Steel wire braided rubber hoseAs a component of the hydraulic system, the stability and safety of its performance are directly related to the operational efficiency and lifespan of the entire system. During use, the bending amount often changes continuously with the development of various factors, such as the movement of the actuator, the layout of the pipeline, and the influence of the external environment. Therefore, it is crucial to control the bending amount of the steel wire braided rubber hose reasonably to ensure the normal operation of the hydraulic system. Here, we will discuss in detail how to effectively control the bending amount from multiple aspects such as setting the bending radius, precautions for installation and connection, and maintenance and management during use.

1、 Set a reasonable bending radius

The key to controlling the bending amount of steel wire braided rubber hoses lies in setting a reasonable bending radius. Generally speaking, the curvature radius should be greater than 10 times the diameter of the hose to ensure that the hose will not be damaged due to excessive stretching or compression during the bending process. This principle is particularly important at the pipeline connections of hydraulic systems, as they often bear significant pressure and dynamic loads. If the bending radius is too small, it may not only cause damage to the internal structure of the hose, but also lead to serious consequences such as leakage or even fracture.

When selecting and installing steel wire braided rubber hoses, one should refer to the recommendations in the product manual and consider the actual usage conditions comprehensively. At the same time, attention should be paid to avoiding bending near the root of the joint, as stress concentration is more pronounced here, which can easily cause cracks or fractures. Therefore, the shortest distance from the steel wire braided rubber hose joint to the starting bending point should be greater than 6 times the outer diameter of the pipe to ensure that the strength and sealing of the joint are not affected.

2、 Precautions for installation and connection

When installing and connecting steel wire braided rubber hoses, it is also necessary to follow a series of specifications to ensure reasonable control of bending, and avoid applying torque or keeping the hose in a tight state during installation. Because tensioned rubber hoses are prone to expansion under pressure, which reduces their strength and durability. Therefore, during installation, the hose should be kept loose and leave sufficient length allowance to accommodate possible bending changes.

Secondly, the connecting part should be able to hang freely to avoid unnecessary bending due to its own weight. If the hose needs to move on two different planes, a clip should be installed at an appropriate position to divide it into two parts, so that each part moves on the same plane to reduce the additional bending caused by twisting.

In addition, attention should be paid to the connection quality between the steel wire braided rubber hose and the joint. When tightening the joint nut, avoid twisting or over stretching the hose. The correct approach is to tighten the connector onto the hose, rather than tightening the hose onto the connector. This can ensure that the sealing and strength of the joint are not affected, while reducing the bending stress caused by improper connection.

3、 Maintenance and management during use

Regular maintenance and management are also important means to control the bending amount during the use of steel wire braided rubber hoses. Regular inspections should be conducted on the rubber hose to observe for any cracks, wear, or aging. Once an abnormal situation is discovered, a new hose should be replaced promptly to avoid safety accidents.

Secondly, during the operation of the hydraulic system, close attention should be paid to the temperature rise of the system. High temperature environments can accelerate the aging and damage process of rubber hoses, so steel wire braided rubber hoses should be installed as far away from heat sources as possible. If high temperature environments cannot be avoided, protective measures such as insulation panels should be installed to reduce heat transfer.

In addition, attention should be paid to avoiding friction and collision between the steel wire braided rubber hose and other components. Long term friction and collision can cause wear and cracking on the surface of the rubber hose, thereby reducing its strength and durability. Therefore, during installation and use, the independence of the rubber hose should be maintained as much as possible to avoid unnecessary contact with other components.

Controlling the bending amount of steel wire braided rubber hoses is one of the important measures to ensure the normal operation of hydraulic systems. By setting a reasonable bending radius, following installation and connection precautions, and strengthening maintenance and management during use, the stress and damage generated during the bending process of rubber hoses can be effectively reduced, thereby extending their service life and improving the operating efficiency of the system.
