Thaum nws tawm los tshem tawm cov dej ntws tawm hauv npauj npaim li qub, muaj ntau txoj hauv kev uas tuaj yeem ua haujlwm. Nov yog qee cov tswv yim siv los txo qis lossis tshem tawm cov pa tawm hauv npauj npaim li qub:
Kev xaiv valve kom raug: Xaiv txoj cai ntawm npauj npaim valve rau daim ntawv thov tshwj xeeb yog qhov tseem ceeb. Ntau hom npauj npaim li qub, xws li resilient-seated thiab hlau-seated li qub, muaj ntau theem ntawm kev sib khi. Resilient-seated li qub feem ntau yog siv rau cov ntawv thov uas yuav tsum tau kaw nruj nreem, thaum cov hlau-seated li qub yog tsim rau high-temperature los yog abrasive media.
Kev xaiv cov khoom siv ntawm lub rooj zaum valve: Kev xaiv cov khoom siv lub rooj zaum valve yog qhov tseem ceeb rau kev ua tiav qhov kev sib khi ruaj khov. Cov rooj zaum ua los ntawm cov ntaub ntawv xws li elastomers (piv txwv li, EPDM, Nitrile, Viton) lossis PTFE (Polytetrafluoroethylene) muab cov khoom sib khi zoo heev thiab tuaj yeem pab txo qis.
Kev txhim kho thiab kev sib raug zoo: xyuas kom lub valve raug teeb tsa kom raug thiab ua kom zoo yog qhov tseem ceeb rau kev txo qis. Lub valve yuav tsum tau muab tso rau hauv ib txoj kev uas tso cai rau lub disc kom tiav kev sib cuag nrog lub rooj zaum thaum kaw. Kev sib dhos kom raug tuaj yeem tiv thaiv qhov khoob uas yuav ua rau muaj dej ntws.
Kev saib xyuas thiab tshuaj xyuas tsis tu ncua: Kev saib xyuas niaj hnub thiab kev tshuaj xyuas cov npauj npaim li qub yog qhov tseem ceeb txhawm rau txheeb xyuas cov teeb meem uas tuaj yeem ua rau xau. Qhov no suav nrog kev kuaj xyuas qhov hnav thiab tsim kua muag, cov ntsaws ruaj ruaj puas, lossis lwm yam cim ntawm kev puas tsuaj. Kev kho tam sim lossis hloov cov khoom faulty yog tsim nyog los tiv thaiv kom tsis txhob tawg.
Kev tswj torque: Kev tswj lub zog kom zoo thaum lub sijhawm ua haujlwm ntawm lub valve yog qhov tseem ceeb rau kev ua tiav lub foob zoo. Nyob rau hauv-tightening los yog over-tightening lub valve tuaj yeem ua rau cov pa tawm. Ua raws li cov chaw tsim khoom tau pom zoo torque qhov tseem ceeb thiab siv cov cuab yeej tsim nyog rau kev zawm lub valve tuaj yeem pab tswj lub foob kom raug.
Ntxiv cov ntsaws ruaj ruaj thib ob: Hauv cov ntawv thov uas yuav tsum muaj qib siab dua ntawm kev sib khi, tuaj yeem ua haujlwm ntxiv rau kev sib khi. Qhov no yuav suav nrog kev siv cov ntsaws ruaj ruaj, xws li O-rings, gaskets, lossis packing, los muab cov txheej txheem ntxiv ntawm kev tiv thaiv tawm.
Kev ntsuas siab: Kev ntsuas siab tsis tu ncua ntawm npauj npaim li qub tuaj yeem pab txheeb xyuas qhov muaj peev xwm xau. Qhov no suav nrog kev nias lub kaw lus thiab saib xyuas rau txhua qhov kev poob siab lossis pom qhov xau nyob ib puag ncig lub valve. Kev txheeb xyuas thiab daws cov dej xau tam sim yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm qhov system.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov txheej txheem no tuaj yeem txo qhov xau hauv npauj npaim li qub, ua tiav qhov xoom xoom xoom tsis tas yuav ua tau rau qee yam kev siv lossis kev ua haujlwm. Kev sab laj nrog cov tuam txhab valve thiab cov kws tshaj lij hauv kev lag luam tuaj yeem muab cov lus qhia ntxiv txog cov txheej txheem tshem tawm tshwj xeeb raws li daim ntawv thov.
