What Everybody Ought To Know About Hydraulic Hose

Hydraulic hose: mainly composed of liquid resistant synthetic rubber inner layer, middle rubber layer, multi-layer reinforcement layer and weather resistant synthetic rubber outer layer.

The inner rubber layer has the effect of making the conveying medium bear pressure, protecting the steel wire or wire fiber from erosion, the outer rubber layer protects the enhanced layer from damage, the enhanced layer is the skeleton material, the role is to ensure the use of pressure hose.

Two, hydraulic hose use: Mainly used for mine hydraulic support, oil field development, Suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization and automation of hydraulic system with certain pressure and temperature of oil in the base (such as mineral oils, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and liquid Move. Rubber and plastic material hydraulic hose is also known as rubber and plastic hose, is a new type of hose, its corrosion resistance and energy saving effect is obvious.

Three, hydraulic hose working temperature: -40℃ ~ 120℃ four, product specifications range: DN2.5mm ~ DN305mm.

Due to the complex variety of hose, diverse structure, and different use conditions, the service life of hose is not only determined by the quality, but also determined by the correct use and maintenance. So even if the product has a very high quality, if it can not be used and maintained correctly, it will seriously affect the quality and life of its use, and even serious accidents that should not occur, causing losses to property. The following points for attention are provided:

1.Hose and hose assembly can only be used to transport the designed material, otherwise the service life will be reduced or failure.

2, the correct use of hose length, hose length changes under high pressure (-4%-+2%) and length changes caused by mechanical movement.

3. Hose and hose assembly shall not be used under pressure (including impact pressure) exceeding the designed working pressure.

4, hose and hose assembly conveying medium temperature under normal circumstances, should not exceed -40℃-+120℃, otherwise it will reduce the service life.

5, hose and hose assembly should not be less than the minimum bending radius of the hose, avoid bending or bending near the pipe joint, otherwise it will hinder hydraulic transmission and conveying materials or damage the hose assembly.

6. Hose and hose assembly should not be used in torsion state.

7. Hose and hose assembly should be handled carefully, should not be dragged on sharp and rough surfaces, should not be bent and flattened.

8, hose and hose assembly should be kept clean, the internal should be washed clean (especially acid pipe, spray pipe, mortar pipe). Prevent foreign objects from entering the cavity, hindering the delivery of fluid and damaging the equipment.

9, exceed the service period or storage period of the hose and hose assembly to carry out experimental identification before continuing to use.
