Kev ua haujlwm zoo ntawm cov hluav taws kub hnyiab yog qhov tseem ceeb, cuam tshuam ncaj qha rau kev tiv thaiv kev nyab xeeb thaum hluav taws kub. Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm yog raws li hauv qab no:
Hluav Taws Damper Kev Ua Haujlwm
Nquag Qhib Hom: Tseem qhib raws li ib txwm muaj. Yuav kaw thaum kub nce mus txog 70℃thaum hluav taws kub, thaiv cov pa taws tawm ntawm txoj kev. Kev tuav kaw yuav tsum tau clockwise tig ntawm tus kov; rov pib dua yuav tsum ua haujlwm counterclockwise.
Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob: Nquag kaw; yuav tsum tau ua kom tej thaj chaw deb (counterclockwise tig) los ntawm lub chaw tswj hluav taws thaum muaj hluav taws. Tsis siv neeg yaj thiab kaw thaum kub txog 280 degree. Kev qhib phau ntawv yuav tsum muaj kev sib hloov counterclockwise; kaw yuav tsum tau clockwise tig.
Cov cai dav dav rau hluav taws kub li qub
Kev taw qhia kev sib hloov: Feem ntau cov hluav taws kub li qub ua raws li "clockwise kom kaw, counterclockwise kom qhib", raws li cov qauv kev sib txuas threaded.
Kev Ua Haujlwm Thaum Muaj Xwm Ceev: Cov hluav taws kub hydrant li qub qhib counterclockwise thiab kaw clockwise. Xyuas kom cov hose txuas kom zoo tswj cov dej siab. cov
Cov kev ceev faj
Seal Integrity Testing: Ib ntus kuaj lub valve ntsaws ruaj ruaj kom tiv thaiv kev puas tsuaj los ntawm kev kaw ntev. cov
Interlock Control: Hluav taws kub dampers yuav tsum ua kom kiv cua kaw thaum kaw. Cov pa hluav taws xob tso pa tawm yuav tsum ua kom tib lub sijhawm ntawm cov pa pa tawm thaum qhib. cov
