AI Technical Summary

Technical Problem

In the low-temperature, dry environment of food processing production lines, motor noise is relatively loud, which affects the health of workers. In addition, low temperatures cause the lubricant to deteriorate, increasing mechanical friction and component wear, and reducing motor performance.

Method used

The structure employs a design that incorporates diagonally penetrating vents, sound-absorbing sheets, fiber sound-absorbing coatings, rock wool sound insulation layers, and sound-absorbing materials within a closed cavity. This design reduces noise reflection, increases sound wave absorption, and alters the direction of sound propagation. Combined with a porous structure that reflects and absorbs sound waves, it also reduces noise. Simultaneously, it optimizes air circulation to ensure effective heat dissipation.

Benefits of technology

It significantly reduces motor operating noise, improves the working environment, extends motor life, enhances stability and reliability, and reduces the risk of noise-induced hearing damage.
