軸襯材料
目前在AF泡沫泵類產(chǎn)品上，應(yīng)用量大面廣的軸襯是鑄造軸承合金，稱巴氏合金(白金、鎢金)，它可以分為錫基合金和鉛基合金兩種。前者的強度、硬度、沖擊韌性、耐蝕性和鑄造性能均優(yōu)于后者，故錫基巴氏合金的應(yīng)用約占2/3，如Z5nSb1Cu6 (83)和ZSnSb8Cu4 (o89)， 但鉛基巴氏合金在滑動性能方面又優(yōu)于錫基巴氏合金,使用起來也比較經(jīng)濟，所以鉛基巴氏合金的應(yīng)用也占1/4左右.
Liner material
At present, on the AF foam pump products, a large amount of bushing is used to cast the bearing alloy. It is called Babbitt alloy (platinum and Wu Jin). It can be divided into two kinds: tin based alloy and lead based alloy. The former is superior to the latter in strength, hardness, impact toughness, corrosion resistance and casting properties, so the application of tin-based pasteurized alloys accounts for about 2/3, such as Z5nSb1Cu6 (83) and ZSnSb8Cu4 (o89). However, the sliding properties of lead-based pasteurized alloys are better than that of tin-based pasteurized alloys, and the application of lead-based pasteurized alloys is more economical.
