Safety Guide For Hose Assemblies

Safety Guide For Hose Assemblies (一)

There are many factors which can affect the usage condition of the rubber hydraulic hose assembly, use the hose assembly and hose fittings in a correct way can ensure its reliability and economical efficiency, those factors are as follow:

1. Rubber Hose Hydraulic Hose Dimension

The selection of the 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 paid more attention.

2.      Working Pressure

The dynamic working pressure refers to the allowable maximum in the condition of continuously working. According to the safety modulus of hydraulic hose ruled by international standards,we recommend that the working 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 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 overfall valve in every hydraulic system, so high impact pressure can’t affect the fatigue life –span seriously. As for the hydraulic system whose impact pressure appears very frequently, we advise you choose the special hydraulic hose which is able to endure the high impact Pressure.
