Abstract
The present disclosure provides a compressor rotor, a compressor and a refrigerant circulation system. The compressor rotor includes: a motor rotor including a plurality of rotor sections, a locking rod, a compression unit rotating part and a locking member. The rotor sections are fixedly connected in an axial direction and are provided with an axial through hole and the locking rod penetrates through the axial through hole. The compression unit rotating part is located at the end part of the motor rotor and is connected to the locking rod. The locking member is configured to lock the compression unit rotating part on the locking rod. The locking rod, the compression unit rotating part and the locking member form a pressing structure which applies a pressure toward an axial inner side to the motor rotor.
