蠕動(dòng)泵工作原理
Working Principle of Peristaltic Pump
蠕動(dòng)泵就像用手指夾擠一根充滿(mǎn)流體的軟管，隨著手指向前滑動(dòng)管內(nèi)流體向前移動(dòng)。蠕動(dòng)泵也是這個(gè)原理只是由滾輪取代了手指。通過(guò)對(duì)泵的彈性輸送軟管交替進(jìn)行擠壓和釋放來(lái)泵送流體。就像用兩根手指夾擠軟管一樣,隨著手指的移動(dòng),管內(nèi)形成負(fù)壓,液體隨之流動(dòng)。
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.
蠕動(dòng)泵就是在兩個(gè)轉(zhuǎn)輥?zhàn)又g的一段泵管形成“枕”形流體。“枕”的體積取決于泵管的內(nèi)徑和轉(zhuǎn)子的幾何特征。流量取決于泵頭的轉(zhuǎn)速與“枕”的尺寸、轉(zhuǎn)子JDG金屬穿線(xiàn)管 不銹鋼鏈板 隔離墩模具 檢查井鋼模具 流水槽模具 階梯護(hù)坡模具 護(hù)坡磚模具 遮板模具 每轉(zhuǎn)一圈產(chǎn)生的“枕”的個(gè)數(shù)這三項(xiàng)參數(shù)之乘積?！罢怼钡某叽缫话銥槌Ａ浚ū盟驼承蕴貏e大的流體時(shí)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).
