摘要： A method of operating a hydraulic or a pneumatic control device of a semi-automatic transmission. The control device has actuator devices with actuating cylinders. Pressure chambers of the actuating cylinders can each be connected, via a control valve, with a pressure line that can be selectively connected with a main pressure line, or blocked, via redundant and parallel positioned main switching valves. The control device has at least one sensor and at least one measured signal is captured by the at least one sensor, depending on the actuation of the main switching valves. The at least one measured signal or each captured measured signal is compared to a stored nominal signal for the respective actuation of the main switching valves and, if a deviation is determined between the measured signal and the respective nominal signal, a defect of at least one of the main switching valves is concluded.

摘要： A hydraulic circuit for actuating an electromagnetic proportional pressure reducing valve by a command current outputted from a controller based on an operation amount of a remote control valve, and by a secondary pressure of the pressure reducing valve, actuating a common bleed-off valve which is a hydraulic pilot type spool valve is provided. In the controller, as a correction processing for correcting characteristics of a proportional valve command value which is a current value given to the pressure reducing valve and the opening area of the spool valve, at an inflection point at which the degree of change of a pump pressure increases, an actual proportional valve command value at a time of obtaining the pump pressure is compared to a theoretical proportional valve command value of a case of no tolerance, and a correction to compensate for a difference between the both command values is performed.

摘要： A safety circuit for media-operated consumers, such as steam turbines or gas turbines, includes at least one first solenoid valve (1.1) which acts on a fluid circuit. An actuating device (9) can be connected to the fluid circuit, and acts at the same time on the operating behavior of the consumer. At least one other solenoid valve (1.2, 1.3) is connected at least to one of the other solenoid valves (1.1) such that only with simultaneous triggering of at least two solenoid valves (1.1, 1.2, 1.3) does at least one control valve (2.1), connected to the fluid circuit (10) act on the actuating device (9). Permanent verifiability can occur with simultaneous implementation of the safety function. A process for operating the safety circuit is also involved.

摘要： A method and system for the controlled application of fluid pressure of a load, such as a large pipe to be pressure t sted utilized small pressure converters which are operated by a common controller at the hydraulic side to fill and pressurize the pipe. One pressure converter is decelerated as it approaches th end of its working stroke while the other pressure converter is accelerated so that the total displacement of the pressurizing fluid remains substantially constant over time.

摘要： An improved pneumatic control system is selectively deactuable and actuable for controlling movement of the armature of a pneumatically-operated device between first and second working positions and includes a timing subsystem that enhances the efficiency of the overall system by stabilizing the control system at a pressure necessary to maintain certain static conditions in the pneumatically-operated device, while still providing for full control air pressure when dynamic operations are required. In addition, such a control system compensates for system leakage in an efficient manner by using full control air pressure only when needed for proper operating functions of the overall system.

摘要： Systems and methods for controlling valve assemblies associated with an actuator in an electro-hydraulic system are disclosed. In one method, a controller monitors hydraulic fluid flow for an actuator to identify one valve assembly connected to the actuator as a meter-in valve and another valve assembly connected to the actuator as a meter-out valve. In one aspect, the valve assembly most recently identified as the meter-in valve is controlled to maintain a pressure setpoint and the valve assembly most recently identified as the meter-out valve is controlled to maintain a hydraulic fluid flow rate. The method can also include determining whether the actuator is in a passive state or an overrunning state and controlling the valve most recently identified as the meter-in valve to maintain a first pressure setpoint when the actuator is in a passive state and to maintain a second pressure setpoint when the actuator is in an overrunning state.

摘要： This application describes apparatuses, systems, and methods that combines specific configurations of a pneumatic actuation system together with a pressure measurement device to allow for measurement of pressure inside isolated subsystems within the system to thereby provide detection of leaks within the system. In certain exemplary embodiments, the apparatus comprises a directional control valve that employs at least one port connectivity configuration that creates at least one isolated fluid subsystem within the overall system. When the valve is in this isolated subsystem configuration, a given mass of fluid (i.e., compressed gas) can neither enter nor leave the subsystem. The leak detection method consists of momentarily placing the valve in this isolated subsystem configuration when switching between standard configurations, and measuring pressure with at least one pressure sensor in the isolated fluid subsystem while in this configuration, where loss of pressure in this configuration indicates existence of a leak.

摘要： Methods and apparatus of assessing a test of a solenoid valve via a positioner are disclosed. An example apparatus includes a solenoid valve to enable an actuator to close an emergency valve and a valve positioner fluidly and communicatively coupled to the solenoid valve. The valve positioner is to instruct the solenoid valve to transition the solenoid valve from a first state to a second state. The valve positioner is to monitor a pressure change of a pressure chamber of the actuator in fluid communication with the solenoid valve relative to an initial pressure for a monitoring duration. The valve positioner is to identify a maximum pressure change during the monitoring duration and determine a ready state of the solenoid valve when the maximum pressure change is greater than a minimum trip value and the pressure change at a monitoring end time is less than a maximum reset value.
