The quantity of gypsum powder is controlled by PLC. The load cell converts the quantity of gypsum powder into electrical signal and sends it to PLC. Then PLC controls the electro-hydraulic proportional flow control valve to regulate the water flow. The electromagnetic flow sensor is installed at the outlet to detect the flow, so that the system can supply water stably.

　　整個供水系統包括恒壓供水和流量控制，采用PLC、變頻器、壓力變送器、電液比例流量控制閥和電磁流量傳感器組合控制方案。由PLC、變頻器和力傳感器組合控制方案來控制高壓水箱供水壓力,變頻器,PLC控制變頻調速裝置,根據實際的液壓壓力傳感器檢測到的變化,不斷調整泵的速度,通過調整流來實現恒定的水ffi的目的:在恒水壓條件下，再由PLC、電液比例流量控制閥和電磁流量傳感器組成閉環控制系統，精確控制水的流量，從而滿足石膏墻板生產流量的需要。

　　The whole water supply system includes constant pressure water supply and flow control, adopting PLC, frequency converter, pressure transmitter, electro-hydraulic proportional flow control valve and electromagnetic flow sensor combined control scheme. The combined control scheme of PLC, frequency converter and force sensor is used to control the water supply pressure of the high-pressure water tank. The frequency converter and PLC control the frequency conversion speed regulating device. According to the change detected by the actual hydraulic pressure sensor, the pump speed is constantly adjusted, and the constant water FFI is realized by adjusting the flow. Under the condition of constant water pressure, the PLC, electro-hydraulic proportional flow control valve and electromagnetic flow sensor are used to close the water supply pressure The loop control system can precisely control the flow of water, so as to meet the needs of the production flow of gypsum wallboard.

　　該設計方案可以精確和穩定的水箱水位,水的實時補償的變化,水泵連續在低速運行狀態,而不需要頻繁起停操作,有利于延長維修周期,而無需人工干預,完全消除水錘現象,實現了自動恒壓供水和流控制,可滿足石膏生產水箱供水的要求,和消除問題在傳統的供水系統中,還可以節省電力,該系統采用閉環控制,自動補償用水量的變化,提供的軟啟動功能變頻器氣體可以消除觸電和機械沖擊,延長機械和電氣設備的使用壽命。

　　This design scheme can accurately and stably water level of water tank, real-time compensation change of water, continuous low-speed operation of water pump without frequent start and stop operation, which is conducive to prolonging maintenance cycle without manual intervention, completely eliminating water hammer phenomenon, realizing automatic constant pressure water supply and flow control, meeting the requirements of water supply for gypsum production water tank, and eliminating problems in traditional water supply system It can save power. The system adopts closed-loop control to automatically compensate the change of water consumption. The soft start function of inverter gas can eliminate electric shock and mechanical shock, and extend the service life of mechanical and electrical equipment.
