Product Description YSJ type hydraulic jar is used to free stuck drilling tools in the well. This jar can produce large up-striking force for fishing and coring operations. Through hydraulic principle, a sudden release of the elastic potential energy that accumulates in the drill tool during the hydraulic time delay will create a large up jarring force. The key advantages of YSJ type Z oil jar is that with its simple structure. It provides strong jarring force, is easy to operate and can be easily reset to the pre-load position for consecutive jarring. For better jarring impact, YSJ type Z oil jar is recommended to be used together with the ZSJ type jar intensifier.Working principleAs the piston in the jar slowly moves up the cylinder, the working fluid (hydraulic oil) is pressured and compressed due to its slow out flowing rate. During this hydraulic time delay, elastic potential energy starts to accumulate in the drill tool. When the piston reaches the releasing bore, the hydraulic oil gushes out releasing the pressure, giving the piston a rapid upward load and releasing the elastic potential energy in the drill tool. When the jar pad hits the bottom of the up jar cylinder it creates an impact, this strong dynamic load is then transmitted to release the stuck drill tool. An important feature of this jar is the ease of closing and resetting the tools for consecutive jarring.Specifications-YSJ Type Z Oil JarParameters/TypeYSJ79BYSJ95BYSJ108BYSJ114BYSJ121CYSJ159CYSJ178BYSJ203CYSJ229BProduct Code010100001030000105000010600001081000110100011300001151000116000O.D.
