Problems solved by technology

[0004] However, if the sensor probe is not installed properly, it is very easy to cause the displacement to exceed the alarm setting value and cannot automatically trigger the light alarm signal and the relay output point control signal output, thus failing to achieve the monitoring and alarm functions.

Embodiment Construction

[0015] The invention is mainly used for sensor positioning and installation, and provides a sensor installation method, which includes a sensor probe, a probe bracket, an extension cable, and a front-end device. The specific installation steps are as follows:

[0016] Step 1. Install the sensor probe to the probe bracket and reinforce it. The position of the sensor probe should be selected within the range of 3 times the diameter of the probe without other metal substances. At the same time, the probe bracket should be rigid enough to prevent the probe bracket from vibrating and deforming;

[0017] Step 2. Connect the sensor probe and the preamplifier with an extension cable. After the connection is completed, the protective sleeve between the probe and the extension cable connector should be connected well, and the cable should be fixed. The extension cable cannot be arbitrarily lengthened or shortened, and it cannot be cancelled. It will cause the characteristics of the senso...

Abstract

The invention discloses a mounting method of a sensor. The mounting method is used for mounting a sensor probe in vibration monitoring of mechanical equipment. The mounting method has the beneficial effects that the adopted the non-contact type sensor is not affected by media such as oil and steam in detection, when the displacement exceeds an alarm set value, and a light alarm signal and a relaycontact control signal can be automatically output, thereby achieving the functions of monitoring and alarm.

Description

technical field [0001] The invention relates to the field of vibration monitoring of mechanical equipment, and an installation method of a sensor probe in the vibration monitoring of mechanical equipment. Background technique [0002] Vibration monitoring is an indispensable detection and protection device for various large-scale rotating machinery (such as steam turbines, fans, compressors, motors, pumps, and gearboxes). It cooperates with the vibration velocity sensor to continuously monitor and measure the absolute vibration of the bearing shell of the rotating machinery. There is a current output proportional to the measured value, which can be directly connected with DCS, PLC systems, and paperless recorders. When the vibration amplitude exceeds the limit, it can automatically provide alarm relay switch contact output. [0003] The existing vibration monitoring equipment has the characteristics of high reliability, stable performance, large linear range, wide frequenc...
