Abstract

The invention discloses a centrifugal compressor with a vibratory diffuser blade. The centrifugal compressor comprises an air incoming chamber, an impeller, a diffuser, a curve, a return flow device and a volute, the diffuser blade for diversion is arranged in the diffuser and connected with a partition through a diffuser blade rotating shaft, and a vibration exciter is connected with the diffuser blade through a transmission mechanism. When the vibration exciter works, vibration is generated and transmitted to the diffuser blade, and the diffuser blade vibrates around the diffuser blade rotating shaft and actively controls a flow field in the diffuser; or the diffuser blade is connected with an elastic element through the transmission mechanism, and when gas flows through the diffuser, the diffuser blade generates self-excited vibration to realize self-adaptive control on the flow field in the diffuser. In the constantly-changing flow field, the blade slightly vibrates around a rotating shaft, a runner is enabled to be capable of effectively adapt to flowing change, separation in flowing is reduced, energy loss is lowered, and overall performance of the diffuser is improved.

Description

technical field

[0001] The invention belongs to the technical field of centrifugal compressors, and relates to a centrifugal compressor with oscillating diffuser blades. Background technique

[0002] With the rapid development of industrial technology, as an important equipment in metallurgy, building materials, electric power, petroleum, chemical industry, environmental engineering and other industrial sectors, the role of centrifugal compressors in production has been paid more and more attention, and it is a key energy-consuming power equipment , its current development trend is: to further increase its pressure ratio, increase its load, and at the same time require its working conditions to adapt to a wide range. Therefore, the continuous and stable operation of centrifugal compressors, as well as energy-saving and consumption-reducing technologies, are a primary and urgent problem to be solved.

[0003] In this context, in order to reduce the loss of the flow process a...
