1. Isishwankathelo
Umbhobho wangaphakathi yimveliso yerabha ebhityileyo, kwaye ezinye iimveliso zenkunkuma ziveliswa ngokungenakuphepheka ngexesha lenkqubo yokuvelisa, ezingenakulinganiswa netayara langaphandle, kodwaiivalvuazinazo zonke, kwaye ezi valves zingaphinda zisetyenziswe kwaye zisetyenziswe kwakhona kwimveliso yeetyhubhu zangaphakathi. Inkampani yethu yenze uvavanyo oluthile malunga nokurisayikilisha kunye nokusetyenziswa kwakhona kweevalvu zeetyhubhu zangaphakathi, kodwa umgangatho weevalvu ezirisayikilishiweyo awulunganga, kwaye amandla okubopha phakathi kwesiseko sevalvu kunye nephedi yerabha aphantsi, kwaye kufuneka isetyenziswe kwakhona ngaphambi kokuba isetyenziswe.
Lo msebenzi uphucula inkqubo yokusetyenziswa kwakhona kwenkunkuma kunye neevalvu zetyhubhu yangaphakathi ezineziphene ukuze kuncitshiswe inkunkuma kwaye kuphuculwe iingenelo zoqoqosho zamashishini.
2. Uhlalutyo lweengxaki
Inkqubo yokusetyenziswa kwakhona kwenkunkuma yokuqala kunye nenkunkuma enezipheneiivalvu zetyhubhu yangaphakathingolu hlobo lulandelayo: inkunkuma kunye neevalvu zetyhubhu yangaphakathi ezineziphene → ukutshiswa → unyango lwe-asidi → i-vulcanization yendlela enye (ii-adhesive pads) → iibristles kwii-raber pads.
Iingxaki zenkqubo ekhankanyiweyo apha ngasentla zezi zilandelayo.
(1) Ukutshiswa kwenkunkuma kunye neevalvu zetyhubhu yangaphakathi ezineziphene kuya kubangela ungcoliseko olukhulu lokusingqongileyo. Umzimba wevalvu ephinda isetyenziswe uyaguquguquka lula kwaye unembonakalo engcolileyo. Kunzima ukuyicoca ngexesha lonyango lwe-asidi, kwaye kulula ukubangela ungcoliseko kwezinye iinkqubo.
(2) Ukuze kube lula ukususwa nokususwa kwevalvu, uyilo lokuqala lwesikhunta se-vulcanization luyisikhunta esinye kwaye lwahlulwe lwaba ngamacandelo ama-3. I-vulcanization yendlela enye ithatha ixesha elide, ukusebenza kakuhle okuphantsi, amandla aphezulu okusebenza kunye nokusetyenziswa kwamandla, kwaye umphezulu wangaphandle wevalvu e-vulcanized uthambekele kwimigca yerabha engafunekiyo, irabha isonga umlomo womlomo, kwaye umgangatho wembonakalo yevalvu awuhlangabezani neemfuno. Amandla okuncamathela kwiphedi yokuncamathelisa nawo awazinzile.
(3) Ukuqhoboshelwa ngesandla kwephedi yerabha kuneengxaki zobunzima bokusebenza kakhulu, ukusebenza kakuhle okuphantsi, kunye nomphezulu wokuqhoboshelwa ongalinganiyo, nto leyo echaphazela ukubopha kwephedi yerabha kunye nezinto zerabha zetyhubhu yangaphakathi.
3 Isiphumo sokuphucula
Umfanekiso 2 ubonisa umzimba we-nozzle obuyiselweyo ngaphambi nasemva kokuphuculwa kwenkqubo elandelayo. Kuyabonakala kuMfanekiso 2 ukuba umzimba we-nozzle ophathwe yinkqubo ephuculweyo ngokucacileyo ucocekile, kwaye umzimba we-nozzle phantse uphelele. Ngenkqubo ephuculweyo, ubungakanani be-asidi namanzi asetyenzisiweyo buncinci, kwaye ungcoliseko lokusingqongileyo luncinci, kwaye i-rubber pad esikiweyo inokuphinda isetyenziswe ukuvelisa irabha ebuyiselweyo.
Ngaphambi kokuba kuphuculwe, isiphumo sokudlulisa ubushushu besikhunta asibi sihle, kwaye i-vulcanization ithatha imizuzu eli-15. Ngokweemeko zokusebenza ze-flat vulcanizer ekhoyo, zi-valve ezi-4 kuphela ezinokuvundiswa ngexesha, kwaye zi-valve ezili-16 ezinokwenziwa ngeyure, ezingabandakanyi ixesha lokulayisha isikhunta. Ngesikhunta esidibeneyo esiguquliweyo, kuthatha imizuzu emi-5 kuphela ukuvundisa, ii-valve ezingama-25 zinokuvundiswa ngalo lonke ixesha, kwaye zi-valve ezingama-300 ezinokwenziwa ngeyure. Kulula ukuyifaka nokubonisa, kwaye amandla okusebenza aphantsi.
Ngomatshini wokubumba nowokususa inkunkuma oguquliweyo, zombini iivalvu ezithe tye kunye neevalvu ezigobileyo zinokwenziwa, kwaye iimeko zenkqubo ziyafana. Akukho mahluko ucacileyo kwimbonakalo kunye nomgangatho wangaphakathi phakathi kweevalvu eziphinda zisetyenziswe kwaye zisetyenziswe yinkqubo ephuculweyo kunye neevalvu ezintsha. Iziphumo zovavanyo zibonisa ukuba amandla aphakathi okubopha phakathi kwesiseko sevalvu kunye nephedi yerabha ephinda isetyenzisiwe yinkqubo ephuculweyo yi-12.8 kN m-1, ngelixa amandla aphakathi okubopha phakathi kwesiseko sevalvu entsha kunye nephedi yerabha yi-12.9 kN m-1, imigangatho yeShishini ifuna ukuba amandla okubopha angabi ngaphantsi kwe-7 kN·m-1.
Emva kweminyaka engaphezu kweshumi yophuhliso olukhawulezileyo, ishishini leevalvu laseTshayina lilawula ihlabathi. Okwangoku, imveliso yeevalvu zelizwe lam ibandakanya ngaphezulu kwe-70% yemveliso iyonke yeevalvu zehlabathi, ibekwe kwindawo yokuqala kwimveliso nakwintengiso yeevalvu zehlabathi. Ukuze kuhlangatyezwane neemfuno zeemarike zasekhaya nezamazwe ngamazwe, izinga leevalvu ezingenazityhubhu liye landa kancinci kancinci. Ngo-2015, imveliso yeevalvu ezingenazityhubhu ibangele ngaphezulu kwesiqingatha semveliso iyonke yeevalvu. Imfuno enkulu yemarike yasekhaya ikhuthaza rhoqo uphuhliso lweshishini.
Imfuno yemarike yeevalvu yahlulwe ngokubanzi kwiimarike ze-OEM kunye neemarike ze-AM. Idatha yamva nje ibonisa ukuba ivalvu yomoya yinxalenye ebalulekileyo yokhuseleko kwimodyuli yamavili emoto. Ngenxa yokuba ivele ngaphandle ixesha elide, kufuneka imelane nokukhukuliseka okunzima kokusingqongileyo. Iivalvu zihlala zitshintshwa ngexesha lokuhlolwa konyaka kunye nokutshintshwa kwamatayara, ngoko ke imfuno yeevalvu kwimarike ye-AM iphezulu kakhulu kunaleyo kwimarike ye-OEM.
4. Isiphelo
Ngobuchwepheshe obuphuculweyo, lo gama nje umzimba wevalvu ungaguquguquki, ungaphinda usetyenziswe. Umgangatho weevalvu zomoya eziphinda zisetyenziswe uyahlangabezana neemfuno zokusetyenziswa, nto leyo enokunciphisa ukusetyenziswa kwezinto ezikrwada kunye namandla, inciphise iindleko zokuvelisa iityhubhu zangaphakathi, kwaye iphucule iingenelo zoqoqosho zamashishini.
