我厂所属矿山1台PYD2100短头圆锥破碎机,1978年和1987年两次因锥头松动没及时发现,衬板松脱撞击,造成轴头M200的螺纹严重磨损。如不及时修复会造成很大损失,按常规应送大型机械厂补焊加工,要花费大量运费和加工费,而且时间还长。经研究,我们用现有的ZD—300型动力头加以改造,修好了这个12t重的大件(第一次用5天,第二次用3天),既保证了质量,又减少了停产时间,节约了大笔开支。具体方法是: 1.将拆下的锥体平放在地板上,找正轴线,两端用支架固定好;
My factory belongs to a mine PYD2100 short head cone crusher, 1978 and 1987 twice because of the loose cone was not found in time, the liner release impact, resulting in serious head shaft M200 wear and tear. If not repaired in time will cause great losses, according to the conventional large-scale mechanical factory should be repaired welding, to spend a lot of freight and processing fees, but also for a long time. After the study, we use the existing ZD-300-type power head to be modified, repaired the 12t heavy bullet (the first five days, the second with three days), both to ensure the quality and reduce the shutdown Time, save a lot of expenses. The specific method is: 1. Remove the cone flat on the floor, find the positive axis, both ends of the bracket fixed;
