A compressor impeller with regulating function

Abstract

The invention discloses a compressor impeller having a regulatory function. The compressor impeller comprises an impeller body; one side of the impeller body is provided with a rotating shaft hole; the sidewall of the rotating shaft hole is provided with two symmetrically-formed clamping column grooves; each clamping column is slidably installed inside the corresponding clamping column groove; thesides, close to each other, of the two clamping columns both extend into the rotating shaft hole and are each provided with a clamping block in a welding way; a driving shaft positioned inside the rotating shaft hole is arranged between the two clamping columns; the outer side of the driving shaft is provided with two symmetrically-formed clamping grooves; each clamping block is clamped in the corresponding clamping groove; a rotating chamber formed in the impeller body is arranged above the rotating shaft hole and is positioned between the two clamping column grooves. The compressor impellerdisclosed by the invention is high in practicability and convenient to operate, and can be used for fixing driving shafts of different specifications to the impeller body so as to conveniently fix the position of a turn plate and further fix the position of each clamping column, and thus the driving shaft can be installed on the impeller body more stably.

Description

technical field [0001] The invention relates to the technical field of compressor impellers, in particular to a compressor impeller with an adjustment function. Background technique [0002] Compressor impeller, also known as working wheel, is the only element in the centrifugal compressor that does work on the airflow. The most important part of the rotor is generally composed of discs, wheel covers and blades. The impeller rotates at high speed, the gas is affected by the rotating centrifugal force, and the diffusion flow in the impeller increases the pressure after it passes through the impeller. The patent document with application number 201010624490.4 provides a compressor impeller structure. This structure, comprising a central hub and a plurality of impeller blades extending outwardly from the hub, each of said vanes defining a leading edge, a trailing edge and a root connecting the blades to the hub, wherein at least one of the blades has a variable thickness skin p...

[0002] Compressor impeller, also known as working wheel, is the only element in the centrifugal compressor that does work on the airflow. The most important part of the rotor is generally composed of discs, wheel covers and blades. The impeller rotates at high speed, the gas is affected by the rotating centrifugal force, and the diffusion flow in the impeller increases the pressure after it passes through the impeller. The patent document with application number 201010624490.4 provides a compressor impeller structure. This structure, comprising a central hub and a plurality of impeller blades extending outwardly from the hub, each of said vanes defining a leading edge, a trailing edge and a root connecting the blades to the hub, wherein at least one of the blades has a variable thickness skin provided with a ceramic material Superficially, this structure first addresses issues related to compressor wheel fatigue life and compressor wheel corrosion, the leading edge of the impeller blade, which is exposed at very high speeds to the introduction of large quantities of potentially harmful species and particulate matter, has a relatively thick The protective ceramic coating can protect the compressor impeller adequately, but the impeller in this structure is not suitable for drive shafts of different specifications, which affects the use of compressor impellers on drive shafts of different specifications, so we propose A compressor impeller with adjustment function is used to solve the above problems
