Hydraulic pipe types

 

Hydraulic equipment plays a key role in modern industry. Its fluid connection lines and hydraulic hose assemblies, as core components, directly determine the performance and reliability of the equipment. This article will comprehensively and in-depth explore the specific content and application of various hydraulic equipment fluid connection lines, hydraulic hose assemblies, beer pipes and hydraulic pipes.

 

Basic principles of hydraulic systems

 

Before exploring hydraulic pipes, it is necessary to understand the basic principles of hydraulic systems. The hydraulic system uses the incompressibility of liquids and the ability of liquids to transmit pressure under pressure to achieve mechanical energy conversion by transmitting hydraulic energy. Simply put, the hydraulic system presses the liquid into the hydraulic pipeline through a pump, and the flow of liquid drives the actuator to achieve the specified action, thereby performing different mechanical operations.

 

Types and applications of hydraulic pipes

 

As an important part of the hydraulic system, the quality and selection of hydraulic pipes directly affect the operating efficiency and safety of the system. The following are several common hydraulic pipelines and their application characteristics:

 

1. Steel pipe (seamless steel pipe)

 

- Features: high strength, high pressure resistance, high temperature resistance;

 

- Application: suitable for industrial equipment, heavy machinery and high-pressure hydraulic systems with high requirements.

 

2. Copper pipe

 

- Features: good corrosion resistance, stable cold and hot performance, good thermal conductivity;

 

- Application: widely used in air-conditioning systems, refrigeration equipment and special hydraulic equipment.

 

3. Nylon pipe

 

- Features: light, flexible, wear-resistant and oil-resistant;

 

- Application: commonly used in medium and low pressure hydraulic systems, small equipment and agricultural machinery, etc.

 

4. Polytetrafluoroethylene (PTFE) pipe

 

- Features: high temperature resistance, corrosion resistance, extremely low friction coefficient;

 

- Application: suitable for hydraulic systems in high temperature, high pressure and special chemical environments.

 

Hydraulic hose assembly

 

Hydraulic hose assembly is an important component of the hydraulic system. Its main function is to serve as a transmission medium for liquids, while having certain flexibility and pressure bearing capacity. The material selection, specifications and performance of hydraulic hose assemblies are directly related to the operating efficiency and failure rate of the equipment.

 

1. Hose material

 

- Rubber hose: good elasticity, high pressure resistance, vibration resistance, suitable for general hydraulic systems;

 

- Plastic hose: light weight, corrosion resistance, often used in special environments or equipment with high flexibility requirements;

 

- Metal hose: high temperature resistance, corrosion resistance, suitable for high temperature, high pressure and harsh working conditions.

 

2. Inner and outer layer design

 

- Inner layer: needs to have the characteristics of hydraulic oil resistance, high temperature resistance and high pressure resistance, usually using synthetic rubber or nylon materials;

 

- Outer layer: needs to have the characteristics of wear resistance, aging resistance, corrosion resistance, etc., often using polyurethane, PVC or braided metal and other materials.

 

3. Joints and clamps

 

- The joints and clamps of hydraulic hoses are also crucial components. High-quality joints and clamps can ensure the stability and good sealing of hydraulic pipe connections. Common joints include ferrule joints, flange joints and quick-connect joints.

 

Beer pipes

 

Beer pipes, as the name implies, are mainly used in beer delivery systems. This type of pipe is made of special materials and requires good food-grade safety, corrosion resistance and antibacterial properties. It is usually made of polymer materials, composite materials or stainless steel to ensure that the beer is not contaminated or affected during delivery.

 

1. Material characteristics

 

- Food-grade plastics: light, soft, easy to operate, and have good antibacterial and corrosion resistance;

 

- Food-grade rubber: thicker and pressure-resistant, suitable for delivery systems with temperature and pressure requirements;

 

- Stainless steel pipes: high temperature resistant and corrosion-resistant, suitable for high-end beer production and delivery systems.

 

2. Cleaning and maintenance

 

- Beer pipes need to be cleaned and disinfected regularly to avoid bacteria and dirt accumulation that affect the taste and quality of beer. It is generally recommended to clean thoroughly after each use and use food-grade detergents during the cleaning process.

 

Comprehensive classification of hydraulic pipes

 

There are many types of hydraulic pipes. In addition to the commonly used hydraulic steel pipes and hydraulic hoses, there are also the following categories:

 

1. High-pressure hydraulic pipes

 

- High-pressure hydraulic pipes are suitable for high-pressure environments and are commonly used in construction machinery, engineering machinery and high-pressure systems. They are usually composed of multiple layers of steel wire braiding or winding reinforcement layers to improve pressure resistance.

 

2. Low-pressure hydraulic pipes

 

- Low-pressure hydraulic pipes are suitable for relatively low-pressure hydraulic systems, such as agricultural machinery and light industrial equipment. The material is relatively soft and flexible, and is often composed of fiber braiding reinforcement layers.

 

3. Thermoplastic hydraulic pipes

 

- Made of thermoplastic materials, it has excellent chemical resistance and wear resistance, is suitable for use in corrosive environments, and is widely used in agricultural machinery, chemical equipment and mobile equipment.

 

4. Ultra-high-pressure hydraulic pipes

 

- Ultra-high-pressure hydraulic pipes withstand higher pressures and are often used in fields such as water jet cutting and ultra-high-pressure cleaning equipment. They are usually wound with multiple layers of steel wire to ensure safety and reliability under ultra-high pressure.

 

How to choose the right hydraulic pipe and hose assembly

 

Selecting the right hydraulic pipe and hose assembly requires consideration of multiple aspects to ensure the normal operation and long life of the hydraulic system:

 

1. Pressure level:

 

- According to the working pressure of the hydraulic system, select pipes and hoses that can withstand the corresponding pressure to ensure safety and reliability.

 

2. Temperature range:

 

- According to the operating temperature range of the system, select suitable temperature-resistant pipes to avoid material performance degradation and shortened life due to changes in ambient temperature.

 

3. Medium compatibility:

 

- Different hydraulic media have different requirements for pipes. Pipes compatible with the medium must be selected to avoid chemical reactions and material damage.

 

4. Use environment:

 

- Select pipes according to the specific conditions of the use environment. If special requirements such as corrosion resistance, wear resistance, and fire resistance are required, select materials with corresponding characteristics.

 

5. Flexibility requirements:

 

- Consider the flexibility required by the equipment, select pipes with appropriate softness and bending radius to ensure simple, efficient and safe pipeline layout.

 

Installation and maintenance of hydraulic pipelines

 

1. Correct installation

 

- Follow the installation specifications to ensure that the joints are firmly positioned and well sealed, and avoid excessive bending and squeezing of the pipelines.

 

2. Regular maintenance

 

- Regularly check the wear and sealing performance of the pipelines, and replace aging and damaged parts in time to maintain the normal operation of the system.

 

3. Cleaning and maintenance

 

- Keep the system clean to prevent impurities and dirt from entering the pipelines and causing blockage and wear.

 

4. Emergency treatment

 

- Develop emergency plans, equip with necessary maintenance tools and spare parts to ensure rapid response and handling when problems occur in the pipelines.

 

Through the above comprehensive introduction, I believe that everyone has a deeper understanding of the fluid connection pipelines and hydraulic hose assemblies of hydraulic equipment. These key components are essential for the efficient and safe operation of hydraulic systems. Choosing appropriate pipes, reasonable maintenance and installation specifications are the core elements to ensure the performance and service life of hydraulic systems.
