One or more parts of the rubber hose break and the cracks are neat: the main reason for this phenomenon is that the system pressure is too high, exceeding the pressure resistance of the rubber hose. If the system pressure meets the requirements, check that the actual pressure resistance of the hose used meets the design requirements
Distortion when the rubber hose breaks: This phenomenon is caused by excessive distortion of the hose during installation or use. After the hose is reversed, the structure of the reinforcement layer changes, the gap between the braided wire and the winding wire increases, the pressure strength of the hose is reduced, and the hose is easily cracked under high pressure. Therefore, the hose should not be torqued during the use or retention of the hose. When installing hoses, the shafts of the two connectors should be in the same plane as possible to avoid twisting the hoses during use.
The wire curls at the crack of the rubber hose. There is an obvious neck shrink: the cause of this phenomenon is that the hose is overstretched and deformed, the layers are separated, thereby reducing the pressure strength. The hose shrinks or stretches in the direction of length under high pressure, with a general shrinkage of 2% to -4% under normal condition. If the hose is selected too short during installation, it will be greatly stretched during operation and, in severe cases, it will break or release. If the hose span is too large, the weight of the hose and the weight of the oil can also bring a lot of tension to the hose, in severe cases, the above failure can occur. Therefore, the appropriate solution should be taken on a case-by-case basis. If pulled too tightly during installation, replace the new pipe that lengthens.
