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.

　　整个供水系统包括恒压供水和流量控制，采用PLC、变频器、压力变送器、电液比例流量控制阀和电磁流量传感器组合控制方案。由PLC、变频器和力传感器组合控制方案来控制高压水箱供水压力,变频器,PLC控制变频调速装置,根据实际的液压压力传感器检测到的变化,不断调整泵的速度,通过调整流来实现恒定的水ffi的目的:在恒水压条件下，再由PLC、电液比例流量控制阀和电磁流量传感器组成闭环控制系统，精确控制水的流量，从而满足石膏墙板生产流量的需要。

　　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.

　　该设计方案可以精确和稳定的水箱水位,水的实时补偿的变化,水泵连续在低速运行状态,而不需要频繁起停操作,有利于延长维修周期,而无需人工干预,完全消除水锤现象,实现了自动恒压供水和流控制,可满足石膏生产水箱供水的要求,和消除问题在传统的供水系统中,还可以节省电力,该系统采用闭环控制,自动补偿用水量的变化,提供的软启动功能变频器气体可以消除触电和机械冲击,延长机械和电气设备的使用寿命。

　　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.
