One case of corrosion resulting from the rupture of the drum
One case of corrosion resulting from the cause of the breakdown analysis of the drum
Corrosion is the light of the class factory to use centrifuges to be special attention. Corrosion and other components will allow the centrifuge drum wall thinning, lower intensity, causing a rupture accident.
Cause of the accident
Most of chemical products, sugar and molasses sugar are corrosive, the drum under the effect of long-term work in corrosive media, serious corrosion, even at its thinnest wall below the drum the drum the minimum allowable wall thickness. In particular, some made of cast iron case, the material of uneven thickness, the error of 8 ~ 30mm, breakdown in the drum shell will be crushed.
Mid-1996 to 1997 crop of a sugar factory in Liuzhou area occurred a single case of accident: hanging on a sugar centrifugal separators, drum when suddenly broken, debris flying machine, the brick wall labeled as a pit, fortunately there is no hit the field workers, or else.
After analysis of the centrifuge and found the drum breaks in the wall has been thinned due to corrosion of molasses only 1lmm (new machine drum wall thickness 16mm, the machine has been used ninth crop). This wall thickness can maintain the safe operation of it? Can check the conditions of the centrifuge drum strength.
