Excavator solenoid vharafu 25-220992hydraulic pombi proportional solenoid vharafu

Rudzi rwevharuvhu yakaenzana
Kurongeka kunoenderana neiyo proportional valve control modhi inoreva kupatsanurwa kunoenderana nemagetsi uye mekiniki shanduko modhi muvhavhavha yekudzora yevhavhavha yakaenzana, uye chikamu chemagetsi chekudzora chine mafomu akasiyana senge proportional electromagnet, torque mota, DC. servo mota, nezvimwewo.
(1) Electromagnetic mhando
Iyo electromagnetic mhando inoreva kune yakaenzana vharafu inoshandisa yakaenzana electromagnet seyemagetsi-mechanicha inoshandura chinhu, uye yakaenzana electromagnet inoshandura yekuisa yazvino siginecha kuita simba uye displacement mechanicha chiratidzo chinobuda. Wobva wadzora kudzvanywa, kuyerera uye kutungamira paramita.
(2) Mhando yemagetsi
Mhando yemagetsi inoreva vheji yakaenzana inoshandisa iyo DC servo mota seyemagetsi-mechanicha inoshandura chinhu, uye iyo DC servo mota inopinza chiratidzo chemagetsi. Shandura kune inotenderera inofamba kumhanya, uyezve kuburikidza ne screw nut, giya rack kana giya CAM yekudzikisa mudziyo uye shanduko mashini, simba rekubuda uye kutama, kuwedzera kutonga kwe hydraulic paramita.
(3) electrohydraulic
Iyo electro-hydraulic mhando inoreva kune yakaenzana vharafu ine chimiro che torque mota uye nozzle baffle senhanho yekudzora mutyairi. Pinza masaini akasiyana emagetsi kune torque mota, uye inoburitsa kusimuka kana angular kusimuka kuburikidza nebaffle yakabatana nayo (dzimwe nguva armature ye torque mota ndiyo baffle), shandura chinhambwe pakati pebaffle uye nozzle, kuitira kuti mafuta anoyerera kuramba. yemhino inoshandurwa, uye wozodzora iyo paramita yekupinza.
