(Summary description)Fans are commonly used equipment in chemical companies. In some chemical companies, there are as many as hundreds of various types of fans, and there are dozens of them. The vibration of the fan caused by the imbalance of the impeller occurs from time to time during the operation of the equipment, so the wind power balance detection will affect the continuous and stable operation of the production system to a large extent.   Due to the uneven material of the fan rotor, manufacturing, processing and installation errors, changes in operating conditions, rotor fouling, wear, and even parts flying off, it is inevitable that the eccentricity of the mass makes it deviate from the axis of rotation of the rotor, causing the rotor The imbalance caused vibration. Now briefly explain the three situations of fan unbalance, static unbalance: The resultant force produced by the eccentric masses on the rotor is not equal to zero, that is, this unbalance force can be determined in a static state, so it is called static unbalance. Dynamic unbalance: The eccentric masses on the rotor synthesize two unbalanced forces of equal magnitude and opposite directions but not on the same straight line. Although the rotor is balanced when it is stationary, it will produce an unbalanced couple when rotating, namely ∑ M ≠0, this kind of imbalance can only be determined under dynamic conditions, so it is called dynamic imbalance. Mixed imbalance: A rotor has both static imbalance and dynamic imbalance. Mixed imbalance is a common state of rotor imbalance, especially rotors with a relatively large length and diameter, which often produce mixed imbalance. Over the years, we have carried out dynamic balance tests on fans, and have accumulated a wealth of information and data. Through careful sorting, analysis, and research of these materials and data, we have explored and summarized the law of aggravation of the fan and motor rotor, that is, measured before the fan is shut down. By obtaining the original unbalanced vibration parameters of each bearing bush, the phase and size of the unbalanced mass of the fan rotor can be found immediately, so that the balancing work of the fan rotor can be completed as long as it is turned on and off once.
