What do diesel generator radiators need to pay attention to in operation?
June 23, 2022
Radiator is one of the important components indispensable in the configuration of diesel generator sets, it is vital to ensure the operation of the unit, but the equipment is always inevitable failure, the most common is the radiator overflow phenomenon, in order to avoid radiator failure, the user in the diesel generator set radiator operation process to pay attention to some issues.
Radiator is one of the important components indispensable in the configuration of diesel generator sets, diesel generator sets in operation will produce high temperature, in order to ensure that the unit and parts will not be deformed and damaged because of high temperature, we need to carry out cooling work, the role of the radiator is to ensure that the temperature of the generator set will not be too high, it is vital to protect the operation of the unit, but the equipment is always inevitable failures, the most common is Radiator overflow phenomenon.
Diesel generator set radiator overflow may occur because the injector water seal sleeve is not tightly sealed or cracked. Injector and cylinder head in the middle of the water sleeve. Waterproof sleeve and waterway coupling, and sealed with a rubber seal. After long-term operation, the cylinder head water sleeve and the cylinder head connection will produce tiny cracks because of aging, or because the rubber is old and poorly sealed. The mixture after combustion seeps into the waterway through tiny gaps, causing the water in the radiator to spill.
In order to avoid radiator failure, the user should pay attention to the following issues during the operation of the diesel generator set radiator.
1, running generator set radiator coolant is usually very hot, and is under pressure, not in the uncooled radiator finishing or remove the tube, do not work on the radiator while the fan is turning or open the fan protection cover.
2. Prevent corrosion problems. Always keep the tube joints from leaking, and regularly add water from the top of the radiator to discharge air to keep the system "air-free". Radiator should not be in a partial injection of water, because this will accelerate corrosion. For non-working generators, empty or fill the water completely. If possible, use distilled water or natural soft water, and add the right amount of rust inhibitor.
3, external cleaning. In an environment with much dust or dirt accumulation, the radiator gaps may be blocked by debris, insects and other things, thus affecting the efficiency of the radiator. Regular cleaning of these light deposits can be done with low-pressure hot water plus cleaning agent spray wash, the steam or water from the front of the radiator to the fan jet. Spraying from the opposite direction will only blow the dirt into the center. When using this method, use a cloth to cover the diesel engine and alternator. Stubborn deposits, and can not be removed by the above method, then the radiator can be removed and dipped in hot alkaline water for about 20 minutes, and then rinsed clean with hot water.
4, internal cleaning. If because of the joint leakage, there is no choice but to use hard water irrigation method used for a period of time, or because of power generation run for a period of time and no rust remover, the system may be clogged by scale.
