I-Excavator hydraulic futha i-valve ye-solenoid engu-200-6210

I-spool ye-proportional solenoid valve ilawulwa ngozibuthe kagesi abalinganayo, ukuze ingcindezi yokuphumayo noma ukugeleza kulingane nokokufaka kwamanje. Ngakho-ke, ingcindezi yokuphumayo noma ukugeleza kungalawulwa ngokuqhubekayo ngokushintsha isignali yokufaka. Amanye ama-valve nawo anomsebenzi wokulawula usayizi wokugeleza nesiqondiso. Ngokusho kwe-valve ye-proportional ingabuye ihlukaniswe: i-valve ye-pressure proportional, i-valve yokugeleza ye-proportional, i-valve ehlehlisayo izigaba ezintathu.
I-valve ye-proportional isetshenziselwa ukufaka esikhundleni sengxenye yokulawula yasekuqaleni ngozibuthe olinganiselayo ku-valve yokucindezela evamile, i-valve yokugeleza kanye ne-valve yokuqondisa, kanye nokulawula ukude ingcindezi, ukugeleza noma isiqondiso sokugeleza kukawoyela ngokuya ngesignali kagesi yokufaka ngokuqhubekayo nangokulingana. . Ama-valve alinganiselayo ngokuvamile anokusebenza kwesinxephezelo sokucindezela, futhi ukucindezela kokuphumayo nezinga lokugeleza kungase kungathinteki izinguquko zomthwalo.
I-valve elinganayo ingakwazi ukulawula usayizi wokuphumayo ngegagasi le-PWM, futhi okukhiphayo kuyaqhubeka.
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.
