Excavator solenoid valve 25-220992hydraulic pump proportional solenoid valve

Uhlobo lwe-valve ebalulekile
Ukuhlukaniswa ngokwendlela ye-Valve Control Mode ehambelana kubhekisele ekuhlukanisweni kwendlela ngokusho kwe-Pilot Control valve ye-valve ye-Pilot ye-valve ehlukile, futhi ingxenye yokulawulwa kukagesi inezindlela ezahlukahlukene ezifana ne-electromagnet ehlukile, i-torque motor, i-DC servo motor, njll.
(1) Uhlobo lwe-electromagnetic
Uhlobo lwe-electromagnetic lusho i-valve ehlukile usebenzisa i-electromagnet enjalo njenge-electromagnet eguqukayo kagesi, futhi i-electromagnet ehambelana ne-electromagnet iguqula isiginali yamanje e-Force kanye nokukhishwa kwezimpawu zomshini. Bese ulawula amapharamitha wokucindezela, ukugeleza kanye nokuqondisa.
(2) Uhlobo kagesi
Uhlobo lukagesi lubhekisela kwi-valve ehlukile kusetshenziswa i-DC Servo motor njengento yokuguqulwa kukagesi, kanye ne-DC Servo Motor izofaka isiginali kagesi. Guqula ukujikeleza isivinini sokunyakaza, bese kuthi nge-isikulufa nati, i-gear rack noma idivaysi ye-gear cam yokunciphisa bese ushintsha inqubo, amandla okukhipha nokufuduka, okuqhubekayo kwamapharamitha we-hydraulic.
(3) Electrohydraulic
Uhlobo lwe-electro-hydraulic lubhekisela kwi-valve ehlukile ngesakhiwo se-torque motor ne-nozzle axable njenge-Pilot Control Stage. Faka amasiginali kagesi ahlukene kwi-torque motor, nokuphuma kokuphuma noma ukuthuthwa kwe-angular ngokusebenzisa i-baffle exhunyiwe nakho (kwesinye isikhathi i-armature ye-torque motor yi-adfle), shintsha ibanga phakathi kwe-azzle nalo i-nozzle lishintshiwe, bese ulawula amapharamitha wokufaka.
