Description

Axial expander

Technical Field

The utility model relates to an axial expander especially relates to an axial expander's guide vane structure.

Background

The fixing mode of the flow guide blade of the axial air inlet expander in the current market mainly comprises a mode of circumferentially increasing a circle of steps, a mode of welding, a mode of increasing a fixing support, a hot sleeve process and the like, and disadvantages of the following modes are introduced respectively:

the guide flow She Piankuang is added with a circle of steps (as shown in fig. 1): the circumferential movement of the blades is limited by the steps, and the airflow is suddenly changed after encountering the steps due to the increase of the steps, so that the pneumatic performance is influenced.

Welding (as shown in fig. 2): the diameter of the existing expander blade is 110mm, the number of the blades is about 20-40, the maximum thickness of the blade is 2-3mm, the welding can face too small blade gap, which is not only inconvenient for welding workers to operate, but also can not weld a circle around the blade, thus causing the problem of low welding strength; the number of blades is large, the welding time is very long, and the cost is very high; in addition, welding cannot guarantee complete consistency of welding seams, and pneumatic performance is also affected.

A fixed bracket is added at the air inlet end (as shown in figure 3): because the fixed support changes the air inlet flow, the air inlet flow deviates from an ideal state, and the overall pneumatic performance is influenced.

Heating a sleeve: the thermal sleeve is mainly realized through the interference magnitude of the blade and the fixed frame; the interference magnitude is small, the fixing force between the blade and the fixed frame is small, and the blade is easy to fall off under the condition of alternating airflow and long-term vibration of a machine, so that the working blade is damaged; the interference magnitude is big, and the fixed power between blade and the fixed frame is big, and the extrusion force that the blade received is big, and the blade has the deformation to influence the flow direction of air current, thereby influence complete machine aerodynamic performance.

In view of this, the utility model discloses it is special.
