Shangzhou negative pressure pipe network the overlying water supply equipment product performance WWG series the Shangzhou no negative pressure water supply pipe network laminated device (pipe network regulator pressurized equipment) indicators are as follows: flow range: 2.4m3/h-300m3/h ; pressure range: 0MPa-1.6MPa; (adjustable) speed range :0-1450r / min or 0-2950r/min; (adjustable) (pipe network adjustment the pressurization equipment) is the use of advanced design technology developed its own New water supply equipment. To with variables constant pressure notable features of high precision water pressure, that is the premise of constant pressure, the flow rate from zero to maximum work flow within the water supply pressure range within ± 0.01MPa to eliminate the water pipe network the phenomenon of negative pressure, improve the reliability of the domestic water supply system; small footprint, save construction investment, installation easy maintenance; ideal water supply equipment is suitable for use in industrial and civil life of the system. Pipe network WWG series Shangzhou no negative pressure the overlying water supply equipment (pipe network regulator pressurized equipment) key indicators are as follows: flow range: 2.4m3/h-300m3/h;. Pressure range: 0MPa-1.6MPa; (adjustable) speed range :0-1450r / min or 0-2950r/min; (adjustable) Shangzhou no negative pressure water supply pipe network laminated equipment selection according to the the user tap water pipeline pressure and flow, the user's actual water usage, building height data to determine the device table with the regulator volume is estimated in the case in accordance with the tap water flow to meet the requirements, if the water pipe is very thin, the flow can not meet the owner of the water requirements of the water peak period, regulators need to be recalculated The volume recommended companies are as follows: the V volume = (Q the showing-Q into) △ t ??Q Q = water users maximum water peak period of the day t = duration of peak water = one day for the high water peak of tap water into the water. Shangzhou no negative pressure water supply pipe network laminated equipment the Shangzhou no negative pressure water supply equipment, complete sets of equipment generally by the buffer tank, water pump, pressure tank control cabinets and control instruments composed of pipe network layers, each part described as follows: a, buffer cans: the pressure tank is connected to the device at the entrance, referred to the buffer tank, running water supply tank partial volume of compressed air, rely on compressed air energy storage, has good mitigation to eliminate the role of the various mutations impact, while the municipal The water supply has a certain dynamic compensation effect. Different structure of the buffer tank, diaphragm buffer tank made of natural rubber diaphragm material, fully enclosed more conducive to maintaining water quality standards, ordinary steel buffer tank wall is coated with anti-corrosion coatings to meet the health standards, but when qi with the outside world air contact. The buffer tank can be connected in series, and accepts (and out of the water for the same pipe as branch and municipal piped shown in Figure 2-2), the pump unit: choose the company with non-overload characteristics pumps, their operating characteristics can be adapted to the pressure change within the larger range of the water does not produce overload. c, Shangzhou negative pressure pipe network laminated pressure tank water supply equipment: its role usually twice a pressurized water supply equipment in the pressure tank is the same, standard product used in this series diaphragm micro-pressure tank, the main use of the holding pressure function favor equipment intelligent automatic energy-saving control. d, Shangzhou negative pressure pipe network laminated water supply equipment, frequency conversion control cabinet: inverter control system can be used, that all pumps are used to drag VVVF inverter control system (the sample standard product only pump can also be used for VVVF drag). e, the Shangzhou no negative pressure water supply pipe network laminated equipment bypass line: If the municipal water supply is usually able to meet the pressure requirements, only in peak water pressure is insufficient, loadable bypass line allows municipal drop-down water supply and pressurized water supply for automatic switching operation. (1) when the high pressure of the municipal pipe network, Shangzhou no negative pressure water supply pipe network laminated device is in shutdown state, municipal water over the buffer tank, the bypass pipe water pipe network to the user directly. (2) When the municipal pipe network undervoltage, Shangzhou no negative pressure water supply pipe network laminated device automatically starts in the original water supply, water pressure on the basis of frequency control supercharger (constant voltage) is much worse, complement the principle of "supercharger, so 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) Shangzhou no negative pressure the pipe network laminated water supply equipment operation, partial volume of buffer tank for compressed air (pressure municipal water pressure), thus some pressure potential storage can rely on this storage can greatly slow down the various impact on municipal water, and dynamic clipping compensation of municipal water supply at the same time. When the pressure on municipal services decreased from P2 to P1, the maximum compensation amount of water and the total volume of the buffer tank buffer tank relationship: V = (1-P1/P2) V total = KV total V # - peak water Municipal pressure from P2 dropped the P1 during water tank given compensation amount of water (m3) the lowest peak P1-municipal water supply pressure (absolute) P2-municipal water supply before the peak of the pressure (absolute pressure) V total - the total volume of the water tank (m3) Example: water peak period, municipal water pressure reduced from 20mH2O to mH2O, given the water tank in the compensation of water, V # = (1-15/30) V = 0.5V total (m3), the total volume of of 50%. Obviously, this is an effective dynamic compensation effect, if the pressurization equipment for all users with this role in compensating the overall municipal water can play a certain load shifting effect, during the height of the pipe network pressure is not As for the drops too low. (4) control instruments with buffer tank can be automatically shut down when the municipal pipe network pressure below the set lower limit (prohibit running) to prevent excessive pumping municipal water and prevent the pumping run.
