Xinshao longhui residential high-rise water supply equipment water equipment Xinshao longhui residential high-rise water supply equipment water supply equipment China are Chinese famous brand factory outlets at competitive prices! Hotline: 15073127301 Jingli Waldo Xinshao rise frequency of water supply equipment consists of: automatic water supply equipment mainly by the frequency control cabinet, pressure sensors, pumps and other components. Frequency control cabinet by the circuit breakers, inverter, contactors, relays, PLC and other components. Frequency equipment is VVVF technology and computer control technology for water pump automatic control equipment into and combined with the water pump water mechatronic devices. The water supply pipe network equipment based on the instantaneous change in pressure and flow parameters, automatically change the number of units and the pump operating speed, constant pressure variable water supply loop regulation, so as to achieve the purpose of energy-efficient. Huadu Long back district water supply equipment water equipment : According to the changes in water users run the pump automatically adjusts the number of units and a pump speed, the pump outlet pressure constant. When the user is less than one pump out water, the control system according to changes in water has a water pump frequency adjustment operation, when the water increases the pressure drop within the piping system, when the pressure sensor to detect the signal transmitted to the microprocessor control unit, run by computer to determine, issue commands to the inverter control pump motor, the speed is accelerated to ensure that the system pressure constant, whereas when the water is reduced, so that the pump speed slows down to maintain constant pressure. When the water than a water pump when the pump is switched to the first 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 pumps running . Throughout the operation, always keep constant pressure system, the pump is always working in the high zone, both to ensure constant water supply, but also saves energy.
