What are the requirements for the use of hydraulic filters in hydraulic fittings?

We use a lot of hydraulic filters in hydraulic accessories, including high-pressure filters, oil suction filters, oil return filters, etc. There are about six requirements:

1. The key points for determining the filter efficiency at all levels are: the performance requirements of the final filter, the efficiency specifications of the prefilter should be reasonable, and the maintenance of the primary filter and the precision filter should be convenient.

2. Increase the filter area The filter has a large filter area, which can contain more dust and has a long service life. In addition, with a large filtering area, the velocity of airflow passing through the material is low, and the resistance of the filter is small.

3. Adjust the filter efficiency at all levels. The filter efficiency of the prefilter is low. The dust can be blocked in the prefilter by adjusting the filter efficiency of the prefilter.

4. The additional effect of the filter should not be emphasized.

5. If there are many willows and willows where the filter is used, corresponding measures should be taken during air conditioning design, such as changing the air inlet height or adding a protective screen at the air inlet. If the measures are not appropriate, there is only one way: change the filter frequently in the season of floating catkins.

6. Cleaning technology is difficult to promote the filter with high efficiency, and the use occasions are very particular. Even if the filter is not bad, it is better not to wash it, unless it is sure that it will be thoroughly cleaned and its performance will not change after cleaning.
