What are hydraulic hoses?
A hydraulic hose is a means of transportation for hydraulic oil, which transmits kinetic energy and power. High pressures are usually present in the pipes to pump viscous fluids quickly to their destination.
How to choose the most suitable hydraulic hose for you?
There are many hydraulic hose classifications, and choosing the most appropriate product according to your needs is especially important. Below we summarize the selection points for you:
-
Determine the purpose and requirements:
Before selecting a hydraulic hose, the purpose and requirements of the system must be determined. First, pressure, temperature, compatibility with fluids, and installation requirements should be considered to meet the project's needs.
-
Identify the appropriate hose type:
In general, we have several types of hydraulic hoses to choose from, including standard hoses, spiral hoses, braided hoses, and multi-coil hoses. Each type has its own advantages and disadvantages, so it is important to choose the right type according to the needs of the system.
-
Select the correct hose size:
Next, please choose the correct hose size for its optimum performance and safety. The hose determines the size's inside diameter (ID) and outside diameter (OD). It is important to choose a hose that can handle the required flow and pressure.
-
Check the compatibility with fluid:
Then, check the hydraulic hose for compatibility with the fluid being used. Hose material should be compatible with the chemical composition, temperature, and pressure of the fluid. Compatibility charts assist in selecting the correct hose material.
-
Consider the hose fittings:
Also, check that the fittings match the hose and have the proper pressure rating. It is essential to check the compatibility of hoses and fittings.
-
Check the operating temperature:
Check that the temperature range of the hydraulic hose is within the recommended range. Hoses used in extreme temperatures require specific materials that can withstand the temperature range.
-
Check the working pressure:
Check whether the hydraulic system's working pressure is within the hose's rated pressure range. Hoses under pressure may rupture or burst, resulting in a hazardous situation.
-
Consider the bending radius:
Check that the bend radius of a hydraulic hose is the smallest radius the hose can bend without kinking or damaging the hose. Hoses should be selected based on the bend radius required for the system.
-
Check the length required:
Finally, the length of the hydraulic hose needed should be accurately measured. Hoses should be cut to the required size, ensuring there is no unnecessary slack in the system.
-
Follow the manufacturer's guidelines:
Of course, it is important to follow the manufacturer's guidelines for selecting, installing, and maintaining hydraulic hoses. This guide provides essential information on hose performance, installation, and maintenance.
Following these steps, you can select the appropriate hydraulic hose for your system, ensuring optimal performance and safety.
What are the areas of application for hydraulic hoses?
Hydraulic hoses are essential in engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in different industrial sectors.
What are the advantages of hydraulic hoses?
Advantage：
1. The rubber hose is made of special synthetic rubber, which has excellent oil, heat, and aging resistance.
2. The tube body is tightly combined, soft to use, and has little deformation under pressure.
3. The rubber hose has excellent bending resistance and fatigue resistance.
4. The rubber hose has high bearing pressure and excellent pulse performance
What are the pressure ratings and temperature limits for the hydraulic hoses?
Oil -40°C to 100°C; Air -30°C to 50°C; Water -0°C to 80°C.
What are the common standards and certifications for hydraulic hoses?
Commonly used standards for hydraulic hoses include DIN, SAE, ISO, and GB/T standards;
The standards for steel wire braided hydraulic hoses are DIN EN 853, SAE J517, GB/T 3683-2011, ISO1436;
The steel wire wound hydraulic hoses standards are DIN EN 856, SAE J517, GB/T 10544-2003, and ISO3862.
