There is a close relationship between the hardness and accuracy of the peristaltic pump tube (that is, the peristaltic pump hose). Here's a closer look at the relationship:
First, the impact of hardness on accuracy
Deformation consistency:
The working principle of peristaltic pump is to realize the transportation of liquid through the peristaltic deformation of the elastic tube wall. Therefore, the deformation characteristics of the elastic tube wall have an important influence on the accuracy of the pump.
If the hardness of the peristaltic pump tube is too high, its deformation ability will be limited, which may lead to unstable flow during the transportation process, thus affecting the accuracy.
On the contrary, if the hardness is too low, the tube wall may be prone to wear due to excessive deformation, which will also affect the accuracy.
Pressure stability:
The peristaltic pump will produce a certain pressure when transporting fluid. The hardness of the pipe will affect the stability of this pressure.
Harder tubes may be more resistant to pressure changes, thereby maintaining a more stable output pressure and helping to improve accuracy.
However, if the hardness is too high, it may also cause the pipe to break under high pressure, but reduce the accuracy.
Tightness:
The hardness of the peristaltic pump tube also affects the sealing between it and the pump head.
A moderately hard tube fits better with the pump head, creating a tight seal that prevents liquid leakage and improves accuracy.
Second, the influence of hardness on performance
Wear resistance:
The peristaltic pump tube will be subjected to constant squeezing and friction during use. Moderately hard pipes have better wear resistance and can extend their service life.
If the hardness is too high or too low, it may cause the tube to wear too quickly, which will affect the performance and accuracy of the pump.
Fatigue resistance:
The peristaltic pump tube needs to undergo a continuous cycle of extrusion and relaxation. Moderately hard tubes have better fatigue resistance and can withstand more cycles without damage.
Too high or too low hardness may cause the pipe to crack or deform during the cycle, thereby reducing the accuracy and reliability of the pump.
3. Choose suggestions
Select based on the application scenario:
When choosing a peristaltic pump tube, it is necessary to make comprehensive consideration according to the actual application scenarios and needs. For example, for occasions requiring high-precision transportation, pipes with moderate hardness and strong deformation ability should be selected.
Focus on materials and processes:
The material and process of the peristaltic pump tube will also affect its hardness and accuracy. Pipes with reliable quality and advanced production technology should be selected to ensure that their hardness and accuracy meet the requirements of use.
Regular inspection and replacement:
In order to maintain the accuracy and performance of the peristaltic pump, it is necessary to check and replace the pipe regularly. Check whether the pipe is worn, aged or deformed, and replace it in time.
In summary, there is a close relationship between the hardness and accuracy of the peristaltic pump tube. When selecting a peristaltic pump tube, it is necessary to comprehensively consider application scenarios, materials, processes, and maintenance and other factors to ensure that its hardness and accuracy meet the requirements of use.
