Abstract

The invention discloses a centrifugal compressor with a rotor online dynamic balancing function, which relates to the technical field of centrifugal compressors and includes a rotor and a stator, the rotor includes a receiver and a dynamic balancing device, the stator includes a probe and a transmitter; the probe is connected to the transmitter , the transmitter and the receiver are connected wirelessly, the probe is used to collect the distance parameters between it and the outer circle of the rotor, and the transmitter is used to send online dynamic balance adjustment instructions to the receiver when the rotor dynamic balance is detected to be abnormal according to the distance parameters Corresponding control signals and driving energy; the receiver is connected with the dynamic balance device, which is arranged on the main shaft of the rotor, and the dynamic balance device is used to drive the dynamic balance device according to the control signal received by the receiver, using the drive energy received by the receiver. The counterweight balance block in the balance device realizes the online dynamic balance of the rotor.

Description

technical field [0001] The invention relates to the technical field of centrifugal compressors, in particular to a centrifugal compressor with a rotor online dynamic balancing function. Background technique [0002] Centrifugal compressors are generally multi-stage, which can make the gas obtain higher pressure. In some centrifugal compressors, due to technological reasons, the process gas will undergo polymerization reaction and produce coking. For example, the product gas contains olefins and high-carbon gases. When compressed, due to the increase in temperature, coking will occur, and the coke will stick. The aerodynamic performance of the centrifugal compressor is seriously affected on the impeller, diffuser and other centrifugal compressor flow passages and components. The uneven coverage of the coke or the sudden shedding of parts will affect the balance of the rotor of the centrifugal compressor, which will cause the centrifugal compressor to vibrate beyond the stand...
