Normalization and monitoring of vibration of process equipmentof pulp-and-paper manufactures
GOST 26493-85 regulates parameters of vibration of equipment of pulp-and-paper manufactures. However this standard is obsolete, does not take into account modern designs of the process equipment and requirement of new state and international standards. In article attempt of normalization and monitoring of vibration of the process equipment is made in view of modern requirements. It is established two criteria of an estimation of vibrating condition of equipment. The first criterion normalizes average quadratic value of amplitude of vibration in octave strips of frequencies, on second - trend of amplitude of vibration on the general level. As an example normalization and monitoring of vibration of mills is considered. Necessity of division to constructive attribute on two groups is revealed. Numerical borders of zones and trend of vibration of mills are determined. The vibrating condition is estimated by four criteria: well; satisfactory; improvement is necessary and is inadmissible. Then it is made decision on possible restriction of the form of functioning of the equipment (the prevention or stop). Introduction of norms and monitoring of vibration of the equipment will speed up transition to repairs on a technical condition. Methods of normalization and monitoring of vibration of the process equipment can be applied in other industries.
