The Yuchai diesel generator needs to pay attention to the following matters in terms of ventilation and heat dissipation to ensure the normal operation of the unit and extend its service life. I hope the following introduction can provide users with reference.
1、 Ventilation Design of Yuchai Diesel Generator
Site selection and layout of computer room
The Yuchai diesel generator should be installed in a well ventilated, clean environment, and near the main electrical equipment and distribution room in the machine room. The computer room should be equipped with exhaust facilities to ensure air circulation. If necessary, a fan can be installed for forced ventilation in the machine room of an open diesel generator set.
Setting of air inlet and exhaust outlet
Air inlet: It is recommended that the total area of the air inlet should be at least twice the area of the unit's radiator to ensure that the unit receives sufficient air during combustion and cooling processes. The air inlet should be equipped with louvers or grids to prevent rainwater from entering, and should be located directly facing the generator end or on both sides of the generator end. In cold climate regions, adjustable louvers can be installed at the air inlet of standby and low operating frequency generator sets to close when the unit stops.
Exhaust port: The area of the exhaust port should be 1.5 times the exhaust area of the radiator to ensure timely discharge of hot air. The exhaust fan should be installed at an inner high position to timely discharge the high-temperature rising airflow outside. The exhaust outlet should also be equipped with louvers or grids, and avoid being located on the dominant wind direction side to reduce wind resistance.
Air duct design
If there is no air duct, it is recommended that the distance between the radiator and the exhaust outlet be controlled within 150 millimeters.
Suitable bends should be used for the bending of air ducts to reduce air resistance. If the pipeline is too long, the diameter needs to be increased to reduce the exhaust back pressure.
2、 Heat dissipation measures for Yuchai diesel generator
Check the cooling system
Regularly inspect the cooling system of the Yuchai diesel generator to ensure that the cooling water circuit is unobstructed. The heat sink should be kept clean and free from blockage or damage. If the heat sink has rusted due to prolonged use, it should be replaced promptly to prevent leakage and poor coolant circulation.
Check if the water pump is functioning properly. Check if the coolant level of the Yuchai diesel generator is too low or not in compliance with regulations. The coolant should be prepared according to the specified ratio to ensure its circulation and anti-corrosion performance.
Increase air cooling effect
For generator sets with high power or heavy loads, increasing the air cooling effect can be considered
Avoid overloading operation
Try to control the diesel generator set from operating at overload as much as possible
3、 Other precautions for Yuchai diesel generator
Dust and moisture prevention
The Yuchai diesel generator room should be kept clean to prevent dust from entering the generator set and affecting the insulation performance between the engine rotors.
Regular inspection and maintenance
Regularly check the working status of the ventilation and heat dissipation system, including the integrity and operational efficiency of components such as fans, air ducts, and louvers. Timely clean dust and debris to ensure smooth operation of the system.
Regularly maintain the generator set, including changing the engine oil, cleaning the air filter, checking the battery, etc
Safety protection, install fire extinguishing devices in the computer room
There are multiple aspects to consider when it comes to ventilation and heat dissipation for Yuchai diesel generators. Through reasonable site selection and layout of the computer room, scientific setting of air inlet and outlet, effective heat dissipation measures, and regular inspection and maintenance, the generator set can be ensured to operate stably in good condition and extend its service life.
