Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt
文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。Abstract : factors causing the failure of the rod string in a screw pump well include rod with minor od being used ， defects in the rod body produced in manufacturing and service ， excessive torque caused by plugging and reactive torque on the rod string ， and excessive shearing stress on the rod thread
文摘:造成螺桿泵採油井抽油桿桿柱斷裂、脫扣和擼扣的主要原因有桿體外徑選擇偏小，桿體製造或使用過程中產生缺陷，堵塞扭矩過大，反扭矩大於螺紋聯接扭矩以及抽油桿螺紋牙受剪應力過大等。This kind of testing machine is composed of mechanical support system, bend moment and torsion loading and controlling system, bend moment and torsion measure system, and auto - detection, auto - power - cut and auto - count system when the specimen broken
