the control system has high reliability and the system pressure keeps constant when the load changes. The system is controlled by 4 inverters, of which one is in system a, two are in system B, and one is shared by both systems. On the one hand, the system can keep the water supply pressure constant without fluctuation when starting and stopping the standby pump, on the other hand, the system cost is reduced. Two plcs are used for control. A main control PLC as a system, at the same time as a B system of backup control PLC. The other one is the Master Control Plc of B system and the backup control Plc. . In this way, when one PLC is out of order, the other PLC is responsible for all control tasks of the whole system, and there is no disturbance switch, so that the system will not stop working due to the failure of one PLC, thus affecting the safety of production. After PID calculation, the result is sent to the converter in the form of 4-20mA current signal, and the output frequency of the converter is adjusted in time so as to adjust the speed of the motor and make the water supply pressure constant. Frequency converter will also output current in the form of 0-10V voltage signal to the PLC, so that timely according to the load of the PLC pump standby pump start and stop.

山上住著三老子，山下住著三小子，山腰住著三哥三嫂子。
山下三小子，找山腰三哥三嫂子，借三斗三升酸棗子，
山腰三哥三嫂子，借給山下三小子三斗三升酸棗子。
山下三小子，又找山上三老子，借三斗三升酸棗子，
山上三老子，還沒有三斗三升酸棗子，
只好到山腰找三哥三嫂子，給山下三小子借了三斗三升酸棗子。
過(guò)年山下三小子打下酸棗子，還了山腰三哥三嫂子，兩個(gè)三斗三升酸棗子。
