Product details



The new diamond DTH percussion device is widely used in geotechnical engineering to wear a variety of hard, hard and other hard to drill tough rock. The low-pressure impactor is a valve-type center exhaust impactor, which has good effect of discharging rock powder, reduces the repeated crushing of the rock residue, reduces the wear of the drill bit and improves the drilling efficiency; adopts the new drilling theory to design the interior of the impactor Structural size, the impact of the hammer to obtain the ideal energy transfer, a single impact power, drilling faster, lower consumption of air consumption; selection of high quality raw materials and advanced processing technology, more stable performance and longer life expectancy. Disassembly easy, low failure, easy maintenance. Suitable for mining, quarry, road and other projects drilling blasting holes, landslide protection, dam reinforcement, anchoring and other engineering holes, geothermal air-conditioning, hydrology, water wells and other fields.

 

It is a kind of valveless high air pressure DTH hammer with foot valve.It has the following advantages:


   The main features are as following:
   1.Valveless air distribution.More reliable.
   2.Simple design of the piston.long life span.
   3.More effcient energy transfer,faster drilling speed,lower air consumption and lower oil consumption.
  4.Fewer intemal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat trated.
  5.Easy to disassemble because the top sub,the drive chuck and the extemal cyinder are connected by muitiple steps thread.


 

The appearance of the picture is different from that of the actual product, and the actual product is the standard.
