M'zaka zaposachedwapa, takhala tikuyang'ana kwambiri pakupanga zida zoteteza chilengedwe. Kudziwa za kuteteza chilengedwe kudzakhalanso chinthu chofunikira kwambiri. Mu njira yopitira patsogolo ya zida zoteteza chilengedwe, zida zopangira ma Cold roll mosakayikira ndizofala kwambiri pamsika wonse, komanso kulimbikitsa chitukuko cha zida zoteteza chilengedwe. Chifukwa chake, cholinga chachikulu cha chitukukochi chikadali pa zofunikira pakugwiritsa ntchito. Ndipo palibe kukayika kuti chinthu chimodzi chiyenera kukhala ndi ntchito zosiyanasiyana.
Kugwiritsa ntchito makina ozizira opangira ma roll
1. Musanayambe ntchito, yang'anani magetsi, pampu yamafuta a mota, choyezera kuthamanga, mtengo wochepetsera, mtengo wamagetsi, ndi chosinthira cha makina opangira ma roll ozizira kuti muwone ngati ndi abwinobwino komanso ngati pali vuto lililonse. Ngati lilipo, liyenera kuthetsedwa kuti makinawo agwire ntchito bwino.
2. Kokani injini, makamaka kuti muwone ngati ikuzungulira molondola.
3. Pambuyo poti kuwunika konse kwachitika, mota ikhoza kuyatsidwa, kenako kuthamanga kwa mafuta kumasinthidwa kukhala 10MPa, ndipo kuthamanga kwa mayeso kumatha pafupifupi mphindi zitatu. Ngati izi sizili zovuta, ndiye kuti mutha kuyamba kugwira ntchito mwalamulo.
4. Zipangizo za makina opangira makina ozizira ziyenera kuyikidwa pa maziko olimba komanso olimba, ndipo ziyenera kukhala zathyathyathya.
5. Musanagwiritse ntchito, onjezani mafuta ndi mafuta a hydraulic ndipo muzisinthe nthawi zonse.
Ndi zaka zoposa 20 zakuchitikira komanso kukhutira kwenikweni ndi makasitomala, mutha kudalira ife pa ntchito zanu zotsatira. Tikhoza kupereka ntchito zaukadaulo zopangira, kupanga, ndi kupereka magawo, ndikusamalira moona mtima kukhutitsidwa kwa makasitomala.
udindo wazachuma kwa makasitomala athu
khalidwe labwino kwambiri komanso luso
ubwino ndi kufunika kwa polojekiti yathu
miyezo yapamwamba kwambiri yowongolera mtengo
pa nthawi yake komanso pa bajeti
kuyang'ana kwenikweni pa kukhutitsidwa kwa makasitomala
