Loader excavator accessories 201-0950 solenoid valve los ua ke

Electromagnetic proportional valve ua hauj lwm txoj cai thiab nrhiav kom tau:

Valve tswj ntawm ntws tuaj yeem muab faib ua ob hom:
Ib qho yog hloov tswj: qhib siab lossis kaw tag nrho, tus nqi ntws yog qhov loj lossis me, tsis muaj lub xeev nruab nrab, xws li cov khoom siv hluav taws xob zoo tib yam los ntawm cov li qub, electromagnetic reversing li qub, electro-hydraulic reversing li qub.
Lwm qhov yog kev tswj tsis tu ncua: qhov chaw nres nkoj valve tuaj yeem qhib tau raws li qhov xav tau ntawm txhua qib ntawm kev qhib, yog li tswj qhov loj ntawm qhov ntws los ntawm, xws li li qub muaj kev tswj tuav tswj, xws li lub kaw lus valve, tab sis kuj tswj tau hluav taws xob, xws li proportional. li qub, servo valve.
Yog li lub hom phiaj ntawm kev siv proportional valve los yog servo valve yog: kom ua tiav cov dej ntws tswj los ntawm kev tswj hluav taws xob (ntawm chav kawm, tom qab cov qauv kev hloov pauv tuaj yeem ua tiav kev tswj siab, thiab lwm yam), vim nws yog throttling tswj, yuav tsum muaj lub zog poob, servo. valve thiab lwm yam li qub yog qhov sib txawv, nws lub zog poob ntau dua, vim tias nws xav tau ib qho kev khiav dej num los tswj kev ua haujlwm ntawm pre-theem tswj roj Circuit Court.

Lub ntsiab valve ntawm lub servo valve feem ntau zoo ib yam li lub reversing valve yog ib tug swb valve, tab sis lub reversing ntawm lub valve tub ntxhais tsis yog tsav los ntawm ib tug electromagnet, tab sis los ntawm lub hydraulic siab tso zis ntawm lub pre-theem valve, uas yog. zoo ib yam li electro-hydraulic reversing valve, tab sis lub pre-theem valve ntawm electro-hydraulic reversing valve yog solenoid reversing valve, thiab pre-theem valve ntawm lub servo valve yog lub nozzle baffle valve lossis dav hlau yeeb nkab valve nrog zoo dua. dynamic yam ntxwv.
Uas yog hais tias, lub ntsiab valve ntawm lub servo valve yog tswj los ntawm cov zis siab ntawm pre-theem valve, thiab lub siab ntawm pre-theem valve los ntawm inlet p ntawm lub servo valve, yog hais tias lub siab ntawm p. qhov chaw nres nkoj tsis txaus, lub pre-theem valve tsis tuaj yeem tso tawm lub siab txaus los txhawb lub ntsiab spool nkaus.
