穩(wěn)流罐 Steady flow tank
無負壓控制
系統(tǒng)設(shè)定一恒定壓力值，如果管網(wǎng)壓力高于設(shè)定壓力值時，壓力變送器將管網(wǎng)壓力反饋給變頻控制柜，自來水可通過直供管路直接到達用戶管網(wǎng)對用戶進行供水。穩(wěn)流罐當(dāng)市政管網(wǎng)壓力變化或用戶管網(wǎng)用水量變化使管壓力低于設(shè)定壓力時，壓力變送器將管網(wǎng)壓力反饋給變頻控制柜中的PlD控制器，通過PlD控制器調(diào)整變頻器的輸出頻率，啟動水泵機組并調(diào)節(jié)水泵轉(zhuǎn)速保持恒壓供水；如果不能滿足供水要求時，則控制柜將控制多臺工頻泵的啟停和變頻泵的轉(zhuǎn)速，從而達到恒壓變量供水的要求。
無負壓設(shè)備采用微機變頻技術(shù)和有效的負壓處理技術(shù)實現(xiàn)疊壓供水。具體如下：該設(shè)備通過穩(wěn)流罐的真空補償系統(tǒng)及全封閉結(jié)構(gòu)實現(xiàn)了與自來水管網(wǎng)的直接串接，并且克服了對管網(wǎng)的不良影響。該設(shè)備通過管網(wǎng)壓力表、真空抑制器及穩(wěn)流補償器中的檢測裝置采集穩(wěn)流罐內(nèi)的真空度及水位信號，實時反饋，通過微機控制真空抑制器及穩(wěn)流補償器中的特殊裝置動作，抑制負壓產(chǎn)生，保證穩(wěn)流罐消除負壓該設(shè)備不對城市管網(wǎng)產(chǎn)生影響。

Steady flow tank
No negative pressure control
The system sets a constant pressure value, if the pipe network pressure is higher than the set pressure value, the pressure transmitter will feed back the pressure of the pipe network to the frequency conversion control cabinet, and the tap water can directly reach the user pipe network through the direct supply pipe to supply water to the user . Steady flow tank When the municipal pipe network pressure changes or the user pipe network changes in water pressure pipe pressure is lower than the set pressure, the pressure transmitter pressure feedback to the PID control cabinet PID controller, adjusted by the PlD controller Inverter output frequency, start the pump unit and adjust the pump speed to maintain constant pressure water supply; if you can not meet the water requirements, the control cabinet will control multiple frequency pump start and stop and frequency conversion pump speed, so as to achieve constant pressure variable water supply Request.
Negative pressure equipment adopts microcomputer frequency conversion technology and effective negative pressure treatment technology to realize the laminated water supply. The details are as follows: The device realizes the direct connection with the water pipe network through the vacuum compensation system of the steady flow tank and the totally enclosed structure, and overcomes the adverse influence on the pipe network. The device collects the vacuum degree and the water level signal in the steady flow tank through the pressure gauge in the pipe network, the vacuum suppressor and the detecting device in the steady flow compensator, real-time feedbacks, and controls the special devices in the vacuum suppressor and the steady flow compensator by the microcomputer Action to suppress negative pressure to ensure steady flow tank to eliminate negative pressure The device does not affect the urban pipe network.
