Second, 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, a rubber cover (as shown in the figure below) should be added to the male and female joints to prevent pollutants from entering. Storage and reactivation of impactors For short-term storage, follow these steps: First, blowing to remove the water in the impactor; Condly, filling 1 liter of bit oil from the upper joint part; Third, turn on the air and blow for about 10 seconds, so as to fully lubricate the internal parts of the impactor; Fourthly, like the drill pipe, the upper joint and the lower joint are respectively covered with a rubber cover; Fifth, place the impactor horizontally in a dry environment. Long-term preservation, slightly different First, blowing to remove the water in the impactor; Second, loosen the upper joint and the lower joint, and disassemble the impactor; Third, check and wipe all the internal parts, preferably in a clean room; Fourth, properly lubricate all parts with proper lubricating oil; Fifthly, assemble the impactor and cover the upper and lower joints with a rubber cover; Sixth, place the impactor horizontally in a dry environment. Reactivating the impactor requires the following three step First, disassemble the impactor and inspect all the internal parts. If it is found that the surface of some parts is oxidized, it is necessary to polish the oxidized parts with sandpaper. If the impactor is put into use without testing, it is likely to cause premature failure of the impactor. Second, clean the parts, wipe them clean and lubricate them. Thirdly, the cleaned and lubricated parts are assembled into an impactor, which can be put into use. Read the above article, may be a lot of people think, we usually put casually, do not still use?! Many users will record the wear and tear of drilling tools, such as a hammer used for several months and so on. In today's market depression and fierce competition, the price of rock drilling has been declining. Xiaobian suggests that our majority of down-the-hole drilling rig users can try to work hard on maintenance, such as using and preserving drilling tools according to our suggested methods, carrying out reasonable maintenance and lubrication in strict accordance with the requirements, and trying to see if the life of drilling tools can be longer than before, so as to help you save more money. Machines are more reliable than people. If you are good to machines, machines will be good to you.
