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學清除法，將清除水垢的化學溶液加入到冷卻液中，發動機工作一定時間后，再更換冷卻液。常用清除水垢的化學溶液有；苛性鈉溶液或鹽酸溶液、氟化鈉鹽酸除垢劑和磷酸除垢劑，磷酸除垢劑適合用于清除鋁合金零件上的水垢。

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積較厚時應先刮除。一般應在熱的清洗液中清洗零件苗冕油污，常用的清洗液有堿性清洗液和合成洗滌液。使用堿性清洗液進行熱清洗時，加熱至70~90℃，將零件浸入10~15min，然后取出并用清水沖洗干凈，再用壓縮空氣吹干。

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；鋁合金零件不能在強堿性清洗液中清洗；非金屬類橡膠零件應使用酒精或制動液進行清洗

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、積炭清洗清除積炭可使用簡單的機械情出發，即用金屬刷子或刮刀進行清除，但此方法不易將積炭清除干凈，而且易損傷零件表面。采用化學方法清除積炭，即先使用退炭劑（化學溶液）加熱至80~90℃，將零件上的積炭膨脹軟化，然后再用毛刷等進行清除。

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.
