Abstract
Mechanical cleaning filters are used to purify water, aqueous solutions, liquid and gaseous substances, hy-drocarbons, air from solid suspended particles of various sizes. Filters used in the field are steel cylindrical apparatuses with a solid and detachable body, inside which slotted or mesh filter partitions are installed, contributing to the purification of water. The principle of operation of mechanical cleaning filters is that when the filtrated medium passes through the filter element, solid particles will be retained. The main feature of such filters is the frequency of action due to the need to clean the filter element manually or automatically using a reverse flow of clean water. With a decrease in productivity, namely, with an increase in the pressure drop between the inlet and outlet, as well as in the lower part of the device, manual or automatic cleaning of the filter element from accumulated contaminants will occur. The article highlights the principle of sliding couplings for filters for water purification, as well as their use in construction. The stages of cleaning and the materials from which sliding filters are made to prevent leakage are considered. Recommendations are given for careful monitoring and following proper procedures to prevent leaks and pressure losses, to ensure the structural integrity and stability of the well, as well as to exclude contamination of the surrounding groundwater. The use of a mechanical filter is proposed, the body of which is designed for heating or fixing thermal insulation and which can be used with small flows of viscous media for cleaning from impurities.
