Dab tsi txoj hauj lwm sensors siv nyob rau hauv hydraulic kheej kheej?
Nyob rau hauv niaj hnub no ceev ceev - hloov zuj zus muaj automation toj roob hauv pes, hloov sensors tsis yog ib tug pab Cheebtsam ntxiv lawm - lawv yog ib qho tseem ceeb rau yuav ua li cas hydraulic systems ua tau precision, efficiency, thiab kev ntseeg tau. Tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov hydraulic lub tog raj kheej, lub luag hauj lwm ntawm kev hloov pauv sensors tau dhau los ua qhov tseem ceeb. Yog tsis muaj qhov tseeb txoj haujlwm tawm tswv yim, txawm tias cov tshuab hydraulic siab tshaj plaws tsis tuaj yeem ua tau zoo ib yam.
Ntawm ntau yam technologies muaj, magnetostrictive displacement sensors sawv tawm raws li ib tug ntawm cov feem ntau txhim khu kev qha thiab dav saws daws. Lawv cov txiaj ntsig tseem ceeb - tsis yog - kev ntsuas kev sib cuag, qhov tso tawm qhov tseeb, qhov tseeb siab, thiab muaj zog ib puag ncig tiv thaiv- ua rau lawv tshwj xeeb tsim rau hydraulic lub tog raj kheej.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm magnetostrictive sensor yog raws li cov nyhuv magnetostrictive. Nyob rau hauv lub sensor, ib tug waveguide interacts nrog ib tug sib nqus teb generated los ntawm ib tug movable hlau nplaum txuas mus rau lub piston. Thaum cov magnetic teb sib cuam tshuam, cov neeg kho tshuab strain mem tes yog tsim thiab taug kev raws lub waveguide. Los ntawm kev ntsuas lub sij hawm nws yuav siv sij hawm qhov no mem tes rov qab, lub kaw lus xam qhov tseeb txoj hauj lwm ntawm lub piston.
Txoj kev no yog qhov sib txawv ntawm cov tshuaj sensors. Tsis txhob cia siab rau kev sib cuag ntawm lub cev lossis kev suav ntxiv, nws suav txoj haujlwm ncaj qha, uas ua rau muaj kev ntsuas ruaj khov thiab rov ua dua.
Hauv daim ntawv thov hydraulic lub tog raj kheej, lub hom phiaj ntawm kev siv lub tshuab hloov pauv yog qhov yooj yim: kev tswj xyuas kom meej meej. Txawm li cas los xij, qhov cuam tshuam ntawm qhov precision no tseem ceeb heev. Hauv ntau qhov kev lag luam, txawm tias qhov ua yuam kev me me tuaj yeem ua rau txo cov khoom zoo, nce hnav, lossis txawm tias lub cev tsis ua haujlwm.
Siv cov tshuab tsim ua piv txwv. Cov khoom siv xws li excavators thiab cranes vam khom rau hydraulic thooj voos kheej kheej rau kev txav mus los. Yog tias tsis muaj cov lus pom zoo ntawm txoj haujlwm, cov neeg ua haujlwm yuav tsum nyob ntawm kev paub ib leeg, uas txo qis kev ua haujlwm thiab ua rau muaj kev pheej hmoo ntawm kev nyab xeeb. Los ntawm kev sib koom ua ke magnetostrictive sensors, lub kaw lus tuaj yeem saib xyuas txoj haujlwm piston hauv lub sijhawm tiag tiag thiab hloov kho cov kev txav, ua rau kev ua haujlwm zoo dua thiab muaj kev nyab xeeb dua.
Lwm daim ntawv thov yog nyob rau hauv kev txhaj tshuaj molding tshuab. Cov tshuab no xav tau kev tswj xyuas qhov tseeb heev thaum lub sijhawm clamping thiab txhaj tshuaj. Ib qho kev sib txawv tuaj yeem ua rau cov khoom tsis raug lossis puas tsuaj rau pwm. Nrog magnetostrictive displacement sensors, manufacturers muaj peev xwm ua tau zoo ib yam, repeatable zog tswj, ho txhim kho cov khoom zoo.
Thaum nws los txog rau kev teeb tsa, kev hloov pauv hloov pauv rau lub tog raj kheej hydraulic feem ntau muab faib ua ob hom: sab hauv mounting thiab sab nraud mounting.
1.Internal mounting yog qhov kev daws teeb meem ntau dua. Lub sensor yog ntsia داخل hydraulic lub tog raj kheej, ua raws li tus pas nrig piston. Qhov kev tsim no muaj kev tiv thaiv zoo los ntawm ib puag ncig yam xws li plua plav, roj, thiab kev cuam tshuam txhua yam. Nws yog qhov zoo tagnrho rau kev ua haujlwm hnyav thiab kev tsim qauv tsim. Txawm li cas los xij, nws yuav tsum tau ua tib zoo saib xyuas thaum lub sij hawm tsim lub tog raj kheej, thiab kev saib xyuas yuav ua tau ntau dua.
2.External mounting, ntawm qhov tod tes, yog yooj yim rau nruab thiab tsim nyog rau retrofitting uas twb muaj lawm systems. Lub sensor yog mounted sab nraum lub tog raj kheej, feem ntau nyob rau hauv lub cev los yog nyob ze ntawm lub piston pas nrig. Thaum txoj kev no yooj yim rau kev teeb tsa thiab kev saib xyuas, nws raug cuam tshuam rau ib puag ncig kev puas tsuaj thiab xav tau kev tiv thaiv ntxiv.
Hauv kev xyaum, kev xaiv ntawm sab hauv thiab sab nraud mounting nyob ntawm daim ntawv thov scenario es tsis yog qhov twg yog "zoo dua." Nws yog kev txiav txim siab engineering raws li kev tsim qauv, qhov chaw muaj, thiab ib puag ncig.
Cia peb saib ntawm qhov tseeb - kis thoob ntiaj teb. Lub tuam txhab ua haujlwm steel ib zaug siv potentiometer-raws li sensors rau lawv lub tog raj kheej hydraulic nrog lub stroke ntev ntawm ib ncig ntawm 2 meters. Thaum xub thawj, qhov kev daws teeb meem yog tus nqi - zoo, tab sis dhau sijhawm, qhov tseeb degraded vim kev siv tshuab. Nquag recalibration thiab hloov pauv tau tsim nyog. Tom qab hloov mus rau magnetostrictive displacement sensors, lub kaw lus ua tiav ruaj khov, txij nkawm- ua haujlwm pub dawb rau ntau tshaj ob xyoos. Txawm hais tias thawj zaug peev tau siab dua, tag nrho cov nqi khiav lag luam poob qis heev.
Lwm qhov piv txwv yog los ntawm kev ua liaj ua teb machinery. Hauv cov qoob loo loj, cov tshuab hydraulic ua haujlwm hauv cov plua plav, ntub dej, thiab kev vibrational ib puag ncig. Cov tsoos sensors feem ntau ua tsis tau raws li cov xwm txheej zoo li no. Magnetostrictive sensors, nrog rau lawv cov kev tsim kho stainless hlau kaw (feem ntau nyob IP67 lossis IP68), tuaj yeem ua haujlwm ruaj khov nyob rau lub sijhawm ntev, txo qis sijhawm thiab nqi kho.
Thaum xaiv qhov hloov pauv hloov pauv rau lub tog raj kheej hydraulic, ntau yam tseem ceeb yuav tsum tau xav txog.
- Thawj yog qhov ntsuas qhov ntau. Qhov no yuav tsum phim lub cylinder stroke ntev, nrog rau qee qhov kev nyab xeeb kom tsis txhob ntsuas kev txwv thaum ua haujlwm.
- Qhov thib ob yog hom teeb liab tso zis. Nyob ntawm koj qhov kev tswj hwm, tej zaum koj yuav xav tau cov txiaj ntsig analog (xws li 4–20 mA lossis 0–10 V), cov txiaj ntsig digital (SSI), lossis cov txheej txheem kev sib txuas lus xws li CANopen lossis EtherCAT. Xaiv hom tso zis tsis raug tuaj yeem ua rau kev sib koom ua ke nyuaj.
- Qhov thib peb yog kev daws teeb meem thiab linearity. High- daim ntawv thov precision yuav tsum tau sensors nrog zoo daws teeb meem thiab zoo linearity nyob rau hauv tag nrho cov stroke.
Lwm qhov tseem ceeb yog kev tiv thaiv ib puag ncig. Hydraulic systems feem ntau ua haujlwm nyob rau hauv kev kub siab thiab hauv cov roj- puv ib puag ncig, yog li lub sensor yuav tsum muaj kev tiv thaiv tsim nyog thiab tsim kev sib khi.
Nrog rau kev txhim kho ntawm Kev Lag Luam 4.0, kev hloov pauv sensors kuj dhau los ua ntse dua. Niaj hnub nimno magnetostrictive sensors tuaj yeem suav nrog cov yam ntxwv xws li tus kheej- kuaj mob, ntsuas qhov kub thiab txias, thiab kev muaj peev xwm saib xyuas. Qee cov qauv txawm txhawb nqa cov ntaub ntawv kev koom ua ke nrog huab platforms, ua rau kev saib xyuas tej thaj chaw deb thiab kev ua kom zoo dua qub.
Los ntawm qhov kev xav dav dav, lub luag haujlwm ntawm kev hloov pauv sensors hauv hydraulic thooj voos kheej kheej tsis yog hais txog kev ntsuas - nws yog hais txog kev tswj hwm. Yog tsis muaj cov ntaub ntawv raug thiab txhim khu kev qha, cov tshuab automation siab heev tsis tuaj yeem ua haujlwm zoo.
Ntau lub tuam txhab nqis peev ntau hauv kev tswj hwm thiab software, tab sis yog tias cov ntaub ntawv hauv qab sensor tsis raug, tag nrho cov kab ke yuav tsis ruaj khov. Yog li ntawd, xaiv qhov kev hloov pauv zoo sensor tsis yog ib qho kev txiav txim siab nkaus xwb- nws yog ib qho kev tawm tswv yim uas cuam tshuam ncaj qha rau kev ua tau zoo, kev ntseeg siab, thiab ntev - nqi.
