Wire-wound filter element as a security filter element, working water treatment industry comrades are not strange to it, then how to choose the appropriate wire-wound filter element in the process of use, will certainly affect its filtering time and filtering efficiency, the following we introduce the relevant parameters of wire-wound filter element!
1. The diameter of the filter medium particles;
The precision of the wire-wound filter element is 1-100 micron. We should choose the appropriate precision according to the filter medium. If the filter is very dirty water with fine precision, the service life of the filter element will definitely be greatly reduced.
2. The acidity or alkalinity of the filter medium;
The filter element is made of three materials.
PP, absorbent cotton, glass fiber, PP is more commonly used in water treatment, mainly filter neutral or weak acid and alkaline liquid, absorbent cotton and glass fiber can filter strong acid and alkali.
3. Temperature of the filter medium;
The skeleton of the wire-wound filter element is PP and stainless steel, the material is also described above, PP skeleton and PP material temperature resistance is low, stainless steel skeleton absorbent cotton and glass fiber temperature resistance is high
4. Pressure of the filter medium;
This is related to the skeleton of the filter element. PP skeleton has low withstand pressure and stainless steel skeleton has high withstand pressure. When the pressure is low, pressure needs to be pressurized and pressure needs to be reduced when the pressure is high.
The following is the temperature and pressure resistance of various materials of the wire-wound filter element;
Working pressure drop: 0.1kgf/cm2
* High pressure: 4kGF /cm2
* High pressure drop: 2kgf/cm2
* High operating temperature:
Polypropylene line, polypropylene skeleton 60℃
Polypropylene line, stainless steel skeleton 80℃
Defatted cotton thread, stainless steel skeleton 180℃
Glass and fiber wire, stainless steel skeleton 200℃
