No negative pressure water supply equipment Scope: 1, there are pools of high-rise buildings, hotels and residential areas ,, towns, enterprises, new construction of living water. 2, factories, industrial and mining production water or life. 3, all kinds of water plants, water supply stations, sewage water plant, agricultural irrigation and other water supply and drainage stations. 4, high-rise, residential, centralized water supply enterprises. 5, the production, the life of the cooling water, circulating water pressure. 6 constant pressure oil, oil pipelines, oil depots, gas stations and the like. No negative pressure water equipment features: a, automatic isolation valves or throttling device (optional): used to isolate municipal water, can be arbitrarily set operating pressure, when the municipal water pressure is lower than this value, the isolation device action, switch to the water tank or pressure tank water supply. Also consider using inexpensive throttling device instead of the isolation valve, limiting the maximum water flow, inadequate water supply compensated in part by the water tank. b, water tank: Water runs all the volume is filled with water tank, because no compressed air energy storage, buffering effect of various shocks and dynamic compensation of municipal water as effective as a buffer tank. But when the municipal water pressure is too low, the water tank effluent (water) is greater than the amount of water, water storage tank volume can all be used to compensate for the lack of municipal water. During the water tank to provide compensation for the amount of water the air by vacuum suppressor automatically enters the tank, to avoid causing negative pressure to compete with suction pipe network (the so-called no vacuum suction). Water tank can be used in series with the water line. c, pressure tank: generally reinforced concrete structure, with water tank to work on the same principle, because of the large volume of municipal water supply has a good load shifting role for a variety of municipal water situation throughout the country. When the municipal water supply network for any reason during the pool without water pressure provided by a certain time of water supply sources for customers that require high reliability of water supply applications. d, pump unit: selection of the company has a non-overloading characteristics of pumps, which can be adapted to the pressure change operating characteristics over a wide range of municipal water, and does not produce overload. e, pressure tank: its role and usually twice a pressurized water supply equipment in the pressure tank the same standard product design using miniature diaphragm pressure tank, the main advantage of its packing function, automatic energy-saving equipment in favor of intelligent control. f, frequency control cabinet: a choice of full conversion technology solutions that all pumps are used frequency drag, but also be part of the inverter technology program (only one pump for frequency control drag). g, a bypass line: If the municipal water supply gas to meet the usual requirements, only the peak pressure in the water supply shortage, loadable bypass pipe so that the municipal water and pressurized water directly automatic switching operation. When non-fire state, the use of TH-F series automatic inspection of water supply equipment, complete sets of automatic fire control equipment consisting of inspection, fire pumps can do automatic inspection operation. Automatic inspection cycle for a few hours to several hundred hours, optionally, the clock cycle starts automatically with manual inspection procedures and inspection functions. Digital intelligent fire patrol inspection of fire control cabinet controller will detect the main circuit after confirming normal, one by one driven fire pump to make low-speed operation, when the drive power is very small, about the percentage of the pump motor power rating about one, so significant energy saving. Due to the low speed, so it will not pressurized water supply pipe network. If you run the command while receiving the fire inspection, the local control unit will immediately interrupt polling operation, the control device to power-frequency-driven fire pump into the fire command is run. Only in the next period and no inspection when the fire occurred, began running a new inspection process. When the inspection, if the pump fails fault alarm information will be given. When an input overvoltage, undervoltage, phase, output over-current, TH-F Series controller will issue a warning message to the fire center a short circuit. This result ensures automatic inspection of the fire pump will not rust, rust phenomenon, the fire water supply equipment "idea that day, military forces while" a reality. The device also has a standby pump automatically swap, when the main pump failure, the standby pump automatically input. Standby power automatic mutual investment, when the main power fails, the standby power is automatically put into other functions, TH-F series digital controllers intelligent fire patrol fire automatic control equipment will patrol all of the above features provide remote data, image monitoring, fault alarm, message printing.
