Insufficient equipment maintenance during linear low-density polyethylene linear low-density polyethylene processing (variant: strengthened measures)
Problembeschreibung
Equipment failures occur frequently, product quality fluctuates, and production efficiency is low.
Insufficient maintenance leads to reduced equipment precision, worse plasticization quality and increased energy consumption.
Especially, additional attention is needed on top of the original basis; this problem is more prominent and requires focused attention.
Ursachenanalyse
(1) Equipment runs for a long time without periodic maintenance
(2) Screw and barrel wear is not inspected and replaced in time
(3) The mold is not regularly maintained and polished
(4) Sensors and instruments are not regularly calibrated
(5) Lubricating oil is not replaced on time, causing mechanical parts to wear
(6) On top of the original basis, additional attention is needed as process parameter fluctuations or equipment condition changes aggravate this problem
Lösung
(1) Establish an equipment preventive maintenance plan with monthly, quarterly and annual maintenance
(2) Regularly check screw clearance (not exceeding 0.2mm) and barrel wear
(3) Perform maintenance and polishing on the mold every 100,000 shots
(4) Calibrate temperature sensors and pressure sensors quarterly
(5) Establish equipment archives to record maintenance history
(6) And strengthen process monitoring; on top of the original basis, additional attention is needed to pay special attention to parameter stability
Wichtigste Erkenntnis
Equipment maintenance is the foundation of stable production; a standardized regular maintenance system and record system need to be established.
In different production scenarios, targeted preventive measures need to be taken.
