POM fuel system
문제 현상
POM fuel pump parts show strength decrease after long-term contact with gasoline
원인 분석
Additives in fuel act on POM for a long time; although the oil resistance is good, specific fuel formulations are erosive; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Select fuel-resistant dedicated grades; verify by fuel immersion aging test; pay attention to fuel formulation changes; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Fuel system parts require dedicated grades plus medium aging verification; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
