三足式离心机的发展 three decanter centrifuges

离心机是利用离心力，分离液体与固体颗粒或液体与液体的混合物中各组分的机械。
离心机主要用于将悬浮液中的固体颗粒与液体分开；或将乳浊液中两种密度不同，又互不相溶的液体分开(例如从牛奶中分离出奶油)；它也可用于排除湿固体中的液体，例如用洗衣机甩干湿衣服；特殊的超速管式分离机还可分离不同密度的气体混合物；利用不同密度或粒度的固体颗粒在液体中沉降速度不同的特点，有的沉降离心机还可对固体颗粒按密度或粒度进行分级。
 离心机大量应用于化工、石油、食品、制药、选矿、煤炭、水处理和船舶等部门。

Centrifuge is the use of centrifugal force, separating liquid and solid particles or liquid mixture with the liquid components of the machinery.
Centrifuge is mainly used for the suspension of solid particles and liquid separately; or emulsion in two different densities, but also separate immiscible liquids (for example, to separate cream from milk); it can also be used to exclude the wet solid in the liquid, such as wet and dry clothes with washing machine dumped; special speed control separator can separate mixtures of gases of different densities; the use of different density or size of the settling velocity of solid particles in liquids of different characteristics, some Centrifuge also on the solid particles by density or particle size classification.
