Chivundikiro cholumikizira chopukutira - shelufu
Makina opukutira ndi chimodzi mwa zida zazikulu zotetezera galimoto. Amatha kuchotsa madontho a mvula ndi chipale chofewa pawindo masiku a chipale chofewa kapena amvula, ndikupukuta madzi amatope omwe amathiridwa pagalasi lakutsogolo poyendetsa pamsewu wamatope, kuti atsimikizire chitetezo cha dalaivala.
Dongosolo lakupukuta lakutsogolo limapangidwa makamaka ndi chotsukira chakutsogolo, njira yolumikizirana ndi chotsukira, chotsukira, pampu yotsukira, thanki yosungira madzi, chitoliro chodzaza madzi, nozzle, chotsukira chakutsogolo, ndi zina zotero; ntchito zazikulu ndi kukwapula kwa sitepe imodzi, kukwapula kosalekeza, kukwapula pang'onopang'ono, kukwapula mwachangu komanso kupopera madzi nthawi imodzi. Dongosolo lakupukuta lakumbuyo limapangidwa ndi makina oyendetsa mota, mota yakumbuyo yotsukira, nozzle, pampu yotsukira, pampu yosungira madzi, thanki yosungira madzi, chitoliro chodzaza madzi, ndi chotsukira (kuphatikiza pampu yotsukira, thanki yosungira madzi, pampu yodzaza madzi ndi chotsukira chakutsogolo). Ndi zofanana) ndi zigawo zina, ntchito zazikulu ndi kukwapula kosalekeza komanso kupopera madzi nthawi imodzi ndi kukwapula.
Zotsukira mpweya ndi mawindo ziyenera kukwaniritsa zofunikira izi: kuchotsa madzi ndi chipale chofewa; kuchotsa dothi; zimatha kugwira ntchito kutentha kwambiri (madigiri 80 Celsius) ndi kutentha kochepa (osachepera madigiri 30 Celsius); zimatha kukana asidi, alkali, mchere ndi ozoni; zofunikira pafupipafupi: ziyenera kukhala ziwiri Kupitirira liwiro limodzi, limodzi ndi lalikulu kuposa nthawi 45/mphindi, ndipo linalo ndi nthawi 10 mpaka 55/mphindi. Ndipo ndikofunikira kuti kusiyana pakati pa liwiro lalikulu ndi liwiro lochepa kukhale kwakukulu kuposa nthawi 15/mphindi; ziyenera kukhala ndi ntchito yoyimitsa yokha; nthawi yogwira ntchito iyenera kukhala yayikulu kuposa ma cycle 1.5 miliyoni; nthawi yokana ma short-circuit ndi yayikulu kuposa mphindi 15.
