DTH HAMMER application scope:
Widely utilised in metallurgical, coal, chemical, creating resources are not busy mines and h2o conservancy, hydropower, highway and railway protection design tasks, and many others. Suited for dry wind h2o mixing and shotgun-gap drinking water gushing soaked procedure, reliable efficiency, is the ideal drilling gap and rock drilling equipment.

DTH HAMMER software scope:
When the influence stroke starts, piston and disc are in the upper position, air stress passes via radial holes in the bonnet and seat into the upper chamber of the cylinder, drive the piston down at substantial velocity to impact the drill little bit. When the piston goes to the spline keyway of the bushing is closed, Stress in the reduced cavity begins to increase, the middle gap at the top of the piston leaves the valve rod, ventilate the upper chamber, drop in force conclude of function trip. When the piston hits the conclude of the little bit, due to the fact of the higher and reduced stress big difference, the valve disc reverses and the piston returns to the stroke repeatedly.
