VVVF life advantages of water supply equipment, advanced technology and property management costs low, no negative pressure water supply equipment to vacuum suppression technology, fluid control technology and intelligent inverter technology and many other advanced technologies to optimize the integration to achieve automatic control can be unattended . No negative pressure water equipment and water pipe network directly connected in series, the regulator, energy conservation, health, safe and reliable operation. 2, health non-polluting: the device is fully sealed structure, bacteria and dust will not enter the system; avoid algae breeding prevent the water secondary pollution and water supply of water pollution problems, users use tap water to meet national health standards. 3, the energy saving effect is remarkable: fully enclosed structure runs to avoid the infiltration, run, run, drip, drain phenomenon directly connected in series with the water pipe network, you can take full advantage of the original tap water pressure, much worse to make up the number, tap water meet request the device to stop working. Most of the time no negative pressure water equipment running at a lower frequency, and less power consumption. Inverter technology, further energy saving, energy saving is generally up to 50% or more. Small footprint, simple installation, investment in the credibility of the first, without repair cistern or water tank savings civil resources; without pressure from zero, so less equipment selection, equipment investment decreased; water pollution, not purification equipment, saving investment. Can take full advantage of the pressure of the water pipe network, energy consumption, save the day-to-day expenses of electricity. Sewage tank, water tank, saving the cost of regular cleaning clothes disinfection. Reliable operation: no effect on the water pipe network, the device by adjusting the tank no negative pressure automatically adjust the pipeline pressurized water supply will not produce negative pressure on the original pipe network, does not affect the other users of the normal water. 6, power outages kept the water: equipment, piping and user of a public water supply pipe network directly connected, in the event of a power outage, and strengthen the pumps stop working, but building low-level users still maintain water. Frequency conversion constant pressure water supply equipment features a automatic isolation valve or throttling device (optional): used to isolate the municipal water, operating pressure can be set arbitrarily, municipal water pressure is lower than the value, the isolation device action switch to the water tank or pressurized pond water supply. May also consider using cheap throttling device instead of the isolation valve to limit the maximum influent flow, inadequate water supply in part by the water tank compensation. b, the water tank: feedwater run tank entire volume is full of water, compressed air reservoir, the cushioning effect of the various shocks and dynamic compensation effect than the buffer tank of the municipal water. However, when the municipal water pressure is too low, the water tank effluent (water supply) is greater than the amount of water, the tank storage volume can all be used to compensate for the lack of municipal water. Automatically enters the tank during the water tank to provide compensation for the amount of water to the air by vacuum suppressor can cause depression suction avoid compete pipe network (the so-called no negative pressure suction lift). The water tank can only series with the water pipe. c, confined pools: generally reinforced concrete structure with water tank works, has good load shifting role of the municipal water supply because of its large volume, apply to the municipal water situation across the country. By pressure pond when the municipal water supply network for any reason without water during a certain time of the water source, suitable for occasions require highly reliable water supply to customers. d, the pump unit: choose the company with non-overload characteristics pumps, its operating characteristics can be adapted to a wide range of municipal water pressure changes, and does not produce overload. e, pressure tank: usually 2 times a pressurized water supply equipment in air pressure tank the same standard product design, diaphragm miniature pressure tank, the main use of the holding pressure, favor the intelligent automatic energy-saving control. f, frequency control cabinet: the option of using full inverter technology program, that is, all the pumps are adopting converter, inverter technology program (only one pump the VVVF drag) can be used also. g, a bypass line: If the municipal water supply is usually to meet the moisture requirements, only insufficient pressure in the water supply peak load bypass line, the of direct municipal water supply with pressurized water supply automatically switches run. TH-F series automatic inspection of complete sets of water supply equipment, the use of non-fire state fire and automatic inspection control equipment, fire pump automatic inspection run. Automatic inspection cycle for a few hours to hundreds of hours of optional cycle clock automatically start the inspection program and has a manual inspection. Patrol when the digital intelligent the fire patrol controller be the main loop of the fire control cabinet for testing to confirm the normal by-station driven fire pump so that low-speed operation, the drive power is small, about the percentage of the rated power of the pump motor one of about significant energy saving. Low speed, so it will not pressurized water supply network. Fire run commands received in the inspection, the control device will immediately interrupt patrol run and control equipment will be put into the fire command run-frequency-driven fire pump. Only to the next inspection cycle and no fire incident began when a patrol running. Inspection, pump failure given fault alarm information. When an input overvoltage, undervoltage, phase loss, output over-current, short-circuit TH-F Series controller will alarm information to the fire center. The automatic inspection results to ensure that the fire pumps will not rust, rust phenomena, "the idea that day, used for one day become a reality, so that the fire water supply equipment. The device also has active and standby pump automatically swap, when the main pump failure, the standby pump automatically invested. Primary and backup power automatically each vote after when the main power fails, the standby power automatically input function, TH-F Series digital intelligent fire patrol controller consisting of fire control devices All of these features will provide remote data transmission automatic inspection image monitoring, fault alarm information Print function. Frequency conversion constant pressure water supply equipment frequency conversion constant pressure water supply equipment to run partial volume of buffer tank for compressed air (pressure municipal water pressure), thus some pressure potential storage rely on energy storage can be significantly slowed the various shocks of municipal the impact of the water, while the municipal water supply dynamic clipping compensation. When the pressure on municipal services decreased from P2 to P1, the buffer tank to provide the maximum compensation amount of water buffer tank volume relationship: (1) V # = (1-P1/P2) V = KV total V # - peak water municipal pressure is reduced from P2 to P1 during the period of the compensation of the amount of water (m3) in the water tank minimum peak P1-municipal water pressure (absolute pressure) the P2-municipal water supply before the peak of the pressure (absolute pressure) V total - the total volume of the water tank (m3) (2) when the municipal pipe network undervoltage, equipment start automatically, not water pressure on the basis of original the VVVF supercharger (constant voltage) water supply, because it is "much worse, make up the number of" principles supercharger so in the full flow range that meet the needs of the user constant pressure water supply, while achieving a highly efficient energy-saving operation. Airtight buffer tank for quite some piping during operation, the fresh health unsolicited Miao continuous flow water tank, and will not be subjected to external contamination. (3) When the high pressure of the municipal pipe network when the device is in shutdown state, municipal water over the buffer tank, the bypass pipe water supply pipe network to the user directly. ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????
