The selection of lubricating oil should consider the following factors Used in most casesLanzhou lubricating oilProducts can be roughly divided into industrial machinery lubricants and industrial production process oil two categories。The selection of lubricating oil is the main link of lubricating oil, which is the key to ensure reasonable lubrication of equipment and give full play to the performance of lubricating oil in Lanzhou。 First, the selection of Lanzhou lubricating oil should consider the following factors: 1.The working conditions of the mechanical equipment when it is actually used (i.e., working conditions);
Designating or recommending machinery manufacturer's manual;Regulations or suggestions of lubricant manufacturers in Lanzhou。
Second, choose Lanzhou lubricating oil performance indicators。 1.Viscosity: Viscosity is the index of Lanzhou lubricating oil classification, which has decisive significance for quality identification and determination。According to design or calculation data, determine the viscosity of lubricating oil used in equipment。 2.Pour point: Pour point is an indicator that indirectly indicates the low temperature fluidity of lubricating oil during storage, transportation and use。Experience The use temperature of lubricating oil in Lanzhou needs to be 5-10℃ higher than the pour point。 3.Flash point: Flash point mainly refers to the storage, transportation and use of lubricating oil in Lanzhou is an indicator of safety, but also an indicator of controlling the distillation and volatility of lubricating oil。The principle of the lubricating oil flash point index is to retain 1/2 of the quan coefficient in accordance with the quan provisions, that is, 1/2 higher than the actual use temperature。If the oil pan oil temperature of the internal combustion engine does not exceed 120 ° C, the flash point of the internal combustion engine oil is specified。 4.Selection of performance indicators: there are more performance indicators, and the difference between different varieties is large. It should be integrated with equipment working conditions, manufacturer requirements, oil description and introduction。Strive to meet the technical requirements of lubrication, economic and reasonable。
