三、原理和特性

Three principles and characteristics of single screw is made according to the operation of tooth displacement principle of work of the new pump, main working parts are eccentric screw (rotor) and fixed bush (stator) due to the special geometry, the two parts respectively form a single seal cavity, medium by axial uniform flow, the internal flow velocity is low, volume is kept constant, the pressure is stable, so that it can't be produce eddy current and agitationEvery level of the pump output pressure 0.6 Mpa, head of 60 m (water), self-priming height is in commonly more than 3 m, because of the stator of a variety of moving materials, so this kind of pump of high viscosity fluid conveying and containing hard suspended particles medium or medium containing fiber transmission, have a general pump is not up to the characteristics of the flow rate is proportional to the speed of transmission way has a direct drive motor and pump axis, or use speed regulating motor reducer motor has generally enclosed, explosion-proof and pump shaft transmission for users to choose and buy 

单螺杆是按运转齿合容积式原理工作的新型泵重，主要工作部件是偏心螺杆（转子）和固定的衬套（定子）。由于该二部件的特殊几何形状，分别形成单独的密封容腔，介质由轴向均匀推行流动，内部流速低，容积保持不变，压力稳定，因而不会产生涡流和搅动。每级泵的输出压力位0.6Mpa，扬程60M（清水），自吸高度一般在3M以上，因定子选用多种前行材料制成，所以这种泵对高粘度流体的输送和含有硬质悬浮颗粒介质或含有纤维介质的输送，有一般泵所不能胜任的特性，其流量与转速成正比。传动方式有电机与泵轴直接传动，或采用调速电机、减速机。电动机有一般封闭式，防爆式与泵轴传动供用户选购。
