1. Pasi pemamiriro emvura yakachena (ine zvimedu zvakasimba zvisingasviki 0.1%), kushanda zvakanaka hakuzodonhedzi kupfuura 6% mushure mokushanda kwe5000h pasina kuvandudzwa;
2. Pasi pemamiriro emvura yetsvina ine zvimedu zvakasimba pasi pe 0.1% kusvika ku1%, inomhanya kwe3000h pasina kushandura, kudonha kwehutano hakupfuuri 5%;
3. Pasi pemamiriro emvura yetsvina ine zvimedu zvakasimba zve 1-.5%, kubudirira hakuzodonhedzi kupfuura 6% kana ichimhanya kwe2000h pasina kugadzirisa kukuru.
Zvimiro zvemhando yeMD inopfeka-inodzivirira yakawanda-nhanho centrifugal pombi yemugodhi:

Chikamu che stator chinonyanya kuumbwa nechikamu chepamberi, chikamu chepakati, chigadziro chevane, chikamu chemashure, chigadziko chekutakura uye chivharo chekamuri yekuenzanisa.Zvikamu zvakabatanidzwa netsvimbo uye nati.Chikamu chemberi uye chikamu chemashure chinogadziriswa pachigaro chepombi nemabhoti uye nuts.
Rotor zvikamu zvinonyanya kugadzirwa ne impeller, impeller block, balance block, balance disc uye shaft sleeve zvikamu zvakasimbiswa nediki denderedzwa nzungu, uye inomisikidzwa pane shaft ine flat kiyi kudzivirira kutenderera.Iyo yose rotor inotsigirwa pamabhengi kumativi ose maviri.Iyo rotor yakabatana zvakananga kune mota ine elastic pini yekubatanidza.
Kuti utsivise kuwedzera, pedhi yemazino inoiswa pakati pechikamu chekupedzisira uye sleeve sleeve, iyo inofanira kuchinjwa kana pombi inogadziriswa.
Iyo yakawanda-nhanho centrifugal pombi yekupfeka-inodzivirira migodhi inotora chiyero cheplate hydraulic balance mudziyo unogona kudzikamisa uye otomatiki simba reaxial.Chishandiso ichi chine zvikamu zvina: balance plate, balance plate, balance sleeve uye balance block.
Iyo rotor chikamu cheMD mhando yekuchera multistage centrifugal pombi inonyanya kuumbwa neshaft uye impeller, shaft sleeve, balance disc uye zvimwe zvikamu zvakaiswa pashaft.Nhamba yezviputi zvinoenderana nehuwandu hwematanho epombi.Zvikamu zviri mugomba zvakasungirirwa nekiyi flat uye shaft nut kuti zvibatanidzwe ne shaft.Iyo yose rotor inotsigirwa nekukunguruka mabheji kana kutsvedza mabhengi kumativi ese ari maviri.Mabheji anotemerwa maererano nemhando dzakasiyana, uye hapana kana imwe yadzo inotakura axial simba.Iyo axial simba inofananidzwa nedhisiki disc.Munguva yekushanda kwepombi, rotor inobvumirwa kushambira axially mupombi casing, uye radial ball bearings haigoni kushandiswa.Iyo inoputika inotakura mafuta, iyo inotsvedza inotsvedza nemafuta akaonda, uye mhete yemafuta inoshandiswa pakuzvinatsa, uye mvura inotenderera inoshandiswa kutonhora.Nzvimbo dzekuisa chisimbiso pakati pechikamu chemukati chemvura, chikamu chepakati uye chikamu chekubuda kwemvura chepombi zvese zvakanamwa nemolybdenum disulfide girisi, uye mhete yekuisa chisimbiso uye inotungamira vane sleeve inoiswa pakati peiyo rotor chikamu uye yakagadziriswa chikamu chekuisa chisimbiso.Kana dhigirii rekupfeka uye kubvarura rakakanganisa kushanda kwepombi, inofanira kutsiviwa.
Mafomu ekuvharisa emigodhi multistage centrifugal pombi anosanganisira mechanical seals uye kurongedza zvisimbiso.Apo pombi yakavharwa nekutakura, nzvimbo yemhete yekutakura inofanira kuva yakarurama, kusungirirwa kwekutakura kunofanira kunge kwakakodzera, uye zvinokurudzirwa kuti mvura inogona kudonha kudonha.Zvinhu zvakasiyana-siyana zvekuisa chisimbiso zvepombi zvakaiswa mugomba rekuvhara, uye gomba rinofanira kuzadzwa nemvura yeimwe dzvinyiriro, uye kuvhara kwemvura, kutonhora kwemvura kana kugadzika kwemvura kunosarudzika.Bushing inotsiva inoiswa pachisimbiso che shaft kuchengetedza pombi shaft.
Matenderedzwa erudzi urwu rwemigodhi yakawanda-nhanho ye centrifugal pombi inoenderana newachi kana ichitariswa kubva kudivi remota yekutanga.
Mirayiridzo yekutanga pombi:

Usati watanga migodhi yakawanda-nhanho centrifugal pombi, pombi rotor inofanira kutenderera kuti ione kana rotor inoshanduka;
Tarisa uone kana kutungamira kwemota kunoenderana negwara repombi;
Vhura vharafu yekukwevera pombi, vhara gedhi repombi yepombi yekubuda kwepombi uye gauge yekumanikidza jongwe, kuitira kuti pombi izadzwe nemvura, kana kushandisa vacuum system kubvisa mhepo mupombi yekudhonza uye pombi;
Tarisa kusimba kwemabhoti ekubatanidza pombi uye motokari uye kuchengetedzwa kwakapoteredza pombi, kuitira kuti pombi yakagadzirira kutanga;
Tanga injini.Mushure mekunge pombi ichimhanya zvakajairika, vhura iyo yekumanikidza geji jongwe uye zvishoma nezvishoma vhura iyo pombi yekubuda gedhi vharafu kusvika iyo yekumanikidza geji inonongedza kune inodiwa kudzvanywa (dzora iyo pombi yakapihwa kusimudzwa zvinoenderana nekubuda kwegeji yekumanikidza kuverenga).

Operation
Iyo yekupfeka-inodzivirira yakawanda-nhanho yecentrifugal pombi yemugodhi inoshandisa chiyero chepombi kuenzanisa simba reaxial.Mvura yakadzikama inoyerera ichibuda kubva pachiyero chemudziyo.Chiyereso chemvura chinosanganiswa nechikamu chekupinda kwemvura kubva pachiyero chemvura pombi, kana pombi pfupi inogadzirwa mukamuri yekuenzanisa.Iyo chubhu inoyerera ichibva papombi.Kuti uve nechokwadi chekushanda kwakajairika kwepombi, pombi yemvura yakaenzana haifaniri kuvharwa;
Mukati mekutanga uye kumhanya, iwe unofanirwa kutarisisa kuti ucherechedze kuverenga kwemamita, kungave kudziya kwekutakura, kutakura kuvuza uye kupisa, uye kuzununguka uye ruzha rwepombi zvakajairika.Kana chero mamiriro ezvinhu asina kunaka akawanikwa, anofanira kugadziriswa nenguva;
Shanduko yekutakura tembiricha inokwira inoratidza gungano remhando yepombi, iyo inotakura tembiricha inokwira haifanire kunge yakakwira pane ambient tembiricha 35 ℃, uye tembiricha yepamusoro haifaniri kunge yakakwira kupfuura 75 ℃;
Pane imwe axial movement yepombi rotor panguva yekushanda, uye kufamba kweaxial kunofanira kunge kuri mukati mehutano hunobvumirwa, uye kukosha kwekuregererwa pakati pemagumo ezviso zvemotokari uye kubatanidzwa kwepombi yemvura kunofanira kuvimbiswa;
Munguva yekushanda kwepombi, kupfeka kweimpeller, kuvhara mhete, gwara vane sleeve, shaft sleeve, balance disc uye zvimwe zvikamu zvinofanira kuongororwa nguva dzose.Kana kupfeka kwakanyanya, kunofanira kuchinjwa nenguva.

Mira
Usati wavhara, jongwe regeji rekumanikidza rinofanira kuvharwa, uye gedhi rekubuda kunze rinofanira kuvharwa zvishoma nezvishoma.Mushure mekunge valve yekubuda yakavharwa, motokari inofanira kuvharwa.Mushure mokunge pombi yamira zvakasimba, valve yekusveta yepombi inofanira kuvharwa;mvura iri mupombi inofanira kusunungurwa.Yakacheneswa uye nemafuta, yakarongedzwa kuti ichengetedze.
