Ib qho hydraulicproportional valve nrog amplifier cardyog ib qho tseem ceeb nyob rau hauv lub hydraulic system precisely tswj cov dej ntws thiab siab.Kab lus no yog xav paub ntau ntxiv txog qhov proportional valve amplifier yog dab tsi thiab nws ua haujlwm li cas nrog rau hydraulic proportional valve.
Hydraulic systems ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam suav nrog kev tsim khoom, tsheb thiab aerospace.Cov tshuab no siv hydraulic li qub los tswj cov dej ntws thiab kev taw qhia ntawm cov kua dej thiab thaum kawg ntawm kev txav ntawm cov khoom siv tshuab.Raws li qhov sib npaug yog tsim los muab qhov tseeb thiab du tswj cov kua dej ntws thiab siab.
Raws li lub npe implies, lub proportional valve amplifier amplifies lub teeb liab tswj tau txais los ntawm ib tug hais kom ua ntaus ntawv los yog sensor thiab txiav txim lub actuation ntawm proportional valve.Nws ua raws li tus choj ntawm lub teeb liab hais kom ua thiab cov proportional valve, kom ntseeg tau meej proportional tswj ntawm lub system.Daim npav amplifier yog lub rooj tsav xwm hluav taws xob hluav taws xob uas siv lub teeb liab tawm tswv yim thiab tsim cov teeb liab tawm suab kom tsav lub valve proportional.
Lub hauv paus ntsiab lus ua haujlwm ntawm hydraulicproportional valve nrog amplifier cardyog hloov qhov qhib qhov loj ntawm lub valve raws li lub teeb liab tswj hluav taws xob.Daim npav amplifier siv lub teeb liab hais kom ua (feem ntau nyob rau hauv daim ntawv ntawm qhov hluav taws xob lossis tam sim no) thiab hloov nws mus rau hauv lub teeb liab tam sim no uas tsav lub valve proportional.Lub teeb liab amplified no tswj cov spool txoj hauj lwm ntawm lub valve, uas nyob rau hauv lem tswj cov dej ntws.
Lub cev muaj zog valve ua kom muaj kev tswj xyuas meej los ntawm kev muab kev sib raug zoo ntawm cov teeb liab hais kom ua thiab lub valve tso tawm.Piv txwv li, 50% nce nyob rau hauv cov lus txib teeb liab ua rau 50% nce hauv cov dej ntws.Qhov kev tswj hwm qib no yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum muaj kev tswj hwm qhov sib npaug ntawm cov dej ntws los yog siab, xws li kev lag luam automation thiab kev tswj cov tshuab.
Raws li ib qho khoom siv hluav taws xob, daim npav amplifier kuj muaj ntau yam zoo dua li kev tswj hwm analog.Nws muaj kev txhim kho kev ntseeg siab, rov ua dua thiab hloov tau yooj yim hauv kev ua cov teeb liab.Niaj hnub nimno amplifier cards feem ntau muaj microprocessors rau kev ua haujlwm siab heev xws li teeb liab txias, kuaj mob, thiab kev sib txuas lus.
Kev sib xyaw ntawm hydraulic proportional li qub thiab amplifier phaib muab ntau yam txiaj ntsig rau hydraulic systems.Ua ntej, nws ua kom muaj kev tswj xyuas cov dej ntws thiab siab, txhim kho kev ua haujlwm thiab kev ua haujlwm zoo.Qhov thib ob, nws ua kom du, teb ua haujlwm nrog kev cuam tshuam tsawg thiab kev co.Thaum kawg, nws pab tswj cov chaw taws teeb tswj thiab automation, ua rau nws tsim nyog rau cov txheej txheem nyuaj lossis cov ntawv thov uas yuav tsum tau ua haujlwm nyob deb.
Hauv kev xaus, ib qho hydraulicproportional valve nrog amplifier cardyog ib qho tseem ceeb ntawm cov hydraulic system uas muab kev tswj xyuas cov dej ntws thiab siab.Proportional valve amplifiers ua lub luag haujlwm tseem ceeb hauv kev hloov cov lus txib rau hauv kev faib ua feem ntawm li qub.Nws muab kev tswj xyuas meej, kev ntseeg siab thiab kev ua haujlwm ntxiv los ntawm kev siv cov khoom siv hluav taws xob.Kev sib xyaw ua ke ntawm cov khoom no coj ntau qhov zoo rau hydraulic system, ua rau nws tsim nyog rau ntau yam kev siv thoob plaws ntau yam kev lag luam.
