Shaanxi Shaanxi overlying water supply equipment prices overlying water supply equipment manufacturers preferred price first quality, selecting the best, come Xing rise of water, here to give you the best service, the best quality, the water supply service hotline 400-0030-929. Those people with the confidence to pursue excellence, spirituality will get washed in Endeavour insisted, those who dare to survive in the face of adversity, stare in the mirror image, the will be able to see their true appearance. Overlying water supply equipment prices work (1) manual mode is reliable and easiest way. (2) Automatic mode is the normal operating mode, have the following characteristics: ① Each automated system can be controlled 2-5 pumps work mutually preparation station, operation of the pump, follow the first open the first stop, the first stop first, the principle of balanced working hours, work intensity of the pump rather, a water pump to avoid long-term use causes excessive wear or corrosion, thereby effectively extending the life of each pump. ② user-friendly, the system uses can touch interface. ③ operation of pump constant pressure value output accuracy effectively guaranteed within 0.01MPa, by computer simulation pipe network characteristic curve, adjust the pump to work in the high zone, the whole better. ④ system has run, stop and fault display functions. Overlying water supply equipment works automatically adjust the price to run a number of pump units and water pump speed changes according to the user, the pump outlet pressure constant. 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. Overlying water supply equipment prices pump switching, inverter fault is not 0 user first controller to determine whether all the control lines of the inverter connected. If the drive does not slide stop input signal. When the pump switching action, the controller will drive a taxi stop signal, ie EMG signals. If the EMG signal cable is not connected, it will directly lead to inverter overload, such phenomena to the absolute prohibition, it is liable to damage the inverter. If then there EMG signal line, carefully inspect cable is connected to reality. OK then real, no line failure, then a multimeter to check whether there EMG controller output. If and when the controller is switched, EMG signal is not output, it indicates that the controller has failed. Moreover, inverter control mode controller regardless of what type, are coasting stop mode switch.
