1. Isifinyezo
Ishubhu elingaphakathi liwumkhiqizo wenjoloba omncane omncane, futhi eminye imikhiqizo yemfucuza ikhiqizwa ngokungenakugwenywa ngesikhathi sokukhiqiza, engenakuqhathaniswa nesondo langaphandle, kodwaama-valveaphelele, futhi lawa mavalvu angagaywa kabusha futhi asetshenziswe kabusha ekukhiqizeni amashubhu angaphakathi. Inkampani yethu yenze ezinye izivivinyo zokugaywa kabusha nokusetshenziswa kabusha kwama-valve eshubhu yangaphakathi, kodwa izinga lokubukeka lama-valve agaywe kabusha liphansi, futhi amandla okubopha phakathi kwesisekelo se-valve ne-rubber pad aphansi, futhi adinga ukuphinda asetshenziswe ngaphambi kwalokho. ingasetshenziswa. .
Lo msebenzi uthuthukisa inqubo yokugaywa kabusha kwemfucuza kanye nama-valve amashubhu angaphakathi anesici ukuze kwehliswe imfucuza futhi kuthuthukiswe izinzuzo zezomnotho zamabhizinisi.
2. Ukuhlaziya Inkinga
Inqubo yokugaywa kabusha kukadoti wokuqala futhi inesiciama-valve amashubhu angaphakathiimi kanje: imfucumfucu kanye nama-valve amashubhu angaphakathi angenasici → ukushiswa → ukwelashwa kwe-asidi → ukuvuvuka kwemodi eyodwa (amaphedi okunamathela) → amabhristle kumaphedi enjoloba.
Izinkinga zalolu hlelo olubalwe ngenhla zimi kanje.
(1) Ukushiswa kwemfucuza kanye nama-valve amashubhu angaphakathi anesici kuzodala ukungcoliswa okukhulu kwemvelo. Umzimba we-valve osetshenziswe kabusha ukhubazeka kalula futhi ubonakala ungcolile. Kunzima ukuyihlanza ngesikhathi sokwelashwa kwe-asidi, futhi kulula ukubangela ukungcola kwezinye izinqubo.
(2) Ukuze kube lula ukukhishwa nokususwa kwe-valve, idizayini yokuqala yesikhunta se-vulcanization iyisikhunta esisodwa futhi ihlukaniswe izingxenye ezi-3. I-vulcanization yemodi eyodwa ithatha isikhathi eside, ukusebenza kahle okuphansi, umfutho wemisebenzi ephezulu kanye nokusetshenziswa kwamandla, kanti indawo engaphandle yevalvu evuvukele ijwayele ukuba nemicu yerabha engasasebenzi, irabha isonga umlomo womlomo, kanye nekhwalithi yokubukeka yevalvu. ayihlangabezani nezidingo. Amandla okunamathela wephedi yokunamathisela nawo awazinzile.
(3) I-bristling manual yephedi yenjoloba inezinkinga zokuqina okukhulu kwabasebenzi, ukusebenza kahle okuphansi, kanye nendawo engalingani, ethinta ukubopha kwephedi yenjoloba kanye nempahla yerabha yeshubhu elingaphakathi.
3 Umphumela wokuthuthukisa
Umfanekiso wesi-2 ubonisa umzimba we-nozzle otholwe ngaphambi nangemva kokuthuthukiswa kwenqubo yokulandela. Kungabonakala kuMfanekiso 2 ukuthi umzimba wombhobho olashwa ngenqubo ethuthukisiwe ngokusobala uhlanzekile, futhi nomzimba wombhobho ucishe uphelele. Ngenqubo ethuthukisiwe, inani le-asidi namanzi asetshenzisiwe lincane, futhi ukungcoliswa kwemvelo kuncane, futhi iphedi yenjoloba esikiwe ingagaywa kabusha ukuze kukhiqizwe irabha ebuyisiwe.
Ngaphambi kokuthuthukiswa, umphumela wokudlulisa ukushisa kwesikhunta awulungile, futhi i-vulcanization ithatha imizuzu engu-15. Ngokwezimo zokusebenza ze-vulcanizer eyisicaba ekhona, ama-valve angu-4 kuphela angavuthwa ngesikhathi, futhi ama-valve angaba ngu-16 angakhiqizwa ngehora, okungabandakanyi ukulayishwa kwesikhunta. isikhathi. Ngesikhunta esihlanganisiwe esilungisiwe, kuthatha imizuzu emi-5 kuphela ukuvuvukala, ama-valve angama-25 angavulwa isikhathi ngasinye, futhi amavalvu angaba ngu-300 angakhiqizwa ngehora. Kulula ukuyifaka nokuyicisha, futhi amandla okusebenza aphansi.
Ngomshini oguquliwe wesikhunta kanye nomshini wokuqothula, kokubili ama-valve aqondile nama-valve agobile angakhiqizwa, futhi izimo zenqubo ziyafana. Awukho umehluko osobala ekubukekeni naseqophelweni langaphakathi phakathi kwamavalvu agaywe kabusha futhi asetshenziswa kabusha inqubo ethuthukisiwe namavalvu amasha. Imiphumela yokuhlolwa ibonisa ukuthi isilinganiso samandla okubopha phakathi kwesisekelo se-valve kanye nephedi yenjoloba egaywe kabusha ngenqubo ethuthukisiwe ngu-12.8 kN m-1, kuyilapho isilinganiso samandla okubopha phakathi kwesisekelo se-valve entsha nephedi yenjoloba ingu-12.9 kN m-1, Izindinganiso zebhizinisi zidinga ukuthi amandla okubopha angabi ngaphansi kuka-7 kN·m-1.
Ngemva kweminyaka engaphezu kweshumi yentuthuko esheshayo, imboni yama-valve yaseChina isibuse umhlaba wonke. Njengamanje, ukukhiqizwa kwama-valve ezwe lami kwenza ngaphezu kuka-70% wengqikithi yokukhiqizwa kwama-valve emhlabeni, ikleliswe kuqala ekukhiqizweni nasekuthengisweni kwamavalvu emhlabeni. Ukuze kuhlangatshezwane nezidingo zezimakethe zasekhaya nezamazwe ngamazwe, izinga le-tubeless lama-valve liye landa kancane kancane. Ngo-2015, ukukhishwa kwama-valve angenawo ama-tubeless kuye kwaba ngaphezu kwengxenye yokukhishwa okuphelele kwama-valve. Isidingo esikhulu semakethe yasekhaya sihlala sikhuthaza ukuthuthukiswa kwemboni.
Isidingo semakethe yama-valve sihlukaniswe ikakhulukazi imakethe ye-OEM kanye nemakethe ye-AM. Idatha yakamuva ibonisa ukuthi i-valve yomoya iyingxenye ebalulekile yokuphepha yemojuli yesondo lemoto. Ngenxa yokuthi sekunesikhathi eside ivezwe ngaphandle, idinga ukumelana nokuguguleka kwemvelo okuhlukahlukene. Amavavu ngokuvamile ashintshwa ngesikhathi sokuhlolwa kwaminyaka yonke nokushintshwa kwamathayi, ngakho isidingo samavalvu emakethe ye-AM siphezulu kakhulu kunaleso esisemakethe ye-OEM.
4. I-Epilogue
Ngobuchwepheshe obuthuthukisiwe, inqobo nje uma umzimba we-valve ungakhubazekile, ungaphinda usetshenziswe. Izinga lama-valve omoya asetshenziswe kabusha lihlangabezana nezidingo zokusetshenziswa, ezinganciphisa ukusetshenziswa kwezinto ezingavuthiwe namandla, kunciphise izindleko zokukhiqiza amashubhu angaphakathi, futhi kuthuthukise izinzuzo zezomnotho zamabhizinisi.
