Use and Storage of Hydraulic Rubber Hoses

Hydraulic hose is mainly composed of liquid-resistant synthetic rubber inner rubber layer, middle rubber layer, multi-layer reinforcement layer and weather-resistant synthetic rubber outer rubber layer. The inner rubber layer has the function of making the conveying medium bear pressure and protecting the steel wire or wire fiber from erosion, the outer rubber layer protects the reinforcing layer from damage, the reinforcing layer is the skeleton material, the function is to ensure the use pressure of the hose. Industrial hose manufacturer LUHONG introduces you to the basic structure of hydraulic hoses, as well as precautions for use.

Use

Hydraulic hose use: mainly used in mining hydraulic support, oilfield development, suitable for engineering construction, lifting transport, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, a variety of machine tools and various industrial sectors mechanized, automated hydraulic system with a certain pressure and temperature of petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsion, water) and other liquid transmission. Hydraulic hoses made of rubber and plastic materials, also known as rubber and plastic hoses, are a new type of hoses with obvious corrosion resistance and energy-saving effects.

Precautions

Hydraulic hose use precautions due to the complex variety of hose, a variety of structures, coupled with the use of different conditions, so the length of service life of the hose, not only determined by the quality of good or bad, but also determined by the correct use of maintenance. The following precautions for use are provided.
2, the correct use of the length of the hose. The length of the hose will change under high pressure, and the mechanical movement will cause the length to change.
3、Hydraulic hoses and should not be used under pressure (including shock pressure) that exceeds the designed working pressure.
4、The temperature of the medium conveyed by the hydraulic hose should not exceed -40℃-+120℃, otherwise it will reduce the service life.
5、Hydraulic hose should not be used under less than the minimum bending radius of the hose, avoid bending or bending near the pipe joint, otherwise it will hinder the hydraulic pressure transmission and transport materials or damage the hose assembly.
7、Hydraulic hoses should be handled carefully and should not be dragged on sharp and rough surfaces, and should not be bent and flattened.
8、The inside of the hydraulic hose should be flushed clean. Prevent foreign objects from entering the cavity and obstructing the transmission of fluid and damaging the equipment.
9、The hoses and hose assemblies that exceed the service period or storage period should be experimentally identified before they can be used.

Hose storage

The storage room where the hose is stored should be kept clean and ventilated, with relative temperature below 80%, and avoid the hose being exposed to direct sunlight and rain and snow.
Hydraulic hose storage, should be placed separately according to the different varieties of specifications, do not mix stacked, and marked with a sign to get access.
Hydraulic hose storage, and should not be acid, alkali, oil and organic solvents or other corrosive liquid, gas contact.
Hydraulic hose in storage, the body of the tube is strictly prohibited to stack heavy objects, and to prevent external extrusion and damage.
Hydraulic hose storage time generally should not exceed two years, and should be the first into the first use, to prevent the storage of too long and affect the quality of the hose.
