离心机用0Cr18Ni9不锈钢腐蚀失效分析

螺旋卸料沉降式离心机具有连续进料、螺旋推进、高速运转等特点.卧式螺旋卸料沉降式离心机已经在农业、化工、轻工等部门广泛应用.作为离心式分离设备,其高速旋转的转鼓能产生极大的离心力,以完成各种物料的液-固及液-液分离.作为核心部件的转鼓必须满足3个条件：耐腐蚀、高强度及低能耗.只有三者兼备,才能保证离心机的使用性和安全性.同时,为保证焊接区域的整体性和使用的稳定性,应使用合理的焊材和焊接工艺.

Failure of 0Cr18Ni9 stainless steel used in centrifuge

Spiral discharge sediment centrifuge is characterized by its high speed, continuous filling, and propellers for discharging. The centrifuge produced is horizontal Spiral discharge sediment centrifuge, which is now widely used in chemical industry, medicine industry, light industry and other industrial territories. As the centrifugal separation equipment marked with high efficiency and low-energy consumption, high-speed running scroll can produce powerful centrifugal force, which can ensure the liquid-solid process of all materials, and liq- uid-liquid separation. As the core components, the scroll must meet three conditions- corro- sion resistance, high intensity, and low-energy consumption. The usage and security of cen- trifuge could not be ensured without the combination of the three conditions.
