Selection And Application Of The Strainer

Principle Requirements for Strainer Selection:

Strainer is a small equipment to remove a small amount of solid particles in the liquid, which can protect the normal work of the equipment. When the fluid enters the filter drum with a certain size of the filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When it is necessary to clean, as long as the detachable filter drum is taken out and reloaded after processing.
1.The inlet and outlet diameter of Strainers:
In principle, the inlet and outlet diameter of Strainers should not be smaller than the matching pump inlet diameter, generally consistent with the inlet pipe diameter.
2.Nominal pressure selection:
Determine the filter pressure level according to the highest possible pressure in the filter line.
3.Selection of the number of holes:
The selection of filter hole number mainly considers the particle size of the impurities to be intercepted, according to the technological requirements of the medium process.
4.Strainers material:
Generally, the material of the Strainer is the same as that of the process pipe connected. For different service conditions, cast iron, carbon steel, low alloy steel or stainless steel strainers can be considered.
5.Resistance loss calculation of Strainers
For water strainers, the pressure loss is 0.52 ~ 1.2kpa at the rated flow rate.

Application of the Strainers:

1.Stainless steel strainers
Stainless steel strainers are widely used in steam, air, water, oil products, and other media pipelines;Protect the pipeline system of various equipment, water pumps, valves, etc.It is free from blockage and damage caused by impurities such as rust and welding slag in the pipeline.Stainless steel filter has the characteristics of strong anti-fouling, convenient blowdown, large circulation area, small pressure loss, simple structure, small volume, light weight.The material of filter screen are stainless steel(strong corrosion resistance, long service life).

2.Y-type strainer
Y-type strainer is an indispensable filter device for conveying medium pipeline system. Y-type strainer is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve or other equipment to remove impurities in the media, in order to protect the normal use of valves and equipment.Y type filter has the characteristics of advanced structure, small resistance and convenient drainage.

3.Basket strainers
Basket filter is a small equipment to remove a small amount of solid in the liquid, which can protect the normal work of compressors, pumps and other equipment and instruments; It is also a small equipment to improve product purity and purify gas. Therefore, basket filter is widely used in petroleum, chemical, chemical fiber, medicine, food and other industries. Basket filter is composed of shell, blowdown cover, filter element, filter screen, bolt, etc.

4.T type strainers
T type strainers are widely used in steam, air, water, oil products, and other media pipelines;Protect the pipeline system of various equipment, water pumps, valves, etc.It is free from blockage and damage caused by impurities such as rust and welding slag in the pipeline.The T type filter produced by HEBEI BESTOP INDUSTRY SUPPLY CO.LTD has the characteristics of strong anti-fouling performance, convenient blowdown, large circulation area, small pressure loss, simple structure, small volume and so on; The screen material of T type strainer are stainless steel with the characteristics of corrosion resistance, long service life; T-type filter is also divided into straight flow and fold flow, the density of the filter screen has 10 mesh -120 mesh, temperature 0~450℃, can be selected according to user needs.
