1. Isifinyezo
Ipayipi elingaphakathi liwumkhiqizo werabha omncane, futhi eminye imikhiqizo engcolile ikhiqizwa ngokungenakugwenywa ngesikhathi senqubo yokukhiqiza, engenakufaniswa nethayi elingaphandle, kodwaamavalvuaphelele, futhi lawa ma-valve angaphinde asetshenziswe futhi asetshenziswe ekukhiqizweni kwe-inner tube. Inkampani yethu yenze izivivinyo ezithile mayelana nokusetshenziswa kabusha kwama-inner tube valve, kodwa ikhwalithi yokubukeka kwama-inner tube valve ayinhle, futhi amandla okubopha phakathi kwesisekelo se-valve kanye ne-raber pad aphansi, futhi kudingeka asetshenziswe kabusha ngaphambi kokuba asetshenziswe.
Lo msebenzi uthuthukisa inqubo yokuvuselela imfucuza kanye nama-valve epayipi angaphakathi anephutha ukuze kuncishiswe imfucuza futhi kuthuthukiswe izinzuzo zezomnotho zamabhizinisi.
2. Ukuhlaziywa Kwezinkinga
Inqubo yokuvuselela kabusha imfucuza yokuqala kanye nemfucuza enesiciamavalvu epayipi langaphakathikungokulandelayo: ama-valve epayipi langaphakathi angcolile nanephutha → ukushiswa → ukwelashwa nge-asidi → i-vulcanization yemodi eyodwa (ama-pads okunamathelayo) → ama-bristle kuma-pads enjoloba.
Izinkinga zenqubo eshiwo ngenhla yilezi ezilandelayo.
(1) Ukushiswa kwemfucuza kanye nama-valve epayipi langaphakathi anephutha kuzobangela ukungcola okukhulu kwemvelo. Umzimba we-valve osetshenzisiwe uyaguquguquka kalula futhi ubukeka ungcolile. Kunzima ukuwuhlanza ngesikhathi sokwelashwa nge-asidi, futhi kulula ukubangela ukungcola kwezinye izinqubo.
(2) Ukuze kube lula ukususwa nokususwa kwevalvu, umklamo wokuqala wesikhunta se-vulcanization uyisikhunta esisodwa futhi uhlukaniswe izingxenye ezintathu. I-vulcanization yemodi eyodwa ithatha isikhathi eside, ukusebenza kahle okuphansi, amandla aphezulu okusebenza kanye nokusetshenziswa kwamandla, kanti ubuso bangaphandle bevalvu e-vulcanized buvame ukuba nemichilo yerabha engafuneki, irabha igoqa umlomo womlomo, futhi ikhwalithi yokubukeka kwevalvu ayihlangabezani nezidingo. Amandla okunamathela ephedi yokunamathela nawo awazinzile.
(3) Ukugoba ngesandla kwephedi yerabha kunezinkinga zokuqina komsebenzi okuphezulu, ukusebenza kahle okuphansi, kanye nobuso obungalingani bokugoba, okuthinta ukubopha kwephedi yerabha kanye nezinto zerabha zepayipi langaphakathi.
3 Umphumela wokuthuthukisa
Isithombe 2 sibonisa umzimba we-nozzle obuyiselwe ngaphambi nangemva kokuthuthukiswa kwenqubo elandelayo. Kungabonakala ku-Figure 2 ukuthi umzimba we-nozzle ophathwe yinqubo ethuthukisiwe uhlanzekile ngokusobala, futhi umzimba we-nozzle cishe awusaphelele. Ngenqubo ethuthukisiwe, inani le-asidi namanzi asetshenziswayo lincane, kanti ukungcola kwemvelo kuncane, futhi iphedi yerabha esikiwe ingaphinde isetshenziswe ukuze kukhiqizwe irabha ebuyiselwe.
Ngaphambi kokuthuthukiswa, umphumela wokudlulisa ukushisa kwesikhunta awubi muhle, futhi i-vulcanization ithatha imizuzu eyi-15. Ngokwezimo zokusebenza ze-flat vulcanizer ekhona, ama-valve ama-4 kuphela angavulwa ngesikhathi, futhi ama-valve angaba ngu-16 angakhiqizwa ngehora, okungafaki isikhathi sokulayisha isikhunta. Ngesikhunta esihlanganisiwe esiguquliwe, kuthatha imizuzu emi-5 kuphela uvulwa, ama-valve angama-25 angavulwa isikhathi ngasinye, futhi ama-valve angaba ngu-300 angakhiqizwa ngehora. Kulula ukuyifaka nokukhipha, futhi amandla okusebenza aphansi.
Ngomshini wokubumba nokususa imfucuza oguquliwe, ama-valve aqondile nama-valve agobile angakhiqizwa, futhi izimo zenqubo ziyafana. Akukho mehluko osobala ekubukekeni kanye nekhwalithi yangaphakathi phakathi kwama-valve aphinde asetshenziswe futhi asetshenziswa kabusha yinqubo ethuthukisiwe kanye nama-valve amasha. Imiphumela yokuhlola ikhombisa ukuthi amandla okubopha aphakathi kwesisekelo se-valve kanye nephedi yerabha aphinde asetshenziswa yinqubo ethuthukisiwe angu-12.8 kN m-1, kuyilapho amandla okubopha aphakathi kwesisekelo se-valve entsha kanye nephedi yerabha angu-12.9 kN m-1, Izindinganiso zebhizinisi zidinga ukuthi amandla okubopha angaphansi kuka-7 kN·m-1.
Ngemva kweminyaka engaphezu kweyishumi yentuthuko esheshayo, imboni yama-valve yaseShayina ibuse umhlaba wonke. Njengamanje, ukukhiqizwa kwama-valve ezweni lami kungaphezu kwama-70% okukhiqizwa kwama-valve emhlabeni wonke, okubekwe endaweni yokuqala ekukhiqizweni nasekuthengisweni kwama-valve emhlabeni. Ukuze kuhlangatshezwane nezidingo zezimakethe zasekhaya nezamazwe ngamazwe, izinga lama-valve angenama-tube liye landa kancane kancane. Ngo-2015, ukukhiqizwa kwama-valve angenama-tube kuye kwaba ngaphezu kwengxenye yokukhiqizwa kwama-valve. Isidingo esikhulu semakethe yasekhaya sikhuthaza njalo intuthuko yemboni.
Isidingo semakethe yamavalvu sihlukaniswe kakhulu emakethe ye-OEM kanye nemakethe ye-AM. Idatha yakamuva ikhombisa ukuthi ivalvu yomoya iyingxenye ebalulekile yokuphepha kwemojuli yamasondo emoto. Ngenxa yokuthi ibilokhu ivezwa ngaphandle isikhathi eside, idinga ukumelana nokuguguleka kwemvelo okuhlukahlukene okunzima. Amavalvu ngokuvamile ashintshwa ngesikhathi sokuhlolwa kwaminyaka yonke kanye nokushintsha amathayi, ngakho-ke isidingo samavalvu emakethe ye-AM siphezulu kakhulu kunesemakethe ye-OEM.
4. Isiphetho
Ngobuchwepheshe obuthuthukisiwe, inqobo nje uma umzimba wevalvu ungaguquguquki, ungaphinde usetshenziswe. Ikhwalithi yamavalvu omoya aphinde asetshenziswa ihlangabezana nezidingo zokusetshenziswa, okunganciphisa ukusetshenziswa kwezinto zokusetshenziswa namandla, kunciphise izindleko zokukhiqiza amashubhu angaphakathi, futhi kuthuthukise izinzuzo zomnotho zamabhizinisi.
