Short description
Guideline VDI 3836 lays down criteria for the evaluation of vibrations in screw compressors and Roots blowers when measurements are taken at the non-rotating and rotating components of these machines in their place of installation. These criteria are also applicable to acceptance measurements of compressor stages carried out in the manufacturer's test facilities. As a basic rule, guideline VDI 3836 applies to rigidly or resiliently mounted compressors with outputs as shown in Table 1 (see Section 4.1.2), when powered by an electric motor or a steam turbine. In the case of multiple-stage compressors of compact design the evaluation criteria should be applied to each of the stage air ends. For less powerful machines, application of this guideline can be by agreement between the manufacturer and the customer. Guideline VDI 3836 does not apply to compressors powered by internal combustion engines. The evaluation criteria presented in guideline VDI 3836 do not apply to the vibrations of the driving machines which should be evaluated on the basis of the corresponding standards.
