How to choose coal mine rubber hose?

Coal mine rubber hose is a kind of elastic conveying equipment specially designed for high-pressure environments such as coal mines. It is usually used for the transportation of water, air, mineral slurry and other substances inside the mine. Due to the complex environment, high pressure and flammability of coal mines, the design and manufacture of coal mine rubber hoses are strictly required to ensure their safety and durability under harsh conditions.

The main features of coal mine rubber hose are:

High strength: Coal mine rubber hose needs to have high compressive capacity to withstand the high-pressure material transportation in the mine.

Abrasion resistance: Due to the large amount of solid particles in the mine environment, the rubber hose needs to have good wear resistance.

Anti-aging: The temperature, humidity and chemical environment in the mine may cause the hose to age, so the coal mine hose needs to have a strong anti-aging ability.

Flame retardant: Coal mine hoses need to have flame retardant properties to reduce the risk of fire accidents in coal mines.

Antistatic: Static electricity may be generated in coal mines, so coal mine hoses need to have antistatic properties to prevent fires caused by static sparks.

Environmental protection: Coal mine rubber hose should not produce harmful substances during use, so as to protect the health of miners and the mine environment.

When selecting large-diameter hoses for coal mines, the appropriate hose should be selected according to the specific conditions of the mine and the type of material to be transported. At the same time, attention should also be paid to regularly checking the condition of the rubber hose to ensure its safe and reliable operation.
When selecting and using coal mine rubber hose, in addition to the factors mentioned above, the following points need to be considered:

Hose size: Select the appropriate size coal mine hose according to the flow rate of the material to be transported and the size of the mine space. Generally speaking, the larger the inner diameter of the hose, the greater the flow rate of the transported material.

Connection method: The connection method between the coal mine rubber hose and other equipment is also a factor that needs to be considered. Common connection methods include flange connections, clamp connections, and quick connectors. Choosing an appropriate connection method can ensure a tight connection between the hose and the equipment and prevent leakage.

Bending radius: Coal mine hose may need to bend in tight spaces during use. The bending radius refers to the minimum bending radius that the hose can withstand when bending. Selecting a hose with an appropriate bend radius can avoid damage caused by excessive bending.

Working pressure: Different coal mine hoses have different working pressures. Select the appropriate rubber hose according to the pressure requirements of the material to be transported to ensure that it can withstand the working pressure in the mine.

Scope of application: Coal mine rubber hose is suitable for various types of mines, including coal mines, metal mines and non-metal mines. When selecting a hose, it is necessary to ensure that it is suitable for the specific type of mine environment.

In short, when selecting a coal mine rubber hose, multiple factors such as its performance, size, connection method, bending radius, working pressure and scope of application should be considered comprehensively to ensure that it meets the needs of the mine. At the same time, it is necessary to regularly check the condition of the rubber hose during use, and ensure its correct installation and maintenance, so as to prolong the service life of the rubber hose and ensure the safety in the mine.
