ようにしたことを特徴とする油圧源。In a hydraulic source that supplies hydraulic pressure, there is a sampling circuit that samples a predetermined amount of hydraulic oil from the outlet of the oil tank, a measurement circuit that measures the water content of the hydraulic oil sampled by this sampling circuit, and a measurement circuit that measures the water content of the hydraulic oil sampled by this sampling circuit. a judgment circuit that compares the determined value with a pre-stored standard value, a valve opening/closing circuit that controls the supply of hydraulic oil to the outside based on the signal generated from the judgment circuit, and a display that indicates abnormality in water content. A hydraulic power source is characterized in that it has a circuit and is capable of supplying hydraulic oil to the outside while constantly checking that it has a water content exceeding a standard value.
