What cause high pressure hose crack and how to deal with it
Grain suction hose is mostly made of wear, corrosion and high temperature resistant materials. In most cases, it is rubber or plastic. Commonly used hose materials are as follows:
PVC hose
The hose has excellent chemical corrosion resistance and wear resistance. Therefore, it is suitable for the transportation of a variety of liquids and granular materials. In agricultural grain suction machines, PVC hoses show good anti-aging properties. Therefore, the service life is long. In addition, the production cost of PVC materials is low and has a high cost-effectiveness. However, PVC hoses have poor tensile properties and general thermal stability. Avoid direct sunlight and high temperature environments when using them.
Polyurethane hose
PU hoses have excellent wear resistance and tensile strength. Besides, PU hose is wear and break resistant, and have a long service life. In addition, its elasticity and compressive resistance can reduce the vibration of the grain suction machine. In addition, PU hose is food grade. Thus it is safe for grain suction. However, PU hoses have poor corrosion resistance and are easily eroded by chemicals. In addition, the high temperature resistance is general and it is easy to soften at high temp. The production cost is high and the price is expensive.
Rubber hose
Rubber hose has excellent wear resistance, tensile strength, good elasticity and compression resistance in the transportation of grain and other granular materials. It can reduce the vibration of the grain suction machine. It is also corrosion and aging resistant. Therefore, it has a long service life. However, rubber hose has poor heat resistance. Besides, it is easy to break at low temperatures.
