In the maintenance of diesel generating units, often need to clean the surface of the grease, coke, scale and rust and so on. Due to the different nature of the various pollutants, the removal method is not the same. Here are some of the cleaning methods for users to organize, we hope to help:
1, diesel generator sets of oil cleaning methods
Parts of the surface of the oil deposition should be thick when the first scraping, the general should be in the hot cleaning fluid cleaning parts surface oil, commonly used cleaning fluid alkaline cleaning fluid and synthetic detergent. When using alkaline cleaning solution for hot cleaning, heat to 70 ~ 90 ℃, the parts immersed in 10 ~ 15min, and then remove and rinse with water, and then dry with compressed air.
2, diesel generator sets of carbon removal method
Removal of coke can use a simple mechanical removal method, that is, with a metal brush or scraper, etc. to clear, but this method is not easy to remove the carbon deposition, and easy to damage the surface of the parts, it is best to use chemical removal of carbon deposition, Carbon (chemical solution) heated to 80 ~ 90 ℃, the parts of the coke expansion softening, and then use a brush and so on to clear.
3, diesel generator sets scale removal method
Scale chemical removal method is generally used to remove the scale of the chemical solution added to the coolant, the engine work for a certain time, and then replace the coolant, commonly used to remove the scale of the chemical solution are: Gou sodium solution or hydrochloric acid solution, sodium fluoride hydrochloric acid Detergents and phosphoric acid detergents, phosphoric acid detergents are suitable for removing scale on aluminum alloy parts.
