Izesekeli zomshini we-Excavator 3771417 TM94502 i-valve ye-solenoid elinganayo

Isakhiwo se-valve esilinganiselwe kanye nomgomo wokusebenza

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 yokulinganisa yakhiwe izingxenye ezimbili: idivayisi yokuguqula ngokulinganayo kagesi kanye nemishini kanye nomzimba we-valve yokulawula i-hydraulic.
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.
