Vavu yofukula solenoid 457-9878 hydraulic pump proportional solenoid valve

1, mawonekedwe a valve.

Proportional valve ndi mtundu watsopano wa chipangizo chowongolera ma hydraulic. Kuthamanga, kuyenda, kapena komwe kumayendera mafuta kumatha kuwongoleredwa patali malinga ndi chizindikiro chamagetsi cholowera mosalekeza komanso molingana. Valavu yofananira imapangidwa ndi magawo awiri: chipangizo chosinthira ma electro-mechanical proportional conversion and hydraulic control valve body.

Pali mitundu yambiri ya ma electromagnetic ofananira, koma mfundo yogwira ntchito ndiyofanana, ndipo onse amapangidwa molingana ndi zofunikira zowongolera ma valve olingana. Ntchito yake ndikusintha mosalekeza komanso molingana ndi chizindikiritso chamagetsi kuti chikhale mphamvu yamakina ndi kusuntha, ndipo chomalizacho chimatulutsa kukakamiza ndikuyenda molingana ndi mosalekeza pambuyo povomereza mphamvu yamakina ndi kusamuka.

2. Mfundo yogwira ntchito ya valve yolingana.

Chizindikiro cha lamulo chimakulitsidwa ndi amplifier yofananira, ndi mphamvu yofananira ndi yofanana ndi solenoid ya proportional valavu, mphamvu yofananira ya solenoid ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. kusintha njira ya madzi otaya, kuti akwaniritse udindo kapena liwiro kulamulira actuator. M'mapulogalamu ena omwe amafunikira malo apamwamba kapena kulondola mwachangu, makina owongolera otsekeka amathanso kupangidwa pozindikira kusuntha kapena kuthamanga kwa chowongolera.

Mfundo ya proportional solenoid valve

Zimatengera mfundo ya solenoid switch valve: mphamvu ikatha, kasupe amakankhira pachimake chachitsulo molunjika pampando, kutseka valavu. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yamagetsi yomwe imatuluka imagonjetsa mphamvu ya masika ndikukweza pachimake, motero imatsegula valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a solenoid on-off valve: mphamvu yamasika ndi mphamvu yamagetsi yamagetsi zimayenderana pansi pa koyilo iliyonse. Kukula kwa koyilo yamakono kapena kukula kwa mphamvu yamagetsi yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa valavu, ndipo kutsegula kwa valve (kuthamanga kwa magazi) ndi koyilo yamakono (chizindikiro chowongolera) zimakhala ndi mgwirizano wabwino kwambiri. . Direct acting proportional solenoid mavavu amayenda pansi pa mpando. Sing'anga imayenda pansi pa mpando wa valve, ndipo mphamvu yake ndi yofanana ndi mphamvu yamagetsi, koma mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa chiwerengero cha ziwerengero zazing'ono zomwe zimagwirizana ndi mtundu wa ntchito (coil current) mu kayendetsedwe ka ntchito. Mphamvu ikazimitsidwa, valavu ya Drake liquid proportional solenoid imatsekedwa (nthawi zambiri imatsekedwa).

Proportional solenoid valve ntchito

Kuwongolera kwamtundu wa kuthamanga kumatheka ndi mphamvu zamagetsi (zowonadi, kuwongolera kuthamanga kungathenso kupindula ndi kusintha kwapangidwe, etc.). Popeza ndi throttle control, payenera kukhala kutaya mphamvu.
