DTH HAMMER application scope:
Broadly utilized in metallurgical, coal, chemical, constructing materials are not active mines and water conservancy, hydropower, highway and railway protection building initiatives, and many others. Suited for dry wind h2o mixing and shotgun-hole h2o gushing soaked operation, dependable performance, is the perfect drilling hole and rock drilling products.

DTH HAMMER software scope:
When the effect stroke starts, piston and disc are in the higher situation, air pressure passes by way of radial holes in the bonnet and seat into the upper chamber of the cylinder, drive the piston down at high velocity to influence the drill bit. When the piston goes to the spline keyway of the bushing is shut, Stress in the reduced cavity starts to increase, the middle gap at the best of the piston leaves the valve rod, ventilate the higher chamber, drop in stress stop of perform journey. When the piston hits the end of the little bit, because of the upper and reduce strain big difference, the valve disc reverses and the piston returns to the stroke regularly.
