Kodi valve yowongolera mafuta pamagalimoto ndi chiyani
Valavu yowongolera mafuta pamagalimoto (valavu ya OCV) ndi gawo lofunikira kwambiri pamakina opangira mafuta a injini, omwe amagwiritsidwa ntchito kwambiri kuwongolera moyenera gawo la valve ya injini ndi kuthamanga kwamafuta, kuti akwaniritse bwino ntchito ya injini komanso kutsika kwamafuta.
Tanthauzo ndi ntchito
Valve yowongolera mafuta (valavu ya OCV) imapangidwa makamaka ndi thupi la valavu (kuphatikiza koyilo ya solenoid ndi cholumikizira cholumikizira), valavu ya slide ndi kasupe wobwerera. Mfundo yogwirira ntchito ndikuwongolera mphamvu ndikuchotsa koyilo yamagetsi kudzera pamagetsi osinthika operekedwa ndi gawo lowongolera injini (ECU), kenako ndikupanga mphamvu yamaginito kuti ilamulire momwe ma valavu amachitira, kuti asinthe mosalekeza ubale wanthawi pakati pa crankshaft ndi camshaft, kuti mukwaniritse gawo lowongolera bwino la valavu.
Ndi kusinthaku, ma valve owongolera mafuta amathandizira kukulitsa mphamvu ya injini, kukonza bata, kupereka torque yayikulu ndi mphamvu, komanso kupititsa patsogolo chuma chamafuta ndikuchepetsa kutulutsa mpweya.
Mtundu ndi kapangidwe
Ma valve owongolera mafuta amatha kugawidwa m'magulu awiri: ma valve owongolera mafuta ndi ma valve oteteza. Ntchito yayikulu ya wowongolera kukakamiza ndikuwongolera kukakamiza kwadongosolo kuti zisawonongeke dongosolo lamafuta chifukwa cha kuthamanga kwambiri; Valavu yoteteza imathandizira kulephera kwa chowongolera kuti chiwopsezo cha chubu chitha kusweka chifukwa cha kupanikizika kwambiri.
Kuphatikiza apo, pali chosinthira chowongolera kuthamanga kwamafuta chokhudzana ndi dera. Kuthamanga kwamafuta kukakhala kosakwanira, chosinthiracho chimatseka ndikuyambitsa alamu yotsika yamafuta pa chida chagalimoto.
Malo ndi ntchito
Valavu yowongolera mafuta nthawi zambiri imayikidwa mu silinda ya injini, malo enieniwo amakhala kumbuyo kwa pulley ya nthawi ya camshaft mbali zonse ziwiri, motsatana ndi ntchito yolowera ndi kutulutsa. Ma valve awa ndi owoneka ngati cylindrical ndipo ali ndi pulagi pamwamba yomwe imalumikiza mawaya awiri. Kuphatikiza apo, palinso ma valve ena ofunikira owongolera mafuta m'dongosolo, monga valavu yomwe ili mu thupi la silinda, ntchito yayikulu ndikuwongolera kayendedwe ka mafuta ku tile yayikulu ndi vvt; Zina zimakhala ngati valavu yobwezeretsa mafuta kuti zitsimikizire kuti mafuta atha kubwezeredwa ku poto yamafuta galimoto ikatha.
Ntchito yayikulu ya valavu yowongolera mafuta pamagalimoto ndikuwongolera ndikuletsa kupanikizika kwa makina opaka mafuta a injini kukhala okwera kwambiri. Pochepetsa kupanikizika kwakukulu kwa dongosololi, zimalepheretsa kupanikizika kwakukulu kuti zisawononge zigawo za mafuta odzola ndikuletsa kutuluka kwa mafuta. Valavu yoyang'anira mafuta imapangidwa ndi kusonkhana kwa thupi ndi msonkhano wa actuator, wogawidwa m'magulu ampando umodzi, mndandanda wa mipando iwiri, mndandanda wa manja ndi mndandanda wodziyendetsa wokha wa mndandanda anayi, mndandanda uliwonse uli ndi ntchito yake yapadera, ubwino ndi zovuta pansi pazikhalidwe zosiyanasiyana zogwirira ntchito. pa
Ntchito yeniyeni
Chepetsani kupanikizika kwakukulu kwa dongosolo : valavu yowongolera mafuta powongolera mafuta a pampu yamafuta, kuti mupewe kuthamanga kwa mafuta pampu yamafuta ndikokwera kwambiri, makamaka pa liwiro lalikulu, mafuta a pampu yamafuta ndi akulu kwambiri, kuthamanga kwamafuta kumachulukirachulukira, ndiye valavu yowongolera mafuta ndiyofunikira kwambiri.
Pewani kuwonongeka kwa zida zopangira mafuta : Kuchuluka kwamafuta kumatha kupangitsa kuti ma hydraulic tasht valve atseke molakwika, kuthamanga kwa silinda kutsika, komanso kungayambitse kuphulika kwa chubu. Valve yowongolera mafuta imateteza dongosolo lopaka mafuta kuti lisawonongeke powongolera kupanikizika.
imawonetsetsa kuti injini ikuyenda bwino komanso yokhazikika: mu injini yosinthira valavu yosinthira, valavu yowongolera mafuta imatsimikizira kusintha kwa camshaft mwa kuwongolera molondola kusintha kwa ndimeyi yamafuta, kuti zitsimikizire kuti injiniyo imatha kugwira ntchito bwino pansi pamikhalidwe yosiyanasiyana yogwirira ntchito.
Zotsatira zoyipa
Ngati valavu yoyendetsa mafuta ikulephera, ikhoza kuchititsa kuti galimotoyo iwonongeke panthawi yoyendetsa galimoto, ndipo kuthamanga kwa mafuta kudzakwera mosadziwika bwino, zomwe zimakhudza momwe galimotoyo ikuyendera, monga kusakaniza kumakhala kochuluka kwambiri, utsi wakuda kuchokera ku chitoliro chotulutsa mpweya, ndipo mphamvu imafooka. Kuchuluka kwamafuta kungayambitsenso kuchulukirachulukira kwamafuta, kutulutsa utsi wambiri, komanso kuthamanga kosagwira ntchito, kukulitsa chiwopsezo chachitetezo komanso kulemetsa kwachuma kwagalimoto. Choncho, valavu yolamulira mafuta ikapezeka kuti ndi yolakwika, iyenera kuthetsedwa mwamsanga.
paNgati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
