The phenomenon of rubber hose being flattened during use is a common and puzzling problem. Many users often feel confused and helpless when they encounter this situation. Today, I'm going to break down the reasons behind this phenomenon from the perspectives of physics, chemistry, and engineering, and provide some solutions.
First of all, we need to understand the structure and properties of rubber hoses. Rubber hoses usually consist of an inner layer, an outer layer, and a reinforcing layer. The inner tube is responsible for carrying the fluid, the overlay is used to protect the inner layer, and the reinforcement layer provides mechanical strength. Rubber itself is a material with high elasticity and good wear resistance, but under certain conditions, the phenomenon of sucking flat can also occur.
The reasons for the use of rubber hoses may be as follows:
1.Piping system pressure is too high:When the pressure of the piping system is too high, the extrusion force of the rubber soft joint will increase, and it is easy to be flattened and deformed.
2.Improper installation angle of the piping system:The installation should be adjusted according to the natural curvature of the pipeline, and the angle is too small or too large may cause the rubber soft joint to be flattened.
3.The exhaust system design is not reasonable or imperfect:The unreasonable or imperfect design of the exhaust system in the piping system may cause the pipeline to be difficult to eliminate the air leakage, so that the rubber soft joint generates negative pressure and is flattened.
4.The quality and manufacturing process of the rubber soft joint itselfFor example, the insufficient thickness and strength of the rubber sheet may lead to the rubber soft joint being flattened.
5.Bending causes suction:Rubber hoses are often bent during use, and if they are not bent properly, they will affect their normal use and even lead to suction. Therefore, when installing, make sure that the bending radius of the soft joint is large enough that there is no excessive bending.
6.Too large eccentricity or too small bend radius:When the eccentricity of the piping system is large or the bending radius is too small, it will lead to the flattening of the rubber soft joint. This is because the eccentricity or bending radius is too small to cause the pipe to generate both tensile and compressive forces, and the rubber soft joints have a limited load-bearing capacity to withstand this force, resulting in flattening.
In order to avoid the occurrence of rubber hose suction flattening, the following measures can be taken:
1.Choose the right rubber hose material and model to meet the requirements of the working environment.
2.During installation and use, make sure that the bending radius of the rubber hose is large enough to avoid excessive bending.
3.For the exhaust system in the piping system, it should be reasonably designed to ensure smooth exhaust and avoid negative pressure.
4.Regularly inspect and maintain rubber hoses, and identify and replace faulty hoses in a timely manner.
Please note that there are many reasons for the phenomenon of rubber hose suction, and we need to prevent it from many aspects, and the above analysis and solutions are for reference only. In practice, other factors may need to be considered, such as temperature, media properties, etc. If the problem is complex or cannot be solved, it is advisable to consult a relevant professional.
