Isilayishi se-excavator izesekeli XKCH-00022 valve solenoid Ivalve ye-Hydraulic

Uyini umehluko phakathi kwe-valve ye-proportional valve ne-solenoid evamile?

I-valve ye-Proportional wuhlobo olusha lwedivayisi yokulawula amanzi.Ku-valve yokucindezela evamile, i-valve yokugeleza kanye ne-valve yokuqondisa, i-electromagnetic proportional isetshenziswa esikhundleni sengxenye yokulawula yasekuqaleni, ngokusho kukagesi wokufakwayo.
Isignali yegesi ilawula ngokuqhubekayo nangokulinganayo ingcindezi, ukugeleza, noma isiqondiso somfudlana kawoyela ukude.Amavalvu alinganiselayo ngokuvamile asebenza ngesinxephezelo sokucindezela, futhi ingcindezi yokuphumayo nezinga lokugeleza kungase kungathintwa izinguquko zomthwalo.

I-1, i-valve evamile ayilingani nokulawulwa kwesinyathelo esiqhubekayo, iyi-valve ehlanzekile yohlobo olulodwa lwesenzo, isiqondiso sokuvula i-valve, inani lokuvula noma amandla okusetha kwentwasahlobo aqinisekile.
Awukwazi ukushintshwa ngokuya ngezimo zangempela.

2, i-valve yokulingana ilingana nokulawulwa kwesinyathelo esiqhubekayo, ngokusho kwesimo sangempela sishintsha olwazini oluqoqwe ekuqondisweni kwesinxephezelo esizenzakalelayo esiqondiwe, indlela yokuvula i-valve, inani lokuvula nomai-spring set force ilandelwa, ukuze kuzuzwe uchungechunge lwezinguquko eziqhubekayo ezilawulwayo ekuhambeni.Ukulawula ukugeleza kwe-valve kungahlukaniswa ngezinhlobo ezimbili: eyodwa iwukulawula ukushintsha: noma evulekile ngokugcwele, noma ivalwe ngokugcwele, ukugeleza kungaba, noma kuncane, akukho isimo esimaphakathi, njenge-electromagnetic evamile ngokusebenzisa i-valve, i-electromagnetic reversing valve, i-electro-hydraulic reversing. i-valve.Okunye ukulawulwa okuqhubekayo: imbobo ye-valve ingavulwa ngokwesidingo sanoma yiliphi izinga lokuvula, ngaleyo ndlela ilawule ubukhulu bokugeleza, ama-valve anjalo anokulawula okubhaliwe, njengama-throttle valve, kodwa futhi alawulwa nge-elekthronikhi, njenge-proportional. ama-valve, ama-servo valves.

Isimiso sokusebenza se-valve ye-proportional:

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.
I-valve ye-proportional yakhiwe yi-DC proportional electromagnet kanye ne-hydraulic valve.Umnyombo we-valve ye-proportional ukubona ukulawula okuqhubekayo isilinganiso
Kunezinhlobo eziningi zozibuthe olinganiselayo, kodwa umgomo wokusebenza uyafana, wonke athuthukiswa ngokwezidingo zokulawula i-valve elinganayo.
