Cov kev xav tau ntawm kev txhim kho thiab kev ceev faj rau cov kav dej hydraulic, cov khoom siv hydraulic thiab cov khoom siv hauv cov tshuab hydraulic
Xyoo 2023-10-26Lub installation ntawm hydraulic system, nrog rau kev teeb tsa ntawm hydraulic pipelines, hydraulic Cheebtsam, auxiliary Cheebtsam, thiab lwm yam, yog qhov tseem ceeb rau kev sib txuas ntawm ntau yam los yog cov khoom siv ntawm lub cev los ntawm cov kua dej txuas (lub npe dav dav rau cov kav roj thiab cov pob qij txha) lossis hydraulic manifolds. tsim ib lub voj voog. Kab lus no qhia txog kev teeb tsa thiab kev ceev faj rau cov kav dej hydraulic, hydraulic Cheebtsam, thiab cov khoom pabcuam hauv hydraulic systems.
Raws li daim ntawv txuas ntawm hydraulic tswj Cheebtsam, nws tuaj yeem muab faib ua: hom sib xyaw (hydraulic chaw nres tsheb hom); hom decentralized. Ob daim ntawv yuav tsum tau txuas nrog cov kua dej sib txuas.
1.Installation ntawm hydraulic Cheebtsam
Lub installation thiab cov kev cai tshwj xeeb ntawm ntau yam hydraulic Cheebtsam. Hydraulic Cheebtsam yuav tsum tau ntxuav nrog kerosene thaum lub sij hawm installation. Tag nrho cov hydraulic Cheebtsam yuav tsum tau mus rau lub siab thiab sealing kev xeem. Tom qab dhau qhov kev xeem, kev teeb tsa tuaj yeem pib. Ntau yam cuab yeej tswj tsis siv neeg yuav tsum tau ntsuas ua ntej kev teeb tsa kom tsis txhob muaj xwm txheej tshwm sim los ntawm qhov tsis raug.
Lub installation ntawm hydraulic Cheebtsam feem ntau yog hais txog lub installation ntawm hydraulic li qub, hydraulic kheej kheej, hydraulic twj tso kua mis thiab auxiliary Cheebtsam.
2. Kev txhim kho thiab kev xav tau ntawm hydraulic li qub
Ua ntej txhim kho hydraulic Cheebtsam, cov khoom siv hydraulic tsis tau ntim khoom yuav tsum xub xyuas daim ntawv pov thawj ntawm kev ua raws thiab tshuaj xyuas cov lus qhia. Yog tias nws yog cov khoom tsim nyog nrog cov txheej txheem ua tiav, thiab nws tsis yog cov khoom uas tau khaws cia rau hauv qhov chaw qhib rau lub sijhawm ntev thiab tau corroded nyob rau hauv, tsis tas yuav tsum tau kuaj ntxiv thiab tsis pom zoo. Nws tuaj yeem disassembled thiab sib dhos ncaj qha tom qab ntxuav.
Yog tias muaj kev ua haujlwm tsis zoo tshwm sim thaum lub sijhawm ua haujlwm, cov khoom siv yuav tsum tau disassembled thiab rov ua dua thaum qhov kev txiav txim yog qhov tseeb thiab tsim nyog. Tshwj xeeb tshaj yog rau cov khoom txawv teb chaws, random disassembly thiab sib dhos tsis tso cai kom tsis txhob cuam tshuam qhov tseeb ntawm cov khoom thaum nws tawm hauv lub Hoobkas.
Ua tib zoo saib cov hauv qab no thaum txhim kho hydraulic li qub:
1) Thaum txhim kho, xyuam xim rau txoj hauj lwm ntawm cov roj inlet thiab rov qab qhov chaw nres nkoj ntawm txhua lub valve.
2) Yog tias qhov chaw teeb tsa tsis tau teev tseg, nws yuav tsum tau muab tso rau hauv qhov chaw uas yooj yim rau kev siv thiab tu. Feem ntau, cov kev taw qhia tswj valve yuav tsum tau nruab nrog lub axis kab rov tav. Thaum txhim kho lub reversing valve, plaub screws yuav tsum tau nruj tusyees, feem ntau nyob rau hauv pawg ntawm kab pheeb ces kaum thiab maj mam nruj.
3) Rau li qub ntsia nrog flanges, cov ntsia hlau tsis tuaj yeem nruj dua. Kev nruj dhau tej zaum yuav ua rau tsis zoo sealing. Yog tias lub foob qub lossis cov khoom tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, daim ntawv lossis cov khoom ntawm lub foob yuav tsum tau hloov.
4) Rau qhov yooj yim ntawm kev tsim khoom thiab kev teeb tsa, qee qhov li qub feem ntau muaj ob lub qhov nrog tib txoj haujlwm, thiab qhov tsis siv yuav tsum tau thaiv tom qab kev teeb tsa.
5) Valves uas yuav tsum tau hloov kho feem ntau tig clockwise kom nce ntws thiab siab; tig counterclockwise kom txo qhov ntws los yog siab.
6) Thaum lub sijhawm teeb tsa, yog tias qee qhov valve thiab cov khoom sib txuas tsis muaj, nws raug tso cai siv hydraulic li qub nrog tus nqi txaus siab tshaj 40% ntawm lawv cov rated flow.
3. Kev teeb tsa thiab kev xav tau ntawm hydraulic lub tog raj kheej
Lub installation ntawm hydraulic lub tog raj kheej yuav tsum txhim khu kev qha. Yuav tsum tsis txhob muaj slack nyob rau hauv cov kav dej sib txuas, thiab lub mounting nto ntawm lub tog raj kheej thiab zawv zawg nto ntawm lub piston yuav tsum muaj txaus parallelism thiab perpendicularity.
Ua tib zoo saib cov hauv qab no thaum txhim kho lub tog raj kheej hydraulic:
1) Rau lub tog raj kheej txawb nrog lub hauv paus ruaj khov, nws lub hauv paus axis yuav tsum yog concentric nrog lub axis ntawm load quab yuam kom tsis txhob ua rau sab nraud quab yuam, uas tuaj yeem yooj yim ua rau lub foob hnav thiab piston puas. Thaum txhim kho lub tog raj kheej hydraulic ntawm ib qho khoom txav, ua kom lub tog raj kheej tig mus rau qhov kev taw qhia ntawm kev txav ntawm cov khoom txav ntawm qhov taw qhia rail nto.
2) Txhim kho lub sealing gland ntsia hlau ntawm hydraulic lub tog raj kheej thaiv thiab ceev nws kom ntseeg tau tias lub piston txav thiab ntab thaum lub sij hawm tag nrho cov hlab ntsha los tiv thaiv kev cuam tshuam ntawm thermal expansion.
4. Kev teeb tsa thiab kev xav tau ntawm hydraulic twj tso kua mis
Thaum lub twj tso kua mis hydraulic tau teem rau ntawm lub tank cais, muaj ob txoj kev teeb tsa: kab rov tav thiab ntsug. Vertical installation, cov kav dej thiab cov twj tso kua mis yog nyob rau hauv lub tank, ua rau nws yooj yim los sau cov roj to thiab cov tsos zoo nkauj. Kab rov tav installation, cov kav dej raug tawm sab nraud, ua rau kev teeb tsa thiab kev saib xyuas yooj yim dua.
Hydraulic twj feem ntau tsis tso cai rau dais radial loads, yog li hluav taws xob motors feem ntau siv los tsav ncaj qha los ntawm elastic couplings. Thaum lub sij hawm installation, nws yuav tsum tau hais tias lub shafts ntawm lub cev muaj zog thiab hydraulic twj tso kua mis yuav tsum muaj siab concentricity, lawv deviation yuav tsum tsawg tshaj li 0.1 hli, thiab lub inclination lub kaum sab xis yuav tsum tsis txhob ntau tshaj 1 ° kom tsis txhob ntxiv load rau lub twj tso kua mis ncej. thiab ua suab nrov.
Thaum siv los yog iav kis tau tus mob yog tsim nyog, lub twj tso kua mis hydraulic yuav tsum tau tso cai tshem tawm radial thiab axial loads. Hydraulic motors zoo ib yam li cov twj tso kua mis. Qee lub cev muaj zog tau tso cai rau dais ib qho radial lossis axial load, tab sis nws yuav tsum tsis txhob tshaj qhov tau teev tseg. Qee lub twj tso cai rau qhov siab dua qhov nqus dej. Qee lub twj tso kua mis taw qhia tias qhov chaw nres nkoj roj yuav tsum qis dua cov roj theem, thiab qee lub twj tso kua mis tsis muaj peev xwm ua rau nws tus kheej xav tau lub twj tso kua mis ntxiv los muab cov roj.
Ua tib zoo saib cov hauv qab no thaum txhim kho lub twj hydraulic:
1) Lub inlet, qhov hluav taws xob thiab kev sib hloov kev taw qhia ntawm lub twj tso kua mis hydraulic yuav tsum ua raws li qhov yuav tsum tau cim rau ntawm lub twj tso kua mis, thiab yuav tsum tsis txhob txuas rov qab.
2) Thaum txhim kho lub coupling, tsis txhob ntaus lub twj tso kua mis lub zog kom tsis txhob ua rau lub twj tso kua mis rotor.
5. Kev teeb tsa thiab kev xav tau ntawm cov khoom pabcuam
Ntxiv nrog rau kev sib txuas ntawm cov kua dej, cov khoom sib koom ua ke ntawm lub tshuab hydraulic kuj suav nrog cov lim dej, cov khoom siv, cov khoom siv txias thiab cov cua sov, cov khoom siv sib khi, cov ntsuas ntsuas siab, ntsuas ntsuas qhov ntsuas, thiab lwm yam. Thaum lub sij hawm installation, txwv tsis pub lawv yuav cuam tshuam rau kev ua haujlwm ntawm hydraulic system.
Ua tib zoo mloog cov hauv qab no thaum txhim kho cov khoom pab cuam:
1) Kev teeb tsa yuav tsum tau ua kom nruj raws li cov qauv tsim thiab kev saib xyuas yuav tsum tau them rau kev zoo nkauj thiab kev zoo nkauj.
2) Siv roj av los ntxuav thiab tshuaj xyuas ua ntej kev teeb tsa.
3) Thaum ua tau raws li cov qauv tsim, xav txog kev yooj yim ntawm kev siv thiab tu kom ntau li ntau tau.
