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。 -
Presents the authors ' renewed ideas from the concerns on a series of related field tests and researches in recent years, stressing that the long - held concept heat metering simply means heat meter plus thermostatic valve should be updated
摘要提出了基於近幾年對相關的工程實測與研究的跟蹤關注所得出的深化的認識，著重指出要從「熱量表加溫控閥即計量供熱」的狹隘觀念中解脫出來。 -
Used the metering - out control system in which the hydraulic cylinder was the executive element as research object in this thesis, the experimental research about the effect on the pressure p1, p2 of the hydraulic cylinder chambers when series - connecting throttle valve or governor valve on the return oil - line under the step load changing have made
本文以單出桿液壓缸為執行元件的出口節流調速系統為研究對象，在其迴路上分別串接節流閥和調速閥，當負載發生階躍變化時，對液壓缸兩腔壓力p _ 1 、 p _ 2的影響進行了試驗研究。 -
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。 -
By employing intelligent control, the pressure pump and electro - hydraulic valve are controlled by the host computer, therefore the influence on metering accuracy, which caused by human factors is eliminated and the metering error is reduced. scientificalness and automation of the metering management system is implemented by using local area network
主機對加壓泵和電液閥進行智能控制，消除了人為因素對計量精度的影響，減小了計量誤差，利用局域網技術實現計量管理的科學化、自動化、網路化。
