split case pump meaning

1. Piping Requirements rau Pump Suction thiab Discharge Piping

1-1. Tag nrho cov kav dej txuas nrog lub twj tso kua mis (pipe burst test) yuav tsum muaj kev ywj pheej thiab ruaj khov kev txhawb nqa los txo cov raj xa dej thiab tiv thaiv qhov hnyav ntawm cov kav dej los ntawm nias ntawm lub twj tso kua mis.

1-2. Adjustable brackets yuav tsum tau muab tso rau ntawm lub inlet thiab qhov hluav taws xob pipelines ntawm lub twj tso kua mis. Rau cov kav dej uas muaj kev vibration, damping brackets yuav tsum tau muab ntsia kom kho cov kav dej kom zoo thiab txo lub zog ntxiv ntawm lub twj tso kua mis nozzle los ntawm kev teeb tsa yuam kev.

1-3. Thaum lub raj xa dej txuas lub twj tso kua mis thiab cov khoom siv luv luv thiab ob qho tib si tsis nyob rau tib lub hauv paus, cov kav dej sib txuas yuav tsum hloov tau, los yog cov hlau hose yuav tsum tau ntxiv los them rau qhov tsis sib haum xeeb ntawm lub hauv paus.

1-4. Txoj kab uas hla ntawm lub tshuab nqus tsev thiab cov kav dej tso tawm yuav tsum tsis txhob me dua li lub twj tso kua mis inlet thiab qhov hluav taws xob diameters.

1-5. Lub tshuab nqus dej ntawm lub twj tso kua mis yuav tsum ua tau raws li qhov zoo ntawm lub taub hau (NPSH) xav tau los ntawm lub twj tso kua mis, thiab cov yeeb nkab yuav tsum luv li sai tau nrog ob peb lem. Thaum lub raj xa dej ntev tshaj qhov kev ncua deb ntawm cov khoom siv thiab lub twj tso kua mis, thov nug cov txheej txheem rau kev suav.

1-6. Txhawm rau tiv thaiv cavitation ntawm ob chav nqus twj tso kua mis, qhov siab ntawm qhov inlet nozzle yeeb nkab los ntawm cov khoom siv mus rau lub twj tso kua mis yuav tsum tau maj mam txo qis, thiab yuav tsum tsis muaj U-shaped thiab hauv nruab nrab! Yog tias nws tsis tuaj yeem zam tau, lub valve yuav tsum tau muab ntxiv rau ntawm qhov chaw siab, thiab lub valve yuav tsum tau ntxiv rau ntawm qhov qis.

1-7. Qhov ntev ntawm cov yeeb nkab ncaj nraim ua ntej lub twj tso kua mis inlet ntawm lub centrifugal twj tso kua mis yuav tsum tsis txhob tsawg tshaj li 3D ntawm lub inlet txoj kab uas hla.

1-8. Rau ob-suction twj, txhawm rau kom tsis txhob muaj cavitation los ntawm kev nqus dej tsis sib xws hauv ob qho tib si cov lus qhia, cov kav dej ob lub tshuab nqus tsev yuav tsum tau npaj symmetrically kom ntseeg tau tias txawm tias ntws tawm ntawm ob sab.

1-9 Kev npaj cov kav dej ntawm lub twj tso kua mis kawg thiab tsav tsheb kawg ntawm lub twj tso kua mis reciprocating yuav tsum tsis txhob cuam tshuam lub disassembly thiab kev saib xyuas ntawm lub piston thiab khi pas nrig.

2. Lub Chaw Pabcuam Pipeline ntawm lubSplit Case Pump

2-1. Lub raj xa dej sov: Thaum qhov kub ntawm cov khoom xa los ntawm lub twj tso kua mis centrifugal siab tshaj 200 ° C, lub twj tso kua mis sov yuav tsum tau nruab kom muaj cov khoom siv me me ntawm cov kav dej tawm ntawm lub twj tso kua mis khiav mus rau qhov hluav taws xob ntawm qhov hluav taws xob. lub twj tso kua mis standby, ces ntws los ntawm lub twj tso kua mis standby, thiab rov qab mus rau lub twj tso kua mis inlet kom lub twj tso kua mis standby Lub twj tso kua mis yog kub standby kom yooj yim pib.

2-2. Anti-condensation kav: DN20 25 anti-freeze kav yuav tsum tau ntsia rau cov twj tso kua mis nrog condensable nruab nrab ntawm qhov kub thiab txias, thiab txoj kev teeb tsa yog tib yam li cov kav dej sov.

2-3. Cov yeeb nkab sib npaug: Thaum qhov nruab nrab yog qhov ua rau gasification ntawm lub twj tso kua mis inlet, qhov sib npaug ntawm cov yeeb nkab uas tuaj yeem rov qab mus rau qhov chaw roj av ntawm cov khoom siv sab saud tuaj yeem ntsia nruab nrab ntawm lub twj tso kua mis inlet nozzle thiab lub twj tso kua mis inlet kaw. , kom cov roj generated tuaj yeem ntws rov qab. Txhawm rau kom tsis txhob muaj cov twj tso kua mis cavitation, ib qho kev txiav tawm yuav tsum tau nruab rau ntawm cov yeeb nkab sib npaug.

2-4. Yam tsawg kawg nkaus rov qab yeeb nkab: Txhawm rau tiv thaiv lub twj tso kua mis centrifugal los ntawm kev khiav hauj lwm hauv qab qhov tsawg kawg nkaus ntawm lub twj tso kua mis, qhov tsawg kawg nkaus rov qab yeeb nkab ntawm lub twj tso kua mis yuav tsum tau teem kom rov qab ib feem ntawm cov kua los ntawm lub twj tso kua mis tawm qhov chaw nres nkoj mus rau lub thawv ntawm qhov sib cais. case twj tso kua mis suction chaw nres nkoj los xyuas kom meej qhov txaus tus nqi ntawm lub twj tso kua mis.

Vim qhov tshwj xeeb ntawm lub twj tso kua mis, nws yuav tsum muaj kev nkag siab tag nrho ntawm kev ua tau zoo ntawm lub twj tso kua mis thiab cov txheej txheem cov ntaub ntawv uas khiav hauv lub twj tso kua mis, thiab kev teeb tsa tsim nyog ntawm nws cov kav dej nkag thiab qhov hluav taws xob yuav tsum tau ua kom ntseeg tau tias nws muaj kev nyab xeeb thiab ruaj khov. .
