Abstract
A motor direct-drive high-speed centrifugal drum pressure fan comprises a motor and a compressor, and is characterized in that the motor and the compressor share the same main shaft, and the impeller of the compressor is mounted on the main shaft. In the utility model, the motor and the compressor share the same main shaft, the impeller of the compressor is directly mounted on the main shaft, a seal device is arranged between a motor bearing and the impeller of the compressor, and the motor is a variable frequency motor with a PLC (Programmable Logic Controller). Compared with the traditional centrifugal drum pressure fan, the motor direct-drive high-speed centrifugal drum pressure fan is simpler in structure and easier to install due to the lack of a speed increasing box. Moreover, the drum pressure fan can effectively prevent lubricant from contaminating the working medium, thereby greatly expanding the working condition scope in which the drum pressure fan is applicable. The drum pressure fan is simple and compact in overall structure, convenient to maintain and high in operating efficiency.
