Industry in the low speed large capacity centrifuge role

On low speed large capacity centrifuge the other information please visit http://www.shlxj.com.cn/ for more details.

According to the structure and industrial centrifuge respectively begged, can be divided into filtering centrifuges, centrifuge and the three class. A centrifuge around the axis high-speed rotating cylinder itself, called the drum, usually driven by an electric motor. Suspension (or emulsion) to participate in the drum after being fast, femoral rotation and drum with speed, under the function of centripetal force components respectively, and were discharged. In general, the higher the role of drum speed, respectively is better. Low speed large capacity centrifuge action principle is centrifugal filter and centrifugal sedimentation two. Centrifugal filtration is the centrifugal pressure makes the suspension in the centripetal force field, role in filter media, so that the liquid through the filter media into the filtrate, and solid particles are trapped in the filter medium surface, and then the end of liquid-solid separation; centrifugal sedimentation is the use of suspension (or emulsion emulsion) each density different points the principle of rapid sedimentation and delamination in the centripetal force field, the end of liquid - solid (or liquid - liquid) separation. There is a class of tests for the analysis of machine can be carried out respectively, liquid clearance and solids concentration, separation or liquid - liquid, this kind of the atmospheric and vacuum, freezing conditions of operation is not the same type of structure.
An important goal of centrifugal machine are respectively weighing function is respectively factor. It shows that the ratio of material by respectively in the drum of the centripetal force and gravity, respectively factor larger, generally were also more rapid, respectively the better. Industrial use of low speed large capacity centrifuge respectively is 100 ~ 20000 factor, speeding tubular respectively machine respectively factor can be as high as 62000, respectively, for speeding analysis machine respectively factor up to 610000. Another factor in the selection of low speed large capacity centrifuge processing ability is the drum work area, large working area disposal can also. Filtering centrifuges and centrifuge, rely mainly on the increase to expand operations in the face of the drum drum diameter on the circumference of the circumferential wall; respectively, except a drum machine, and additional work surface, such as the inner cylinder and disc disc type machine machine respectively respectively, significantly increases the settling work surface.
