How to choose a good DTH Hammer
A good DTH hammer should have two indicators: long tool life and high rock breaking efficiency. Previous studies have shown that it is not only the impact frequency and impact energy that affect the performance of the hammer, but also has a close relationship with the weight, shape, stroke size and impact speed of the hammer. On the same hammer, the performance parameters are also interrelated and restricted. When determining the parameters of the hammer, they must be linked, and the matching relationship must be selected. However, the main factors affecting the speed of percussion drilling are impact frequency, impact energy, impact mode and transmission.
Proper and timely maintenance can prolong the life of DTH hammer components and reduce operating costs to a large extent. Clean the parts of the DTH hammer in time. In many cases, the outer casing is worn or the performance of the hammer is reduced due to the wear of the internal parts. At this time, the DTH hammer needs to be repaired and more detailed inspection is required. If all parts are in good condition, you need to apply lubricating oil and install them correctly according to the assembly diagram. However, in order to ensure that your DTH hammer maintains the best performance, you must regularly maintain the DTH hammer.
