为防止压缩机在运行中变形,用粉末冶金方法制造了带减压槽的压缩机法兰。将制造法兰的粉末材料装于模腔中,然后,将熔点比粉末材料低的熔渗件置于减压槽位置进行成形;将粉末材料与熔渗件压制成形为法兰;在粉末材料与熔渗件熔点之间的温度下进行烧结,使熔渗件熔化和渗入粉末材料之中。用新方法制造的法兰比用常规方法生产的强度高、密封性好。根据分析,在烧结时,由于熔渗件熔化与渗透到法兰结构中,改进了气密性,增高了强度。
In order to prevent the compressor deformation in operation, with powder metallurgy method to create a compressor flange with vacuum tank. Forming a flanged powder material in a mold cavity, then placing an infiltration member having a melting point lower than that of the powder material at a position of the decompression groove to press the powder material and the infiltration member into a flange, And infiltration melting point melting temperature between the sintering, melting infiltration pieces infiltrated into the powder material. Flanges made by the new method have higher strength and better sealing than conventional methods. According to the analysis, at the time of sintering, since the infiltration element melted and infiltrated into the flange structure, the airtightness was improved and the strength was increased.
