Multi-stage Barrel Casing Pump (API610 BB5)

1. Cylinder: Maererano neflange pressure level, silinda ine zvimiro zviviri: kukanda kana kuumba; iyo centreline tsigiro yehumburumbira inogona kuvandudza kugadzikana kwemafuta uye kutsungirira yakakwira nozzle mutoro.

2. Core package: The core package (guide vane, impeller assembly, shaft, pump cover, bearing box, etc.) inotora dhizaini inobvisa, iyo inogonesa kuongorora nekugadzirisa pombi pasina kufambisa pombi yekupinza uye yekubuda.

3. Impeller uye gwara vane: The impeller uye gwara vane dzakanyatsokandwa. Iyo yakajairwa impeller uye shaft inotsvedza-yakaiswa uye yakagadziriswa nhanho nhanho muhafu-mhete. Kune inorema basa rekushanda mamiriro, iyo impeller inopindirana inokodzera, uye nhanho inoshandiswa pane imwe neimwe nhanho yeimpeller. Iyo shaft chimiro inofambisa kuiswa uye kugadzirisa; DN80 (outlet) uye pamusoro pezvinyorwa zvinogona kuve nekutanga-nhanho kaviri-kusveta impeller yekuvandudza cavitation kuramba NPSH.

4. Axial simba rekuenzanisa: Mapombi akarongwa munhevedzano uye anoshandisa chigubhu chekuenzanisa kuti aenzanise simba reaxial, uye simba rinosara reaxial rinotakurwa nekusimudzira; ma impellers akarongwa kudzokera kumashure symmetrically kuti azvienzanise simba reaxial, uye nechepakati bushing uye huro bushing kuenzanisa residual shaft force, the thrust inotakura chete mitoro yakaderera.

5. Bearings uye lubrication: Mabheji anoshandisa mafuta mhete self-lubricating chimiro mabheji kana kumanikidzirwa lubrication chimiro mabheji maererano neshaft simba uye nekukurumidza. Iyo yese nhevedzano inotora kutakura isolator mhando zvisimbiso, uye kabhoni simbi inotakura bhokisi inotsigirwa pa360 °. Bhokisi rinotakura rinogona kufefetwa Kutonhodza kana kutonhora kwemvura kunowanikwa.

6. Shaft chisimbiso: Iyo yekuisa chisimbiso inoshandisa 4th edition yeAPI682 "Centrifugal Pump uye Rotary Pump Seal System" uye inogona kugadzirwa nemhando dzakasiyana dzekuisa chisimbiso, kutsvaira, uye kutonhora mhinduro.
