How To Reduce The Pressure Loss of Hydraulic Tubes?

Hydraulic tubes pressure loss includes along-the-line pressure loss, local pressure loss and total pressure loss. Along-the-line loss is caused by friction and resistance, while local loss is caused by pipeline bending, joints, etc. In order to reduce pressure loss, measures such as increasing the pipeline diameter, reducing the number of elbows and joints, and increasing the liquid temperature can be taken.

Hydraulic tube pressure loss is a common problem in hydraulic systems. It will reduce the efficiency of the hydraulic system and even affect the normal operation of the equipment. So, what are the types of hydraulic tube pressure loss?

Causes of hydraulic tube pressure loss

The pressure loss of hydraulic tubes is mainly caused by factors such as fluid viscosity, friction of the inner wall of the pipeline, fluid velocity change, and fluid turbulence. In addition, local resistance parts such as pipeline bends, joints, and valves will also hinder the flow of liquid, resulting in pressure loss.

Types of hydraulic tube pressure loss

1. Along-the-line pressure loss

Along-the-line pressure loss refers to the pressure reduction caused by friction and resistance when the liquid flows in the pipeline. This loss is related to the length, inner diameter, material of the pipeline, and the properties and flow rate of the liquid.

2. Local pressure loss

Local pressure loss refers to the pressure drop caused by the change in direction, speed and mutual collision of the fluid when the liquid flows through local resistance parts such as elbows, joints and valves in the pipeline. This loss is related to the type, number and installation position of the resistance parts.

3. Total pressure loss

Total pressure loss refers to the sum of the pressure loss along the way and the local pressure loss. It is one of the important indicators for evaluating the performance of the hydraulic system.

Measures to reduce the pressure loss of hydraulic tubes

1. Increase the diameter of the pipeline

Increasing the diameter of the pipeline can reduce the speed of the fluid and reduce the friction resistance of the fluid, thereby reducing the pressure loss along the way.

2. Reduce the number of elbows and joints

Reducing the number of elbows and joints can reduce the turbulence and collision of the fluid, thereby reducing local pressure loss.

3. Increase the temperature of the liquid

Increasing the temperature of the liquid can reduce the viscosity and friction resistance of the liquid, thereby reducing the pressure loss along the way. However, it should be noted that excessively high temperatures may affect the stability and sealing performance of the liquid.

4. Clean hydraulic oil‌

Keeping the hydraulic oil clean can prevent impurities from clogging the pipeline and valves and reduce flow resistance‌.

5. Regular maintenance and inspection ‌

Regularly check and replace the filter and filter to ensure the normal operation of the hydraulic system and reduce the pressure loss caused by filter blockage ‌

Summary ‌

In summary, hydraulic tube pressure loss is one of the important factors affecting the performance of the hydraulic system. By understanding the types and causes of hydraulic tube pressure loss and taking corresponding measures to reduce pressure loss, the efficiency and stability of the hydraulic system can be improved.
