摘要： A method for isolating a fault or blocked work port in an electro-hydraulic system is disclosed. In one step, a system pump is set to a first predetermined pressure and a valve assembly is commanded to a center position. In another step, the center position of the valve is recorded. In one step, the valve assembly is opened to place a work port associated with the valve in fluid communication with the pump, after which a first end position of the valve, a first work port pressure, and a first pump supply pressure are recorded. In another step, the valve assembly is opened to place the work port to a tank reservoir, after which a second end position of the valve and a fluid pressure associated with the work port are recorded. The recorded and measured data can then be analyzed to identify the fault condition or blocked work port.

摘要： The invention relates to a system for determining a potential future failure of an actuated valve controlling fluid flow in a line by causing an angular change between two states of a stem of said valve, which comprises: (a) a sensor for, upon receipt a control command at said actuator, continuously sensing the angular position of the stem, and conveying to a monitoring unit a respective angular variation signal; and (b) a monitoring unit which comprises: (bl) a sampling unit for receiving said angular variation signal, and producing a transition vector which comprises periodical samples from said signal; (b2) a local storage for storing nominal transitional values for said actuator- valve pair; and (b3) a local comparator unit for comparing at least a portion of said transitional vector with the corresponding stored nominal transitional values, and if a difference above one or more predefined threshold values is determined, issuing an alert for a potential failure of said actuator.

摘要： A system for measuring the position of a rod element as, for example, a hydraulically or pneumatically operated piston rod. Unlike the prior art, the system according to the present invention employs a measuring principle that does not require preparatory treatment of the rod element as is required in the known solutions. The system employs direct time of flight measurements with the aid of acoustic surface waves that are introduced into the rod element. The instrument is retrofittable on existing cylinders without any modification/reconstruction thereof. An EMAT principle is employed to introduce the surface waves into the measurement in a non-contact manner.

摘要： A method of deactiving an underwater hydraulic device provides a hydraulic device that is capable of being operated under water, the device having a hydraulic cylinder with a pushrod and a piston. The device is lowered below a water surface with a hose reel that is located at the water surface area such as on a marine vessel. The hose reel includes first and second hydraulic hoses that connect to the cylinder on opposing sides of the piston. Fluid flow in the first and second hydraulic hoses is continuously monitored. The ratio of the volume of fluid flowing into the cylinder from one side of the piston to the volume of fluid flowing into the cylinder from the other side of the cylinder is continuously calculated with a computer or controller. The hydraulic device is deactivated if the ratio varies from a preset value. One embodiment includes a plurality of flow meters for measuring fluid flow to and from one or more hydraulicly powered apparatuses. In one embodiment outputs of the flow meters are analyzed to determine if the hydraulic system has a leak, and if a leak is detected, a warning is issued and/or one or more of the connected hydraulically powered apparatuses are shut down, and/or the hydraulic power supply is shut down.
