How to reduce the peristaltic pump pulsation Peristaltic pump or constant flow pump pulsation is restricting the development of an important factor, due to its working principle and structure of the restrictions, there is no real solution to completely solve the problem of pulsation, we can only through certain technical means to larger To limit the peristaltic pump or constant flow pump pulsation, the specific practices are the following: 1. Select the finer hose at the same flow rate: The pump with a thin hose will have a small pulsation flow rate per revolution; 2. The use of pulse damping device: the principle of using air compression, absorption pulsation; 3. Increase the number of wheels: increase the frequency of pulsation, reduce the amplitude of pulsation; 4. The use of two pump head or low pulsation pump head (the same principle), the roller offset angle: the use of pulsation cross-complement elimination of pulsation; 5. Using back pressure (the pressure of the output): the output pressure to pump tube deformation absorption pulse.
