Hydraulic Fittings

Hydraulic Fittings

FASTENERS USED IN HYDRAULIC SYSTEMS

In hydraulic systems, it is used to transfer the fluid from the reservoir to the user staff and in the process of sending the fluid to the reservoir in the user staff. The circuit elements that allow the elements used in the pump, valve, engine, hydraulic cylinder and hydraulic system to be interconnected are called connection elements.

Fittings are the names given to elements such as pipes, hoses, fittings and clamps. The selection of fittings should be determined to provide the required pressure, flow rate and flow rate, and should be in a structure to withstand the operating pressure.

HYDRAULIC PIPES:

It is the circuit element that carries the fluid between certain points in the system and guides the fluid. Pipes are made of stainless steel and light metals, either by cold drawing method or by stitching. Welded pipes are not resistant to high pressures. One of the two important factors in choosing pipes in hydraulic circuits is the desired internal diameter and the other is the wall thickness that can meet the working pressure. In order to achieve the desired pressure and flow rates in hydraulic systems, pipe diameters must be calculated and determined with correct methods.

What Are The Flow Rates That Should Be Used In The Hydraulic System?

PRESSURE LINE:
4m / s up to 50 bar
4.5m / s up to 100 bar
5m / s up to 150 bar
5.5m / s up to 200 bar
6-7m / s after 200 bar
SUCTION LINE:
0.5 to 1.5m / s
RETURN LINE:
2 to 3 m / s
CALCULATION OF THE PIPE DIAMETER:
Q = Flow rate ......... It / min
V = Average velocity ........ m / s
D = Internal pipe diameter .......... mm

HYDRAULIC HOSES

It is especially used in hydraulic systems to connect moving circuit elements. Since the hoses have high flexibility, it is suitable to be used in cases where the system pressure changes frequently, vibrating, and the temperature difference is high. Hoses are made of synthetic rubber. There are one or more steel wire braids between the rubber layers in order to increase their compressive strength.
