Hydraulic Percussion Apparatus and Method of Use

摘要: A hydraulic percussive apparatus is disclosed for generating vibrating forces to a pipe string. The attached the string central bore through which fluid may be introduced into apparatus. has tubular housing, an anvil surface with irregularly profiled surface, and rotor hammer that urged move axially toward away from surface. longitudinally extending tangentially oriented port in communication longitudinal of rotor. Fluid entering rotor's exiting rotates rotor, thus on moving producing intermittent impact forces.
