Peristaltic pumps as fluid transfer equipment, in various industries is also very wide range of applications, but peristaltic pumps also have some shortcomings, the following Pratt peristaltic pump manufacturers from the shortcomings of peristaltic pumps to put forward a number of solutions, I hope to help you.
What are the shortcomings of the peristaltic pump:
1. Peristaltic pump pressure limitations:With flexible tubing, it will make the bearing pressure is limited.
2. Peristaltic pump in operation will produce a pulsatile flow.
Peristaltic pump limitations of the solution is.
① Increase the number of rollers, the flow rate will be reduced
② the use of pulse suppressor: pulse suppressor is a simple positioning container, the working principle is that because the air is more compressible than the liquid, the pulse flow into the container, the liquid on the air bag sinks to absorb the pulse and then gently out of the pulse suppressor.
What are the shortcomings of peristaltic pumps and solutions
3. Flow rate changes over time, will decay. (Caused by wear and tear of the hose)
Pump outlet pressure has certain limitations, generally does not exceed 0.3MPa, usually between 0.1-0.2MPa.
