Izimpawu zephampu kaphethiloli ephukile.
Imbangela yokwehluleka kwephampu kaphethiloli yemoto.
Izizathu zokwehluleka kwepompo likaphethiloli lemoto zifaka phakathi amaphuzu alandelayo:
Inkinga yekhwalithi kaphethiloli: ukusetshenziswa kokungcola okungaphansi kwezinga elifanele noma okungaphezulu kukaphethiloli kuzonciphisa impilo yephampu kaphethiloli, okuholela ekulimaleni kwephampu kaphethiloli.
Isihlungi sikaphethiloli asikaze sishintshwe isikhathi eside: uhlelo lokuhlinzeka ngophethiloli kawoyela wesihlungi sikaphethiloli luvinjiwe kakhulu, okuthinta ipompo kawoyela, kangangokuthi ipompo kawoyela ingaphansi komthwalo isikhathi eside, okuholela ekulimaleni.
ukwehluleka komshini: njengomonakalo wevalvu yokuhlola iphampu kaphethiloli, ukuguguleka kwe-impeller yephampu ye-centrifugal, ukubhajwa kwe-rotor, njll. Lokhu kwehluleka komshini kuzothinta ukunikezwa kukaphethiloli, okuholela ekutheni iphampu kawoyela ingasebenzi kahle.
Isixazululo sokwehluleka kwephampu kaphethiloli yemoto
Uma iphampu kaphethiloli yemoto ingasebenzi kahle, kungasetshenziswa izixazululo ezilandelayo:
Shintsha isihlungi sikaphethiloli: Hlola futhi ushintshe isihlungi sikaphethiloli njalo ukuqinisekisa ukuthi uhlelo lokuphakelwa kukaphethiloli aluphazamiseki.
Ukusetshenziswa kukaphethiloli osezingeni eliphezulu: Khetha uphethiloli osezingeni elithembekile, gwema ukusebenzisa ukungcola okwengeziwe kukaphethiloli.
Hlola futhi ushintshe iphampu kaphethiloli: uma iphampu kaphethiloli inamaphutha amakhulu, njengomonakalo wevalvu yokuhlola, ukuguguleka kwe-impeller, njll., kuyadingeka ukuhlola nokushintsha iphampu kaphethiloli ngesikhathi.
ukulungisa noma ukushintsha izingxenye ezihlobene : ngezinkinga zephampu kawoyela ezibangelwa ukwehluleka kwemishini, njengokubhajwa kwerotor, kudingeka ukulungisa noma ukushintsha izingxenye ezihlobene.
Ngamafuphi, ukulungiswa nokuhlolwa njalo kohlelo lukaphethiloli wemoto, ukusetshenziswa kukaphethiloli wekhwalithi ephezulu, kuyisinyathelo esibalulekile sokuvimbela ukungasebenzi kahle kwephampu kaphethiloli. Uma iphampu kaphethiloli itholakale inezimpawu zamaphutha, kufanele ihlolwe futhi ilungiswe ngesikhathi ukuqinisekisa ukusebenza okuvamile kwemoto.
Yiziphi izimpawu zokuntuleka komfutho wephampu kaphethiloli
01 Ukusheshisa imoto kubuthakathaka
Ukusheshisa imoto kubuthakathaka, ikakhulukazi uma ukusheshisa okusheshayo kuzovela ukukhungatheka. Lesi sibonakaliso sivame ukubangelwa ukucindezeleka okunganele empompini kaphethiloli. Uma ipompo kaphethiloli inganikezi umfutho owanele kaphethiloli, injini iyathinteka uma idinga amandla engeziwe, okuholela ekuzizweni kokuma lapho isheshisa. Lokhu akugcini nje ngokuphazamisa ulwazi lokushayela, kodwa futhi kungathinta kabi ukusebenza kwemoto nokuphepha kwayo. Ngakho-ke, uma lesi sibonakaliso sesitholakele, ipompo kaphethiloli kufanele ihlolwe futhi ilungiswe ngesikhathi.
02 Isibani sokwehluleka kwenjini sethuluzi lokuhlanganisa imoto sivuliwe ngokuqinile
Isibani sokwehluleka kwenjini emshinini wokuhlanganisa imoto siwuphawu olucacile lokuntuleka komfutho wephampu kaphethiloli. Iphampu kaphethiloli idlala indima ebalulekile ohlelweni lokuhlinzeka ngophethiloli lwenjini, olunesibopho sokukhipha uphethiloli ethangini bese luwuthutha luye enjinini ngengcindezi ethile. Uma ingcindezi yephampu kaphethiloli ingaphansi kwebanga elijwayelekile, imoto izoxwayisa umshayeli ngesibani sokwehluleka kwenjini. Ingcindezi evamile kaphethiloli kufanele ibe cishe yi-0.3MPa lapho iswishi yokushisa ivuliwe kodwa injini ingakaqali, futhi ingcindezi kufanele ibe cishe yi-0.25MPa lapho injini iqalwa futhi ingasebenzi. Ngakho-ke, lapho isibani sokwehluleka kwenjini siqhubeka nokukhanya, kufanele uhlole ukuthi ingcindezi yephampu kaphethiloli ijwayelekile yini.
03 Ubunzima Bokuqalisa
Ubunzima bokuqala buwuphawu olucacile lokucindezela okunganele empompini kaphethiloli. Uma ingcindezi yepomponi kaphethiloli inganele, imoto ingabhekana nobunzima lapho iqala, okubonakala ngokubambezeleka kokuqala imoto. Lesi simo esinzima sokuqala sivame ukuhlotshaniswa nengcindezi yepomponi kaphethiloli, ngoba ukuntuleka kwengcindezi kungaholela ekushodeni kokunikezwa kukaphethiloli, okuthinta ukuqala okuvamile kwenjini.
