Pomanga misewu yayikulu, makina opangira misewu nthawi zambiri amayambitsa mavuto ambiri chifukwa chosagwiritsidwa ntchito moyenera, choncho kupita patsogolo kwa ntchitoyo kuyenera kuyimitsidwa, zomwe zimakhudza kwambiri kumaliza ntchito yomangayo. Mwachitsanzo, vuto la valavu yobwerera kumbuyo kwa chosakaniza cha asphalt.
Zolakwika za valve yobwerera kumbuyo kwa chosakaniza cha asphalt mumakina omanga misewu sizovuta. Zodziwika bwino ndikubwerera mosayembekezereka, kutayikira kwa gasi, kulephera kwa ma valve oyendetsa ma elekitiroma, ndi zina zotere. Zomwe zimayambitsa ndi zothetsera ndizosiyana. Kuti valavu yosinthira zisasinthe nthawi yake, nthawi zambiri imayamba chifukwa chamafuta otsika, kasupe amakakamira kapena kuwonongeka, dothi lamafuta kapena zonyansa zimakakamira pagawo lotsetsereka, ndi zina. Pachifukwa ichi, ndikofunikira kuyang'ana momwe lubricator ndi ubwino wa mafuta opaka. Viscosity, ngati kuli kofunikira, mafuta odzola kapena mbali zina zitha kusinthidwa.
Pambuyo pakugwiritsa ntchito kwa nthawi yayitali, valavu yobwezeretsayo imakhala yosavuta kuvala mphete yosindikizira ya valve, kuwonongeka kwa tsinde la valve ndi mpando wa valve, zomwe zimapangitsa kuti mpweya uwonongeke mu valve. Panthawiyi, mphete yosindikizira, tsinde la valve ndi mpando wa valve ziyenera kusinthidwa, kapena valavu yobwerera iyenera kusinthidwa mwachindunji. Pofuna kuchepetsa kulephera kwa zosakaniza za asphalt, kukonza kuyenera kulimbikitsidwa tsiku ndi tsiku.
Makina omanga misewu akawonongeka, amatha kusokoneza ntchitoyo mosavuta, kapenanso kuyimitsa kupita patsogolo kwa ntchitoyo pakachitika zovuta. Komabe, chifukwa cha chikoka cha ntchito ndi zinthu zachilengedwe, zida zosakanikirana ndi phula zidzawonongeka panthawi yogwira ntchito. Kuti tichepetse kutayika komanso kukulitsa moyo wautumiki wa zida, tiyenera kuchita ntchito yabwino yosamalira.
Yang'anani ngati mabawuti a mota yogwedezeka ali omasuka; fufuzani ngati mabawuti a chigawo chilichonse cha batching station ndi omasuka; fufuzani ngati wodzigudubuza aliyense akukakamira/osazungulira; fufuzani ngati lamba wapotoka; yang'anani kuchuluka kwa mafuta ndi kutayikira, ndikusintha chisindikizo chowonongeka ngati kuli kofunikira ndikuwonjezera mafuta; kuyeretsa mabowo mpweya wabwino; kupaka mafuta pa lamba conveyor tensioning screw.
Onani ngati mabawuti a chigawo chilichonse cha otolera fumbi ndi otayirira; fufuzani ngati silinda iliyonse imagwira ntchito bwino; fufuzani ngati silinda iliyonse imagwira ntchito bwino komanso ngati pali kutayikira munjira iliyonse ya mpweya; yang'anani ngati pali phokoso lachilendo mu fan fan, ngati lambayo ndi yolimba moyenerera, komanso ngati chowongolera chowongolera chimakhala chosinthika. Makinawa amatha kuzimitsidwa nthawi zonse pogwira ntchito kuti achepetse kutayika kwa chinsalu chogwedezeka.
