FAQ

How to Prevent Premature Wear of Active Components in Diesel Generators

Key technical measures to prevent premature wear of active components (e.g., journals and bearings, piston pins and bushings, piston rings and cylinder walls) in diesel generators:

1.Optimize Lubrication

• Ensure proper lubrication of friction surfaces by selecting lubricants according to the generator’s specifications and ambient temperature.
• Maintain oil pressure and outlet temperature within manufacturer-recommended ranges.
• Regularly check and replenish oil levels during operation.
• Keep oil storage, refilling, and replacement processes clean.

2. Proper Installation and Maintenance

• Follow the user manual to ensure correct clearances during assembly (e.g., main/connecting rod bearing clearances, piston pin-to-bushing clearance, piston ring-to-cylinder clearance).
• Periodically inspect and adjust clearances during operation.

3.Eliminate "Three Leaks" (Oil, Water, Air)

• Promptly address oil, water, or air leaks. If light yellow foam appears in the lubricant (indicating water ingress), shut down the generator immediately.
• Investigate and resolve leaks before resuming operation.

4.Surface Quality and Hardness Control

• Ensure friction surfaces meet required roughness standards (smoother is better).
• Maximize journal hardness.
• The hardness of piston rings (except the top ring) should be slightly lower than that of the cylinder walls.

5.Optimize Combustion Parameters

Verify cylinder compression ratios, fuel injection volume, timing, and combustion pressure to ensure uniform cylinder firing and reduce bearing surface load.

6.Routine Maintenance and Monitoring

• Conduct daily inspections using monitoring instruments.
• Listen for abnormal noises, monitor component temperatures, and keep the generator clean.
• Maintain detailed operation logs.
• Establish a lubricant replacement schedule based on operating conditions to balance cost and performance.
• Clean the lubricating oil filter weekly and the oil cooler every 3,500 hours of operation.
• During maintenance, prevent debris from entering the generator and coat exposed friction surfaces with protective oil.
