How do you repair a damaged layflat hose
In the construction machinery operation, affected by the outside air temperature, the use of rubber oil hose temperature is too high, which can make the oil temperature rise sharply. The higher the temperature of the oil, the easier the rubber is to age, the worse the elasticity, the lower the strength and sealing performance, and the hose will burst quickly.
In the process of use, if the hose is delivered with oil components, it is necessary to strengthen the frequency of inspection of equipment. Regular inspection of equipment fittings is of great significance to increase production and efficiency.
Therefore, in the operation, when the temperature rise of the hydraulic system is too high or too fast, the reason should be found out in time and eliminated; In summer, especially in continuous operation, necessary cooling measures should be taken. The selection and installation of hoses must be reasonable. When replacing the hose, the length of the hose, the number of wire layers, the shape and size of the joint should be reasonable, and the bending degree of the hose should be reduced as far as possible; When tightening the joint nut, do not distort the hose, excessive bending and distortion will reduce the service life of the hose. Protective measures should be taken for some parts that are prone to friction to prevent the hose from bursting due to long-term wear and tear.
The following introduces the characteristics of the rubber oil hose, in the use of hose points for attention to provide you as a reference:
The characteristics of the rubber oil hose are:
1. The hose is made of special synthetic rubber, which has good oil resistance, heat resistance and aging resistance.
2. High hose bearing pressure, superior pulse performance.
3. The hose tube is tightly combined and soft to use, and the deformation is relatively small under pressure.
4. The hose has good bending resistance and fatigue resistance.
Points to note when using rubber oil hoses:
1. The temperature of the medium transported by the hose and the hose assembly should not exceed -40℃-+120℃ under normal circumstances.
2. Hose and hose assembly, should not be used in the torsion state.
3. Hose and hose assembly should be kept clean, the interior should be flushed clean.
Prevent foreign objects from entering the lumen, blocking the delivery of fluid and damaging equipment.
4. Beyond the service life or storage life of the hose and hose assembly should be tested before continuing to use.
5. The hose and the hose assembly should not be used under the smaller bending radius of the hose to avoid bending or bending near the pipe joint, otherwise it will hinder the hydraulic transmission and transportation of materials.
