The use of the above-mentioned structure can, on the one hand, provide good sound absorption and noise reduction for the three-stage vacuum machine assembly installed in the combined frame by virtue of the structural enclosure, thereby reducing noise pollution generated during the operation of the equipment. On the other hand, by covering the surfaces of the first protective plate, the second protective plate, and the third protective plate with explosion-proof film, the structural strength of the first protective plate, the second protective plate, and the third protective plate can be guaranteed to a certain extent. With the structural support of the combined frame, the three-stage vacuum machine assembly can be provided with structural protection as much as possible, and damage to the three-stage vacuum machine assembly caused by external forces can be reduced as much as possible, thereby ensuring the service life of the three-stage vacuum machine assembly and the safety of its operation.
