Understand the standard knowledge of basket filter

Has anyone thought about how to keep the water we drink clean every day? How to ensure that the water we drink can completely remove harmful substances? Or our gasoline, how to get rid of some particulate matter and leave the usable part? When all these things we use need to be filtered before they can be used, Bunny will introduce the standard of basket filter to everyone and see how high the requirements of basket filter are! Basket filter standard

Manufacturing standard flange connected high and low nozzle basket filter for pipeline is mainly used for main technical parameters: shell material: carbon steel, stainless steel (sus304/sus304l/sus316/sus316l), fluorine lining and plastic (PP, PVC, etc.). ). Filter element material of coarse filter: the filter frame and screen are made of stainless steel. Sealing ring material.

Basket filter with nominal diameter 15mm and nominal pressure of 4.0PMa: LG- 15/4.0? JB/T？ 7538—94

Effective filtration area of filter

Selection of 1. pore number: mainly consider the particle size of trapped impurities, depending on the technological requirements of medium flow. See the following table "Screen Specifications" for the particle sizes that can be intercepted by various screens.

2. Inlet and outlet diameter: In principle, the inlet and outlet diameter of the filter should not be less than the inlet diameter of the matching pump, but it is generally the same as the diameter of the inlet pipeline.

3. Nominal pressure: Determine the pressure grade of the filter according to the highest possible pressure of the filter pipeline.

The main purpose of basket filter with flange connecting high and low nozzles.

Filter is a product that separates solid particles from fluid, improves product purity and protects equipment (compressor/pump/instrument, etc.). ) work safely.

Main technical parameters: shell material: carbon steel, stainless steel (sus304/sus304l/sus316/sus316l), fluorine lining, plastic (PP, PVC, etc.). ). Filter element material of coarse filter: the filter frame and screen are stainless steel.

Sealing ring material: PTFE. Working temperature: carbon steel -40℃~380℃, stainless steel -80℃~450℃? .

The above is the standard of basket filter introduced by rabbit. The standard of basket filter is strict, because it is related to the quality of our daily life, even the safety of life (when filtering domestic water). We can also know that the basket filter is mainly composed of connecting pipe, main pipe, filter basket, flange, flange cover and fasteners. When cleaning, we can open the bottom, drain the liquid, then disassemble the flange cover, clean it and reassemble it.
