What’s the characteristics of high-precision and strong stainless steel filter screen?

Stainless steel filter screen has many advantages, such as: high precision, high strength, corrosion resistance, the general filtering accuracy can reach 30 microns. During the anti-cleaning process, each filter screen has been backwashed, and this filter screen can continue to filter without being affected at all. Through its own retrieval and response functions, the process of automatic backwashing is completed, which can cope with unstable water quality without manual intervention.

This kind of filter can adjust the backwash pressure difference and time setting value according to different water sources and filtration accuracy. It uses the method of pneumatic blowdown valve to reduce the time of backwashing, less water consumption for backwashing, and environmental protection and economy. The filter element of this kind of filter is made of high-quality filter mesh, and the filter element is generally automatically cleaned by punctual control.

In the process of its operation, the impurities in the filter are blocked on the surface of the filter element, causing the inlet and outlet pressure difference to increase to the set value, or when the timer reaches the preset time, the electric control box announces a signal to drive the backwash organization . When the backwash suction cup is facing the inlet of the filter element, the blowdown valve is opened. At this time, the system releases pressure and drains. A negative pressure zone appears on the inside of the suction cup and the filter element, which is lower than the water pressure outside the filter element, forcing some net circulating water from the filter element. The outside flows into the inside of the filter element, and the impurity particles adsorbed on the inner wall of the filter element flow into the pan with water and are discharged from the drain valve.

Although the stainless steel screen has many advantages and a wide range of applications, it is the most important in terms of quality. Inexpensive stainless steel screens have relatively large flat steel thickness tolerances, which will have an inevitable impact on the bearing capacity. Therefore, price is not a primary factor. When choosing a stainless steel screen, pay attention to whether the mesh of the stainless steel screen is symmetrical and flat.
