水环式真空泵分子式：CAS号：性质：转子在泵内旋转时形成水环的真空泵。泵体是圆筒形，中有偏心装置的转子，转子上有叶板。开动前，泵内充入一定高度的水(或其他液体)。当转子旋转时，水被搅动而旋转并产生离心力，沿泵体形成一定厚度的水环。由于转子的旋转，轴中心不与泵体的中心重合而水环的圆心也不与转子的中心重合。这样，插入水环中的叶板间就形成了水室逐渐增大，可将外部气体通过吸入孔隙而吸人小室内。在旋转的后一半，小室逐渐减小，使气体压缩而从排出孔隙排出。转子不断地旋转，就可将气体不断地吸人和排出。属于湿式真空泵，最高真空度可达85％。构造简单紧凑，没有阀等机件，很少堵塞。也可用于输送气体，但不宜用于含有固体颗粒的气体。
