化工机械密封失效分析和装配质量控制

Mechanical Seals Failure Analysis and Assembly Quality Control of Chemical Enterprises

连续运转的化工生产中经常会存在很多有害的流体,为了防止流体外流,经常会将其密封到装置当中,这使得机械密封装置被广泛应用于化工行业中。本文系统论述了化工机械密封经常使用的方式,并探究了腐蚀、高温等机械密封失效的原因,从密封性能检查以及防止密封泄漏两个方面探究了化工机械密封装备质量的控制方法。

There are often many harmful fluids in continuous chemical production.In order to prevent the outflow of fluids,they are often sealed into the device,which makes mechanical sealing devices widely used in the chemical industry.This paper systematically discusses the frequently used methods of chemical mechanical seals,and explores the causes of mechanical seal failures such as corrosion and high temperature,and probes into the quality control methods of chemical mechanical seal equipment from two aspects ofseal performance inspection and seal leakage prevention.
