LNG fueling stations raug cais raws li cov chaw tuav tshuaj lom neeg thiab raug xaiv los ua cov chaw tseem ceeb rau kev nyab xeeb thiab kev tiv thaiv hluav taws. Liquefied Natural Gas (LNG) yog cov kua ua kua hauv lub xeev ntawm hydrocarbon sib tov muab los ntawm cov pa roj ntshiab huv; Nws yog lub cev muaj zog xws li tsis muaj xim, tsis muaj ntxhiab, thiab tsis yog - lom. Thaum siv los ua cov roj tsheb, LNG feem ntau muaj methane concentration ntau dua 90%, nrog rau cov lej ntawm ethane, propane, nitrogen, thiab lwm yam khoom siv. Raws li tus qauv atmospheric siab, LNG nthuav tawm qhov kub tsis tshua muaj siab heev - kwv yees li -162℃- thiab muaj cov kua dej - rau-gas expansion piv ntawm 600: 1; nws cov flammability ntau (los ntawm ntim) poob ntawm kwv yees li 5% thiab 15%. Txhawm rau kom ua tiav cov txheej txheem kev ua haujlwm ntawm LNG cov chaw nres tsheb roj thiab txhim kho kev nyab xeeb ntawm lub tsheb refueling, peb thov kom txhua tus neeg tsav tsheb nruj me ntsis ua raws li cov cai tswj kev nyab xeeb thiab kev txwv tsis pub, yog li tiv thaiv kev nyiam ntawm txhua tus neeg koom nrog. Yog li ntawd, cov neeg tsav tsheb refueling ntawm lub chaw nres tsheb LNG yuav tsum nruj me ntsis ua raws li cov cai hauv qab no:
1. Kev haus luam yeeb yog nruj me ntsis txwv tsis pub nyob rau hauv qhov chaw nres tsheb filling.
2. Cov tsheb uas nkag mus rau hauv qhov chaw nres tsheb yuav tsum maj mam thiab ceev faj, ua raws li kev txwv ceev ntawm 5 km / h.
3. Lub tsheb nkag mus rau refuel yog txwv tsis pub nqa cov neeg ua haujlwm lossis cov neeg caij tsheb mus rau hauv chaw nres tsheb; cov neeg zoo li no yuav tsum tau tawm mus sab nraud ntawm qhov chaw nres tsheb thiab tsis raug tso cai nyob hauv lub tsheb thaum nws tab tom refueled.
4. Thaum lub sij hawm refueling, lub cav tsheb yuav tsum tau muab tshem tawm, tag nrho cov onboard hluav taws xob cov cuab yeej yuav tsum tau disabled, thiab txhim khu kev qha braking ntsuas (xws li koom tes braking) yuav tsum tau siv.
5. Kev saib xyuas lub tsheb raug txwv nruj nyob rau hauv qhov chaw nres tsheb; Yog tias lub tsheb muaj kev tsis ua haujlwm, nws yuav tsum tau txav mus rau sab nraud ntawm qhov chaw nres tsheb rau kev kho.
6. Cov neeg tsav tsheb thiab tsis yog- cov neeg ua haujlwm tshwj xeeb raug txwv tsis pub khiav cov khoom siv roj; Tsis tas li ntawd, refueling yog txwv tsis pub rau ib lub tsheb gas cylinders uas muaj teeb meem kev nyab xeeb.
7. Cov neeg ua haujlwm nkag mus rau hauv qhov chaw nres tsheb yuav tsum tsis txhob hnav khaub ncaws hluavtaws lossis khau khiab nrog cov hlua hlau thaum mus txog lossis nkag mus rau thaj chaw uas raug xaiv los ntawm kev tawg.
8. Lub tsheb thiab cov neeg ua haujlwm tam sim no rau refueling yog txwv tsis pub nkag mus rau hauv chaw nres tsheb cov chaw tsim khoom yam tsis tau kev tso cai meej.
9. Cov tsheb uas nkag mus rau hauv refueling yuav tsum ua raws li cov lus qhia ntawm cov chaw nres tsheb, nres nyob rau hauv lub cheeb tsam ntawm qhov kev ncua deb ntawm tsawg kawg yog 50 centimeters los ntawm lub refueling kob, thiab nkag mus thiab tawm ntawm lub chaw nres tsheb cheeb tsam raws li tau hais tseg, nruj me ntsis txwv tsis pub tsav tsheb tawm tsam kev khiav tsheb.
10. Cov tsheb thauj mus los yuav tsum tsis txhob khiav dhau, rub, lossis khoov cov hoses refueling; cov neeg ua haujlwm yuav tsum tsis txhob nqis los ntawm cov hoses lossis ua rau lawv lub cev sab nraud.
11. Cov tsheb uas nrhiav refuel yuav tsum muaj daim ntawv pov thawj ntawm kev kuaj xyuas lub tog raj kheej / ntim cov khoom tsim nyog; txwv tsis pub, tus neeg tsav tsheb chaw nres tsheb muaj cai tsis kam txais kev pabcuam.
12. Tom qab ua tiav cov refueling, lub cav tsheb yuav tsuas yog rov qab pib dua tom qab lub hose siab tau tag nrho vented thiab lub refueling nozzle tau ruaj ntseg disconnected.
13. Rau kev nyab xeeb ntawm koj tus kheej thiab lub chaw nres tsheb filling, thov tsis txhob nres koj lub tsheb hauv qhov chaw nres tsheb rau lub sijhawm ntev.
