The cooling system of
diesel generator set is the key to its stable operation. Malfunctions may cause the body to overheat, leak water, or make abnormal noises, affecting performance and lifespan. The following is a simplified guide for fault diagnosis and maintenance:
1. Common faults and causes
High body temperature: may be caused by water leakage, insufficient cooling water, loose fan belt, worn water pump, long-term overload, late fuel injection, thermostat failure, etc.
Cooling water leakage: radiator leakage, water pipe rupture, loose drain switch, damaged water seal, etc.
Abnormal noise: Fan blades hitting radiator, loose belt hub, etc.
2. Fault diagnosis methods
Appearance inspection: Check for water leakage, water level in the tank, fan belt, blades, etc.
Performance testing: Use instruments to detect the temperature and pressure of the cooling system.
Disassembly and inspection: For difficult to determine faults, disassemble and inspect the water pump, thermostat, etc.
3. Maintenance Guide
Supplement cooling water: Timely replenish water and repair the leakage point.
Adjust or replace the belt: Adjust the tension or replace the worn belt.
Cleaning the radiator: Regularly clean the accumulated dirt to maintain smooth heat dissipation.
Replace damaged components such as fan blades, water pump, thermostat, etc.
Adjust fuel injection time: Ensure that the fuel is fully burned.
Daily maintenance: Regularly check the quality of the coolant, replace the coolant, and clean the radiator.
summarize
The fault diagnosis and maintenance of the cooling system of diesel generator sets require a comprehensive inspection of appearance, performance, and disassembly. During maintenance, follow the operating procedures to ensure quality. Strengthen daily maintenance, prevent malfunctions, and extend equipment lifespan. It is recommended to develop a detailed maintenance plan based on the equipment model and usage environment to improve the ability of operators.
