本文叙述用常规配机计算，探明拆旧VTR630型增压器在一定运行范围内可配用于国产6ESDZ76/160型低速柴油机，在该运行范围，其性能符合船主要求．6年多的运营实践证明该配机成功．从而，解决了用户燃眉之急，避免了由于停航和进口增压器所带来的经济损失，也为国内航运界拥有的几十条万吨级货轮所用同类主机改用该类旧增压器开创了先例· This paper describes the use of conventional machine calculation, proven demolition of the old VTR630 turbocharger in a certain range of operation can be used with domestic 6ESDZ76 / 160 low-speed diesel engine in the operating range, its performance in line with the requirements of the owner. More than 6 years of operational practice proved that the allocation machine was successful. As a result, the urgent need of users has been solved, avoiding the economic losses caused by the suspension and import of turbochargers, as well as the switch of similar turbochargers for dozens of 10,000-ton freighters owned by the domestic shipping industry precedent·
