Description

一种旋转式流体计量方法及旋转式流体计量装置 【技术领域】
本发明主要涉及到流体计量技术领域，特指一种适用于流体的旋转式流体计量方法及旋转式流体计量装置。
【背景技术】
随着技术的发展，很多特殊行业对计量的精度及洁净度的要求越来越高，比如生物制药行业、医疗行业、化工行业等。目前，在对流体进行精确计量时，一般采用柱塞泵、蠕动泵技术。但是现有方式仍然存在一些不足，从而大大影响到计量的精确性。现有不足就在于：
1.现有的柱塞泵在工作时与流体有直接接触，同时柱塞会与泵体之间存在摩擦，这就容易将产生的微粒混入到流体当中，且清洗不方便。
2.现有的蠕动泵虽然能很好的解决卫生问题，但由于旋转蠕动泵的计量总量是依靠滚子多圈滚动完成，计量精度较差，一般在2％左右。同时，滚子不停的在弹性软管上滚动，对软管的损伤较大。而现有直线蠕动泵精度较高，但采用直线式往复动作，压软管推进的滚子在每一个工作循环中均需要动力提升和下降，使得整个上升和下降的动力都需要跟着做往复运动，因而结构复杂，稳定性差。
【发明内容】
本发明要解决的技术问题就在于：针对现有技术存在的技术问题，本发明提供一种原理简单、成本低廉、精度高的旋转式流体计量方法及旋转式流体计量装置。
为解决上述技术问题，本发明采用以下技术方案：

作为本发明方法的进一步改进：所述截止点是通过滚子对弹性软管的挤压来实现。
本发明进一步提供一种旋转式流体计量装置，包括旋转推滚机构、弹性软管和出口压管机构，所述弹性软管内供流体流动，所述弹性软管内的一端为出口，用来排出流体，所述弹性软管内的另一端为进口，用来吸入流体；所述弹性软管沿着圆弧形轨迹布置，所述旋转推滚机构接触弹性软管并沿着弹性软管的布置方向做旋转运动。
作为本发明装置的进一步改进：所述弹性软管安装于固定座上，所述固定座内设有工 作圆弧面。
作为本发明装置的进一步改进：所述弹性软管围绕固定座的工作圆弧面的内侧布置，或者所述弹性软管围绕固定座的工作圆弧面的外侧布置。
作为本发明装置的进一步改进：所述旋转推滚机构包含旋转驱动机构和伸缩推滚机构，所述旋转驱动机构布置在所述弹性软管圆弧形轨迹的中心，所述旋转驱动机构的旋转中心与所述弹性软管圆弧形轨迹的中心线重合。
作为本发明装置的进一步改进：所述伸缩推滚机构包含伸缩摆杆机构和推滚，所述伸缩摆杆机构包括两套且对称安装在旋转驱动机构的旋转驱动轴上，与旋转驱动轴同步旋转，同时两套伸缩摆杆机构进行同步伸缩以压紧和松开弹性软管。
作为本发明装置的进一步改进：所述伸缩推滚机构包含伸缩摆杆机构、推滚和固定摆杆，所述伸缩摆杆机构和固定摆杆对称安装在旋转驱动机构的旋转驱动轴上，与旋转驱动轴同步旋转，所述伸缩摆杆机构和固定摆杆配合以压紧和松开弹性软管。
作为本发明装置的进一步改进：所述出口压管机构包含压管驱动机构、压管杆和压管座，所述弹性软管从压管杆和压管座中间穿过，所述压管驱动机构带动压管杆上下往复运动以压紧和松开弹性软管。
作为本发明装置的进一步改进：所述旋转推滚机构的运动曲线是直线或圆弧。
与现有技术相比，本发明的优点在于：本发明的旋转式流体计量方法及旋转式流体计量装置，原理简单、成本低廉、精度高，滚子一次旋转行程完成整个计量，比现有旋转蠕动泵计量精度高；采用旋转式绕管，与现有直线式蠕动泵相比，大大节约了空间，简化了结构。且滚子无需升降，结构更加简单，稳定性好。相对于弹性软管来说，相对静止或只有非常微小的位移量，对弹性软管的损伤小。
