Machubu Opanda Msoko / chubu chokonzeka kukonzedwa
Chiyambi cha Zamalonda
Machubu oyeretsedwa nthawi zambiri amapangidwa ndi chitsulo champhamvu kwambiri kapena chitsulo chosapanga dzimbiri, kuphatikizapo C20 CK45 E355 (ST52) SAE1026 4140 STKM13C chitsulo chosapanga dzimbiri 316, chitsulo chosapanga dzimbiri 304. Machubu oyeretsedwa amachitidwa njira yoyeretsedwa mosamala kuti akwaniritse bwino mawonekedwe ake komanso kukula kwake kolondola. Pamwamba pa chubu choyeretsedwacho pamakhala poyera bwino kuti pistoni ya silinda ya hydraulic iyende bwino mkati mwa chubu ndikuchepetsa kutayika kwa kukangana ndi kutuluka kwa madzi.
Chimodzi mwazinthu zazikulu za machubu athu oyeretsedwa ndi kulunjika kwawo bwino komanso kuzungulira, zomwe ndizofunikira kwambiri kuti ma silinda a hydraulic agwire ntchito moyenera. Poganizira kwambiri za uinjiniya wolondola, timapanga machubu oyeretsedwa omwe amapereka magwiridwe antchito okhazikika, magwiridwe antchito osalala komanso moyo wautali wautumiki. Kaya mukufuna machubu oyeretsedwa a makina atsopano a hydraulic kapena zida zina, mutha kudalira zinthu zathu za chubu choyeretsedwa kuti zipereke magwiridwe antchito komanso kudalirika komwe mukufuna.
Kuwonjezera pa machubu okhazikika oyeretsedwa, timaperekanso machubu okonzeka kuyeretsedwa omwe ali ndi machubu oyeretsedwa kale kuti azitha kupirira bwino, zomwe zimakupulumutsirani nthawi ndi khama panthawi yokonza. Machubu athu oyeretsedwa amapangidwa kuti atsimikizire kuti pamwamba pake pakhale bwino kuti pakhale kuphatikizana bwino ndi makina anu a hydraulic.
Ntchito Zogwirizana ndi Makonda
JINYO ndi malo opangira zinthu apamwamba ndipo timagwiritsa ntchito ukadaulo wapamwamba wopanga zinthu komanso njira zowongolera khalidwe kuti tiwonetsetse kuti chubu chilichonse chokongoletsedwa chikukwaniritsa miyezo yathu yokhwima yaubwino. Kuyambira kusankha zinthu mpaka kuwunika komaliza, tadzipereka kupereka machubu okongoletsedwa omwe nthawi zonse amaposa zomwe makasitomala athu amayembekezera.
JINYO ili ndi zomangamanga zonse komanso gulu laukadaulo, ndipo kuwonjezera pa kupereka machubu oyeretsera kukula koyenera, ingathenso Sinthani machubu oyeretsera. Ntchito zathu zomwe timazipanga zimaphimba mbali zonse kuyambira pakupanga, kupanga mpaka kukonza zinthu, ndipo timatha kupereka mayankho omwe makasitomala amafuna. Mwachidule, machubu athu opukutidwa ndi abwino kwambiri pakugwiritsa ntchito ma silinda a hydraulic ndipo tadzipereka kupatsa makasitomala zida zodziwika bwino komanso zodalirika kwambiri za makina a hydraulic.
