NR 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.
Advantages:
1. The strong energy of single impact and the low energy consumption in rock crushing;
2. The weight ratio of piston and bit almost reaches 1: 1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and to extended service life of the drilling tool;
3. A good performance in central air exhaust and cuttings discharge, which reduces the repeated crushing of rock;
4. A check valve device is available to drill holes under water.
The NR Series dth hammer, an ideal drilling tool, is widely used in such industries relating to energy, transportation, metallurgy, building etc.
We are mainly manufacturing:
1-12 inch middle-low/high air pressure DTH hammer & bit
Big hole high air pressure DTH hammer using in water well, oil, gas and construction drilling
Eccentric overburden drilling Equipment
Hole opener bit
Rock thread bit
Shank adapter, coupling sleeves and all kinds of adapters
