Cov khoom siv zoo ua kom muaj kev sib txuas zoo thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav thaum lub sijhawm ua haujlwm tseem ceeb. Kev xaiv cov hose couplings kom zoo, feem ntau yog ua los ntawm cov ntaub ntawv xws li hlau, tooj dag, lossis txhuas, yuav tsum sib xws hauv qhov loj me thiab xov kom ntseeg tau tias muaj kev sib txuas ruaj ntseg.
Kev nkag siab txog cov qauv txuas cov yeeb nkab tua hluav taws yog qhov tseem ceeb rau kev tua hluav taws zoo. Cov qauv no ua kom muaj kev sib haum xeeb thiab kev ntseeg siab, uas ua rau muaj kev nyab xeeb thaum lub sijhawm ua haujlwm. Cov neeg tua hluav taws yuav tsum xub siv cov khoom siv zoo uas ua tau raws li cov lus qhia tshwj xeeb.
- Kev ua raws li cov qauv no ua rau:
- Lub sijhawm sib txuas sai dua, tshwj xeeb tshaj yog nrog Storz couplings.
- Kev ua tau zoo txhim khu kev qha thaum muaj xwm txheej tseem ceeb.
- Lub sijhawm teb tau zoo dua, tiv thaiv hluav taws kom tsis txhob nce siab.
Los ntawm kev tsom mus rau kev nyab xeeb thiab kev sib haum xeeb, cov neeg tua hluav taws tuaj yeem txhim kho lawv txoj kev ua haujlwm zoo thiab ua kom muaj kev nyab xeeb ntawm lawv cov pab pawg thiab cov zej zog.
Cov Lus Nug Feem Ntau
Cov yeeb nkab hluav taws sib txuas yog dab tsi?
Cov kav dej tua hluav tawstxuas cov kav dej rau cov khoom siv, kom ntseeg tau tias cov dej ntws zoo lossis cov tshuaj tua hluav taws. Lawv muaj ntau hom, suav nrog NST, NPT, Storz, thiab Camlock, txhua tus tsim rau cov kev siv tshwj xeeb.
Vim li cas kev sib haum xeeb thiaj li tseem ceeb hauv cov kev sib txuas hluav taws kub?
Kev sib haum xeeb ua kom cov kev sib txuas thiab cov hoses ua haujlwm ua ke zoo. Cov kev sib txuas tsis sib xws tuaj yeem ua rau muaj kev xau, kev puas tsuaj rau cov khoom siv, thiab kev ncua sijhawm thaum muaj xwm txheej ceev, ua rau muaj kev nyab xeeb thiab kev ua haujlwm zoo.
