HDPE pipe cooling
문제 현상
HDPE pipe cools out-of-round, and the ovality exceeds the standard
원인 분석
The water temperature and spraying of the cooling water tank are uneven, and the pipe shrinks differently in each direction; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Uniform cooling water temperature; full spray coverage; stable sizing sleeve vacuum; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, to facilitate locating effective measures
핵심 요약
Pipe roundness relies on cooling uniformity and sizing stability; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
