What causes poor cooling of 50kW generator?

1. If there is poor cooling in the 50kw generator, it is very likely that your unit's cooling system has not been cleaned in a long time. Under normal circumstances, the water tank should be cleaned after the unit is completed. has been used for six months or after a cumulative working time of 500 hours. Failure to clean the scale within this time frame may result in poor cooling of your device.

2. If the performance of the diesel generator set fan is poor, such as the fan installation is not firm, the blades are loose, cracked, deformed, etc., it may cause the dissipation performance to be reduced. thermal of the unit, thus causing poor cooling of the diesel generator set.

3. In addition, if

the impeller of the water pump of the 50kw generator set is damaged or the gap between the impellerand the hull is too large, this will cause insufficient circulation. water in the cooling system, causing the water temperature to be too high, resulting in poor cooling of the unit.

4. Dirty cooling water from the diesel generator set will also cause poor cooling of the unit. The cooling water for the unit should not be clean, soft water containing mineral salts such as calcium and magnesium. If conditions are limited, only hard water should be softened before use.

5. Additionally, a lack of cooling water in the radiator is also a cause of poor cooling of the unit. Therefore, during daily use of the unit, frequent inspections and timely replenishment should be carried out. the liquid level will be too low, which will affect the cooling effect of the unit, worsening the cavitation of thediesel engine. If added every day, check for water leaks in the cooling system.

): A. Water quality requirements

Be sure to use clean water that meets the requirements of ASTM D4985. If it does not meet this requirement, the cooling system may fail, resulting in a reduction in cooling effect. If the water quality does not meet these requirements, distilled water or coolant should be used. Total

Never use water alone. The efficiency of the coolant will decrease after a while. Therefore, the coolant must be replaced. As long as you follow FDI Kang's coolant recommendations, you can adopt the following replacement cycle. Coolant Change Intervals Coolant (glycol mixture) and coolant filterchange every 4 years or at least every 10,000 hours Coolant (glycol mixture) without cooling filter Every year or at least every 5,000 hours Anti-corrosion agent Every year a. The cooling system must be flushed. When replacing the coolant, do not replace the coolant filter (accessory). The coolant filter should be replaced 6 months after the first coolant replacement, then every 6 months. b. If there is a risk of freezing, use a mixture of 50% antifreeze and 50% pure water. Mix the glycol and water in a separate container before adding the mixture to the system; there is never any risk of frost. Use a mixture of water and preservative as a coolant. The mixing ratio is 1:30. After adding the coolant, allow the engine to run at operating temperature, which can maximizeer the effectiveness of the additive. If the annual operating time exceeds 500 hours, 1/2 liter of anti-corrosion agent should be added to the coolant every 500 hours. However, regardless of climate, we recommend using a coolant mixture of ethylene glycol and purified water year-round. c. Except in an emergency, do not open the water filler cap while the engine temperature is still very high. Otherwise, steam may escape. Check the coolant level daily before starting the engine and add more if necessary. The coolant level should be 5 cm lower than the sealing surface of the water filler cover. If a split expansion tank is installed, add between the MIN and MAX marks. Notice! When adding, use the same coolant as the original coolant in the system.coldness. Notice! Never mix antifreeze (ethylene glycol) and corrosion inhibitors. Mixing these two substances will create foam and significantly reduce the effectiveness of the coolant. Notice! Refill the drained cooling system with coolant. Notice! Additives are harmful to the human body, please pay attention to safety when handling.
