filters selection principle requirements

     The filters is a small device that removes a small amount of solid particles in the liquid to protect the equipment from normal operation. When the fluid enters the cartridge with a certain size of the filters, the impurities are blocked and the clean filtrate is discharged from the filters outlet, When the need for cleaning, as long as the removable cartridge out, after processing can be reloaded.

1, the filters import and export diameter:

In principle, the filters inlet and outlet diameter should not be less than the matching pump inlet diameter, generally consistent with the inlet pipe diameter.

2, nominal pressure selection:

Determine the pressure level of the filters according to the maximum pressure that may occur with the filters line.

3, the number of holes in the choice:

The choice of the number of holes in the filters is mainly to consider the impurity particle size to be intercepted, depending on the process requirements of the media process. A variety of specifications can be intercepted screen size check the following table "filters specifications."

4, the filters material:

The material of the filters is generally chosen to be the same as that of the connected process piping. For different service conditions, consider selecting the filters for cast iron, carbon steel, low alloy steel or stainless steel.

5, filters resistance loss calculation

Water filters, the general calculation of the rated flow rate, the pressure loss of 0.52 ~ 1.2kpa.

filters application

1. Stainless steel filters

   Stainless steel filters widely used in steam, air, water, oil, and other media in the pipeline; to protect the pipeline system of various equipment, pumps, valves, etc .; from the pipeline rust, solder ballast and other impurities, And damaged. Stainless steel filters anti-fouling strong, convenient sewage, circulation area, the pressure loss is small, simple structure, small size, light weight. filters material are stainless steel, corrosion resistance, long service life.

2.Y type filters

   Y-type filters delivery medium piping system is an indispensable kind of filters device, Y-type filters is usually installed in the pressure relief valve, pressure relief valve, water level valve or other equipment, the inlet side, used to remove impurities in the media, To protect the normal use of valves and equipment. Y-type filters with advanced structure, low resistance, convenient sewage and so on.

3. Y-type rod extension filters

   Y-type rod extension and retractable filters with a new type of design, the Y-type filters and telescopic joint combination, simple structure, easy to use, to solve a variety of different standard products, the length of the flange caused by different fixed pipe installation inconvenience defects, The telescopic filters is mainly used for high-rise construction, multi-storey building or factory water supply and drainage piping, usually installed in the pressure relief valve, pressure relief valve, water level valve or other major equipment, the import side, the installation of the rod extension filters Remove pipe debris or disassemble to ensure the normal use of valves or equipment.

4. Basket filters

The basket filters removes small equipment with a small amount of solids in the liquid to protect the compressor, pumps and other equipment and instruments from working properly; it is also a small device to improve the purity of the product and purify the gas. Therefore, the basket filters is widely used in petroleum, chemical, chemical fiber, medicine, food and other industries. Basket filters with shell, sewage cover, filters, filters, bolts and other components.

5.T-type filters

   T-type filters is widely used in steam, air, water, oil and other media in the pipeline, the protection of pipeline systems on a variety of equipment, such as pumps, valves, etc., from the pipeline of rust, To block and damage the pipe. Shanghai-US valve Manufacturing Co., Ltd. production of T-type filters with strong anti-fouling, sewage convenience, large circulation area, the pressure loss is small, simple structure, small size and other characteristics; T-filters filters material are stainless steel, Corrosion resistance, long service life; T-type filters is also divided into DC and baffle, the filters density of 10 mesh-120 mesh, temperature 0 ~ 450 ℃, according to user needs to use.
