In chemical plants, 50% to 70% of the damage to the transmission equipment is caused by the out-of-alignment of the coupling. The direct loss is the cost of replacing the spare parts, and the indirect loss is the unplanned shutdown which causes greater downtime profit loss. , How to detect the alignment error of the coupling early and take timely measures to avoid the expansion of losses is a serious concern in chemical plants. Vibration analysis is one of the techniques to predict the misalignment of the coupling. It can judge the state of the equipment. The gradual change trend.

　　But when judging whether a piece of equipment is in a misaligned state, it is necessary to have a lot of data and examples in the past for reference, and also to distinguish whether it is a bearing, lubricating oil, coupling, or a fixed connection, so there are certain limitations.Infrared photography technology can distinguish overheated parts such as bearings, motor housings, couplings, etc. when the equipment is in poor condition, and determine the alignment error of the coupling, combined with other prediction technologies such as vibration analysis , Its effect will be better.
