Kev saib xyuas tsis tu ncua yog tib txoj hauv kev los xyuas kom meej tias lub siab siab - tseem muaj kev nyab xeeb rau cov neeg ua haujlwm nyob ib puag ncig nws. Txhawm rau tshuaj xyuas lub koob valve, thawj kauj ruam yog ib txwm ua kom lub cev muaj zog thiab xyuas kom meej tias nws raug kaw. Thaum muaj kev nyab xeeb, tus kws kho mob yuav tsum saib xyuas cov cim qhia ntawm "quaj" nyob ib puag ncig ntawm lub pob ntim lossis lub kaus mom sib koom ua ke. Yog tias muaj dej noo los yog ntsev crust, nws qhia tau hais tias cov ntsaws ruaj ruaj tau pib ua tsis tiav. Tig tus kov rau nws cov lus tsa suab tag nrho tuaj yeem qhia tau yog tias cov xov sab hauv tau hnav lossis yog tias muaj kev tsim- nce ntawm qhov ntsuas hauv lub cev valve. Txhua qhov grittiness lossis kev tiv thaiv ntau dhau feem ntau txhais tau hais tias lub valve yuav tsum tau ntxuav lossis hloov.
Yog tias rab koob valve tau qhia pom tias muaj cov pa tawm los ntawm lub rooj zaum, qhov teeb meem feem ntau yog lub koob lub taub puas. Qhov no tuaj yeem tshwm sim yog tias lub valve rov qab nruj dua lossis yog tias cov khoom abrasive hauv cov kua tau eroded cov hlau. Ntau qhov chaw ua lag luam tam sim no siv cov cuab yeej acoustic leak detection los nrhiav "sab hauv leaks" uas tsis pom los ntawm sab nraud. Cov ntawv tshaj tawm kev sib tham hauv kev lag luam qhia tias kev hloov cov khoom ntim txhua ob mus rau peb xyoos yog qhov kev tiv thaiv zoo rau cov li qub hauv kev pabcuam tseem ceeb. Nrog rau qhov nce ntawm lub tswv yim ntxaib digital hauv cov chaw tsim khoom niaj hnub no, qee qhov tshiab li qub txawm suav nrog ua -hauv cov sensors uas saib xyuas lub siab thiab qhov kub thiab txias hauv lub sijhawm tiag tiag -. Qhov no tso cai rau pab pawg saib xyuas txav los ntawm lub sijhawm -raws li qhov system mus rau ib qho xwm txheej-raws li ib qho, tsuas yog kho cov khoom thaum cov ntaub ntawv qhia tias tsim nyog.
