Chofukula cha hydraulic pump solenoid valve proportional solenoid valve TM68401

Makhalidwe a proportional solenoid valves

1) Imatha kuzindikira kusintha kosasunthika kwa kuthamanga ndi kuthamanga, ndikupewa zomwe zimachitika pomwe valavu yotseguka yotseguka imasinthidwa.

2) Kuwongolera kwakutali ndikuwongolera pulogalamu kumatha kuchitika.

3) Poyerekeza ndi kulamulira kwapakatikati, dongosololi limakhala losavuta ndipo zigawozo zimachepetsedwa kwambiri.

4) Poyerekeza ndi hydraulic proportional valve, ndi yaying'ono, yopepuka, yopepuka komanso yotsika mtengo, koma liwiro lake loyankhidwa ndilochepa kwambiri kuposa ma hydraulic system, komanso limakhala lomvera kusintha kusintha.

5) Mphamvu yochepa, kutentha kochepa, phokoso lochepa.

6) Sipadzakhala moto komanso kuwononga chilengedwe. Simakhudzidwa kwambiri ndi kusintha kwa kutentha.

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).
