Kodi pampu ya galimoto ndi chiyani?
Pampu yamadzi yamagalimoto ndi gawo lofunika kwambiri la makina oziziritsira injini, ntchito yayikulu ndikuyendetsa impeller kuti izungulire, kuti choziziritsira chizizungulira mu injini, kuti injini ikhale pamalo oyenera kutentha. Pampu nthawi zambiri imakhala ndi thupi la pampu, impeller, mphete yonyamula ndi yotsekera ndi zinthu zina, mfundo yake yogwirira ntchito ndikupanga mphamvu ya centrifugal kudzera mu kuzungulira kwa impeller, choziziritsira chimachotsedwa mu thanki yamadzi ndikutumizidwa ku injini, ndikupanga kuzungulira.
Pali mitundu yambiri ya mapampu a magalimoto, kuphatikizapo mapampu amakina ndi mapampu amagetsi. Pampu yamakina imayendetsedwa ndi crankshaft ya injini, yomwe ndi yosavuta koma imagwiritsa ntchito mphamvu zinazake za injini ndipo imapanga phokoso. Pampu yamagetsi imayendetsedwa ndi mota yamagetsi, yomwe ingachepetse kugwiritsa ntchito mphamvu ya injini ndikuchepetsa phokoso, makamaka kuti madzi azitha kuyenda bwino pa liwiro lochepa komanso losagwira ntchito. Kuphatikiza apo, zinthu zomwe zili pampuyo ndizosiyana, monga mapampu onse a aluminiyamu ndi mapampu apulasitiki, omwe ali ndi mawonekedwe opepuka komanso oletsa dzimbiri, motsatana.
Ngati pampu yalephera, ingayambitse mavuto monga kutentha kwambiri kapena kutayikira kwa madzi mu injini, zomwe zingakhudze momwe imagwirira ntchito nthawi zonse. Chifukwa chake, kuyang'anira ndi kusamalira pampu nthawi zonse ndiye chinsinsi chotsimikizira kuti injini ikugwira ntchito bwino.
Pampu yamadzi yamagalimoto imagwira ntchito yofunika kwambiri mu makina oziziritsira, ndipo ntchito yake yayikulu ndikuyendetsa kayendedwe ka coolant kuti injini ikhale ndi kutentha koyenera kugwira ntchito pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito. Mwa kuwonjezera kupanikizika kwa coolant, pampuyo imaonetsetsa kuti coolant ikuyenda bwino mu netiweki yonse yoziziritsira, motero imalimbikitsa kuzungulira kosalekeza kwa coolant pakati pa radiator ndi block ya injini, zomwe zimathandiza kuti kutentha kwa injini kusawonongeke.
Njira yogwirira ntchito ya pampu ndikuzungulira bearing ndi impeller kudzera mu lamba wa injini, kenako ndikuyendetsa coolant mu pampu kuti izungulire pamodzi. Pogwiritsa ntchito mphamvu ya centrifugal, coolant imaponyedwa m'mphepete mwa chipolopolo cha pampu, ndikupanga mphamvu yofanana, ndipo pamapeto pake imatuluka kudzera mu potulukira madzi kapena chitoliro cha madzi. Pali njira zambiri zamadzi mu silinda ya injini yagalimoto kuti madzi ozizira aziyenda, ndipo njirazi zimalumikizidwa ndi radiator kutsogolo kwa galimoto kudzera mu chitoliro cha madzi, ndikupanga njira yayikulu yoyendera madzi.
Kuphatikiza apo, nthawi zambiri pamakhala thermostat pafupi ndi pampu. Galimoto ikangoyatsidwa, thermostat imazimitsidwa, ndipo madzi ozizira amangozungulira mkati mwa injini ndipo samayenda kudzera mu thanki yamadzi. Kutentha kwa injini kukafika pamtengo winawake (nthawi zambiri kupitirira madigiri 95), thermostat imatsegulidwa, madzi otentha mu injini amalowetsedwa mu thanki yamadzi, kenako mpweya wozizira m'galimoto umadutsa mu thanki yamadzi kuti ukwaniritse kutentha koyenera.
Mphamvu ya kusintha kwa pampu yamadzi pa injini siinganyalanyazidwe. Pakapita nthawi, pampu ikhoza kulephera chifukwa cha kuwonongeka, kukalamba kwa zisindikizo kapena mabearing owonongeka, zomwe zimapangitsa kuti kuzizira kuyende bwino, zomwe zingayambitse kutentha kwambiri kwa injini, komanso, nthawi zina kuwonongeka kwa injini. Chifukwa chake, kusintha pampu nthawi yake ndi njira yofunika kwambiri yotetezera, yomwe ingapewe kuwonongeka kwa injini chifukwa cha kulephera kwa makina oziziritsira ndikuwonjezera moyo wa injini.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina pandi tsamba!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd.yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zalandiridwakugula.
