Zisindikizo zamakina, zomwe zimagwiritsidwa ntchito nthawi zambiri m'makina osiyanasiyana opopera, zimathandiza kwambiri popewa kutuluka kwa madzi ndikusunga magwiridwe antchito a makinawo. Funso lomwe limabuka nthawi zambiri ndi lofunika kwambiri pakufunika kwa madzi otsekeredwa m'zisindikizo zamakinazi. Nkhaniyi ikuyang'ana kwambiri nkhaniyi yosangalatsayi, pofufuza momwe madzi otsekeredwa mkati mwa zisindikizo zamakina ndikuwona ngati ndi chofunikira kwambiri kuti zigwire bwino ntchito. Yendani nafe pamene tikusankha makina ovuta awa ndi ubale wake ndi madzi otsekeredwa, kupereka chidziwitso kwa mainjiniya ndi anthu omwe amakonda zinthu zosiyanasiyana.
Kodi Madzi a Chisindikizo ndi chiyani?
Madzi otsekereza, omwe nthawi zambiri amadziwika kuti chotchinga kapena madzi otsukira, ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito pogwira ntchito zosiyanasiyana za zisindikizo zamakina. Zisindikizo zamakina ndizofunikira kwambiri popewa kutuluka kwa madzi m'zida zozungulira monga mapampu ndi ma compressor. Madzi otsekereza amagwira ntchito zingapo - amapaka mafuta zisindikizo, amachotsa kutentha komwe kumachitika panthawi yogwira ntchito, komanso amathandiza kusunga kutentha koyenera.
Mwachidule, chisindikizo cha makina ndi chipangizo cholondola kwambiri chomwe chimapangidwa kuti chigwirizane ndi mphamvu zovuta. Mu ntchito yolinganiza bwino iyi, madzi otsekereza amachita ntchito ziwiri zofunika: mafuta ndi choziziritsira. Monga mafuta, zimathandiza kuchepetsa kukhudzana mwachindunji pakati pa malo otsekereza, motero amachepetsa kuwonongeka ndi kutalikitsa moyo wawo. Monga choziziritsira, madzi otsekereza amachotsa kutentha kwambiri kuchokera ku mawonekedwe otsekereza kuti asatenthe kwambiri komwe kungayambitse kulephera kwakukulu.
Cholinga cha Madzi Otsekeredwa
Madzi otsekereza, omwe amadziwikanso kuti madzi otchinga, amachita gawo lofunika kwambiri pakugwira ntchito kwa ma seal amakina. Amagwiritsidwa ntchito makamaka popanga malo abwino kwambiri omwe amatsimikizira kuti ma seal awa amagwira ntchito bwino komanso moyenera. Cholinga chachikulu cha madzi otsekereza ndikupaka mafuta pamwamba pa ma seal, kupewa kukangana ndi kuwonongeka.
