Cov actuators feem ntau suav nrog hluav taws xob actuators, pneumatic actuators thiab hydraulic actuators:
1. Cov Hluav Taws Xob Hluav Taws Xob: Cov tshuab hluav taws xob tsuas yog siv hauv cov chaw tsim hluav taws xob los yog cov chaw tsim hluav taws xob nuclear vim tias kev du, ruaj khov thiab qeeb yog yuav tsum muaj nyob rau hauv cov dej siab. Qhov zoo tseem ceeb ntawm lub tshuab hluav taws xob yog qhov chaw siab thiab lub zog thawb uas tus neeg siv yuav thov tau. Qhov cuam tshuam los tiv thaiv kev muaj peev xwm ntawm lub tshuab hluav taws xob ua tau zoo heev, thiab lub zog lossis lub zog ntawm cov zis yog qhov pib tas mus li, uas tuaj yeem kov yeej qhov nruab nrab. Tshuav qhov sib npaug, tswj kev tswj cov txheej txheem tsis tiav, yog li kev tswj qhov tseeb yog siab dua pneumatic actuators. Yog hais tias servo amplifier siv, nws yog qhov yooj yim kom ua tiav kev hloov pauv ntawm qhov zoo thiab tsis zoo, thiab nws kuj yog yooj yim los teeb tsa qhov xwm txheej ntawm lub xeev-off-signal valve txoj hauj lwm (tuav / puv-qhib / puv-tawm), thiab thaum twg nws yog qhov yuam kev, nws yuav tsum nyob hauv qhov chaw, qhov no yog Pneumatic actuators tsis, pneumatic actuators yuav tsum muaj kev nyab xeeb los ntawm kev siv cov txheej txheem tiv thaiv kev tiv thaiv. Qhov luv ntawm cov hluav taws xob ua hluav taws xob yog: tus qauv nyuaj dua, nws yog qhov muaj feem ntau rau qhov ua tsis tiav, thiab vim tias nws cov nyom, cov kev cai lij choj rau cov neeg tu vaj tsev nyob ntawm lub siab yog siab dua; lub cev muaj zog ua kom muaj cua sov, yog tias kev kho kom haum nrawm dhau, nws yuav yooj yim ua rau lub zog dhau ntawm lub tshuab hluav taws xob, ua kom muaj kev tiv thaiv cua sov, thiab tseem ua rau hnav lub zog txo qis; Tsis tas li ntawd, nws khiav qeeb qeeb, thiab nws siv sijhawm ntev los tsim tawm lub teeb liab los ntawm tus kws tswj lub zog mus rau qhov chaw sib nug lus nyob rau hauv cov lus teb rau lub valve teb. Nws tsis zoo li pneumatic thiab hydraulic ua haujlwm.
2. Pneumatic Actuator: Feem ntau cov actuators siv nyob rau hauv kev tswj kev lag luam niaj hnub no yog pneumatic actuators. Vim tias lub zog ntawm cov pa hauv paus, nws muaj kev lag luam thiab kev lag luam piv rau hluav taws xob thiab hydraulic, thiab cov qauv yog yooj yim thiab tsis muaj peev xwm tuav tau thiab tswj tau. Txij ntawm kev saib xyuas, pneumatic actuator yog yooj yim dua rau kev khiav lag luam thiab ntsuas dua lwm yam kev ua raws, thiab nws tseem yog qhov yooj yim kom ua tiav kev sib raug zoo thiab tsis zoo hauv thaj teb. Nws qhov txiaj ntsig zoo tshaj yog kev nyab xeeb. Thaum siv qhov chaw qhia, nws yog qhov zoo rau qhov chaw kub ntxhov thiab tawg, thiab yog tias lub teeb liab hluav taws xob tsis tawg-pov thawj lossis muaj kev nyab xeeb, muaj qhov pheej hmoo ntawm hluav taws vim yog hluav taws. Yog li ntawd, kev thov ntau ntawm cov tswj kev siv hluav taws xob yog tam sim no dav thiab dav. Txawm li cas los xij, hauv kev lag luam chemical, pneumatic tswj qhov qub tseem nyob ntawm qhov kev lag luam muaj txiaj ntsig zoo. Cov kev cuam tshuam tseem ceeb ntawm cov pneumatic actuators yog: qeeb teb, tswj tsis tau qhov tseeb, thiab qhov tsis zoo tiv thaiv kev sib txawv, vim tias qhov hloov tau ntawm cov roj, tshwj xeeb tshaj yog thaum siv pneumatic loj loj, cua puv lub tog raj kheej thiab tua lub sijhawm. Tab sis qhov no yuav tsum tsis txhob muaj teeb meem, vim tias qhov theem siab ntawm kev tswj qhov tseeb thiab muaj peev xwm teb tau sai thiab tsis kam tiv thaiv kev sib txawv tsis tas yuav nyob hauv ntau cov kev ua haujlwm.
3. hydraulic actuator: Thaum xav tau qhov txawv txav los tiv thaiv kev ua tsis taus thiab lub siab thawb thiab tsim kom ceev nrawm, peb feem ntau xaiv txoj haujlwm hydraulic lossis electro-hydraulic. Vim tias qhov tsis yooj yim ntawm cov kua, qhov zoo ntawm kev siv hydraulic actuator yog lub zog tiv thaiv mus rau qhov tsis zoo, uas yog qhov tseem ceeb rau kev kho cov kev ua haujlwm, vim tias qhov tsis zoo no tsis ruaj khov thaum lub sijhawm hloov kho nyob ze rau lub rooj valve, ntau Lub siab txawv sib txawv, thiab qhov xwm txheej hnyav dua. Tsis tas li ntawd, txoj cai tswj hwm hydraulic ua haujlwm nrawm heev thiab teb sai sai, yog li kev tswj qhov siab tuaj yeem ua tiav. Lub tshuab hluav taws xob-hydraulic ua rau lub cev muaj zog, roj twj tso kua mis thiab roj electro-hydraulic servo valve. Nws tuaj yeem ua haujlwm los ntawm kev txuas lub zog muab hluav taws xob thiab tswj lub cim. Cov hydraulic actuator zoo ib yam li lub tog raj kheej, tab sis nws tuaj yeem tiv taus lub siab siab dua lub tog raj kheej. Kev ua haujlwm xav tau lub kaw lus hydraulic sab nraud, thiab cov nroj tsuag yuav tsum tau nruab nrog lub chaw nres tsheb hydraulic thiab cov kab xa. Hauv kev sib piv, tus xaim hluav taws xob-hydraulic tus qauv ua kom yooj yim dua.
Cov kev cuam tshuam tseem ceeb ntawm kev siv hydraulic ua yog qhov kev siv nyiaj ntau, qhov loj thiab lub cev tshuaj ntsuam lub cev, qhov tshwj xeeb tsis yooj yim thiab qhov xav tau ntawm kev ua haujlwm tshwj xeeb, yog li lawv feem ntau siv qee lub sijhawm tshwj xeeb xws li fais fab nroj tsuag thiab petrochemicals.
