isilayishi Ikhwalithi ephezulu ye-Proportional solenoid valve 25/222913

     Amaphutha ajwayelekile we-solenoid valve 

Ukuvuza komoya kuzodala ukucindezelwa komoya okunganele, okwenza kube nzima ukuvula nokuvala i-valve ephoqelelwe, ngoba i-gasket yokuvala yonakalisiwe noma i-spool valve igugile futhi imigodi eminingana ibanjwe. Lapho ubhekana nokuhluleka kwe-valve ye-solenoid yesistimu yokushintsha, isikhathi esifanele kufanele sikhethwe ukubhekana ne-valve ye-solenoid uma ingasebenzi. Uma ukucubungula kungeke kuqedwe ngaphakathi kwegebe lokushintsha, uhlelo lokushintsha lungamiswa futhi luphathwe ngokuzolile.

Ukushayela kuhlukile. Idivayisi yokushayela ye-valve ye-proportional iwuzibuthe we-proportional, futhi idivayisi yokushayela ye-servo valve iyinjini yamandla noma i-torque motor, futhi imingcele yokusebenza ihlukile. I-Hysteresis, indawo efile emaphakathi, umkhawulokudonsa, ukunemba kokuhlunga nezinye izici zihlukile, ngakho-ke izikhathi zokufaka isicelo zihlukile, ama-servo valves nama-servo proportional valves asetshenziswa kakhulu ezinhlelweni zokulawula iluphu evaliwe, ama-valve alinganayo kwezinye izakhiwo asetshenziswa ikakhulukazi ku-loop evulekile. amasistimu okulawula kanye nezinhlelo zokulawula isivinini esivaliwe.

Amandla okufakwayo wevalvu evamile yokulinganisa makhulu, ngokuyisisekelo kumakhulu we-Ma kuya ku-1 amp noma ngaphezulu, kuyilapho amandla okufaka e-valve evamile mancane, ngokuyisisekelo kumashumi e-MA; Ukunemba kokulawula kwe-valve yokulinganisa kuncane kancane, i-hysteresis inkulu kune-valve ye-servo, futhi ukunemba kokulawula kwe-valve evamile kuphezulu, kodwa izidingo zamafutha nazo ziphakeme.

Kuyaqondwa kusukela esakhiweni ukuthi i-spool ye-valve yokulinganisa ilinganiswe ngamandla kagesi kanye nomfutho we-hydraulic kanye namandla asentwasahlobo, kuyilapho i-valve evamile ilinganiswa nokucindezela kwe-hydraulic, ngakho-ke i-valve yokulingana ayinayo inzuzo ekulawuleni ukugeleza okukhulu nokucindezela okukhulu. Kunama-valve alinganayo Z imikhiqizo yokuqala avuliwe, okufanele kube isizathu sokuthi kungani ibizwa ngokuthi ama-proportional valves.

Ekusetshenzisweni, i-valve evamile isetshenziswa kabanzi, hhayi nje kuphela ukuthi ingasetshenziselwa isikhundla esiqondile, isivinini nokunye ukulawula, kodwa futhi ngesenzo, ngakho-ke amandla okuqondisa imoto oyishayelayo iyisistimu ye-servo, okunzima ukuyifinyelela ngokulinganayo. ama-valve.
