The separation of solid particles in fluids by wire gauze inside a filter element is called "filtration", and the filter itself is called a "strainer".
The solid particles are trapped (filtered) by the gaps (designated mesh aperture) in the wire gauze.
In order to avoid being trapped, the fluid then flows to locations with less resistance, increasing the clogged areas.
As the clogging expands further, the fluid can only escape between the solid particles, but the spaces between the solid particles are smaller than the original gaps, which results in increased pressure loss.
The gaps are restored by removing the element periodically and cleaning it.
Wire gauze is used in the majority of Mizuno’s strainers.
・Mesh: The number of wires each 25.4 mm (1 inch).
|Plain weave||Items where a fixed interval is maintained between vertical wires and horizontal wires, and each individual wire crosses over or under each alternating wire, or equivalent items.|
|Twill weave||Items where a fixed interval is maintained between vertical wires and horizontal wires, and each individual wire crosses over or under alternating sets of 2 wires, or equivalent items. |
(As wires cross sets of 2 wires, the wire curvature angle is larger, allowing for use of comparatively larger wires.)
|Plain Dutch weave||Items which are woven like in a plain weave but where horizontal wires are woven in contact with each other.|
|Twilled Dutch weave||Items where a Dutch weave is woven like a twill weave with horizontal wires in contact with each other and overlapping in pairs, which makes it impossible to see the mesh and which uses diagonal gaps for filtration.|
