LENFLEX-HOSE ASSEMBLY

SAFETY GUIDE FOR HOSE ASSEMBLIES

There are many factors that can affect the usage condition of the hose assembly. use the hose assembly and hose fittings in the correct way can ensure its reliability and economical efficiency. these factors are as follows;

1, Hose Dimension

The selection of hose inside diameter must be correctly made. if the hose inside diameter is too small it will speed up the medium in the pipe-line, heat the system, lower the efficiency and produce excessive pressure drop which will affect the whole system's capability. if it fixes with a hose clamp or crosses the steel board, the outside diameter of the hose should be paying more attention to.

2, Working Pressure

The dynamic working pressure in this catalog refers to the allowable maximum pressure in the condition of continuously working. According to the safety modulus of hydraulic hose ruled by international standard, we recommend that the working

the pressure is one-quarter of the minimum blast Pressure.

3, Impact Pressure &Fatigue Life-span

After determining the maximum system pressure for a hydraulic system, hose selection can be made. For the hydraulic system's pressure to always be dynamic, there often appears an impact pressure, the maximum impact pressure is much higher than the maximum system pressure. To be lucky, there is an over fallvalve in every hydraulic system, so high impact pressure cannot affect the fatigue life-span seriously. As for hydraulic systems whose impact pressure appears very frequently. we advise you choose the special hydraulic hose which is able to endure the high impact Pressure.

4, Temperature Range

The user must ensure that the temperature is in an allowable range of hose, if exceeding this range, the life-span of the hose will be shortened, and the capacity to endure pressure will get down. if the working condition temperature keeps too high or too low for a long time, we advise you to use the hose spring guard.

5, Chemical Compatibility

If using a special hydraulic medium, the user should ensure the material of the hose inner side and cover, the hose fittings, and O-ring can compatible with the special hydraulic medium.

6, Bending Radius

Pay more attention to its minimum bending radius when installing the hose assembly, if the bending radius is smaller than the minimum one, the capacity of enduring pressure will get down and the life-span of the hose will be shortened.

7, Friction

We advised you use a spring guard if the hose assembly is always in the condition of touching and making friction with a hard object, Any technical question about Stronger Hydraulic hose assembly, welcome to inquire!
