PPO Water Meter and Pump Housing Application
Problem Phenomenon
【Problem Phenomenon】Water meters and pump housings are in long-term hot water environments; metal is heavy and corrodes, and ordinary plastics creep
Cause Analysis
PPE/HIPS has low water absorption, hydrolysis resistance and dimensional stability, suitable for water meters, pump housings, pipeline parts and fluid handling equipment; can replace stainless steel and reduce weight; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
Select PPO series for water contact parts and conduct long-term hot water verification; select certified grades for drinking water applications; utilize low expansion when mating with metal inserts; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Water meters and pump housings are PPO's home field; hydrolysis resistance and dimensional stability replace stainless steel; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
