In cutter suction equipment, the tail rotary joint serves as the "joint" connecting the fixed pipeline and the rotating excavator arm. This rotary joint ensures leak-free transmission of high-pressure media between the relatively moving parts, ensuring smooth operation and reliable operation.
The tail rotary joint utilizes a multi-channel coaxial rotary seal principle to create an efficient media transmission channel. Its core structure consists of a high-precision rotating core shaft and a stationary housing, which achieve relative rotation via a precision bearing system.
As dredging equipment evolves towards intelligent and larger scale, tail rotary joint technology continues to innovate and break through. The application of cutting-edge technologies such as magnetic fluid seals and self-healing composite materials is driving the product's evolution towards greater reliability and intelligence. As a key component of cutter suction equipment, technological advancements in rotary joints will continue to enhance the continuity and reliability of dredging operations, providing stronger equipment support for hydraulic engineering projects.
