Maintenance of generator set is inevitable. Let's briefly introduce the maintenance method.

1、水垢的清除水垢一般采用化学清除法，将清除水垢的化学溶液加入到冷却液中，发动机工作一定时间后，再更换冷却液。常用清除水垢的化学溶液有；苛性钠溶液或盐酸溶液、氟化钠盐酸除垢剂和磷酸除垢剂，磷酸除垢剂适合用于清除铝合金零件上的水垢。

1. The chemical method is generally used to remove the scale. Add the chemical solution to the coolant, and then change the coolant after the engine works for a certain time. The commonly used chemical solutions for scale removal include caustic soda solution or hydrochloric acid solution, sodium fluoride hydrochloric acid detergent and phosphoric acid detergent. Phosphoric acid detergent is suitable for scale removal on aluminum alloy parts.

2、油污清洗零件表面的油污沉积较厚时应先刮除。一般应在热的清洗液中清洗零件苗冕油污，常用的清洗液有碱性清洗液和合成洗涤液。使用碱性清洗液进行热清洗时，加热至70~90℃，将零件浸入10~15min，然后取出并用清水冲洗干净，再用压缩空气吹干。

2. When the oil deposition on the surface of oil cleaning parts is thick, it should be scraped off first. Generally, parts should be cleaned of oil stains in hot cleaning solution. The commonly used cleaning solutions are alkaline cleaning solution and synthetic cleaning solution. When using alkaline cleaning solution for hot cleaning, heat to 70 ~ 90 ℃, immerse the parts for 10 ~ 15min, then take them out and rinse them with clean water, and then blow dry with compressed air.

注意：使用汽油清洗不安全；铝合金零件不能在强碱性清洗液中清洗；非金属类橡胶零件应使用酒精或制动液进行清洗

Note: it is not safe to use gasoline for cleaning; aluminum alloy parts cannot be cleaned in strong alkaline cleaning fluid; non metallic rubber parts should be cleaned with alcohol or brake fluid

3、积炭清洗清除积炭可使用简单的机械情出发，即用金属刷子或刮刀进行清除，但此方法不易将积炭清除干净，而且易损伤零件表面。采用化学方法清除积炭，即先使用退炭剂（化学溶液）加热至80~90℃，将零件上的积炭膨胀软化，然后再用毛刷等进行清除。

3. Carbon deposit cleaning can use simple mechanical conditions, that is, metal brush or scraper to remove carbon deposit, but this method is not easy to remove carbon deposit, and easy to damage the surface of parts. The chemical method is used to remove the carbon deposit, that is, first use the carbon remover (chemical solution) to heat to 80 ~ 90 ℃, expand and soften the carbon deposit on the parts, and then use the brush to remove it.
