DTH hammer down hole drilling tools rock drilling tools button bit drill dth bit dth hammer Serial NumberFailure ContentCauses of failurePrevention or Solution1It fractures in the taper thread area of the top sub.Drill pipe thread and the top sub thread do not match with each other1. Check if there is burr and flash on the drill pipe thread. File the burr and the flash down. 2. Check if the drill pipe and the top sub thread are well matched with each other before connecting them. 3. Check if the drill pipe and the top sub threead can be fit closely after they are connected.2The external cylinder cracks.The external cylinder is worn out excessively when normally used, and after the normal use dimensiton is exceeded, it fractures normally.Check the using worn condition of the external cylinder frequently, if the normal use dimension has been exceeded (Please see the specific statement in this manual), and replace the external cylinder decisively and accordingly.Beaten by larger external force or grinded by machines.It is forbidden to beat the external cylinder with strong external force, such as a sledge hammer,or to be grinded by machines.Improper torque is forced to applied when it is disassembled or assembled.When it is disassembled with a chain tongs,be sure to apply proper torque and use sharp chain tongs.Welding is carried out on the external cylinder.Welding on the external cylinder is forbidden.3Drive chuck fractures.Applied torque and axial compression are much too large.Reduce propulsion and cornering force.The drive chuck is worn out excessively when normally used, and after the normal use dimensiton is exceeded, it fractures normally.Check the using worn condition of the drive chuck frequently, if the normal use dimension has been exceeded (Please see the specific statement in this manual), and replace the drive chuck decisively and accordingly.

“WORLDRILL”,manufacturing drilling tools, is a leading brand in China, and the DTH Hammers without foot-valve are the most popular products in particular. Compared with the DTH Hammers of the same specification with foot-valve, the advantages of DTH Hammers without foot-valve are as follows: 1. Higher impact frequency and faster drilling speed, with the speed being 15%-20% higher than the ones with foot-valve; 2. Lower air consumption and lower oil consumption, with 10% of the oil consumption saved; 3. Avoid the trouble of foot-valve fracture and expand when heated, or the contraction when cooled; 4. Fewer internal parts, simple in structure, long in service life, and easy to assemble and disassemble. The new type hammer has been well received by users since its launch. Hammering tests have been carried out on the hardest iron ore mine in China. Compared with the products from SANDVIK and ATLAS COPCO, the new type fast hammer produced by our company is about 10% faster in terms of speed. Besides, since the thickness of the external cylinder of the hammer from our company is increased, its service life is longer than others. As to bits, the quality of products provided by our company is comparable to those from the above mentioned two companies; in the meantime, the cost performance of drilling tools branded “WORLDRILL” is much higher than those branded SANDVIK and ATLAS COPCO.Factory and WorkshopPackagingOur Services1.Pre-sale service: Act as a good adviser and assistant of clients enable them to get rich and generous returns on their investments . 1.Select equipment model. 2.Design and manufacture products according to client's special requirement ; 3.Train technical personnel for clients .
