Z12V190B型柴油机从1970年鉴定投产以来已生产数千台,1986年又荣获国家产品质量金质奖。该机主要用作油田钻井动力,也适合于柴油发电机组、内燃机车以及船舶等用途。其主要技术参数为: 缸径/行程/缸壁厚度 190/210/12mm 额定功率/转速 882.4/1500kW/r/min 燃油耗率 209.4+5％ g/kW·h 针对Z12V190B型机缸套穴蚀问题,从1979年开始研究试验和结构改进。广泛调查、解体分析和结构试验,重点对缸套在不同条件下进行振动测试,找出缸套冲击振动是诱发缸
Z12V190B diesel engine has been identified and put into production since 1970, has produced thousands of units, in 1986 won the national product quality gold medal. This machine is mainly used for drilling oilfield, but also for diesel generator sets, diesel locomotives and ships and other purposes. The main technical parameters are as follows: Bore / stroke / cylinder wall thickness 190/210 / 12mm Rated power / speed 882.4 / 1500kW / r / min Fuel consumption rate 209.4 + 5% g / kW · h , From 1979 to study the experimental and structural improvements. Extensive investigation, disintegration analysis and structural testing, focusing on the cylinder liner under different conditions for vibration testing to identify the impact of cylinder liner vibration is induced cylinder
