Preliminary Study on a New Energy-saving Pneumatic DTH Hammer

Abstract:

Pneumatic DTH hammer has disadvantage of low energy efficiency and high air consumption. Differential-volume DTH was presented in the paper, which was totally different to traditional pneumatic DTH hammer with two-side inlet-exhausted structure, the energy efficiency and work efficiency are anticipated 20% higher than DTH hammer.

Key words:pneumatic DTH hammer; high efficiency with less air consumption; differential-volume type; energy efficiency
