I-Excavator solenoid valve 457-9878 i-hydraulic futha i-valve ye-solenoid elinganayo

I-1, isakhiwo se-valve esilinganiselwe.

I-valve ye-Proportional wuhlobo olusha lwedivayisi yokulawula amanzi.Ingcindezi, ukugeleza, noma isiqondiso somfudlana kawoyela singalawulwa ukude ngokuya ngesignali kagesi yokufaka ngokuqhubekayo nangokulingana.I-valve yokulingana yakhiwe izingxenye ezimbili: idivayisi yokuguqula i-electro-mechanical proportional kanye ne-hydraulic control valve body.

Kunezinhlobo eziningi zozibuthe kagesi abalinganayo, kodwa umgomo wokusebenza uyafana, futhi wonke athuthukiswa ngokwezidingo zokulawula zevalvu yokulingana.Umsebenzi wawo ukuguqula ngokuqhubekayo nangokulinganayo isignali kagesi yokufaka ibe amandla omshini kanye nokukhiphayo, futhi lokhu okulandelayo kukhipha ingcindezi nokugeleza ngokulinganayo nangokuqhubekayo ngemva kokwamukela amandla emishini kanye nokugudluza.

2. Isimiso sokusebenza se-valve yokulinganisa.

Isignali yomyalo ikhuliswa yi-proportional amplifier, kanye ne-proportional output yamanje ku-solenoid elinganayo ye-valve yokulingana, amandla okukhipha i-solenoid alinganayo kanye nokunyakaza okulinganayo kwesikhundla somgogodla we-valve, ungakwazi ukulawula ngokulinganayo ukugeleza kokugeleza kwe-liquid futhi shintsha isiqondiso sokugeleza koketshezi, ukuze uzuze isikhundla noma ukulawulwa kwesivinini se-actuator.Kwezinye izinhlelo zokusebenza ezidinga isikhundla esiphezulu noma ukunemba kwesivinini, isistimu yokulawula iluphu evaliwe ingase yakhelwe ngokuthola ukugudluka noma isivinini se-actuator.

Isimiso se-proportional solenoid valve

Isekelwe esimisweni se-valve yokushintsha i-solenoid: lapho amandla enqanyulwa, intwasahlobo icindezela umgogodla wensimbi ngokuqondile esihlalweni, ivala i-valve.Lapho ikhoyili inikwa amandla, amandla kazibuthe kagesi aphumayo anqoba amandla asentwasahlobo futhi aphakamise umongo, ngaleyo ndlela avule ivalvu.I-proportional solenoid valve yenza izinguquko ezithile esakhiweni se-solenoid on-off valve: amandla asentwasahlobo namandla kazibuthe kagesi abhalansi ngaphansi kwanoma iyiphi ikhoyili yamanje.Ubukhulu bekhoyili yamanje noma usayizi wamandla kazibuthe kagesi buzothinta ukushaywa kwe-plunger nokuvulwa kwevalvu, futhi ukuvulwa kwevalvu (izinga lokugeleza) kanye nekhoyili yamanje (isignali yokulawula) inobudlelwano obuhle bomugqa. .Amavalvu e-solenoid asebenzayo aqondile ageleza ngaphansi kwesihlalo.I-medium igeleza ngaphansi kwesihlalo se-valve, futhi isiqondiso saso samandla siyafana namandla kazibuthe kagesi, kodwa okuphambene namandla asentwasahlobo.Ngakho-ke, kuyadingeka ukusetha isamba samanani okugeleza amancane ahambisana nobubanzi bokusebenza (ikhoyili yamanje) esimweni sokusebenza.Lapho amandla ecishiwe, i-valve ye-Drake liquid proportional solenoid iyavalwa (ngokuvamile ivaliwe).

Umsebenzi we-proportional solenoid valve

Ukulawulwa kwe-Throttle yezinga lokugeleza kufinyelelwa ngokulawulwa kagesi (yebo, ukulawulwa kwengcindezi kungabuye kufezwe ngezinguquko zesakhiwo, njll.).Njengoba ilawula i-throttle, kufanele kube nokuphelelwa amandla.
