The maintenance techniques for TBM (Tunnel Boring Machine) brushes mainly include the following aspects:
The key technology of maintenance management system: The maintenance management system of TBM equipment is the key to ensuring the normal operation and extending the service life of the equipment. The system includes preventive maintenance and repair, which can greatly reduce the occurrence of equipment failures and enhance understanding of the equipment through regular inspections and maintenance
Daily preventive maintenance: Daily preventive maintenance is an important means of solving potential problems. This includes regularly checking the oil level and temperature of the hydraulic and lubrication systems to ensure that the equipment is operating at its optimal condition. There are detailed regulations on the type, grade, brand, and frequency of use of lubricants to ensure that all components of the equipment receive appropriate lubrication
Routine inspection for each shift: The routine inspection for each shift includes checking the oil level and temperature of the hydraulic oil tank to ensure that the oil level is close to the upper limit scale and the oil temperature is within the normal range. In addition, it is necessary to check the torque and oil temperature of the cutterhead to ensure that the equipment is operating normally
Condition monitoring and oil sample analysis: By using online monitoring devices and data acquisition systems, combined with offline vibration analysis and oil sample detection, the operating status of the equipment can be accurately diagnosed. Oil sample analysis can help identify wear particles in lubricating oil and hydraulic oil, thereby determining the wear condition of equipment
Maintenance principle and accessory management: The maintenance principle emphasizes rapid maintenance, comprehensive analysis of the cause of the fault based on monitoring information, determination of the maintenance plan, and implementation in the shortest possible time. Accessory management requires strengthening maintenance concepts, adhering to cleaning principles, and ensuring the cleanliness and lubrication of all components of the equipment
