Auxiliary Components

Product Highlights

Auxiliary components for tail seal brushes are critical to ensuring stable installation, continuous sealing, and long-term reliable operation.

Xinda treats these auxiliary components as integral parts of the tail sealing system rather than simple accessories. Through systematic design and precise matching, they ensure stable and effective performance of tail seal brushes under high water pressure and complex working conditions.

Performance Advantages

Secure Fixation, Anti-Displacement

Clamping and fixing structures keep the tail seal brush correctly positioned during advance, preventing loosening or misalignment caused by vibration or water pressure.

Integrated with Grease Injection, Enhanced Sealing

Works in coordination with the grease injection system to form a stable grease film between the brush and segment, significantly reducing leakage risk.

Protection and Guidance, Extended Service Life

Protective and guiding features reduce direct abrasion at the brush root, minimizing abnormal wear and extending overall service life.

Maintainable Design, Easy On-Site Replacement

Maintenance-friendly structures facilitate installation, removal, and adjustment of tail seal brushes, reducing maintenance complexity.

Applicability

Compatible with tail seal brushes, brush boxes, and grease injection systems for various shield machines and TBMs.
Configurable according to shield type, operating conditions, and maintenance strategies, supporting both new equipment and in-service upgrade requirements.
