蠕动泵通过对泵的弹性输送软管交替进行挤压和释放来泵送流体。就象用两根手指夹挤软管一样,随着手指的移动,管内形成负压,液体随之流动.蠕动泵就是在两个转辊子之间的一段泵管形成“枕”形流体。“枕”的体积取决于泵管的内径和转子的几何特征。流量取决于泵头的转速与“枕”的尺寸、转子每转一圈产生的“枕”的个数这三项参数之乘积。“枕”的尺寸一般为常量（泵送粘性特别大的流体时除外）。拿转子直径相同的泵相比较，产生较大“枕”体积的泵，其转子每转一圈所输送的流体体积也较大，但产生的脉动度也较大。这与膜阀的情形相似。而产生较小“枕”体积的泵，其转子每转一圈所输送的流体体积也较小；而且，快速、连续地形成的小“枕”使流体的流动较为平稳。这与齿轮泵的情形相似。 The squirm pump compresses and releases the pump through a flexible conveyor hose. Like use two fingers to squeeze the hose, along with the movement of the fingers, tube forming negative pressure, the liquid flow. Peristaltic pump is between two turning rolls a form "pillow" form fluid pump pipe. The size of the pillow depends on the internal diameter and the geometry of the rotor. The flow rate depends on the number of "pillow" the number of the "pillow" of the pump head and the "pillow" of the rotor. The size of the "pillow" is usually constant (except when the pump delivers a particularly viscous fluid). With rotor diameter, in comparison with the same pump "pillow" larger volume pump, its rotor per round the transmission fluid volume is bigger also, but the pulse is bigger also. This is similar to the membrane valve. The volume of the pump that produces a smaller "pillow" is smaller than that of the rotor. Furthermore, the rapid and continuous formation of small "pillows" makes the fluid flow more smoothly. This is similar to the case of a gear pump. 具有双向同等流量输送能力；无液体空运转情况下不会对泵的任何部件造成损害；能产生达98%的真空度；没有阀、机械密封和填料密封装置，也就没有这些产生泄露和维护的因素；能轻松的输送固、液或气液混合相流体，允许流体内所含固体直径达到管状元件内径40%；可输送各种具有研磨、腐蚀、氧敏感特性的物料及各种食品等；仅软管为需要替换的部件，更换操作极为简单；除软管外，所输送产品不与任何部件接触。 Having the capacity of two-way traffic; There is no damage to any part of the pump in the absence of a liquid air. It produces 98 percent vacuum; There are no valves, mechanical seals, and packing seals, and there is no such thing as leakage and maintenance; It is easy to transport solid, liquid or gas-liquid mixtures, allowing the solid diameter of the fluid to reach 40% of the diameter of the tube. It can carry all kinds of materials, such as abrasive, corrosive, oxygen-sensitive properties and various kinds of food. The hose is a simple replacement for the parts that need to be replaced. The product is not in contact with any part except the hose.
