1.壓力局限: 用(yòng)柔性管，會(huì)使承受壓力受到(dào)限制(zhì).2.泵在運作(zuò)時(shí)會(huì)産生(shēn→g)一(yī)個(gè)脈沖流,

蠕動泵局限性
Limitations of Peristaltic Pump
1.壓力局限: 用(yòng)柔性管，會(huì)使承受壓力受到(dào)限制(zhì).
1. Pressure Limitation: The use of flexible pipes will limit the pressure to w↑ithstand.
2.泵在運作(zuò)時(shí)會(huì)産生(shēng)一(yī)個(gè)脈沖流,
2. Pump produces a pulse flow during operation.
解決方法是(shì):
The solution is:
①增加滾輪數(shù)量，流量會(huì)降低(dī)
Increasing the number of rollers will reduce the flow rate.
②使用(yòng)脈沖抑制(zhì)器(qì):脈沖抑制(zhì)器(qì)是(shì)一(yī)個(gè)簡單的(de)定位容器(qì)，工(gōng)作(zuò)原理(lǐ)是(shì)由于空(>kōng)氣比液體(tǐ)更具有(yǒu)可(kě)壓縮性，脈沖流進入容器(qì)、液體(tǐ)上(shàng)的(de)氣袋下(βxià)陷吸收脈沖進而平緩的(de)流出脈沖抑制(zhì)器(qì)
(2) Pulse Suppressor: Pulse Suppressor is a simple positioning con×tainer. Its working principle is that air is more compressible than ‍liquid. Pulse flow enters the container and the air bag on the liqui₹d sinks to absorb pulses and then smoothly flows out of the pulse Suppressor.
3.流量随時(shí)間(jiān)變化(huà)，會(huì)衰減。(由于軟管磨損造成)
3. Flow decreases with time. (due to hose wear)
泵的(de)出口壓力有(yǒu)一(yī)定的(de)局限性，一(yī)般不(bù)超過0.3MPa，通(tōng)常在0.1-0.2MPaδ之間(jiān)。
Pump outlet pressure has certain limitations, gene​rally not more than 0.3 MPa, usually between 0.1-0.2 M‍Pa.
