Kodi kunyamula mantha kwambiri ndi ntchito bwanji?
Kutaya Matumba amagwiritsidwa ntchito kuponderezanso chiwopsezo cha kasupe pomwe amachira chifukwa cha kuchepa kwa nkhawa komanso kugwedezeka kuchokera pamsewu. Amagwiritsidwa ntchito kwambiri pagalimoto kuti athandizire kugwedeza kwa chimango ndi thupi ndikusintha chitonthozo chagalimoto. Pambuyo pamsewu wopanda msewu, ngakhale kuti kuvota kasupe katha kuseka mseu, kasupe weniweniwo udzakhalanso ndi zoyenda, ndipo kunyamula kwagwedeza kumalepheretsa kudumphadumpha.
Pofuna kukonza zotonthoza mgalimoto pamene chinthu chotakata chikuwoneka bwino, chambiri cha elastic chowoneka chimayikidwa mofanana mu kuyimitsidwa kuti mudziwe kugwedezeka. Kutulutsa kwadzidzidzi komwe kumagwiritsidwa ntchito mu njira yoyimitsidwa ndikugwedeza, ndipo mfundo yake yogwira ntchito ndikuti pomwe kugwedezeka kwa mzere kumachitika pakati pa chimango (kapena thupi), pisitoni limasunthika pansi. Mafutawo chifukwa cha kugwedeza m'chipinda chowoneka bwino kuchokera ku chipinda chimodzi kupita kwina kudzera m'ma pores osiyanasiyana. Pakadali pano, mikangano pakati pa khoma la dzenje ndi mafuta ndi mikangano yamkati pakati pa mamolekyulu opangira mafuta, kuti mpweya woponderezedwa wagalimoto umasinthidwa kukhala mphamvu ya mafuta, kenako nkulefulidwa ndi mlengalenga. Pamene gawo la mafuta ndi zinthu zina sizimasinthika, mphamvu yotsika imakwera kapena kuchepetsa liwiro pakati pa chimango ndi shaft (kapena gudumu), lomwe likugwirizana ndi mawonekedwe amafuta.
Kufotokozera kwa mfundo yogwirira ntchito ya masilikiti yochita chidwi: mu complen stroke, zikutanthauza kuti gudumu lagalimoto ili pafupi ndi thupi, kubzala kwamphamvu kumazungulira, ndipo piston mumiyala yomwe imasunthira pansi. Kuchepetsa kwapadera kwa piston kumachepa ndipo kuthamanga kwa mafuta kumawonjezeka. Mafuta amayenda mu valavu yoyenda pamwamba pamwamba pa piston (m'chipinda chapamwamba). Chipinda cham'mwamba chimakhala gawo la malo a piston rod, motero kuchuluka kwa chipinda cham'mwamba ndi chocheperako kuposa kuchuluka kwa chipinda cham'munsi, kenako gawo la mafuta limakankhira chingwe chophatikizira kuti chibwerere ku silinda yosungirako. Chuma chamafuta cha mavuvu awa amapanga gulu la kuyimitsidwa pa nthawi yopanga. Pamene kubzala kwadzidzidzi kumakulitsidwa, gudumu ndikofanana ndi kuchoka m'thupi, ndipo kutywala kumakulitsidwa. Piston ya kukomoka kwamphamvu kumasunthira m'mwamba. Kupanikizika kwamafuta m'chipinda cha piston, valavu yoyenda imatsekedwa, ndipo mafuta m'chipinda cham'mwamba amakankhira valavu yokulitsa m'chipinda chotsika. Chifukwa cha kukhalapo kwa ndodo ya piston, kuchuluka kwa mafuta kutuluka m'chipinda chapamwamba sikokwanira kudzaza kuchuluka kwa chipinda cham'munsi. Cholinga chachikulu ndi chopukutira m'munsi mwapadera. Pakadali pano, mafuta omwe ali pachilonda chosungira amakankhira chitsimikizo vala 7 m'chipinda chotsika kuti chilemekezedwe. Chifukwa cha zomwe zimachitika bwino kwambiri mwa mavuvuwa, kuyimitsidwa kumachitika ngati chopota pakuyenda.
