Ama-Hydraulic Seals: Izingxenye Ezibalulekile Zezinhlelo Zamandla Amanzi
Izigxivizo ze-hydraulic ziyizingxenye ezibalulekile ezinhlelweni zamandla oketshezi, eziqinisekisa ukusebenza okungavuzi futhi zivikele ekungcoleni.Asetshenziselwa ukuvala isixhumi esibonakalayo phakathi kwezindawo ezimbili, njenge-cylinder rod kanye negland, kumasistimu asebenza ngamanzi.Lokhu kusiza ukugcina ingcindezi, kuvimbele ukuvuza koketshezi, futhi kugcine kungangeni uthuli, ukungcola, nokunye ukungcola okungase kulimaze isistimu.
Kunezinhlobo ezimbalwa zama-hydraulic seals, ngayinye yakhelwe ukuhlangabezana nengcindezi ethile, izinga lokushisa, kanye nezidingo zokuhambisana nemidiya.Ezinye izinhlobo ezijwayelekile zihlanganisa ama-O-rings, ama-piston seal, ama-rod seal, ama-wiper seal, nama-rotary seal.Ama-O-rings awuhlobo olulula noluvame ukusetshenziswa kakhulu lwe-hydraulic seal futhi asetshenziselwa ukuvala phakathi kwezingxenye ezimile neziguquguqukayo ohlelweni lwamandla oketshezi.Ama-piston seal asetshenziselwa ukuvimbela ukuvuza koketshezi ezizungeze i-piston, kuyilapho ama-rod seal asetshenziselwa ukuvimbela ukuvuza koketshezi eduze kwenduku.I-Wiper seal isetshenziselwa ukuhlanza ukungcola entongeni njengoba ingena futhi iphuma kusilinda, kuyilapho izigxivizo ezijikelezayo zisetshenziswa ekusetshenzisweni okujikelezayo ukuvimbela ukuvuza koketshezi eduze kwe-shaft.
Izigxivizo ze-hydraulic zenziwe ngezinto ezihlukahlukene, kuhlanganise ne-elastomers, i-polyurethane, i-fluorocarbons, ne-thermoplastics.Ukukhethwa kwezinto kuncike ezimeni zokusebenza zesistimu, okuhlanganisa izinga lokushisa, ukucindezela, nokuhambisana kwamakhemikhali.Ama-elastomers ayizinto eziguquguqukayo ezivame ukusetshenziswa kuma-hydraulic seals futhi anikeze ukusebenza okuhle kokuvala kanye nokumelana nokuhuzuka.I-polyurethane iyinto eqinile evame ukusetshenziselwa ukumelana nokugqokwa kwayo okuhle kakhulu, kuyilapho ama-fluorocarbon asetshenziselwa ukumelana kwawo namakhemikhali okuhle kakhulu.Ama-Thermoplastics asetshenziswa kuma-seal adinga ukuzinza okuhle kwe-dimensional kanye nesethi yokucindezela okuphansi.
Ukufakwa kwezimpawu ze-hydraulic kuwukucatshangelwa okubalulekile ukuze kuqinisekiswe ukusebenza okufanele nokuhlala isikhathi eside kohlelo.Ukufakwa ngendlela efanele kudinga amathuluzi namasu afanele, okuhlanganisa indawo yokuhlala efanele kanye nokugcotshwa.Amasistimu ophawu angafakiwe kahle angathola ukuvuza, ukuguga ngaphambi kwesikhathi, nezinye izinkinga ezingaba yingozi kusistimu.
Ama-hydraulic seal ayizingxenye ezibalulekile ezinhlelweni zamandla oketshezi, ezihlinzeka ngokusebenza okungavuzi kanye nokuvikela ekungcoleni.Izinhlobo ezahlukene zezimpawu ziklanyelwe ukuhlangabezana nezidingo ezithile futhi zenziwa ngezinto ezihlukahlukene ukuze zihlangabezane nezimo ezihlukahlukene zokusebenza.Ukufakwa ngendlela efanele kubalulekile ekuphileni isikhathi eside kanye nokusebenza ngendlela efanele kwesistimu.Ukugcinwa okuvamile nokushintshwa kwezigxivizo njengoba kudingeka kungasiza ukunweba impilo yesistimu futhi kuvimbele ukulungiswa okubizayo noma ukushintshwa kwezingxenye.
Kubalulekile futhi ukukhetha uphawu olulungile lwe-hydraulic lwesistimu yakho.Uphawu olulungile luncike ezicini eziningana, njengohlobo loketshezi olusetshenzisiwe, izinga lokushisa lokusebenza, ingcindezi yokusebenza, nobukhulu nokuma kwezingxenye ezivalwayo.Kubalulekile futhi ukucabangela uhlobo lokunyakaza oluhilelekile ohlelweni, njengokunyakaza okuqondile noma okujikelezayo, njengoba lokhu kungase kuthinte uhlobo lophawu oludingekayo.
Lapho ukhetha uphawu olusebenzisa amanzi amaningi, kubalulekile ukusebenzisana nomphakeli ohloniphekile onganikeza iseluleko nosizo lochwepheshe.Umphakeli kufanele akwazi ukuhlinzeka ngamashidi edatha nolwazi lobuchwepheshe kuma-seal abawanikezayo, okuhlanganisa izinga lokushisa lokusebenza nemikhawulo yokucindezela, ukuhambisana kwamakhemikhali, nezici zokusebenza.Kufanele futhi bakwazi ukunikeza isiqondiso ekufakweni kwezigxivizo, ukulungiswa, kanye nokushintshwa.
Ukugcinwa njalo nokuhlolwa kwezimpawu ze-hydraulic kubalulekile ukuze kuqinisekiswe impilo ende yesistimu nokuthembeka.Lokhu kuhlanganisa ukuhlola njalo izimvu zamanzi ukuthi azigugile noma azilimele futhi zishintshe uma kudingeka.Kubalulekile futhi ukuhlola ngezikhathi ezithile izinga loketshezi kanye nekhwalithi ohlelweni bese ubuyisela uketshezi njengoba kudingeka.Ukuhlanzwa okuvamile kwezingxenye zesistimu nokugcinwa okufanele kwesistimu lapho ingasetshenziswa nakho kungasiza ukunweba isikhathi sophawu futhi kuvikeleke ekungcoleni.
Ama-hydraulic seal ayizici ezibalulekile ezinhlelweni zamandla oketshezi, ezihlinzeka ngokusebenza okungavuzi kanye nokuvikela ekungcoleni.Ukukhetha okufanele, ukufakwa nokugcinwa kwezimpawu ze-hydraulic kubalulekile ukuze kuqinisekiswe impilo ende yesistimu nokuthembeka.Lapho ukhetha uphawu olusebenzisa amanzi amaningi, kubalulekile ukusebenzisana nomhlinzeki othembekile onganikeza isiqondiso nokusekelwa kochwepheshe.Ukugcinwa njalo nokuhlolwa kwezimpawu, kanye nokunakekelwa okufanele nokugcinwa kwesistimu, kungasiza ukunweba impilo yesistimu futhi kuvimbele ukulungiswa okubizayo noma ukushintshwa kwezingxenye.
