Y filter, also known as decontamination, filter valve, is an indispensable device of conveying medium pipeline system, its role is the mechanical impurities in the filter medium, can on the sewage rust, sand, a small amount of solid particles in the liquid filter to protect the equipment pipe accessories from wear and blockage, can protect the normal work of equipment.
Principle:
1. Bubble point method test principle: when the filter membrane and filter element with a certain solution completely infiltration, and then through the gas source on the side (our instrument has intake control system, can stabilize pressure), adjust the intake), with the increase of pressure, the gas from the side of the filter membrane, show the membrane side of the size, number of bubbles, through the instrument to determine the corresponding pressure value is the bubble point.
2. Diffusion flow method test principle: diffusion flow test refers to when the gas pressure is 80% of the blebbing point value of the filter element, then there is not a large number of gas perforation, only a small amount of gas first dissolved into the diaphragm of the liquid phase, and then diffuse from the liquid phase to the gas phase on the other side, this part of the gas is called diffusion flow.
3. Why does the method of diffusion flow be better: the foaming point value is only a qualitative value, from the beginning to the last group foaming is a relatively long process, which cannot be accurately quantified. The measurement of diffusion flow value is a quantitative value, not only can accurately determine the integrity of the Y Strainer, but also can reflect the porosity, flow rate and effective filtration area of the membrane.
4. Test principle of the water intrusion method: The water intrusion method is dedicated to the test of the hydrophobic filter element, the hydrophobic membrane is resistant to water, the smaller the aperture, the greater the pressure needed to squeeze the water into the hydrophobic film. So under a certain pressure, the water flow squeezed into the filter film is measured to determine the aperture of the filter element.
Installation attention: 1. Steam or gas pipe: filter toward the horizontal direction; 2. Liquid pipe: filter toward toward the downward installation; 3. Vertical installation: according to the filter installation pointing.
Product application: Y Plastic Strainer, as an indispensable efficient filtration equipment in purification equipment engineering, has played a great role in the treatment of domestic wastewater and industrial sewage. With its advantages in design and application, it has now been favored.
Y-type filter in the application of various industries has effectively treated a large number of domestic and industrial sewage, so that the valuable water resources have been effectively reused, saving a lot of water resources. The advantages of Y PVC Strainer operation include full automation, maintenance-free, large filter area, high filter efficiency, long service life, stainless steel material, optional filter accuracy, and complete specifications. Compared with other filtration equipment, it is one of the most effective equipment in reclaimed water reuse engineering. And the water quality after the Plastic Filter treatment not only meets the national discharge standards, but also realizes the purpose of reuse and recycling.
