中速磨煤机振动影响因素的研究
Research on influence factors of vibration of medium speed coalpulverizers
摘要
Abstract
The long-term vibration of ZGM133G-I type medium speed coal pulverizers in a power plant causes weld fatigue fracture of the powder delivery pipeline,which results in coal powder leakage,polluting the environment and seriously affecting the operation of the unit.Based on the mechanical vibration analysis and field test of medium-speed coal pulverizers,this paper studies the influence of operating parameters such as loading force,speed of separator and output of coal pulverizers on the vibration of coal pulverizers.The results show that,the vibration of medium-speed coal pulverizers is mainly caused by the mechanical equipment itself and the setting of operating parameters.The size and separator type of coal pulverizers are not the inevitable factors that cause the vibration of coal pulverizers,but the wear and damage of mechanical structure will cause the vibration of coal pulverizers.In order to reduce the vibration of medium-speed coal pulverizers,it is necessary to comprehensively consider the output of coal pulverizers and the fineness of coal powder according to the test results,and reasonably control the loading force,separator speed and output.关键词
