Vavu yofukula solenoid 198-4607 hydraulic pump proportional solenoid valve

Proportional solenoid valve ndi mtundu watsopano wamagetsi owongolera omwe ali ndi mitundu yambiri yamapangidwe. Chofala ndi thupi lalikulu ndi valavu yoyendetsa ndege. Spool mu valve yoyendetsa ndege imapangidwa kukhala taper inayake. Kenako, chipangizo chophatikizira chowunikira ndikuyendetsa galimoto chimagwiritsidwa ntchito kuwongolera kuchuluka kwamafuta nthawi yomweyo, kuti akwaniritse cholinga chowongolera mosadukiza kuchuluka kwamafuta a valve yayikulu. Chidule chachidule chotsatirachi chidzawonetsa ntchito ya valavu yofanana ndi solenoid ndi mfundo yogwirira ntchito ya proportional solenoid valve.

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).

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.
