COOLING AIR DUCT STRUCTURE OF COOLING STATOR FOR CENTRIFUGAL COMPRESSOR

摘要

A cooling air duct structure of a cooling stator for a centrifugal compressor, which relates to the technical field of air compressors. The structure includes a casing, a motor support, a rotor, a stator, a first cooling air duct, a second cooling air duct, a connecting plate, and nuts, wherein the stator is located inside the casing, the rotor is located in the middle of the inner side of the stator, both the first cooling air duct and the second cooling air duct are semi-circular members, the first cooling air channel and the second cooling air channel are wrapped on the outside of the casing, and the first cooling air duct and the second cooling air duct are connected and locked through nuts, the first cooling air duct and the second cooling air duct are circumferentially locked through an inner positioning pin, the motor support is installed at the bottom of the casing, has a simple structure, convenient installation and disassembly, and can effectively solve the problem of heat dissipation inside the motor and increase the service life of the motor at the same time.
