Actuator predictive system |
| 摘要 |
An actuator system includes a piston-cylinder arrangement including a piston that is movable with respect to a cylinder. A first flow path is in fluid communication with the piston-cylinder arrangement and a second flow path is in fluid communication with the piston-cylinder arrangement. A control system is operable to fluidly connect the first flow path to a source of high-pressure fluid and to connect the second flow path to a drain to move the piston in a first direction. A pressure sensor is fluidly connected to the first flow path and is operable to measure sufficient pressure data during the movement of the piston to generate a pressure versus time curve. The control system is operable to compare the generated pressure versus time curve to a known standard pressure versus time curve stored in the control system to determine the condition of the piston-cylinder arrangement. |

1. An actuator system comprising:
a piston-cylinder arrangement including a piston that is movable with respect to a cylinder; a first flow path in fluid communication with the piston-cylinder arrangement; a second flow path in fluid communication with the piston-cylinder arrangement; a control system operable to fluidly connect the first flow path to a source of high-pressure fluid and to connect the second flow path to a drain to move the piston in a first direction; a pressure sensor fluidly connected to the first flow path and operable to measure sufficient pressure data during the movement of the piston to generate a pressure versus time curve, the control system operable to compare the generated pressure versus time curve to a known standard pressure versus time curve stored in the control system to determine the condition of the piston-cylinder arrangement; wherein the control system includes a microprocessor and a memory device, and wherein the known standard pressure versus time curve is generated for the piston-cylinder arrangement during one or more initial operating cycles and is stored in the memory device. |
