Yiziphi ezinye izinto ezibalulekile okufanele uzicabangele lapho ukhetha izinto zokuvala ezifanele zohlelo lokusebenza?
Intengo enhle nemibala efanelekile
Ukutholakala kwezimpawu
Zonke izici ezithonya ohlelweni lokuvala: isib. izinga lokushisa, uketshezi kanye nengcindezi
Lezi zonke izici ezibalulekile okufanele uzicabangele ohlelweni lwakho lokuvala. Uma zonke izici zaziwa, kuzoba lula ukukhetha izinto ezifanele.
Kodwa imfuneko iwukuthi izinto kumele ziqine. Ngakho-ke into yokuqala okufanele uyicabangele ukusebenza kobuchwepheshe. Ake siqale ngesici sokusebenza.
Isikhathi sokuphila kwesistimu kanye nezindleko kuyizinto ezibalulekile (I-TIanjin Tanggu Water-Seal Valve Co., Ltd) okufanele uzicabangele. Zonke izici zizothinta ukusebenza kohlelo lwakho lokusebenza. Kubalulekile ukucabangela izici zokuklama ngokwesicelo. Lokhu kufaka phakathi izinto ezisetshenzisiwe, izimo zehadiwe kanye nezinqubo zokukhiqiza. Kukhona nezici zemvelo okufanele uzicabangele okuhlanganisa: ingcindezi, izinga lokushisa, isikhathi, ukuhlanganiswa kanye nemidiya.
i-elastomer
Ama-elastomer athandwa ngenxa yokuqina kwawo okuhle. Ayikho enye into enezinga elifanayo lokuqina.
Ezinye izinto ezifana nama-polyurethane nama-thermoplastics zimelana kakhulu nengcindezi kune-elastomers.
Izinto zerabha zingasetshenziswa ezinhlotsheni ezahlukene zokusebenza.
Izakhiwo ezibalulekile zemishini zifaka phakathi
ukunwebeka
ubulukhuni
amandla okudonsa
Ezinye izici ezibalulekile zifaka phakathi
•Isethi yokucindezela
•ukumelana nokushisa
•ukuguquguquka kwezinga lokushisa eliphansi
•ukuhambisana kwamakhemikhali
•Ukulwa nokuguga
•ukumelana nokuklwebheka
Isici esibaluleke kakhulu ukunwebeka kwezinto zerabha. Ake sifunde kabanzi ngalokhu.
Ukunwebeka kuwumphumela we-vulcanization. Izinto ze-Elastomeric, njengerabha evulcanized, zizobuyela esimweni sazo sokuqala uma zikhubazekile.
Izinto eziqinile, njengerabha engavuthwanga, ngeke zibuyele esimweni sazo sokuqala uma zikhubazekile.ivalvu yebhabhathane ephindwe kabili) inqubo yokuguqula irabha ibe yinto ethambile.
Ukukhethwa kwama-elastomer kusekelwe kakhulu ku:
•ububanzi bokushisa okusebenzayo
•Ukumelana noketshezi namagesi
•Ukumelana nokushisa, i-ozone kanye nemisebe ye-UV
Ukukhethwa kwama-elastomer kusekelwe kakhulu ku:
•ububanzi bokushisa okusebenzayo
•Ukumelana noketshezi namagesi
•Ukumelana nokushisa, i-ozone kanye nemisebe ye-UV
Izinto eziyisithupha okumele zicatshangelwe lapho kukhethwa izinto zokuvala ivalvu
Indawo yokuvala iyindawo yokusebenza ebaluleke kakhuluivalvu, ikhwalithi yendawo yokuvala ithinta ngqo impilo yesevisi yeivalvu, futhi izinto zomphezulu wokuvala ziyisici esibalulekile ukuqinisekisa ikhwalithi yomphezulu wokuvala. Ngakho-ke, lezi zinto ezilandelayo kufanele zicatshangelwe lapho kukhethwa izinto zomphezulu wokuvala ivalvu:
①Ukumelana nokugqwala. “Ukugqwala” inqubo lapho ubuso bomphezulu wokuvala bonakaliswa khona ngaphansi kwesenzo sendawo. Uma ubuso bomphezulu wokuvala bugqwala, ukusebenza kokuvala akunakuqinisekiswa, ngakho-ke izinto zomphezulu wokuvala kumele zingagqwali. Ukumelana nokugqwala kwezinto kuncike kakhulu ekwakhiweni kwezinto kanye nokuqina kwazo kwamakhemikhali.
②Ukulwa nokuklwebheka. Igama elithi “Scratch” libhekisela emonakalweni obangelwa ukuklwebheka kwezinto ngesikhathi sokunyakaza okuhlobene kwendawo yokuvala. Lolu hlobo lomonakalo luzobangela umonakalo endaweni yokuvala. Ngakho-ke, izinto zokuvala kumele zibe nezakhiwo ezinhle zokulwa nokuklwebheka, ikakhulukazi kuma-valve esango. Ukumelana nokuklwebheka kwezinto kuvame ukunqunywa yizakhiwo zangaphakathi zezinto.
③Ukumelana nokuguguleka. “Ukuguguleka” inqubo yokubhubhisa indawo yokuvala lapho indawo igeleza endaweni yokuvala ngesivinini esikhulu. Lolu hlobo lomonakalo lubonakala kakhulu kuma-valve e-throttle nama-valve okuphepha asetshenziswa ezindaweni zokushisa okuphezulu kanye ne-high pressure steam media, futhi lunomthelela omkhulu ekulimaleni kokusebenza kokuvala. Ngakho-ke, ukumelana nokuguguleka nakho kungenye yezidingo ezibalulekile zokuvala izinto zokuvala.
④Kufanele ibe nobunzima obuthile, futhi ubulukhuni buzokwehla kakhulu ngaphansi kwezinga lokushisa lokusebenza elichaziwe.
⑤I-coefficient yokwandisa okuqondile kwendawo yokuvala kanye nezinto zomzimba kufanele kufane, okubaluleke kakhulu ekwakhiweni kwendandatho yokuvala, ukuze kugwenywe ukucindezeleka okwengeziwe kanye nokuxega ekushiseni okuphezulu.
⑥Uma isetshenziswa ngaphansi kwezimo zokushisa okuphezulu, kumele kube khona okwanele kokulwa ne-oxidation, ukumelana nokukhathala kokushisa kanye nezinkinga zomjikelezo wokushisa.
Ngaphansi kwezimo zamanje, kunzima ukuthola izinto zokuvala ezihlangabezana ngokugcwele nezidingo ezingenhla. Singagxila kuphela ekuhlangabezaneni nezidingo zezici ezithile ngokwezinhlobo ezahlukene zamavalvu kanye nokusetshenziswa kwawo. Isibonelo, amavalvu asetshenziswa ezindizeni ezisheshayo kufanele anake kakhulu izidingo zokumelana nokuguguleka kwendawo yokuvala; futhi uma indawo yokuvala iqukethe ukungcola okuqinile, izinto zokuvala ezinobunzima obukhulu kufanele zikhethwe.
