A hydraulicvalavu yofananira yokhala ndi makadi amplifierndi gawo lofunikira mu dongosolo la hydraulic kuti lizitha kuyendetsa bwino madzimadzi komanso kuthamanga kwamadzi.Nkhaniyi ikufuna kudziwa zambiri za momwe ma valve amplifier ndi momwe amagwirira ntchito limodzi ndi hydraulic proportional valve.
Makina a Hydraulic amatenga gawo lofunikira m'mafakitale osiyanasiyana kuphatikiza kupanga, magalimoto ndi ndege.Machitidwewa amagwiritsa ntchito ma hydraulic valves kuti azitha kuyendetsa kayendedwe ka madzi ndi kayendedwe ka madzi ndipo potsirizira pake kuyenda kwa zigawo zamakina.Ma valve ofananira amapangidwa kuti aziwongolera molondola komanso mosasunthika pakuyenda kwamadzimadzi ndi kuthamanga.
Monga momwe dzinalo limatanthawuzira, proportional valve amplifier imakulitsa chizindikiro chowongolera chomwe chimalandilidwa kuchokera ku chipangizo cholamula kapena sensa ndikuzindikira kuyendetsa kwa valve yolingana.Imakhala ngati mlatho pakati pa chizindikiro cha lamulo ndi valavu yofananira, kuonetsetsa kuti dongosololi likuyendetsedwa bwino.Khadi la amplifier ndi bolodi lamagetsi lamagetsi lomwe limatenga chizindikiro cholowera ndikupanga chizindikiro chokulirapo kuti chiyendetse valavu yofananira.
Mfundo ntchito ya hayidirolikivalavu yofananira yokhala ndi makadi amplifierndikusintha kukula kwa valve yotsegulira molingana ndi chizindikiro chowongolera magetsi.Khadi la amplifier limatenga chizindikiro cholamula (nthawi zambiri chimakhala chamagetsi kapena chapano) ndikuchisintha kukhala chizindikiro chamakono chomwe chimayendetsa valavu yofananira.Chizindikiro chokwezekachi chimayang'anira malo a spool a valve, yomwe imayendetsa kayendedwe ka madzi.
Ma proportional valve amplifiers amathandizira kuwongolera molondola popereka mgwirizano pakati pa chizindikiro cha lamulo ndi kutulutsa kwa valve.Mwachitsanzo, kuwonjezeka kwa 50% kwa chizindikiro cha lamulo kumabweretsa kuwonjezeka kwa 50% kwa madzimadzi.Mulingo wowongolerawu ndi wofunikira kwambiri pamapulogalamu omwe amafunikira kuwongolera bwino kwa kayendedwe ka madzimadzi kapena kuthamanga kwamadzi, monga makina opangira makina ndi makina owongolera.
Monga chipangizo chamagetsi, khadi ya amplifier ilinso ndi zabwino zambiri kuposa machitidwe azikhalidwe a analogi.Imapereka kudalirika kowonjezereka, kubwereza komanso kusinthasintha pakukonza ma siginecha.Makhadi amakono amplifier nthawi zambiri amakhala ndi ma microprocessors a ntchito zapamwamba monga kuwongolera ma siginecha, kuwunika, ndi ntchito zolumikizirana.
Kuphatikiza kwa ma hydraulic proportional valves ndi makadi amplifier kumapereka maubwino angapo pama hydraulic system.Choyamba, imathandizira kuwongolera bwino kwakuyenda kwamadzimadzi ndi kuthamanga, kuwongolera magwiridwe antchito ndi magwiridwe antchito.Chachiwiri, imathandizira magwiridwe antchito osalala, omvera osasokoneza pang'ono komanso kugwedezeka.Pomaliza, imathandizira kuwongolera kwakutali ndi makina, ndikupangitsa kuti ikhale yoyenera pamakina ovuta kapena mapulogalamu omwe amafunikira ntchito yakutali.
Mwachidule, ndi hydraulicvalavu yofananira yokhala ndi makadi amplifierndi gawo lofunikira mu dongosolo la hydraulic lomwe limapereka kuwongolera kolondola pakuyenda kwamadzimadzi ndi kuthamanga.Ma proportional valve amplifiers amagwira ntchito yofunika kwambiri pakusintha ma siginecha olamula kukhala ma valve oyendera.Amapereka kuwongolera kolondola, kudalirika ndi ntchito zowonjezera pogwiritsa ntchito mabwalo amagetsi.Kuphatikiza kwa zigawozi kumabweretsa zabwino zambiri ku hydraulic system, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana.
