Kev ua haujlwm nrov nrov
Lub twj tso kua mis tshiab, kiv cua, lossis cov kua dej ntws vibrations thiab suab qhia tias muaj kev degradation. Nce decibels kuj npog lwm yam kev txhawj xeeb uas xav tau kev tshuaj xyuas.
Tiv thaiv cov teeb meem yav tom ntej
Kev tiv thaiv kev tiv thaiv kev kub ntxhov hauv Is Nrias teb tuaj yeem txheeb xyuas cov kev txhawj xeeb me me ua ntej lawv dhau los ua teeb meem loj, tiv thaiv ntau yam teeb meem. Kev ntsuam xyuas lub twj tso kua mis, kev tu lub raj, thiab kev tshuaj ntsuam xyuas hluav taws xob tuaj yeem tshawb pom cov teeb meem thiab txuas ntxiv lub neej ntawm cov khoom siv. Kev cia siab rau kev kho cov tshuaj tiv thaiv tsuas yog caw cov kev pheej hmoo tsis tsim nyog thiab lub sijhawm poob. Nyob proactive them tawm mus ntev.
Kev ua raws li niaj hnub kev tiv thaiv kev saib xyuas thiab teb tam sim rau cov cim ceeb toom yog qhov tseem ceeb rau kev tiv thaiv qhov tsis tau pom dua ntawm cov khoom siv hluav taws xob thiab kev cuam tshuam. Kev tshawb pom ntxov ntawm cov teeb meem tso cai rau tus nqi- kev kho kom zoo dua qub uas tsis yog kev kho dua tshiab.
Nyeem Ntxiv:Dab tsi yog Txoj Cai Ua Haujlwm Ntawm Cov Kub Kub Exchanger?
Sab saum toj tsib Cheebtsam xav tau kev tswj xyuas zoo
Kev tshuaj xyuas zoo ib yam thiab kev pabcuam ntawm qee qhov tseem ceeb ntawm cov khoom siv hluav taws xob hloov pauv tuaj yeem txhim kho kev ua haujlwm tau zoo thiab tiv thaiv kev kho mob kub ntxhov. Nov yog tsib lub hauv paus tseem ceeb uas yuav tsum muaj kev saib xyuas yog raws li hauv qab no:
Plhaub thiab Tube
Lub plhaub thiab lub raj yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob hloov pauv rau cov cua sov. Tom qab ntau xyoo ntawm kev ua haujlwm cyclical, nplai, corrosion, thiab sediment buildup tuaj yeem kis tau rau hauv lub raj ntim.
