Vavu Special Requirement
Mayeso apadera | Kuzindikira zolakwika zolowa m'zinthu (PT), kuyesa kwa radiator (RT), kuyesa kwamayendedwe, mayeso otsika kutentha. |
Chithandizo chapadera | Chepetsani mankhwala a nayitrogeni, pangani mankhwala a aloyi olimba. |
Kutsuka kwapadera | Degreasing ndi kutaya madzi m'thupi |
Mkhalidwe wapadera | Kupopera kwapadera kapena kugwirizanitsa, chikhalidwe cha vacuum, chomangira cha SS, zokutira zapadera. |
Special dimension | Makonda nkhope ndi nkhope kutalika kapena kukula |
Kuyesa ndi kuyendera | Lipoti la mayeso a chipani chachitatu |
