The Diesel Generator Set generates a large amount of heat during operation. If the ventilation and heat dissipation are poor, it can cause the unit temperature to be too high, affecting performance, shortening usage time, and even causing malfunctions. The following are key considerations for ventilation and heat dissipation, covering design, installation, maintenance, and emergency response.
1、 Design requirements for Diesel Generator Set ventilation system
Independent intake and exhaust
The air inlet and exhaust outlet should be completely isolated to avoid hot air backflow.
Material and structure of air duct
Recommended materials: galvanized steel sheet, stainless steel or flame-retardant composite material.
2、 Diesel Generator Set Installation and Layout Specification
Unit spacing
The units installed in parallel should maintain a distance of ≥ 1.5 meters between each other to ensure air circulation.
Environmental requirements
Altitude: If the altitude exceeds 1000 meters, the power operation needs to be reduced (1% reduction for every 100 meters increase).
Temperature: The temperature in the computer room should be controlled between 5 ℃ -40 ℃, and the humidity should be ≤ 85% (without condensation).
Inlet air filtration
Install an air filter (efficiency ≥ F7 level), regularly clean or replace the filter element, and prevent dust from clogging the radiator.
3、 Maintenance points for Diesel Generator Set radiator
Daily inspection
Appearance: Check if the radiator is deformed, blocked, or leaking. Cleaning: Clean the radiator fins with compressed air every month.
Coolant management
Replacement cycle: Replace every 2 years or 4000 hours to avoid mixing different brands of coolant.
Fan and belt
Belt tension: Press the middle of the belt with your thumb and let it sink 10-15mm. Fan speed: Ensure that the fan speed matches the unit load to avoid insufficient heat dissipation during low-speed operation.
4、 Diesel Generator Set Operation Monitoring and Emergency Response
temperature monitoring
Key parameters:
Coolant temperature: ≤ 95 ℃. Exhaust temperature: ≤ 650 ℃.
Tool: Install a temperature sensor and connect it to the monitoring system to provide real-time prompts.
Emergency measures for high temperature
Immediate load reduction: When the temperature exceeds the alarm value, reduce the load to below 50%. Check ventilation: Confirm if the fan is functioning properly and if the air duct is blocked. Emergency stop: If the temperature continues to rise, stop the machine immediately for inspection.
5、 Diesel Generator Set Maintenance Record and Spare Parts Management
Maintain records
Record the time and results of each cleaning of the radiator, replacement of coolant, and inspection of the belt. Establish temperature monitoring logs and analyze the causes of abnormal fluctuations.
Spare parts reserve
Reserve key spare parts: air filter, coolant, belt, temperature sensor. Regularly check the validity period of spare parts to ensure they are always available.
By scientifically designing ventilation systems, standardizing installation layouts, and strictly maintaining management, the heat dissipation requirements of Diesel Generator Sets can be effectively guaranteed, extending equipment usage time and improving operational reliability.
