Kusankha mafuta mowers udzu

Chilimwe chilichonse, nyengo ya yogwira luso ntchito mafuta. Ngakhale mu dziko lathu, mowers udzu akhala akugwiritsidwa ntchito mwakhama M'zaka zaposachedwapa, makamaka kudziwika kwa ife yekha kwa mafilimu TV.

N'zoona kuti ogwiritsa zipangizo ngati pali mavuto ambiri, monga zinachitikira ntchito yake alibe onse. Makamaka, makamaka mutu amachititsa mafuta mowers udzu, kusankha omwe si mophweka. Mwa njira, zingakhale mwa malo amenewa, kunena kuti ogula ambiri anadziwotcha ukasintha cholakwika i lubricant kusankha, monga aukira wa ntchito zoyambirira za luso ntchito.

Nthawi zambiri, iwo amayiwala kuti ngakhale mafuta a lawnmowers kusankha poganizira kutentha ndi zizindikiro zachilengedwe.

Amadziwika kuti lubricant kulikonse kwa injini anayi sitiroko ayenera kukumana ena ntchito SAE kukhuthala. Kumene, udzu udzu pa otsika kutentha yozungulira limakula bwino kwambiri, kotero kuti pamene inu kugula muyenera kuganizira zinthu, amene chithunzi mu chizindikiro ichi limafanana ndi zaka ntchito.

Ambiri mwa opanga ananena kuti zabwino adzakhala mafuta lawnmowers, yoyenera SAE 30. ntchito mitundu zochepa viscous kwa nyengo yozizira ndi mafuta kwambiri chifukwa madera otentha nawonso saloledwa. Chifukwa chiyani?

Mfundo za kamangidwe ka zipangizozi. Kuchepetsa ndalama ndi zinthu zochepa kupanga okonza awo kwathetsa mpope mafuta zikuchokera awo. Chifukwa, kondomu zigawo zonse yoyamikira injini ikuchitika kudzera crankshaft ndi, imene kayendedwe ake "kutapira" izo kuchokera crankcase ndi, wogawana amagawa lubricant ndi mikangano m'madera onse. Ndicho chifukwa mafuta mowers mafuta udzu simungathe kugula mu sitolo choyamba, monga mukhoza ina kuti "wodala ndi" nkhani kwa kukonza ake.

Choncho, pamene kwambiri madzi kugwirizana lubricating zikuchokera yotsiriza chabe adzingotaikira kumbuyo kwa crankshaft mu crankcase lapansi. Ngati wandiweyani kwambiri, ndiye thunthu mwina patapita nthawi kutembenukira mu misa amorphous olimba, zomwe si m'njira iliyonse.

Cars komanso bwino kutetezedwa ku mavuto amenewo, monga kwa pachilichonse olimbana kondomu kumeneko limafanana wapadera mpope mafuta. Theoretically, onse a mafuta mowers udzu angagwiritsidwe ntchito magalimoto, koma mankhwala muyezo makina si nthawi zonse woyenera zina magalimoto.

Mwamwayi, pafupifupi onse apadera unyolo ritelo zogulitsa wa kondomu mafuta kalasi SAE 30. Zimenezo zokha malo ogulitsira ngati alibe m'mizinda yonse, osanenapo m'matauni ang'onoang'ono. Choncho wotani mafuta kutsanulira mu makina otchetchera kapinga, pakalibe options enieni?

Akatswiri amanena kuti chifukwa cha ichi yabwino yoti lubricant kalasi SAE 15W-40 ndi SAE 20W 50. Ndipo kugula "kupanga" kapena mafuta mchere zilibe kanthu, monga mower ukadali si ntchito zinthu mofanana zovuta, zimene ziyenera kumakwera anagona galimoto.
