## Calculate hydraulic line: step-by-step guide for accurate calculation

Hydraulic lines are an important component of hydraulic systems and are used to transfer pressurized fluids. Proper hydraulic line sizing is critical for optimal system operation. The dimensioning of the hydraulic lines depends on various factors such as the flow rate, the pressure and the length of the line.

Hydraulic line calculation is a complex process and requires a thorough understanding of hydraulic technology. Incorrect hydraulic line design can result in loss of power, increased energy consumption and even damage to the system. Therefore, it is important to use the correct formulas and calculation methods.

To determine the correct nominal size of the hydraulic line, various factors must be taken into account. These include the flow rate, the pressure, the length of the line, and the type and size of the connections. An accurate calculation of the hydraulic line is therefore essential to ensure optimum performance and efficiency of the hydraulic system.

### Hydraulic line selection

Hydraulic line selection is an important step in hydraulic system design and installation. There are several factors that must be considered in the selection process to ensure that the line meets the requirements of the facility.

#### Selection of the suitable pressure range

When selecting the hydraulic line, it is also necessary to consider the pressure range in which the line will be operated. It is important to choose a line that meets the requirements of the installation to avoid line failure. The pressure range is usually specified in bar or psi.

It is important to know the maximum operating pressure of the system and to select a line that can withstand this pressure. A line that is too weak can lead to line failure, while one that is too strong can be unnecessarily expensive.

#### Selection of the suitable diameter

The diameter of the hydraulic line is an important factor in the selection. Too small a diameter can result in increased pressure drop, while too large a diameter can be unnecessarily expensive. The diameter is usually specified in millimeters.

The choice of the right diameter depends on various factors, such as the flow rate, the oil velocity and the pressure drop. A line that is too small can result in increased pressure drop, while one that is too large can be unnecessarily expensive. It is important to choose the diameter carefully to ensure that the line meets the requirements of the plant.

The following oil velocities apply as a guide value for a hydraulic oil HLP46 with 40°C oil temperature:

Suction lines: 0.5…1.5 m/s

Return lines: 2…4 m/s

Pressure lines: 3…8 m/s

#### Samples

Suction line: At 50 l/min, the minimum inner diameter is 26.58 mm, the maximum diameter is 46.04 mm. Here, an inner diameter of at least 30 mm should be selected.

Return line: At 50 l/min, the minimum inner diameter is 16.28 mm, the maximum diameter is 23.02 mm. Here, an inner diameter of at least 18-22 mm should be selected.

Pressure line: At 50 l/min the minimum inner diameter is 11.51 mm, the maximum diameter is 18.80 mm. Here, an inner diameter of at least 12 to max. 18 mm can be selected.

Further information on nominal sizes can be found on Wikipedia, among other places.
