A hydraulic circuit system with an abnormality diagnosis function is provided with: at least one positive displacement pump; the hydraulic circuit is connected with the pump; a downstream-side sensor that detects a state quantity of the hydraulic fluid flowing downstream of the hydraulic circuit; and an abnormality diagnosis device that determines an abnormality in the hydraulic circuit on the basis of a first state quantity of the hydraulic fluid discharged from the pump and a second state quantity of the hydraulic fluid detected by the downstream sensor.
一种带异常诊断功能的液压回路系统,其具备:至少一个容积式的泵;液压回路,其与泵相连;下游侧传感器,其检测在液压回路的下游侧流动的工作液的状态量;以及异常诊断装置,其基于从泵吐出的工作液的第一状态量和由下游侧传感器检测的工作液的第二状态量,判断液压回路的异常。
