I-Excavator solenoid valve 25-220994 i-hydraulic pump proportional solenoid valve

I-valve ye-solenoid ye-Proportional iyi-valve ekhethekile yokulawula i-solenoid, isimiso sayo sokulawula ukulawula ukuvulwa kwe-valve ngokusebenzisa isignali yomyalo wokufakwa kwangaphandle, ukuze ukugeleza kokulawula nokucindezela kuhlale kugcina isilinganiso esifanayo nesignali yomyalo. Isebenzisa ubuchwepheshe be-"position feedback", obungakwazi ukulungisa ngokunembile indawo ye-valve ngokusho kwesignali yokulawula ukugeleza, ukuze kuzuzwe izidingo zokulawula ezinembile, ngakho-ke isetshenziswa kabanzi ekulawuleni okunembile kwesistimu ye-hydraulic.

Umgomo oyinhloko we-proportional solenoid valve ukuthi isignali yokulawula ukugeleza namandla okulawula asetshenziswa njengomthombo wamandla wekhoyili kagesi, ukuze i-electromagnetic ilawule ukuvulwa kwe-valve, ngakho ukuvulwa kwe-valve kucishe kulingane usayizi wesiginali yokulawula ukugeleza. Ngokuhambisana nokugeleza okuhlukile, indawo yokulawula ngayinye inenani elihlukile lokugeleza, elibuyiselwa kusilawuli sokugeleza, isilawuli sokugeleza singakwazi ukulungisa ibhithi ye-valve ngokusho kwesignali yokuphumayo yosayizi ofanayo nokugeleza lapha.
Ukuze kuzuzwe izimfuneko zokulawula ezinembile.

Uhlobo lwe-valve yokulingana

Ukuhlukaniswa ngokwemodi yokulawula i-valve elinganayo kubhekiselwa ekuhlukaniseni ngokuya ngemodi yokuguqula kagesi neyomshini ku-valve yokulawula umshayeli we-valve elinganayo, futhi ingxenye yokulawula kagesi inezinhlobo ezahlukahlukene ezifana ne-proportional electromagnet, motor torque, DC. i-servo motor, njll.
(1) Uhlobo lwe-electromagnetic

(2) Uhlobo lukagesi

(3) i-electrohydraulic
