ABSTRACT:
If a determination is made by a pressure gradient comparison means 24 that gradient of the rise in the pressure in an accumulator calculated by a pressure gradient calculating means 21 and realized during the operation of a pump is lower than a predetermined level, occurrence of an abnormal condition of the pump or a motor is determined. If a pressure gradient comparison means 24 determines that the gradient of pressure depression of the hydraulic pressure in the accumulator realized after the operation of the pump has been interrupted is higher than a predetermined value, occurrence of an abnormal condition which is leakage of solution is determined. If determination of the abnormal condition is sequentially made predetermined number of times, an abnormal-condition deciding means 28 decides occurrence of an abnormal condition, and then produces an output to an alarm-signal generating means 29.
