The repair is to restore the mining machinery and technical performance, troubleshooting, eliminate hidden dangers, and effective means to extend the mechanical life of the. The existence of technical problems, resulting in high quality of mining machinery maintenance equipment recoverability, the consumers will suffer, or even a serious accident.Blind replacement parts, the blindly for parts repair phenomena exist to varying degrees. The mining machinery failure is relatively difficult to judge and exclude some maintenance personnel, some traditional pieces of test methods, regardless of the large small pieces, as long as that could lead to the failure of parts, a replacement test, the result is not only the fault did not exclude, and replacement parts should not arbitrarily replace and increase the customer's expense. Maintenance, should be based on the failure phenomenon a careful analysis to determine cause of the malfunction and location, able to repair the parts to be taken to repair the to resume technical performance, put an end to the practice of blindly replacement parts.
Does not check the quality of the new parts, after assembly failure of the more common problems. Replacement parts, some maintenance personnel without technical inspection of new accessories brought directly installed on mining machinery, such an approach is unscientific. The sale of spare parts on the market quality is good and bad, uneven, some counterfeit parts fish, there are a number of accessories due to inventory a long time, performance change, if not been tested, often caused by the failure occurred after assembly. Therefore, replacement parts must carry out the necessary checks test to detect the appearance and performance testing to ensure trouble-free new accessories to eliminate its cause unnecessary trouble.
Not pay attention to accessories models, accessories alternative or misuse of the phenomenon is more common. Accessories alternative or misuse of the phenomenon is still more prevalent in the maintenance of mining machinery, some accessories emergency alternative is feasible, but long-term use is detrimental to the mechanical safety and technical performance. Some maintenance staff of the mechanical structure, the principle of less well understood, a lot of spare parts model does not match, and concluded that they can hold on the line, do not consider the possibility to play the technical performance of the machine. Maintenance of mining machinery, you should try to use the original type of accessories, not use other models accessories alternative, not to misuse.
