Filters Protect The Equipment From Working Properly
- Aug 11, 2017 -

Many companies will be installed clean production workshop with Filters to ensure clean room cleanliness. So after the installation of Filters must be leaked, because the installation of Filters when there may be some error, so that the phenomenon of Filters leakage. So, in the high-performance Filters after the installation of how to leak in the field?

Efficient Filters installation after the leak is different from the Filters manufacturers in the factory efficiency test. The latter only tests the efficiency of the Filters and other related properties, while the former involves Filters and leaks arising from a variety of factors related to the installation process. All will have a lot of companies will use the outlet leak detector for Filters leak detection.

When the leak is leaked, the aerosol is introduced from the upper side of the Filters and the scanning is performed at the lower air side of the Filters to detect the Filters medium of the Filters, the sealant Filters frame, the gasket, etc. Whether the leak.

In the test, if the indoor interference factor is too much, in order to eliminate interference, can be installed in the outlet outlet isolation cover, in the hood to detect, so that the detection data is more accurate.

In particular, it is important to note that the leak between the Filters and the mounting frame can be leaked along the mounting frame, or it can be leaked on the cross-section of the air outlet box, but to avoid the interference of the suction airflow The fouling of the body, especially the sampling port can not touch the frame of the efficient tuyere box or Filters.

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, the Filters resistance loss calculation

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