One-Way Shock Absorber(YJ Type) basic infomation

One-Way Shock Absorber(YJ type)
 

YJ type one-way shock absorber is a kind of drilling tool which effects shock absorption by depending on hydraulic oil under external force through elastic deformation and damping. With some features of simple construction, 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.
