Hydraulic Hoses
Hydraulic Hoses
Hydraulic Hoses
It is especially used in hydraulic systems to connect moving circuit elements to each other. Since the hoses have high flexibility, they are suitable for use in situations where the system pressure changes frequently, there is vibration, and the temperature difference is high. Hoses are made of synthetic rubber. In order to increase the compressive strength, there are one or more steel wire mesh-windings between the rubber layers.
Hydraulic Hoses are special synthetic rubber and thermoplastic products with a bottom layer that is resistant to hydraulic oils. They are special synthetic rubber and thermoplastic hoses, reinforced with high-strength steel wire mesh, and whose upper layer is wrapped against hydraulic oils, abrasion that may occur from external factors and all kinds of weather conditions. In hydraulic hoses, the outer braid layers can be up to 6 layers.
Single Layer Wire Braided Hoses are produced in accordance with R1AT, R1A or 1SC, 1SN standards.
Double Wire Braided Hoses are produced in accordance with ISO (American) Norm R2AT, R2A or EN (European) Norm 2SC, 2SN.
4 Layer Wire Braided Hoses are produced in accordance with ISO (American) Norm R9, R12 or EN (European) Norm 4SP, 4SH.
6 Layer Wire Braided Hoses are produced in accordance with ISO (American) Norm R13, R15 or EN (European) Norm 6SP, 6SH.
Hydraulic Hoses are used in work machines requiring high pressure, piloting equipment of work machines, elevators, high pressure water washing works, high pressure hot water washing works, hydraulic systems suitable for very high peak pressures and difficult conditions, hydraulic controlled units, high pressure hydraulic oil. They are used in fuel oil, grease, water and air discharge, low pressure and return hydraulic systems, air brake systems in the automotive industry and hydraulic brake systems of road vehicles.
R1 Hydraulic Hose
Made of oil resistant synthetic rubber, single steel braid reinforced, oil and weather resistant synthetic hose coating. Synthetic rubber can be used to hold the wire mesh inside the hose together using the appropriate material.
R2 Hydraulic Hose
Made of oil-resistant synthetic rubber, two layers of steel braid reinforcement, oil- and weather-resistant synthetic hose coating. Synthetic rubber can be used to hold the wire mesh inside the hose together using the appropriate material.
R9 Hydraulic Hose
Tube inside oil resistant synthetic rubber, 4 spiral windings of variable direction are made of oil and weather resistant synthetic coating. Synthetic rubber is used to grasp the wire winding inside the hose and hold it together by using suitable material.
R13 Hydraulic Hose
The tube inside the oil-resistant synthetic rubber is made of high-strength steel spiral winding in different directions, oil and weather resistant synthetic coating. Synthetic rubber is used to grasp the wire winding inside the hose and hold it together by using suitable material.
R15 Hydraulic Hose
The tube inside oil-resistant synthetic rubber is made of oil- and weather-resistant synthetic coating with 4 or 6 layers of high-strength steel spiral wound. Synthetic rubber is used to grasp the wire winding inside the hose and hold it together by using suitable material. It is a heavy duty, high strength, spiral braid reinforced hose.
PRESSING OF HYDRAULIC HOSE FITTINGS
Before pressing, the dimensions of all selected materials (Hoses, Sockets and Unions) should be checked.
Hoses and nozzles that are not compatible with each other should never be used together.
The mold size and settings of the machine where pressing will be done should be checked.
Old materials should never be reused. (Removing the fittings and pressing them again or pressing a new fitting onto the old hose)
Since the hose pressing process directly affects human life in many cases, people who do the pressing process should think about what kind of problems may arise from the smallest mistake made and should pay due attention to the pressing process.
Mistakes that can be made during the pressing process are as follows:
1.Delivering Hydraulic Hose with Fittings Without Pressing the Fittings onto the Hose
2. Incorrect calculation of the pressing size or misreading from the table and pressing
3. Pressing process to the right size but with the wrong mold
4. Performing the pressing process without sufficiently inserting the couplings into the hose.
5. Deterioration that may occur due to the couplings hitting the jaws of the press when pressing elbow or bent special couplings.
6. A part of the socket remains outside the mold during the pressing process.
THINGS TO BE CONSIDERED WHEN CONNECTING HYDRAULIC HOSE
Different pipe diameters should not be used in hydraulic systems, and sudden cross-sectional narrowing or cross-sectional increase should be avoided.
Sharp corners should be avoided in turns in lines used in hydraulic systems.
Excessively long and unnecessary pipe and hose lines should be avoided.
To prevent vibration and cavitation in the system, pipes should be fixed with clamps at regular intervals.
The suction pipe must be short.
The return pipe must be short.
Hoses should be used in moving and vibrating areas.
Thermal expansion should be taken into account in pipe connections.
Pipe diameters must be large enough to provide the desired flow rate and pressure.
Pipe wall thickness and hose type must be selected to meet the working pressure and temperature values.
Pipe and hose connections must be leak-proof.
Pipe inner surfaces must be smooth.
The innermost layer of the hose must be resistant to the fluid used in the system.
