Corrosion is the light of the class factory to use centrifuges to be special attention. Corrosion and other parts of the centrifuge drum will 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, severe corrosion, as well as its less than the thinnest wall of the drum the drum the minimum allowable wall thickness. In particular, some made ​​of cast iron case, the material of uneven thickness, the error up to 8 ~ 30mm, breakdown in the drum shell will be crushed.

 Mid-1996 to 1997 crop sugar factory in Liuzhou area of ​​a single case of an accident took place: 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 workers at the site, 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 of 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.
