In order to ensure the safe operation of the machine and avoid the occurrence of machine failure and shutdown caused by high temperature. This article will explain the inspection of excavator engine oil in summer and the points that should be paid attention to when selecting lubricating grease, for reference only.
1. Check engine oil
As the temperature rises, the viscosity of engine oil will decrease, and the use of low viscosity four season engine oil will affect the engine. General four season engine oil is suitable for use in areas with temperature of – 25 ℃ – 40 ℃. In areas with higher temperature, replace with special summer engine oil of higher grade. And replaced every 250 hours.
2. Selection of lubricating grease
The working temperature of excavator will be higher when the ambient temperature is high in summer. Temperature has a great influence on the fluidity of grease. With the increase of temperature, the lubricating grease becomes soft, which reduces the adhesion of the lubricating grease and is easy to be lost, resulting in the decrease of the lubricating performance of the working device and the rotary device. In addition, under higher temperature conditions, the evaporation loss of grease is easy to increase. Oxidation deterioration and condensation oil separation are serious. The main reasons of grease failure are mostly due to the shrinkage of gel and evaporation loss of base oil. The grease with good high-temperature performance can maintain its adhesion performance at higher service temperature, and its deterioration and failure process is also slow.
