Abstract
A monitoring sensor for a state of a blade of a rotating machine includes a sensor for monitoring a state of the blade of the rotating machine, a first section configured to be fixed to a casing of the rotating machine, and a second section holding the sensor and supported by the first section so as to be able to adjust a position of the sensor in an axial direction of the casing.
Claims10
A monitoring sensor for a state of a blade of a rotating machine, comprising:
- a sensor for monitoring a state of the blade of the rotating machine;
- a first section configured to be fixed to a casing of the rotating machine;
- and
- a second section holding the sensor and supported by the first section so as to be able to adjust the sensor in an axial direction of the casing such that measurement of the sensor is performed in a predetermined orientation with respect to the blade.
A position adjustment method for a sensor for monitoring a state of a blade of a rotating machine, with a first section being fixed to a casing of the rotating machine, and a second section holding the sensor and being supported by the first section, the method comprising:
- a position adjustment step of changing a positional relationship between the first section and the second section to adjust a position of the sensor in an axial direction of the casing.
A rotating machine comprising:
- a rotational shaft provided with a plurality of blades;
- a casing accommodating the rotational shaft;
- a monitoring sensor for monitoring a state of the plurality of blades, the monitoring sensor being inserted in a through hole of the casing disposed along a radial direction of the casing, a tip of the monitoring sensor protruding to an inner side of the casing;
- and
- a sensor protective part attached on an inner peripheral surface of the casing at a position upstream of the through hole with respect to a rotation direction of the blades.
