  • CENTRIFUGAL COMPRESSOR
    Publication number: 20190093675
    Abstract: A centrifugal compressor includes a compressor head, a motor, a cooler, a support frame, a load-bearing beam and a bottom plate. The cooler and the support frame are fixedly mounted on the bottom plate, the load-bearing beam is arranged above the cooler and the support frame, the support frame supports the load-bearing beam, the compressor head and the motor are arranged above the load-bearing beam, and the compressor head and the motor are fixedly mounted on the load-bearing beam. The centrifugal compressor avoids the problem of triggering resonance, extending the service life of the whole machine.
