Izimpawu zephampu likaphethiloli eliphukile.
Imbangela yokwehluleka kwepompo likaphethiloli wezimoto.
Izizathu zokwehluleka kwepompo likaphethiloli wemoto ikakhulukazi zifaka amaphuzu alandelayo:
Inkinga yekhwalithi kaphethiloli : ukusetshenziswa kokungcola okusezingeni eliphansi noma ngaphezulu kuzonciphisa impilo yephampu kawoyela, okuholela ekulimaleni kwepompo likawoyela.
Isihlungi sikaphethiloli asizange sithathelwe indawo isikhathi eside : uhlelo lokunikezwa kukawoyela wesihlungi sikaphethiloli luvinjwe kakhulu, luthinta iphampu kawoyela, ukuze iphampu kawoyela ibe ngaphansi komthwalo isikhathi eside, okuholela ekulimaleni.
ukwehluleka komshini : okufana nokulimala kwevalvu yephampu likaphethiloli, ukuguga kwempompi ye-centrifugal, ukunamathela kwe-rotor, njll. Lokhu kwehluleka kwemishini kuzophazamisa ukunikezwa kukaphethiloli, okuholela ekutheni iphampu kawoyela ingakwazi ukusebenza ngendlela evamile.
Isixazululo sokuhluleka kwepompo likaphethiloli wezimoto
Ngokuhluleka kwephampu yemoto kaphethiloli, lezi zixazululo ezilandelayo zingathathwa:
Shintsha isihlungi sikaphethiloli : Hlola bese ufaka isihlungi sikaphethiloli njalo ukuze uqinisekise ukuthi uhlelo lokuphakela uphethiloli aluphazamiseki.
Ukusetshenziswa kukaphethiloli wekhwalithi ephezulu : Khetha uphethiloli othembekile wekhwalithi, gwema ukusetshenziswa kokungcola okwengeziwe kukaphethiloli.
Bheka bese ushintsha iphampu kaphethiloli : uma iphampu kaphethiloli inamaphutha angathi sína, njengokulimala kwevalvu yokuhlola, ukugqokwa kwe-impeller, njll., kuyadingeka ukuhlola nokufaka esikhundleni sephampu kaphethiloli ngesikhathi.
ukulungisa noma ukushintsha izingxenye ezihlobene : ezinkingeni zephampu kawoyela ezibangelwa ukwehluleka komshini, njengokunamathela kwe-rotor, isidingo sokukhanda noma ukushintsha izingxenye ezihlobene.
Ukufingqa, ukugcinwa okuvamile nokuhlolwa kwesistimu yamafutha emoto, ukusetshenziswa kwephethiloli yekhwalithi ephezulu, kuyisinyathelo esibalulekile sokuvimbela ukwehluleka kwepompo likaphethiloli. Uma iphampu kaphethiloli itholakala ukuthi inezimpawu zephutha, kufanele ihlolwe futhi ilungiswe ngesikhathi ukuze kuqinisekiswe ukusebenza okuvamile kwemoto.
Yiziphi izimpawu zokucindezela kwepompo ye-petroli enganele
01 Ukusheshisa kwemoto akunamandla
Ukusheshisa imoto buthaka, ikakhulukazi ukusheshisa ngokushesha izovela ukukhungatheka. Lesi sibonakaliso ngokuvamile sibangelwa ukucindezela okunganele empompini kaphethiloli. Uma iphampu kaphethiloli inganikezi umfutho wephethiloli owanele, injini iyathinteka uma idinga amandla engeziwe, okuholela ekuzweni okumayo lapho ishesha. Lokhu akuthinti nje kuphela ulwazi lokushayela, kodwa kungase kuthinte kabi ukusebenza nokuphepha kwemoto. Ngakho-ke, uma lesi sibonakaliso sitholakala, ipompo likaphethiloli kufanele lihlolwe futhi lilungiswe ngesikhathi.
02 Isibani sokuhluleka kwenjini sensimbi yokuhlanganiswa kwemoto sivutha njalo
Isibani sokwehluleka kwenjini ensimbini yokuhlanganiswa kwemoto kuwuphawu olucacile lokucindezela kwepompo likaphethiloli okunganele. Iphampu kaphethiloli idlala indima ebalulekile ohlelweni lokuphakela uphethiloli lwenjini, olubhekele ukudonsa uphethiloli ethangini bese liwuhambisa enjinini ngomfutho othile. Lapho ingcindezi yepompo likaphethiloli ingaphansi kwebanga elijwayelekile, imoto izoxwayisa umshayeli ngokukhanya kokuhluleka kwenjini. Umfutho ojwayelekile kaphethiloli kufanele ube ngu-0.3MPa uma inkinobho yokushisa ivuliwe kodwa injini ingakaqalwa, futhi ingcindezi kufanele ibe ngu-0.25MPa lapho injini iqalwa futhi ingenzi lutho. Ngakho-ke, lapho ukukhanya kokwehluleka kwenjini kuqhubeka nokukhanya, kufanele uhlole ukuthi ingcindezi yepompo likaphethiloli ijwayelekile.
03 Ubunzima bokuqalisa
Ubunzima bokuqala kuwuphawu olucacile lokucindezela okunganele kupompo likaphethiloli. Lapho ukucindezela kwepompo likaphethiloli kunganele, imoto ingase ihlangabezane nobunzima lapho iqala, okubonakala njengokubambezeleka kokuqala imoto. Lesi simo esinzima sokuqala ngokuvamile sihlobene nokucindezela kwepompo likaphethiloli, ngoba ukuntuleka kokucindezela kungaholela ekuntuleni ukunikezwa kwamafutha, okuthinta ukuqala okuvamile kwenjini.
