PPO High-Temperature Resistant Gears, Fan Blades and Valves
Problem Phenomenon
【Problem Phenomenon】Material selection for gears, fan blades and valve parts used at relatively high temperatures
Cause Analysis
PPO has high rigidity, high heat resistance and wear resistance, and can be used as gears, fan blades, valves and other parts used at relatively high temperatures, and can replace stainless steel; dimensional stability ensures transmission accuracy; 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 glass fiber reinforced grades for heat-resistant transmission parts; check according to PV value and temperature; check creep when replacing metal; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PPO makes heat-resistant gears, fan blades and valves; dimensional stability is the capital of transmission parts; 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
