Description
technical field [0001] The invention belongs to the technical field of rotational speed detection, and in particular relates to a device and method for detecting the rotational speed fluctuation of a bearing for a compressor. Background technique [0002] With the development of larger, higher and faster compressor performance, the bearing on the compressor rotor generates more heat, and a series of factors such as the increase of the rotor speed make the rotor vibrate and destabilize, and the bearing performance problem becomes more and more serious. More and more severe, the bearings on steam turbines and compressors are required to have higher requirements and higher standards. The current bearing inspection method is to put the bearing parts on the instrument, and manually measure whether the size of each part of the bearing is within the specified range. If the size of each part of the bearing is within the specified range, it is a qualified product; otherwise, that is ...
