Cov twj sib nqus ua ke yog cov khoom siv sib nqus hauv cov tshuaj lom neeg, tshuaj, thiab kev lag luam tiv thaiv ib puag ncig. Cov khoom xaiv ncaj qha cuam tshuam lawv corrosion tawm tsam, kev pabcuam lub neej, thiab kev nyab xeeb. Nkag siab cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm cov twj sib nqus yog qhov tseem ceeb rau kev lag luam lag luam txawv teb chaws.
Cov khoom siv tseem ceeb ntawm cov twj sib xyaw suav nrog lub tes tsho sib cais, cuam tshuam, cov twj tso kua mis, thiab bearings. Cov ntaub ntawv ntawm cov feem no yuav tsum yog customized raws li cov yam ntxwv ntawm lub mumped nruab nrab. Kev rho tawm cov tes tes tsho yog feem ntau ua cov tshuaj fluoroplastics (xws li PFA thiab PTFE), xws li cov hlau (xws li 304 thiab 316L), lossis hastelloy. Fluoropoplastics muaj cov tshuaj tsis zoo thiab haum rau cov chaw hnyav xws li muaj zog acids thiab alkalis. Txawm li cas los xij txawm li cas los xij, yog dav siv nyob rau hauv cov ntaub ntawv muaj kev lag luam dav dav vim nws cov kev siv hluav taws xob zoo heev. Siab -}}}} Cov ntaub ntawv kawg li Hastelloy yog siv nyob rau hauv ntau ib puag ncig ib puag ncig kom ntseeg tau tias ntev} lub sij hawm, cov haujlwm ruaj khov.
Cov ntaub ntawv ntawm kev cuam tshuam thiab cov ncej nqus dej kuj tseem ceeb heev. Cov ntaub ntawv tsis sib xws cov ntaub ntawv suav nrog kev ua kom haum (xws li PP thiab PVDF) thiab stainless hlau. Lub teeb yuag yas yas ua kom txo cov zog siv hluav taws xob, thaum stainless hlau impellers yog tsim nyog rau cov siab siab thiab cov neeg khiav dej siab. TWJ Shafts Shafts yog ib txwm ua los ntawm cov hlau uas tsis muaj hlau lossis tej hub. Tej hub shafts, vim lawv lub siab tawv thiab hnav tsis kam, ua tshwj xeeb hauv kev tawm tswv yim zoo.
Tsis tas li ntawd, cov khoom siv rau cov twj sib nqus yuav tsum tau xaiv raws li kev ua haujlwm. Silicon carbide (sic) thiab sau polytetrosraethylene (PTFE) yog cov khoom siv. Cov qub yog tsim nyog rau kev kub ceev thiab siab loads, thaum lub tom kawg expels ntawm tus kheej- lubrication tsis kam.
Rau cov tuam txhab ua lag luam tawm txawv teb chaws, muaj tseeb kev nkag siab txog cov khoom siv ntawm cov twj nqus hlau pab muab cov kev daws teeb meem uas tau sib raws li cov teb chaws sib txawv thiab cov cheeb tsam. Piv txwv li, EU kev ua lag luam muaj cov ntaub ntawv nruj ib puag ncig, thaum Middle East tsom ntau rau high- kub thiab roj tsis kam. Los ntawm kev xaiv cov khoom siv tsim nyog, cov tuam txhab tuaj yeem tsis tsuas yog txhim kho cov khoom lag luam kev sib tw, yog li tau txais qhov chaw muaj zog hauv kev ua lag luam thoob ntiaj teb.
