摘要： An alarm management system includes an alarm management system server (“alarm server”), one or more data sources, and one or more system users (and associated user devices), all of which can be communicably connected through a communications network. The system can be configured by defining the data sources and users, defining attributes, assigning and associating attribute values with the data sources and users, and defining alarm conditions in terms of attribute values and measurements. The data sources generate measurement data which is provided to the alarm server, and the alarm server evaluates the data to determine whether the alarm conditions have been met. A data set of data sources matching alarm conditions can be generated and reported to one or more of the users.

摘要： An electrohydraulic system for control of a variable output pump includes a microprocessor-based controller receiving inputs from condition sensors coupled to the pump and command inputs from a remote master controller. The controller supplies outputs to an electrohydraulic valve for metering hydraulic fluid to a pump control port and thereby controlling pump operation in any one of a number of preselected and prestored pump control modes. A hydromechanical valve is connected in parallel with the electrohydraulic valve for controlling pump operation in the event of electrical malfunction or failure. Circuitry connected between the pump condition sensors and the control computer prevents aliasing errors due to mismatch between the computer sampling frequency and pump speed.

摘要： A rotary hydraulic machine which includes a housing having a shaft mounted for rotation within the housing about a shaft axis. A cylinder block is coupled to the shaft for corotation with the shaft within the housing and includes a plurality of cylinders disposed in a circumferential array parallel to and surrounding the shaft axis. A piston is disposed to reciprocate within each of the cylinders and is coupled to a yoke for determining displacement of the pistons within the cylinders. A valve plate is affixed within the housing and includes arcuate slots at a radius from the axis of rotation corresponding to that of the cylinders. The slots respectively connect cylinders to the machine inlet and outlet ports as the cylinders register with the slots. In accordance with a distinguishing feature which characterizes one aspect of the present invention, the valve plate also includes first and second pressure valves respectively mounted on the plate adjacent to leading edges of the arcuate slots (with respect to the direction of cylinder rotation) and responsive to fluid pressure for porting the cylinders to the adjacent slots and thereby, in effect, extending the arcuate dimension of the slots and altering machine timing as a function of fluid pressure.
