Abstract

The invention discloses a device for on-line monitoring and evaluating state of an air blower. The device comprises a data collection and operation module, a master controller module and a communication interface module, wherein the data collection and operation module is used for collecting parameter information of vibration of the air blower, temperature, voltage, electrical current, pressure, and the like; vibration signals of the air flow are decomposed by adopting a method of multiwavelet; early failure characteristic signals are extracted; performance evaluation is performed by adopting state performance evaluation algorithm based on a cloud model; the collected signals of the temperature, the pressure, and the like are distinguished and displayed by the master controller; and the device is equipped with a plurality of communication interfaces, so that data exchange between information and factory control net and manufacturing execution system can be realized. Through adoption of the device, performance state of the air flow can be evaluated accurately, so that reasonable maintenance for the air flow is realized.

Description

technical field [0001] The invention relates to the field of electromechanical equipment maintenance and fault diagnosis, in particular to an online state monitoring and evaluation device for a fan. Background technique [0002] Fans widely used in process industries such as metallurgy and electric power are one of the large-scale rotary equipment, and their operating conditions are directly related to the safe and economical operation of factories. Therefore, the requirements for the safety and economic performance of fans are becoming more and more stringent. Therefore, the implementation of fan status monitoring and fault diagnosis is of great significance to the improvement of the safety status of the plant equipment system. At present, scholars at home and abroad have conducted in-depth research on the methods and technologies of fan fault diagnosis, and proposed methods such as signal processing fault diagnosis and data-driven fault diagnosis. But there are few studie...
