Description

A hydraulic swivel joint, also known as a hydraulic cathead, is a crucial component used in hydraulic systems to allow rotational movement while maintaining fluid connection. It enables the transmission of hydraulic power and fluid between stationary and rotating parts, facilitating efficient operation in various industrial applications.

Key Features

Rotational Fluid Transfer: The hydraulic swivel joint enables the rotation of connected components while ensuring a continuous flow of hydraulic fluid. It allows for the transfer of pressurized fluid, such as oil or hydraulic fluid, from the stationary part to the rotating part, providing flexibility and freedom of movement.

Sealed Connection: The swivel joint incorporates sealing mechanisms to prevent leakage or loss of hydraulic fluid during rotation. This ensures the integrity of the hydraulic system and maintains consistent performance and reliability of connected equipment.

Customizable Specifications: Hydraulic swivel joints come in various specifications to accommodate different hydraulic system requirements. Common parameters include maximum pressure rating, flow capacity, port sizes, mounting options, and rotation angle. Customization allows for compatibility with specific machinery configurations and desired hydraulic performance.

Robust Construction and Durability: These swivel joints are constructed using high-quality materials such as stainless steel or brass for corrosion resistance and durability. They undergo precision machining to ensure accurate dimensions, smooth rotation, and reliable performance even under demanding operating conditions.

Specifications

Standard sizes for hydraulic swivel joints may vary depending on industry standards and manufacturer guidelines. Maximum pressure ratings typically range from 500 psi to 10,000 psi, while flow capacities vary based on the desired hydraulic fluid volume. Port sizes are standardized according to common hydraulic fittings and hose sizes. Standard sizes are determined based on compatibility with hydraulic systems and industry practices.

Material and Manufacturing Process

Hydraulic swivel joints are commonly made of high-quality materials such as stainless steel, brass, or alloy steel. Stainless steel provides excellent corrosion resistance, while brass offers good thermal conductivity and durability. The manufacturing process involves precision machining techniques like CNC turning and milling to achieve accurate dimensions and smooth surfaces. Sealing components, such as O-rings or seals, are integrated during assembly to ensure leak-free operation.

Technical Structural Features

The hydraulic swivel joint consists of two main parts: a stationary housing and a rotating section. The housing contains fluid ports for connection to the hydraulic system, while the rotating section allows free rotation. The sealing mechanism ensures a secure and sealed connection between these two sections, enabling the transfer of hydraulic fluid while accommodating rotational movement.

Installation and Usage

Hydraulic swivel joints are installed within hydraulic systems, typically incorporated into machinery or equipment where rotational movement is required. They are securely mounted using appropriate fastening methods and connected to the hydraulic lines or hoses. During operation, the swivel joint allows for rotational movement while maintaining a continuous flow of hydraulic fluid between the stationary and rotating parts. Regular maintenance, including inspection and lubrication, ensures optimal performance and longevity of the swivel joint.

Processing advantage

1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.

2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.

3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
