The working principle of the hydraulic oil vacuum oil filter is as follows:
1. Vacuum degassing: Firstly, the hydraulic oil is placed in the processing chamber of the vacuum oil filter, creating a vacuum environment. Under the action of vacuum, the gas and water in hydraulic oil will be evaporated, thereby improving the stability and antioxidant capacity of hydraulic oil.
2. Filtering: Hydraulic oil passes through a filter element or filter screen, which can effectively capture solid particles, impurities, and pollutants in the oil. Different filters can filter particles of different sizes, ranging from tiny micrometer sized particles to larger impurities, to ensure the cleanliness of hydraulic oil.
3. Dehydration treatment: Moisture is another common pollutant in hydraulic oil. The hydraulic oil vacuum oil filter can remove moisture through physical and chemical methods to prevent oxidation and corrosion caused by moisture.
4. Oil quality analysis: Some advanced hydraulic oil vacuum filters may be equipped with oil quality analysis instruments, which can monitor the performance indicators of hydraulic oil, such as viscosity, acid value, and alkali value. This helps determine when hydraulic oil needs to be replaced.
