Maintenance and maintenance of the extruder
The screw extrusion system adopts daily maintenance and periodic maintenance for maintenance.
(1) Daily maintenance It is a regular routine work. It does not account for the operating hours of the equipment. It is usually completed during the driving period. The focus is to clean the machine, lubricate the moving parts, tighten the loose threaded parts, check in time, adjust the motor, control the instrument, and each work piece. Components and pipelines, etc.
(2) Regular maintenance is generally performed after the extruder has been continuously operated for 2500-5000 hours. The machine needs to be disassembled for inspection, measurement, and identification of the wear and tear of the main components. Replacement has been completed Parts that have reached the specified wear limit. Repair damaged parts.
(3) It is not allowed to run empty to avoid roughening of the screw and the machine shaft.
(4) Operation of the extruder If abnormal noise occurs, stop the machine immediately for inspection or repair.
(5) Be careful to prevent metal or other debris from falling into the hopper to avoid damaging the screw and barrel. To prevent iron Debris enters the barrel. You can install magnetic components or a magnetic frame at the feeding port where the material enters the barrel. To prevent debris from falling in, the material must be screened in advance.
(6) Pay attention to the cleanliness of the production environment. Do not allow garbage impurities to be mixed into the material and block the filter plate, which will affect the product output and quality and increase the resistance of the machine head.
(7) When the extruder needs to be stopped for a long time, the screw and machine should be installed. The working surfaces such as the machine head should be coated with anti-rust grease. Small screws should be suspended in the air or placed in a special wooden box and leveled with wooden blocks to prevent the screw from deforming or being bruised.
