Cov pob qij txha nthuav dav hauv cov tshuab xa hluav taws xob yuav tsum tau tu ncua.
Ua ntej tshaj plaws, kev nthuav dav sib koom ua ke yuav raug cuam tshuam los ntawm kev yaig thiab corrosion ntawm nruab nrab thiab kev hloov chaw thiab kev co ntawm lub raj xa dej thaum siv. Piv txwv li, tus taw qhia lub tog raj kheej tuaj yeem hnav vim ntev-sim xov tooj tawm tswv yim, thiab cov ntaus ntawv sib khi yuav txo qis nruj vim kev xeb.
Kev kho tsis tu ncua tuaj yeem ntes cov teeb meem muaj peev xwm hauv lub sijhawm. Lub sijhawm txij nkawm feem ntau yog raws li kev ua haujlwm ib puag ncig thiab kev ua haujlwm ntawm cov raj xa hluav taws xob. Feem ntau, hauv qhov chaw ua haujlwm hnyav (xws li cov chaw ua haujlwm corrosive, qhov kev kuaj xyuas kub thiab nqa tawm txhua 3-6 lub hlis; Yog tias qhov chaw ua haujlwm yog qhov zoo, nws tuaj yeem tshawb xyuas ib xyoos ib zaug.
The inspection content mainly includes the appearance inspection, to see whether the expansion joint has signs of leakage, whether the bellows have deformation and cracks, whether the end ring and the nozzle are firmly connected, and whether the sealing device is intact. Nyob rau tib lub sijhawm, cov kev hloov pauv ntawm kev nthuav dav sib koom tes yuav tsum tau kuaj xyuas kom meej tias nws tseem tuaj yeem ua tau raws li cov kev xav tau ntawm cov raj xa dej.
Los ntawm kev saib xyuas ib txwm, lub neej kev pabcuam ntawm kev nthuav dav muaj peev xwm txuas ntxiv, thiab ua tau kev nyab xeeb kev nyab xeeb, thiab ua tau kev nyab xeeb kev nyab xeeb thiab kev ua haujlwm kev nyab xeeb thiab kev nyab xeeb ntawm cov raj xa dej.
