Flow range: 6-300m3 / h Head range: 30-200m Working Pressure: ≤2.0mpa Scope: HWG type fire regulator pressurized water supply equipment for any lack of water pressure areas. ■ new residential or office buildings and other domestic use. ■ Lower water pressure can not meet the fire water. ■ transformation of the original pressure water supply equipment. ■ You must build the pool, you can use non-vacuum equipment and pool shared water supply, further energy saving. ■ large water booster pump station in the middle of the water plant. ■ industrial and mining production, domestic water and so on. To ensure the fire pump standby time, meet fire extinguishing equipment emergency use. 2. mainly used in petrochemical, natural gas, power, textile cotton, docks, aviation, warehousing, high-rise building fire service and other industries 3. foam extinguishing system can be used for water vessels, tankers and fire ships at sea and other occasions. 4. Can be used to directly extract the municipal water supply for fire water supply pipe network occasions; 5. Can be used in life, fire water supply equipment, combined with a set of applications; 6. water pressure for fire protection, fire inspection and other special requirements occasions. 1, the equipment and the fire control center linkage, automatically enters the fire the fire state, and with the linkage feedback interface. 2, can be used to start the fire pump start-frequency direct, self-coupling voltage starting, star delta buck starts, thyristor soft-start control, constant pressure control, etc., to meet different requirements. 3, with overvoltage, undervoltage, overcurrent, short circuit, phase, water shortages, fault alarm and protection functions. 4, Fire Lord, spare pump with mutual backup function, when the main pump failure standby pump automatically put into work. 5, according to the user needs to install dual power switching function, or reprovision separate dual power switch cabinet, main and backup power can be automatically or manually switch, when the main power outage, BZT, when the main power is restored, spare Power automatically exit. 6, can be generated in accordance with the requirements of the user-frequency or low frequency automatic inspection function automatic inspection function, when the main pump inspection by one start running, stop the pump faulty alarm to avoid fire pump does not run long bearing corrosion, electrical damp, impeller stuck fault, to ensure that equipment is in good condition. Fire inspection process received signals automatically exit polling state, entered the fire running. Automatic drain valve open time-frequency inspection to ensure that the fire pipe network does not overpressure. 7, the device can also be an additional building automation (BA) interface, and the terminal computer networking, computer RMON I plant the fire pump has the following characteristics: compact structure, high degree of three, pressure, wide flow range, the pump Run gentle curve, in line with the characteristics of fire water, high-precision machining. Xiang can complete diaphragm pressure tank, also can be equipped with automatic qi pressure tank. When supporting the diaphragm tank, has a particularly simple device structure and simplify control systems, pressure control instruments installed in a special buffer damping cylinder, in order to maintain long-term reliable use. When matching automatically fill the tank without air compressor, nitrogen inflator bottle, can automatically adjust the ratio of air to ensure the proper water, efficient use of the total volume of the pressure tank, level gauge can be installed at any time observing system conditions.
