Making hloov mus rau kev sib txuas nrog elastomeric O-ring seals yog qhov tseem ceeb hauv kev lag luam niaj hnub no. Tab sis ua ntej ua raws li txhua tus neeg ua, nws yog ib qho tseem ceeb uas koj nkag siab txog kev sib txuas kom siv tau zoo hauv koj daim ntawv thov, tshwj xeeb tshaj yog vim tias cov tshuab hydraulic siv ntau hom fittings thiab adapters nyob rau hauv ntau txoj kev sib khi thiab cov ntaub ntawv xov.
Vim li cas siv flange haum
Hydraulic kev sib txuas yog siv los tiv thaiv kev xau thiab lwm yam kev ua tsis tiav hauv cov ntawv thov siab, tshwj xeeb tshaj yog nyob rau hauv qhov loj. Flanges yog siv thaum tsim kom yooj yim kev sib txuas ntawm hose, raj thiab yeeb nkab. Nws yog qhov uas yuav tsum tau yooj yim tshaj plaws nyob rau hauv lub system.
Flange kev sib txuas feem ntau yog siv rau hauv cov ntawv thov tshwj xeeb tshwj xeeb thaum siv cov yeeb nkab lossis tubing nrog OD tshaj 7/8 hauv. ruaj ntseg flange haum los yog seem ntawm cov yeeb nkab. Flanges tseem tuaj yeem raug tshem tawm kom yooj yim rau kev hloov kho lub cev, ntxuav lossis tshuaj xyuas nws. Qee qhov flanges kuj tseem tuaj yeem txuas mus tas li ua ke los yog mus rau qhov chaw nres nkoj ntawm cov khoom xws li lub cev muaj zog lossis qhov chaw nres nkoj valve. Feem ntau, lub flanged sib koom ua ke yog tsim los ntawm bolting ob flanges ua ke nrog lub gasket nyob rau hauv-nruab nrab kom muaj kev ruaj ntseg foob.
Yog vim li cas rau lawv siv yog txuas cov chaw nres nkoj ncaj qha tsis tas yuav tsum siv threaded connectors lossis adapters. Lawv yog cov zoo rau cov cheeb tsam nyuaj mus cuag, ceev ceev thiab kev siv hydraulic nruj. Flange fittings kuj yog qhov kev xaiv zoo tshaj plaws rau hose kawg kev sib txuas uas muaj khoov thiab raug rau siab lateral zog.
Tab sis ua ntej txhua lub hose, raj thiab cov yeeb nkab sib sau ua ke, nws yog ib qho tseem ceeb kom paub qhov kawg ntawm cov chaw nres nkoj thiab cov khoom sib txuas. Nws pab kom ntseeg tau tias kev sib txuas yuav muaj kev nyab xeeb. Lub Society of Automotive Engineers (SAE) thiab International Organization for Standardization (ISO) pab koj txheeb xyuas cov teeb meem tshwj xeeb thaum ua cov kev sib txuas no.
Flange fittings nrog O-rings ua kom tsawg tsawg thaum lawv sib phim kom raug. Lub foob elastomeric yog nyob rau hauv qhov zawj kom kaw cov kua dej. Cov fittings no suav nrog SAE ncaj xov, ntsej muag foob, ISO 6149, SAE J518 (Code 61 thiab Code 62) flanges, thiab lwm yam.
Hom flange fittings thiab cov khoom siv:
SAE J518 flange fittings- SAE J518 yog siv thoob plaws ntiaj teb los txuas txoj kab uas hla loj dua thiab cov yeeb nkab hauv cov kua hluav taws xob kev lag luam. Tshem tawm ntawm qhov loj me, SAE J518 flanges yog sib hloov nrog ISO 6141, DIN 20066 thiab JIS B 8363. Cov flanges no tuaj hauv ob chav kawm siab. Tus qauv yog ISO6162, thiab nws suav nrog SAE Code 61 thiab Code 62. Qhov no yog qhov tseem ceeb vim tias yog flange tsis raug, koj tuaj yeem muaj teeb meem loj hauv koj lub cev vim SAE Code 62 ua haujlwm txog 6,000 psi thiab SAE Code 61 tuav txog 3,{13}} txog 5,{15}} psi.
Captive flange clamps- Captive flange clamps feem ntau siv thaum txuas cov raj, kav dej lossis hoses. Lawv plam dhau lub raj flared thiab tau yooj yim txuas nrog mating flange lossis cov khoom siv. Cov hom clamps no feem ntau yog siv nrog MJ-flange ncaj fittings vim hais tias muaj ib tug du clearance swb hla lub haum thiab zaum ntawm lub taub hau flange.
Split flange clamps - Split flange clamps yog tsim los ntawm ob daim ntawv sib txuas, haum ruaj ntseg ua ke nrog cov txiv ntseej thiab bolts. Txij li thaum lawv muaj ob daim, cov hom clamps no yog siv los txhawb qhov chaw tsis muaj zog hauv cov raj thiab cov yeeb nkab. Lawv tuaj yeem ntxiv qhov txuas qhov twg cov flanges tsoos tsis tuaj yeem. Koj tuaj yeem yuav cov flange haum clamps hauv cov khoom siv (xws li Code 61 lossis Code 62). Cov khoom siv tuaj yeem suav nrog ob daim, O-ring ntsej muag foob (ORFS) thiab plaub bolts thiab ntxhua khaub ncaws.
Cov hom flange fittings thiab cov khoom siv no feem ntau yuav tsis yooj yim dua thaum muaj kev sib faib khoom ntawm clamping nyob ib ncig ntawm lub taub hau flange.
ORFS fittings yog txhim khu kev qha
Fittings thiab cov khoom sib dhos yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig hnyav, xws li corrosive offshore daim ntaub ntawv rau huab cua kub thiab siab hloov pauv. ORFS fittings yog txhim khu kev qha vim lawv suav nrog elastomeric foob O-rings. Nws yog ib qho kev xaiv zoo tshaj plaws rau kev sib txuas tsis muaj xau.
Raws li lub npe qhia, ORFS, lossis (O-ring Face Seal) fittings suav nrog O-ring ntawm lub ntsej muag ntawm qhov haum. Ua rau SAE J1453 tus qauv, ORFS kev sib txuas feem ntau yog tsim los ntawm cov pa roj carbon, npib tsib xee plated carbon thiab stainless hlau thiab feem ntau siv cov ntsaws ruaj ruaj, xws li Buna-N lossis Viton, 90 Durometer O-rings uas zaum hauv qhov zawj ntawm lub ntsej muag haum. .
Thaum lub o-ring compresses ntawm lub ntsej muag o-ntiv nplhaib ntawm lub ntsej muag haum thiab lub ntsej muag tiaj tus ntawm lub mating ORFS haum los yog lub raj tsim, lub foob foob yog tsim. Thaum kev sib txuas yog nruj, O-ring compresses tiv thaiv lub ntsej muag tiaj tus ntawm mating haum lossis raj.
Thaum kev cai tsim stainless muaj, tus qauv ORFS fittings thiab lub ntsej muag lub ntsej muag yog ua los ntawm cov hlau plated lossis stainless hlau. Ua ntej tsim los rau kev tsim kho, ORFS fittings yog tam sim no siv rau lwm yam kev siv tsheb thauj mus los. ORFS fittings yog qhov zoo rau kev kub siab uas yuav raug flexing lossis siab surges, xws li kev tsim kho, kev ua liaj ua teb, roj thiab roj, mining thiab kev lag luam kev lag luam siab. Lawv kuj yog cov nyiam kev sib txuas rau kev co siab vim tias O-ring yog mos thiab absorbs poob siab zoo dua li cov hlau-rau-hlau kaw fittings.
Ua rau hydraulic system to
Yog tias koj muaj hydraulic system to, paub tias nws tsis tshua muaj tshwm sim los ntawm kev haum nws tus kheej. Lub hauv paus tseem ceeb rau kev xau system suav nrog kev teeb tsa tsis raug, tsim qauv tsis zoo, cov khoom siv tsis zoo thiab kev tsim txom lub cev.
Nws yog ib qho tseem ceeb uas koj nkag siab qhov no vim tias qhov tshwm sim tuaj yeem raug nqi. Tsis tsuas yog nws kim heev los ntawm cov khoom siv thiab kev ua haujlwm, tab sis nws kuj raug nqi los ntawm qhov poob ntawm cov dej sawv ntsug. Yog tias kev ua haujlwm tau ua haujlwm 24 teev hauv ib hnub thiab cov roj hydraulic raug nqi $ 25 ib nkas loos, tus nqi ntawm cov dej xau tuaj yeem yog qhov tseem ceeb. Kev tsim qauv yog thawj qhov chaw pib thaum tiv thaiv kev xau. Cov khoom tsim nyog yuav tsum raug xaiv los txo qhov tshwm sim ntawm kev xau thiab kev sib txuas tsis ua haujlwm. Thaum tiv thaivg hydraulic system to, tshuaj xyuas cov hauv qab no:
Daim ntawv thov- Koj ib puag ncig txiav txim siab tsim thiab xaiv. Piv txwv li, stainless hlau los yog lwm yam txheej txheej tiv thaiv tuaj yeem txuas ntxiv lub neej kev pab cuam nyob rau hauv ib puag ncig corrosive. Txawm tias qhov kev xaiv ntawm cov khoom siv O-ring yuav tsum ua raws li cov txheej txheem. Ib qho fluorocarbon lossis lwm yam khoom siv yuav tsum tau teev tseg dhau Buna-N hauv qee daim ntawv thov
Siab- Qhov ntsuas lub zog ntawm lub flange haum lub rooj sib txoos yuav tsum sib npaug los yog siab tshaj qhov system lub siab. Fittings raug ntsuas ntawm 4: 1 tus qauv tsim, uas siv rau kev ua haujlwm ib txwm muaj rau kev tiv thaiv ib puag ncig hydraulic thiab mechanical shock. Rau kev vibration hnyav thiab poob siab, "de-rating factor" yuav tsum tau siv ncaj qha rau lub zog dynamic ntawm qhov haum.
Kub- Kev khiav hauj lwm kub rau fittings thiab O-ring seals yog nyob ntawm cov plating thiab cov hlau thiab cov ntaub ntawv foob.
Nrhiav qhov tsim nyog rau koj daim ntawv thov
If koj tab tom xaj cov flange fittings zoo thiab ORFS cov khoom los ntawm cov chaw tsim khoom muaj koob npe, ces koj yuav tsum nyob hauv qhov chaw zoo dua li feem ntau. Nws yog ib qho tseem ceeb rau kev koom tes nrog koj tus neeg muag khoom kom paub tseeb tias koj xaiv qhov zoo rau koj daim ntawv thov.
Cov khoom tsim nyog muaj rau koj qhov system. Tsuas yog xyuas kom tseeb tias koj tab tom nrhiav cov khoom lag luam zoo tshaj plaws los ntawm cov tuam txhab muaj ntawv pov thawj uas tuaj yeem teb sai sai rau koj cov kev xav tau loj hlob thaum tseem ua tau raws li cov qauv kev lag luam. Kev tsim thiab ua haujlwm ntev ntawm txhua qhov flange haum thiab cov khoom siv yuav ua kom muaj kev pabcuam ntev, txawm tias nyob rau hauv ib puag ncig corrosive thiab tsim txom.
