Common questions about excavator filter elements

Under what special circumstances is it necessary to replace the oil filter element and fuel filter element?

The fuel filter element removes impurities such as iron oxide and dust from the fuel, preventing the fuel system from clogging, reducing mechanical wear, and ensuring the stable operation of the engine.

Under normal circumstances, the replacement cycle of the engine fuel filter element is for the first 250 hours of operation, and then every 500 hours of operation thereafter. The specific replacement time should be flexibly controlled according to different fuel quality grades.

When the filter element pressure gauge gives an alarm or indicates abnormal pressure, it is necessary to check whether the filter is abnormal. If so, it must be replaced. When there is leakage, cracking or deformation on the surface of the filter element, it is necessary to check whether the filter element is abnormal. If so, it must be replaced.

1. Is it true that the higher the filtration accuracy of the oil filter element, the better?

For engines or equipment, the appropriate filtration accuracy of the filter element should achieve a balance between filtration efficiency and ash holding capacity.

Using filter elements with high filtration accuracy may shorten the service life of the filter element due to its low dust holding capacity, thereby increasing the risk of premature clogging of the oil filter element.

1. What are the differences between inferior engine oil and fuel filters and pure engine oil and fuel filters used in equipment?

Pure oil and fuel filter elements effectively protect the equipment and extend its service life.

Poor-quality engine oil and fuel filters cannot protect the equipment well, cannot extend the service life of the equipment, and may even deteriorate the use of the equipment.

1. What benefits can the use of high-quality engine oil and fuel filters bring to machines?

The use of high-quality engine oil and fuel filters can effectively extend the service life of equipment, reduce maintenance costs, and save money for users.

1. If the equipment has exceeded the warranty period and has been in use for a long time, is it unnecessary to use high-quality filter elements?

Equipped with old engines, they are more prone to wear and tear, causing cylinder pulling. Therefore, old equipment requires high-quality filter elements to stabilize the gradual wear and maintain the performance of the engine.

Otherwise, you will have to spend a lot of money on repairs, or you will have to discard your engine in advance. By using pure filter elements, you can ensure that the total operating cost (the total cost of maintenance, repair, major overhaul and depreciation) you spend is the lowest, and also extend the service life of the engine.

1. Can the filter element be perfectly installed on the engine as long as it is cheap?

Many domestic filter element manufacturers simply copy the geometric dimensions and appearance of the original factory parts, but do not attach importance to the engineering standards that the filter elements should comply with, or even have no understanding of the contents of the engineering standards at all. The filter element is designed to protect the engine system. If the performance of the filter element fails to meet the technical requirements and loses its filtering function, the performance of the engine will be significantly reduced and the service life of the engine will be shortened.

For instance, the lifespan of a diesel engine is directly related to the 110-230 grams of dust that is "consumed" in advance due to engine damage. Therefore, inefficient and inferior filter elements will cause more magazines to enter the engine system, leading to early engine maintenance.

1. If the filter elements used do not cause any problems to the machine, then is it unnecessary for users to spend more money on high-quality filter elements?

You may or may not immediately notice the impact of inefficient and low-quality filter elements on the engine. The engine seems to be operating normally, but harmful impurities may have already entered the engine system, beginning to cause corrosion, rusting and wear of engine components.

These damages are hidden and will explode when they accumulate to a certain extent. Although no signs can be seen now, this does not mean that the problem does not exist. Once problems are discovered, it may be too late. Therefore, it is necessary to insist on using high-quality and reliable pure filter elements to protect the engine to the greatest extent.
