Liquid filter is an indispensable device on the pipeline for conveying media, usually installed at the inlet end of pressure reducing valves, relief valves, constant water level valves or other equipment, to eliminate impurities in the medium and protect the normal use of valves and equipment. When the fluid enters the filter cartridge with a certain specification filter, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is needed, simply remove the detachable filter cartridge, process it, and reinstall it. Therefore, it is extremely convenient to use and maintain.

Classification of liquid filters:

1. According to the filter media, it is divided into:

air filter

To purify polluted air to the level required for production and daily life, that is, to achieve a certain degree of cleanliness.

liquid filter

Clean the contaminated liquid to the required state for production and daily life, that is, to achieve a certain degree of cleanliness.

network filter

By setting up settings to block junk information, the information appearing on the computer screen should meet the requirements as much as possible. The principle of co absorption separates light of different colors

Light filter

Absorb some unwanted light.

2. According to the installation method:

Oil absorption filter

Return oil filter

in-line filter

3. Divided by performance:

in-line filter

Double tube filter

High pressure filter

The above mentioned should be a mesh filter. In fact, there are many types of filters, such as laminated filters, sand filters, carbon filters, plate and frame filters, bag filters, etc. The main principle is to use the pore size of the filter medium to intercept substances smaller than the pore size of the medium. Of course, some filter media also have special effects such as adsorption. Most filters are not that troublesome to backwash, as long as clean water is introduced from one end of the filtered water into the medium in the backwash filter, a good backwashing effect can be achieved.
