What is Y Type Strainer?

The Y type strainer is an important equipment in the pipeline system of conveying medium. Its function is to filter mechanical impurities in the medium, filter rust, sand and other solid particles in sewage, protect equipment pipeline accessories from wear and blockage, and ensure the normal operation of the equipment.

What is the working principle of Y type strainer?

The first working principle is the bubble point test principle. When the filter membrane and filter element are completely infiltrated with a certain solution, then pass through the gas source on the side. As the pressure increases, the gas escapes from the side of the filter membrane, showing the size and number of bubbles on the side of the membrane. The corresponding pressure value measured by the instrument is the bubble point.

The second working principle of Y type strainer is the diffusion flow test principle. The diffusion flow test means that when the gas pressure is 80% of the bubble point value of the filter element, there will be no large amount of gas rushing out at this time, only a small amount of gas will first dissolve into the liquid phase on the diaphragm, and then diffuse from the liquid phase to the gas phase on the other side.

The third is the water intrusion test principle. The water intrusion method is specifically used to test hydrophobic filter elements. The hydrophobic membrane has a certain resistance to water. The smaller the pore size, the greater the pressure required to squeeze water into the hydrophobic membrane. Therefore, under a certain pressure, the pore size of the filter element can be determined by measuring the water flow rate squeezed into the filter membrane.
