银川Lubricant manufacturer

Lubricating oil plays a very important role in mechanical equipment, as it can reduce wear, friction, and heat loss while maintaining the normal operation of the equipment. However, as time passes, lubricating oil will gradually lose its performance and effectiveness, and it needs to be replaced in a timely manner. The following will introduce how to determine whether the lubricating oil needs to be replaced and the basis for the lubricating oil replacement cycle.

Method for determining whether lubricating oil needs to be replaced:

1. Observe the appearance and color of the lubricating oil: Under normal circumstances, fresh lubricating oil appears transparent or light yellow, and the appearance is clear. If you notice that the lubricating oil has become turbid, cloudy, or suspended, it may indicate that the lubricating oil has been contaminated or mixed with water and needs to be replaced.

2. Check the viscosity of lubricating oil: viscosity is a measure of the fluidity of lubricating oil. Over time, the viscosity of lubricating oil will change. If the viscosity of the lubricating oil is significantly high or low, it may indicate that it has lost its normal performance and needs to be replaced.

3. Observe the degree of oxidation of the lubricating oil: As the usage time increases, the lubricating oil will be oxidized, forming precipitates and colloidal substances, causing the lubricating oil to turn black. If the lubricating oil appears dark black and has a pungent odor, it may indicate that the lubricating oil has been excessively oxidized and needs to be replaced.

4. Measure the acid value of lubricating oil: Lubricating oil will produce acidic substances during use. By measuring the acid value of the lubricating oil, it can be determined whether the lubricating oil needs to be replaced. When the acid value of the lubricating oil exceeds the specified range, it indicates that the lubricating oil has lost its normal performance and needs to be replaced in a timely manner.

Basis for lubricating oil replacement cycle:

1. Manufacturer's suggestion: Each mechanical equipment manufacturer will provide recommended intervals for lubricating oil replacement. These suggestions are usually based on the usage of the device and the working environment. Users can refer to the replacement cycle provided by the manufacturer for lubricating oil replacement.

2. Working time or mileage: The cycle of lubricating oil replacement can also be based on the working time or mileage of the equipment. According to the frequency of use and working conditions of the equipment, an appropriate replacement cycle can be established. For example, some devices may require lubricating oil replacement every 5000 hours, while others may require lubricating oil replacement every 10000 kilometers.

3. Analysis of lubricating oil: Regular chemical analysis and physical performance testing of lubricating oil can help determine its service life. By analyzing the test results, it is possible to detect the degree of deterioration and contamination of the lubricating oil, as well as determine whether it is necessary to replace the lubricating oil.

In summary, determining whether lubricating oil needs to be replaced can be done by observing the appearance, color, viscosity, and oxidation degree of the lubricating oil, as well as measuring the acid value of the lubricating oil. The cycle of lubricating oil replacement can be determined based on the manufacturer's recommendations, working hours or mileage, and the analysis results of the lubricating oil. Regularly replacing lubricating oil and ensuring it is in good condition can extend the service life of the equipment and maintain its normal operation.
