Uyini umehluko phakathi komnyango oseduze nesiphethu saphansi?
Ihadiwe yokulawula umnyango iyithuluzi lomkhiqizo elisekela elibaluleke kakhulu ekuphileni kwansuku zonke kwabantu.Ihlanganisa ikakhulukazi: iziphethu zaphansi nezivalo zeminyango, ezivame ukusetshenziswa ezitolo ezinkulu, izakhiwo zamahhovisi, izindawo zokuhlala, amahhotela nezinye izindawo zomphakathi.Umsebenzi oyinhloko ukuqinisekisa ukuthi umnyango ungavulwa ngokujwayelekile, noma umnyango ungavalwa endaweni yokuqala ngokunembile nangesikhathi.Ngokuvamile, izivalo zeminyango zinomsebenzi wokuvala umnyango ngokuzenzakalelayo.Umnyango oseduze ungavala umnyango ohlangothini olulodwa kuphela, kuyilapho umnyango olawulwa isiphethu ophansi ungavala umnyango nhlangothi zombili.
Umnyombo wombono womklamo oseduze womnyango uwukubona ukulawulwa kwenqubo yokuvala umnyango, ukuze izinkomba ezihlukahlukene zokusebenza zenqubo yokuvala umnyango zingalungiswa ngokuvumelana nezidingo zabantu.Ukubaluleka komnyango oseduze akukhona nje ukuvala umnyango ngokuzenzakalelayo, kodwa futhi ukuvikela uhlaka lomnyango kanye nomzimba womnyango.Okubaluleke nakakhulu, izivalo zeminyango seziyingxenye ebalulekile yokuphatha okuhlakaniphile kwezakhiwo zesimanje.
Iziphethu zaphansi zithathwa njengezivalo zeminyango enamanzi, kodwa isisetshenziswa esisetshenziswa ukucindezela iziphethu igiya lezikelemu esikhundleni serack.Ukucushwa okuyisisekelo kwentwasahlobo yaphansi yi-eksisi engenhla ne-axis eya phansi.I-aerial axis iyisesekeli esixhuma uhlaka lomnyango kanye neqabunga lomnyango engxenyeni engenhla.Iqukethe i-bolt-type shaft egxilwe eqabungeni lesicabha kanye nesihlahla esigxilwe eqabungeni lomnyango.Iziphethu zaphansi zihlukahlukene futhi zifanele cishe zonke izinkuni, insimbi, iminyango ye-aluminium alloy kanye neminyango yengilazi engenafreyimu.
