Engineering Dej Pumps: Cov Khoom Siv Hluav Taws Xob rau Kev Siv Hluav Taws Xob
Raws li cov cuab yeej tseem ceeb uas hloov cov tshuab hluav taws xob rau hauv lub zog ua kua, lub tshuab dej twj tso kua mis ua haujlwm ua "lub plawv dej" ntawm kev tsim kho vaj tse thiab kev tsim khoom lag luam, ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv thaj chaw xws li lub zog, kev ua haujlwm hauv nroog, thiab kev lag luam tshuaj lom neeg. Nws lub luag haujlwm tseem ceeb yog thauj, nias, thiab xa cov kua dej los ntawm lub zog- tsav tsheb, ua kom muaj kev ua haujlwm tsis tu ncua ntawm ntau yam txheej txheem engineering.
Raws li lawv txoj haujlwm ua haujlwm, cov twj tso kua dej engineering feem ntau muab faib ua ob pawg: vane- hom thiab cov twj tso kua mis zoo. Vane- hom twj tso kua mis, sawv cev los ntawm cov twj centrifugal, tsim kom muaj zog centrifugal los ntawm qhov siab -kev sib hloov ceev ntawm lub impeller, uas cuam tshuam cov kua mus rau sab ntug ntawm lub impeller los ua kev kub siab, thaum qis - cheeb tsam siab yog tsim nyob rau hauv nruab nrab, txuas ntxiv nqus cov kua hauv. Cov twj tso kua mis hloov pauv zoo xa cov kua los ntawm kev hloov lub ntim ntawm lub chaw ua haujlwm siv cov khoom xws li pistons lossis lub zog. Piv txwv li, iav twj siv feem ntau siv rau hauv lub zog cog roj lubrication tshuab yog tsim rau kev ua haujlwm uas yuav tsum tau qis qis thiab siab siab.
Qhov tseem ceeb ntawm kev ua haujlwm tsis zoo txiav txim siab qhov xwm txheej cuam tshuam ntawm lub twj tso kua dej. Flow tus nqi qhia tus nqi ntawm cov kua xa tawm ib lub sij hawm, ntsuas hauv cubic meters ib teev; lub taub hau sawv cev rau qhov siab uas cov kua tau lifted, cuam tshuam los ntawm cov yeeb nkab tsis kam thiab kua ntom ntom; efficiency qhia txog lub zog hloov dua siab tshiab efficiency, nrog rau qhov zoo tshaj plaws efficiency point yog ib tug tseem ceeb qhia rau kev lag luam. Cov kev txwv no tau nthuav tawm los ntawm kev ua haujlwm nkhaus, xws li Q-H nkhaus, uas qhia txog kev sib raug zoo ntawm tus nqi ntws thiab lub taub hau, muab cov lus qhia tseem ceeb rau kev xaiv.
Kev lag luam txoj kev loj hlob yog qhia peb qhov tseem ceeb: Ua ntej, kev siv hluav taws xob. Tsav los ntawm cov cai tiv thaiv ib puag ncig, siab - zog ua tau zoo- txuag cov twj tso kua mis tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thiab kev tsim kho, txhawm rau txo qis kev siv hluav taws xob. Thib ob, kev txawj ntse. Los ntawm cov ntaub ntawv thev naus laus zis, tiag tiag - lub sijhawm saib xyuas ntawm kev ua haujlwm tau ua tiav, txhim kho cov cuab yeej kev ntseeg siab. Peb, tshwj xeeb. Cov twj tshwj xeeb uas txhaws- tiv taus thiab corrosion- tiv taus yog tsim los rau cov xov xwm tshwj xeeb xws li dej phwj tuaj thiab cov kua dej corrosive. Tam sim no, qhov zoo ntawm cov khoom siv hauv tsev yog nyob ze rau cov qauv thoob ntiaj teb, tab sis cov kev cov nyom tseem nyob, suav nrog kev hloov kho thev naus laus zis sai thiab xav tau siab rau kev tshawb fawb thiab kev tsim peev txheej.
Los ntawm cov dej hauv nroog mus rau kev cog hluav taws xob, los ntawm kev tiv thaiv hluav taws mus rau kev thauj tshuaj lom neeg, kev ua haujlwm thiab kev ntseeg siab ntawm engineering twj ncaj qha cuam tshuam rau qhov project zoo thiab kev ua tau zoo, thiab lawv cov kev tsim kho thev naus laus zis tau ib txwm ua nrog kev lag luam kev vam meej.
