Disassembly DTH Button Bits
DTH Button Bits disassembly can be one of the most dangerous and cumbersome tasks in drilling operations. However, if you use the appropriate. With the right tools and the right approach, it may only take a few minutes. Listed below are the most effective ways to help you quickly, securely safe, injury-mitigating impactor components and assemblies to disassemble DTH Button Bits.
-
Use sharp chain pliers. Worn, slippery chain jaws increase the clamping force, and it is easy for the chain jaws to damage the outer wall of the DTH Drill Hammer. The outer wall of many Atlas Copco DTH Hammer is very hard, so sharp chain pliers are required to secure it.
-
Tighten the outer sleeve at the proper position. Tightening the outside of the thread makes loosening of the thread more difficult. Example: When the chain pliers tighten the outer casing with inward force, if the threads are in it, the threads are also compressed. This will only increase the torque required to remove the threads. Also, do not tighten the outer sleeve where it is not supported by the piston or guided case inside the outer sleeve. Tightening without support will distort the outer casing.
-
It is necessary to ensure that the DTH Button Bits is properly matched with the DTH Button Bits removal frame. If the match is not suitable, it may cause the DTH Button Bits to slide from the removal frame.
-
Do not use welding or hammering on the outer casing to remove it. All outer casings are hardened by quenching, which can prolong its service life. Hardened surfaces may be cracked by welding or the impact of a hand hammer. If the front top sub or rear top sub is difficult to disassemble, it may be possible to use a copper rod or a copper hammer to tap continuously on the threaded connection part of the outer casing. At this time, applying torque may disassemble the connection.
