The service life of solid waste treatment equipment depends not only on materials and manufacturing processes, but also on scientific and standardized maintenance management. Clear maintenance milestones and standardized maintenance procedures can effectively slow equipment aging, reduce failures and maintain long-term stable operation. Henan Yongle Group has established a complete standardized maintenance system for plastic refining equipment, dividing maintenance content into stages to facilitate equipment life management and daily maintenance for users.

The maintenance content of the plastic refining equipment is divided into stages according to operating hours, comprising three levels: daily inspection, periodic maintenance and annual overhaul. The maintenance focus of each level is clear and well defined, covering circuits, pipelines, the furnace body, the purification system, transmission components and all other structures, achieving all-round equipment maintenance.

Daily inspection focuses on condition monitoring. Workers can check equipment temperature, pressure, sealing status and the operation of purification equipment against standard ledgers, promptly detecting minor operating abnormalities for early intervention and preventing small problems from accumulating and affecting overall production.

Periodic maintenance involves regular inspection and replacement of wearing parts, filter consumables, sealing components and other loss-prone parts, keeping all equipment units up to standard. Regular maintenance maintains stable equipment conditions and avoids chain equipment problems caused by part aging.

The annual overhaul focuses on the inspection of the equipment's core structures, including furnace body integrity, pipeline patency, electrical control system accuracy and anti-corrosion coating condition. Through comprehensive inspection and repair of worn parts, equipment performance is kept within the initial operating range, extending the overall service life of the equipment.

The standardized maintenance management system gives the later-stage maintenance of plastic refining equipment clear rules to follow, reducing arbitrariness and uncertainty in equipment operation. The scientific maintenance model and comprehensive maintenance content support long-term, stable and low-failure normalized operation of waste plastic resource recovery projects.
