Abstract
This article analyzes the dynamic stability of rotors with magnetic suspension for compressors of gas-pumping units. The main advantages and disadvantages of magnetic pendants of various manufacturers are formulated. A set of measures was developed and described to ensure the dynamic resistance of rotors with magnetic suspension, including balancing the multiplanar shaft and the calculation and measurement method for assembling rotors. Balancing the shaft with the correction of imbalances in their places allows minimizing their residual vector. The method of calculation and measurement provides a reduction in the scope of work on assembling the rotor (increasing economic efficiency, reducing costs) while maintaining the specified manufacturing accuracy. The new method of assembling the rotor includes the preliminary preparation of the shaft and mounted elements (impellers). As a result, the calculation and measurement method for the assembly of rotors provide a reduction in the amount of work on the assembly of the rotor with ensuring its specified accuracy. This, in turn, allows reducing the cost of setting up and adjusting equipment at the compressor station and to ensure the dynamic stability of the rotors and shafts at a high level.
