Atlas Copco COP1838 Impact Piston 680mm HC Strike Piston

The percussion piston is a key component of the hydraulic rock drill. Impact piston design directly affect the rock drill performance and service life. Rock impact, direct impact of the piston rod adapter, the energy transmitted to the rock drill through the drill pipe and threaded.

HZJX main production rig mines, tunnels, tunnels, quarrying and other related industries, can be designed and manufactured according to special requirements of customers.

Designed of impact piston

1 .

Long and thin shape, reducing unnecessary varying cross-section. Which is more conducive piston impact stress wave propagation, it reduces the peak stress wave, shock wave propagation time increases, the energy transfer efficiency is improved.

2 .

In the percussion piston in the impact head design, designed to be equal or close to the area of the handle adapter, and to obtain a stable small amplitude shock waves, more conducive to smooth transmission.

3 .

Piston face design as much as possible the impact of the center line of the surface of the shank adapter, ensure that the impact of the minimum offset and center in close contact with the surface, more conducive to improving the energy efficiency of transport in the piston. When threaded drill pipe and drill bit to avoid the generation of additional stress.
