Is not all the faults, of course, this knowledge is the common faults and solutions in the DTH Bit of the engineering down-the-hole drilling rig. Just for your reference. Let's follow the editor to learn more about it.
DTH Bit of the down-the-hole drilling rig in the project will not only affect the cost but also delay the construction period if any failure occurs. However, the failure of the DTH Bit of the down-the-hole drilling rig is unavoidable and can only try to reduce the probability of failure. Regarding some simple and non-professional faults, you can fix them yourself if you can fix them yourself. To reach such a specification, then you must understand some of the rare failures and repair methods of DTH Bit. Of course, if the problem is too professional, it is recommended not to do it yourself.
The rare failures of DTH Bit of engineering down-the-hole drilling rig usually include stuck drill, drill rod orbit failure, inability to evacuate chips, and weakness of DTH Bit of down-the-hole drilling rig. The solution is as follows.
1. stuck drill
Its solution is also very costly. That is cleanup. Some gravels, steel wires, casings, small parts, etc. accidentally enter the well or go deep into the drilling tool during work, which can cause sticking.
2. Drill rod or drill bit failure
It should be due to operation and common running reasons that the drill rod or the failure of the drill bit may cause the DTH Bit of the engineering down-the-hole drilling rig to fail to operate normally. The better solution is to replace it.
3. Unable to remove chips
So I love to form chip evacuation blockage. The solution is to dredge. Some types of DTH Bit in engineering DTH bit have poor chip removal effect. But the better prevention effect is to increase the air volume.
4. Down-the-hole drill DTH Bit is weak
If it is pneumatic, it may be due to the lack of air pressure. There are many factors that cause the weakness of the DTH Bit of the down-the-hole drill. There are many reasons for the lack of air pressure, which need to be corrected after searching, and the hydraulic pressure is mostly due to lack of oil or oil pump problems. Check and correct it.
