1. The filter element is clogged and not replaced in time. The filter element is seriously blocked by pollutants during work and has not been cleaned in time, resulting in an increase in the pressure difference of the filter element, and insufficient strength of the filter element, resulting in flattening of the filter element.

2. Improper selection of the filter element. When selecting the filter element, it is not suitable for the current working environment. The precision of the filter element is too high, or the pressure exceeds its allowable working pressure. It will also lead to the phenomenon of filter element sucking flat. Many customers think that this situation will be avoided by choosing stainless steel sintered mesh filter elements and sintered felt filter elements, but this is not the case. Although these two types of stainless steel filter elements have a certain compressive capacity, they exceed their own compressive capacity. , There will also be a phenomenon of flattening. We need to make appropriate adjustments according to the working pressure, such as adding a skeleton, so that the effect will be better

3. Improper installation, the installation of the filter element should be accurate and stable, and the filtration work has already started before the filter element is fixed, so that the filter element is damaged.
