Indlela Yokukhethwa Kwempompo Yamanzi
Ukugeleza kwephampu, okungukuthi, okukhipha amanzi, ngokuvamile akufanelekile ukukhetha okuningi, ngaphandle kwalokho kuzonyusa izindleko zokuthenga ipompo. Kufanele kukhethwe ngokuya ngesidingo, njengephampu yokuzikhandla esetshenziswa ngumndeni womsebenzisi, ukugeleza kufanele kukhethwe okuncane ngangokunokwenzeka; Uma umsebenzisi esebenzisa iphampu ebonakalayo yokunisela, kungafaneleka ukukhetha isilinganiso sokugeleza esikhudlwana.
1, ukuthenga amaphampu wamanzi ngokuya ngezimo zasendaweni. Kunezinhlobo ezintathu zamaphampu wezolimo asetshenziswa kakhulu, okungukuthi amaphampu we-centrifugal, amaphampu we-axial flow namaphampu okuxubile. Iphampu yeCentrifugal inekhanda eliphakeme, kepha ukuphuma kwamanzi, okulungele izindawo ezinezintaba kanye nezindawo zokunisela kahle. Iphampu ye-Axial Flow Pump inomphumela wamanzi amakhulu, kepha ikhanda aliphezulu kakhulu, elilungele ukusetshenziswa endaweni ethambile. Isivuno samanzi kanye nenhloko yephampu exutshwe phakathi kwephampu ye-centrifugal kanye ne-axial flow pump, futhi kufanelekile ukusetshenziswa ezindaweni ezicacile nezinamagquma. Abasebenzisi kufanele bakhethe futhi bathenge ngokwesimo somhlaba, umthombo wamanzi nokuphakama kwamanzi.
2, ukudlula kahle ukukhethwa kwepompo yamanzi. Ngemuva kokuthola uhlobo lwepompo, kuyadingeka ukubheka ukusebenza kwalo kwezomnotho, futhi unake ngokukhethekile ukukhethwa kwekhanda nokugeleza kwephampu namandla ayo asekelayo. Kumele kwaziwe ukuthi kunomehluko phakathi kokuphakanyiswa (okuphelele) okukhonjiswe kwilebula yephampu nokukhishwa kwe-lift (ukukhuphuka kwangempela) lapho kusetshenziswa ipayipi lokuphikiswa kwamanzi futhi eduze nepayipi. Ngakho-ke, inhloko yangempela imvamisa i-10% -20% ephansi kunekhanda eliphelele, futhi ukuphuma kwamanzi kuncishiswe ngokulandelana. Ngakho-ke, ekusetshenzisweni kwangempela, kuphela ngokuya ngophawu lwe-80% ~ 90% lokulinganisa kwekhanda nokugeleza, kungakhethwa ngokuphepha kwamandla okukhombisa, ngokuvamile kungaphezulu kwamandla adingekayo wepompo, ngokuvamile acishe abe ngu-10% ngaphezulu kufanele; Uma kukhona amandla, lapho uthenga iphampu yamanzi, ungakhetha iphampu ehambelana ngokusho kwamandla enjini.
3, ukuze uthenge ngokuqinile iphampu. Lapho uthenga, kuyadingeka ukuhlola "izitifiketi ezintathu", okungukuthi, ilayisense yokukhuthaza imishini yezolimo, isitifiketi sokuhlola umkhiqizo, kanye nezitifiketi ezintathu kuphela ezingakugwema ukuthengwa kwemikhiqizo eqediwe nemikhiqizo ephansi.
Ukukhetha inombolo
1, ngokusebenza okujwayelekile kwephampu, ngokuvamile okukodwa, ngoba iphampu enkulu lilingana namaphampu amabili amancane asebenza ngokufana, kungcono ukukhetha impompo enkulu, kungcono ukukhetha okufanayo, ukugeleza kukhulu, ukugeleza kukhulu, ipompo ayikwazi ukukuthola lokhu ukugeleza.
2, Ngoba amaphampu amakhulu adinga ukuba nenani lokugcina elingama-50%, amaphampu amabili amancane angashintshwa ukuze asebenze, okubili okubekwe eceleni (okuphelele kwezine)
I-3, kwamanye amaphampu amakhulu, izidingo ezingama-70% zephampu zingasetshenziswa ekusebenzeni okuhambisanayo, ngaphandle kwephampu epawu, ekusolweni kwepompo, elinye iphampu lisenesibopho sokukhiqizwa kwezokuthutha.
I-4, yepompo edinga amahora angama-24 okusebenza okuqhubekayo, kufanele kusetshenziswe amaphampu amathathu, ukusebenza okukodwa, okubekwe eceleni, nokulungiswa okukodwa.
Hlukanisa phakathi kweqiniso futhi amanga
Okokuqala, ukufakwa komkhiqizo kwephampu okuqala noma abakhiqizi abasekelayo kuvame ukulinganiswa, ukubhala ngesandla kucacile futhi kujwayelekile, futhi kukhona amagama omkhiqizo anemininingwane, amagama efektri kanye nezinombolo zocingo; Ukupakishwa okujwayelekile kwezesekeli zomgunyathi kunzima, futhi ikheli lefekthri negama alicaci.
Okwesibili, indawo yokufundela amanzi efanelekayo ibushelelezi futhi isebenza kahle. Izingxenye ezibaluleke kakhulu, ziphezulu ngokunemba okusebenzayo, okuqinisa kakhulu ukuvezwa kokuvimbela ukugqwala kanye nokuvimbela ukukhulisa. Lapho uthenga, uma izingxenye zitholakala zinezindawo zokugqwala noma izingxenye zenjoloba ziqhekekile, zilahlekelwe yi-elasticity noma indawo yamaphephabhuku inemigqa yokusebenza ekhanyayo, akufanele ibe izingxenye zangempela.
Okwesithathu, ukubukeka kwamaphampu aphansi kwesinye isikhathi kuhle. Kodwa-ke, ngenxa yenqubo engeyona yokukhiqiza, kulula ukulimala, lapho uthenga, inqobo nje uma uhlangothi, ekhoneni nezinye izingxenye ezifihliwe zezesekeli, ungabona ikhwalithi yenqubo yezesekeli.
Okwesine, amanye amaphampu alungiswa kabusha izingxenye zemfucumfucu, khona-ke inqobo nje uma upende ongaphezulu wesekeli ungatholwa ngemuva kopende wakudala, iphampu enjalo ingcono ungasebenzisi.
Okwesihlanu, izingxenye ezithengiwe zifakwe emotweni, kuya ngokuthi kungaba futhi zinenhlanganisela enhle yezesekeli. Ngokuvamile, izingxenye zangempela zingavulelwa kahle emotweni, futhi kunzima ukubambisana ndawonye ndawonye ngenxa yenqubo engeyinhle nephutha elikhulu lokucubungula.
Okwesithupha, ukuze kuqinisekiswe ukuthi ubudlelwane bomhlangano wepompo bahlangabezana nezidingo zobuchwepheshe, ezinye izingxenye ezijwayelekile ziqoshwe ngamamaki omhlangano ukuqinisekisa ukufakwa okulungile kwezesekeli, uma kungekho maki noma uphawu olungafanele.
Okwesikhombisa, umhlangano wepompu ejwayelekile kanye nezakhi kumele zibe ziqinile ekuqinisekiseni ukulayishwa okubushelelezi nokusebenza okujwayelekile. Ezinye zezingxenye ezincane emhlanganweni zilahlekile, kulula ukuqala ukulayisha imoto ukuze zibangele ubunzima, izingxenye ezinjalo zingaba yizingxenye zomgunyathi.
Eyesishiyagalombili, ezinye izesekeli ezibalulekile, ikakhulukazi isigaba soMhlangano, ngokuvamile ngemiyalo, izitifiketi, ukuze ziqondise abasebenzisi ukufaka, ukusetshenziswa kanye nokulungiswa, umhlangano wokugcina, ngokuvamile ngeke kube nemiyalo yokufaka enemininingwane yokuqondisa lokhu.
UZhuo Meng Shanghai Auto Co, Ltd uzibophezele ekuthengiseni izingxenye ze-MG & Mauxs auto wamukelekile ukuthenga.
