我场现有4125A 发动机77台,多年的使用证明,其缸套活塞的寿命一般在一年左右,即相当于耗主油12,000—15,000公斤,个别的经一个季度的工作就报废了.而4125缸套活塞的寿命一般在三年左右,即相当于耗主油36,000——45,000公斤。这两种机型缸套活塞的制造工艺,材料都是相同的,甚至是一个厂的产品,为什么使用寿命差别这样大呢?关键的问题是空滤器与发动机不配套。 My current field of 4125A engine 77 units, years of use proved that the life of its cylinder piston is generally about a year, which is equivalent to consuming 12,000-15,000 kilograms of main oil, individual after a quarter of work scrapped, and 4125 Liner piston life is generally about three years, which is equivalent to consuming 36,000 - 45,000 kilograms of main oil. These two models cylinder piston manufacturing process, the material is the same, and even a factory product, why the service life difference so big? The key issue is the air filter and the engine is not complete.
