摘要
净水机的高压开关启停运行因系统压差变化会导致增压泵频繁启动或低压保护停止工作,因开关控制元件往复机械运动发生疲劳失效会导致机器持续工作不停机,严重影响产品的正常使用。本文以快插常闭型金属膜片式高压开关为研究对象,采取故障模式及危害性分析(FMECA),使用ANSYS软件对高压开关进行有限元仿真,通过数据分析进行故障定位,提出优化结构设计的解决方案及质量控制措施。
The start-up and shutdown of the high-pressure switch of the water purifier can cause frequent start-up of the booster pump or shutdown of the low-pressure protection due to changes in system pressure difference.Fatigue failure caused by the reciprocating mechanical movement of the switch control components can cause the machine to continue working without stopping,seriously affecting the normal use of the product.This article takes the fast insertion normally closed metal diaphragm high-voltage switch as the research object,adopts Fault Mode and Criticality Analysis(FMECA),uses ANSYS software to conduct finite element simulation on the high-voltage switch,locates the fault through data analysis,and proposes solutions for optimizing structural design and quality control measures.
