離心式熱油泵+ 常州市武研熱油泵有限公+因為通常咱們軸選用的是護軸布局(不與介質觸摸),因此大多數情況下,軸的選材不耐介質腐蝕的(即是樓主泵的情況),所以假如機封與葉輪輪轂處密封時效,介質與軸觸摸,離心式熱油泵發生腐蝕開裂這是可想而知的,如樓上兄弟所說,軸規劃不合理,懸臂比太大,軸肩處布局規劃不合理(倒圓角太小)發生應力會集。離心式熱油泵工作工況不穩定,徑向力過大等等一些列交變載荷影響下發生疲憊開裂。樓主軸開裂能夠從軸規劃上加粗,查看護軸處密封是不是無缺,軸肩倒圓角加大等辦法處理ecause usually we used is the supporting shaft axislayout (not with medium touch), so in most cases, the shaft material is not resistant to co rrosi on (that is, the landlord pump situation), so if the machine seal and the hub of the impeller seal aging, mediumand shaft touch, co rrosio n cracking this is one can imag ine, such as ups tairs broth ers said , sh aftplan ning unreasonable
