Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation of mechanical equipment, in particular to a combined sound insulation cover for noise reduction during installation of large equipment. Background Art

[0002] Existing sound insulation and noise reduction technologies for industrial equipment primarily utilize building exterior wall sound insulation, rubber vibration isolation pads, hydraulic vibration isolators, and traditional soundproof enclosures. While soundproof exterior wall construction can block and reduce noise transmission, it offers advantages such as simple processing and wide applicability. However, its disadvantages include large space requirements, high material consumption, and unsightly appearance. Rubber vibration isolation pads utilize internal friction to effectively absorb vibration and impact energy, offering advantages such as unrestricted shape, flexible stiffness in all directions within a certain range, spatial spring properties, the ability to withstand multi-directional loads, simple structure, and low cost, making them suitable for mass production. However, their disadvantages include increasing demands for operational comfort and smoothness in construction machinery, which are no longer met by pure rubber block structures. Traditional soundproof enclosures can reduce noise to a certain extent, but once equipment noise becomes excessively loud, their sound insulation and noise reduction effects fall short of the desired level.
