Influence of deposits on rotor impellers of a centrifugal blower of a gas-pumping unit on static imbalance

Abstract

Compressor station equipment undergoes a sensitive adjustment process before commissioning. One of its most important tasks is balancing the blower rotor, as a result of which the forces acting in the system are balanced. Unbalance is the imbalance of the rotor, leading to the occurrence of forces and moments that cause vibration, both of the rotor itself and of the entire machine as a whole. Currently, there is no absolutely effective method for gas purification, which negatively affects the flow path of the equipment. This is especially true for gas pumping units that compress associated petroleum gas, as well as for GPUs operating in underground gas storage facilities and used in cases where the pressure of the sampled gas is lower than the pressure in the pipeline and must be raised. All this contributes to the emergence of an imbalance in the system. The work mathematically simulates the effect of deposits on the static balance of the rotor of a centrifugal blower.
