不均匀磨损 meaning in English
irregular wear
uneven wear
Examples
- By using finite element method , full - scale tests and the strain survey method , as for the crescent - shaped wear casing , this paper has discussed on mechanism of casing collapse and its influence on casing collapse . furthermore , computing method for both uniform wear and crescent - shaped wear situation was introduced , which can be used directly for casing string design
采用有限元分析、实物试验及实验应变测量方法，研究了套管产生不均匀磨损时的挤毁失效机理及其对套管挤毁性能的影响，确定了均匀磨损和不均匀磨损对套管挤毁性能的计算方法，研究结果可直接用于套管柱强度设计和校核中。 - The highlights of this paper include : hoop toughness criterion for longitudinal heat checking of tool joint was introduced firstly ; failure criterion for crescent - shaped wear casing was established according to the results of full - scale collapse tests ; new - typed alloy for hardbanding of tool joint was developed , its property has showed good performance in the tests
本文的主要创新点在于：以现场失效案例分析为基础，提出了钻杆接头纵向热裂的横向韧性判据；通过对已磨损套管的实物挤毁试验研究，确定了不均匀磨损套管的挤毁失效准则；设计出了具有独立知识产权的钻杆接头硬化带用新型耐磨减摩合金的成分，经实验室试验表明其性能可以达到或超过国外同类产品。 - Supporting roller 12 : it can be dismantled to be repaired if the surface of roller is abraded , or channel of rollers is abraded unequally , or there is sunken hole , make sure that the two roller channels should have same diameter and be coaxial , outer diameter of the pair supporting rollers of every driving roller should be similar
辊面磨损或辊道不均匀磨损或产生凹坑时可拆下精车修理，但注意辊体的二个辊道直径一致并同轴，每个传动辊的一对托辊外径保持一致。
