過載閥值 的英文怎麼說
中文拼音 [guòzǎifázhí]
過載閥值
英文
overload threshhold-
When the electrohydraulic push rod works, if the external force suffered by the piston rod is more than the setting output torque, the piston moves to the end ; oil pressure in the oil pipeline increases rapidly to the setting value, the safety valve overflows rapidly, to achieve overload protection
電液推桿工作時,當活塞桿所受外力超過調定的輸出力距活塞運動到終點;油路中的油壓迅速增高至調定值,安全閥迅速溢流,實現過載保護。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。
