I believe that many customers and friends will encounter the DTH Bit installed and the air valve opened, and only the exhaust sound of DTH Bit peeing...but there is no impact.
You should stop at this time, take it apart patiently, check the inside of the DTH Bit carefully, and don't perform brutal operations.
That is generally checked from the following aspects:
①Check whether the internal parts of the DTH Hammer are fuzzed, and then use oilstone and sandpaper to smooth the fuzzing position. Of course, after polishing, we need to investigate the cause of the fuzz
Ⅰ. Check whether the lubricating oil meets the requirements for use, and require replacement of high-quality rock drill oil?
Ⅱ. Does the amount of oil supply meet the requirements in the lubricant meter, check and adjust the amount of oil supply?
②Check if there is any ballast inside, remove it and clean it carefully before installing. In this step, many construction sites have limited conditions, but it is also necessary to use potted diesel to clean the DTH Hammer parts, not to be careless.
③Remove the DTH Hammer and check if there is any damage to the parts. Focus on checking the cylinder liner, piston and outer cylinder for cracks. After removal, use oilstone and sandpaper to remove the burrs, replace the damaged parts, and install after cleaning!
