Core Introduction And Selection Guide for Hydraulic Rotary Joints

Hydraulic specialized rotary joint is a type of rotary joint specifically used in hydraulic systems, which can transmit hydraulic medium while rotating, achieving dynamic connection of hydraulic systems. The following is a detailed introduction to hydraulic specialized rotary joints:

1、 Definition and Function

Hydraulic specialized rotary joint is a specially designed rotary joint that can maintain the sealing and transmission of hydraulic medium while rotating. This type of joint is commonly used for rotating components in hydraulic systems, such as rotating workbenches, rotating ends of hydraulic cylinders, etc., to achieve the transmission and control of hydraulic energy.

2、 Structure and Characteristics

Hydraulic specialized rotary joints are usually composed of joint bodies, seals, bearings, and other components. Among them, the joint body is the core part of the joint, which is responsible for connecting and supporting rotating components; Seals are used to maintain the sealing of hydraulic media and prevent leakage; Bearings are used to support rotating components, reducing friction and wear.

Hydraulic specialized rotary joints have the following characteristics:

a. Good sealing performance: High quality sealing materials and structures are used to ensure that the hydraulic medium does not leak during rotation.

b. Smooth operation: Precise bearings and lubrication system are used internally to ensure smooth and noise free operation of rotating components.

c. High pressure resistance: able to withstand high hydraulic pressure, ensuring the stability and safety of the system.

d. Wide applicability: It can be used for rotating components in various hydraulic systems, such as machining center rotating worktables, hydraulic workstations, etc.

3、 Working principle

The working principle of hydraulic specialized rotary joints is that when the rotating component rotates, the sealing element inside the joint body rotates and maintains contact and sealing with the rotating component. At the same time, the hydraulic medium is transmitted to the hydraulic actuator of the rotating component through the channel inside the joint body, achieving the transmission and control of hydraulic energy.

4、 Application and Selection

Hydraulic specialized rotary joints are widely used in rotating components of various hydraulic systems, such as machining centers, hydraulic workstations, coilers, converters, and other equipment. When choosing hydraulic specialized rotary joints, the following factors need to be considered:

a. Work pressure: Choose the appropriate connector model and specification based on the system's work pressure.

b. Medium type: Select the appropriate sealing material and sealing structure based on the type of hydraulic medium used in the system.

c. Rotation speed: Select the appropriate bearing type and lubrication method based on the rotation speed of the rotating components.

d. Installation space: Choose the appropriate joint size and shape based on the installation space of the equipment.

5、 Maintenance and upkeep

In order to ensure the long-term stable operation of hydraulic specialized rotary joints, regular maintenance and upkeep are required. Specific measures include:

a. Regular inspection: Regularly check the sealing performance and operation of the joints, promptly identify and handle problems.

b. Cleaning and replacement: Regularly clean the impurities and dirt inside the joint, replace severely worn seals and bearings.

c. Lubrication and maintenance: Regularly add lubricant to the joints to maintain the lubrication status of the bearings and seals.
