Frequently Asked Questions
What is a rotary joint and how does it function?
A rotary joint (or rotary union) is a precision mechanical device used to transfer fluids, gases, or other media from a stationary supply pipe to rotating machinery. It seals the media dynamically to prevent leakage during rotation.
What types of media can be transferred using rotary joints?
Rotary joints are highly versatile and can transfer a wide range of media including water, steam, thermal oil, coolant, hydraulic fluid, air, and vacuum, depending on the seal design and materials used.
What are the key factors to consider when choosing a rotary joint?
To select the correct rotary joint, you must consider the media type, operating pressure, temperature, rotation speed (RPM), connection size, and environmental conditions of your application.
How can I prevent leakage and extend the life of a rotary joint?
Proper installation, maintaining precise alignment, avoiding dry running, using flexible hoses for connection, and performing regular inspections of the seals are critical steps to prevent leakage and maximize service life.
Are custom rotary joints available for specialized applications?
Yes, custom configurations can be designed to meet extreme temperature, high-pressure, multi-passage, or high-speed requirements to fit specific industrial machinery and operational setups.
