The installation of steel wire braided rubber hoses is related to their application in hydraulic systems. Improper installation may lead to serious consequences, especially when components are subjected to unacceptable torsional stress. This not only concerns the stable operation of the hydraulic system, but also directly affects the safety and service life of the equipment.

1、 The generation and harm of torsional stress

In hydraulic systems, the installation position, angle, and fixing method of steel wire braided rubber hoses need to be carefully designed and constructed. Once installed improperly, such as too small a bending radius, too large a deviation in installation angle, or unreasonable setting of fixing points, it may cause unnecessary twisting force on the rubber hose during operation. This torsional force will gradually accumulate and transform into torsional stress, acting on various components of the hydraulic system.

The harm of torsional stress should not be underestimated, as it may directly cause damage to the steel wire weaving layer inside the hose, reducing the pressure bearing capacity and service life of the hose. Secondly, torsional stress can also be transmitted to key components such as hydraulic cylinders, pumps, valves, etc. through connectors, causing serious consequences such as sealing failure, increased bearing wear, and even fracture of these components. More seriously, hydraulic systems that are subjected to long-term torsional stress may experience overall performance degradation, affecting equipment stability and safety, increasing maintenance costs and downtime.

2、 Installation strategy to avoid torsional stress

In order to effectively avoid torsional stress on steel wire braided rubber hoses in hydraulic systems due to improper installation, the following aspects can be taken into account:

1. Reasonable design of installation path: Before installation, the overall layout of the hydraulic system should be fully considered, and the direction and length of the hose should be planned reasonably to ensure that the hose can bend naturally during installation, avoiding sharp bends and excessive twisting.

2. Strictly control the bending radius: The bending radius of the steel wire braided rubber hose should not be less than its specified minimum value to reduce stress concentration during bending. At the same time, multiple bending at the same position should be avoided to reduce fatigue damage to the rubber hose material.

3. Correct setting of fixed points: The position and quantity of fixed points should be reasonably determined based on factors such as the length, diameter, and working pressure of the hose. The fixing point should be firm and reliable, and able to effectively limit the movement range of the hose, preventing unnecessary twisting during operation.

4. Use specialized connectors and fixtures: Choose reliable specialized connectors and fixtures to ensure a tight and stable connection between the hose and hydraulic components. At the same time, the fastening of joints and fixtures should be regularly checked to prevent torsional stress caused by looseness.

5. Strengthen training and supervision: Provide professional training to personnel involved in the installation and maintenance of hydraulic systems to enhance their understanding of the importance of installing steel wire braided rubber hoses. At the same time, strengthen supervision and inspection during the installation process to ensure that all installation requirements are strictly implemented.

Improper installation of steel wire braided rubber hoses in hydraulic systems may result in unacceptable torsional stress on components, leading to a series of serious consequences. Therefore, it is necessary to attach great importance to the installation of rubber hoses and strictly control every link from design, construction to maintenance. Only in this way can the stable operation of the hydraulic system and the long-term safe use of the equipment be ensured.
