The air filter is an important part of the special car, mainly used for air filtration into the engine, with the role of the air filter, in order to ensure that the air into the vehicle engine is clean and sufficient. Air filter is so important, maintenance is essential in the daily use process, then how to maintain the air filter?
For concrete mixing trucks, truck lifting trucks and other engineering vehicles, the air filter is very easy to damage, because the working environment of the engineering vehicle is generally poor, it needs to pay more attention to maintenance in peacetime. Special car air filter is more common is the inertia type air filter, such air filter should be maintained from the following two aspects.
First, the cleaning of the air filter should be orderly:
The cleaning sequence of the air filter is generally:
1. Remove the filter element, plug both ends of the filter element with a clean cloth or rubber plug, brush the dust on the surface of the filter element along the gap direction with a soft brush, and beat the end face of the filter element to make the dust fall off. Compressed air can also be used to blow air from inside to outside the filter element to blow away the dust adhering to the surface of the filter element, and liquid cleaning is prohibited during cleaning to prevent the filter element from adhering to dust and causing blockage.
2. Check whether the main filter element is damaged and whether the upper and lower end faces are warped; Check whether the rubber seal ring of the main filter element is damaged; Check whether there is dust inside the main filter element, if there is any of the above problems, you need to replace the main filter element.
3. Use a strong flashlight to check whether the filter element is damaged, do not remove the safety filter element during the inspection, if the safety filter element is damaged, it should be replaced immediately, in the process of cleaning the filter shell, use a clean cloth to wipe the inner wall of the shell clean, and check whether the dust exhaust valve is normal.
Second, the air filter can not be cleaned too often
If the air filter is cleaned too frequently, the filtration capacity of the filter element will not be fully utilized, which not only increases the amount of dust entering the engine, causing abnormal engine wear, but also causes early damage to the filter element. After each cleaning of the filter element, its ash capacity will be reduced by 20%-40%, with the increase of cleaning times, the ash capacity of the filter element will gradually decrease, when the filter element is cleaned 5 times, the ash capacity is basically no, at this time it must be replaced by the air filter.
Air filter is a kind of stirring truck accessories, although the price is not expensive, but if the damage will seriously affect the normal work of the engine, so it is recommended that friends driving engineering vehicles must regularly clean the air filter.
