What should be paid attention to when using DTH drill bit?

In the overall structure of the digging machine to change the hydraulic down-the-hole drilling rig, the drill bit has a significant influence. It can be said that the extremely sharp weapon in the whole drilling rig is not too much, so the protection of the drill bit is very important in use. Also pay more attention when using, the following mining excavation rig manufacturers I will introduce.

1. Select the down-the-hole drill bit according to the condition of the rock formation (strength, abrasion) and the type of drilling machine (high pressure, low air pressure). Different types of alloy teeth and cloth teeth are suitable for drilling in different rock formations. Choosing the right DTH bit is a prerequisite for optimal drilling.


2. When installing the down-the-hole drill bit, the drill bit should be gently embedded in the drill bit of the down-hole impactor card, and should not be struck with force to prevent damage to the drill bit or the card sleeve.


3. In the rock drilling step, ensure that the pressure of the downhole drilling rig is sufficient. If the impactor is intermittently operated or the blasthole powder is blocked, the compressed air system of the downhole drilling rig should be inspected to ensure that there is no slag in the hole during the drilling process.


4. If the metal object is found to fall into the hole, it should be immediately sucked out by the magnet or otherwise made out to prevent the drill bit from being destroyed.


5. When you remove the drill bit, pay attention to the size of the drill hole that has been drilled. If the diameter of the drill bit is excessively damaged, but the blasthole is not drilled, the new drill bit cannot be replaced to prevent the drill. It can be used with old drill bits that have been used and have the same diameter.


The above is the precautions for the use of the drill bit in the hydraulic submersible drilling rig. Only when the weapon in the hand of the rig is well protected, the failure rate in use will decrease, the work efficiency will increase, and the economic benefit will also increase.
