Emkhakheni wobunjiniyela besimanje kagesi, ubuqotho bokuxhumeka kwekhebula kubaluleke kakhulu, ikakhulukazi uma kuziwa emishinini yamandla aphansi. Ukusebenza nokuthembeka kwale mishini kuvame ukuncika ekusebenzeni kwezixhumi zayo zamakhebula angangeni manzi. Lezi zixhumi azizona nje izingxenye ezilula; bangamaqhawe angacushiwe avikela izinhlelo zikagesi ezibalulekile emswakama, oqinisekisa ukusebenza okungenamthungo ezindaweni ezihlukahlukene. Lesi sihloko sicubungula ubuchwepheshe bakamuva bokuvalwa obunika amandla izixhumi zekhebula ezingangeni manzi, sikhanyisela ukuthi lezi zinto ezintsha zithuthukisa kanjani ukusebenza nokuphila isikhathi eside kwemishini yamandla aphansi.
Ukubaluleka kweIzixhumi Zekhebula Ezingangeni Manzi Emishinini Yamandla Aphansi
Imishini yamandla kagesi aphansi ibalulekile ezimbonini eziningi, kusukela kwezokukhiqiza nezezimoto kuye kumandla avuselelekayo kanye nezinto zikagesi ezithengwayo. Le mishini ivamise ukusebenza ezindaweni lapho ukuchayeka kumswakama kungenakugwema. Kungakhathaliseki ukuthi izimo ezimanzi zemboni yezimboni noma izilungiselelo zangaphandle zepulazi lelanga, ubungozi bokungena kwamanzi bungabangela amasekhethi amafushane, ukugqwala, futhi ekugcineni, ukwehluleka kwesistimu. Yilapho izixhumi zekhebula ezingangeni amanzi ziqala ukusebenza khona.
Izixhumi zamakhebula angangeni manzi ziklanyelwe ukudala umgoqo oqinile emanzini, ukuwavimbela ukuthi afinyelele lapho kuxhunywa khona ugesi. Akhiwe ukuze agcine ubuqotho ngaphansi kwezimo ezihlukahlukene, okuhlanganisa amazinga okushisa aguquguqukayo, ukucindezeleka komshini, nokuchayeka isikhathi eside emanzini. Ukusebenza kwalezi zixhumi kuncike kakhulu kubuchwepheshe bokuvala okusetshenziswayo.
Ubuchwepheshe Bokuvala Okuthuthukile Kuzixhumi Zekhebula Ezingangeni Manzi
I-Silicone Rubber Seals
Enye yezinto ezisetshenziswa kakhulu ezixhunyweni zamakhebula angangeni manzi irabha ye-silicone. Izigxivizo zenjoloba ye-Silicone zinikeza ukuguquguquka okukhethekile nokuqina, okuzivumela ukuthi zigcine uphawu oluqinile ngisho noma zingaphansi kwengcindezi yemishini. Lezi zimpawu zingamelana nezinhlobonhlobo zamazinga okushisa, zizenze zifaneleke kokubili izicelo zangaphakathi nangaphandle. Ukunwebeka kwerabha ye-silicone kuqinisekisa ukuthi ingakwazi ukuhambisana nokuma kwekhebula, idale umgoqo ongenamthungo ngokumelene nokungena kwamanzi.
I-EPDM (Ethylene Propylene Diene Monomer) Izimpawu
Izigxivizo ze-EPDM zingenye inketho ethandwayo yezixhumi zekhebula ezingenamanzi. Ezaziwa ngokumelana kwazo okuhle kakhulu nesimo sezulu nokuguga, izimvu zamanzi ze-EPDM zingabekezelela ukuchayeka isikhathi eside elangeni, i-ozone, kanye nomswakama. Lokhu kuzenza zibe zilungele izinhlelo zokusebenza zangaphandle lapho izixhumi zekhebula zivame ukuchayeka ezimweni ezinzima zemvelo. Izigxivizo ze-EPDM zibuye zibonise izakhiwo ezinhle zokuvala ugesi, zithuthukisa nakakhulu ukwethembeka kwemishini yamandla aphansi.
Izimpawu ze-polyurethane
Izigxivizo ze-polyurethane zithola amandla embonini ngenxa yamandla azo emishini ephakeme nokuqina kwawo. Lezi zimpawu zingamelana nokucindezela okuphezulu namandla emishini, okuzenza zifaneleke izinhlelo zokusebenza lapho izixhumi zekhebula zingaphansi kokucindezeleka okukhulu. Izigxivizo ze-polyurethane nazo zinikeza ukumelana okuhle kakhulu kumakhemikhali namafutha, okuqinisekisa ukuthi ahlala eqinile ngisho nasezindaweni zezimboni ezinezinto ezonakalisayo.
Iqhaza lama-Gaskets kanye ne-O-Rings
Ngokungeziwe ezintweni eziyisisekelo zokuvala, ama-gaskets nama-O-rings adlala indima ebalulekile ekuthuthukiseni amandla okuvikela amanzi ezixhumi zekhebula. Ama-gaskets ngokuvamile enziwa ngezinto ezifana nerabha ye-silicone noma i-EPDM futhi adizayinelwe ukuthi alingane kahle phakathi kwezingxenye zokuxhuma, okwenza isendlalelo esengeziwe sokuvikela ekungeneni kwamanzi. Ama-O-rings, ngakolunye uhlangothi, ayizigxivizo eziyindilinga ezibekwe eduze kwekhebula noma izindlu zokuxhuma. Zihlinzeka ngokuvala okuqinile ngokucindezela ngokumelene nezindawo zokukhwelana, zivimbele ngokuphumelelayo noma yiziphi izindlela zokungena kwamanzi.
Amazinga Wokuhlola Nezitifiketi
Ukuqinisekisa ukwethembeka nokusebenza kahle kwezixhumi zamakhebula angangeni manzi, zibhekana nokuhlolwa okuqinile kanye nezinqubo zokunikeza izitifiketi. Lokhu kuhlola kuhlola ikhono lezixhumi lokumelana nezimo ezihlukahlukene, okuhlanganisa umfutho wamanzi, ukushintshashintsha kwezinga lokushisa, nokucindezeleka komshini. Amazinga wesitifiketi afana ne-IP67 ne-IP68 ajwayele ukusetshenziselwa ukulinganisa amandla angangeni manzi ezixhumi zekhebula. Isilinganiso se-IP67 sibonisa ukuthi isixhumi singakwazi ukumelana nokucwiliswa emanzini kufika kumitha elingu-1 isikhathi esithile, kuyilapho isilinganiso se-IP68 sibonisa ukuthi singacwiliswa emanzini ajulile isikhathi eside ngaphandle kokungena kwamanzi.
Isiphetho
Intuthuko kubuchwepheshe bokuvala iguqule ukusebenza kwezixhumi zamakhebula angangeni manzi, okuzenze zaba yizingxenye ezibalulekile emishinini yamandla aphansi. Kusukela kuma-silicone enjoloba kanye nezigxivizo ze-EPDM kuye kwezigxivizo ze-polyurethane, impahla ngayinye inikeza izakhiwo ezihlukile ezihlangabezana nezidingo ezithile zohlelo lokusebenza. Ukuhlanganiswa kwama-gaskets nama-O-rings kuthuthukisa ngokwengeziwe amandla ezixhumi angangeni manzi, kuqinisekisa ukuthi angakwazi ukumelana nezimo ezinzima kakhulu. Njengoba izimboni ziqhubeka nokuthuthuka futhi zidinga amasistimu kagesi athembeke kakhudlwana, ukubaluleka kwezixhumi zekhebula ezingangeni amanzi ezisezingeni eliphezulu angeke zeqiswe. Ngokuhlala bazi ngobuchwepheshe bakamuva bokuvalwa nokunamathela ekuhlolweni okuqinile kanye nezindinganiso zokunikeza izitifiketi, abakhiqizi bangaletha izixhumi ezingahlangani nje kuphela kodwa ezidlule lokho okulindeleke kumakhasimende abo, ekugcineni ziqhubekisele phambili inqubekelaphambili yokufakwa kwemishini enamandla aphansi emikhakheni eyahlukene.
