Beautiful supply of Xishuangbanna fully automatic constant pressure water supply equipment features, Sham Tseng constant pressure water supply equipment requirements, take a step backward Changsha Tong Tak Water Supply Equipment Co., Ltd. (no negative pressure frequency conversion water supply equipment, constant pressure water supply system, no water tower equipment, senior secondary water supply equipment, fire regulated water supply equipment)??????????????????????????????????????? ?????????????????????????????????????????????????? ??????????????????????????????? main purposes: According to the pipe network pressure changes, automatically adjust the pump speed and run the station number, the water supply network to maintain the set pressure and flow required to achieve the purpose of the improvement of water quality and energy efficient; 1, the increase in the pump control process, when the amount of water increases, the water pressure drops, the inverter output frequency up to 50Hz when still insufficient water pressure, after a short delay, the M1 switches to power frequency inverter output frequency is rapidly reduced to 0, then M2 into frequency operation. M2 has reached the rated frequency and the water pressure is still low, repeat running process pumps M2 from the inverter drive running at full speed by the working frequency of the power supply, inverter-driven water pump the M3 frequency conversion run, so the constant pressure in the set value. 2, less pump control flow, water use reduction, water pressure rise, the inverter output frequency is below the lower limit, but the pipe network pressure is still too high, each pump will first open first stop quit running sequentially; down the pump switching process, When pumps run after a certain time (the time can be set), then automatically switch to the next pump, to avoid long-running loss, and also to avoid long-term rust does not work. The automatic fault switching function: When a pump fails, the next stage pump automatically put into operation, will not affect the system of water supply. 5, perfect protection function: control cabinet has perfect protection function, the pump motor phase loss, short circuit, grounding, undervoltage, overcurrent, overvoltage, overheating, overload and fault alarm accurately. 6, complete fault tolerance: control cabinet with automatic inverter manual variable frequency and the manual power frequency function, can ensure maximum water supply, even if the frequency converter and a programmable logic controller all the damage, still allows the pump frequency operation, securing water . Automatic frequency conversion water supply equipment product performance features 1RBG series for industrial and civil water supply equipment, which can be a single inverter control multiple pumps, pumps cycle start. 2. RBG Series shared water supply equipment for life and fire, it can usually low constant pressure (pressure) to ensure domestic water supply. Immediately after receiving the fire signal into a high-pressure water supply (pressure) way to meet the needs of the fire. In addition, the Series devices also have a fire pump timing automatic inspection function. This product not only constant voltage automatic water supply, and energy-saving effect is very significant, the saving rate of 30%. Automatic control, no special duty. Output water pressure is very stable and does not produce secondary pollution. 6 high reliability, perfect protection function. Automatic frequency of water supply equipment Details RBG automatic frequency conversion water supply equipment for industrial, public facilities and civil construction life, production, fire water system, hot water boilers and pipes fixed pressure system. Constant pressure water supply system, technical instructions: 1, flow adjustment range, 0 to 5000m3 / h 2, the pressure adjustment range, 0 to 2.5Mpa 3 to control the motor capacity, 0.37 ~ 250KW 4, pressure regulator accuracy <+-0.01Mpa 5 pressure stabilization time, _________________________________________ <%
