No negative pressure water supply equipment mainly Scope 1, living water: as new, expanded living quarters living water. Especially in high-rise overlying water supply. 2, Water Supply Improvement: If the household water and commercial building water tank with water and air pressure supply frequency transformation. 3, Fire Water supply: water supply for fire such as various new projects. 4, recycling water and water systems: such as boilers and air conditioning, and other recycled water and water systems. 5, secondary pressurized water pipe network station: such as water supply pipe network booster pump station. 6, commercial buildings: such as hotels, office buildings, department stores, large sauna and so on. 7, the manufacturing industry: such as manufacturing, washing equipment, food industry, factory. 8, public places: such as hospitals, schools, stadiums, golf courses, airports. 9, Irrigation: such as parks, playgrounds, orchards, farms and so on. ★ parameter range of secondary water supply pressure range: 0.3MPa ~ 2.0 MPa secondary water flow range: 2m3 / h ~ 1000 m3 / h Ambient temperature: 4 ℃ -40 ℃. Relative Humidity: <90% (20 ℃). Medium temperature: 0 ℃ -70 ℃. Power Frequency: 50Hz ± 5%. Supply voltage: 380V ± 10%. Altitude: less than 1000m. Equipment operation site should be no conductive or explosive dust, non-corrosive metal or destroy the insulating gas or vapor. ★ Device Overview CFXR brand pipe network overlying water supply equipment is Backflow devices (according to their needs), steady flow tank, anti-vacuum device, water pump, pressure limiting protection device, the expansion tank (according to their needs), control instruments, control cabinets, valves, piping systems, matching accessories and other components, water from the water supply pipe network directly, through the pressure sensor detects the pressure, the test value and set value, calculated in municipal water pipe network pressure based on the need to increase the pressure value, determine the number of units and the pump into the inverter output frequency, adjust the pump speed to match the curve of constant pressure water supply or transformer supply. Pipeline overlying water supply equipment to maximize use of the municipal water supply of raw water pipe network pressure on municipal pipe network does not produce negative pressure, steady flow with stainless steel sink and fittings, reducing secondary pollution of water, is a new generation of energy-saving products field of water supply . ★ Features 1, automatically eliminate negative pressure systems and municipal water supply pipe network directly overlying water without causing negative pressure municipal pipe network. Group and the world famous enterprises, using high quality materials and accessory devices, by absorption, improvement, independently developed a versatile, able to provide cutting-edge level of precision control equipment, integrated has reached world leading level. 2, energy-saving equipment at runtime laminated with municipal water pressure, the pressure in the original pipe network superimposed on the basis of the required pressure difference, difference how much fill, make full use of the residual pressure pipe network, the system automatically adjusts the number of operating pumps or adjust the pump speed to achieve high efficiency point has been run. When the water pressure to meet the design pressure, the pump energy-saving sleep state. Therefore, significant savings in operating costs, in line with national energy requirements. 3, the pressure control device in real time via the pressure outlet pressure sensor, the detection value and set value, calculated in the municipal water pipe network I need to increase pressure on the basis of the pressure value, determine the number of units and the pump into the inverter output frequency adjust the pump speed to achieve constant pressure water supply or laminated layers of control transformer supply. 4, high degree of automation systems with manual start and stop, automatic start stop mode, set aside remote operator interface, the standby pump automatically switches, pressure control (constant voltage / transformer), high and low voltage protection, phase protection, leakage protection, overload protection, thermal protection, trip protection function, the system fully automatic operation without special duty, HMI, remote adjustment, monitoring and maintenance. 5, the health system sealed operation, foreign bodies can not enter the system itself, not in direct contact with the air. Such as anti-vacuum device startup, membrane filtration device will block the bacteria in the air, do not enter the system, to prevent secondary pollution of water. Steady flow tank and the main flow passage components are made of 304 stainless steel to ensure water and sanitation to meet the people growing demands for drinking water, but also in line with international health standards wading.
