    • This invention includes the derivation of the exact mathematical expressions for the curvature, either cardiocle or expanded cardioid, of the casing of the springless eccentric rotor vane pump, thereby facilitating the precision manufacture of the curved surfaces of the casing using CNC techniques. As a result, the capacity and accuracy of the eccentric rotor vane pump is greatly improved. As the section manufacture and assembly of the casing becomes possible, the mass production of large-sized pumps of 1-meter or larger diameter is now attainable, hitherto regarded as almost impossible, and therefore production cost is also reduced. The unique design which positions the axis of eccentricity in the lower central part of the axis of rotor rotation results in increase in the rotation speed of the rotor, and leads to reduction of friction between the vane ends and the curved surface of the casing as the weight of the vane does not affect the movement of the rotor.
    • 本发明包括推导出无弹簧偏心转子叶片泵壳体的曲率(心轴或扩张心形)的精确数学表达式,从而有助于使用CNC技术精确地制造壳体的曲面。 因此,偏心转子叶片泵的容量和精度大大提高。 随着套管的制造和组装成为可能,现在可以实现1米或更大直径的大型泵的批量生产,迄今被认为是几乎不可能的,因此也降低了生产成本。 将偏心轴定位在转子轴线的中心部分的独特设计导致转子旋转速度增加,导致叶片端部与壳体曲面之间的摩擦力减小, 叶片的重量不影响转子的运动。
