The diesel generator set will generate a lot of heat during its normal operation, and the oil has the function of partial heat, while the oil is affected by high temperature. If the oil temperature exceeds 120 ° C for a long time, it will lose its function of lubrication, cleaning and heat dissipation. In serious cases, it will directly cause the engine to burn and hold the shaft, so the diesel engine oil radiator of the diesel generator set is required to play a role to keep the oil working within the appropriate temperature range, Forced cooling of the oil at high temperatures.
The oil radiator of diesel generator set is a device to accelerate the heat dissipation of lubricating oil and keep it at a low temperature. On high performance and high power intensified engines, oil radiators must be installed due to high heat load. The oil radiator is arranged in the lubricating oil circuit, and its working principle is the same as that of the cooler.
The oil cooler is divided into air as the cooling medium and water as the cooling medium. The oil radiator is generally a tubular structure similar to the water radiator of the cooling system, which is usually installed in front or behind the water radiator. The utility model is characterized by simple structure, no possibility of cooling water penetrating into the engine oil, and is suitable for traveling diesel engines.
There are two types of oil cooler: tube type and plate-fin type. The radiator core of the tubular water-cooled oil cooler is composed of steel pipes with fins, and both ends are connected with the water pipes in front of and behind the radiator. When the diesel generator set is working, the cooling water flows in the pipe, and the oil is limited by the spacer outside the pipe, and flows to the oil outlet in a curved line. The heat in the oil is transferred to the cooling water through the radiator.
If the oil cooler of the diesel generator set is blocked, it will also directly affect the normal heat dissipation of the oil, and will also cause other problems such as insufficient oil pressure. During daily maintenance, the oil cooler should also be checked regularly. If any problem is found, it should be cleaned or replaced in time.
