Gas Internal Combustion Engine: A Daily Maintenance Guide for Enterprises
Key to Extended Lifespan & Stable Operation!
As the core equipment for power generation and energy supply in industrial operations, the gas internal combustion engine’s daily maintenance directly affects its operational efficiency, service life, and safety. Proper maintenance not only reduces breakdowns and downtime but also lowers overall operation and maintenance (O&M) costs. Below are the key points for daily maintenance of gas internal combustion engines:
1. Daily Inspections and Basic Maintenance
Visual and Connection Inspection:
Check the engine for any signs of oil, gas, or coolant leakage. Inspect the connections of the gas pipeline, water lines, and oil lines for looseness or damage.
Fluid Levels and Pressure Check:
Ensure engine oil level and coolant level are within standard operating ranges. Check the gas pressure, cooling water pressure, and lubrication oil pressure to prevent abnormal pressure conditions that could cause component wear.
Operational Parameter Monitoring:
Record key engine parameters such as engine speed, exhaust temperature, water temperature, and oil temperature. Compare with historical data; if abnormal fluctuations are observed (e.g., sudden rise in exhaust temperature), stop the engine for immediate troubleshooting.
Cleaning Tasks:
Clean surface dust and oil stains on the unit. Maintain cleanliness of the radiator fins and air/gas filters to prevent clogging and ensure efficient cooling and air intake.
2. Scheduled Core Component Maintenance
Fuel/Gas System
Inspect the gas filter weekly; replace the filter element periodically (usually every 1–3 months, depending on usage) to prevent impurities from clogging injectors.
Monthly check the sealing condition of gas valves and pressure regulators to ensure no leakage. Calibrate gas flow sensors to ensure stable fuel supply.
Lubrication System
Replace engine oil regularly as per the user manual (typically every 200–500 hours or based on oil quality analysis). Also replace the oil filter to avoid engine wear caused by contaminants in old oil.
Check the oil pump pressure to ensure the lubrication system operates within normal pressure range, preventing wear of key components such as pistons and crankshaft.
Cooling System
Check coolant concentration weekly (for antifreeze and anti-corrosion performance). Refill with the same type of coolant when levels are low to avoid mixing incompatible fluids.
Clean the radiator and coolant tank every 3–6 months to remove scale and impurities, ensuring effective heat dissipation and preventing engine overheating.
Inspect the tension and wear of the water pump and fan belts; adjust or replace if belts are loose or cracked.
Ignition System
Every 500–1000 hours, inspect spark plugs (or ignition electrodes) for wear and carbon deposits. Clean or replace if necessary to ensure reliable ignition.
Check the insulation condition of ignition coils and high-voltage wires to avoid energy loss and maintain ignition efficiency.
3. Quarterly and Annual Deep Maintenance
Valve and Piston Components:
Inspect valve clearance every 1000–2000 hours and adjust if necessary. Check piston ring sealing to prevent gas leakage and efficiency loss.
Sensors and Control System:
Calibrate temperature, pressure, and speed sensors quarterly to ensure accurate data. Check the condition of control modules and update firmware or software if required.
Safety System Testing:
Conduct annual tests on emergency shutdown, overload protection, and gas leak alarm systems to ensure timely response during failures.
Comprehensive Disassembly Inspection:
Based on the engine's operational life (typically 3–5 years), perform a full disassembly to inspect components such as the cylinder block, crankshaft, and bearings, and replace aging parts as needed.
4. Maintenance Records and Emergency Preparedness
Maintain a detailed maintenance log that records the date, maintenance content, replaced parts, and key operating parameters from each session. This facilitates traceability and forecasting of the next maintenance schedule.
Keep a stock of commonly used wear parts (e.g., filters, spark plugs, belts) to minimize downtime caused by part shortages during repairs.
Provide regular training for operation and maintenance personnel to ensure they understand proper procedures and emergency handling skills.
Proper daily maintenance of gas internal combustion engines relies on consistency, standardization, and attention to detail. Through scientific and timely upkeep, the equipment can maintain optimal performance while minimizing failure risks and repair costs.
