Description

Technical Field

[0002] During the liquid food filling process, if a component fails, it is very likely to paralyze the entire production line, resulting in contamination and waste of raw materials. Currently, manual periodic maintenance is usually used to monitor the status of filling production lines. However, this method has poor real-time performance and low reliability. It is unable to detect component failures in time and predict the occurrence of failures in advance. This is especially true for the power components of the filling production line, namely motors, reducers and liquid pumps. If failures such as liquid pump leakage occur, it will cause huge losses to the manufacturer. The occurrence of these failures often has traces. The operating status before the failure will be different from the normal operating status. These differences are often difficult to detect with the naked eye. Therefore, a monitoring device is needed to predict the occurrence of power component failures in advance. Utility Model Content
