Working Principle of Peristaltic Pump
The peristaltic pump is like squeezing a flexible pipe filled with fluid
with a finger, and moving the fluid forward along the sliding pipe with
the finger. Peristaltic pumps are also based on the principle that the
wheel replaces the finger. The fluid is pumped by alternating extrusion
and release of the flexible conveying hose of the pump. Like squeezing a
hose with two fingers, as the fingers move, a negative pressure is
formed in the hose and the liquid flows along with it.
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JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 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）。
Peristaltic pump is a kind of "pillow" fluid formed in a section of pump
pipe between two rollers. The volume of the "pillow" depends on the
inner diameter of the pump pipe and the geometric characteristics of the
rotor. The flow rate depends on the product of the rotational speed of
the pump head and the size of the "pillow" and the number of "pillows"
produced by the rotor in each turn. The size of "pillow" is usually
constant (except when pumping fluid with extra viscous fluid).
