Asphalt distributor rotary joint
Asphalt distributor rotary joint
Product Introduction
Modern asphalt distribution trucks generally have four fluid systems, namely hydraulic transmission system, thermal oil heating system, asphalt distribution system, and compressed air system. Correspondingly, mechanical design also requires high standards, especially for foldable spray pipelines, which require asphalt and thermal oil to be transmitted through rotary joints, making the structure more complex. The use of double-layer insulated metal hoses, coaxial rotating dual medium transmission sealing structure, and the application of Hall element devices form easuring vehicle speed have effectively solved the functional problems of the equipment. SD Company has successfully developed the application of asphalt rotary joint technology.

Product Features
Modern asphalt rotary joints can circulate four fluid systems, namely hydraulic transmission system, thermal oil heating system, drainage and distribution system, and compressed air system.
