The key selection parameters of T-type filters revolve around "adapting to the medium, meeting working conditions, and ensuring filtration efficiency". The key parameters are as follows:
1. Medium-related Parameters
Medium type: Specify whether it is water, oil, gas or other fluids. Different media correspond to filters of different materials.
Medium temperature/pressure: Must match the rated temperature and pressure of the filter to avoid material deformation or seal failure.
Medium viscosity: Viscosity affects fluid permeability, so the appropriate flow capacity should be selected based on viscosity.
2. Core Filtration Parameters
Filtration precision: Determined according to the requirements of subsequent equipment (unit: μm). For example, protecting precision instruments requires higher precision (such as 5-20 μm).
Nominal diameter: Consistent with the nominal diameter of the pipeline (e.g., DN15, DN50) to ensure smooth fluid flow.
3. Structural and Material Parameters
Body material: Selected according to the corrosiveness of the medium (e.g., carbon steel, stainless steel 304/316, copper, etc.).
Filter screen material: Must be compatible with the medium and wear-resistant. Common materials are stainless steel and brass, and the screen aperture corresponds to the filtration precision.
Connection method: Matches pipeline installation (e.g., threaded, flanged, welded connection).
4. Working Condition and Installation Parameters
Flow rate requirement: The rated flow rate of the filter must be greater than or equal to the actual working flow rate of the pipeline.
Installation space: Determined according to the structural length and inlet/outlet direction of the T-type filter, combined with the on-site space.
