The screw loosening of the shell of the stone crusher is not recommended to be welded directly:
As for the service life of the relevant parts of the machine in the process of use, it has a great relationship with the professional level of your maintenance master. Today, I will discuss with you a very simple topic, that is, in the maintenance process, how to deal with the phenomenon of screw loosening on the shell of the stone crusher?
The phenomenon of screw loosening on the shell of the stone crusher is a more common problem, and how to deal with it properly is necessary. In the real production process, the phenomenon of screw loosening often appears on the newly installed machinery and equipment. Because before the machine leaves the factory, the production workers only tighten it with relevant tools in the workshop, without the actual production environment test, the appearance of individual screw loosening signs is a normal phenomenon.
After the maintenance master finds that the screws are loose on the machine housing, most of them will be manually tightened with the board for the first time. If the screw is found to be loose, many times in order to save time, people will directly die with electric solder joints. But it is not right to do so, Shandong Sanxiang Heavy Industry Co., Ltd. has been telling customers in the stone crusher product maintenance encountered similar situations, it is best not to take the above approach. Because the screws after the death of the solder joint have no cushioning effect, the subsequent loosening signs will be very troublesome to deal with, and the screws with the death of the solder joint are generally very fragile. In the actual operation of the stone crusher, the vibration force generated by the impact of the material is very large, it is very easy to crack the welding, and the consequence is more than worth the loss.
In fact, Shandong Sanxiang Heavy Industry Co., Ltd. shipped the relevant screws used on the shell of the stone crusher, although they are purchased from outside the company, but their quality is strictly tested, the phenomenon of loosening has nothing to do with its quality. In the actual production process, the problem of screw loosening will still occur, mainly the fit problem of screw and nut. After the actual production test, if loose, the first tightening; Re-tightening occurs no more than three times before and after, and the screw will no longer show signs of loosening. Therefore, maintenance workers do not want to save trouble, and they generally understand this truth, just look at the professional level of personal maintenance teachers is not in place.
In short, Shandong Sanxiang Heavy Industry Co., Ltd. in the treatment of stone crusher shell screws loose, the treatment advice is not to use electric welding directly welded dead, it is recommended to tighten, before and after not more than three times, the screw will be permanently fixed. For the relevant details of the daily maintenance of the crusher series of products, Shandong Sanxiang Heavy Machinery has a lot of experience, and then slowly tell you.
