DHD350A Rock Blasting Drilling Tools Spare Parts Air Distributor For DTH Hammer

Description:

Two of the biggest challenges in DTH drilling are feed pressure and rotation. To get feed pressure right, gradually increase until you reach maximum operating air pressure. You now have optimum feed pressure and do not need to increase further. When it comes to rotation, it’s all about finding the happy medium. Too slow and productivity suffers. Too fast and you get excessive carbide wear.

But there’s an easy way to find the right speed, using just the air pressure gauge on the drill and a stopwatch!

First, gradually accelerate until you get an increase in penetration rate. Continue until the penetration rate no longer increases. You have now reached optimal rotation speed.

Carbide wear gives a good clue to rotation. The wear should be centered. A worn leading edge indicates too high rotation speed. A worn trailing edge indicates the speed is too low.

Feature Advantage:

· Wire-Line Adaptable.

· Easily Adaptable To All Hdd Drill Rigs.

· Smaller Compressor Requirements (Job Dependent).

· Reduced Operating Cost, No Drilling Fluid Recycling Needed.

· Typically Only One Gpm Of Drilling Fluid For Operation.

· Tested And Proven To Operate In Sands And Cobbles With Proper Drilling Fluid.

· Rate Of Penetration (Rop) Faster Than Conventional Methods.

Application:

Mining, quarry, road building, well hole drilling, blasting, landslide prevention, dam reinforement, anchoring, geothermal, hydrology, etc.
