Well Drilling Tool Impact Piston For COP 1838ME 3115212900

The impact piston is the key part of the hydraulic rock drill . The design of the impact piston directly affects the performance of the rock drill and its life . When impacting the rock , the piston directly impacts the shank adapter , and the energy transmitted to the rock through the drill rod and the thread bit .

The impact piston designed by HZJX:

1

The shape is long ,thin , and reduces unnecessary cross-section changes . This is more conducive to the transmission of our impact piston stress wave , reducing the peak numerical value of the stress wave , increasing the time of the shock wave to improve the energy transfer efficiency .

2

In the design of the impact head of the impact piston , it is designed to be equal to or close to the area of ​​the shank adapter to obtain a shock wave with small amplitude and stability , which is more conducive to the smooth transmission .

3

The design of the impact end face of the piston is as close as possible to the center line of the impact surface of the shank adapter , ensuring the minimum center offset and tight contact of the impact surface , which is more conducive to improving the energy transfer efficiency of our impact piston.And the additional stress on the drill rod and the thread bit during rock drilling is avoided .
