Proper Use of Hydraulic Hoses

There are thousands of reasons why Hydraulic Rubber Hose fails, but with proper precautions, the most common failures can be avoided. Incompatible fluids will cause deterioration, swelling and delamination of the inner rubber layer of the hose assembly. In some cases, the inner rubber layer may also be partially damaged. The hose must be compatible with the fluid being transferred. Make sure that the fluid is compatible not only with the inner rubber layer, but also with the outer rubber layer and joints.

Dry air / stale air

The inner rubber layer of the hose may cause many tiny cracks due to stale or dry air. Sometimes this type of failure is difficult to detect because the hose can still remain flexible, but there are signs of external leakage. To avoid dry or stale air problems, you should confirm that your hose rating is suitable for extremely dry air.

Minimum bending radius

If the minimum bending radius is not met, the hose assembly may fail relatively quickly. In vacuum or suction applications, if the bending radius is exceeded, the hose may become flat in the bending area. This will hinder or restrict the flow of media. If the bend is too severe, the hose may become kinked. To prevent failure of the minimum bend radius hose, the recommended bend radius should be carefully checked.

Worn hydraulic hose

Everyday needs to go through the harsh environment, and its impact will eventually show up on the hose. If not inspected regularly, wear may cause the hose assembly to rupture and leak. Excessive friction between the hose and an external object or even another hose will wear off the coating on the hose and eventually wear the reinforcement. Properly assembled and installed hoses will have a longer life, reducing downtime and maintenance costs.

Hydraulic Rubber Hose

Factors affecting the service life of hydraulic hoses

The hydraulic hose is mainly composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, a multilayer reinforcing layer, and a weather-resistant synthetic rubber outer rubber layer. The inner rubber layer has the function of subjecting the transport medium to pressure, protecting the steel wire or wire fiber from corrosion, and the outer rubber layer protects the reinforcing layer from harm. The reinforcing layer is the skeleton material, which is used to ensure the operating pressure of the hose.

Proper use of hydraulic hose can extend the service life of the hose and improve the power. What are the factors that affect the correct use of hydraulic hoses? The internal diameter of hydraulic hoses, such as the thickness of the water pipe, will directly affect the flow rate and pressure transmission of the hydraulic oil. Flow rate of hydraulic oil.

The working pressure of the hydraulic hose cannot exceed the burst pressure of the hose. Generally, the burst pressure of the hydraulic hose is 4 times the operating pressure. When selecting the hose, you should choose the type of corresponding working pressure to ensure that the pulse pressure of the hydraulic system cannot exceed the burst pressure of the hose. / 2; Regarding the hydraulic lines with particularly frequent pulses, it is necessary to select special hoses with pulses.

Select a suitable hose according to the operating environment and system temperature. If the working temperature is too high for a long time, it will directly affect the service life of the hose, and the pressure resistance of the hose will also greatly decrease. If a special hydraulic medium is used, the user should ensure that the selected hose assembly and its inner and outer layers, joints and O-rings are compatible with the medium. When the hose is in conflict with the hard object when it is in use, it is necessary to protect the sheath on the outside of the hose; the equipment hose must be fixed to the hose without twisting, the movement track is suitable, and the hose is not damaged.
