快换接头失效案例分析

Fault Analysis for Quick Coupling

快速接头广泛应用于各个行业。某连铸机在使用过程中发现快换接头存在断开时漏油,易污染,对接、断开困难,故障率高等问题。经失效分析,发现是快换接头选型及使用不当造成的。正确的选型和使用不仅可以提高系统工作效率,也能大大减少维护成本。

The quick couplings are widely used in varies industries. The case of quick coupling frequent failure on con-caster in steel mill was introduced,including leakage,contamination,difficult to connect/disconnect. Through detailed failure analysis,it was found the failure was mainly caused by improper choosing and using. Correct selection and handling can reduce failure frequency,maintenance cost,and improve system efficiency on time.
