quantity control valve
解釋
定量控制閥-
When the governing valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod increased, meanwhile, it ' s time of rise, time to peak and the governing time all increased. at the same time, the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased
當出口節流調速系統的回油路上串接調速閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是增加的，上升時間、峰值時間以及調整時間也是增加的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。 -
This control system adopts creditable plc for real control ; it sends many simulating signals collected by old sand temperature of inlet, suction opening temperature of double disk, inner sand temperature of double disk, current of mainframe and current of fan ; meanwhile, the operation signal and switching value signal outputted by material movement transducer is inputted to switching value module of plc ; it gets evidence of water feeding after cpu account ; the operation result of cpu is outputted by switching value of plc to control unlock combination of coarse, middle and thin water feeding electromagnetically operated valve and then gets different water feeding quantity
該控制系統採用高可靠性的plc可編程序控制器進行實時控制，傳感器所採集的入口舊砂溫度雙盤抽風口溫度雙盤內砂溫主電機電流及鼓風機電流等模擬量信號直接輸入plc的模擬量採集模塊，同時加砂設備運轉信號及加砂設備物料移動檢測傳感器發出的開關量信號輸入plc的開關量模塊，由cpu獲取經運算而得到加水計算依據， cpu運算結果直接由plc的開關量輸出控制粗中細加水電磁閥的開啟組合，而得到不同的加水量。 -
Accorded to the experimental research, under different flow area of flow valve and different adjusted pressure of relief valve, conclusion that the regulation of the pressure p1, p2 in the two cylinder chambers varied with the change of step load were as follows : when the throttle valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod decreased, meanwhile, it ' s time of rise, time to peak and the governing time all decreased. while the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased
通過試驗研究得出系統在不同的流量閥開度、不同溢流閥調節壓力（進口壓力）下，液壓缸兩腔壓力p _ 1 、 p _ 2隨階躍負載變化的規律：當出口節流調速系統的回油路上串接節流閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是減小的，上升時間、峰值時間以及調整時間也是減小的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。
