Split forming mixed flow turbine

Abstract

The invention discloses a split forming mixed flow turbine. The turbine comprises an outer flow guide cover and an inner flow guide cover, and a plurality of first blades are arranged around the central axis of any one of the inner wall of the outer flow guide cover and the outer wall of the inner flow guide cover, wherein the inner flow guide cover and the outer flow guide cover are arranged in acooperating mode; a flow guide air channel is formed among the first blades, the outer wall of the inner flow guide cover and the inner wall of the outer flow guide cover; and a plurality of second blades are arranged on the outer wall of the outer flow guide cover and around the central axis. The split forming mixed flow turbine has the advantages of being capable of preventing leakage and effectively improving the air supply performance.

Description

technical field [0001] The invention relates to a turbine, in particular to an anti-backflow turbine. Background technique [0002] Existing split turbines generally include an outer shroud and an inner shroud. When the turbine rotates, the air inlet in the center of the turbine will inhale the surrounding air. Under the guidance of the duct, it blows out from the air outlets around the turbine, and sends air outward along the inner wall of the outer cover. Since the outer shroud is also running during work, there must be a certain gap between the outer shroud and the outer shroud, otherwise the outer wall of the outer shroud will rub against the outer shroud, which will affect the operation of the turbine. However, since the air inlet air pressure of the turbine is low and the air outlet air pressure along the wheel is high, the high-pressure airflow on the air outlet side will leak back to the air inlet side through this gap, which will weaken the output of the turbine. ...

Since the outer shroud is also running when it is working, there must be a certain gap between the outer shroud and the outer shroud, otherwise the outer wall of the outer shroud will rub against the outer shroud, affecting the operation of the turbine

However, since the air inlet air pressure of the turbine is low and the air outlet air pressure along the wheel is high, the high-pressure airflow on the air outlet side will leak back to the air inlet side through this gap, which will weaken the output of the turbine. Air pressure and flow affect the performance of the turbine
