1．液压系统的泄漏量液压系统的泄漏量通常包括两种，即瞬时泄漏量和过程泄漏量。所谓瞬时泄漏量，是指在机械工作中的某一时刻整个液压系统的总泄漏量，用AW／t）表示。对于一个正常运转的工程机械液压系统，其瞬时泄漏量通常保持在某一定值附近。如果某一时刻，系统的瞬时泄 1. Hydraulic System Leakage Hydraulic system leakage usually includes two kinds, namely, the amount of instantaneous leakage and process leakage. The so-called instantaneous leakage, refers to the total leakage of the hydraulic system at a certain moment in the mechanical work, with AW / t) said. For a normal operating hydraulic system of construction machinery, the instantaneous leakage is usually kept in the vicinity of a certain value. If a moment, the system instantaneous vent
