In high temperature weather, what should be paid attention to when using lubricating oil?


One of the most important criteria for controlling the operating temperature of the equipment and avoiding exposure to industrial lubricants is the quality of oxidation! In the process of storage and use, oil and air contact and oxidation is inevitable. The longer the contact time, the higher the temperature, the deeper the degree of oxidation, the irreversible changes in some properties of the oil, such as increased acid value, increased viscosity, increased sediment, darker color, etc., these changes greatly shorten the service life of the oil. The oxidizing property of the oil is closely related to the nature of the base oil used, the depth of refining, the characteristics and quality of the additives, the ratio and the modulation process. Therefore, in the current high temperature environment, try to keep your equipment from running too high temperature, avoid exposure and so on. Because the ambient temperature is relatively high, the equipment is often in a high temperature state, which is easy to cause rapid oxidation and deterioration of hydraulic oil and guide oil, the viscosity decreases, and the lubrication function is lost. Therefore, special attention should be paid to the equipment cooling system in the summer to ensure that it can work normally and avoid high temperature overheating of the transmission device.


The viscosity of lubricating oil changes with the increase of temperature, that is, the viscosity of lubricating oil decreases when it is heated, which is easy to cause excessive consumption of lubricating oil, so pay special attention to check the dipstick frequently in summer, and if there is a defect, it should be supplemented in time. Often heavy duty or relatively old lathes should pay attention to avoid low oil pressure due to low viscosity of cutting oil, causing unnecessary failures. If there is an anomaly, stop the car immediately to find the cause, and only after troubleshooting can you continue to work.
