The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

  • Since hose may change in length from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
    Never use a bending radius less than the minimum shown in the hose specification tables. The bending radius of the hose should be far away from the hose fitting (A>1.5R)
    Hose bending radius is bigger when it is in motion.
    Choose proper fittings, avoid twisting in hose lines bent in two planes.
    Avoid twisting in hose by use clamp properly.
    Hose should not be twisted, hose is weak when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
    Leave proper length when the hose in connected
    Choose proper fittings, avoid too small bending radius and excess force.
    Choose proper fittings, avoid excessive hose length.
    Reuse friction, avoid hose touching the object directly or far away from the object.
    Hose Active Working Pressure Working Life
