In the repair of coking generator set, it is often necessary to clean the oil stain, carbon deposit, scale and rust on the surface of parts. Due to the different nature of various kinds of dirt, their eradication methods are also different. How to clean generator set parts in multiple aspects?
1、 Oil cleaning
If the oil stain on the surface of the part is thick, it should be removed first. Generally, the surface of parts is cleaned with oil stain. The commonly used cleaning fluids are alkaline cleaning fluid and synthetic detergent. When using alkaline cleaning solution for hot cleaning, heat it to 70~90 ℃, immerse the parts in it for 10~15min, take it out, rinse it with clean water, and then blow it dry with compressed air.
2、 Removal of carbon deposits
Simple mechanical shoveling method can be used to remove carbon deposits. That is, use a metal brush or scraper to remove the carbon deposits, but this method is not easy to clean the carbon deposits, and it is easy to damage the appearance of the parts. Use chemical method to remove the carbon deposit, that is, first use carbon remover (chemical solution) to heat to 80~90 ℃, expand and soften the carbon deposit on the parts, and then use a brush to remove it.
3、 Removal of scale
The generator is generally cleaned by chemical removal method. The chemical solution for removing scale is added to the coolant, and the coolant is replaced after the engine has been operating for a certain time. Common chemical solutions for removing scale include caustic soda solution or hydrochloric acid solution, sodium fluoride hydrochloric acid detergent and phosphoric acid detergent. Phosphoric acid detergent is suitable for removing scale on aluminum alloy parts.
The above are all methods for cleaning all parts during maintenance and repair of generator set. Here, it must be noted that the dirt generated by parts must be cleaned according to corresponding methods. Come to our website for more information http://www.freexbrlonline.com Consult!
