1. Before each startup, check the power supply, vacuum system, air pressure system and cooling system. After the equipment is started, check whether the rotation direction of each rotating part is correct. Pay attention to the lubrication of each lubricating part. The electrical instruments shall be maintained according to the regulations.
2. Special personnel shall be assigned to operate the equipment. It is not allowed to idle the extruder screw without material to avoid scratching the screw and the barrel. After shutdown, if there is material stored in the barrel, before starting the machine again, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements, and the machine can be started after holding for more than 30 minutes. It is strictly prohibited to start the machine before the temperature reaches the requirements, so as to avoid damage to the machine parts.
3. When feeding the hopper, it must be kept clean and prevent metal sundries, sand and small tools from entering the feeding port to prevent damage to the barrel and screw. If abnormal noise is found during operation, it should be stopped immediately for treatment.
4. If the screw is taken out of the barrel for some reason, it should be properly handled to prevent deformation. If it is not installed in the barrel for a long time, the screw must be hung vertically to prevent damage, bending and permanent deformation. The surface of the barrel and the screw shall be coated with anti rust oil for protection.
5. The use, adjustment, maintenance and maintenance of temperature controller, electronic instrument and electrical switch shall be carried out in accordance with the procedures and product instructions.
6. In addition to routine maintenance, regular maintenance shall be carried out. The die head shall be thoroughly cleaned every three months, the lubricating grease of various bearings shall be replaced every three months, the lubricating oil of the reducer shall be replaced every six months, and the overall equipment shall be overhauled every two years.
Note: before operating the equipment, read the instruction manual in detail to understand the control and regulation functions; Heighten vigilance and pay attention to safety; Pay attention to safety signs; Wear appropriate eye protection; Wear appropriate protective clothing; Proper use of maintenance tools; Do not directly touch the high-temperature working or heating equipment, and pay attention to the scald caused by the overflow of high-temperature melt; Pay attention to scratches on precise parts; Carry out proper maintenance of equipment; The wire and power parameters used shall meet the requirements
It is absolutely forbidden to turn on the power during the maintenance of the circuit; It is absolutely prohibited to extend limbs into parts that may cause harm to human body such as equipment transmission; After equipment maintenance, equipment protection facilities shall be returned in time; Before connecting the power supply, confirm that the equipment is well grounded.
