Proportional electromagnet

Nws tau hais ntau zaus ua ntej hais tias tus tsav tswj ib feem, uas yog ib qho tseem ceeb heev nyob rau hauv lub proportional valve, yog lub electro-mechanical converter uas converts cov hluav taws xob teeb liab mus rau lub displacement teeb liab.Tshooj lus no yuav piav qhia meej.
Qhov tseem ceeb tshaj plaws tswj tsis tau nyob rau hauv hydraulic tswj system yog siab thiab ntws, thiab qhov yooj yim tshaj plaws txhais tau tias tswj cov saum toj no ob tsis yog tswj convection kuj.Ib txoj hauv kev los tswj kev khiav hauj lwm yog ncaj qha electro-hydraulic conversion.Nws siv cov roj hluav taws xob-viscous hydraulic, cov kua nruab nrab uas yog viscous rhiab rau cov teeb liab hluav taws xob, kom ua tiav electro-hydraulic viscosity hloov dua siab tshiab, txhawm rau tswj kev khiav hauj lwm thiab ua tiav lub siab thiab ntws tswj ntawm lub cev.Lub hom phiaj.Obviously, qhov no flow resistance tswj txoj kev yog yooj yim dua, nws tsis xav tau hluav taws xob rau mechanical conversion ntsiab.Txawm li cas los xij, qhov kev siv tshuab no tseem tsis tau mus txog theem thiab cov kev xav tau.
Tam sim no, cov qauv tswj kev khiav hauj lwm uas tuaj yeem paub tau hauv cov tshuab tsim khoom yog qhov kev hloov pauv tsis ncaj ntawm electro-hydraulic los ntawm electro-mechanical converter.Lub input hluav taws xob teeb liab yog hloov mus rau hauv ib tug neeg kho tshuab kom muaj nuj nqis.Electro-mechanical converter yog ib qho ntawm cov khoom tseem ceeb ntawm electro-hydraulic proportional valve, thiab nws lub luag hauj lwm yog los hloov lub amplified input signal tam sim no rau hauv proportional mechanical quantity.
