Maintain plastic processing equipment in sections

Plastic processing equipment needs maintenance. Through maintenance, the aging speed of the parts and components of the equipment can be effectively slowed down, and the service life of the equipment can also be increased. It can be said that the benefits are very many. Plastic processing equipment needs weekly maintenance. However, in order to reduce your workload, the equipment can also be divided into weekly, monthly and annual intervals for maintenance. This not only protects the plastic processing equipment, but also reduces your workload.

I. Check the maintenance items weekly

1. Check and tighten the connecting bolts, such as the bending elbow connection and the fastening bolts of the moving parts, the fastening bolts or screws of the movable parts in the mold and its structure, the locking screws fixed by the limit switch, etc.
2. Check the cooling pipes and oil routes of each system in the cooling device of hydraulic oil and lubricating oil of plastic processing equipment, check whether there is oil and water leakage phenomenon, and properly tighten or replace the sealing gasket when necessary.

II. Monthly check and maintenance items

1. check the quality of hydraulic oil, found that the oil contains impurities, oil amount is insufficient or contains water should be processed in time. Insufficient hydraulic oil is added.

2.Check whether the line of each point device is loose.

3. Check the ventilation filter on the electric control box of plastic processing equipment，to remove dirt and remove it for cleaning if necessary.

III. Check the maintenance items every year

1. Check the quality of hydraulic oil, clean the control valves, pipelines and fuel tanks in the hydraulic system of plastic processing equipment, and replace the hydraulic oil.
2. Check the mechanical transmission deceleration system of plastic processing equipment, such as the cleaning of bearings, check the wear condition, and replace the bearings if necessary. Check the wear condition of gear tooth surface and the quality of lubricating oil in reduction box. Keep records.
3. Check the wear condition of screw and barrel of plastic processing equipment, repair the slight wear and scratch, repair when the wear is more serious, record well and propose replacement plan.
4. Each drive motor, hydraulic pump, motor should be disassembled and checked, check the wear of plastic processing equipment bearing, pump body and other places, add lubricating oil (grease) after cleaning, record the wear parts, and put forward the maintenance or replacement of new parts.
5. Check the sealing ring and wearing parts of plastic processing equipment and replace them if necessary.
