Each rubber hose has a normal working pressure, and the rupture pressure of high-pressure steel wire braided rubber hoses is 3 to 4 times the working pressure. The higher the pressure, the stricter the number of conductor layers and product production. Therefore, the selection of rubber hoses should be based on the actual pressure of the system.

Precautions for using high-pressure rubber hoses:

1. The temperature of the transmitted materials shall not exceed the factory regulations.

2. Keep the tube clean and clean the interior. Prevent foreign objects from entering the descending pulse, blocking the fluid dynamics of transportation, and damaging mechanical equipment.

3. Installation should try to prevent heat sources as much as possible. If necessary, waterproof sleeves or insulation materials can be installed to prevent the hose from contacting the hot mold.

4. Protective measures should be taken at the intersection or friction between high-pressure steel wire braided rubber hoses and mechanical equipment surfaces to prevent damage and rupture of the hoses.

5. When using, it should be kept as vertical as possible, and sharp turns should be avoided when bending.

6. Do not twist the rubber hose before installation, as twisting can cause a decrease in compression strength and loose joints.

7. When setting up high-pressure pipes, prevent them from being in a tight state, retain the corresponding length and capacity, and keep the pipe body loose.

8. During use, the rubber hose should be protected to prevent it from being squeezed.

9. When controlling the gate valve in real-time, it should be gently adjusted to reduce the impact of working pressure on the hose and prevent rupture.

10. It should be equipped with auxiliary facilities such as "U" - shaped cards, sealing rings, measuring cylinders, and T-shaped ones, and the use of other substitutes is prohibited.

The above are the precautions for using high-pressure steel wire braided rubber hoses. In order to avoid accidents, workers should firmly establish safety awareness. Improve the operational skills of maintenance technicians and strengthen their operational training. Hydraulic support maintenance personnel need to master various systems and working principles of hydraulic supports, and be able to operate them accurately, quickly, and correctly.
