What fluids are suitable for hydraulic hoses?
4 min read
Hydraulic systems play a vital role in modern industrial and engineering applications, and hydraulic hoses are an indispensable part of these systems. It not only needs to have good flexibility and pressure resistance but also needs to be able to adapt to various complex working environments and transmit different fluid media. This article will discuss in detail the different types of hydraulic hoses and the types of fluids they are suitable for, to help readers better understand and choose hydraulic hoses that suit their needs.
1. Overview of hydraulic hoses
Hydraulic hoses are flexible pipes used to transport liquid or gas pressure, usually consisting of an inner rubber layer, a reinforcement layer (such as steel wire braiding or winding), and an outer rubber layer. According to their different structures, they can be divided into two categories: steel wire braided hydraulic hoses and steel wire winding hydraulic hoses. The former is suitable for medium and low-pressure occasions, while the latter is more suitable for high-pressure environments. In addition, there are other types such as fiber-reinforced hoses, which have the characteristics of lightweight and small bending radius.
2. Classification and applicable fluids of hydraulic hoses
Wire-braided hydraulic hoses
Features: High-strength steel wire braiding is used as the skeleton material, with good pressure resistance and flexibility.
Applicable fluids: Mainly suitable for relatively mild fluid media such as petroleum-based hydraulic oil, lubricating oil, and water-ethylene glycol solution.
Application scenarios: Widely used in engineering machinery, agricultural machinery, coal mining machinery, and other fields, especially in places that require frequent movement.
Wire-wound hydraulic hose
Features: Provides higher working pressure bearing capacity through multi-layer wire winding, and excellent pulse performance.
Applicable fluids: In addition to the petroleum-based hydraulic oil mentioned above, it can also be used for water-based liquids at higher temperatures and some chemicals that are not highly corrosive.
Application scenarios: Often used in high-pressure hydraulic systems, such as metallurgical equipment, injection molding machines, and other heavy industrial fields.
Fiber-reinforced hose
Features: Use synthetic fibers instead of metal wires for reinforcement, which is lighter and easier to operate.
Applicable fluids: Mainly used for conveying light oils or other low-corrosive fluids.
Application scenarios: Suitable for applications with limited space or weight sensitivity, such as internal pipeline connections of aerospace equipment.
Resin hose
Features: Both the inner and outer layers are made of specially formulated resins with excellent chemical stability.
Applicable fluids: Suitable for the transmission of a variety of chemicals and food-grade materials.
Application scenarios: Commonly used in the chemical industry and food processing production lines to ensure that the product is not contaminated while ensuring safety and hygiene standards.
3. How to choose the right hydraulic hose
The following aspects should be considered when choosing the right hydraulic hose:
Working pressure: Determine the maximum working pressure required according to the actual working conditions, and leave a certain margin to ensure safe operation.
Temperature range: Understand the working temperature range of the medium to be transmitted, and ensure that the hose material can withstand changes under extreme conditions without affecting the service life.
Compatibility: Confirm whether the hose material can be in long-term contact with the fluid being processed without chemical reaction or physical property change.
Installation method: Considering the requirements of the on-site layout, select the appropriate connector form (such as ferrule type, JIC37 degree connector, etc.), and pay attention to avoid damage caused by excessive bending.
Maintenance convenience: For inaccessible areas, product models that are easy to replace and repair should be given priority.
The correct selection of the right type of hydraulic hose is crucial to ensure the normal operation of the entire system. Whether from the perspective of meeting specific technical parameters or considering the maximization of economic benefits, it is necessary to make decisions based on a comprehensive consideration of multiple factors. I hope that the information provided in this article can help you have a more comprehensive understanding of various types of hydraulic hoses and their applicable scope, so as to provide strong support for your project.
