1987年12月,我公司一台东德UB-162-1型30t履带吊发动机曲轴断裂,喷油泵性能下降,经多方联系,在国内未找到同一规格进口件(曲轴、喷油泵、发动机),若向国外订货,需二年以上才能到货,另外,性能相似的国产电动机亦缺货,所以我们决定采用库存的常州冶金机电厂产6135型柴油机替换原机。虽然6135机功率比原机功率小7%,且转速高了600r/min,由于原机是作为挖掘、起重两用机,其挖掘所需马力较大,行走和起重所需马力较小,本机换装后,仅用
In December 1987, the crankshaft of a 30t crawler crane engine of East Germany UB-162-1 was broken, and the performance of the fuel injection pump was reduced. After many contacts, no imported parts of the same specification (crankshaft, fuel injection pump, engine) were found in China. If you order to foreign countries, it takes more than two years to arrive. In addition, domestic motors with similar performance are also out of stock, so we decided to use the inventory of Changzhou Metallurgical Plant to replace the original 6135 diesel engine. Although the 6135 machine power is 7% lower than the original machine’s power, and the speed is 600 r/min higher, because the original machine is used as an excavating and lifting machine, the horsepower required for excavation is relatively large, and the horsepower required for walking and lifting is small. , After the machine is changed, only use
