摘要
常规的螺栓拆卸方法常常造成过滤器的紧固螺母损坏、螺纹拉伤。采用螺栓拉伸法进行螺栓的拆卸和安装,可以非常有效地解决问题。文章对螺栓拉伸法在聚酯熔体过滤器螺栓装拆作业中的应用进行了介绍。
Using conventional methods to dismantle the bohs of polymer filter often cause the fastened and nuts damaged seriously. But, when forcing the bolts in pre-stretched state, the dismantling and installation become very smoothly and effectively.
