Two-action Drill Accelerator Type SZJQ

Two-action Drill Accelerator Type SZJQ can be stored energy by hydraulic spring. It should  be applied with  Hydraulic Drilling Jar jointly. The drill collar and Hydraulic Jar (below the Drill Accelerator ) can function an accelerated effect when jarring operates as for making the stuck point gain more jarring force. Meanwhile, it can decrease the damage of tremor produced by up-down jarring for drill tools above Drill Accelerator.   Specifications 型号 Model 外径 O.D. mm(in) 水眼 I.D. mm(in) 接头螺纹Connection  API 最大上击行程 Max. Up-jarring Stroke   mm(in) 最大下击行程 Max. Down-jarring Stroke   mm(in) 水眼压力 Hole Seal Pressure  Mpa(psi) 许用拉力 Max Working Load  kN(lbf) 屈服拉力 Yield Tension   kN(lbf) 许用扭矩 Max Torque  kN﹒m(lbf·ft) 屈服扭矩 Yield Torque   kN﹒m(lbf·ft) 总长  Length   mm(in) SZJQ95 95 (3 3/4) 32 (1 1/4) NC26 178 (7) 178 (7) 35 (5000) 600 (135000) 800 (180000) 4 (3000) 40 (29500) 6651 (261 7/8) SZJQ121 121 (4 3/4) 50 (2) NC38 178 (7) 178 (7) 1100 (247000) 1560 (350000) 15 (11000) 27 (20000) 7185 (282 ¾) SZJQ165 165 (6 1/2) 57 (2 1/4) NC50 165 (6 1/2) 165 (6 1/2) 2000 (450000) 3750 (700000) 25 (18400) 75 (55300) 7476 (294 3/8) SZJQ197 197 (7 3/4) 70 (2 3/4) 6 5/8REG 203 (8) 203 (8) 2600 (585000) 4000 (900000) 30 (22100) 100 (73700) 8000 (315) SZJQ203 203 (8) 70 (2 3/4)    6 5/8REG 203 (8) 203 (8) 2600 (585000) 4000 (900000) 30 (22100) 100 (73700) 8000 (315) SZJQ241 241 (9 1/2) 76 (3) 7 5/8REG 254 (10) 254 (10) 3500 (787000) 5800 (1300000) 40 (29500) 180 (133000) 7259 (285 ¾)
