SUBMERSIONABLE PNEUMO- HAMMER

摘要

This pneumatic hammer demonstrates improved reliability and has a simplified design. It incorporates a hollow case with radial discharge holes where a piston hammer with an axis grove is installed. One chamber is formed in the adapter situated in the upper end of the case, whilst the chamber for the power stroke and the free lift are respectively formed before and after the piston hammer. The air distribution pipe has a piston with axis and radial grooves in its upper end and is positioned along the axis of the hollow case. At the upper end of the air distribution pipe there is a valve box with a piston.
