Box no negative pressure water equipment specifically for intelligent pumping station in harsh environments, no, need constant water supply, stable operation and R & D - box no negative pressure water supply equipment constant pressure water supply system works using a potentiometer After setting the pressure (inside the panel can also be used to set pressure), using a pressure sensor (feedback is 4 ~ 20mA) to detect the pipe network pressure, the pressure sensor signal into the inverter PID loop, PID loop handle, send a water increase or decrease the signal to control the motor speed. If within a certain delay time, the pressure is still insufficient or too large, then the laborers through the inverter frequency / inverter switching start another pump, so that the actual pressure in the pipe is consistent with the set pressure. With the reduction of water consumption, the inverter automatically reduces the output frequency or the removal of the pump, to the conservation of energy. Box no negative pressure water equipment operation manual: The Mitsui power supply controller, the default for automatic operation mode, press "A / M" key to enter the manual operation mode. Manual operation mode, you can modify the system parameters. In this mode, only the control of each pump frequency operation. Recommend any parameter changes are carried out in the manual mode. When the pump is stopped, press the corresponding ON / OFF button to start the pump frequency, the corresponding indicator lights up red. . When the pump is running, press the corresponding ON / OFF button to stop the pump frequency operation, the corresponding LED is off. There are two modes of operation run automatically without negative pressure water equipment box mode one: when regular water supply mode (cycle start mode) system to work, to enter the automatic operation, the pump number n run first by setting the drive starts, when the pressure Below increase pump pressure, delay T1 (by pump delay) n number of stops the pump frequency, delay T2 (variable delay changing jobs) will switch to n number of pump frequency operation, then the delay T3 (work shift Delay) drive start on the 1st n + pump, water supply system is "a worker a change" operation. When the box is no negative pressure water supply equipment when the pressure is still below the increase in pump pressure, delay T1 (by pump delay) stop n + 1 pump frequency, delay T2 (variable delay changing jobs) will be n + 1 Pump switched to frequency operation, then the delay T3 (work shift delay) drive start n + 2 pump, the water supply system is in "two workers a change" operation.
