Kodi mphika wowonjezera galimoto ndi chiyani?
Mphika wowonjezera magalimoto, womwe umadziwikanso kuti thanki yowonjezera kapena thanki yothandizira, ndi gawo lofunikira la makina oziziritsira magalimoto. Ntchito yake yayikulu ndikupereka malo owonjezera a choziziritsira, kuyamwa mpweya wochulukirapo ndi kupanikizika komwe kumachitika panthawi yogwira ntchito ya makina oziziritsira, ndikuwonetsetsa kuti makina oziziritsira akugwira ntchito bwino.
Ntchito yoyambira ya mphika wokulitsa
Kuthamanga kwa kuyamwa: Pamene choziziritsira chikuzungulira mu injini, choziziritsira chimakula chifukwa cha kukula kwa kutentha ndi kuzizira. Mphika wokulitsa umayamwa choziziritsira chokulitsa ndikuletsa kuthamanga kwa dongosolo kuti kusakhale kwakukulu kwambiri, motero kuteteza makina oziziritsira ku kuwonongeka.
Mpweya wolekanitsidwa: Choziziritsira chimapanga mpweya panthawi yoyenda, womwe ngati utsala mu dongosolo, ungayambitse kuchepa kwa mphamvu yotaya kutentha. Mphika wokulitsa ukhoza kulekanitsa mpweya uwu, kuonetsetsa kuti choziziritsiracho chili choyera komanso kuti kutentha kukhale koyenera.
Sinthani kuchuluka kwa choziziritsira: mphika wowonjezera ungagwiritsidwenso ntchito ngati chidebe chowonjezera cha choziziritsira, ngati choziziritsira sichikwanira, mutha kuwonjezera choziziritsira kudzera mu izo kuti muwonetsetse kuti injini nthawi zonse imakhala ndi choziziritsira chokwanira kutentha .
Kapangidwe ndi mtundu wa mphika wokulirapo
Pali mitundu iwiri ikuluikulu ya ma POTS okulitsa: amplific expansion ndi high-pressure expansion .
Mphika wowonjezera mpweya: Mtundu uwu wa mphika wowonjezera mpweya sugwirizana mwachindunji ndi makina oziziritsira, ndipo kuchuluka kwake kwa madzi sikungawonetse mokwanira kuchuluka kwa choziziritsira mpweya mu makina oziziritsira. Ngati choziziritsira mpweya sichikwanira, yang'anani makina onse oziziritsira mpweya musanawonjezere choziziritsira mpweya mu mphika wowonjezera mpweya.
Mphika wowonjezera mphamvu yamagetsi: mtundu uwu wa mphika wowonjezera umalumikizidwa mwachindunji ndi makina oziziritsira, ndipo mulingo wamadzimadzi umatha kuwonetsa mwachindunji kuchuluka kwa choziziritsira mu makina oziziritsira, kotero ndikosavuta kuweruza ngati ndikofunikira kuwonjezera choziziritsira.
Malangizo osamalira ndi kugwiritsa ntchito mphika wokulirapo
Kuyang'ana nthawi ndi nthawi: Nthawi ndi nthawi onani mzere wa chizindikiro cha mulingo wamadzimadzi mu mphika wokulirapo kuti muwonetsetse kuti mulingo wamadzimadzi uli pakati pa mulingo wapamwamba ndi wotsika kwambiri. Ngati mulingo wamadzimadzi uli wochepa kwambiri, choziziritsira chiyenera kuwonjezeredwa pakapita nthawi.
Pewani kutsegula pa kutentha kwambiri: musatsegule chivindikiro chokulitsa injini ikatentha, chifukwa kuthamanga kwamkati kumakhala kwakukulu, zomwe zingayambitse ngozi.
Yang'anani valavu yochepetsera kupanikizika: Vavu yochepetsera kupanikizika ndi gawo lofunika kwambiri la mphika wokulitsa. Ngati yalephera, kupanikizika sikungatulutsidwe ndipo kungawononge mphika wokulitsa kapena makina onse ozizira.
Mphika wokulitsa magalimoto uli ndi ntchito zambiri mu makina oziziritsira magalimoto, makamaka kuphatikiza kuyamwa mphamvu, kulekanitsa mpweya ndikuletsa choziziritsira kuti chisatuluke.
Choyamba, mphika wowonjezera umatha kuyamwa kupanikizika komwe kuli mu makina. Injini ikamagwira ntchito, makina oziziritsira amapanga kupanikizika kwina, ngati njira yoziziritsira ipita mwachindunji kumlengalenga, izi zimapangitsa kuti mpweya wozizira utuluke komanso kusintha kwa mankhwala, zomwe zimakhudza kuzizira. Potseka makina ogwiritsira ntchito, mphika wowonjezera umayamwa ndikusunga kupsinjika komwe kumapangidwa ndi makina kuti atsimikizire kuti makinawo akugwira ntchito bwino.
Kachiwiri, mphika wokulitsa umalekanitsa mpweya kuti utsimikizire kuti kutentha kumatuluka bwino. Injini ikagwira ntchito, mpweya umapangidwa mu makina ozizira. Ngati mpweya uwu ukuyenda mu payipi, mpweya udzatsekedwa mu payipi yochotsera kutentha, zomwe zimakhudza momwe kutentha kumatulutsira. Mphika wokulitsa ukhoza kulekanitsa ndi kusunga mpweya uwu kuti uteteze kutsekeka kwa mpweya ndikuwonetsetsa kuti kutentha kumatuluka bwino.
Kuphatikiza apo, mphika wowonjezera umaletsa choziziritsira kuti chisatuluke. Popeza gawo lalikulu la choziziritsira ndi madzi, madziwo amasanduka nthunzi kutentha kwambiri, zomwe zimapangitsa kuti choziziritsira chichepe. Mphika wowonjezerawo wapangidwa ndi njira yotsekedwa kuti choziziritsira chisatuluke nthunzi ndikusunga magwiridwe antchito okhazikika a dongosololi.
Pomaliza, kapangidwe ka mphika wowonjezera ndi monga malo olumikizirana mapaipi amadzi pamwamba ndi pansi pake. Chitoliro chomwe chili pamwamba pa thanki ndi doko lobwerera, komwe choziziritsira chimabwerera m'mphika; Pansi pa thanki pali malo otulutsira madzi, omwe amatsogolera mwachindunji ku pampu ya injini, ndikudzazanso pampu ndi antifreeze. Palinso chizindikiro chowonekera bwino pa ketulo chomwe chikuwonetsa malire apamwamba ndi otsika a choziziritsira.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
