The invention discloses a fan failure analysis method, device, equipment and computer-readable storage medium. The method includes continuously collecting the vibration data and temperature data of the fan bearing of the fan to be tested, and obtaining the effective value of the speed and the impact amount of the vibration data Average value; performing linear fitting on the effective value of the velocity, the average value of the impact amount, and the temperature data to extract the first characteristic information; performing a morphological distribution parameter operation on the effective value of the velocity and the average value of the impact amount to extract the second characteristic information; Perform Fourier transform on the vibration data and temperature data to obtain the corresponding frequency spectrum value to extract the third feature information; according to the combination of the three feature information corresponding to each fan failure type determined in advance, determine the current fan under test Fault type. This application extracts features from three different aspects of the data of the fan to determine the failure of the fan in time, which is conducive to the timely maintenance of the fan and prolongs the maintenance of the fan.
Description
technical field [0001] The present invention relates to the technical field of fan, in particular to a fan failure analysis method, device, equipment and computer-readable storage medium. Background technique [0002] With the continuous development of modern industry, fan equipment has become one of the indispensable mechanical equipment in many factories, and fan equipment is becoming more and more complex and systematic. The property loss caused by fan equipment failure cannot be underestimated. Therefore, it is of great significance to find out the abnormal state of the fan in time and carry out maintenance to ensure the stable operation of the equipment, reduce the cost of maintenance, and prolong the service life of the fan. [0003] However, most of the time, there are only minor faults inside the fan, and there are potential safety hazards at this time. It is really difficult for the staff to judge and find the internal faults of the fan with the naked eye. Content...
