Precautions to use the brake system of a car
What’s the different between peristaltic hose and other hoses? Why there is specific hose for peristaltic pump? Let’s talk about it.
We know that peristaltic pump is mainly used in mining, metallurgy, food, oil and chemical and tunnel engineering. We can see all of these are heavy duty applications, so it need a special peristaltic hose with great properties.
Then what are the properties a peristaltic hose should have?
Elasticity
We learned the working method in the last piece that the roller drives the fluid in the hose to move forward. This requires the hose must have elasticity, which means the hose should return to normal after the extruding. However, the fluid rate will not be exact if the hose can’t return to the normal shape.
Abrasion resistance
We know that the roller rubs the outside wall of peristaltic hose constantly, so the hose should be abrasion resistant. Good abrasion resistance can not only avoid the flow turn to large, hose release and inexact low, but also cause huge maintain work. Thus, abrasion resistance is an important index.
Pressure resistance
Pressure resistance is another important index. If the system pressure beyond the max working pressure, the hose will expand and cause it over-abrasion and even burst.
Air tightness
Peristaltic hose requires excellent tightness, because the medium is fluid. If there is any leakage, that will cause big problem.
Corrosion resistance
The fluids in the hose are always chemicals and other corrosion fluids, so it requires the hose has excellent corrosion resistance. Besides, it also requires good temperature and aging resistance.
The peristaltic hoses in the market look the same. But when you buy such hose, you should ask the seller if it can meet your requirements. Because an improper hose will cause problems to the normal use.
