Double Way Hydraulic Shock Absorber

Double Way Hydraulic Shock Absorber

Double way hydraulic shock absorber is worked with cone bit or abrasives core bit to absorb the shock force in vertical and axial direction. It can not only absorb and reduce the vertical shock force and load, and also can absorb and reduce the axial shock loading, so that keep the normal bit pressure and torque. It will realize the best bit pressure and rotate speed in drilling or coring operation. It is better than normal shock absorber on increasing bit working life, protecting the drilling tools and ground equipments, reducing the drilling costs and increasing the drilling efficiency. It is an ideal shock absorber for drill string.
