Engine oil change can be said to be an important part of the maintenance of excavators, and its importance is most clear to all of you. Besides lubricating the engine, oil also has the functions of cleaning, cooling, rust prevention, sealing, oxidation resistance and buffering.
Therefore, the normal operation and service life of the engine are closely related to the oil. In general, the operation of oil change is very simple, it is not difficult for everyone, but some of the key points that need to be noticed may be ignored, and it may not be clear to the novice.
The brick makers today will explain in detail some points for attention to changing the oil, and teach you how to correctly replace the oil and maintain the engine.
Oil as a consumable for engine maintenance, regular replacement must be done. Some owners in order to save maintenance costs, overdue use of oil, but I do not know may have caused damage to the engine.
We all know that the main function of the oil is lubrication. In the long term use of the engine, the viscosity of the oil will gradually decrease, and the lubrication effect will be lost in the end. If no replacement is used, the engine parts will be worn, and if the oil contains impurities, the long work will cause the cylinder.
So the oil filter element must also be replaced on time as oil. Each quality of the oil replacement cycle is different, such as the best quality CI-4 grade oil, the replacement period can not exceed 500 hours, other quality oil replacement time is shorter, if the working condition is not good, the time should be shortened.
The oil market can be said to be mixed, counterfeit 名媛直播 are numerous, and the quality is difficult to guarantee. So when you buy oil, you'd better go to the regular brand oil agency to buy it.
Although the price is more expensive than the miscellaneous oil, but the quality is much better, if the poor quality of oil not only can not protect the engine, and will also cause wear and tear to the engine, it is not worth the loss, so the brick house reminded everyone should not be greedy for urine.
When we are adding oil, we can't add another grade of oil, whether it's the same brand or other brand manufacturers, if it is not added in half. Even with the same grade of oil, you should choose the same brand manufacturer instead of other brand manufacturer's oil.
Because different levels of oil used in the production process are different additives, different manufacturers have different formulations. If mixed together causes chemical reaction, it will damage the engine.
There are many misunderstandings when engine changes oil. Some of you think that the more oil you have, the better. More oil will also cause bad damage to the engine, for example, excessive oil will reduce the output power of the engine, and also increase the fuel consumption, appear blue smoke and noise and other phenomena.
Secondly, too much oil may cause piston ring to bite and nozzle blockage. So in order to prevent the oil more effectively, we should use the method of less and many times, and wait about 5 minutes after the injection, observe the oil level on the oil scale, check if the oil level is in the normal oil position, and if not, continue to make sure that the oil level is not lower than the minimum scale. It must not be higher than the highest scale line at normal oil level.
