When a user less than a water pump out water, the control system according to changes in water has a water pump to adjust the operating frequency, when the water increases the pressure drop within the piping system, when the pressure sensor to detect the signal transmitted to the computer control unit, run by computer to determine, issue commands to the inverter to control the pump motor, the speed is accelerated to ensure that the system pressure constant, whereas when the water was reduced, the pump speed slows down to maintain constant pressure. When the water is greater than a water pump, the first pump switching frequency operation, the second pump start frequency adjustment operation, when the water is greater than two pumps out water, it will automatically stop one or two sets of pump operation . Throughout the operation, and always maintain the same constant pressure system, the pump is always working in the high zone, both to ensure constant water supply users, but also saves energy. The traditional way of water supply is inseparable from the reservoir, the water in the pool is generally supplied by the water pipe network, so that the pressure of the water entering the pool becomes zero, causing a lot of energy wasted. Whale JYW type non-negative steady flow pressurized water supply equipment, our company is professional and technical personnel in the frequency of water supply equipment developed on a direct connection with the water pipe network, and the water pipe network does not produce any negative two secondary pressurized water supply equipment, on the basis of the original pressure, pressure difference how much make up.

When one inverter to control two motors, in principle, the inverter is equipped with a motor capacity should be equal to the sum of two electric motors of capacity. However, if at the time of peak load of water supply quantity than two pumps at full speed a lot of difference, may consider appropriate to reduce the capacity of the drive, but it should be noted that there is adequate capacity. While the pump is running at low speed, motor current is small. However, when the user changes frequently water, the motor will be in frequent, deceleration state, and acceleration and deceleration of the current can be slightly more than the rated current of the motor, causing the motor to overheat. Therefore, the motor thermal protection is required. This temperature rise due to frequent acceleration and deceleration and accumulated, electronic thermal protection inside the inverter is difficult to play a protective role, it should be used for the motor thermal relay thermal protection. In the main function of preset aspect, the highest frequency should be rated for the maximum operating frequency of the motor frequency inverter. Acceleration and deceleration time in the case of PID regulator case, deceleration time should be set too short, so as not affect the dynamic response of the PID regulator decision. Such as the inverter itself has PID adjustment function, simply set the preset PID function is active, the set-up and spin-down time will automatically lapse. The main function of a whale water supply equipment, automatic completion of more than one water pump soft-start, frequency conversion process to the entire operation frequency operation and stop. 2, according to changes in water into more than one pump start and stop. 3, LED pressure setpoint and the actual pressure value display. 4, LED frequency indicator, frequency exception indicates, the electrical fault condition display. 5, protection features: undervoltage protection, overvoltage, overload, short circuit protection, stall prevention, burning to prevent.
