On time Routine maintenance and periodic maintenance are implemented for mechanical maintenance, strictly in accordance with the cycle and inspection and maintenance items specified in the instruction manual.
1.0n time Routine maintenance is the cleaning and inspection carried out before, during and after the operation of the machine. It mainly checks the condition of key and vulnerable parts(such as mechanical safety devices), coolant, lubricant, fuel quantity, instrument indication, etc.
2.First-level maintenance: generally carry out cleaning,tightening and lubrication operations, and carry out partial adjustment operations to maintain the technical condition of the machinery intact.
3.Secondary maintenance: including all contents of primary maintenance,with inspection and adjustment as the center, to maintain the good working performance of the mechanical assemblies,mechanisms and parts.
4.Seasonal maintenance: The main content is to replace the lubricating oil and fuel oil suitable for the season, take antifreeze measures, and increase antifreeze facilities.
5.Maintenance during the running-in period: After the running-in period of the new machine and overhauled machinery is completed, the running-in period must be maintained. The main contents are cleaning,tightening, adjusting and replacing the lubricant.
6.Transferment maintenance: The transfer and maintenance should be carried out before the machine is transferred to the construction site. The operation content can be maintained according to the technical status of the machine, and if necessary, anti-corrosion can be carried out.
7.Disable maintenance:The decommissioning and storage machinery should be maintained, mainly for cleaning,anti-corrosion and moisture-proof.
