摘要
执行机构在使用中会出现各种故障,其中力矩故障最频繁。文中通过对阀门不同部位摩擦力的变化及阀门限位的分析,找出了产生力矩故障的原因。针对不同的原因结合成品油管道的特点,采取力矩保护参数修改、限位调整、阀杆及填料润滑保养、阀门排渣润滑、定期加换油等措施,通过在成品油管道中的实践应用,取得了较好的效果。
Actuators in use can appear all kinds of fault, the moment of failure is the most frequent. In this paper, through the analysis of change of the different parts friction force of valve and valve limit, this paper analyzed the reasons of the frequent torque failure of the torque. According to the characteristics of the product oil pipeline due to different reasons, measures are taken such as moment protection parameter modification, limit adjustment, stem and packing lubrication maintenance, valve sludging, change and add oil on a regular basis. Through practical application in product oil pipeline, good results are achieved.
