Abstract

The invention relates to a portable eddy-current transducer state checking device and checking method. In the prior art, an eddy-current transducer aiming at the shaft vibration measurement has high installation requirements and has the very definite requirement on the installation distance, so that certain difficulty exists in the detection on the monitoring abnormality of a shaft vibration probein the operation process. The portable eddy-current transducer state checking device disclosed by the invention comprises a snake-shaped magnetic support frame, a magnetic rail, an electric non-return controller, a rail screw bolt, a transducer support frame and an eddy-current transducer, wherein the magnetic rail is arranged on the snake-shaped magnetic support frame; the electric on-return controller is arranged on the transducer support frame; the transducer support frame is connected with the magnetic rail through the rail screw bolt; the eddy-current transducer is arranged on the sensorsupport frame. The portable eddy-current transducer state checking device and checking method can be applicable to the checking of the eddy-current transducers of large-scale rotation machinery of different types; the use is convenient; the state checking of the field eddy-current transducer can be realized; the on-line addition function of the eddy-current transducer by the equipment is realized.

Description

technical field

[0001] The invention relates to a portable eddy current sensor state check device and a check method, in particular to realize the check of the state of an online eddy current vibration sensor when the equipment is running without stopping. Background technique

[0002] In order to ensure the safe and stable operation of large rotating machinery, vibration monitoring is usually carried out on equipment. Vibration monitoring is mainly divided into two parts: shaft vibration monitoring and bearing seat vibration monitoring. Usually, the vibration monitoring of bearing seats is realized through speed sensors, while the shaft vibration monitoring This is achieved with eddy current probe sensors.

[0003] In the daily operation process, sometimes there will be sudden changes in the monitoring vibration data or abnormal data, but at the same time, no abnormalities are found in the analysis and comparison of other monitoring parameters. Therefore, the accuracy of v...
