How long is the replacement cycle of the oil purifier filter?

1. General range of replacement cycle:

Under normal circumstances, the service life of the filter is about 500~1000 hours, or according to the maintenance cycle of the hydraulic system (usually about 3 months), it is recommended to ｒｅｐｌａｃｅ the filter element every 3 months to ensure the normal operation of the hydraulic system.

2. Factors affecting the replacement cycle

Frequency of use: 

The filtering effect of the filter element will gradually decrease with the passage of time and the increase in the amount of oil treated. Therefore, the replacement cycle of the filter element of the oil filter with a higher frequency of use may be relatively short. 

Filtration accuracy: 

Filter elements of different precisions have different abilities to remove impurities in the oil. High-precision filter elements may be more easily clogged, thereby shortening the replacement cycle. 

Working environment: 

If the working environment of the oil purifier is harsh, such as the oil containing a large amount of impurities, and moisture, or is under high temperature and high pressure, the filter element may be clogged or damaged faster, requiring more frequent replacement. 

Oil quality: 

The quality of the oil will also affect the replacement cycle of the filter element. If the impurity content in the oil is high, the filtering burden of the filter element will increase, and the replacement cycle will be shortened accordingly.

3. Basis for judging replacement standards

Pressure differential detection: The degree of blockage of the filter element is determined by detecting the pressure differential before and after the filter element. When the pressure differential reaches a certain level (such as the maximum pressure differential specified by the manufacturer), the filter element needs to be replaced. 

Use time record:

The replacement cycle is calculated based on the use time of the oil purifier and the service life of the filter element. However, this method may not be accurate enough because the actual use may differ from the theoretical value. 

Regular inspection: 

Regularly inspect and maintain the oil purifier, including checking the blockage of the filter element and the quality of the oil. Decide whether the filter element needs to be replaced based on the inspection results.

4. Replacement precautions

Choose a reliable filter element: When replacing the filter element, you should choose a reliable filter element brand and model to ensure the filtering effect and service life of the filter element. 

Correct installation and use: 

Install and use the filter element correctly according to the instructions to avoid damage to the hydraulic system.

In summary, the replacement standard of the oil purifier element is a problem that needs to be flexibly adjusted according to actual conditions. To ensure the normal operation of the hydraulic system and the stability of the oil quality, it is recommended that users comprehensively consider factors such as the frequency of use of the oil purifier, the working environment, the oil quality, and the filtering accuracy of the filter element to determine the replacement cycle, and perform regular inspections and maintenance.
