What are the excavator oils? How to maintain more practical is very important

Whether it is lubricating oil diesel or hydraulic oil, oil is important for the maintenance of the excavator. When choosing a variety of oil, the excavator must pay attention to the identification of advantages and disadvantages, especially the novice must be wary of inferior hydraulic oil, oil, diesel, so as not to affect the use of the excavator.

1. Influence of hydraulic oil quality on excavator hydraulic system

Hydraulic oil is the hydraulic medium used in hydraulic system using liquid pressure energy, which plays the role of energy transfer, system lubrication, corrosion prevention, rust prevention and cooling in hydraulic system. The quality of hydraulic oil not only affects the normal work of construction machinery, but also causes serious damage to parts of the hydraulic system. According to statistics, all kinds of faults in the hydraulic system, 60% to 70% are related to hydraulic oil.

2. The impact of lubricating oil quality on excavators

The so-called lubrication is to add a lubricant between the two contact surfaces in relative motion, so that a lubricating film is formed between the two friction surfaces, separating the direct contact surfaces, and becoming dry friction to the internal friction between lubricant molecules to reduce friction, reduce wear, and extend the service life of mechanical equipment. Poor quality lubricating oil will not only damage the rotating parts of the excavator engine, such as the crankshaft, the bearing bush of the connecting rod and other rotating connection parts. Once there is a little problem in these parts, the engine will greatly shorten the service life.

3. The impact of diesel quality on excavator engine

The quality of diesel oil is directly related to the normal operation, operation efficiency and service life of excavator engine. At the same time, it has a direct impact on the economic benefit, project progress and safety production of the construction unit. If the quality of the diesel used by the customer is not up to standard, excessive impurities will also make the combustion incomplete, and excessive carbon accumulation in the cylinder chamber will cause excessive wear of the cylinder liner and piston ring.
