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.
如我國目前制藥行業(yè)中用于自動(dòng)定量加料、配料、灌裝或注入各類粘合劑、清洗劑、消毒劑等。這些應(yīng)用或是由于物料用量較小，須精確控制劑量來確保配比或灌裝精度，或是因?yàn)槲锪暇哂幸欢ǖ母g性，所用一般的泵很難滿足這些用戶要求的，大多都采用了蠕動(dòng)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.
小編作為一個(gè)在制藥行業(yè)“摸爬滾打”了幾十年的制藥人，在實(shí)際生產(chǎn)中，不難發(fā)現(xiàn)好多使用者對蠕動(dòng)泵的運(yùn)行原理及其優(yōu)缺點(diǎn)不是十分了解，所以在生產(chǎn)應(yīng)用中不能很好地“用其所長，避其所短”。為此，小編根據(jù)自身的學(xué)習(xí)和理解，搜集整理了這篇《淺談蠕動(dòng)泵的機(jī)械原理及其優(yōu)缺點(diǎn)》一文，把它分享給大家，希望賞識(shí)者能夠喜歡。由于小編知識(shí)水平有限，不對之處，歡迎各位大俠拍磚評判！
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!
那么我們先來說說什么叫蠕動(dòng)泵？它是如何運(yùn)行的？其實(shí)，蠕動(dòng)泵也叫恒流泵或軟管泵，其機(jī)械運(yùn)行原理十分簡單。因?yàn)樗倪\(yùn)行方式是通過對泵管進(jìn)行交替重復(fù)的機(jī)械擠壓和釋放來泵送流體的。之所以叫蠕動(dòng)泵，也是因?yàn)槠浔霉艿倪\(yùn)動(dòng)方式就象一條蠕動(dòng)的蟲子一樣移動(dòng)，蠕動(dòng)泵就是將軟管裝卡在機(jī)械轉(zhuǎn)子和定子之間，以此達(dá)到泵送流體的目的。（見圖1）蠕動(dòng)泵工作時(shí)，在兩個(gè)滾輪之間的一段泵管會(huì)形成泵室，泵室的大小取決于泵管的內(nèi)徑和轉(zhuǎn)子的尺寸（見圖2、圖3、圖4）。蠕動(dòng)泵的理論流量為泵室的容積，拿回轉(zhuǎn)直徑相同的泵相比較，產(chǎn)生較大泵室的泵，其轉(zhuǎn)子每轉(zhuǎn)一圈所輸送的流體容積也較大，但產(chǎn)生的脈沖也較大。相反，產(chǎn)生較小泵室的泵，其轉(zhuǎn)子每轉(zhuǎn)一圈所輸送的流體容積也較小，但產(chǎn)生的脈沖也較小，但快速、連續(xù)的泵送可以非常理想地降低脈沖，因此，在一些小流量、要求非常小的脈沖場合，泵頭的選擇就顯得非常關(guān)鍵。
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.
