Primary maintenance is mainly carried out by the operator with the assistance of the maintenance staff. According to the instructions of the extrusion machine equipment manufacturer, the equipment shall be partially disassembled and inspected, the specified parts shall be cleaned, the oil and pipeline shall be dredged, the fit clearance of each part of the equipment shall be adjusted, and each part of the equipment shall be fastened.According to the statistics of the extrusion machine equipment manufacturer, the maintenance time is about 4~8 hours.Its main purpose is to reduce equipment wear, eliminate risks and extend the service life of equipment.Guarantee the equipment for the completion of production tasks before the next warranty period.
Extrusion machine manufacturer: The screw extrusion system consists of daily maintenance and regular maintenance.
How do Shenghai Aluminum usually maintain the machines?
(1) Routine maintenance is a kind of routine maintenance, which does not occupy the running time of the equipment and is usually completed when the power is on.Clean machine, lubricate moving parts, tighten loose screws, timely check and adjust motor, control instrument, and all moving parts and pipes.
(2) Routine maintenance is usually stopped after 2500-5000 hours of extrusion machine operation.The machine needs to be disassembled for inspection and spare parts.
(3) Extrusion machine manufacturers do not allow idling to avoid thread rolling and tube wool.
(4) If there is abnormal sound during the operation of the extruder, it should be stopped for maintenance immediately.
(5) Extrusion machine manufacturers remind, strictly prevent metal and other waste into the funnel, so as not to screw and drum damage.In order to prevent the scrap iron from entering the cylinder, magnetic adsorbent or magnet support must be installed at the place where the material enters the liquid feed port of the cylinder to prevent the scrap iron from falling off, and the material is screened in advance.
(6) Pay attention to the cleanliness of the production environment, avoid waste impurities mixed into the material to block the filter plate, affect the product output, improve product quality and nozzle resistance.
(7) When you need to stop using the extrusion machine for a long time, please apply anti-rust grease on the screw, cylinder, nozzle and other working surfaces.Small screws should be suspended in the air or placed in a special wooden box, and the sawdust should be placed flat to avoid deformation or damage of the screws.
(8) Thermometers should be calibrated periodically to check the correctness of the adjustment and the sensitivity of the control.
(9) The maintenance of extrusion machine reducer is the same as that of general standard reducer.Extrusion equipment manufacturers suggest that the main inspection gear, bearings and other wear and failure.Reducer must use the lubricating oil specified in the machine manual, and according to the specified oil level.If the oil is too little, insufficient lubrication, will reduce the service life of the parts.
Too much oil, high heat, high energy consumption, oil deterioration, will also lead to lubrication failure, damage parts.In order to ensure the amount of lubricating oil, the extrusion equipment manufacturer reminds the oil leakage part of the reducer to be replaced immediately
