Cloth lined rubber hose, wear-resistant and oil resistant hydraulic system matching
In hydraulic systems, hydraulic hoses serve as important connecting components, and their quality and performance directly affect the overall efficiency of the equipment. In this context, DN25 hydraulic hoses play an indispensable role in coal mining equipment. This article will explore in detail the definition, characteristics, applications, and maintenance of DN25 hydraulic hoses, allowing us to gain a deeper understanding of this "hidden hero" in the coal mining industry.
1、 Definition of DN25 hydraulic hose
DN25 hydraulic hose refers to a hydraulic hose with a nominal diameter of 25 millimeters, commonly used for conveying hydraulic oil or other liquids. DN stands for "nominal diameter", and the number 25 indicates that the inner diameter of the pipeline reaches 25 millimeters. Hydraulic hoses not only need to have good compressive performance, but also need to resist oil corrosion, wear, and various harsh environmental conditions to ensure that their performance can be maintained under long-term high load operation.
2、 Characteristics of DN25 hydraulic hose
1. High quality materials
DN25 hydraulic hoses are typically made of multi-layer composite materials, with the outer layer typically made of wear-resistant polyurethane material and the middle layer typically using a steel wire braided structure to enhance the pipeline's compressive and tensile strength. In addition, the inner layer material needs to have good chemical stability to avoid corrosion of the rubber hose caused by hydraulic oil.
2. High voltage resistance performance
The design of DN25 hydraulic hose requires strict testing to ensure its safety performance under high pressure conditions. Usually, its pressure resistance value can reach 15MPa or even higher, making it suitable for various high-pressure hydraulic systems.
3. Strong flexibility
Although hydraulic hoses need to have strong compressive performance, they also require good flexibility. The DN25 hydraulic hose can bend freely in various installation environments without causing changes in the inner diameter, ensuring smooth liquid transmission.
4. Temperature resistance
In working environments such as coal mines, hydraulic systems often encounter high or low temperature challenges. Therefore, the temperature resistance range of DN25 hydraulic hoses is usually between -40 ° C and+100 ° C, and some products can even withstand more extreme temperatures, ensuring the normal operation of the equipment under various conditions.
3、 Application fields of DN25 hydraulic hose
DN25 hydraulic hose is widely used in coal mining equipment and other mechanical fields, mainly including:
1. Coal mining equipment
In coal mining, hydraulic supports, hydraulic excavators, and various hydraulic transportation equipment all rely on the support of DN25 hydraulic hoses. Efficient transmission of hydraulic oil ensures stable operation of supporting equipment under high loads and maintains mining efficiency.
2. Coal mine transportation system
The flexibility and wear resistance of hydraulic hoses make them an indispensable component in coal mine transportation systems. When using hydraulic lifting systems and conveyor belts, DN25 hydraulic hoses can ensure the safe and effective transportation of materials.
3. Equipment maintenance
In the daily maintenance of equipment, DN25 hydraulic hoses are often replaced or repaired. Its standardized specifications make replacement simple and convenient, greatly reducing equipment downtime.
4、 Maintenance and upkeep of DN25 hydraulic hose
Regular inspection and maintenance are essential to ensure the long-term use of DN25 hydraulic hoses.
1. Regular inspection
Regularly inspect hydraulic hoses for signs of aging, damage, oil leakage, and other issues. If any problems are found, they should be replaced in a timely manner to avoid affecting equipment efficiency or even causing safety hazards.
2. Cleaning and maintenance
During the operation of hydraulic systems, pollutants and impurities can easily enter the hydraulic oil. Therefore, it is necessary to regularly clean the hydraulic hoses to prevent excessive accumulation of dirt inside, which can affect the efficiency of fluid transmission.
3. Ensure stable connection
At the connection of the DN25 hydraulic hose, it is essential to ensure the stability of the fasteners to prevent hydraulic oil leakage caused by loose connections, which can lead to equipment failure and safety hazards.
4. Reasonable storage
Hydraulic hoses that are not used for work should be stored in a cool, ventilated, and dry place, avoiding direct sunlight and high temperature environments to prevent the hose material from aging and becoming ineffective.
5、 Summary
DN25 hydraulic hose is a crucial component in coal mining equipment, and its performance directly affects the safety and efficiency of the equipment. Understanding its characteristics, application scope, and maintenance points can undoubtedly provide strong support for the operation of coal mining enterprises. In order to ensure the stable operation of hydraulic systems, enterprises should pay attention to the selection and maintenance of DN25 hydraulic hoses to achieve equipment performance and safety assurance.
With the advancement of technology, the manufacturing process of hydraulic hoses will continue to improve. In the future, DN25 hydraulic hoses may adopt more advanced materials and technologies to cope with more complex working environments. All of this indicates that hydraulic hoses will continue to play an indispensable role in the development of the coal mining industry.
