由长沙铁道学院科研所与戚墅堰机车车辆工艺研究所共同研究、金城江机务段协作完成的“激光硬化大功率柴油机活塞环”科研成果,于1986年11月15日由湖南省教委主持通过省级技术鉴定。大功率柴油机活塞环是在高温、高压和带腐蚀性燃气的汽缸中作往复式运动,在与缸套接触面上受力的作用,作滑动摩察时引起摩损,当摩损到一定程度后产生漏气,密封性能降低,从而导致机车牵引功率下降,油耗增加。长期以来,因活塞环耐摩性达不到要求,不得不在
Research Institute of Changsha Railway Institute and Qishuyan Rolling Stock Technology Research Institute jointly completed the Jinchengjiang locomotive collaboration completed “laser hardening high-power diesel piston ring” scientific research, in November 15, 1986 chaired by the Hunan Provincial Education Commission through the provincial Technical appraisal High-power diesel piston ring is in high temperature, high pressure and corrosive gas cylinder for reciprocating motion, the contact surface with the liner on the role of force for sliding friction caused by friction, when the friction loss to a certain extent After the resulting leak, reduce the sealing performance, resulting in locomotive traction power decline, fuel consumption increased. For a long time, due to the piston ring resistance to meet the requirements, had to
