4 Inch 102mm Dth Hammer Usage:
Widely used in metallurgy, coal, chemical industry, building materials not busy mines and highway, railroad, national defense, construction and other engineering hole-forming operations, suitable for dry, mixed wind and water and gunhole gushing water wet operation, reliable work performance, is the ideal drilling and drilling gunhole equipment today.
4 Inch 102mm Dth Hammer Advantage:
As specialist manufacturer and provider of DTH drilling tools, hereby we recommend our newest generation DTH hammer which is improved by absorbing art technology, selecting superior alloy steel and robust design. It is proved by more than thousands times of test that our newest DTH hammer has longer life , lower air consumption and 15% higher penetration speed compared the conventional DTH hammer in the market.
4 Inch 102mm Dth Hammer Theory:
At the beginning of the impact stroke, the piston and valve piece are in the extreme upper position, and the pressure gas enters the upper chamber of the cylinder through the radial hole of the valve cover and valve seat, pushing the piston to move downward at high speed to impact the drill bit. When the piston travels to the spline groove of the bushing and is closed, the pressure in the lower cavity starts to rise, so the center hole of the upper end of the piston leaves the air distribution rod, making the upper cavity open to the atmosphere, the pressure decreases and the working stroke ends. When the piston impacts the end of the drill bit, the valve piece, due to its upper and lower pressure difference, reverses direction and the piston repeats the return stroke movement.
