摘要

　  离心分离器又称离心机。利用离心力将溶液中密度不同的成分进行分离的一种设备。

　　可进行固液分离、液液分离(重液体和轻液体及乳浊液等)。该设备的主要部分是电机带动一可旋转的圆筒，称做转鼓。有的转鼓壁上有很多小孔，离心分离时，转鼓壁上衬有滤布，使固体物留在鼓壁而液体通过小孔甩出。也有的转鼓无小孔，被甩液体可以用导管排出。

　　离心机的转速可分为常速和高速，离心机的转速越高，分离效果越好(实际应该是看离心力，离心力越大分离效果越好，但是离心力的大小与转速的平方成正比，所以也可认为转速越高分离效果越好）。

按分离的机理来说，离心机可分为过滤离心机和沉降离心机。按主轴和转鼓轴线的方向可分为立式和卧式。按离心机操作特征可分为间歇式和连续式。按卸料方式分为推料式、刮刀式和螺旋式等。

Abstract

Centrifugal separator, also known as centrifuges. The use of centrifugal force in the density of the solution to separate the different components of a device.

Can be solid-liquid separation, liquid-liquid separation (heavy liquid and light liquid and emulsion, etc.). The main part of the device is a motor driven rotating cylinder can be, known as the drum. Some walls have many small drum, centrifugal separation, the drum wall has cloth lining, so that solids remain in the drum wall and releases the liquid through small holes. Drum and some non-small hole catheter can be left discharged liquid.
       Speed centrifuge can be divided into constant speed and high-speed, high speed centrifuge to separate the effect of the better (actually look at the centrifugal force should be, the better the effect of centrifugal force, the greater the separation, but the size of the centrifugal force is proportional to the square of the speed, so can also be separated from the effect that the higher the speed the better).
        According to the mechanism of separation, the centrifuge can be divided into centrifuges and sedimentation centrifuge filter. Spindle and drum in accordance with the direction of the axis can be divided into vertical and horizontal. According to the characteristics of centrifuge operation can be divided into intermittent and continuous. By way of discharging material into push-type, and spiral scraper, etc..
