Full-Hydraulic Drilling Jar Type QYⅡ

Full-Hydraulic Drilling Jar Type QY 

The up-down jarring of Full-Hydraulic Drilling Jar Type QYII can be acted  hydraulically, realizing the stepless control of up-down jarring tonnage. It can protect the drill string effectively and improve the using life. The hydraulic stored energy mechanism has the advantage of reliable property and good stability. The scope of time delay interval can be 30s~240s;the scope of service temperature can be -40℃~180℃. It can adopt the new special material for higher property and safety. It can normally used for drilling, coring, work over and fishing etc.
