Abstract
PURPOSE: To cope with it forthwith in case where any abnormality happens in such a way that in concurrence of detecting the working condition of the hydraulic system with introducing all of this into an arithmetic unit, it is brought into comparison with the normal condition, and in case of abnormality, alarms will go off.
CONSTITUTION: Respective detections are made for oil level in a hydraulic tank 1 with use of an oil level gauge 16 while for delivery pressure of a hydraulic pump by a pressure detecting material 7, and, respective property curves are made into funcitons in all the behaviors of the hydraulic system, which are comparingly operated by an arithmetic unit 8 as well as signals from a pumping delivery gain setter 19 and a pressure function setter 20, upon finding any abnormality, abnormality alarms will go off by the arithmetic unit 8. Such as this, since any abnormality is displayed by the abnormality alarms in all the working condition of the hydraulic system, upon finding any abnormality, immediate countermeasures for it can be done along with shirking personal accident or material loss
