one-way shock absorber

Product Description

 

oneway shock absorber is a kind of drilling tool which effects shock absorption by depending on hydraulic oil external force through elastic deformation and damping. With some features of simple construction and easy and reliable operation,it can fully overcome the impact and shocking load from drill strings during drilling operation. Taking use of the shock absorber, it can raise the service life for drill bit and drill tool, speed up drilling, get rid of drilling jumping , well protect surface equipments and drilling tools.
