I. Preventive Maintenance Measures
1. Regular Inspection and Maintenance
Daily: Check the engine oil level, hydraulic oil cleanliness, tire pressure (tolerance ≤ ±0.2 bar), and any adhesion on the roller surface.
Every 500 hours: Replace the hydraulic oil filter (ISO VG46 anti-wear hydraulic oil is recommended) and clean the radiator.
Seasonal Maintenance: Replace low-temperature engine oil (-20°C diesel) in winter and check the electrical system for water resistance during the rainy season.
2. Wear Parts Management
Lubricate the vibration bearing with lithium-based grease (NLGI Grade 2) every 2000 hours. Replace if wear exceeds 1mm.
Check belt tension monthly; adjust if deflection exceeds 15mm.
II. Optimizing Operating Procedures
1. Standardized Operating Procedures
After starting, run the machine at no load for 3-5 minutes. Observe the instrument panel for any abnormal alarms (if the hydraulic oil temperature exceeds 80°C, the machine should be shut down for inspection). Maintain a constant speed during compaction (1.5-2 km/h for initial compaction, 2-3 km/h for secondary compaction) to avoid excessive drive shaft torque due to sharp turns.
2. Environmental Adaptation
On soft ground, perform static compaction 1-2 times before activating vibration mode to prevent clutch damage.
In high-temperature environments, install a fuel preheater to prevent wax buildup on the injectors.
III. Technology Upgrade and Monitoring
1. Intelligent Monitoring System
Install a compaction sensor to monitor the compaction trajectory and density in real time (automatic alarm if deviation >5%).
Use a digital work order system to record fault codes and repair history, optimizing maintenance intervals.
2. Hydraulic System Optimization
Use a load-sensing hydraulic system and regularly check for leaks (a leak rate of <5 drops/minute is acceptable).
IV. Personnel Training and Management
1. Operator Training
Operators must obtain certification and receive refresher training every two years, focusing on understanding the principles of the hydraulic system, vibration mechanism, and emergency response. Analyze common failure modes (such as clutch overheating and vibration failure) through FMEA and develop preventive measures.
2. Full Employee Participation in TPM
Operators perform basic daily inspections (such as oil line sealing and brake sensitivity) and incorporate them into performance evaluations.
