Nyob rau hauv lub ncu turbine Electro-hydraulic tswj system, tusSERVO VALVEG771K201 plays ib qho tseem ceeb heev tshaj plaws, thiab nws cov kev ua tau ncaj qha cuam tshuam nrog kev tswj hwm raug thiab ruaj khov ntawm tag nrho cov kab ke. Txawm li cas los xij, lub xoom bias drif dab yog zoo li lub peev xwm "dab yog qhov ua tau zoo ntawm cov khoom siv hluav taws xob hluav taws xob Electro-hydraulic tswj hwm. Yog li ntawd, nws yog qhov zoo ntawm kev ua tau zoo kom muaj kev nkag siab tob txog ntawm lub xoom bias qhov tshwm sim ntawm lub Vero Daws Phenomenon ntawm cov qauv zoo thiab ntsuas hluav taws xob.

1. Kev Ntsuam Xyuas Ntawm Xoom Bias Drift phenomenon ntawm servo Valve G771K201

Lub xoom indero ntawm servo valve g771k201, nyob rau hauv cov lus yooj yooj yim, hais txog qhov teeb meem uas cov zis ntws tawm thaum muaj tsawg kawg thaum tsis muaj teeb meem tswj cov ntsiab lus. Lub Xoom Bias Drift tshaj tawm kev hloov pauv ntawm lub caij nyoog tsis raug cai nrog kev hloov pauv ntawm lub sijhawm, ntsuas kub thiab lwm yam.

Muaj ntau ntau yam uas ua rau xoom Bias drift. Los ntawm sab hauv cov ntsiab lus, hnav ntawm sab hauv cov feem ntawm servo valve yog ib qho laj thawj tseem ceeb. Piv txwv li, tom qab siv ntev, qhov txuam nrog tshem tawm ntawm lub tshav valve tej zaum yuav hloov pauv, ua rau muaj kev hloov pauv ntawm cov kua dej xau, uas nyob rau hauv qhov ua rau xoom bias drift. Tsis tas li ntawd, elastic lim tawm ntawm lub caij nplooj ntoo hlav tsis tuaj yeem tsis quav ntsej. Thaum lub sij hawm ntev kev nthuav dav thiab cov txheej txheem txhawb nqa, tus txheej txheem elastic coefficient ntawm lub caij nplooj ntoos hlav yuav hloov, cuam tshuam rau qhov pib ntawm lub valve bias drift. Los ntawm qhov kev pom ntawm sab nraud yam, qhov kev hloov kom kub muaj qhov cuam tshuam tseem ceeb ntawm xoom tsis ncaj qha drift. Kev hloov pauv kub yuav ua rau sib txawv thermal nthuav cov coefficients ntawm cov ntu ntawm cov khoom kom hloov, yog ua rau xoom kev tsis muaj kev cuam tshuam. Ib qho ntxiv, qhov tsis txaus ntseeg ntawm lub cev lub zog kuj tseem tuaj yeem ua rau xoom bias drift. Kev hloov kho ntawm qhov siab yuav tsim cov zog ntxiv rau ntawm lub valve core, ua rau nws tau cuam tshuam los ntawm thawj qhov chaw xoom.

2. Nrhiav kom pom txoj kev ntawm xoom Bias Drift ntawm Servo Valve G771K1

(I) Txoj kev kuaj pom zoo li qub

Cov qauv kev kuaj pom zoo li qub yog qhov yooj yim thiab siv tau siv cov qauv kuaj pom. Thaum lub system nyob hauv lub xeev zoo li qub, kev paub txog cov khoom siv high-precisionSiab SensorsThiab cov flowors, yog siv los ntsuas cov zis siab thiab ntws ntawm servo valve thaum tsis muaj kev tswj cov paib. Ua ntej, rov qab txuas lub servo valve mus rau kev kuaj pom kom ntseeg tau tias cov kab ke nyob hauv lub xeev ruaj khov. Tom qab ntawd, sau lub siab thiab ntws cov ntaub ntawv ntsuas los ntawm sensor nyob rau lub sijhawm no, uas yog qhov tseem ceeb ntawm lub zero kev tsis ncaj ncees. Raws li kev sib txawv ib puag ncig, xws li ntau kub thiab av noo, ntsuas ntau zaus thiab sib piv cov ntaub ntawv ntsuas. Yog hais tias muaj kev pom tseeb nyob rau hauv cov ntaub ntawv, thiab kev hloov kho qhov yuam kev uas tau txiav txim siab tias servo valve muaj xoom bias drift.

(II) Dynamic Kev Kho Mob

Txoj kev siv zog siv tau tuaj yeem cuam tshuam ntau dua tiag tiag txog lub xoom indero drift ntawm servo valve thaum lub sijhawm ua haujlwm tiag tiag. Thaum lub sijhawm ua haujlwm ntawm lub kaw lus, cov teeb tsa kev tswj hwm, tso tawm kev txaus ntawm servo valve tau sau nyob rau hauv lub sij hawm tiag tiag siv cov ntaub ntawv nrhiav tau. Los ntawm kev txheeb xyuas cov ntaub ntawv siv cov dynamic, saib seb cov zis txaus thiab siab ua haujlwm hloov kho thaum lub teeb liab tswj yog xoom. Cov txheej txheem kev teeb liab xws li kev tsom xam pom kev puas tuaj yeem siv los soj ntsuam cov zaus thiab qhov nrawm ntawm kev hloov pauv. Yog tias cov conventje ampitude yog qhov loj thiab zaus qhia tau qee yam tsis tu ncua lossis tsis xwm yeem, tom qab ntawd nws qhia tau tias lub servo valve yuav muaj xoom kev ntxub ntxaug. Piv txwv li, tom qab lub kaw lus tau khiav stably rau ib lub sijhawm, nws pom tias cov zis ntws tau muaj qee ntu me me thaum tswj cov teeb liab yog xoom. Tom qab tshuaj xyuas thiab tsis suav rau lwm yam cuam tshuam rau qhov cuam tshuam, nws zoo li yog tias lub bias ntawm lub servo valve tau drifted.

(Iii) qauv raws li kev kuaj mob

Nrog rau kev txhim kho kev tswj hwm niaj hnub thiab Computer Technology, qauv kev kuaj kom paub txoj hau kev tau siv maj. Ua ntej, tsim kom muaj qhov qauv lej ntawm servo Valve G771K201, uas yuav tsum muaj peev xwm piav qhia qhov kev tawm tswv yim thiab cov zis ntawm servo valve nyob rau hauv cov kev ua haujlwm sib txawv. Tom qab ntawd, piv qhov sau tau sau cov servo valve thiab cov zis cov ntaub ntawv nrog cov qauv kwv yees tus nqi. Yog tias qhov kev sib txawv ntawm ob qhov ntau tshaj qhov teeb tsa qhov teeb tsa, nws txhais tau tias lub servo valve yuav muaj xoom dab tsi drift. Piv txwv li, siv cov qauv network network los ua qauv ntawm cov qauv ntawm cov qauv ntawm kev twv ua ntej los ntawm kev sib piv ntawm tus nqi kwv yees thiab tus nqi tiag tiag. Cov qauv no muaj qhov muaj tseeb thiab kev txawj ntse, tab sis yuav tsum muaj ntau cov ntaub ntawv sim los qhia cov qauv los ua kom ntseeg tau ntawm tus qauv.

3. Kev ntsuas hluav taws xob rau xoom Bias Drift ntawm Servo Valve G771K201

(I) kev kho tshuab kev hloov kho calibration

Mechanical hloov kho calibration yog ib hom kev ntsuas hluav taws xob ntau. Rau xoom Bias drift tshwm sim los ntawm lwm cov neeg kho tshuab xws li kev ua haujlwm valve ua haujlwm offset, calibration tuaj yeem ua los ntawm kev kho qhov pib ntawm lub valve core. Ua ntej, qhib lub plhaub sab nraud ntawm servo valve thiab nrhiav lub valve core kev hloov kho tshuab. Tom qab ntawd, siv cov cuab yeej tshaj lij, xws li precision cov ntsia hlau, kom kho qhov chaw ntawm lub valve core hauv cov kev taw qhia thiab amplitude. Thaum lub sij hawm hloov kho, ua ke cov qauv kev kho kom raug los ntsuas lub xoom uas muaj nuj nqis ntawm lub sijhawm servo valve nyob rau hauv lub sij hawm tiag tiag mus txog rau cov muaj ntau yam. Tom qab kev hloov kho tau ua tiav, xyuas kom lub valve kev hloov kho tshuab yog khov kho kom tiv thaiv kev tsis txaus siab thaum ua haujlwm.

(II) Kev Kho Mob Hluav Taws Xob calibration

Kev them nyiaj hluav taws xob calibration siv hluav taws xob cov teeb tsa los them rau cov cawv ntawm xoom kev ntxub ntxaug. Los ntawm kev them nyiaj rau kev them nqi hluav taws xob lossis software algorithm rau cov kev tswj hwm, cov zis tawm ntawm lub teeb liab ntawm servo valve yog kho nyob rau hauv lub sijhawm tiag tiag. Piv txwv li, hais txog cov khoom siv kho vajtse, kev them nyiaj raws li lub cim tswj kev ua haujlwm tau ua tiav raws li lub cim tswj kev ua haujlwm tau raws li lub cim tswj kev ua haujlwm tau raws li lub cim kev tswj hwm tus nqi, uas yog superset ntawm lub cim kev tswj hwm tus nqi, uas yog superset ntawm cov cim kev tswj hwm tus nqi, uas yog cov supero valve kom tau offection tus cawv ntawm xoom tsis ncaj ncees. Nyob rau hauv cov nqe lus ntawm software, pid tswj algorithms tuaj yeem siv los kho cov nyiaj them nqi raws li cov ntaub ntawv bis cov ntaub ntawv los ua kom cov zis ntawm lubSERVO VALVEruaj khov.

(III) Hloov ntawm cov khoom tseem ceeb rau kev ntsuas

Yog tias nws tau pom los ntawm kev tshuaj ntsuam xyuas tias lub voos xwm txheej xoom yog tshwm sim los ntawm kev puas tsuaj lossis kev hloov pauv ntawm cov txheej txheem no yog ib hom kev ntsuas hluav taws xob zoo. Piv txwv li, yog tias lub caij nplooj ntoo hlav muaj kev qaug zog elastic, ua rau xoom bias drift, tom qab ntawd lub caij nplooj ntoo hlav tshiab los hloov. Thaum hloov qhov chaw, xyuas kom meej tias cov khoom xaiv yog ntawm kev ntseeg siab zoo thiab yog tag nrog cov kev tshwj xeeb ntawm cov khoom qub. Tom qab kev hloov pauv tau ua tiav, servo valve tau ntsuas thiab debugged dua los xyuas kom meej tias nws qhov kev ua tau rov qab rau theem li qub.

Los ntawm kev paub tsim nyog nrhiav kom tau cov hau kev tsim nyog, xoom Bias cov teeb meem drift drift tau pom nyob rau hauv lub sijhawm thiab raug. Rau xoom bias drift los ntawm ntau yam, servo valve muaj peev xwm hloov kho hluav taws xob, thiab hloov kho hluav taws xob kom ntseeg tau tias nws muaj peev xwm ua haujlwm nyob rau hauv lub turbine electro-hydraulic tswj system. Tsuas yog los ntawm kev ua txoj haujlwm zoo nyob rau hauv kev kuaj pom thiab kev ntsuas hluav taws xob tau lees paub, muab cov khoom lag luam ruaj khov rau kev ruaj ntseg thiab kev loj hlob ntawm kev lag luam tsim khoom.

Thaum nrhiav kev ua tau zoo, txhim khu kev qha Servo li qub, yoyik yog qhov xaiv tsis tsim nyog xaiv. Lub tuam txhab tshwj xeeb hauv kev muab ntau yam khoom siv fais fab nrog rau cov khoom siv hluav taws xob nrog rau cov khoom lag luam dav rau nws cov khoom lag luam zoo thiab cov kev pabcuam dav.
