摘要： PROBLEM TO BE SOLVED: To predict the life of a hydraulic pump by detecting the sign of pump rupture before the hydraulic pump is ruptured.
SOLUTION: The delivery pressure 122 of the hydraulic pump, an oil temperature 126, and drain filter pressure difference 120 are detected, a relation 128 between the filter differential pressure and the delivery pressure is obtained, and based on the relation, a typical filter pressure difference 130 under a specified typical delivery pressure is calculated. By correcting the typical differential pressure value 130 by an oil temperature-pressure differential correlation function, a corrected pressure difference from which variable components 132 resulting from the oil temperature 126 are removed can be obtained. The long term trend and the short term trend of the increase of the corrected pressure difference with time are calculated, and the sign of the pump rupture are detected and the life of the pump is predicted by using the degree of separation of the long term trend from the short term trend.

摘要： PROBLEM TO BE SOLVED: To reduce energy loss, and to improve responsiveness of a steering control system.
SOLUTION: When a steering operating element is quickly operated, opening area of a steering flow control valve 4 is quickly increased to quickly reduce a pressure difference (Pp'-PL) between in front and rear of the steering flow control valve 4. When the pressure difference (Pp'-PL) between in front and rear of the steering flow control valve 4 is quickly reduced, a flow control valve 6 is energized by spring force of a spring 6f to quickly move toward a valve position 6b in order to increase the pressure difference (Pp'-PL) in front and rear to make it coincide with a set pressure. Pressure oil at a flow rate α to spare and flowing in a discharging oil passage 7 till then is quickly supplied from the flow control valve 6 to a steering hydraulic cylinder 5 through the steering flow control valve 4.

摘要： A hydraulic control arrangement for operating a winch with an adjustable hydraulic motor in the easing, hoisting and mooring modes. The arrangement comprises a pilot controller with a control lever which can be actuated as desired and can be deflected from a neutral position in opposite directions over a specific easing angle range and over a specific hoisting angle range. Previously, for the mooring mode, the control lever was blocked at a desired point in the hoisting angle range. The control lever, as viewed from the neutral position, can be deflected over a mooring angle range on the other side of the hoisting angle range, with increasing deflection of the control lever in the mooring angle range, the hydraulic motor being adjusted in the direction of a greater absorption volume and therefore in the direction of a greater torque and increased tension on the hawser. This contradicts the usual concept that as the deflection of a control lever increases, that is as the pivoting angle increases, the variable controlled by it also increases.
