CIR 90 DTH hammer Low pressure DTH hammer is of good quality
Product features of DTH Hammers and bits
What is a low pressure DTH hammer?
Low-pressure DTH hammers are widely used in various hard, high-hardness and other ductile rocks with poor toughness in geotechnical engineering. It has the following characteristics:
1. The low-pressure DTH hammer is a valve-type central exhaust hammer, which has a good effect of discharging rock powder, reducing the re-crushed rock slag, reducing the wear of the drill bit and improving the drilling efficiency.
2. The internal structure of the hammer head is designed with the latest rock design theory, so that the size of the hammer head can obtain the ideal energy transmission, the power of a single hammer head, the drilling speed is faster, and the gas consumption is lower.
3. Selecting the best quality raw materials and the most advanced processing technology, the performance is more stable and the life is longer.
4. It is easy to disassemble and assemble, with low failure and easy maintenance.
