Masitepe asanu ndi limodzi kuti akuphunzitseni kuti musinthe mosavuta fyuluta ya mpweya wa excavator:

Fyuluta ya mpweya wa excavator ndi imodzi mwazinthu zofunika kwambiri zothandizira injini. Imateteza injini, imasefa tinthu tating'ono ting'onoting'ono mumlengalenga, imapereka mpweya wabwino ku injini, imalepheretsa injini kuvala chifukwa cha fumbi, komanso imapangitsa kuti injiniyo ikhale yodalirika komanso yolimba. Kugonana kumachita mbali yofunika kwambiri.

Chitoliro cholowetsa kapena chosefera chikatsekedwa ndi dothi, zimapangitsa kuti mpweya usalowe mokwanira, zomwe zimapangitsa kuti injini ya dizilo imveke bwino ikathamanga, kugwira ntchito mofooka, kukwera kwa kutentha kwa madzi, komanso mpweya wotuluka wakuda. Ngati gawo la fyuluta ya mpweya silinakhazikitsidwe bwino, mpweya womwe uli ndi zonyansa zambiri sudzadutsa pa fyuluta pamwamba pa fyuluta, koma umalowa mwachindunji mu silinda kuchokera panjira yodutsa.

Pofuna kupewa zomwe zili pamwambazi, fyulutayo iyenera kukhazikitsidwa motsatira malamulo, ndipo zofunikira za tsiku ndi tsiku ziyenera kulimbikitsidwa. Chofukula chikafika nthawi yokonza, nthawi zambiri fyulutayo imasinthidwa ndi maola 500, ndipo fyuluta yabwino imasinthidwa ndi maola 1000. Ndiye funso ndilakuti, ndi njira zotani zosinthira zosefera mpweya?

Khwerero 1: Pamene injini siinayambike, tsegulani khomo lakumbuyo la kabati ndi chivundikiro chomaliza cha chinthu chosefera, chotsani ndi kuyeretsa valavu ya vacuum ya rabara pachivundikiro chapansi cha nyumba ya fyuluta ya mpweya, fufuzani ngati m'mphepete mwake muli valavu kapena ayi, ndikusintha valavu ngati kuli kofunikira. (Dziwani kuti ndikoletsedwa kuchotsa chinthu chosefera mpweya panthawi yomwe injini ikugwira ntchito. Ngati mugwiritsa ntchito mpweya woponderezedwa kuyeretsa sefa, muyenera kuvala magalasi oteteza).

Khwerero 2: Phatikizani chinthu chosefera chakunja ndikuwunika ngati chosefera chawonongeka. Ngati ndi choncho, chonde sinthani munthawi yake. Gwiritsani ntchito mpweya wothamanga kwambiri kuti muyeretse chosefera chakunja kuchokera mkati, kusamala kuti mpweya usapitirire 205 kPa (30 psi). Yatsani mkati mwa fyuluta yakunja ndi kuwala. Ngati pali mabowo ang'onoang'ono kapena zotsalira za woonda pa chinthu choyeretsedwa, chonde sinthani fyulutayo.

Khwerero 3: Phatikizani ndikusintha fyuluta yamkati yamkati. Dziwani kuti fyuluta yamkati ndi gawo lanthawi imodzi, chonde musamatsuke kapena kuyigwiritsanso ntchito.

Khwerero 4: Gwiritsani ntchito chiguduli kuyeretsa fumbi mkati mwa nyumba. Dziwani kuti ndizoletsedwa kugwiritsa ntchito mpweya wothamanga kwambiri poyeretsa.

Khwerero 5: Konzani bwino zosefera zamkati ndi zakunja ndi zotsekera zosefera mpweya, kuonetsetsa kuti mivi pazipewa ndi mmwamba.

Khwerero 6: Fyuluta yakunja iyenera kusinthidwa kamodzi fyuluta yakunja ikatsukidwa ka 6 kapena nthawi yogwira ntchito ikafika maola 2000. Pogwira ntchito m'malo ovuta, kuwongolera kwa fyuluta ya mpweya kuyenera kufupikitsidwa moyenera. Ngati ndi kotheka, zosefera zoyambira mafuta zitha kugwiritsidwa ntchito, ndipo mafuta omwe ali mkati mwazosefera ayenera kusinthidwa maola 250 aliwonse.
