工程机械用柴油机润滑系统常见故障原因分析

Analysis of common failure causes of diesel engine lubrication system forconstruction machinery

润滑系统在发动机中起着润滑、冷却、清洗、密封、防锈等功能,润滑系统工作正常是保证柴油机正常运转的必要条件之一,不良的润滑会极大的缩短柴油机的使用寿命。本文就工程机械用柴油机中润滑系统常见的结构类型,对润滑系统的常见故障:机油压力偏高或偏低、机油消耗量过大、机油温度过高、机油变质等故障原因进行了分析,并从常规保养、检查、清洗、免解体维护等方面对如何降低润滑系统故障提出了一些措施。

The role of the lubrication system in the engine is lubrication、cooling cleaning sealing rust prevention,etc.Normal operation of the lubrication system is one of the necessary conditions to ensure the normal operation of the diesel engine.Poor lubrication will greatly shorten the service life of the diesel engine.This article discusses the common structure types of lubrication systems.Analyze common faults of lubrication system:high or low oil pressure,excessive oil consumption excessive oil temperature,deterioration of oil,etc.From routine maintenance,inspection,cleaning,disassembly-free maintenance,etc.Some measures are proposed on how to reduce the failure of the lubrication system.
