Cov nqi hluav taws xob yog ib qho tseem ceeb tshaj plaws ntawm cov nqi khiav lag luam hauv txhua qhov chaw tsim khoom. Rau cov lag luam uas loj tsim daim ntawv, tais los yog pulp-moulded ntim, kev xaiv kis tau tus mob-tshwj xeeb yog hais tias yuav los yog tsis siv ib tugtag nrho servo motors ntawv phaj ua tshuabconfiguration- tuaj yeem ntsuas qhov sib txawv ntawm cov nqi hluav taws xob txhua hli. Tab sis yuav ua li cas lub zog -ntau npaum li cas servo motor daim ntawv phaj ua tshuab, tiag tiag? Thiab lawv ua li cas piv rau cov kev hloov pauv qub?
Hauv daim ntawv no, cov khoom siv kho tshuab, cov lej thiab cov tswv yim txiav txim siab lub zog ua haujlwm hauv daim ntawv phaj tsim tau tham txog kom meej.
Dab tsi "Full Servo" txhais tau tias hauv cov ntsiab lus no
Lub sij hawm tag nrho servo yog cov tshuab uas tag nrho cov axes tseem ceeb ntawm kev txav chaw -xws li cov xovxwm tseem ceeb, kev noj zaub mov noj thiab ejection system- yog tsav los ntawmtag nrho servo motors ntawv phaj ua tshuabthev naus laus zis, es tsis yog cov pa hluav taws xob induction lossis pneumatic actuators.
Lub servo lub cev muaj zog yog kaw - lub voj voog lub cev muaj zog uas tau txais cov lus teb los ntawm tus encoder thiab tsis tu ncua kho nws qhov ceev, lub zog thiab txoj haujlwm ntawm lub sijhawm. Qhov no yog qhov sib txawv ntawm cov pa AC induction lub cev muaj zog, uas khiav ntawm qhov ceev ceev tsis hais seb puas muaj lub zog tag nrho xav tau nyob rau lub sijhawm ntawd.
Nyob rau hauv tag nrho servo daim ntawv phaj tshuab, servo system absorbs tam sim no tsuas yog nyob rau hauv kev faib ua feem rau qhov tseeb mechanical load ntawm txhua theem ntawm lub voj voog. Thaum lub sij hawm nyob hauv theem - thaum pwm tuav txoj hauj lwm - lub cev muaj zog yuav luag tsis muaj dab tsi. Thaum lub sij hawm nias, nws ramps. Qhov no dynamic load- txuam yog lub hauv paus ntawm servo zog efficiency.
Lub zog sib piv: Servo vs. Pas Drive Systems
Txhawm rau kom nkag siab qhov sib txawv ntawm qhov ua tau zoo, saib cov khib nyiab ntawm cov tshuab tsoos.
Cov ntawv phaj ib txwm raug teeb tsa nrog cov tsav tsheb hauv qab no:
AC induction lub cev muaj zog + flywheel + clutch / nres: Lub cev muaj zog khiav tsis tu ncua ntawm qhov nrawm thiab lub flywheel khaws lub zog kinetic. Lub clutch koom rau tsav lub xovxwm stroke. Lub zog yog siv tas li txawm tias tsis muaj qhov tshwm sim.
Hydraulic zog chav tsev: Lub twj tso kua mis hydraulic tsav los ntawm induction lub cev muaj zog uas khiav tsis tu ncua los tswj lub zog siab. Yog hais tias cov xovxwm nyob twj ywm los yog tos ntawm lub voj voog, lub twj tso kua mis tseem siv roj thiab siv zog.
Pneumatic systems: Lub tshuab cua compressor yuav luag ua haujlwm tas mus li, vim kev poob qis thiab cov pa tawm, kev ua haujlwm ntawm cov tshuab pneumatic twb tsawg heev.
Hauv peb qhov xwm txheej, kev siv hluav taws xob feem ntau yog decoupled los ntawm qhov xav tau tiag tiag. Lub tshuab txav ze rau - lub zog tag nrho txawm hais tias nws nyob nruab nrab - mob stroke lossis tos rau qhov khoob tom ntej kom noj.
Tag nrho servo systems tshem tawm cov khib nyiab no. Cov ntaub ntawv kev lag luam thiab cov cuab yeej ntsuas ntsuas tsis tu ncua qhia tau hais tias tag nrho servo daim ntawv phaj tshuab siv 30% mus rau 60% hluav taws xob tsawg dua piv rau qhov sib npaug hydraulic lossis flywheel- cov tshuab tshuab ua cov khoom ntim tib yam.
Qhov tseeb, qhov nruab nrab - loj daim ntawv phaj ntau lawm kab khiav ob zaug ib hnub twg yuav txuag tau ntawm 8,000 thiab 25,000 kilowatt-teev ib xyoos los ntawm kev hloov ntawm hydraulic mus rau tag nrho servo tsav, nyob ntawm seb lub tshuab loj, qhov ceev ntawm kev tsim khoom thiab cov nqi hluav taws xob hauv zos.
Vim Li Cas Cov Nyiaj Txiaj Ntsig thiaj li sib xws
Ntau yam engineering ntxiv los piav qhia vim li cas tag nrho cov tshuab servo ua tau zoo heev ntawm lub zog:
Regenerative Braking
Thaum servo lub cev muaj zog decelerates down - zoo li thaum kawg ntawm ib tug mob stroke ua ntej reversing - nws ua zoo li lub tshuab hluav taws xob, retrieving kinetic zog thiab pub nws rov qab mus rau tus tsav tsheb npav los yog capacitor bank. Qhov norov tsim dua tshiabmuaj peev xwm txhais tau hais tias lub zog yog recaptured dua li dissipated li cua sov, raws li nws yuav nyob rau hauv ib tug neeg kho tshuab nres los yog hydraulic nyem valve.
Cov kev kho me me no ntxiv rau ib feem tseem ceeb ntawm tag nrho cov peev nyiaj siv hluav taws xob rau kev caij tsheb kauj vab nrawm uas khiav ntawm 60 thiab 120 neeg ntaus ib feeb.
Precise Motion Profiles
Servo controllers tso cai rau cov engineers los tsim cov kev cai txav profile rau txhua tus ncej. Hloov lub cam ruaj khov-tsav stroke, cov xovxwm tuaj yeem ua kom nrawm nrawm, qeeb ua ntej kaw kom txo qhov cuam tshuam, nyob ntawm qhov zoo siab, tom qab ntawd thim rov qab sai sai - tag nrho hauv txoj kab ncaj nraim, ua kom zoo dua qub. Qhov no txo qhov siab tshaj tam sim no kos thiab txhua yam kev ntxhov siab ib txhij.
Tshem tawm ntawm Standby Losses
Hydraulic systems xav tau lub twj tso kua mis tsis tu ncua kom tswj lub zog siab. Txawm nyob hauv qhov tsis muaj zog, qhov no raug nqi zog. Lub servo tsav ntawm standby kos ze rau - xoom tam sim no. Rau kev khiav hauj lwm uas nquag nres, hloov pauv, lossis hloov pauv - lub sijhawm xav tau, qhov sib txawv no sib xyaw ua ke ntau dhau ib xyoos.
Txo cov cua sov tsim
Vim tias cov servo motors ua haujlwm tau zoo dua, lawv tsim hluav taws xob tsawg dua. Qhov no muaj qhov txiaj ntsig thib ob: txo cov cua txias rau lub txee hluav taws xob thiab qhov chaw ua haujlwm ib puag ncig, uas txhais tau tias txo qis HVAC loads hauv qhov chaw tsim khoom.
Kev ua tau zoo tiag tiag vs. Rated Efficiency: Dab tsi los saib
Cov neeg tsim khoom siv lub zog siv specs feem ntau ntsuas nyob rau hauv cov xwm txheej zoo meej. Qhov ntawd txhais tau tias khiav txhua lub sijhawm tsis muaj kev nres. Tab sis tiag tiag -kev ua tau zoo hauv ntiaj teb nyob ntawm ob peb yam ntxiv.
Ua ntej yog ntau lawm ceev. Lub zog siv ib yam khoom yog qhov zoo tshaj plaws thaum lub tshuab khiav ntawm lossis ze rau nws qhov ntsuas ceev. Yog tias koj khiav ntawm 50% ntawm lub tshuab ua rau cov zis siab, nws yuav siv zog tsawg dua. Tab sis nws yuav ua rau lub zog -ib - phaj piv tsis zoo.
Qhov thib ob yog cov yam ntxwv ntawm cov khoom. Thicker lossis denser raw cov ntaub ntawv xav tau ntau txoj kev quab yuam. Qhov no ua rau kom lub cev muaj zog torque xav tau. Yog tias koj hloov los ntawm cov ntawv txheem rau hnyav dua lossis ntau- txheej ntawv, lub zog siv ib lub voj voog yuav nce mus.
Qhov thib peb yog kev kho qhov kub thiab txias. Cov cua kub hauv qhov tuag tsis cuam tshuam rau kev siv lub zog ntawm servo tsav system.
Kev rwb thaiv tsev zoo ntawm cov pwm sib dhos thiab ua kom zoo cua sov- nce / txias- cov voj voog qis tseem ceeb npaum li lub zog tsav rau tag nrho lub zog ua haujlwm.
Kev tu raws li txoj cai: hnav bearings, misaligned qhia rails, los yog kis kab mob servo tawm tswv yim encoders tsub kom kev sib txhuam thiab tsis kam, yuam lub cev muaj zog ua hauj lwm nyuaj. Ib qhov dej- khaws ciatag nrho servo motors ntawv phaj ua tshuabtsis tu ncua outperforms ib tug neglected ib tug ntawm lub zog metrics.
Tshaj Tawm Zog: Lwm cov txiaj ntsig ua haujlwm ntawm Full Servo
Zog efficiency yog lub ntsiab qhia. Tab sis tag nrho cov tshuab servo kuj muaj lwm cov ntsiab lus zoo rau kev ua haujlwm. Cov no yog tsim nyog xav txog:
Siab dua Precision thiab rov ua dua
Vim hais tias servo motors teb rau tiag - lub sij hawm encoder tawm tswv yim, qhov sib xws ntawm qhov ntev ntawm ntau txhiab lub voj voog yog qhov zoo dua li cam drives lossis hydraulic presses. Qhov no txo cov nqi seem - uas yog nws tus kheej ib daim ntawv ntawm cov khoom thiab lub zog efficiency.
Tsawg suab nrov
Hydraulic hwj chim units thiab pneumatic systems yog notoriously nrov. Tag nrho cov tshuab servo ua haujlwm tau zoo dua, txhim kho qhov chaw ua haujlwm thiab txo qhov xav tau kev tiv thaiv kev hnov lus hauv cov chaw nrog cov kev cai nruj nruj.
Txo Lub Sijhawm Saib Xyuas Lub Sijhawm
Koj tsis tas yuav hloov cov roj hydraulic. Koj tsis tas yuav hloov cov lim dej. Koj tsis tas yuav ua raws li lub sijhawm kho cua compressor. Lub servo-tsav system muaj cov khoom siv tshuab yooj yim. Qhov no txhais tau hais tias tsawg dua kev npaj tu ncua. Nws kuj txhais tau tias muaj feem tsawg dua ntawm kev tawg tam sim ntawd. Nyob rau lub neej ntawm lub tshuab, qhov no ua rau cov khoom siv zoo dua qub (OEE). Yog li qhov no yog lwm txoj hauv kev kom tau txais txiaj ntsig tsis ncaj.
Cov ntaub ntawv thiab saib xyuas muaj peev xwm
Niaj hnub no servo drives muaj kev sib txuas lus interfaces. Cov no feem ntau yog Ethernet / IP, Ethernet Square, lossis Modbus. Lawv saib kev siv hluav taws xob, lub sijhawm voj voog, thiab lub cev muaj zog hauv lub sijhawm. Cov ntaub ntawv no tso cai rau cov neeg ua haujlwm tsim khoom pom qhov tsis muaj txiaj ntsig. Nws kuj tseem cia lawv taug qab siv lub zog rau txhua qhov kev tsim khoom. Thiab nws cia lawv npaj cov sijhawm siv tawm - cov nqi hluav taws xob siab tshaj.
Puas yog Tus Nqi Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Tawm?
Tag nrho servo daim ntawv phaj tshuab feem ntau muaj tus nqi yuav ntau dua li lawv cov hydraulic lossis cov khoom sib npaug ntawm tib lub ntim. Tus nqi sib txawv los ntawm kev ua lag luam thiab kev teeb tsa, tab sis 20% mus rau 40% tus nqi peev ntau dua tsis txawv. Kev nqis peev hauv ibtag nrho servo motors ntawv phaj ua tshuabyuav tsum tau ua tib zoo soj ntsuam ntawm cov ntim ntau lawm thiab nqi zog.
Rau feem ntau nruab nrab-thiab loj- cov lag luam muaj peev xwm, lub sijhawm them rov qab rau kev txuag hluav taws xob ib leeg yog nyob rau hauv 2 mus rau 4 xyoo ntawm tus nqi hluav taws xob ib txwm muaj- thiab nyiam luv dua hauv cov cheeb tsam uas muaj cov nqi lag luam siab. Thaum txo tus nqi txij nkawm thiab txo cov nqi seem raug suav nrog, tag nrho cov nqi ntawm cov tswv cuab daim duab ua qhov tseem ceeb dua.
Rau qhov tsawg- ntim lossis ib puag ncig kev tsim khoom sib cuam tshuam, lub laij lej txawv. Yog tias lub tshuab ua haujlwm tsuas yog ob peb teev hauv ib hnub, qhov kev txuag hluav taws xob tsawg tsawg dua thiab lub sijhawm them rov qab txuas ntxiv raws li.
Cov ntsiab lus
Daim ntawv servo lub cev muaj zog yog qhov muaj zog ntau dua li hydraulic, pneumatic, los yog flywheel -kev hloov kho tshuab - kev siv hluav taws xob ncaj qha feem ntau yog li ntawm 30% mus rau 60%. Kev ua tau zoo yog los ntawm kev thauj khoom- teb lub cev muaj zog tswj, rov ua kom lub zog rov qab, thiab tshem tawm cov kev poob qis hauv cov tshuab hydraulic.
Cov thev naus laus zis tseem muab cov txiaj ntsig sab nraud ntawm qhov raug, theem suab nrov, kev saib xyuas thiab cov ntaub ntawv pom, txhim kho kev lag luam tag nrho. Rau cov lag luam npaj ib txoj kab tshiab los yog hloov kho cov cuab yeej uas twb muaj lawm, lub zog ua haujlwm ntawm lub zog tsav tsim nyog rau qhov hnyav hauv kev txiav txim siab yuav khoom - tsis yog tus nqi ntawv nplaum xwb.
