Kev txuas chav dej rau hauv qhov dej phwj yog txheej txheem yooj yim. Yog tias koj xav txuag ntawm kev ua haujlwm ntawm tus kws kho qhov muag, koj tuaj yeem sim ua koj tus kheej. Hmoov zoo, cov chaw tsim khoom ntawm cov kav dej fittings muaj ntau txoj kev xaiv rau adapters. Txhawm rau kom yooj yim thiab ntseeg tau ua qhov kev sib txuas ntawm cov ntsiab lus nyob nrog kev sib txheeb ze rau ib leeg, siv ib qho eccentric.
dab tsi yog chav dej eccentric
Ib qho eccentric (cuff) yog ib feem ntawm kev sib txuas fittings nyob rau hauv daim ntawv ntawm cov yeeb nkab, cov npoo ntawm uas yog offset txheeb ze rau ib qho axis. Qhov kev tsim no tso cai rau koj kom muaj qee qhov kev ywj pheej thaum txhim kho chav dej, yog tias nws lub qhov hluav taws xob thiab lub qhov dej tsis sib haum. Alignment yog tiav los ntawm tig lub cuff hnav ntawm lub nozzle.
Chav dej eccentrics yog ua nyob rau hauv qhov sib txawv ntev nrog tus qauv txoj kab uas hla ntawm lub qhov txuas. Roj hmab cuffs muaj corrugated nto ntawm cov ntsiab lus ntawm kev sib txuas rau lub nozzles. Qhov no muab kev ruaj ntseg zoo dua. Thiab cuffs ua los ntawm yas yog nruab nrog tshwj xeeb roj hmabgaskets.
Eccentrics yog siv los qhia cov kav dej nyob hauv tib lub dav hlau. Tab sis yog tias lub kaum sab xis ntawm qhov sib txawv me me, cov yas cuffs tau siv, sib txawv ntawm qhov corrugated, nyob rau hauv thaj tsam ntawm koj tuaj yeem khoov me ntsis.
Thaum twg nws yooj yim siv lub cuff
Ntxiv rau kev siv lub cuff, muaj lwm txoj hauv kev rau kev sib txuas ntawm chav dej rau cov kav dej, tab sis muaj qee lub sij hawm thaum lub chav dej eccentric nrog ib qho offset yog tib qho kev xaiv muaj los ua kev sib koom ua ke. Raws li txoj cai, qhov no tsuas yog tshwm sim nrog ob hom chav dej: kab rov tav thiab oblique qhov hluav taws xob. Cov laj thawj rau misalignment ntawm axes tuaj yeem ua raws li hauv qab no:
- Hloov lub qhov tso quav qub nrog ib qho tshiab thiab tsis muaj peev xwm xaiv tus qauv uas zoo sib xws hauv qhov ntev geometric.
- Hloov cov theem hauv pem teb thaum tso cov vuas, ua rau qhov sib txawv ntawm qhov siab ntawm qhov hluav taws xob thiab qhov nkag ntawm cov kav dej.
- Tsis muaj peev xwm tswj tau kev sib raug zoo nrog qhov pib hloov chaw ntawm cov kav dej phwj tuaj hauv ntau lub tsev.
- Kev ua yuam kev hauv kev tsim kev sib txuas lus.
Txhua qhov xwm txheej no, kev siv eccentric yog qhov cuam tshuam, yog tias qhov hloov pauv tsis tshaj tsib centimeters.
Chav dej Cam: Qhov ntau thiab tsawg
Eccentric hom tso quav couplings muaj lub qhov taub ntawm 100mm. Qhov no tso cai rau lawv tso ncaj qha rau hauv lub qhov (socket) ntawm cov kav dej phwj tuaj yam tsis muaj qhov hloov pauv ntxiv.
Cuff length nws txawv. Cov roj hmab luv tshaj plawstxwv rau 150 mm. Plastic cuffs tuaj yeem ncav cuag qhov loj ntawm 250 mm. Nws yog qhov ua tsis tau zoo los ua kom ntev txuas ntxiv, txij li nws ib txwm muaj peev xwm ua kom cov kav dej phwj tuaj yeem mus rau lub xeev xav tau siv lub qhov hluav taws xob yas.
Lwm yam txuas txuas txuas
Nrog rau eccentrics, muaj lwm yam kev sib txuas:
Plastic adapters, khoov thiab nozzles. Lawv feem ntau yog siv rau coaxial articulation ntawm qhov cuab lub zog, los yog nyob rau hauv ntau lub ces kaum ntawm divergence ntawm nozzles. Siv cov kev sib txawv ntawm kev khoov, piv txwv li, ob lub kaum 45-degree, koj tuaj yeem ua rau chav dej hauv tsev eccentric. Nws yuav ua tsis zoo rau lub Hoobkas qauv tshwj tsis yog hauv kev zoo nkauj. Hais txog kev ntseeg tau thiab kav ntev, qhov no yog qhov kev xaiv zoo tshaj plaws
- Corrugations, corrugated cuffs. Cov pob qij txha no yog siv rau hauv cov xwm txheej nyuaj, nrog qhov sib txawv ntawm qhov sib koom ua ke mus txog 90 degrees thiab siab dua. Corrugation tuaj yeem hla txhua qhov cuam tshuam. Qhov tsis zoo ntawm kev sib txuas yog nws qhov fragility. Cov phab ntsa nyias nyias hauv thaj chaw khoov tuaj yeem tawg, thiab cov av qeeg yooj yim nkag rau ntawm sab hauv vim yog cov tav.
- Ntxuam kav. Cov fittings no haum rau cov pob qij txha ncaj. Lawv tau txais txiaj ntsig zoo los ntawm cov khoom siv uas lawv tau tsim: faience, porcelain, daim plooj (porcelain). Cov khoom zoo li no yuav tsum tau ua tib zoo saib xyuas vim nws qhov tsis yooj yim.
- Ncaj roj hmab lossis yas cuffs.
Kauj ruam los ntawm kauj ruam kev teeb tsa chav dejntawm eccentric
Piv txwv li, xav txog kev txhim kho lub tais tso quav tso rau hauv chav dej uas tau hloov kho tshiab, qhov twg cov vuas hauv pem teb thiab cov phab ntsa tau hloov tag nrho thiab tsuas muaj qhov tawm ntawm cov kav dej. Nyob rau hauv cov ntaub ntawv qhov chaw, muaj ib tug axis offset ntawm cov txuas txuas.
Cov txheej txheem tau muab faib ua ob peb kauj ruam:
- Txhim kho lub tso quav tso rau hauv nws txoj haujlwm tas mus li thiab qhia cov ceg nrog cov cim dub ncaj qha rau hauv pem teb pobzeb. Mark Mounting qhov.
- ntsuas qhov kev ncua deb ntawm cov kav dej, ntxiv rau 5cm rau txhua sab kom haum rau chav dej eccentric.
- Yuav yog qhov ntev ntawm eccentric thiab automotive sealant (nws ua haujlwm zoo dua ntawm kev sib khi lub seam dua li silicone).
- Txav lub qhov tso quav mus rau sab, ntxig cov eccentric rau hauv lub qhov (socket) ntawm cov kav dej. Lawv rov qab lub tais tso rau hauv nws qhov chaw thiab, tig lub eccentric nyob rau hauv ib lub voj voog, ua tiav qhov tseeb nkag ntawm lub tais tso quav tso rau hauv nws.
- Nrog rau tus cim rau ntawm qhov eccentric thiab lub qhov (socket) ntawm cov kav dej phwj tuaj, ib qho kev sib tw ua kom muaj cov lus qhia rau txoj haujlwm ntawm lub ntsiab.
- Tshem tawm lub tais tso quav, tshem tawm cov coupling ntawm cov yeeb nkab, laum mounting qhov thiab nruab cov dowels yas hauv lawv.
- Nyob rau hauv ib ncig ntawm cov kav dej phwj tuaj (ntawm qhov chaw uas eccentric haum), ib txheej ntawm sealant yog siv thiab lub tes tsho yog ntxig, ua kom cov cim.
- Thov ib txheej ntawm sealant rau hauv chav dej ntws thiab nruab qhov tom kawg rau hauv qhov chaw ruaj khov, ntxig rau 100 mm chav dej eccentric.
- Cia lub sealant zaum 30 feeb thiab xyuas qhov ntws los ntawm kev nchuav ob peb lub thoob dej rau hauv chav dej. Txhawm rau tswj cov dej xau, ib daim ntawv dawb muab tso rau hauv pem teb hauv qab lub cuff.
- Yog tias txhua yam zoo thiab tsis muaj qhov xau, ntsia hlau lub tais tso rau hauv pem teb nrog cov ntsia hlau, so cov kab cim nrog cawv.
Nws yog ib qho tseem ceeb uas yuav tau txiav txim siab tias koj tuaj yeem ua tiav txoj hlua ruaj khov los ntawm kev siv cov sealant nkaus xwb rau qhov chaw qhuav.
Txhob muab roj hmab cuff
Thaum lub sijhawm ua haujlwm, qee zaum eccentrics tsis ua haujlwm thiab pib xau ya raws. Qhov no tuaj yeem tshwm sim vim kev laus ntawm cov roj hmab thiab poob ntawm nws elasticity. Txhawm rau hloov lub cuff nrog ib qho tshiab, ua cov haujlwm hauv qab no:
Yaug lub hauv caug nrog ob peb lub thoob dej, tshem cov kua uas seem hauv lub hauv caug
- Nrog rau cov ntaub ntawv hlau, txiav lub cuff hauv ib nrab, tshem tawm cov ntsia hlau uas tuav cov ceg tso quav tso rau hauv pem teb thiab lub raj los ntawm lub tank tso dej (yav tas los tua cov kais dej). Lub tsev tso quav tso rau ntawm sab.
- Tshem tawm cov khoom seem ntawm lub cuff siv los ntawm lub tais tso quav thiab cov kav dej. Ua tib zoo tshem tawm cov txheej txheem qub qub thiab cov ntsev tso rau hauv lub sijhawm ua haujlwm ntawm cov kav dej.
- Nruab lub chav dej tshiab eccentric nrog qhov sib txawv ntawm 100 hli raws li tau piav qhia hauv tshooj dhau los ntawm kab lus.
Kho eccentric yam tsis hloov
Kev cuam tshuam ntawm kev sib txuas ntawm lub caj dab yuav tshwm sim thaum lub sijhawm nws hloov pauv nyuaj lossis ua tsis tau. Txhawm rau tshem tawm cov xau thiab txuas ntxiv tsis mobsiv chav dej, siv ntau txoj hauv kev:
- Kev sib khi nrog ntaub. Lawv muab ib daim ntawm cov paj rwb tuab thiab txiav mus rau hauv ib daim hlab 5 cm dav. Pib los ntawm cov yeeb nkab tso quav, cov ntaub yog qhov txhab (los ntawm hom rwb thaiv tsev winding) hla tag nrho cheeb tsam mus txog rau cov kav dej phwj, ua ob peb lem ntawm nws thiab. Ruaj ntseg cov npoo nrog hluav taws xob daim kab xev. Tag nrho saum npoo ntawm qhov teeb meem yog pleev xim rau nrog roj pleev xim. Cov xim raug tso cai kom qhuav.
- Kho nrog elastic bandage. Lawv siv tib txoj cai winding, tsis muaj kev pleev xim tom ntej.
- Putty nrog automotive sealant. Txoj kev siv yog tias lub cuff eccentric rau lub tais tso quav tso ntawm qhov sib tshuam. Qhov sib koom ua ke yog ntxuav thiab qhuav. Qhov chaw kho mob tau ntim nrog cov sealant thiab tso cai kom qhuav rau ib nrab teev.
Zaj lus
Kho lossis hloov qhov sib txuas nrog lub tais tso quav tso tau yooj yim dua thiab tsis tuaj yeem nrog cov ntxhiab tsw tsis zoo los ntawm cov kav dej, nws raug nquahu kom nruab ib lub adapter nrog lub ntsuas hluav taws xob nyob rau sab tom kawg. Qhov kev ntsuas no tseem yuav tiv thaiv kev nkag mus ntawm cov dej phwj tuaj rau hauv thaj chaw los ntawm qhov chaw nruab nrab hauv ntau lub tsev yog tias lub riser tau txhaws.
