Do You Know about High-temperature Hot Oil Rotary Joints?

High temperature hot oil rotary joint, also known as heat transfer oil rotary joint, is a transitional sealing device that inputs high-temperature fluid medium from a static system to a dynamic rotating system.  Equipment used for conveying high-temperature media in industries such as rubber, leather, textile, and machinery.  The Q-type rotary joint is designed specifically for high-temperature heat transfer oil working conditions and is used in industries such as rubber, leather, textiles, and machinery

The Q-type high-temperature heat transfer oil rotary joint adopts a spherical non-equilibrium structure, which does not require concentricity of the equipment and can automatically adjust concentricity.  The outer tube is directly connected to the roller or dryer and is the main rotating component;  The outer tube body spherical surface, end cap bottom plane, and impregnated graphite ball surface sealing ring, which have been precision machined and electroplated, together form a reliable dynamic sealing friction pair.  When the medium flows through the sealing ring and oil-free bearing, a very thin liquid film is formed, which strengthens the sealing and lubrication, thereby reducing wear and extending the service life.

Specific connection method of Q-type high-temperature hot oil rotary joint:

QD-F type rotary joint one-way flow type - half ring flange connection

QD type rotary joint one-way flow type - threaded connection

QS-GF type rotary joint bidirectional flow internal pipe fixed type - half ring flange connection

QS-G type rotary joint bi-directional flow internal pipe fixed type - threaded connection

QS-XF type rotary joint bidirectional flow internal pipe fixed type - half ring flange connection

QS-X type rotary joint bi-directional flow internal pipe fixed type - threaded connection

High temperature heat transfer oil rotary joint usage parameters: medium: hot oil

Temperature: ≤ 450 ℃

Speed: ≤ 200rpm

Pressure: ≤ 1.8Mpa

Usage of high-temperature hot oil rotary joint:

During the use of high-temperature hot oil rotary joints, attention should be paid to pressure and leakage issues.  To use under parameter conditions, add lubricating grease according to the specified time.
