Abstract:
1. A lubricant system comprising: a hydraulic pipeline; a plurality of pumps arranged parallel to the hydraulic pipeline; a plurality of motors, each driving one of the pumps; an error detector detecting a presence or absence of an error in an operating state of each of the motors; a pressure loss addition unit that increases pressure loss in the hydraulic pipeline; and wherein the pressure loss addition unit increases pressure loss when an error is detected in at least one of the motors by the error detector, wherein when an error is detected in at least one of the motors, a working point on a head capacity curve of pumps driven by the other motors is changed from a normal flow rate point in steady operation to a lower flow rate point determined depending on the pressure loss increased by the pressure loss addition unit.
