Unhappy 水泵

  水泵有很多种。从原理上可以分为气压泵,离心泵,轴流泵,混流泵,螺旋泵等。使用最多的是离心泵。   气压泵是靠大气压力提升水位的。凭借活塞的运动,制造出一个近似真空,外部大气压将水压上来。这种泵因为依 赖与大气压,所以提升水的高度有限。  离心泵的原理是离心现象。是依靠叶轮叶片的转动产生离心作用,将液 体甩出。所以,其输送效果依赖于叶轮的转速,直径等因素。  水泵的分类不能将其工作原理和用途综合化分类 ,那样将会很乱。用途是用途,原理是原理,不同原理的泵可以用在同样的用途。同一种泵同样可以用于不同场合 ,可以用于不同用途。 比如:混流泵就是斜流泵,其采用混流式叶轮,即液体流出叶轮的方向倾斜于轴线。 轴流式泵其液体流出方向平行于轴线。 其分类主要有化工泵 磁力泵 离心泵 排污泵 自吸泵 油泵 水泵厂 上海水泵厂 离心泵厂家 隔膜泵 螺杆泵 齿轮油泵 屏蔽泵 潜水泵 齿轮泵 管道泵 耐腐蚀泵 耐酸泵 多级泵 不锈钢泵 液下泵等等
