HU25038 leaf petiole combination seal

Description of HU25038 leaf petiole combination seal

The HU25038 leaf petiole combination seal is a high-performance sealing device used in the blade adjustment mechanisms of industrial fans or compressors. Its main purpose is to prevent medium leakage and ensure the flexibility and sealing of the blade shank movement. Its design combines the dual advantages of fluid dynamic balance and contact sealing, demonstrating excellent sealing performance and service life under complex working conditions such as high-speed rotation, high temperature, and high pressure.

Performance of HU25038 leaf petiole combination seal 

This sealing component adopts a combined structure, typically consisting of elastic sealing elements, support rings, and compression devices, achieving comprehensive radial and axial sealing of the blade shank through precision cooperation. Its core functions include: on one hand, effectively preventing gas or liquid media from leaking along the blade shank gap, ensuring stable internal pressure and operational safety; on the other hand, reducing friction and wear between moving parts, extending the service life of the blade shank and bearings.

The HU25038 sealing component is often made of high-temperature and corrosion-resistant composite materials to adapt to harsh working environments in industries such as chemical, power, and metallurgy. Some designs also introduce fluid dynamic balance structures, using medium pressure to automatically adjust sealing contact force, reducing wear and improving sealing reliability. This technology has been successfully applied in slurry pump and compressor impeller seals.

In fan blade adjustment systems, the HU25038 combination seal demonstrates excellent dynamic response characteristics, adapting to mechanical stress changes caused by frequent blade angle adjustments, while significantly reducing maintenance frequency and operational costs. Its modular design also facilitates on-site installation and replacement, further improving equipment availability and economic efficiency.
