Vibration Table Body Configuration
1. Moving coil
The vibrating table is equipped with cast and manually machined moving coils, optoelectronic load support system and dual bearing axial guidance. Dual bearing guidance is a unique feature that helps reduce dynamic axial crossing and rotation during vibration testing for superior durability.
2. Excitation coil
Double magnetic circuit structure, low flux leakage, uniform magnetic field.
3. body surface
Using advanced phosphating treatment and car paint technology, it has long-term anti-wear and anti-rust effects.
4. Table refrigeration:
Adopt low-noise fans and improve the air intake structure of the table body. The excitation coil adopts a honeycomb air duct, and the middle magnetic ring adopts a double-layer shunt air duct. A new air duct design is adopted to enhance the cooling effect.
