Hloov lub voj voog rau LPG Loading Arm Swivel Joint Seal Rings (Industry Standard; Condition-Dependent)
I. Lub voj voog hloov lub hauv paus (kev ua haujlwm tsis tu ncua; LPG / Propane / Butane; Tsim siab: 2.5 MPa)
Yam yuavtsum tau kawm uantej: Daim ntawv thov txhua hli ntawm nruab nrab -cov roj sib xws; tsis muaj kev cuam tshuam lub cev / kev puas tsuaj; tsis muaj qhov txawv txav.
Cov Txheej Txheem Kev Ua Haujlwm (Inland cia chaw; Tsawg dua lossis sib npaug li 20 lub sijhawm thauj khoom / tshem tawm ib hnub; ambient kub)
Yuav tsum tau hloov lub foob tag nrho txhua 18-24 lub hlis.
Kev ua haujlwm hnyav (Lub voj voog ib nrab rau 12 lub hlis yog * ib qho * ntawm cov hauv qab no siv):
Continuous 24-hour loading/unloading; >25 lub tsheb thauj khoom / hnub;
ntug hiav txwv ib puag ncig nrog ntsev tsuag; nthuav tawm sab nraum qhov chaw tsis muaj chaw nyob;
Ntev qis- qhov kub thiab txias raug rau lub caij ntuj no (hauv qab -10 degree);
Nruab nrab muaj leej faj los yog siab impurity; nquag me me sab nraud seepage;
Cov xwm txheej ceev ceev tsis tu ncua; nquag yuam twisting ntawm caj npab; nquag disassembly / reassembly ntawm qhov sib koom ua ke.
Kev ua haujlwm tsis sib xws (tsawg dua lossis sib npaug li 3 hnub ntawm kev ua haujlwm hauv ib lub lis piam; lub sijhawm tsis ua haujlwm ntev)
Lub sijhawm ntev tshaj plaws tsis pub tshaj 30 lub hlis;
⚠️ Txawm tias tsis pom qhov xau, sealing roj hmab ua rau muaj kev laus thiab deformation mus tas li nyob rau hauv ntev - lub sij hawm zoo li qub compression; lub sijhawm hloov pauv tsis tuaj yeem txuas ntxiv mus tas li.
II. Ntsiab Cai:Lub voj voog sawv cev rau qhov * siab tshaj * txwv rau kev hloov pauv; nres ua haujlwm thiab hloov tam sim yog tias muaj cov hauv qab no tshwm sim-tsis txhob tos rau hnub teem tseg:
Nruam sab nraud seepage, Frost tsim, los yog combustible gas detector ceeb toom ntawm qhov sib koom ua ke; kev xau tseem nyob txawm tias bolt nruj;
Disassembly nthuav tawm lub nplhaib sib khi tawv, blistering, tawg, khawb, khoom tawg, lossis poob ntawm elasticity;
Cov kab nrib pleb pom ntawm daim iav zawv zawg- ua tiav qhov chaw thaum kuaj xyuas (qhia tau tias muaj qhov ua tau zoo ntawm kev foob lub nplhaib puas);
Keeb kwm ntawm kev sib txhuam qhuav los yog ua haujlwm ntev yam tsis muaj roj.
III. Cov ntsiab lus tseem ceeb ua haujlwm
Yuav tsum hloov * tag nrho cov teeb *; Hloov tsuas yog ib lub nplhaib foob raug txwv.
Ib txhij hloov lub ntsiab zawv zawg foob nplhaib, auxiliary foob nplhaib, thiab plua plav foob; sib tov tshiab thiab qub seals feem ntau ua rau tsis zoo sealing nto kev sib cuag.
Distinguishing lub neej kev pab cuam los ntawm cov khoom
FKM (Fluoroelastomer) cov ntsaws ruaj ruaj (Standard for LPG): Ua raws li cov voj voog teev saum toj no;
NBR (Nitrile Roj Hmab): Tsis zoo tiv thaiv o tshwm sim los ntawm liquefied hydrocarbons; nruj me ntsis txwv tsis pub siv rau hauv LPG loading / unloading arm swivel pob qij txha. Ib qho kev xav tsis zoo ntawm cov lag luam yog: "Yog tias tsis muaj qhov xau, tsis tas yuav hloov pauv."
Lub nplhaib hnav yog ib hom kev ua haujlwm tsis zoo, nrog kev hnav sab hauv feem ntau pom ntawm qhov muag liab qab. Muab hais tias LPG yog qhov nruab nrab uas muaj hluav taws kub thiab tawg heev - ua rau muaj kev pheej hmoo loj heev thaum muaj qhov tshwm sim sai sai, loj heev - cov qauv kev nyab xeeb petrochemical tswj hwm kev tiv thaiv kev hloov pauv es tsis yog kev cia siab rau kev saib xyuas zoo xwb.
IV. Pom zoo rau -Site Management Practices
Tsim kom muaj lub log txij nkawm rau cov pob qij txha sib txuas los sau cov hnub ua haujlwm, lubrication keeb kwm, thiab cov dej xau;
Ua hauv - kev tshuaj xyuas qhov tob txhua rau lub hlis - suav nrog kev kuaj pom qhov pom thiab kev ntsuam xyuas ntawm kev xav hloov- los ua lub hauv paus rau kev kwv yees thaum lub sijhawm hloov pauv;
Ua kom tiav cov khoom sib khi ua tiav- cov khoom siv zoo ua ntej ntawm lub sijhawm hloov pauv kom tsis txhob muaj lub sijhawm poob qis uas tshwm sim los ntawm qhov tsis muaj qhov chaw thaum muaj xwm txheej ceev.
