What should I pay attention to when replacing hydraulic oil in a hydraulic press?

Hydraulic oil is very important for hydraulic machines. Although hydraulic oil is not a part of the hydraulic machine‘s body, we can see its position by looking at its name. Therefore, treat hydraulic oil the same as important parts of a hydraulic machine. It is necessary to change regularly and check regularly.
During the operation of the hydraulic press, the hydraulic oil will be lost and possibly transformed. Hydraulic oil will gradually deteriorate due to mechanical, physical and chemical effects. When the quality of the operating medium is reduced to a level that does not meet the target requirements, it must be replaced in time. Once hydraulic oil is produced, it will face the threat of metamorphosis. In the long-term storage process, the particulate contaminants in the oil have a tendency to agglomerate into agglomerates. During the transportation, due to the impact of the sensation, agglomeration will occur in the tiny particles. After finally entering the hydraulic system for operation, the fission speed will be greatly accelerated.

Taking mineral oil hydraulic oil as an example, more than 96% of the components are carbon and hydrogen compounds—hydrocarbons, and the rest are sulfur, nitrogen, and ash. It also participates in various additives such as anti-oxidation, anti-wear, anti-rust, defoaming, and pour point depressant according to demand. The time in the hydraulic system is also affected by external factors such as air, moisture, impurities, heat, light, and mechanical agitation. At the same time, the effects of internal factors such as the chemical composition of the hydraulic oil and the nature of additives will also cause various physical changes. And chemical changes make the hydraulic oil gradually age and metamorphose. Therefore, it is necessary to check the hydraulic oil time and minutes if it is not available. Perhaps it is no longer satisfied with the operating requirements of the hydraulic machine. If it changes, it must be replaced with a new hydraulic oil, otherwise it will not affect the hydraulic machine.
