The Characteristics Of Low Air Pressure DTH Hammer
CR series DTH Hammer, a kind of valve - equipped Low - Air - Pressure hammer with a single piston, a plate valve and a central exhaust structure. The compressed air is adopted as the driving force. To prevent dust pollution and get a better performance, some high - pressure water may be added into the air for wet rock drilling.
It is mainly featured in:
- The strong energy of single impact and the low energy consumption in rock crushing;
- The weight ratio of piston and BIt almost reaches1:1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tool;
- A good performance in central air exhaust and cuttings discharge, which reduces the repeated crushing of rock;
- A check valve device is available to drill holes under water.
The CR Series DTH Hammer, an ideal drilling tool, is widely used in such industries relating to energy, transportation, metallurgy, building etc.
