No vacuum in the original basis, Hanson innovation, has developed a high efficiency and low noise frequency secondary water supply equipment. HBW high efficiency and low noise frequency secondary water supply equipment to achieve the relevant non-vacuum, primarily through computer control system combined with real-time control action on the steady flow compensation system, bistable pressure compensating controls and vacuum suppressor to achieve. Where the steady flow compensation system including pressure and liquid level control device used to prevent a re-action suction unit, this unit has a warning of heavy action function, that is when there is a tendency to form negative pressure, the computer control system through joint bistability state pressure compensating controls to compensate for lack of water pressure at this time, the vacuum is no negative suppressor to protect the last heavy, twin-piston vacuum suppressor protection with 300 large level of protection of the pipeline pressure. Head over filtration devices, mainly to complete the final elimination of non-negative function. Triple no negative measures to prevent both joint and independent, mainly through computer control to maximize efficiency and low noise frequency most Hanson secondary water supply facilities in the original general supply equipment technology combines efficiency and noise reduction technology, water supply equipment reflects his more professional and more customers to consider only one side had no negative basis. Secondary water supply equipment works: Works equipment are adjusted automatically run the pump station number and a water pump speed changes according to the user, so that the pump outlet pressure remains constant. When the user less than a water pump out the water, the control system according to changes in water has a water pump frequency adjustment operation, when the water increases the pressure drop in the pipe 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, so that the pump speed slows down to maintain constant pressure. When the water is greater than a water pump, the first pump is switched to 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 water pressure smooth control technology. Outlet pressure control system has a smooth control technology. If there is no smooth control technology, equipment is often the case there will be pressure overshoot. In addition and subtraction water pump or large changes occur, the pressure fluctuation is relatively large. After smoothing control technology, the system can automatically control the acceleration and deceleration speed based on actual feedback pressure, the pressure system more stable. 5. saving footprint, saving installation work: do not build pools, do not install water tanks, equipment shipped to the site, the user's water inlet and outlet pipe with no negative frequency of water supply equipment butted, simple construction, construction period short, small footprint. 6. save manpower, material: Zhangjiajie secondary water supply equipment using water quality there is no pollution, no need to install disinfection equipment, further saving investment. Very economical to use, because there is no pool (box), saving the cost of regular disinfection cleaning. 7. Advanced control system: designer inverter, man-machine interface control can be installed according to customer requirements, accurate, clear, real-time display of water pressure, water pressure, set pressure, the pump current, frequency and other operating parameters and running, while dynamic images and real-time image display. Automatic intelligent control and management, friendly man-machine dialogue, simple operation and reliable performance. ? Pro, specific price please call.
