Product Detail

 

Full-Hydraulic Drilling Jar QY

 

Full-Hydraulic drilling jar type QY is a double-acting hydraulic jar and is used to free equipment stuck down hole. It can be used with a down hole motor, because it is capable of torque transmission, and is ideal for use in coiled tubing operations, snubbing, rotary drilling and fishing applications. By adjusting the amount of surface push or pull (no torque or external adjustments are required) the operator can deliver very light or maximum impacts in either direction.

 
Features:
 Model “QY” Hydraulic Drilling Jar 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: 30S~240S; the scope of service temperature: -40°C~180°C.
 The scope of outer diameter: 80mm~241mm.
 It can adopt the new special material for higher property and safety.
 It can normally used for drilling, coring, work over and fishing etc.
