深入分析润滑油的黏度怎么样

润滑油的黏度不仅仅润滑油归类的依据,而且也与柴油发动机的输出功率非己、健身运动零部件的损坏水平、活塞环的密封性水平、润滑油及随后的销售量量、柴油发动机冷启动的轻捷性、零配件的溫度等息息相关,假如光滑油的粘度过大,会有以下几个方面的问题。

The viscosity of lubricating oil is not only the basis of classification of lubricating oil, but also closely related to the output power of diesel engine, the damage level of fitness parts, the sealing level of piston rings, lubricating oil and subsequent sales volume, the lightness of cold start of diesel engine and the temperature of spare parts. If the viscosity of lubricating oil is too high, the following questions will be asked. Question.

柴油发动机超低温启动艰难,机油粘度过大,在柴油发动机超低温启动时打油很慢,汽压虽然高,但汽车机油历经量不多,主要由于黏度大,油的泵送性能差,此时容易展现临时的干矛盾或半流体矛盾,这是发动机磨损的首要原因。试验证明,自发动机发动时,去后滚动所需的转矩就大,因而转速低,不易发动。

It is difficult for diesel engine to start at ultra-low temperature, and the oil viscosity is too high. When diesel engine starts at ultra-low temperature, the oil is pumped very slowly. Although the steam pressure is high, the amount of automobile oil experienced is not much. It is mainly due to the high viscosity and poor pumping performance of the oil. At this time, it is easy to show temporary dry or semi-fluid contradictions, which is the primary cause of engine wear. The test proves that when the engine is started, the required torque for rolling after removal is large, so the speed is low and it is not easy to start.

输出功率遗失大,机油粘度大,零部件矛盾表面的矛盾摩擦阻力也就加上,那样不只使零部件损坏加上,而且矛盾遗失输出功率也加上,与此同时,发动机曲轴搅拌成品油成品油的摩擦阻力也会扩大,构成发动机内部的丢失功率增多,也就降低了发动机的有用功率。

The loss of output power is large, the oil viscosity is high, and the contradictory frictional resistance on the contradictory surface of the parts is added, which not only damages the parts, but also adds the contradictory loss of output power. At the same time, the friction resistance of the engine crankshaft mixing the finished oil will also expand, and the loss power inside the engine will increase, thus reducing the useful power of the engine. 。

水冷却实际效果差,机油粘度大,流通性差,循环系统很慢,从矛盾表面带去发热量的速率也就慢,其水冷却实际效果也就差,易造成柴油发动机超温,清理实际效果差,汽车机油难度系数大,油的循环速度慢,经过滤清器的次数也就少,不能及时把磨损下来的金属碎屑、碳粒、尘土等杂志从冲突外表带走。

The actual effect of water cooling is poor, the oil viscosity is high, the circulation is poor, the circulation system is very slow, the rate of heat generation from the contradictory surface is slow, and the actual effect of water cooling is also poor. It is easy to cause diesel engine overtemperature, poor cleaning effect, high difficulty coefficient of automobile oil, slow circulation speed of oil, less times of passing through filters, and can not wear down gold in time. Magazines such as debris, carbon and dust were taken away from the surface of the conflict.http://www.sdpsrhy.com/
