Lub twj tso kua mis dej yog ib qho khoom siv uas hloov lub zog txhua yam - lossis lwm yam kev siv lub zog - mus rau hauv kinetic thiab siab zog ntawm cov kua; nws yog dav siv nyob rau hauv teb xws li kev ua liaj ua teb irrigation, landscaping, industrial water supply, drainage, thiab cog cov cuab yeej tiv thaiv. Txawm hais tias muaj ntau hom twj tso kua dej, lawv cov khoom tseem ceeb feem ntau suav nrog lub twj tso kua mis, lub impeller, twj tso kua mis, bearings, sealing mechanism, thiab inlet thiab outlet ports. Cov qauv tsim tshwj xeeb sib txawv los ntawm hom; Piv txwv li, cov twj centrifugal feem ntau cia siab rau qhov siab - kev sib hloov ceev ntawm lub impeller los thauj cov kua, hos cov twj tso kua mis thiab cov twj diaphragm ua tiav cov kua hloov los ntawm cov lus tsa suab.
Lub twj tso kua mis ua haujlwm ua lub tsev tseem ceeb, kaw thiab tiv thaiv cov khoom siv sab hauv thaum tsim txoj kev ntws rau cov kua. Nws yog nruab nrog inlet thiab qhov hluav taws xob ports; Cov kua nkag mus rau hauv lub twj tso kua mis chamber los ntawm lub inlet, nce lub zog los ntawm lub internal mechanical Cheebtsam, thiab tom qab ntawd tawm los ntawm lub qhov hluav taws xob. Lub casing yuav tsum muaj lub zog txaus thiab tiv thaiv corrosion- yuav tsum tau ua kom nruj dua thaum tuav cov kua uas muaj impurities lossis corrosive. Lub impeller yog lub luag haujlwm tseem ceeb hauv cov twj centrifugal; los ntawm rotating, nws generates centrifugal quab yuam uas imparts tshaj tawm thiab siab rau cov kua, li no enabling nruam ntws.
Lub twj tso kua mis ncej yog lub luag haujlwm rau kev xa cov tshuab hluav taws xob los ntawm lub zog hluav taws xob mus rau lub impeller, tsav nws tig mus rau ntawm qhov kev taw qhia thiab ceev. Txhawm rau kom muaj kev ruaj ntseg thiab tiv thaiv kev khoov lossis tawg thaum lub sijhawm ua haujlwm ntev -, cov ncej yuav tsum muaj lub zog siab, rigidity, thiab corrosion kuj. Bearings txhawb nqa ncej, txo kev sib txhuam thaum sib hloov thiab ua kom ruaj khov ua haujlwm. Lub lubrication tsis txaus lossis cov kabmob hnav tuaj yeem ua rau lub suab nrov thiab kev co thaum lub sijhawm ua haujlwm, yuav tsum tau kuaj xyuas thiab tu.
Lub sealing mechanism yog lwm qhov tseem ceeb, ua haujlwm los tiv thaiv cov kua xau los ntawm qhov sib txawv ntawm cov ncej thiab lub casing thaum tseem ua kom cua tawm ntawm lub twj tso kua mis chamber. Cov txheej txheem sealing feem ntau suav nrog cov tshuab sealing thiab gland packing. Raws li cov ntsaws ruaj ruaj yog nquag hnav, yuav tsum tau kuaj xyuas raws sijhawm thiab hloov pauv yog tias muaj qhov cuam tshuam loj heev tom qab siv ntev. Tsis tas li ntawd, cov twj tso kua dej tuaj yeem nruab nrog cov khoom sib txuas xws li couplings, baseplates, filtration devices, li qub, thiab cov ntsuas siab; cov no pab txhawb kev sib txuas rau lub zog siv hluav taws xob thiab txhim kho kev noj haus, tso tawm, thiab tswj kev ua haujlwm.
Cov khoom tseem ceeb ntawm lub twj tso kua dej ua haujlwm hauv kev hais kwv txhiaj kom thauj cov kua. Lub tshuab hluav taws xob muab cov khoom siv hluav taws xob, lub twj tso kua mis xa tawm lub zog no, lub impeller (lossis lwm yam kev ua haujlwm) ua haujlwm ntawm cov kua dej, thiab cov twj tso kua mis ua rau cov dej ntws, thaum bearings thiab sealing tshuab ua haujlwm ruaj khov thiab txhim khu kev qha. Raws li cov qauv tsim thiab cov ntaub ntawv sib txawv nyob ntawm daim ntawv thov, xaiv thiab tswj lub twj tso kua mis yuav tsum muaj kev ntsuam xyuas ntau yam xws li tus nqi ntws, lub taub hau, kua dej, ib puag ncig kev ua haujlwm, thiab lub zog yuav tsum tau ua kom muaj txiaj ntsig zoo thiab kev pabcuam lub neej.
