Feem ntau tsis ua haujlwm ntawm lub siab tswj hluav taws xob hydrant tsaws li qub feem ntau suav nrog cov hauv qab no:
1. Ua tsis tiav ntawm kev tswj siab
Tej zaum nws yuav yog tias cov cuab yeej tswj lub siab sab hauv puas, xws li lub caij nplooj ntoos hlav laus los yog deformation, thiab nws tsis tuaj yeem muab kev tswj xyuas lub siab.
Piv txwv li, hauv kev siv tiag tiag, nws yuav tshwm sim txawm tias nws hloov kho li cas, lub qhov hluav taws xob qhov hluav taws xob yog ib txwm siab dhau lossis qis dhau.
2. Cov teeb meem tawg
Lub valve qia tsis kaw nruj nreem, ua rau dej los ntawm lub valve qia.
Muaj cov kab nrib pleb lossis cov xuab zeb hauv lub valve lub cev nws tus kheej, ua rau cov dej ntws tawm.
Piv txwv li, dej tuaj yeem pom meej pom pom nyob ib ncig ntawm lub qhov hluav taws kub, thiab txawm tias cov dej tsuj.
3. Valve core daig
Cov impurities nyob rau hauv cov dej nkag mus rau lub valve, ua rau lub valve core txav obstructed.
Qhov hnav lossis corrosion ntawm lub valve tseem ceeb tiv thaiv nws los ntawm kev txav mus los.
Qhov no yuav tshwm sim raws li qhov tsis muaj peev xwm qhib lossis kaw lub valve ib txwm, cuam tshuam rau kev siv hluav taws xob hluav taws xob.
4. Kev ua haujlwm tsis yooj yim
Vim tsis siv sijhawm ntev lossis tsis muaj kev saib xyuas, cov khoom sib hloov yog xeb lossis daig los ntawm cov khoom txawv teb chaws.
Piv txwv li, thaum lub qhov hluav taws kub hydrant yuav tsum tau qhib thaum muaj xwm ceev, lub valve yog nyuaj tig.
5. Kev puas tsuaj
Vim muaj kev cuam tshuam sab nraud lossis ib puag ncig hnyav, qhov tshwm sim ntawm qhov hluav taws kub hydrant tsaws valve yuav raug deformed lossis puas.
Cov kev ua txhaum no tuaj yeem cuam tshuam rau kev siv ib txwm siv lub siab tswj hluav taws xob hydrant tsaws valve, yog li cuam tshuam rau kev ua haujlwm tua hluav taws. Yog li ntawd, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tsim nyog heev.
