Centrifugal pump inlet filter
Thread Content
The resistance of the inlet filter on a centrifugal pump should increase over time; could it suddenly decrease?
Dirt will accumulate more and more. Except in special cases.
Sudden reduction in size may be due to a broken filter screen, allowing impurities to enter the centrifugal pump directly, which can damage the impeller and block the pipes, leading to even more serious consequences
1. If the pressure measurement tube is unobstructed, a sudden decrease in the filter’s pressure drop is mainly caused by damaged filter elements. 2. If the pressure measurement tube is blocked, the value of the filter’s pressure drop becomes unreliable. 3. Fortunately, shutting down the pump for inspection is not a complicated process
Yes, there are two layers of filters: a soft outer layer and a harder layer with a relatively larger pore size; it’s possible that the outer layer of the filter is damaged.
