Cleaning and maintenance of the "three filters" of small excavators:
The three filters of small excavators are mainly air filters, diesel filters and oil filters. This is one of the tasks that our machine friends often come into contact with, but do you know the maintenance methods of these three specific filtering processes?
The so-called "three filters" are air filters, diesel filters and oil filters connected to air filters. "Three filters" are cleaned in time, which helps to completely improve engine performance, reduce engine failure rate and extend engine life. The following is an engineer's introduction of a small hydraulic excavator.
1. Keep the air filter of the small excavator clean
Too many air filters will hinder the inflow of external air and affect the mixing ratio of air and diesel. According to the test, about one gram of diesel is completely burned, and about fifteen grams of air are required. If there is a lack of air in the cylinder, the mixture will not be completely burned, the diesel will be wasted, the engine power will be insufficient, and most of the HC and CO components in the exhaust gas will also be polluted.
The air inevitably contains dust and other impurities, which depends on the soil, climate and road conditions in the area. Tests have shown that when driving on dusty roads, the air filter can filter 0.4 to 1.8 grams of dust per cubic meter of air. In terms of chemical composition, most of this dust is silicon dioxide. Once it enters the friction surface, it will penetrate the lubricating oil film, increase the wear of the engine cylinder, and shorten the engine life.
