Abstract
A leakage-cause discrimination system discriminates a cause of leakage of working fluid through an annular gap between a piston rod of a fluid pressure cylinder and a cylinder head through which the piston rod is inserted. The leakage-cause discrimination system includes a measurement unit provided on the fluid pressure cylinder, the measurement unit being configured to measure a state quantity of the working fluid leaking through the annular gap and a controller configured to acquire a measurement result from the measurement Unit. The controller discriminates the cause of leakage based on a change in the state quantity of the working fluid measured by the measurement unit.
Claims7
A leakage-cause discrimination system for discriminating a cause of leakage of working fluid through a gap between a piston rod of a fluid pressure cylinder and a cylinder head through which the piston rod is inserted, the leakage-cause discrimination system comprising:
- a measurement unit provided on the fluid pressure cylinder, the measurement unit being configured to measure a state quantity of the working fluid leaking through the gap;
- and
- a controller configured to acquire a measurement result from the measurement unit, wherein
- the controller discriminates the cause of leakage based on a change in the state quantity of the working fluid measured by the measurement unit.
A leakage-cause discrimination method for discriminating a cause of leakage of working fluid through a gap between a piston rod of a fluid pressure cylinder and a cylinder head through which the piston rod is inserted, the leakage-cause discrimination method comprising:
- a step of measuring a state quantity of the working fluid leaking through the gap, on the fluid pressure cylinder;
- and
- a step of discriminating the cause of leakage based on a change in the state quantity of the working fluid measured.
