Shock-absorber naddolotny AN1-165

AN1-165 the Shock-absorber naddolotny with a set of the tool of accessories

The Naddolotny shock-absorber is intended for reduction of shock load of a chisel. Speed of a driving increases by reduction of vibration of configuration of a bottom of a boring column and ensuring use of optimum speed of rotation of a rotor. Isolating the vibration from configuration of a bottom of a boring column caused by a chisel, the shock-absorber reduces the number of accidents of a boring column because of fatigue failures.

The shock-absorber is calculated on effective work at any combination of load of a chisel, pressure difference on a chisel, density of drilling mud fluid or depth of a well. On it force of closing of hydrostatic pressure in a trunk of a well or pressure difference action force does not affect.
