The Preservation Of DTH Drilling Tools

DTH drilling tools storage during downtime is a neglected problem. The preservation of equipment and drill tools is very important for the use of equipment and drilling tools.

The preservation of the drill pipe

1. Blowing the air, clean the water inside the drill pipe, and open the solder tail lubrication device. In principle, it is best to see the tail lubricant at the bottom of the drill pipe.

2. The outside of the drill pipe, including the threaded portion, and the main body of the drill pipe, must be wiped clean. At the same time, the male and female joint parts should be covered with the rubber cover to prevent the entry of pollutants. The rubber cover is small and cheap, which can greatly reduce the impactor failure caused by pollution.

Short-term preservation of impactors

1. Blowing air to remove moisture from the impactor. 

2. Fill 1 liter of tail oil from the upper joint.

3. Opening the air and blow for about 10 seconds. This will fully lubricate the internal parts of the impactor. 

4. It is like the drill pipe, the upper and lower joints are respectively covered with rubber caps.

5. Placing the impactor horizontally in a dry environment.
