Intelligent apparatus for monitoring rotating device

Abstract

The invention provides an intelligent apparatus for monitoring a rotating device. A vibration signal of a rotating mechanical shaft is detected by a first laser displacement sensor, a second laser displacement sensor, a third laser displacement sensor and a fourth laser displacement sensor, and image information at a connecting site of the rotating mechanical shaft and a bearing is collected by using an image collection apparatus so as to judge whether looseness occurs between the rotating mechanical shaft and the bearing, thereby improving the detection accuracy and avoiding misjudgment, an image processing apparatus respectively performs image smoothing processing on the collected image to extract the image information of the image collection apparatus efficiently and quickly, so that the recognition accuracy of the image information at the connecting site of the rotating mechanical shaft and the bearing can be improved, and the occurrence of misjudgment is effectively reduced.

Large-scale, high-speed, and complex are the development directions of rotating machinery. Most of the rotating machinery is power equipment, which is in high-speed operation for a long time. It is very important to ensure the normal operation of this type of equipment. Due to various factors, such as temperature, humidity, friction, etc. Different degrees of impact on rotating machinery, resulting in various failures and affecting the function of the machine

[0003] The main shaft is an important rotating part of the rotating machine. With the operation of the machine, the main shaft will vibrate. When the vibration is detected, it is a reliable means of detecting the operating state of the rotating machine. The vibration signal of the main shaft contains information for judging various operating states. When the vibration of the main shaft is too large, it is easy to cause the gap between the main shaft and the bearing to become larger, resulting in loosening

At present, for the detection device of the vibration signal of the rotating machinery, only the vibration sensor is used to collect the vibration signal, and the vibration signal cannot be accurately obtained, and thus it is impossible to judge whether there is looseness between the main shaft and the bearing.
