Spare Parts Cleaning - an Important Part of Generator Maintenance

The service life of diesel generating set is generally long, to use fixed number of year is a long time of diesel generator set, its appearance is usually accumulated a certain amount of dirt, the various parts of the system is also possible oil, carbon deposition and scaling and so on, in order to ensure the unit when use can run normally, Dingbo Power remind you: regular diesel generator set accessories for cleaning and maintenance of the important content. The following Dingbo Power for you to introduce the correct treatment of these three kinds of dirt.

The oil cleaning

When the oil stains on the surface of parts of diesel electric generator are thick, they should be scraped away first. Generally, oil stains on the surface of parts should be cleaned in hot cleaning liquid. The commonly used cleaning liquid is alkaline cleaning liquid and synthetic detergent. When using alkaline cleaning solution for hot cleaning, heat to 70~90℃, immerse the parts for 10~15min, then remove them and rinse them with clean water, and then blow dry them with compressed air.

Note: It is not safe to use gasoline for cleaning; Aluminum alloy parts can not be cleaned in a strong alkaline cleaning solution; Non-metallic rubber parts should be cleaned with alcohol or brake fluid.

Carbon deposit to clear

The removal of carbon can be done by simple mechanical removal method, that is, metal brush or scraper, but this method is not easy to clean the carbon, and easy to damage the surface of parts. It is best to use chemical methods to remove carbon, that is, the first use of carbon removal agent (chemical solution) heated to 80 ~ 90℃, the carbon on the parts of the expansion and softening, and then with a brush to remove.

Removal of scale

Scale is generally used by chemical removal method, the chemical solution of scale removal is added to the coolant, and the coolant is replaced after the engine in the diesel generator set works for a certain time. The commonly used chemical solutions for scale removal are caustic soda solution or hydrochloric acid solution, sodium fluoride hydrochloric acid scale remover and phosphate scale remover, which is suitable for the removal of scale on aluminum alloy parts.

In diesel generator set for spare parts to unpick and wash, we will pay attention to the steps and technology, especially for the bearings, precision parts, hydraulic components, seals and parts with special cleaning requirements is more important, isn't doing a good job cleaning, can make the bearing heating and premature loss of accuracy, also because with dirt and burr scratch the surface, Make the relative sliding face appear to grind, and even occlude and other serious accidents, therefore, users must pay attention to the regular cleaning of diesel generator set accessories.
