First, the bearings of the expanded case body should be filled with lubricating grease in time. After 500 hours of operation, all the lubricating grease should be replaced once. (A suitable amount of grease should be added before the operation of the new machine, and the oil should be changed after 200 hours of operation.)
Second, other bearing parts should be filled with grease regularly.
Third, it is strictly forbidden to use hard objects and heavy hammers in the process of disassembly and assembly of vulnerable parts such as screws and screw sleeves, and it is strictly prohibited to place heavy objects or stand people on the expansion cavity of the extruder.
Fourth, the puffed raw materials should be cleaned to prevent foreign objects such as metals from entering the machine and damaging the parts.
Fifth, check the quality of the extruder at any time and pay attention to replacing the wearing parts.
Sixth, keep the area around the equipment clean.
Seventh, when shutting down for a long time without using or replacing the puffed materials, the materials in the puffing cavity should be removed to avoid agglomeration, mildew or cross-contamination between materials.
Eighth, because the wearing parts near the discharge port wear relatively quickly, the wearing parts near the feed port are less worn. Therefore, when replacing the wearing parts, the extruder should be replaced sequentially from the discharge end. It is not suitable Replace multiple parts at once.
