南京地铁1号线国产轮缘润滑块具备替代进口件的条件。通过近一年的国产化试验,原始数据证明国产润滑块无论在每万公里消耗上,还是在对轮缘的减磨效果上都能达到期望值,亦未发生固死故障、掉块、断裂等现象。与进口轮缘润滑块的技术参数对比,在保证使用安全、高效的同时,在经济效益和采购周期方面也效果显著。国产润滑块各项技术指标均优于进口产品。
Nanjing Metro Line 1 domestic rim lubricating blocks have the conditions to replace imported parts. After nearly a year of localization test, the original data proves that the domestic lubricating block can reach the expected value no matter the consumption per 10,000 kilometers or the anti-friction effect of the rim, and there is no solidified failure, falling block, fracture, etc. phenomenon. Compared with the technical parameters of the imported rim lubrication block, it is also effective in terms of economic benefits and procurement cycle while ensuring safe and efficient use. The technical indicators of domestic lubricating blocks are better than imported products.
