WHAT ARE THE ADVANTAGES OF PERISTALTIC PUMPS USED IN WATER QUALITY SAMPLERS?
â… . THE WORKING PRINCIPLE OF PERISTALTIC PUMP A peristaltic pump is like squeezing a hose full of fluid with your fingers. As the fingers slide forward, the fluid in the tube moves forward. The peristaltic pump also uses the same principle, except that the finger is replaced by a roller. The fluid is delivered by alternately squeezing and releasing the elastic delivery hose of the peristaltic pump. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed in the tube, and the liquid flows along with it. With the wide application of peristaltic pumps, there are more and more peristaltic pump manufacturers . â…ˇ. WHY DOES THE WATER QUALITY AUTOMATIC SAMPLER USE A PERISTALTIC PUMP? In the process of realizing water quality sampling, the water pump used by the automatic water sampler is in most cases a peristaltic pump. what is the reason? 1. No contamination-the liquid only touches the pump tube of the peristaltic p...
