Item Description

-Merchandise Short-

The drill human body of the solution is 42crmo. 42CrMo metal belongs to ultra-large-power steel, with high power and toughness, great hardenability, no evident mood brittleness, high fatigue limit and resistance to several impacts following quenching and tempering. Capacity, minimal temperature impact toughness is very good. The metal is ideal for the manufacture of massive and medium-sized plastic molds that call for certain strength and toughness. Alloy grade: YK05

DTH HAMMER software scope:
Widely utilised in metallurgical, coal, chemical, building supplies are not active mines and drinking water conservancy, hydropower, freeway and railway protection development projects, and so forth. Suitable for dry wind h2o mixing and shotgun-gap drinking water gushing moist procedure, reputable performance, is the best drilling hole and rock drilling gear.

DTH HAMMER software scope:
When the affect stroke starts, piston and disc are in the upper placement, air pressure passes through radial holes in the bonnet and seat into the upper chamber of the cylinder, drive the piston down at higher pace to affect the drill little bit. When the piston goes to the spline keyway of the bushing is closed, Pressure in the reduce cavity begins to rise, the heart hole at the best of the piston leaves the valve rod, ventilate the higher chamber, drop in stress finish of function excursion. When the piston hits the stop of the little bit, due to the fact of the higher and lower stress distinction, the valve disc reverses and the piston returns to the stroke repeatedly.
