What are the types, models, and functions of filters? How to choose the appropriate filtering equipment?

A filter, also known as a dirt remover or filter valve, has many definitions and is similar in nature. A filter refers to a small device installed on a pipeline to remove small amounts of solid particles from liquids or gases, which can protect the normal operation of the equipment and the purity of the medium. When the fluid enters a filter cartridge with a certain specification of filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is needed, Simply remove the detachable filter cartridge, dispose of it, and reinstall it. Filters mainly have the following types and functions: 1. Stainless steel filter Weidun VTON stainless steel filters are widely used in pipelines for various media such as steam, air, water, oil, etc; Protect various equipment, water pumps, valves, etc. in the pipeline system; Protected from blockage and damage caused by impurities such as rust and welding slag inside the pipeline. Stainless steel filters have strong stain resistance, convenient discharge, large flow area, small pressure loss, simple structure, small volume, and light weight. The filter mesh material is all stainless steel, with strong corrosion resistance and long service life. 2. Y-shaped filter Weidun VTONY filter is an indispensable filtering device in the pipeline system for conveying media. Y-type filters are usually installed at the inlet end of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities in the media and protect the normal use of valves and equipment. The Y-type filter has the characteristics of advanced structure, low resistance, and convenient discharge.

What is the principle of a filter?

The filters used in industry are all external pressure filters, composed of an external filter tank and an intermediate filter medium. Its basic working principle is The inside of the filter is supported by a metal mesh basket, and the liquid flows in from the inlet. After being filtered by the filter bag, it flows out from the outlet. Impurities are intercepted in the filter bag, and can be reused after replacing the filter bag. The side leakage probability of the filter bag is small, and the filtering accuracy is high, which can efficiently ensure the filtering effect. The internal and external surfaces of the filter are mechanically sandblasted and polished, which is average and easy to clean. We know that the filtering method adopted by bag filters is a side in and side out method, or a side in and bottom out method. The filtered liquid medium is pressed or pumped into the barrel of the bag filter through the pressure in the pipeline. The liquid medium to be filtered passes through the filtering bag supported by a metal mesh basket, and the changed solid and liquid respectively reach the result of the liquid medium being filtered. The filter has high filtration accuracy, up to 0.5 μ m. Can meet the needs of chip electrolyte filtration. According to the actual production needs, the filter has a reasonable overall structure, good sealing, strong circulation ability, and simple operation, which can meet the filtration needs of various industrial water. The probability of side leakage of the filter bag is low, and the filtering accuracy is high. The internal and external surfaces of the filter are solved by mechanical sandblasting polishing, which is average and easy to clean. We know that the flange quick opening stainless steel bag filter adopts a side in and side out method, with large inlet and outlet water volume, high water production, and stable water quality.
