Description

TECHNICAL FIELD

[0001] The utility model relates to impeller technical field more specifically, the utility model relates to a kind of angle-adjustable compressor impeller structure. BACKGROUND

[0002] By adjusting the angle of impeller blade, the performance of compressor under different operating conditions can be optimized. In the low-speed small-flow region, by adjusting the blade angle, the cascade stall phenomenon can be alleviated, thereby improving the stability and efficiency of the compressor. The angle-adjustable impeller structure enables the compressor to adapt to a wider range of operating condition changes. Whether the flow is increased or decreased, the optimal operating state of the compressor can be maintained by adjusting the blade angle, thereby widening its operating range.

The outlet end of the device is connected to the inlet of the centrifugal compressor in the form of flange connection, which can adjust the circumferential angle around the compressor inlet and be fixed by screws. Connecting the centrifugal compressor inlet elbow pipe to the inlet end of the device can adjust and guide the air flow vortex distortion generated after passing through the elbow pipe, thereby moderately increasing the inlet attack angle of the blade leading edge to achieve the purpose of weakening the influence of distortion on the inlet flow field structure of the impeller.
