Hydraulic Hose Life And Safety
Hebei Siberia Special Rubber Co.,Ltd | Updated: May 26, 2017

Hydraulic hose mainly by the liquid-resistant inner layer, the middle layer, 2 or 4 or 6 layers of steel wire wound reinforcement layer, the outer layer composition, the inner layer has the transmission medium to withstand the pressure to protect the wire from erosion, The outer layer protects the steel wire from damage, and the steel layer is the reinforcing material of the skeleton material.

Hydraulic hose is mainly used for mine hydraulic support, oil field mining, suitable for engineering construction, lifting transport, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and industrial sectors mechanized, automated hydraulic system (Such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) and the like, and for liquid transmission with a certain pressure (higher pressure) and temperature , The maximum resistance to working pressure up to 60MPa.

Hydraulic hose use precautions

First, the pipe diameter: the inner diameter of the hose.

Second, the hose in the use and design should pay attention to the following matters:

1, the bending radius of the hose should not be too small, generally should not be less than "hydraulic hose assembly technical characteristics" in the provisions of the value. The length of the hose assembly shall not be less than twice the outer diameter of the pipe.

2, the length of the hose assembly should take into account the hose in the pressure oil, the length will be shrinkage deformation, the general shrinkage of the tube length of 3 to 4%. Therefore, when the hose assembly is installed, it is not allowed to be tightened.

3, hose assembly in the installation should ensure that no distortion occurred. The joint axis of the hose should be placed in the plane of motion as much as possible to avoid damage to the hose at both ends.

4, the hose should be avoided with the sharp parts of the mechanical contact and friction, so as to avoid damage to the tube.

Third, the safety measures: In order to ensure the safe and reliable use of hydraulic hose assembly, the following special attention.

1, the pressure: hose specified working pressure is usually not less than the maximum system pressure, only in the case of infrequent use, it is allowed to increase by 20%; for frequent use, often bent to reduce the 40%. If the impact pressure of the system is higher than the working pressure specified by the hose, it will not only reduce the service life of the hydraulic hose, but also may cause the personal equipment accident.

2, temperature: fluid temperature and ambient temperature, whether it is stable or instantaneous, shall not exceed the temperature limit of the hose, the temperature is lower than or higher than the recommended temperature of the hose, can reduce the hose performance, resulting in hydraulic soft Tube damage, causing leakage.

3, fluid compatibility: the fluid in the hose, should be consistent with the product samples in the "use" made in the provisions of the provisions beyond the use of the pipe can not guarantee the life and safety.

4, the appropriate end of the connection: the nuts are easy to connect, low cost is widely used, but the vibration of the larger case, to fully take into account the nut loose problem, take the hair blue connection.
