DN500 XZ Maintenance-Free Rotary Compensator

XZ Maintenance-Free Rotary Compensator is an industrial device used for thermal compensation in pipelines, primarily applied in industrial pipeline systems, especially in fields such as petroleum, chemical, power, and metallurgy. Its core function is to absorb axial, angular, and radial displacements caused by temperature changes, fluid flow, and other factors, thereby ensuring the stable operation of the pipeline system.

Working Principle

The XZ Maintenance-Free Rotary Compensator utilizes fluid dynamics principles and precise mechanical structural design to effectively compensate for axial, angular, and radial displacements in pipelines caused by temperature variations, fluid flow, and other factors. Its uniqueness lies in its maintenance-free feature, which reduces system complexity and maintenance costs.

Structural Features

The XZ Maintenance-Free Rotary Compensator consists of a sealing outer sleeve, flexible graphite packing, nuts and bolts, a spring assembly, a packing gland, and a spring compression flange. A compression spring is installed between the packing compression flange and the upper compression flange, with the longitudinal section of the compression flange designed as a U-shaped groove ring. A ball-type rolling ring, which moves in coordination with the reducer pipe, is placed within the U-shaped groove ring and between two fixed rings at the right end face of the inner conduit.

Application Scenarios

The XZ Maintenance-Free Rotary Compensator is widely used in various industrial pipeline systems, particularly in high-temperature and high-pressure environments. Its scientifically designed sealing surface structure ensures an extremely low wear rate between the sealing material and the sealing surface, achieving long-term leak-free performance. This is a critical safety assurance for pipeline systems operating under high-temperature and high-pressure conditions.
