Reverse circulation DTH hammer RC series

Reverse circulation impactor Reverse circulation drilling is also called central sample collection or double wall tube drilling. This kind of drilling usually uses a double wall drill pipe. The drilling power is high air pressure gas, and the high-pressure gas enters the impactor through the gap between the outer tube and the inner tube, so that the percussion drill strikes the rock layer, the broken rock is collected on the drill bit surface, and the air samples are collected through the sample collection pipe and the drill pipe. RC reverse cycle series DTH percussion is the latest development of reverse cycle impactor in our company. It is mainly used for deep hole exploration drilling and core samples. RC series reverse circulation DTH hammer is the latest developed product of our company.It is mainly used for deep exploration drilling and core sampling. It has the following characteristics: 1.Based on previous experience of ordinary hammer,combined with feature of reverse circulation hammer,optimized internal structure and ideal energy transfer,thus ensuring the series of hammers drilling with fast,smooth and continuous sampling. 2.The internal structure is very simple with components of high rigidity,thus ensuring long life and maintenance of the hammer. 3.The collection tube adopts an integrative design and can be replaced without disassembling the hanmmer with catburizing treatment,it has good abrasive resistance. 4.Equipment with bits designed with patent.Simplt by replacing the drill bit,the same hammer can drill holes different sizes ensuring that the sample is not contaminated.
