Indlela yokukhetha impompo yamanzi
Ukuhamba kwempompo, oko kukuthi, ukuphuma kwamanzi, ngokuqhelekileyo akufanelekanga ukukhetha kakhulu, ngaphandle koko kuya kwandisa iindleko zokuthenga impompo. Kufuneka kukhethwe ngokwemfuno, njengempompo ye-self-priming esetyenziswa yintsapho yomsebenzisi, ukuhamba kufuneka kukhethwe njengento encinci; Ukuba umsebenzisi usebenzisa impompo engaphantsi kwamanzi ukunkcenkceshela, kunokufaneleka ukukhetha umlinganiselo omkhulu wokuhamba.
1, ukuthenga iimpompo zamanzi ngokweemeko zendawo. Zintathu iindidi zeempompo zezolimo ezisetyenziswa ngokuqhelekileyo, ezizezi, iimpompo ze-centrifugal, iimpompo ze-axial flow kunye neempompo ezixutyiweyo. Impompo ye-centrifugal inentloko ephezulu, kodwa imveliso encinci yamanzi, efanelekileyo kwiindawo zeentaba kunye neendawo zokunkcenkceshela kakuhle. Ipompo yokuhamba kwe-axial inemveliso enkulu yamanzi, kodwa intloko ayiphezulu kakhulu, ifanelekile ukusetyenziswa kwindawo ecacileyo. Imveliso yamanzi kunye nentloko yepompo edibeneyo yokuhamba iphakathi kwempompo ye-centrifugal kunye ne-axial flow pump, kwaye ifanelekile ukusetyenziswa kwiindawo ezicacileyo kunye neenduli. Abasebenzisi kufuneka bakhethe kwaye bathenge ngokwemeko yomhlaba, umthombo wamanzi kunye nokuphakama kwamanzi.
2, ukugqithisa ngokufanelekileyo ukhetho lwempompo yamanzi. Emva kokumisela uhlobo lwempompo, kuyimfuneko ukuqwalasela ukusebenza kwayo kwezoqoqosho, kwaye ubeke ingqalelo ekhethekileyo ekukhethweni kwentloko kunye nokuhamba kwempompo kunye namandla ayo axhasayo. Kufuneka kuqatshelwe ukuba kukho umahluko phakathi kokunyuswa (ukunyuswa okupheleleyo) okubonakaliswe kwileyibhile yempompo kunye nokunyuswa kokukhupha (ukunyuswa kwangempela) xa kusetyenziswa, oko kungenxa yokuba kukho ilahleko ethile yokuxhathisa xa amanzi ehamba ngombhobho wonikezelo lwamanzi. kwaye kufuphi nombhobho. Ngoko ke, intloko yangempela i-10% -20% ephantsi kunentloko epheleleyo, kwaye imveliso yamanzi iyancitshiswa ngokufanayo. Ngoko ke, ekusebenziseni okwenyani, kuphela ngokuhambelana nomqondiso we-80% ~ 90% yentloko kunye noqikelelo lokuhamba, ukhetho lwempompo yokuxhasa amandla, lunokukhethwa ngokwamandla aboniswe kwisibonakaliso, ukwenzela ukuba impompo iqale. ngokukhawuleza kwaye usebenzise ukhuseleko, amandla e-injini anokuba mkhulu kancinane kunamandla afunekayo empompo, ngokubanzi malunga ne-10% ephezulu ifanelekile; Ukuba kukho amandla, xa uthenga ipompo yamanzi, unokukhetha ipompo ehambelanayo ngokwamandla enjini.
3, ukuthenga ngokungqongqo impompo. Xa kuthengwa, kuyimfuneko ukuhlola "izatifikethi ezintathu", oko kukuthi, ilayisenisi yokukhuthaza oomatshini bezolimo, ilayisenisi yokuvelisa kunye nesatifikethi sokuhlola imveliso, kwaye kuphela izatifikethi ezintathu ezinokuthi ziphephe ukuthengwa kweemveliso ezicinyiweyo kunye neemveliso eziphantsi.
Ukukhetha inani
I-1, ekusebenzeni okuqhelekileyo kwempompo, ngokuqhelekileyo inye kuphela, kuba impompo enkulu ilingana neempompo ezimbini ezincinci ezisebenza ngokufanayo, (ngokubhekiselele kwintloko efanayo kunye nokuhamba), ukusebenza kakuhle kwempompo enkulu kuphezulu kunompompo. impompo encinci, ngoko ke ngokombono wokulondoloza amandla, kungcono ukhethe impompo enkulu, kunokuba iimpompo ezimbini ezincinci, kodwa kwimeko yezi meko zilandelayo, iimpompo ezimbini zinokuqwalaselwa ngokubambisana okufanayo: ukuhamba kukhulu, a impompo ayikwazi ukufikelela koku kuhamba.
I-2, kwiimpompo ezinkulu ezifuna ukuba ne-50% yezinga lokugcina, iimpompo ezimbini ezincinci zingatshintshwa ukuba zisebenze, ezimbini zokulinda (zine zizonke)
I-3, kwezinye iimpompo ezinkulu, i-70% yeemfuno zokuhamba kompompo ingasetyenziselwa ukusebenza ngokuhambelanayo, ngaphandle kwempompo ye-spare, ekugcinweni kwempompo, enye impompo isajongene ne-70% yemveliso yezothutho.
I-4, ipompo efuna iiyure ezingama-24 zokusebenza ngokuqhubekayo, iipompo ezintathu kufuneka zisetyenziswe, umsebenzi omnye, ukulinda okukodwa, kunye nokugcinwa okunye.
Yahlula phakathi kwenyaniso nobuxoki
Okokuqala, ukupakishwa kwemveliso yempompo yokuqala okanye abavelisi abaxhasayo ngokuqhelekileyo kusemgangathweni, ukubhala ngesandla kucacile kwaye kuqhelekileyo, kwaye kukho amagama eemveliso ezicacileyo, iinkcukacha kunye neemodeli, iimpawu zokuthengisa ezibhalisiweyo, amagama efektri, iidilesi zefektri kunye neenombolo zefowuni; Ukupakishwa ngokubanzi kwezincedisi zomgunyathi kurhabaxa, kwaye idilesi yefektri kunye negama azicacanga.
Okwesibini, umphezulu wempompo yamanzi ofanelekileyo ugudileyo kwaye unomsebenzi olungileyo. Okukhona amalungu abaluleke kakhulu, kokukhona uphezulu ukuchaneka kokusetyenzwa, kokukhona ngqongqo ukupakishwa kothintelo lomhlwa kunye nothintelo lomhlwa. Xa kuthengwa, ukuba amalungu afunyaniswa enamabala omhlwa okanye iindawo zerabha eziqhekekileyo, ukulahleka kwe-elasticity okanye umphezulu wejenali unemigca yokulungisa eqaqambileyo, akufuneki ibe ngamalungu okuqala.
Okwesithathu, ukubonakala kweepompo eziphantsi ngamanye amaxesha kulungile. Nangona kunjalo, ngenxa yenkqubo yemveliso ehluphekileyo, kulula ukuba yonakaliswe, xa kuthengwa, nje ngokuba icala, ikona kunye nezinye iindawo ezifihliweyo zezixhobo, unokubona umgangatho wenkqubo yezixhobo.
Okwesine, ezinye iimpompo zihlaziywe iindawo zenkunkuma, ngoko nje i-accessory yepeyinti yomphezulu inokufumaneka emva kwepeyinti endala, impompo enjalo ingcono ukuba ungayisebenzisi.
Okwesihlanu, iinxalenye ezithengiweyo zifakwe kwimoto, kuxhomekeke ekubeni ingaba kwaye inokudibanisa okulungileyo kwezixhobo. Ngokuqhelekileyo, iindawo zokuqala zinokulinganiswa kakuhle kwimoto, kwaye iindawo ezingaphantsi zinzima ukusebenzisana omnye nomnye ngenxa yenkqubo embi kunye nephutha elikhulu lokucubungula.
Okwesithandathu, ukuze kuqinisekiswe ukuba ubudlelwane bendibano yempompo buhlangabezana neemfuno zobugcisa, ezinye iindawo eziqhelekileyo zibhalwe ngamanqaku endibano ukuqinisekisa ukufakwa okuchanekileyo kwezixhobo, ukuba akukho phawu okanye uphawu olungacacanga alukwazi ukuchongwa, akunjalo. izincedisi ezifanelekileyo.
Okwesixhenxe, indibano yempompo eqhelekileyo kunye nezixhobo kufuneka zichaneke ukuze kuqinisekiswe ukulayishwa kakuhle kunye nokusebenza okuqhelekileyo. Ezinye zeenxalenye ezincinci kwindibano zilahlekile, kulula ukuqalisa ukulayisha imoto ukuze kubangele ubunzima, iindawo ezinjalo zinokuba ziinxalenye zomgunyathi.
Okwesibhozo, ezinye izincedisi ezibalulekileyo, ngakumbi iklasi yendibano, ngokubanzi kunye nemiyalelo, izatifikethi, ukwenzela ukukhokela abasebenzisi ukufaka, ukusebenzisa kunye nokugcinwa, indibano yomgunyathi ngokubanzi ayiyi kuba nemiyalelo yofakelo eneenkcukacha zokukhokela ezi.
