Abstract

Mechaniczne uszczelnienie czołowe, według patentu PL224773, charakteryzuje się tym, że nieobracający się pierścień uszczelniający (1) posiada wykonane wewnętrzne oddzielone od siebie współśrodkowe kanały (14) o przekroju prostokątnym lub kołowym, usytuowane w pobliżu powierzchni czołowej pierścienia (1), połączone z zewnętrznym regulowanym układem hydraulicznym. Korzystnie przesuwny nieobracający się pierścień uszczelniający (1) z wewnętrznymi kanałami (14) jest wykonany w technologii przyrostowej metodą selektywnego spiekania laserowego proszków. Korzystnie, w nieobracającym się pierścieniu uszczelniającym (1) wykonane są dwa, trzy lub cztery niepołączone ze sobą wewnętrzne kanały współśrodkowe (14), zaś wewnętrzne kanały współśrodkowe w nieobracającym się pierścieniu uszczelniającym (1) są połączone naprzemiennie poprzez przewody elastyczne (15, 16) z zewnętrznym regulowanym układem hydraulicznym.The mechanical face seal, according to patent PL224773, is characterized in that the non-rotating sealing ring (1) has made internal separated from each other concentric channels (14) of rectangular or circular cross-section, located near the face of the ring (1), connected to the outer adjustable hydraulic system. Preferably, the sliding non-rotating sealing ring (1) with internal channels (14) is made in the incremental technology by the selective laser sintering of powders. Preferably, two, three or four unconnected internal concentric ducts (14) are made in the non-rotating sealing ring (1), and the internal concentric ducts in the non-rotating sealing ring (1) are alternately connected by flexible hoses (15, 16) with external adjustable hydraulic system.
