Low air pressure DTH hammer
HR 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.
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 the extended service life of the drilling tools;
3.A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock;
4.A check valve device is available to drill holes under water.
