Filters Ensure Proper Use Of Valves Or Equipment
- Jul 12, 2017 -

Filters is to remove a small amount of solid particles in the air, the Filters air in the tiny dust impurities or odor of gas, can protect the equipment in a clean environment to work or to ensure that the living space of the air clean, when the fluid into the home A certain Filters mesh Filters, the impurities or odor is blocked, and clean the flow of material through the Filters out.

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 Filters 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 removed, after processing can be reloaded.

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.

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

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

The material of the Filters is generally the same as that of the connected process piping. For different service conditions, it is possible to consider the choice of Filters for cast iron, carbon steel, low alloy steel or stainless steel.

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

Stainless steel Filters is 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 stains strong, easy to discharge, large circulation area, the pressure loss is small, simple structure, small size, light weight. Filters material are stainless steel, corrosion resistance, long service life.

Y-type Filters conveying 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 inlet, used to remove impurities in the media, To protect the normal use of valves and equipment. Y-type Filters with advanced structure, low resistance, easy to discharge and so on.

Y-type rod retractable Filters using 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 the installation of fixed pipe 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 end of the installation of the rod extension Filters easy Remove pipe debris or disassemble to ensure proper use of valves or equipment.

1 Filters accuracy

Filtration accuracy, indicating that the Filters on a variety of different sizes of particles Filters capacity, by the absolute Filters accuracy, filtration ratio, filtration efficiency and other parameters.

① Absolute Filters accuracy, refers to the size of the largest hard spherical particles through the Filters (μm). Measured by the test method, reflecting the maximum pore size of the Filters material.

② Filters ratio β, refers to the same size of the particles in the upstream of the Filters unit volume of oil, and the downstream unit volume of the ratio of the amount of oil. It can accurately reflect the Filterss on different sizes of particles of filtration capacity, has been adopted by the International Organization for Standardization to assess the accuracy of the Filters Filters performance indicators.

2 Filters pressure drop characteristics

The Filters has resistance. The system of oil, through the Filters must appear pressure drop.

Filters and flow must be, the Filters Filters the higher the accuracy, the greater the pressure drop; flow must be, Filters the larger the Filters area, the pressure drop is smaller; the greater the viscosity of the oil, the greater the pressure drop.

The pressure drop allowed by the Filters element is the maximum pressure drop that the Filters element can not withstand structural damage. In the high-pressure system in the stable work, the Filters is only where the pressure drop of oil, rather than pressure.

The pressure drop of the oil flowing through the Filters is largely determined by the test and empirical formula.

3 Filters capacity of the Filters

The amount of particles that can be Filtersed and accommodated before the pressure drop of the Filters reaches the specified value. This is an important indicator of the actual time that the Filters can be used continuously. The larger the capacity, the longer the time interval for replacement or cleaning. In general, the Filters size is large, that is, large Filters area, nanometer capacity is proportional to increase. This indicator can be determined by multiple performance tests.
