Abstract

The invention belongs to the technical field of diffuser processing, and particularly relates to a corrosion-resistant diffuser. The diffuser comprises a diffuser body, wherein an anode acidizing treatment layer is arranged on the surface of the diffuser body. A processing method comprises the following steps of plane milling, specifically, an aluminum plate is pressed through a pressing plate, through holes and counterbores are punched in a circumference, screws are driven in, then the pressing plate is loosened, and the plane of the aluminum plate is milled by using a milling cutter. According to the corrosion-resistant diffuser processing method, because the metal aluminum material is used as a base plate of the made diffuser, the made diffuser has good corrosion resistance; because thesurface of the metal aluminum plate is subjected to anodic oxidation treatment in the processing treatment of the metal aluminum plate, and compared with a common stainless steel plate, the diffuserhas better corrosion resistance, has the bright and attractive surface, is unlikely to fade and is wide in application range and long in service life. The corrosion-resistant diffuser processing method is simple in process and convenient for operation; the made diffuser is high in overall precision, good in using effect and improved in efficiency; and the processing cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of diffuser processing, and in particular relates to a method for processing a corrosion-resistant diffuser. Background technique [0002] The function of the diffuser is to convert the dynamic pressure of the fan into static pressure, so that the speed is reduced and the pressure is increased. The diffuser is divided into two categories: vane diffuser and vaneless diffuser. The difference in area converts velocity energy into pressure energy. The vane diffuser is nothing more than restricting the flow direction of the airflow through the shape of the vane, thereby shortening the overall structural size of the diffuser channel. In axial flow compressors, vaneless diffusers are generally used after the final stage to recover the velocity energy of the airflow. Of course, a similar diffuser section will also be used at the outlet of the turboexpander. [0003] In recent years, steam compressors and aeration...
