Kodi cholumikizira cha pampu yamadzi yamagalimoto ndi chiyani?
Mu silinda ya injini ya galimoto, pali njira zambiri zamadzi zoziziritsira madzi, zomwe zimalumikizidwa ku radiator (yomwe imadziwika kuti thanki yamadzi) yomwe imayikidwa kutsogolo kwa galimoto kudzera m'mapaipi amadzi, ndikupanga njira yayikulu yoyendera madzi. Pamwamba pa madzi a injini, pali pampu yamadzi, yomwe imayendetsedwa ndi lamba wa fan kuti ipompe madzi otentha m'njira zamadzi za silinda ya injini ndikupompa m'madzi ozizira. Pambali pa pampu yamadzi, palinso thermostat. Galimoto ikangoyatsidwa (yozizira), siiyatsidwa, kotero kuti madzi ozizira asadutse mu radiator koma amangozungulira mkati mwa injini (yomwe imadziwikanso kuti kayendedwe kakang'ono). Kutentha kwa injini kukafika madigiri 95, kumayatsidwa, ndipo madzi otentha mkati mwa injini amapompedwa mu radiator. Pamene galimoto ikupita patsogolo, mpweya wozizira umawomba pa radiator, kuchotsa kutentha.
Mapampu amadzi a centrifugal amagwiritsidwa ntchito kwambiri mu injini zamagalimoto. Kapangidwe kake koyambira kamakhala ndi zigawo monga nyumba ya pampu yamadzi, mbale yolumikizira kapena pulley, shaft ya pampu yamadzi ndi bearing kapena shaft-mounted bearing, impeller ya pampu yamadzi ndi chipangizo chosindikizira madzi, ndi zina zotero. Ndi gawo lalikulu la magalimoto.
Injini imayendetsa bedi la pampu yamadzi ndi impeller kuti zizungulire kudzera mu pulley. Choziziritsira chomwe chili mu pampu yamadzi chimayendetsedwa ndi impeller kuti zizungulire pamodzi. Pogwiritsa ntchito mphamvu ya centrifugal, chimaponyedwa m'mphepete mwa nyumba ya pampu yamadzi ndikupanga kupanikizika kwina nthawi imodzi, kenako chimatuluka kuchokera mu ngalande yotulutsira madzi kapena chitoliro chamadzi. Pakati pa impeller, kupanikizika kumatsika pamene choziziritsira chikutulutsidwa. Pansi pa kusiyana kwa kupanikizika pakati pa cholowera cha pampu yamadzi ndi pakati pa impeller, choziziritsira chomwe chili mu thanki yamadzi chimakokedwa kulowa mu impeller kudzera mu chitoliro chamadzi, zomwe zimapangitsa kuti choziziritsira chizizungulira mozungulira.
Ma bearing omwe amathandizira shaft ya pampu yamadzi amapaka mafuta. Chifukwa chake, ndikofunikira kuletsa choziziritsira kuti chisatuluke mu mafuta ndikuyambitsa emulsification ya mafuta, komanso kuletsa mafuta kutuluka. Njira zotsekera kuti zisatuluke mu mapampu amadzi zimaphatikizapo zomatira zamadzi ndi ma gasket. Mphete yotsekera yamphamvu ya chomatira chamadzi imayikidwa ndi shaft kudzera mu kusokoneza pakati pa impeller ndi bearing, ndipo mpando wotsekera wosasinthika wa chomatira chamadzi umakanikizidwa mwamphamvu pakhoma la pampu yamadzi, potero kukwaniritsa cholinga chotsekera chomatira.
Chopondera madzi cha pampu yamadzi chimalumikizidwa ku injini kudzera mu gasket yotsekera ndipo chimathandizira zinthu zoyenda monga ma bearing. Palinso mabowo otulutsira madzi pa chopondera madzi cha pampu, chomwe chili pakati pa chopondera madzi ndi chopondera. Chopondera madzi chikatuluka kudzera mu chopondera madzi, chimatha kutulutsidwa kuchokera mu dzenje la chopondera madzi kuti chopondera madzi chisalowe mu dzenje la chopondera madzi, zomwe zingawononge mafuta a chopondera madzi ndikupangitsa dzimbiri la zigawo zake. Ngati chopondera madzi chikutulukabe injini itasiya kugwira ntchito, zimasonyeza kuti chopondera madzi chawonongeka.
Kawirikawiri imayendetsedwa ndi crankshaft ya injini kudzera mu V-belt. Lamba woyendetsa amamangiriridwa pakati pa crankshaft pulley ndi pulley ya pampu yamadzi. Pamene crankshaft ikuzungulira, shaft ya pampu yamadzi imazunguliranso, ndipo shaft ya pampu yamadzi imayendetsa impeller kuti izungulire, motero imasintha mphamvu yamakina kukhala mphamvu ya hydraulic.
Impeller ndiye maziko a ntchito ya pampu yamadzi. Kuyenda kwa impeller yokha ndikosavuta; imangozungulira limodzi ndi shaft. Komabe, chifukwa cha mphamvu ya masamba, kuyenda kwa madzi mu impeller ndi kovuta kwambiri. Kumbali imodzi, imachita kayendetsedwe kogwirizana pamodzi ndi kuzungulira kwa impeller; kumbali ina, nthawi zonse imatulutsidwa kunja kwa impeller yozungulira pansi pa mphamvu ya masamba, ndiko kuti, kuyenda kofanana ndi impeller. Chifukwa chake, m'mimba mwake wakunja kwa impeller, kutalika ndi ngodya ya masamba a impeller, komanso mpata wokhala ndi chivundikiro cha pampu, zimakhudza mwachindunji magwiridwe antchito a pampu.
Zolakwika pakupanga mapampu amadzi a magalimoto nthawi zambiri zimachitika chifukwa cha zifukwa zotsatirazi:
Zomwe zimayambitsa
Youdaoplaceholder0 Kukalamba kwa mphete yotsekera : kumayambitsa kutuluka kwa mpweya woziziritsa ndipo mphete yotsekera iyenera kusinthidwa.
Youdaoplaceholder0 Lamba ndi lolimba kwambiri : limawonjezera kutopa kwa pampu yamadzi. Kulimba kwa lamba kuyenera kusinthidwa.
Youdaoplaceholder0 kuwonongeka kwa antifreeze : Kuzimiririka kwa mkati kumayambitsa kuwonongeka kwa pampu yamadzi, ndipo antifreeze iyenera kusinthidwa.
Youdaoplaceholder0 Kukalamba/kuwonongeka kwa zigawo: Pampu yamadzi yakhala ikugwiritsidwa ntchito kwa nthawi yayitali kapena zigawo zake (monga masamba, mabearing) zatha ndipo ziyenera kusinthidwa.
Zizindikiro wamba
Youdaoplaceholder0 Liwiro losakhazikika lopanda ntchito : M'nyengo yozizira, injini imatha kuyima ndipo liwiro limatha kusinthasintha kwambiri.
Youdaoplaceholder0 kutayikira kwa coolant : Madzi akutuluka pafupi ndi pampu yamadzi, ndipo zizindikiro zamadzi zatsala pamabowo opumira mpweya.
Youdaoplaceholder0 Phokoso losazolowereka : Phokoso losazolowereka la mabearing kapena ma impeller.
Kulephera kwa Youdaoplaceholder0 kuzizira kwa makina : Kutentha kwa injini kuli kokwera kwambiri, ndipo mphamvu yoyendera madzi ozizira yachepa.
Ndikofunikira kuchita kukonza nthawi yake mukazindikira zizindikiro zomwe zili pamwambapa kuti mupewe kuwonongeka kwa injini komwe kumachitika chifukwa cha kulephera kwa pampu yamadzi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
