Dab tsi yog hydraulic slip rings siv rau?
Koj paub, kuv tau ua haujlwm nrog cov khoom siv teb tau ze li 15 xyoo tam sim no, thiab hydraulic slip rings yog ib qho ntawm cov khoom uas tsis muaj leej twg tham txog kom txog rau thaum muaj ib yam dab tsi phem heev. Lub hli tas los, peb muaj lub crane mus rau ntawm qhov chaw nres nkoj hauv Long Beach- hloov tawm tias lub nplhaib hydraulic hlais tau xau tau ntau lub lis piam, tab sis tus neeg teb xov tooj cia li khaws cov dej ntxiv. Thaum lub sij hawm lawv hu rau peb, muaj hydraulic roj nyob txhua qhov chaw thiab tag nrho cov kev sib hloov mechanism raug tua.
Lub hauv paus (tab sis tsis yog phau ntawv version)
Yog li hydraulic slip rings -qee zaum tib neeg hu lawv cov koom haum teb, hydraulic swivels, los yog rotating hydraulic pob qij txha, nyob ntawm seb leej twg koj tab tom tham nrog -lawv yog qhov tseem ceeb uas tso cai rau koj tso dej hydraulic los ntawm qhov chaw nres tsheb mus rau ib yam dab tsi uas yog spinning. Xav txog nws zoo li ... zoo, kev sib piv tsis zoo, tab sis xav txog kev sim ua lub thoob nrog dej thaum nws tig mus rau lub lauj kaub tais diav. Koj xav tau ib txoj hauv kev kom tau dej hauv qhov ntawd yam tsis muaj nws mus txhua qhov chaw.
Qhov chaw tshaj plaws uas kuv pom cov no? cranes. Kev tsim kho cranes, nkoj - mus rau - ntug hiav txwv cranes, mobile cranes, crawler cranes- yog tias nws nqa cov khoom hnyav thiab tig, tej zaum yuav muaj lub nplhaib hydraulic. Tab sis qhov ntawd tsuas yog khawb ntawm qhov chaw.
Qhov twg koj yeej pom lawv (thiab qhov twg lawv tawg)
Cua turbinesyog cov neeg siv loj ntawm hydraulic rings tam sim no. Lub suab tswj tshuab xav tau lub zog hydraulic los kho cov kaum sab xis, thiab pom tseeb tias lub nacelle tig nrog cov cua kev taw qhia. Kuv tau ua haujlwm ntawm Vestas V90 retrofit project rov qab rau xyoo 2019, thiab peb tau hloov cov hlua khi uas muaj tsawg dua 8 xyoo ntawm kev pabcuam lub neej. OEM spec hais tias 20 xyoo. Vim li cas? Ntsev cua corrosion los ntawm ntug hiav txwv installation. Tsis muaj leej twg xav txog qhov ntawd thaum lawv tab tom ua qhov kev xam pom thawj zaug.
Kev lag luam roj offshore siv lawv ntau heev thiab -drilling rigs, tshwj xeeb tshaj yog. Tab sis ntawm no yog ib yam dab tsi nthuav: hom kev ua tsis tiav yog txawv kiag li ntawm av -raws li daim ntawv thov. Peb muaj ib lub rig nyob rau hauv Gulf of Mexico qhov twg lub nplhaib nplhaib foob ua tsis tau txhua txhua 6-8 lub hlis. Tig tawm qhov sib xyaw ua ke ntawm cov cua sov (nws tau kub kub nyob ze ntawm lub laum pem teb) thiab cov khoom siv hluav taws xob tshwj xeeb uas lawv tau siv tau tawg rau Viton cov ntsaws ruaj ruaj. Hloov mus rau HNBR cov ntsaws ruaj ruaj thiab qhov teeb meem tau ploj mus. Tus nqi kwv yees li ntawm $ 12k ntxiv rau ib chav, tab sis thaum koj lub sijhawm poob qis yog $ 500k ib hnub, koj tsis mob siab rau.
Kev siv tub rog-radar systems, tank turrets, naval phom systems. Kuv tsis tuaj yeem tham txog ntau yam ntawm cov khoom no vim yog NDAs, tab sis cia kuv hais tias thaum koj xav tau tig 5-tuj radar array thaum siv cov kua dej hydraulic ntawm 3,000 PSI, engineering tau nthuav dav sai. Lub nplhaib plam rau cov ntawv thov no qee zaum muaj cov kev khiav tsis dhau, uas txhais tau tias yog ib qho channel tsis ua haujlwm, koj tau txais kev thaub qab. Kuv tau pom cov chav nyob nrog txog li 8 qhov kev ywj pheej hydraulic hauv ib lub tsev.
Cov cuab yeej kho mob yog lwm thaj chaw uas ua rau tib neeg xav tsis thoob. CT scanners thiab qee qhov tshwj xeeb kev phais neeg hlau siv hydraulic plam nplhaib. Daim ntawv thov CT scanner yog qhov nyuaj tshwj xeeb vim tias koj xav tau kev sib tw, kev co - kev sib hloov dawb thaum tswj xyuas cov kua dej ntshiab. Lub tshuab luam ntawv peb tau ua haujlwm nrog ntawm UCLA Medical yuav tsum tswj xyuas qhov sib xws hauv ± 2% thaum tig ntawm 180 RPM. Sim ua qhov ntawd nrog cov pa sib txuas hydraulic.
Kev sib tw engineering tsis muaj leej twg ceeb toom koj txog
Kev poob siab hla lub nplhaib plam yog ib qho ntawm cov khoom uas zoo li me me ntawm daim ntawv tab sis ua rau mob taub hau tsis kawg hauv kev teeb tsa tiag tiag. Peb tau pom cov tshuab uas cov kws tsim khoom suav txhua yam zoo kawg nkaus rau cov actuators thiab lub tog raj kheej, tab sis tsis nco qab kiag li suav nrog 150 PSI siab poob thoob plaws lub nplhaib. Qhov tshwm sim? Sluggish ua haujlwm, overheated twj tso kua mis, shortened tivthaiv lub neej.
Kub yog tus kws tua neeg uas ntsiag to. Hydraulic kua tau kub thaum nws ua hauj lwm nyuaj, thiab thaum koj yuam nws los ntawm qhov nruj clearances nyob rau hauv lub nplhaib npliag (peb tab tom tham 0.001 "mus rau 0.003" nyob rau hauv feem ntau designs), nws generates txawm ntau cua sov. Kuv tau ntsuas lub nplhaib ntiv nplhaib vaj tsev kub tshaj 180℃F ntawm excavators ua haujlwm hauv Arizona summers. Ntawm cov sijhawm ntawd, koj nyob ntawm ntug ntawm qhov hydraulic seals feem ntau tuaj yeem ua haujlwm ntev -lub sijhawm.
Tiag -cov khoom ntiaj teb uas tseem ceeb
Kev teeb tsa yog qhov teeb meem feem ntau pib. Lub nplhaib plam yuav tsum tau ua kom zoo nrog cov axis tig -feem ntau nyob rau hauv 0.005" TIR (tag nrho qhia tias runout). Kuv tau pom ntau qhov kev teeb tsa uas ib tus neeg tsuas yog bolted rau nws thiab hu nws zoo. Peb lub hlis tom qab, lawv xav paub vim li cas nws thiaj li tawg.
Auj, thiab ntawm no yog ib yam dab tsi uas tsis yog nyob rau hauv ib phau ntawv: lub mounting bolts yuav tsum tau retorqued tom qab thawj 50-100 teev ntawm kev ua hauj lwm. Thermal cycling ua rau tej yam teeb meem. Tsis muaj leej twg ua li no. Puas tau. Tom qab ntawd lawv liam rau cov chaw tsim khoom thaum nws pib tawm ntawm 2,000 teev es tsis txhob siv qhov ntsuas 10,000.
Port configuration tseem ceeb tshaj li cov neeg xav. Koj tuaj yeem tau txais cov hlua khi nrog sab ports, axial ports, lossis ob qho tib si. Rau ib daim ntawv thov crane, peb feem ntau siv cov chaw nres nkoj sab ntawm qhov chaw nres tsheb thiab cov chaw nres nkoj axial ntawm sab tig. Tab sis ntawm cua turbine qhov chaw nruj? Qee lub sij hawm koj tau daig nrog txhua yam ua haujlwm ntawm lub cev, txawm tias nws txhais tau tias qee qhov tsis zoo ntawm cov kav dej.
Tag nrho "kev tu-dawb" kev lag luam? Yog, feem ntau tsis muaj tseeb. Tseeb, lub nplhaib ntiv nplhaib nws tus kheej yuav tsis xav tau kev pabcuam li niaj zaus, tab sis hydraulic system nyob ib puag ncig nws yeej ua tau. Kev kis kab mob yog tus yeeb ncuab thib ib. Ib qho me me ntawm cov hlau los ntawm lub twj tso kua mis hnav, ib me ntsis ntawm cov roj hmab los ntawm cov hose deteriorating, thiab nws tuaj yeem tau qhab nia ntawm qhov sib khi. Peb tau khawb cov hlua khi tom qab pom cov hlau uas koj tuaj yeem pom tsis tshua pom nrog 10x loupe.
Daim ntawv thov kuv tseem tsis tau hais txog
Automated manufacturing-hloov rooj, teb indexing rooj, sib dhos fixtures. Cov no feem ntau khiav ntawm qis qis (800-1500 PSI) tab sis ntau dua lub voj voog. Kuv tau pom cov hlua khi ntawm cov tsheb sib dhos ua ke uas voj voog 10-12 zaug ib feeb, 24/7. Lub neej expectancy xam rau cov no yog txawv kiag li ntawm ib tug crane uas yuav tig ib zaug txhua ob peb feeb.
Steel mills siv hydraulic slip rings nyob rau hauv ladle turrets thiab nyob rau hauv ib co dov zeb configurations. Ib puag ncig yog lim hiam -kub, nplai, vibration, shock loads. Peb muab lub nplhaib 4-dhau hlaws rau lub nrum caster turret uas yuav tsum muaj sia nyob qhov kub txog li 200℃F ambient thiab qee zaus tshuaj tsuag dej. Kev cai stainless vaj tse, ceramic -coated rotor, tshwj xeeb high-temp seals. Siv sijhawm 7 xyoo ua ntej xav tau kev tsim kho dua tshiab. Cov neeg siv khoom zoo siab heev vim tias chav tsev dhau los tau siv sijhawm tsawg dua 3 xyoos.
Kev lom zem kev lag luam- cov khoom siv theem, rotating platforms, aerial rigs rau concerts thiab ua yeeb yam. Cov kev xav tau yog qhov nthuav vim tias koj xav tau kev lag luam txhim khu kev qha, tab sis lub voj voog ua haujlwm feem ntau yog lub teeb zoo nkauj. Qhov kev sib tw yog ntau ntxiv txog kev ntim khoom - ua kom nws me me thiab lub teeb thaum tseem tuav txaus txaus rau ntau lub tog raj kheej hydraulic.
Tej yam uas mus tsis ncaj ncees lawm (ib daim ntawv teev npe)
Kev foob tsis ua haujlwm yog 60% ntawm cov teeb meem peb pom. Kev xaiv cov khoom siv tsis raug, tuaj yeem ua paug, tuaj yeem ua rau lub siab spikes, tuaj yeem ua haujlwm tsis raug. Tej zaum kuj yog hmoov phem xwb.
Cov kabmob tsis ua haujlwm dhau los, txawm tias tsawg dua. Feem ntau nws yog vim ib tug neeg tsis ua raws li cov lus qhia muaj peev xwm. Tsuas yog vim lub nplhaib plam tuaj yeem tuav 3,000 PSI hydraulically tsis txhais tau tias nws tuaj yeem txhawb nqa 5,000 lb lub sijhawm thauj khoom. Xyuas cov chaw tsim khoom lub peev xwm nkhaus. Lawv nyob rau ib qho laj thawj.
Kev puas tsuaj cavitation-Kuv tau pom qhov no nyob rau hauv siab- cov ntawv thov ntws qhov twg qhov kev khiav ceev tau siab dhau lawm thiab lub zog hauv zos poob qis dua vapor siab. Koj xaus nrog cov npuas me me tsim thiab tawg, uas erodes cov hlau. Suab zoo li sandblasting los ntawm sab hauv. Kev daws yog feem ntau yog lub nplhaib loj dua lossis txo tus nqi ntws, tsis yog qhov uas tus neeg siv khoom xav hnov.
Hla -kev sib kis ntawm cov kab lus tsis tshua muaj tab sis muaj kev puas tsuaj loj thaum nws tshwm sim. Muaj 6- lub nplhaib hla hla ntawm daim ntawv thov cov cuab yeej siv hav zoov qhov twg lub foob tsis ua haujlwm sab hauv thiab tso cai rau siab - siab ntws mus rau hauv cov kab rov qab qis. Qhov tshwm sim ntawm qhov siab ua rau tawg tawm peb lub tog raj kheej hydraulic sib txawv. Hnub kim.
Tus nqi tiag tiag
Ib qho yooj yim 1-siv lub nplhaib rau 3000 PSI kev pabcuam yuav khiav tau $800-2000 nyob ntawm qhov loj thiab nta. Multi-passage units rau kev siv complex? Kuv tau pom cov lus tshaj $25,000 rau cov chav tshwj xeeb. Kev cai tsim nrog cov ntaub ntawv txawv? Ntuj yog qhov txwv.
Tab sis ntawm no yog qhov khoom - lub nplhaib ntiv nplhaib nws tus kheej feem ntau yog ib feem me me ntawm tag nrho cov nqi system. Ib lub crane yuav raug nqi $ 2 lab. Lub nplhaib ntiv nplhaib hydraulic yog tej zaum $ 5,000. Tab sis yog tias lub nplhaib tsis ua haujlwm, koj tuaj yeem saib ntawm $ 50, 000+ hauv cov nqi qis. Tias yog vim li cas peb ib txwm xav kom khaws ib qho khoom seem ntawm tes rau cov ntawv thov tseem ceeb, txawm tias cov neeg siv khoom feem ntau tsis xav hnov nws.
Qhov kuv qhia rau tib neeg thaum lawv tab tom qhia txog qhov system tshiab
Ua kom muaj peev xwm txaus rau koj qhov kev xav tau tiag tiag, tsis yog lub twj tso kua mis xwb. Kuv tau pom ntau lub nplhaib loj dhau qhov uas tus nqi ntws tiag yog ib nrab ntawm lub nplhaib ntiv nplhaib tuaj yeem ua tau. Koj xaus nrog qis tshaj tawm thiab muaj peev xwm stagnation teeb meem.
Xav txog kev siv tau. Koj puas tuaj yeem hloov lub nplhaib plam yam tsis muaj kev cuam tshuam tag nrho lub tshuab? Kuv tau ua haujlwm ntawm kev teeb tsa qhov twg hloov lub nplhaib ntiv nplhaib yuav tsum muaj 3-hnub crane disassembly. Tsis zoo.
Environmental sealing tseem ceeb. Yog tias koj nyob hauv ib puag ncig muaj plua plav, kev tswj kev sib kis yog qhov tseem ceeb. Marine ib puag ncig xav tau corrosion- cov ntaub ntawv tiv taus. Kub siab heev xav tau kev txiav txim siab tshwj xeeb rau cov ntaub ntawv foob thiab kev tshem tawm.
Thiab thov, thov qhia qhov tseeb hydraulic kua. Lub nplhaib nplhaib tsim tsim nyob ib ncig ntawm qee yam kua dej-viscosity, additives, hauv paus Tshuag. Kev siv random hloov kua yog thov kom muaj teeb meem.
Lub neej yav tom ntej (tej zaum)
Muaj kev txhim kho kev ua haujlwm tshwm sim ntawm tsis yog -hu rau magnetic coupling systems uas tuaj yeem hloov tau hydraulic rings hauv qee daim ntawv thov. Lub tswv yim yog siv cov hlau nplaum sib nqus los nqus cov kua dej los ntawm lub kaw lus kaw tsis muaj cov ntsaws ruaj ruaj. Nthuav tswv yim, tab sis kuv tsis tau pom nws ua haujlwm zoo tshaj li 1500 PSI tseem. Peb mam li pom.
Qee cov tuam txhab lag luam tab tom ua haujlwm ntawm cov pob khoom sib xyaw ua ke uas saib xyuas kev noj qab haus huv ntawm cov ntiv tes xoo - kub, siab, kev co. Predictive txij nkawm es tsis txhob reactive kho. Ua rau kev nkag siab hauv kev xav. Nyob rau hauv kev xyaum, feem ntau cov neeg muas zaub tsis xav them tus nqi them rau cov ntse version thaum lub hauv paus version yog ib nrab ntawm tus nqi.
Qhov tseeb yog hydraulic slip rings yog cov cuab yeej paub tab uas ua haujlwm zoo thaum siv tau zoo. Lawv yuav tsis ploj mus sai sai, txawm tias qee tus neeg hauv kev lag luam yuav thov txog "tag nrho- hluav taws xob" yav tom ntej. Hydraulics tseem muaj qhov zoo ntawm lub zog ceev thiab kev ntseeg siab uas nyuaj rau kev sib tw nrog hluav taws xob actuators, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.
