ʻO ka mechanical seal he mea ia e pili ana i ka liʻiliʻi o ʻelua o ke kuʻekuʻe i ke axis o ka hoʻololi ʻana o ka ʻili hope i ke kaomi wai a me ka uku no ka hana o ka tissue elastic (a i ʻole magnetic) a me ka hui pūlima kōkua, no laila no ka mālama ʻana i ka pāpaʻi a me ka hoʻoheheʻe ʻana i nā mea hana e pale ai i ka leakage o ka wai. ʻO ka hana nui o nā sila mechanical ka pale ʻana i ka leakage o nā kinoea a me nā wai i nā noi shaft rotating. Hoʻohana nui ʻia ia i nā kikoʻī mechanical seal no ka pamu, agitator, compressor a me nā mea like ʻole,Sila mīkini maʻamaue hoʻokaʻawale maʻamau i ʻāpana mechanical seal asila mīkini pahu pahuma ka hui ana. A ʻo ka ʻāpana mechanical shaft seal hiki ke hoʻokaʻawale ʻia i lokohoʻokahi puna mechanical sila,ʻo ka nalu puna mechanical seals, Elastomer bellow mechanical sila ,metal bellow mechanical sealsetc. Hiki iā mākou ke hāʻawi i nā ʻano maʻamau like like o nā sila mechanical o nā inoa kaulana he nui e like me Eagle burgmann, AES, John crane a me Vulcan.
