I. Real-time Monitoring and Acquisition of Core Parameters Continuously collect data on main motor current, vibration, and temperature to capture abnormal fluctuation signals. Regu

I. Prevention of Failures in the Main Motor and Transmission System 1. Record the main motor's current, vibration value, and temperature rise curve daily. Immediately stop the

1. Main Motor and Transmission System Common Faults: Unstable main motor current fluctuations, motor failure to start, excessive bearing temperature rise, abnormal gearbox noise. C

I. Defining the Core Principles of the Maintenance Plan 1. Focus on preventative maintenance, replacing the traditional post-failure repair approach, to reduce unexpected downtime

I. Reducing Unplanned Downtime from the Root Cause 1. Routine Preventive Maintenance: Clean guide rails and sensors weekly, check wiring terminals monthly for looseness, replenish

I. Precise Optimization of Process Parameters 1. Segmented Gradient Temperature Control: Abandoning the constant temperature mode across the entire range, the feeding section uses

I. Basic Parameter Matching Verification 1. Length-to-Diameter Ratio: 25-30 for conventional PPR extrusion, 28-32 for high-temperature PEEK processing, and 36-44 for high-filler wo

1. Material and Process Compatibility Verification: Confirm that the screw structure is compatible with the PPR, PEEK, wood-plastic composites, and other materials you process; tha

I. Core Operational Stability Testing 1. Extrusion Output Stability Testing Run continuously at full load for 8-12 hours, weighing the extruded molten material at fixed intervals.
