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. Ama-valve alinganiselayo ngokuvamile asebenza ngokunxeshezelwa kwengcindezi, 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.
