313-7668 E938H 950K valavu yofananira ya solenoid Hydraulic loader solenoid valve

Valve yoyendetsa kayendedwe kake ndi valavu yofananira ya solenoid, yomwe imachokera ku mfundo ya solenoid on-off valve: Mphamvu ikatha, kasupe amakankhira pachimake pampando, kuchititsa kuti valve itseke. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yopangidwa ndi electromagnetic imapambana mphamvu yamasika ndikukweza pachimake, motero kutsegulira valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a valavu ya solenoid: imapanga malire pakati pa mphamvu yamasika ndi mphamvu yamagetsi yamagetsi pansi pa koyilo iliyonse. Kukula kwa koyilo yapano kapena kukula kwa mphamvu yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa ma valve, ndipo kutsegula kwa valve (kuyenda) ndi koyilo (chizindikiro chowongolera) ndiubwenzi wabwino kwambiri.
Direct acting proportional solenoid valve imayenda pansi pa mpando. Sing'anga imayenda kuchokera pansi pa mpando, ndipo mayendedwe a mphamvu ndi ofanana ndi mphamvu yamagetsi, ndipo mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa maulendo apamwamba komanso ocheperako omwe akugwirizana ndi mtundu wa ntchito (coil current) mu kayendetsedwe ka ntchito. Valavu yofananira ya solenoid ya Drey fluid imatsekedwa (NC, yomwe nthawi zambiri imatsekedwa) mphamvu ikazimitsidwa.
Ngati plunger ndi plunger stopper geometry ndi yathyathyathya, mphamvu yamagetsi yamagetsi imatsika kwambiri pamene kusiyana kwa mpweya kumawonjezeka, zomwe zimapangitsa kuti valavu ikhale yosagwiritsidwa ntchito ngati chowongolera. Choyimitsa chokhacho ndi choyimitsa chopondera ndizomwe zimapangidwira kuti zikhale zomangika, kuti zitheke kukhazikika pakati pa mphamvu yamasika ndi mphamvu yamagetsi yamagetsi pansi pamitundu yosiyanasiyana yamakoyilo apano. Kunja kwa kuyimitsidwa kumapangidwa ngati kondomu, ndipo pamwamba pa plunger amapangidwa ngati bevel yowoneka bwino. Mphamvu ikatha, mphamvu ya masika imatseka valve. Chisindikizo chophatikizika pansi pa plunger chimatsimikizira kuti valavuyo ilibe kutayikira.
