opening, water supply is reduced, so as to ensure the water supply efficiency requirements of water pressure and water at the same time, in order to improve the water quality and water supply efficiency, "how much water, how much water supply".
