Insufficient equipment maintenance in heat-resistant polyethylene heat-resistant polyethylene processing (Variant: strengthened measures)
Fenómeno del problema
Equipment failures occur frequently, product quality fluctuates, and production efficiency is low.
Insufficient maintenance leads to decreased equipment accuracy, worse plasticizing quality and increased energy consumption.
Especially on the original basis, additional attention is needed, and this problem is more prominent and requires key attention.
Análisis de la causa
(1) Equipment running long-term without periodic maintenance
(2) Screw and barrel wear not inspected and replaced in time
(3) Mold not regularly maintained and polished
(4) Sensors and instruments not regularly calibrated
(5) Lubricating oil not replaced on time, mechanical parts worn
(6) On the original basis, additional attention is needed: process parameter fluctuations or equipment state changes aggravate this problem
Solución
(1) Establish an equipment preventive maintenance plan, monthly, quarterly and annual maintenance
(2) Regularly check screw gap (not exceeding 0.2mm) and barrel wear
(3) Maintain and polish the mold every 100,000 cycles
(4) Calibrate temperature sensors and pressure sensors quarterly
(5) Establish equipment files, record maintenance and repair history
(6) And strengthen process monitoring; on the original basis, additional attention is needed, paying special attention to parameter stability
Conclusión clave
Equipment maintenance is the basis of stable production, and a standardized regular maintenance system and record system needs to be established.
Targeted preventive measures need to be taken in different production scenarios.
