How To Choose Hydraulic Tubing

I do not know that you will have questions when choosing hydraulic tubing, how to choose tubing to be suitable? The correct selection of hydraulic tubing can not only ensure the efficient operation of the hydraulic system, but also extend the service life of the system. So, how to choose hydraulic tubing? I will analyze the selection skills of hydraulic tubing in detail from the four key aspects of the hydraulic system's working pressure, tubing inner diameter, temperature requirements and bending radius.

1. Working pressure of hydraulic tubing

When the hydraulic system is started, it often produces instantaneous peak pressure. Therefore, when selecting hydraulic tubing, it is necessary to ensure that the tubing has a safety margin, enough to withstand the pressure generated by the system, and avoid the rupture or damage of the tubing due to excessive pressure. Under normal circumstances, the safety factor of the hydraulic tubing should be set to 2.5 to 4 times to ensure that it can operate stably under various working conditions and provide sufficient carrying capacity.

2. Selection of tubing inner diameter

The inner diameter of tubing will directly affect the velocity and flow of hydraulic oil, resulting in the efficiency of the hydraulic system is reduced. If the inner diameter of the tubing is too small, it will lead to greater pressure loss and heat generation, increasing the burden of the system; If the inner diameter is too large, it will cause the oil flow rate to decrease, which will affect the speed of the hydraulic system actuator. The selection of the inner diameter of the tubing should be based on the flow requirements of the hydraulic system, and the appropriate inner diameter should be selected.

3. Temperature requirements

The operating temperature range of the hydraulic system has a direct impact on the service life of the tubing. Tubing material needs to be able to withstand the minimum and maximum operating temperatures of the system. Common tubing materials such as synthetic rubber tubing, its applicable temperature range is -40℃ to 100℃; PTFE (polytetrafluoroethylene) tubing is suitable for a wider temperature range, from -60 ° C to 200 ° C.

4. Bending radius and flexibility

When installing, the bending radius of the tubing should be greater than the minimum bending radius to avoid damage or aging of the inner wall of the tubing, affecting the fluid transmission efficiency of the system. If the hydraulic tubing bends too much, it may lead to poor oil flow and even cause system failure. In the design of the hydraulic system, the bending of the tubing should be minimized to improve the stability and life of the system.

The above is the Prince hydraulic small series in the working pressure, tubing diameter, temperature requirements and bending radius of the selection of recommendations, in the selection process, can be used as a reference. Reasonable tubing selection can not only improve the efficiency and stability of the hydraulic system, but also effectively extend the service life of the hydraulic system.
