在焦化發(fā)電機組修理中，常常需要清潔零件外表的油污、積炭、水垢和銹蝕物等。由于各種污物的性質(zhì)不同，其鏟除辦法也不一樣。那么如何多個方面清理發(fā)電機組零件?

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?

一、油污清洗

1、 Oil cleaning

零件外表的油污沉積較厚時應(yīng)先刮除。一般清洗零件外表油污，常用的清洗液有堿性清洗液和合成洗滌劑。運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潔凈，再用壓縮空氣吹干。

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.

二、積炭鏟除

2、 Removal of carbon deposits

鏟除積炭可運用簡略的機械鏟除法。即用金屬刷子或刮刀等進行鏟除，但此辦法不易將積炭鏟除潔凈，而且易損傷零件外表。選用化學(xué)辦法鏟除積炭，即先運用退炭劑(化學(xué)溶液)加熱至80~90℃，將零件上的積炭脹大軟化，然后再用毛刷等進行鏟除。

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.

三、水垢的鏟除

3、 Removal of scale

發(fā)電機清洗一般選用化學(xué)鏟除法，將鏟除水垢的化學(xué)溶液加入到冷卻液中，發(fā)動機作業(yè)必定時間后，再更換冷卻液。常用鏟除水垢的化學(xué)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鏟除鋁合金零件上的水垢。

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.

以上就是發(fā)電機組維護修理時如何清洗各個零件的全部方法，這里一定要注意零件所產(chǎn)生的污垢一定要按照對應(yīng)的方法去清理。更多相關(guān)事項就來我們網(wǎng)站http://www.pp198.cn咨詢吧！
