Indlela yokukhetha iphampu yamanzi
Ukugeleza kwepompo, okungukuthi, ukuphuma kwamanzi, ngokuvamile akufanelekile ukukhetha kakhulu, ngaphandle kwalokho kuzokwandisa izindleko zokuthenga iphampu. Kufanele kukhethwe ngokuya ngesidingo, njengephampu yokuzenzela esetshenziswa umndeni womsebenzisi, ukugeleza kufanele kukhethwe kukuncane ngangokunokwenzeka; Uma umsebenzisi esebenzisa iphampu engaphansi kwamanzi ukunisela, kungaba kuhle ukukhetha izinga lokugeleza elikhudlwana.
1, ukuthenga amaphampu amanzi ngokwezimo zendawo. Kunezinhlobo ezintathu zamaphampu ezolimo asetshenziswa kakhulu, okungamaphampu asecentrifugal, amaphampu e-axial flow kanye namaphampu agelezayo axubile. Iphampu ye-centrifugal inekhanda eliphezulu, kodwa ukuphuma kwamanzi amancane, afanele izindawo zezintaba nezindawo zokuchelela kahle. Ipompo yokugeleza kwe-axial inomphumela omkhulu wamanzi, kodwa ikhanda aliphezulu kakhulu, elifanele ukusetshenziswa endaweni engenalutho. Isivuno samanzi kanye nenhloko yepompo yokugeleza okuxubile kuphakathi kwepompo ye-centrifugal kanye ne-axial flow pump, futhi kufanelekile ukusetshenziswa ezindaweni ezingenalutho nezingamagquma. Abasebenzisi kufanele bakhethe futhi bathenge ngokuya ngesimo somhlabathi, umthombo wamanzi nokuphakama kokuphakamisa amanzi.
2, ukweqa kahle ukukhethwa kwepompo yamanzi. Ngemuva kokunquma uhlobo lwepompo, kuyadingeka ukucabangela ukusebenza kwayo kwezomnotho, futhi unake ngokukhethekile ukukhethwa kwekhanda nokugeleza kwepompo kanye namandla asekelayo. Kumele kuqashelwe ukuthi kunomehluko phakathi kokuphakama (ingqikithi yokuphakamisa) ekhonjiswe kulebula yepompo kanye nokuphakanyiswa kokukhipha (i-lift yangempela) uma kusetshenziswa, okubangelwa ukuthi kunokulahlekelwa okuthile kokumelana lapho amanzi egeleza epayipini lokuphakela amanzi. futhi eduze kwepayipi. Ngakho-ke, ikhanda langempela ngokuvamile liphansi ngo-10% -20% kunekhanda eliphelele, futhi ukuphuma kwamanzi kuyancishiswa ngokufanayo. Ngakho-ke, ekusetshenzisweni kwangempela, kuphela ngokusho kwesibonakaliso se-80% ~ 90% yesilinganiso sekhanda nokugeleza, ukukhetha kwamandla okusekela iphampu, kungakhethwa ngokuvumelana namandla aboniswe kuphawu, ukuze wenze iphampu iqale. ngokushesha futhi usebenzise ukuphepha, amandla enjini angaba mkhulu kancane kunamandla adingekayo wepompo, ngokuvamile afaneleka ngo-10% aphezulu; Uma kukhona amandla, uma uthenga iphampu yamanzi, ungakhetha iphampu ehambisanayo ngokwamandla enjini.
3, ukuthenga ngokuqinile futha. Lapho uthenga, kuyadingeka ukuhlola "izitifiketi ezintathu", okungukuthi, ilayisense yokukhuthaza imishini yezolimo, ilayisense yokukhiqiza kanye nesitifiketi sokuhlola umkhiqizo, futhi izitifiketi ezintathu kuphela ezingagwema ukuthengwa kwemikhiqizo esusiwe kanye nemikhiqizo ephansi.
Ukukhetha inombolo
I-1, ekusebenzeni okujwayelekile kwepompo, ngokuvamile eyodwa kuphela, ngoba iphampu enkulu ilingana namaphampu amabili amancane asebenza ngokufana, (ebhekisela ekhanda elifanayo nokugeleza), ukusebenza kahle kwepompo enkulu kuphakeme kunaleyo iphampu encane, ngakho-ke ngokombono wokulondoloza amandla, kungcono ukukhetha iphampu enkulu, kunokuba amaphampu amabili amancane, kodwa esimweni sezimo ezilandelayo, amaphampu amabili angabhekwa ngokubambisana okufanayo: ukugeleza kukhulu, a iphampu ayikwazi ukufinyelela lokhu kugeleza.
2, kumaphampu amakhulu adinga ukuba nesilinganiso sokugodla esingu-50%, amaphampu amabili amancane angashintshwa ukuze asebenze, amabili okulinda (inani eliphelele lamane)
I-3, kwamanye amaphampu amakhulu, i-70% yezidingo zokugeleza kwepompo ingasetshenziswa ekusebenzeni okufanayo, ngaphandle kwepompo eyisipele, ekugcinweni kwepompo, enye ipompo isabhekene ne-70% yokukhiqiza ezokuthutha.
4, ngepompo edinga amahora angama-24 wokusebenza okuqhubekayo, amaphampu amathathu kufanele asetshenziswe, ukusebenza okukodwa, okubekwe eceleni, kanye nokugcinwa okukodwa.
Hlukanisa phakathi kweqiniso namanga
Okokuqala, ukupakishwa komkhiqizo wephampu yasekuqaleni noma abakhiqizi abasekelayo kuvame ukwenziwa ngendlela efanayo, ukubhala ngesandla kucacile futhi kujwayelekile, futhi kunamagama emikhiqizo enemininingwane, imininingwane namamodeli, izimpawu zokuthengisa ezibhalisiwe, amagama emboni, amakheli emboni kanye nezinombolo zocingo; Ukupakishwa okuvamile kwezisekeli zomgunyathi kulukhuni, futhi ikheli lemboni negama akucacile.
Okwesibili, indawo yepompo yamanzi efanelekile ibushelelezi futhi iwumsebenzi omuhle. Lapho izingxenye zibaluleke kakhulu, kukhuphuka ukunemba kokucubungula, kuqinile kakhulu ukugqwala kokupakishwa nokuvikela ukugqwala. Lapho uthenga, uma izingxenye zitholakala zinezindawo zokugqwala noma izingxenye zenjoloba eziqhekekile, ukunwebeka okulahlekile noma indawo yejenali inemigqa yokucubungula ekhanyayo, akufanele kube izingxenye zangempela.
Okwesithathu, ukubukeka kwamaphampu aphansi ngezinye izikhathi kuhle. Kodwa-ke, ngenxa yenqubo empofu yokukhiqiza, kulula ukulimaza, lapho uthenga, uma nje uhlangothi, ikona kanye nezinye izingxenye ezifihliwe zezesekeli, ungabona ikhwalithi yenqubo yezesekeli.
Okwesine, amanye amaphampu avuselelwe izingxenye zemfucuza, khona-ke inqobo nje uma upende ongaphezulu kwezesekeli lungatholakala ngemuva kopende oludala, ipompo elinjalo lingcono kakhulu ukuthi lingasebenzisi.
Okwesihlanu, izingxenye ezithengiwe zifakwe emotweni, kuye ngokuthi ingaba yini futhi inenhlanganisela enhle yezesekeli. Ngokuvamile, izingxenye zangempela zingalinganiswa kahle emotweni, futhi izingxenye eziphansi zinzima ukubambisana nomunye nomunye ngenxa yenqubo embi kanye nephutha elikhulu lokucubungula.
Okwesithupha, ukuze kuqinisekiswe ukuthi ubudlelwano bomhlangano wepompo buhlangabezana nezidingo zobuchwepheshe, ezinye izingxenye ezijwayelekile ziqoshwa amamaki omhlangano ukuze kuqinisekiswe ukufakwa okufanele kwezesekeli, uma kungekho uphawu noma uphawu olungacacile alukwazi ukubonakala, akunjalo. izesekeli ezifanelekayo.
Okwesikhombisa, umhlangano wephampu ojwayelekile kanye nezingxenye kumele ziqine ukuze kuqinisekiswe ukulayisha okushelelayo nokusebenza okuvamile. Ezinye zezingxenye ezincane emhlanganweni azikho, kulula ukuqala ukulayisha imoto ukuze kubangele ubunzima, izingxenye ezinjalo zingase zibe izingxenye zomgunyathi.
Okwesishiyagalombili, ezinye izesekeli ezibalulekile, ikakhulukazi ikilasi lokuhlanganisa, ngokuvamile ezinemiyalo, izitifiketi, ukuze kuqondiswe abasebenzisi ukuthi bafake, basebenzise futhi banakekele, ukuhlanganiswa komgunyathi ngokuvamile ngeke kube nemiyalelo yokufaka enemininingwane yokuqondisa lokhu.
UZhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS wamukelekile ukuzithenga.
