As is known to all, over the years, because of the peristaltic pump with its small size, high transmission precision, corrosion resistance, good control advantages, such as design can meet the special requirements of users of all kinds of industry generally, make its application in the pharmaceutical industry is more and more widely.
如我国目前制药行业中用于自动定量加料、配料、灌装或注入各类粘合剂、清洗剂、消毒剂等。这些应用或是由于物料用量较小，须精确控制剂量来确保配比或灌装精度，或是因为物料具有一定的腐蚀性，所用一般的泵很难满足这些用户要求的，大多都采用了蠕动泵。
For example, the pharmaceutical industry in China is used for automatic quantitative loading, filling, filling or injection of various adhesives, cleaning agents, disinfectants, etc. These applications or due to the material consumption is small, must be precisely controlled doses to ensure matching or filling accuracy, or because of material has certain corrosion, commonly used in pump is difficult to meet the user requirements, mostly adopted the peristaltic pump.
小编作为一个在制药行业“摸爬滚打”了几十年的制药人，在实际生产中，不难发现好多使用者对蠕动泵的运行原理及其优缺点不是十分了解，所以在生产应用中不能很好地“用其所长，避其所短”。为此，小编根据自身的学习和理解，搜集整理了这篇《浅谈蠕动泵的机械原理及其优缺点》一文，把它分享给大家，希望赏识者能够喜欢。由于小编知识水平有限，不对之处，欢迎各位大侠拍砖评判！
Small make up in the pharmaceutical industry as a "seasoning" decades of pharmaceuticals, in actual production, it is not difficult to find a lot of users running principle and its advantages and disadvantages of peristaltic pump is not very understanding, so can't very well in the production practice "his element working on the, avoid the short. Therefore, small make up according to their own learning and understanding, collect the article introduction to the mechanical principle of peristaltic pump and its advantages and disadvantages, share it to all of you, hope the recognition to like it. Due to our limited knowledge, we welcome you to make bricks!
那么我们先来说说什么叫蠕动泵？它是如何运行的？其实，蠕动泵也叫恒流泵或软管泵，其机械运行原理十分简单。因为它的运行方式是通过对泵管进行交替重复的机械挤压和释放来泵送流体的。之所以叫蠕动泵，也是因为其泵管的运动方式就象一条蠕动的虫子一样移动，蠕动泵就是将软管装卡在机械转子和定子之间，以此达到泵送流体的目的。（见图1）蠕动泵工作时，在两个滚轮之间的一段泵管会形成泵室，泵室的大小取决于泵管的内径和转子的尺寸（见图2、图3、图4）。蠕动泵的理论流量为泵室的容积，拿回转直径相同的泵相比较，产生较大泵室的泵，其转子每转一圈所输送的流体容积也较大，但产生的脉冲也较大。相反，产生较小泵室的泵，其转子每转一圈所输送的流体容积也较小，但产生的脉冲也较小，但快速、连续的泵送可以非常理想地降低脉冲，因此，在一些小流量、要求非常小的脉冲场合，泵头的选择就显得非常关键。
So let's start with what is the peristaltic pump? How does it work? In fact, peristaltic pump is also called constant current pump or hose pump, its mechanical operation principle is very simple. Because the way it works is to pump fluid through a mechanical squeeze and release of the pump tube. Called peristaltic pump, but also for its means of the movement of the pump pipe like a squirmy worm, peristaltic pump is install hose card between the mechanical rotor and stator, in order to achieve the goal of pumping fluid. (see figure 1) peristaltic pump, a pump pipe between two roller will form the pump room, pump room depends on the size of the pump pipe diameter and the size of the rotor (see figure 2, figure 3, figure 4). Peristaltic pump flow of theory for the pump chamber volume, compared with turning diameter of the same pump, large pump of pump chamber, the rotor per round the transmission fluid volume is bigger also, but the pulse is bigger also. Instead, produce smaller pump of pump chamber, the rotor per round the transmission fluid volume is smaller, but the pulse is smaller, but the rapid and continuous pumping to reduce pulse can be very ideal, therefore, on a little traffic, requires very little pulse, the choice of pump head is very critical.
