Vim yog lub luag haujlwm tseem ceeb ntawm hluav taws kub taub hau hauv cov khoom siv hluav taws xob hauv cov khoom siv tag nrho, nws yog qhov tseem ceeb kom ua tib zoo saib xyuas nws txoj kev txij nkawm thiab kev tu cev. Thaum hluav taws kub lossis lwm yam xwm txheej ceev tshwm sim, hluav taws kub taub dej ua tus yuam sij los daws cov teeb meem. Yog li ntawd, tej teeb meem yuav tshwm sim yuav tsum muaj kev daws teeb meem sai sai, tswj cov teeb meem uas muaj hluav taws kub taub hau nws tus kheej, tswj cov txheej txheem, lossis kev tswj hwm, tsis quav ntsej.
Txawm li cas los xij, ntawm cov teeb meem no, qhov cuam tshuam ntawm hluav taws kub taub hau nws tus kheej yuav yog qhov tseem ceeb, thiab nws tseem yog qhov yooj yim tshaj plaws hauv lub neej txhua hnub. Cov kev cai kom tua hluav taws kub hydrant muaj raws li nram no:
1, nws yog qhov yuav tsum tau hais tias lub zog ntawm nws sab hauv cov feem yuav tsum tau txaus. Nyob rau hauv ib txwm muaj xwm txheej, cov li qub nyob rau hauv inlet thiab qhov hluav taws xob ntawm hluav taws hydrant twj tso kua mis yeej ib txwm qhib lub xeev. Qhov no yog vim hais tias cov hluav taws kub taub hau tsis siv, thiab nws li qub yuav xeb thiab tuag, ua rau nws tsis yooj yim thaum muaj xwm ceev. Txawm li cas los xij, feem ntau tawm hauv lub valve qhib tau tuaj yeem nkag ntau rau ntau yam rau cov zog tseem ceeb, yog li nws yog qhov tsim nyog los txhim kho lub zog ntawm nws sab hauv.
2, tus qauv ntawm hluav taws kub taub hau yuav tsum muaj nws lub neej. Vim tias cov tub sab thrust no thaum lub sijhawm ntws tawm los kuj tseem ceeb heev, tsis muaj qhov sib npaug tsim nyog yuav ua rau muaj kev puas tsuaj rau koj tus kheej.
3, cov khoom siv tsav yuav tsum ntseeg tau. Vim yog cov dav dav ntawm kev ua haujlwm, hluav taws kub hydrant qee zaum muaj cov haujlwm tsis zoo, yog li cov khoom tsav yuav tsum muaj peev xwm ua haujlwm ua ke. Tsuas yog nrog cov ntsiab lus saum toj no tuaj yeem hluav taws kub hydrant tso ua haujlwm nws lub luag haujlwm siab tshaj plaws hauv xwm txheej kub ntxhov.
Yog li ntawd, raws li technology txuas ntxiv mus ua ntej, kev txhim kho tsim nyog yuav tsum tau ua rau thev naus laus zis ntawm hluav taws kub.
