Examples
- The effect of return oil pressure on hydraulic system with differential pressure control valve
回油压力对具有差压式配压阀的液压系统的影响 - The machine has return oil cooling equipment , and can control temperature of oil in order of assurance machine working normally all the time
机器并带有回油冷却装置，可以有效地控制油温、保证机器连续正常运行。 - 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
本文以单出杆液压缸为执行元件的出口节流调速系统为研究对象，在其回路上分别串接节流阀和调速阀，当负载发生阶跃变化时，对液压缸两腔压力p _ 1 、 p _ 2的影响进行了试验研究。 - 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
当出口节流调速系统的回油路上串接调速阀时，随阶跃负载的增加，在相同流量阀开度、相同溢流阀调节压力的情况下，液压缸有杆腔压力p _ 2 ( t )的超调量是增加的，上升时间、峰值时间以及调整时间也是增加的；液压缸无杆腔压力p _ 1 ( t )的超调量是增加的。 - 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
通过试验研究得出系统在不同的流量阀开度、不同溢流阀调节压力(进口压力)下，液压缸两腔压力p _ 1 、 p _ 2随阶跃负载变化的规律：当出口节流调速系统的回油路上串接节流阀时，随阶跃负载的增加，在相同流量阀开度、相同溢流阀调节压力的情况下，液压缸有杆腔压力p _ 2 ( t )的超调量是减小的，上升时间、峰值时间以及调整时间也是减小的；液压缸无杆腔压力p _ 1 ( t )的超调量是增加的。
