Kodi valavu yowongolera mafuta agalimoto ndi chiyani?
Valavu yowongolera mafuta agalimoto (OCV valve) ndi gawo lofunikira la makina opaka mafuta a injini, omwe amagwiritsidwa ntchito makamaka kuwongolera molondola gawo la vavu ya injini ndi kuthamanga kwa mafuta, kuti injini igwire bwino ntchito komanso kuti isawononge mafuta.
Tanthauzo ndi ntchito
Valavu yowongolera mafuta (valavu ya OCV) imapangidwa makamaka ndi thupi la valavu (kuphatikiza cholumikizira cha solenoid ndi cholumikizira cha module yowongolera), valavu yotsatsira ndi kasupe wobwerera. Mfundo yogwira ntchito ndikuwongolera mphamvu yoyatsira ndi kuzima kwa cholumikizira cha electromagnetic kudzera mu chizindikiro cha pulse modulation choperekedwa ndi unit yowongolera injini (ECU), kenako ndikupanga mphamvu ya maginito kuti iwongolere momwe valavu yotsatsira imagwirira ntchito, kuti isinthe nthawi zonse ubale wa crankshaft ndi camshaft, kuti ikwaniritse kulamulira kwabwino kwambiri kwa gawo la valavu .
Ndi kusinthaku, ma valve owongolera mafuta amathandizira kuwonjezera magwiridwe antchito a injini, kukonza kukhazikika kwa ntchito, kupereka mphamvu ndi mphamvu zambiri, komanso kukonza mafuta osawononga komanso kuchepetsa mpweya woipa.
Mtundu ndi kapangidwe kake
Ma valve owongolera mafuta akhoza kugawidwa m'magulu awiri: ma valve owongolera mafuta ndi ma valve oteteza. Ntchito yayikulu ya pressure control ndiyo kulamulira kuthamanga kwa madzi m'dongosolo kuti apewe kuwonongeka kwa mafuta chifukwa cha kuthamanga kwambiri; Valavu yoteteza imagwira ntchito polepheretsa pressure control kuti iteteze kuti chubu chisasweke chifukwa cha kuthamanga kwambiri.
Kuphatikiza apo, pali chosinthira mphamvu ya mafuta chogwirizana ndi dera. Ngati mphamvu ya mafuta siili yokwanira, chosinthiracho chidzatseka ndikuyambitsa kuwala kwa alamu ya mphamvu ya mafuta yochepa pa chipangizo chagalimoto .
Malo ndi ntchito
Valavu yowongolera mafuta nthawi zambiri imayikidwa mu gawo la silinda ya injini, malo ake enieni amakhala kumbuyo kwa pulley ya camshaft mbali zonse ziwiri, motsatana yomwe imayang'anira ntchito zolowetsa ndi kutulutsa. Mavavu awa amawoneka ngati cylindrical ndipo ali ndi pulagi pamwamba yomwe imalumikiza mawaya awiri . Kuphatikiza apo, pali mavavu ena ofunikira owongolera mafuta mu dongosololi, monga valavu yomwe ili m'thupi la silinda, ntchito yayikulu ndikuyendetsa kuyenda kwa mafuta kupita ku matailosi akuluakulu ndi vvt; Ina imagwira ntchito ngati valavu yobwezera mafuta kuti iwonetsetse kuti mafuta akhoza kubwezeretsedwa mu poto yamafuta galimoto ikazima.
Ntchito yaikulu ya valavu yowongolera mafuta a galimoto ndikuwongolera ndikuletsa kupanikizika kwa makina opaka mafuta a injini kuti kusakhale kokwera kwambiri. Mwa kuchepetsa kupanikizika kwakukulu kwa makinawo, kumaletsa kupanikizika kwakukulu kuti kuwononge zigawo za makina opaka mafuta ndikuletsa kutayikira kwa mafuta. Vavu yowongolera mafuta imapangidwa ndi gulu la thupi ndi gulu la actuator, logawidwa m'magulu a mipando imodzi, mndandanda wa mipando iwiri, mndandanda wa manja ndi mndandanda wodziyendetsa wokha wa mndandanda wazinthu zinayi, mndandanda uliwonse uli ndi ntchito yake yapadera, zabwino ndi zoyipa zake pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
Udindo weniweni
Chepetsani kupanikizika kwakukulu kwa dongosolo: valavu yowongolera mafuta powongolera mafuta operekedwa pampu yamafuta, kuti mafuta operekedwa pampu yamafuta asapitirire kwambiri, makamaka pa liwiro lalikulu, mafuta operekedwa pampu yamafuta ndi akulu kwambiri, kuthamanga kwa mafuta kumawonjezeka kwambiri, ndiye kuti valavu yowongolera mafuta ndiyofunikira kwambiri.
Kuteteza kuwonongeka kwa zigawo za dongosolo la mafuta: Kupanikizika kwambiri kwa mafuta kungayambitse valavu ya hydraulic tasht kutseka molakwika, kupanikizika kwa silinda kugwa, komanso kungayambitse kuphulika kwa machubu. Vavu yowongolera mafuta imateteza dongosolo la mafuta kuti lisawonongeke powongolera kupanikizika.
imatsimikizira kuti injini ikugwira ntchito bwino komanso mokhazikika: mu injini yosinthira nthawi ya valve yosinthika, valavu yowongolera mafuta imatsimikizira kusintha kwa gawo la camshaft mwa kuwongolera molondola kusintha kwa njira yamafuta, kuti zitsimikizire kuti injiniyo ikhoza kukwaniritsa bwino ntchito pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
Zotsatira zolakwika
Ngati valavu yowongolera mafuta yalephera, ingayambitse galimoto kuyima poyendetsa, ndipo kuthamanga kwa mafuta kudzakwera modabwitsa, zomwe zimakhudza magwiridwe antchito a galimoto, monga momwe chisakanizocho chili chokhuthala kwambiri, utsi wakuda wochokera mu chitoliro chotulutsa utsi, komanso mphamvu imachepa. Kuthamanga kwambiri kwa mafuta kungayambitsenso kugwiritsa ntchito mafuta ambiri, kutulutsa utsi wambiri, komanso kuthamanga kosakhazikika, zomwe zimawonjezera zoopsa zachitetezo komanso mavuto azachuma mgalimoto. Chifukwa chake, valavu yowongolera mafuta ikapezeka kuti ili ndi vuto, iyenera kuthetsedwa nthawi yomweyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
