There are many types of high-pressure steel wire spiral hoses available in the market. When selecting them, users should choose based on their specific development needs. Additionally, it is important to be aware of the precautions required during their application.
The key precautions for using high-pressure steel wire spiral hoses include the following:
The bending radius of the hose must not be less than the specified minimum value to prevent damage to the hose structure or premature wear caused by excessive stretching.
When selecting high-pressure steel wire spiral hoses, the appropriate hose type, size, and technical parameters must be chosen according to the application standards. Misuse or unauthorized substitution is strictly prohibited.
When the working environment changes, the hose should be transported off the ground as much as possible. Avoid dragging it on the ground to prevent scratching the outer cover, which could lead to the corrosion of the reinforcement layer.
When transporting corrosive liquids, the inner wall of the hose should be thoroughly cleaned after use to prevent residual substances from causing long-term corrosion. Alternatively, a hose specifically designed for corrosive media should be used.
Usage precautions for high-pressure steel wire spiral hoses:
Before use, check whether the product specifications and length meet the specified requirements, and conduct a sampling pressure test. The hose can only be used after passing the test.
Inspect the connection between the fittings and the hose to ensure there are no exposed steel wires, and check whether the outer cover shows signs of excessive pressure. If any of these conditions are present, the hose must not be used.
The coating at the top connection of the fittings must not be damaged or exposed. If exposure is found, the fitting cannot be used to prevent loose sealing and subsequent leakage.
For newly installed hoses, the inner wall should be cleaned to prevent rubber particles and dirt from entering the hydraulic system.
Installation requirements for high-pressure steel wire spiral hoses:
During connection, avoid twisting the hose to prevent changes in the focal point of the reinforcement layer, which could lead to premature wear.
After connection, leave a certain amount of slack in the hose length to prevent changes in length due to tensile forces, which could reduce its pressure-bearing capacity.
The fixing clamps for the hose should be placed on the straight line where the trend line and the straight line intersect. The clamps must not bend the hose, nor should they be too loose.
When connecting to moving parts, leave sufficient length to prevent the hose from being affected during movement.
The bending radius during connection must meet the relevant specified requirements.
High-pressure steel wire spiral hoses are widely used in hydraulic supports. Each support typically requires about 10 to 30 hoses. Therefore, the structure, usage methods, and connection techniques of these hoses will directly affect the operational stability of the hydraulic supports.
