Carbon steel filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect valves and equipment’s normal use.
When the fluid enters the filter cartridge with a certain size filter, its impurities are blocked, and the cleaned filtrate is discharged from the filter outlet. When cleaning is required, the removable filter cartridge is taken out, and then reloaded after processing. Yes, therefore, it is extremely convenient to use and maintain.
General principles for filter selection:
1. Import and export routes
In principle, the inlet and outlet diameter of the filter should not be less than the inlet diameter of the matching pump, which is generally consistent with the diameter of the inlet pipe.
2. Nominal pressure
The pressure rating of the filter is determined by the highest pressure that may occur in the filter line.
3. The choice of the number of holes:
The main consideration is the particle size of the impurities to be intercepted, depending on the process requirements of the media process. The size of the screen that can be intercepted by various specifications of the screen can be found in the table below.
4. Filter material
The material of the filter is generally chosen to be the same as the material of the connected process pipe. For different service conditions, consider a filter made of cast iron, carbon steel, low alloy steel or stainless steel.
5. Filter resistance loss calculation
Water filter, the pressure loss is 0.52~1.2kpa at the general rated flow rate working principle:
The carbon steel filter utilizes one or several kinds of filter media to pass the raw liquid through the medium under a certain pressure to remove impurities, thereby achieving the purpose of filtration. The fillers contained therein are generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc., and users can choose to use according to actual conditions.
The carbon steel filter is mainly used to reduce the turbidity in the water, and to remove the suspended water, organic matter, colloidal particles, microorganisms, chlorine smell and some heavy metal ions in the water, so that the water is purified.
