How do people usually choose filters?
It depends on what your task is It’s just experience!
If you don’t clarify where it’s to be used, how can anyone answer?
A filter is selected before the oil pump inlet, mainly to filter out residues and other impurities in the oil. 3# qiantou
Your question is too vague. The selection of a filter is determined based on a combination of process conditions, process requirements, and medium characteristics; there are no universal guidelines, but one basic principle is that the filtration precision must be higher than the minimum allowable impurity level required by the equipment at the next stage. Here are a few examples: 1) Centrifugal pumps require a filter with a mesh size of 10–20 ； 2) Twin-screw pump, 30~40 mesh ； 3) Single-screw pumps are generally not required ； 4) Natural gas internal combustion engine, fine filter. Wait. It’s best for you to figure out exactly what operating conditions are involved before asking your question; otherwise, I won’t be able to answer you.
Choose the material first, then the mesh size of the filter
Before the oil pump inlet, we use a dual-filter. I wonder if you have a lot of traffic?
This question is too general. There are many factors to consider such as the medium, pressure, temperature, whether it’s possible to replace the filter element, and whether backwashing is required. You should ask a more specific question so that there is room for discussion
