Nguwe olawula inqubo - sinikezela ngesistimu. Ngokuvumelana nalesi siqubulo, i-Graphite Materials ibikhiqiza imikhiqizo yekhwalithi ephezulu yokubunjwa kwe-powder metallurgy iminyaka eminingi. Ngezisombululo zesistimu yethu, uyazuza kuzo zonke izinzuzo zenqubo ye-sintering yezingxenye eziqedwe kancane neziqediwe.
Imininingwane Yomkhiqizo
PRODUCT Inzuzo
Lapho ubeka izingxenye zensimbi neze-ceramic zokwelashwa kwezinga lokushisa eliphezulu kumapuleti okushaja asuka ku-Graphite Materials, kubalulekile ukucabangela izidingo ezithile zenqubo ukuze kuqinisekiswe imiphumela emihle. Amapuleti okushaja ama-graphite anikezela ngenani lezinzuzo zale njongo, okufaka phakathi amajiyometri achazwe ngaphambilini azinza isendlalelo somkhiqizo futhi anciphise ukuchezuka komumo. Ukwengeza, ukusetshenziswa kokuthunyelwe ukupakisha amapuleti noma amashidi kunganikeza inqubo esebenza kahle kakhulu.
Ukuqala, izingxenye zensimbi neze-ceramic kufanele zihlelwe ngokucophelela kumapuleti wokushaja ngendlela evumela ukushisa okufanayo nokwelashwa. Amajometri angaphezulu achazwe ngaphambilini amapuleti okushaja angasiza ukuqinisekisa ukuthi izingxenye zimi ngokuphephile nokuthi ukushisa kusakazwa ngokulinganayo kuyo yonke inqubo. Lokhu kubaluleke kakhulu ekwelapheni okunezinga lokushisa eliphezulu, njengoba noma yikuphi ukushisa okungalingani noma ukungazinzi kusendlalelo lomkhiqizo kungaholela emiphumeleni engaphansi.
Ngokungeziwe ekubekweni kwezingxenye kumapuleti okushaja, ukusetshenziswa kwezigxobo ukupakisha amapuleti noma amashidi kungathuthukisa ukusebenza kahle kwenqubo. Ngokubeka amapuleti, izingxenye eziningi zingelashwa ngesikhathi esisodwa, ukwandisa ukusetshenziswa kwendawo etholakalayo futhi kunciphise isikhathi sokucubungula sonke. Lokhu kungaba yinzuzo ikakhulukazi ekukhiqizweni kwevolumu ephezulu noma lapho kusebenza ngenani elikhulu lezingxenye.
Ngaphezu kwalokho, ukusetshenziswa kokuthunyelwe kungasiza futhi ekwenzeni lula ukuphathwa nokuthuthwa kwamapuleti okushaja kanye nezingxenye, okwenza kube lula ukuwalayisha nokuwakhulula emishinini yokwelapha. Lokhu kungaba nomthelela ekusebenzeni kahle kwenqubo kanye nokuphepha, kanye nokunciphisa ingozi yokulimala ezingxenyeni ngesikhathi sokuphatha.
Sekukonke, inhlanganisela yamajiyometri achazwe ngaphambili angaphezulu kumapuleti okushaja kanye nokusetshenziswa kokuthunyelwe ukuze kunqwabelene kungathuthukisa kakhulu inqubo yokwelashwa kwezinga lokushisa eliphezulu yezingxenye zensimbi nezeceramic. Ngokucabangela ngokucophelela ukuma nokuhlelwa kwezingxenye, kanye nokusebenzisa izici zamapuleti okushaja, abakhiqizi bangakwazi ukuzuza imiphumela engaguquki futhi enokwethenjelwa ngenkathi bekhulisa ukusebenza kahle kwenqubo.
Imikhiqizo Ehlobene
Ngo-1985, i-Datong Locomotive Works yabona ukuthi izitimela zikagesi zaziyisiqondiso esibalulekile sokuthuthukiswa kwesitimela sesitimela saseChina kanye nemboni yamasheya esikhathini esizayo, futhi yabeka phambili umbono wokukhiqiza we-"Nanzhu (Zhuzhou Electric Locomotive Works) kanye ne-Datong Locomotive Works".
Isitimela sikagesi sohlobo 3 lwe-Shaoshan siyisizukulwane sesibili sezwe lami esithwala abantu abangu-6 kanye nesitimela sempahla. I-locomotive isebenzisa ukulungiswa kwegagasi eligcwele kohlobo lwebhuloho futhi ibona ukulawulwa kwe-voltage ebushelelezi elawulwa yisigaba se-thyristor. Isitimela sithatha isigaba esisodwa se-AC 25kV 50Hz voltage system futhi sinesivinini sokusebenza esiphezulu esingu-100km/h.
I-SS3B fixed heavy-duty electric locomotive iyisitimela esithwala impahla esingu-12-axle. Iqukethe izitimela ezimbili ezifanayo ezinama-axle angu-6 axhunywe i-coupler kanye ne-windshield. Lezi zingxenye ezimbili zifakwe izixhumi zesistimu kagesi ezinamandla kagesi, izintambo zokulawula, nokuvikela inethiwekhi. Amapayipi okulawula ulayini nomoya. Imoto yonke ingalawulwa ngendlela efanayo kunoma iyiphi i-cab. Isitimela sithatha i-single- phase power frequency system, i-voltage engu-25kV, i-AC-DC transmission, kanti isivinini esikhulu sokusebenza sesitimela singu-100km/h.
Isitimela sikagesi esithuthukisiwe i-Shaoshan 4 iyisitimela esithwala impahla esingu-8-axle. Isitimela siqukethe izitimela ezimbili ezifanayo ezinama-axle amane axhunywe i-coupler kanye ne-windshield. Lezi zindawo zokusebenzela ezimbili zifakwe izixhumi ezinamandla kagesi aphezulu, izintambo zokulawula ukuxhuma kabusha kanye namapayipi okulawula amabhuleki emoyeni. Imoto yonke ingalawulwa ngokuhambisanayo ukusuka kukhabhu yomshayeli yanoma iyiphi enye yezimoto. Izitimela ezimbili nazo zingahlukaniswa futhi zisetshenziswe ngokuzimela njengesitimela esinama-axle amane.
