If the excavator maintenance precautions can be done properly, it can not only prolong the service life of the machine, but also play a positive role in preventing the accidents of the excavator. The reality is that the excavator staff ignore the details of the operation precautions of the excavator and ignore the daily maintenance of the excavator! I would like to emphasize that it is very important to pay attention to the daily maintenance and operation of excavators. Excavators are large-scale power machines with high working intensity, growing up from time to time and great damage. Generally, accidents are caused by negligence in consciousness. Therefore, it is necessary to pay attention to the daily maintenance and operation of excavators!

　　Excavator drivers will maintain their favorite machines after work every day, the most common of which is to clean up the oil and other impurities on the accessories of excavators. Most people think it's a simple and unskilled thing. But when you read this article, you will find that they were washed in vain before.

　　In the real maintenance process, many people are quick and easy, and they often don't pay attention to strengthen the cleaning of excavator parts. In addition, the unreasonable selection of cleaning agent and improper cleaning method directly lead to early wear and corrosive damage of parts.

　　Today's excavator parts compilation mainly summarizes what are the most important parts to be cleaned by your boss when you overhaul the excavator, engine and clean the parts. If the cleaning is not correct, what kind of fault problems will occur.

　　1、 Engine cleaning

　　Carbon deposits in cylinder sleeve steps, piston ring grooves and sundries in bolt holes of excavator accessories are all "corners" that are easily ignored. If these small parts are not cleaned, early wear symptoms such as insufficient bolt torque, easy fracture of piston ring, erosion of cylinder gasket and water inrush will be caused.

　　If it is to clean the external grease of the parts, pour the diesel oil into the spray pot and spray it to the grease place. Wait 10 to 30 minutes, and then perform a scraping. This time, you can use the steel wire ball to scrape the dirt and scrape hard. Generally, the paint will not be scraped off. After spraying the diesel oil and heavy oil cleaner, the butter starts to soften. Repeat the above steps, and then scrape the dirt again. Some of them can't be scraped. At this time, you need to use washing powder to remove the oil stain, and then with the steel wire ball, you can easily remove the oil stain that can't be scraped.

　　2、 Maintenance of other parts of excavator

　　It is not only necessary to clean oil or impurities such as diesel filter, oil filter, hydraulic oil filter, engine water channel, radiator surface, lubricating oil channel, etc. of excavator accessories in time, but also must be careful when cleaning without any omission. Xiaobian has encountered many excavators complaining that the excavators just finished repairing have some troubles, such as car holding and black smoke. In fact, the source of the trouble is that they didn't clean up the parts of the excavators mentioned above.

　　When it comes to cleaning all kinds of excavator parts carefully, then we have to mention the cleaning agent. Although the cleaning agent can only play a simple role in cleaning, there is a lot of knowledge about it!

　　First of all, when the excavator maintenance personnel clean the accessories of the excavator, they should correctly select the cleaning agent! To put it bluntly, different cleaning agents should be selected correctly according to different requirements of parts for cleanliness; secondly, parts should be prevented from corrosion and rusting, especially for precision parts.

　　Secondly, when cleaning, it is not allowed to use alkaline cleaner (especially strong alkaline cleaner) to clean aluminum alloy excavator parts (such as aluminum alloy cylinder head), nor strong acid cleaner to clean copper parts (such as engine thermostat), so as to minimize the corrosion of parts and ensure the service life of parts.

　　Excavator belongs to the special vehicle for construction site. Due to its working environment, the appearance of excavator often has thick dirt. Therefore, it is not easy to clean this kind of heavy special vehicle with our common car washing machine. We should choose the one with pressure of about 150kg, large flow and high cleaning efficiency.
