Every day, the excavator driver will carry out some maintenance on his machine after the work is finished. The most common is to clean up all kinds of sludge and oil residue on the machine. Most people will think it's a very simple thing, which doesn't need any technical content, but after reading this article, you may find that the previous ones have been washed in vain.

　　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 maintenance

　　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.

　　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.
