Live Demonstration: Hydraulic Seal Kits in Installation

At our 120㎡ interactive booth, engineers showcased 6 tailored sealing systems through real-time equipment simulations:

1. TBM Main Drive Seal Assembly (For 12m+ Diameter Tunnel Boring Machines)

Configuration: 3x lip seals + 2x anti-extrusion rings + 1x debris scraper

Key Innovation:

Patented staggered-angle lip design reduced friction torque by 38%

2,000-hour continuous test data displayed via live dashboard (99.5% efficiency retention)

2. Crane Boom Cylinder Repair Kit (For 100T+ Mobile Cranes)

Components Included:

Primary U-cup seals (PU90 material)

Secondary buffer seals (HNBR with steel reinforcement)

Wear bands (Glass fiber-reinforced PTFE)

Field Efficiency:

Cutting downtime from 8 hours to 2.5 hours using our pre-assembled kits.

3. Excavator Travel Motor Seal System

Application-Specific Design:

Triple-layered dust exclusion system

Emergency leak containment structure

Performance Validation:

Conducted 200-cycle pressure tests (0-45MPa), recording only 0.03mm lip wear.

More than 300 customers came to the scene to watch and exchange knowledge about sealing parts. 158 customers took samples on the spot and placed orders, and 27 customers made appointments to visit our factory.
