Road roller air filter replace and cleaning

It is said that the engine is the lung of the road roller, so what causes the road roller to get lung disease? Take humans as an example. The causes of lung disease are dust, smoking, drinking, etc. The same is true for road rollers. Dust is the main cause of lung disease caused by early wear and tear of the engine. The masks worn by harmful substances in the air play the role of filtering out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.

General construction machinery and equipment are mostly used in high-dust working environments such as municipal construction and mines. The engine needs to inhale a lot of air during the working process. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the piston. Group and cylinder wear. Larger particles enter between the piston and the cylinder, and even cause serious “pulling the cylinder”, which is especially serious in a dry and sandy working environment. Installing an air filter is the main method to solve this problem. After the air filter is used for a period of time, with the increase of the amount of dust attached to the filter element, the air intake resistance will increase and the air intake volume will decrease, so that the Engine performance decreases. Therefore, the filter element of the air cleaner must be regularly maintained and maintained. Under normal circumstances, the maintenance cycle of the air filter used in construction machinery and equipment is: clean the outer filter element of the filter every 250 hours, and replace the inner and outer filter elements of the air filter every 6 times or after 1 year.

Cleaning steps of road roller air filter

The specific steps for cleaning the air filter are: remove the end cover, remove the outer filter to clean it, and when removing the dust on the paper air filter, use a soft brush to brush off the dust on the surface of the filter element along the crease direction, and remove the dust from the air filter. Gently tap the end face to dislodge the dust. It should be noted that: when removing dust, use a clean cotton cloth or rubber plug to block both ends of the filter element to prevent dust from falling into the inside of the filter element. Anti-damage filter paper) blow air from the inside of the filter element to the outside to blow off the dust adhering to the outer surface of the filter element. The dry air filter is used to clean the paper filter element with water or diesel oil or gasoline by mistake, otherwise the pores of the filter element will be blocked and the air resistance will be increased.

When to replace the road roller air filter

In the air filter instruction manual, although it is stipulated that the operating hours are used as the data for maintenance or replacement. But in fact, the maintenance and replacement cycle of the air filter is also related to environmental factors. If you often work in a dusty environment, the replacement cycle should be slightly shortened; in actual work, many owners will not make adjustments according to factors such as the environment, and even continue to use the outside of the air filter as long as it is not damaged. It should be noted that the air filter will fail, and maintenance at this time is irreversible. Buying an air filter doesn’t cost much, but if the engine is damaged, it’s not worth the cost. When dedusting the air filter, when it is found that the filter element paper is seriously damaged or damaged, or the upper and lower end surfaces of the filter element are uneven or the rubber sealing ring is aged, deformed or damaged, it should be replaced with a new one.
