Description
Technical Field
The utility model belongs to the technical field of heat dissipation of generator sets, and particularly relates to a lubricating oil cooling device for a generator set.
Background
Lubricating oil can effectively prevent the contact surface between the internal parts of the generator set from being worn, and the lubricating oil must have enough viscosity so as to form an oil film between the moving parts at various operating temperatures, and metal dust, carbon particles and dust which are worn down are cleaned out from the friction surface in time, thereby enabling the generator set to operate smoothly. The use of oils with excessive viscosity can create several disadvantages. First, when the viscosity is too high to affect the engine start, it is likely that severe wear will be caused at the engine start. The lubricating oil has high viscosity, slow flowing and high oil pressure, but the lubricating oil has low throughput and cannot be timely supplemented to the friction surface. The circulation speed of the oil also becomes slow and its cooling and heat dissipation effects become poor, thereby causing overheating of the engine. Because the circulation speed of the lubricating oil is low, the times of passing through the lubricating oil filter are reduced, and therefore, metal dust, carbon particles and dust which are worn down are difficult to clean from the friction surface in time. When the temperature of the lubricating oil rises along with the operation of the engine unit, the lubricating oil is thin, the abrasion of parts of the generator set can be accelerated, the power-limited operation of the engine unit is caused, and the generator set can be stopped in serious cases.
