Embodiment Construction

[0029] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] At present, in order to solve the problem that the dynamic balance of the centrifugal compressor rotor is damaged and the rotor balance deteriorates, it can be disassembled after the centrifugal compressor unit is shut down, and the rotor is transported back to the manufacturing plant for high-speed dynamic balance adjustment. , but due to the complex structure of the centrifugal compressor unit, it will take a lot of time to...

Abstract

The invention discloses a centrifugal compressor with a rotor online dynamic balance function, and relates to the technical field of centrifugal compressors. The centrifugal compressor comprises a rotor and a stator. The rotor comprises a receiver and a dynamic balance device. The stator comprises a probe and a transmitter. The probe is connected with the transmitter, the transmitter is in wireless connection with a receiver, the probe is used for collecting distance parameters from the outer circle of the rotor, and the transmitter is used for sending a control signal corresponding to an online dynamic balance adjusting instruction and driving energy to the receiver when monitoring that rotor dynamic balance is abnormal according to the distance parameters. The receiver is connected withthe dynamic balance device, the dynamic balance device is arranged on a main shaft of the rotor, the dynamic balance device is used for driving a weight balance block in the dynamic balance device according to the control signal received by the receiver through the driving energy received by the receiver, and rotor online dynamic balance is achieved.

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...
