If the diesel filter element is not replaced in time or the inferior filter element is used, the engine may not be abnormal in a short time. But if it is operated in this way for a long time, the probability of engine damage will be greatly increased. This article will mainly explain the misunderstanding in the process of filter element replacement and use.
1. Use cheap filter elements, as long as the diesel filter element is often replaced
In fact, the quality of diesel filter element is not only related to the service life, but also the filtration efficiency of diesel filter element. The filtration efficiency of inferior filter element is very low. Using this kind of filter element for a long time, even if the replacement time is shortened, it cannot achieve good filtration effect. It will even lose the function of protecting the fuel system.
2. As long as there is no problem with the engine, do not rush to replace the diesel filter element
All brands of excavators have strict standards for the replacement time of diesel filter elements. The purpose is to filter the impurities in diesel oil more effectively. If the diesel filter element is not replaced for a long time, it will cause damage to the fuel system. However, many people can't see any abnormal phenomena in the engine in a short time, so they don't replace the diesel filter element in time for efficiency reasons. When the engine is worn to a certain extent, the oil pump nozzle must be replaced.
3. You don't need to drain water every day. You can drain water when you have time
Diesel oil contains water in daily use. At the same time of engine maintenance, the diesel filter element should be drained every day. If the diesel filter is not drained regularly, it will cause damage to the fuel system, and then the engine will suffer various damages. Therefore, the diesel filter element is generally replaced every 250 hours, and the diesel filter element should be drained every day, so as to avoid failure. The replacement time of filter element is related to the working condition and the quality of fuel injected. The specific time shall be subject to the actual situation.
