Plastic machinery in action, to the plastic machinery for maintenance, and this maintenance and maintenance must be in accordance with certain provisions to operate, so conducive to the operation of machinery and equipment, at the same time according to the corresponding equipment safety technical performance related requirements to maintain, can effectively guarantee the maximum safety equipment and personnel. Pre-loading inspection equipment is also composed of various parts, before installation, for each equipment parts inspection, check the main steel structure, bearings, bolts, etc. on the situation, at the same time for the surface of the parts is anti-corrosion, etc., this should be a record for later inspection. Maintenance and the normal operation of the equipment, according to the rules and regulations to carry out the day-to-day and regular maintenance, daily maintenance is mainly responsible for cleaning, fastening, lubrication, adjustment, anti-corrosion, this is to be checked every day, and regular maintenance, in the prescribed time for mechanical equipment maintenance and repair, to clean, lubrication, adjustment , disintegration, overhaul as the central content. Overhaul requirements and equipment overhaul, it means that the damage of this equipment is very serious or damaged very serious, mechanical performance significantly decreased, this time is the overhaul, such as the mechanical performance of a significant decline in fuel consumption, operation, sound anomalies or equipment can not play normal production performance conditions, A comprehensive and thorough method of restorative repair, this time, should be carried out in accordance with the provisions of the overhaul, and the schedule of work. Equipment scrapped in the process of overhaul, there will be scrap possible, by the maintenance professionals responsible for implementation, to have records, have acceptance. For more than and near the end-of-life of equipment installation shoul.
