当飞机主液压系统压力不足时,液压电动泵作为应急液压系统液压源,为飞机提供液压,并通过螺旋开关向主液压系统供压。此种操作方式较为复杂,在应急情况下会增加机组人员操作负担。经过对液压电动泵控制方式的分析,现提出新的液压电动泵控制方式,以期减少液压系统的故障,减轻机组人员的操作负担。
When the pressure in the main hydraulic system of the aircraft is not enough, the hydraulic electric pump acts as the hydraulic source of the emergency hydraulic system, supplies the hydraulic pressure to the aircraft and supplies the pressure to the main hydraulic system through the screw switch. This mode of operation is more complicated, which will increase the operational burden on crew members in emergency situations. After analyzing the control mode of the hydraulic electric pump, a new hydraulic electric pump control mode is proposed in order to reduce the hydraulic system failure and reduce the operational burden on the crew.
