Kev xaiv cov twj tso kua dej kub yuav tsum tau ua raws li cov txheej txheem ntws, dej thiab cov dej yuav tsum tau ua, thiab txiav txim siab los ntawm tsib yam: lub peev xwm thauj cov kua, lub taub hau khoom, cov khoom ua kua, cov kav dej tso, thiab kev ua haujlwm.
1. Tus nqi ntws yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev xaiv lub twj tso kua dej kub, uas cuam tshuam ncaj qha rau kev tsim khoom thiab kev thauj mus los ntawm tag nrho cov khoom siv. Yog tias lub koom haum tsim qauv tuaj yeem suav qhov ib txwm, yam tsawg kawg nkaus, thiab qis qis qis ntawm cov twj tso kua mis hauv cov txheej txheem tsim. Thaum xaiv lub twj tso kua mis, qhov siab tshaj plaws ntws tus nqi yuav tsum tau muab coj los ua lub hauv paus, thaum txiav txim siab qhov dej ntws li qub. Thaum tsis muaj qhov txwv qis qis, nws feem ntau pom zoo kom siv 1.1 npaug ntawm tus nqi ntws ib txwm ua raws li qhov txwv qis qis.
2. Lub taub hau xav tau rau cov cuab yeej siv tshuab yog lwm cov ntaub ntawv tseem ceeb rau kev xaiv cov twj tso kua mis, thiab feem ntau lub taub hau yuav tsum tau xaiv los ntawm qhov loj ntawm cov npoo los ntawm 5% -10%.
3. Cov khoom ntawm cov kua muaj xws li lub npe ntawm cov kua nruab nrab, lub cev muaj zog, cov khoom siv tshuaj, thiab lwm yam khoom. Lub cev lub cev muaj xws li kub, ntom, viscosity, txoj kab uas hla ntawm cov khoom hauv nruab nrab, thiab cov ntsiab lus roj. Qhov no suav nrog lub taub hau ntawm lub kaw lus, qhov tseem ceeb cavitation pub suav, thiab hom twj tso kua mis haum. Cov khoom siv tshuaj lom neeg feem ntau yog xa mus rau cov tshuaj corrosiveness thiab toxicity ntawm cov kua nruab nrab, uas yog cov txheej txheem tseem ceeb rau kev xaiv cov khoom siv twj tso kua mis thiab xaiv hom kev foob.
4. Cov txheej txheem kev teeb tsa ntawm lub raj xa dej ntawm cov khoom siv xa mus rau qhov siab, ntu ntu, thiab kev taw qhia ntawm cov kua xa tawm, nrog rau cov ntaub ntawv xws li qib qis tshaj plaws ntawm cov dej nqus dej thiab cov kua dej siab tshaj plaws ntawm cov pa tawm sab nraud, nrog rau pipeline specifications thiab lawv qhov ntev, cov ntaub ntawv, yeeb nkab specifications, kom muaj nuj nqis, thiab lwm yam., nyob rau hauv thiaj li yuav xam lub comb taub hau thiab xyuas cov cavitation pub.
5. Muaj ntau yam kev khiav hauj lwm, xws li kev khiav hauj lwm ntawm cov kua T, tag nrho vapor force P, suction sab siab PS (zoo), tso tawm sab thawv siab PZ, qhov siab, ib puag ncig kub, txawm tias kev ua haujlwm tsis sib xws lossis tsis tu ncua, thiab seb lub twj tso kua mis taw qhia yog tsau lossis txav tau.
Kev ceeb toom los ntawm cov chaw tsim khoom ntawm lub twj tso kua dej kub: Raws li cov txheej txheem xaiv saum toj no, peb tuaj yeem yooj yim xaiv lub twj tso kua dej kub tsim nyog raws li peb tus kheej xav tau. Tom qab nruj me ntsis raws li cov kev xaiv rau cov twj tso kua dej, peb yuav tsum tau xyuam xim rau qhov tseeb hais tias cov dej twj tso kua mis xaiv yuav tsum muaj me me, tsis tshua muaj nqi, zoo heev cov yam ntxwv, ntev kev pab cuam lub neej, ruaj khov, thiab tsis tshua muaj nqi khiav lag luam.
