Share a few ways to remove the dirt on the surface of Komatsu's genuine accessories
After working for a period of time, Komatsu Genuine Parts will accumulate a layer of grease on the surface of some parts due to oil leakage and oil and gas evaporation. When these impurities are too much, the performance of the diesel engine will be degraded, the fuel consumption will increase, the parts will be worn and corroded, and even Some troubles are caused, so the dirt must be removed in time. The next article will teach you how to properly remove dirt and the use of standards, continue to read the article to understand.
Ways to remove Komatsu pure accessories dirt:
Mechanical removal: The use of steel brushes, sandpaper or abrasive nylon rollers to remove the surface metal of the parts to achieve the purpose of cleaning, the use of this method is more common.
Solvent wiping: Wiping with an absorbent material and rubbing the solvent. Commonly used solvents are petroleum and chlorinated solvents. Many solvents are flammable and can cause fires, so non-flammable solvents should be used. In addition, the type of metal material to be removed should be clarified to keep the parts removed from corrosion.
Alkaline washing: The alkali metal salt is mixed with a surfactant prepared in a suitable ratio. It is effective for removing metal dirt. It is dissolved in hot water and sprayed onto dirty parts. Generally, most of the dirt on the metal surface can be removed. The lowest cost is a suitable method for automatic batch removal.
Pickling: Inorganic acids are usually used, and organic acids can also be used. The purpose of rust removal and descaling can be achieved by adding a wetting agent to the aqueous acid solution.
The reasonable selection criteria for the removal method are as follows:
Removal of carbon deposits: The carbon removal method usually adopts the mechanical cleaning method, that is, according to the material of the machine and the surface shape and quality requirements of the parts, different tools are selected. The commonly used tools are blade, scraper, copper wire brush, copper and aluminum metal sheet. And sandpaper, etc. For engine parts with smooth surface such as aluminum-copper alloy, be careful not to leave scratches when cleaning, because the scratches will make the deposits more likely to accumulate.
Grease removal: The solvents used are usually light diesel oil, kerosene for lamps, solvent kerosene, washing kerosene, industrial gasoline and aviation washing gasoline. Diesel is used to remove general engine parts, and the cleaned parts do not rust quickly. However, the evaporation rate of diesel oil is slower. After cleaning, it should be dried with compressed air as soon as possible to prevent dust pollution in the air. Kerosene and industrial gasoline are used to remove precision parts. The aviation washing gasoline has strong evaporation and is only used to remove special precision. Machine parts.
In the process of removing dirt from Komatsu's genuine fittings, it is generally not limited to one method, but a combination of several methods. Therefore, in the process of use, we should pay attention to the reasonable selection of these methods, the content of the article ends here, if you have other questions, please call us.
