Abstract

The invention belongs to the technical field of diffuser processing, in particular to a corrosion-resistant diffuser, comprising a diffuser body, the surface of the diffuser body has an anodic acid treatment layer, and the processing method includes the following steps: milling a plane: First, the aluminum plate is pressed down with a pressure plate, and the through holes and countersunk holes punched on the circumference are tightened with screws, and then the pressure plate is loosened, and the plane of the aluminum plate is milled with a milling cutter; the diffuser made by the present invention is made of metal aluminum As the base plate, the manufactured diffuser has good corrosion resistance, and the surface of the metal aluminum plate is anodized during processing, which has higher strength and corrosion resistance than ordinary stainless steel plates, and the surface is bright and beautiful, and it is not easy to fade. Wide application range and long service life. The processing method adopted by the present invention has simple steps and is easy to operate. The processed diffuser has high overall precision and good use effect, improves the efficiency of the diffuser, and shortens the processing cycle.

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...
