For the breaking hammer drill rod, as long as it is the hammer of the machine are not unfamiliar, the parts are expendable, it can not be repaired after serious wear and tear and it only will be new, and as the “forward general” of the breaking hammer, the price of a drill rod is not cheap, for at least one thousand yuan, if broken then can be forged and updated.
The fault phenomenon is not complicated, and the machine can be found easily, basically, the oil leakage is serious at the drill rod and the front end cover.
Inspection process: The disassembly of the drill rod was found to be damaged, and the further disassembly of the crusher assembly found that the main seal of the piston head contained a residual iron pin when the drill rod was damaged, resulting in abnormal wear of the lip shaped drill rod.
Inspection results:
No.1: the maintenance personnel and the operator after communication found that the driver into the line is not long, the use of the hammer is not standardized, combined with the inspection process can determine the drill rod damage is caused by the empty operation.
No.2. Another important reason is that the abnormal wear of the drill rod is caused by the operator’s placement of the drill rod and the broken material when operating, and the operation is caused by such a long time.
Processing mode:
No.3 for the damage of the excavator in the article, the main piston seal needs to be replaced, in view of the wear of the drill rod is not serious, so the damaged drill rod can continue to be used.
No.4 here another mention, if the wear of the drill rod has been very serious, the efficiency of the crushing operation has been greatly reduced, can only be replaced!
In SUMMARY:
In the final analysis, 90% of the above fault problem can be attributed to the wrong operation of daily crushing operations, such as not empty, vertical with the crushing, pay extra attention to the water, mud, sand and other environments, and importantly, the daily maintenance of the crusher can not be slack.
