The maintenance of the excavator is not in place, which directly affects the service life of the machine. The air filter element is like a checkpoint for the air to enter the excavator engine, which will filter out the impurities and particles therein, so as to ensure the normal operation of the engine. How to properly maintain the air filter and extend the service life of the air filter?
Now, many old excavator drivers know a simple way to extend the life of the air filter, this method is to use compressed air to directly blow off the dust inside the air filter, in order to achieve the goal of extending the life of the air filter! But in fact, this is really not a good method.
Let ’s first explain why we ca n’t do this. In fact, all of this must start with the function of air filter:
The main function of the air filter is to ensure high-efficiency fuel combustion. The air filter is at the front end of the entire combustion process and is used to reduce impurities entering the combustion chamber air.
A standard air filter consists of three parts:
1. Structural parts
2. Filter material to ensure that impurities in the air cannot pass through
3. Sealing ring
No matter which of the three is damaged, it will lead to air filter failure, resulting in air can enter the engine directly without air filter
Now let’s return to the topic just now. Never use compressed air to clean the air filter as a money-saving technique, because this will cause the filter fibers in the filter material to be damaged. If there are holes in the filter material, it will further lead to The air filter is invalid. It may save you a small amount of money to buy the air filter, but it will soon bring danger to the engine, then you can think of this large expenditure.
Therefore, the most correct way to maintain the air filter is to regularly check and maintain it according to the operating instructions; when replacing the air filter, be sure to choose regular products, which not only guarantee the quality, but also have a long service life. A high-quality component will ensure that your assets are in good working condition for a long time.
So, what issues should be paid attention to when replacing the air filter element of the excavator? Let’s take a look together below:
1. Counterfeit filter elements cannot be used, because the filtering effect and sealing are relatively poor, and dust will damage the engine after entering.
2. It is necessary to check whether the sealing part of the new filter element adheres to dust or oil stains, and if necessary, clean it.
3. When inserting the filter element, if the rubber at the end expands, or the outer filter element is not pushed right, and the cover is firmly attached to the buckle, there is a risk of damage to the cover or filter housing.
