Rubber hose is very common in our daily life, what are the precautions for its use? Let's take a look.
1. The rubber hose can only be used to transport the designed medium, and it is strictly forbidden to use the hose to exceed the designed working pressure.
2. The medium temperature of the hose should not exceed the factory requirements, 40°C to 120°C for oil, -30°C to 50°C for air, and 80°C or lower for water emulsion.
3. The rubber pipe should be kept clean, and the inside should be washed and cleaned. Prevents foreign matter from entering the inner cavity, obstructing the delivery of fluids, and damaging the equipment.
4. The hose device should be kept away from the heat source, and the mounting sleeve or heat shield can be used when needed, so as to pass the thermal deterioration of the hose.
5. The rubber pipe should be placed or wiped with a mechanical surface to prevent the hose from bursting due to wear.
6. The hose part should be as close as possible, when bending, it should be avoided, the bending radius should not be too small, it should be greater than 9 times of the outer diameter. There should be a straight segment that is greater than 2 times the outer diameter of the tube.
7. Do not twist the tube during the installation of the rubber tube. The hose is slightly reversed to reduce its strength and loose joints, and the fittings on the electrical hose should be tightened at the time of assembly, not on the joints.
8. When installing the hose, it should be avoided when the tension is avoided, and it must have a certain length and the hose is loose. During daily use, it is necessary to protect the hose to prevent it from being crushed and smashed.
9. The operation control valve is gentle to reduce the pressure impact on the hose and prevent the hose from bursting. The hose must use the matching regular "U" card, sealing ring, two-way, three-way, etc., and it is strictly forbidden to use other substitutes. If the hose is leaking, cracked, bulging, corroded joints, broken wires, aging cracks in the adhesive layer, etc., it must be replaced immediately. During daily use, it should be inspected and replaced.
