Portable shaft vibration gauge

Abstract

The invention discloses a portable shaft vibration gauge which is shown as the figure of the abstract. The portable shaft vibration gauge comprises two parts of a magnetic sensor (3) and a handheld shaft vibration signal processor (4), wherein the main body of the magnetic sensor (3) is an L-shaped metal bracket; the shaft vibration sensor is mounted on one arm; and a magnetic base is mounted on the other arm. The distance between a probe of the shaft vibration sensor and the surface of a measured shaft can be adjusted according to the actual condition; the magnetic base can be absorbed on a still iron metal member close to a rotary shaft; the magnetic sensor transmits the measured vibration signals to the handheld shaft vibration signal processor through a lead; and the final shaft vibration measuring result is displayed through analysis processing.

Description

technical field [0001] The invention is a portable non-contact vibration measuring instrument for measuring the vibration of a rotating shaft, which belongs to the technical field of vibration analysis and testing. Background technique [0002] With the development of large-scale units, neither the shaft vibration nor the bearing vibration alone can fully reflect the vibration characteristics of the unit. The combined analysis of the shaft vibration and the bearing vibration can often dig out much more in-depth information than the individual bearing vibration or bearing vibration data. information. At present, the portable monitoring methods for the vibration of rotating machinery mainly focus on the monitoring of the tile vibration, and the portable monitoring of the shaft vibration signal is still blank. Vibration monitoring for rotating shafts is currently mainly carried out by arranging fixed vibration sensors close to the rotating shaft in the design stage of the unit...

AI Technical Summary

Problems solved by technology

At present, the portable monitoring methods for the vibration of rotating machinery mainly focus on the monitoring of the tile vibration, and the portable monitoring of the shaft vibration signal is still blank.

Vibration monitoring for rotating shafts is currently mainly carried out by arranging fixed vibration sensors close to the rotating shaft in the design stage of the unit. There is no vibration measurement for rotating shafts where no measuring points are arranged on site or where it is inconvenient to fixedly arrange vibration sensors. Effective means are not conducive to comprehensive, real-time and convenient monitoring of the shaft vibration of rotating machinery in operation. Only relying on a single tile vibration signal will affect the diagnosis result and even delay the processing time

Especially for some auxiliary equipment with no vibration measuring points or relatively few measuring points, this problem is particularly prominent when there is a vibration fault that needs to be dealt with
