Oyenera Volvo proportional rotary solenoid vavu 23871484

1. Mitundu ndi mitundu ya ma electro-hydraulic proportional valves pamakina omanga

Ma valve a electro-hydraulic proportional valves amaphatikizapo ma valve oyenda molingana, ma valve othamanga olingana ndi ma valve omwe amawongolera. Malinga ndi momwe ma hydraulic amagwirira ntchito pamakina omanga, pali mitundu iwiri ya ma electro-hydraulic proportional valves: imodzi ndi ma spiral cartridge proportional valves, ndipo ina ndi ma slide valve proportional valves.

Vavu ya spiral cartridge ndi chigawo chomwe chinakhazikitsa katiriji ya electromagnetic proportional cartridge pa chipika cha msonkhano wamafuta kudzera mu ulusi. Valve ya spiral cartridge ili ndi mawonekedwe osinthika, kupulumutsa mapaipi ndi mtengo wotsika, etc. Yakhala ikugwiritsidwa ntchito mochulukira m'makina omanga m'zaka zaposachedwa.

Chomwe chimagwiritsidwa ntchito mozungulira katiriji mtundu wa proportional valavu uli ndi mitundu iwiri, itatu, inayi ndi yodutsa, njira ziwiri zofananira ndi valavu yofananira, nthawi zambiri imaphatikizidwa ndi zigawo zina kuti apange valavu yophatikizika, kutuluka, kuwongolera kuthamanga; Valavu yanjira zitatu imakhala yochepetsera kuthamanga kwanthawi yayitali, komanso ndi valavu yofananira yomwe imagwiritsidwa ntchito kwambiri pamakina oyendera ma hydraulic system, omwe makamaka amagwiritsa ntchito makina oyendetsa mafuta a hydraulic multi-way valve.

Valavu yochepetsera mphamvu yanjira zitatu imatha kulowa m'malo mwa valavu yachikhalidwe yochepetsera valavu yoyendetsa, yomwe imakhala yosinthasintha komanso yolondola kwambiri kuposa valavu yoyendetsa. Ikhoza kupangidwa kukhala proportional servo control manual multi-way valve monga momwe tawonetsera pa Chithunzi 1. Malingana ndi zizindikiro zosiyana zolowera, valavu yochepetsera mphamvu imapangitsa kuti pistoni yotulutsa ikhale ndi kuthamanga kosiyana kapena kuthamanga kwa kayendedwe kake kuti ikwaniritse kulamulira kofanana kwa kusamutsidwa kwa multivalu. - njira ya valve. Ma valve a njira zinayi kapena zingapo zomangira katiriji amalola kuwongolera kwa munthu aliyense pa chipangizo chogwirira ntchito.
