Embodiment Construction
[0048] Embodiments of the compressor system oil equalization control method of the present invention, such as figure 2 , Figure 4 shown.
[0049] The oil equalization control method of the compressor system of the present invention comprises the following steps:
[0050] Set up N rotary compressors connected in parallel;
[0051] Start the N1 compressors 1 in the N parallel-connected rotary compressors to run simultaneously;
[0052] Detecting the phase angles of the motor rotors of the N1 compressors;
[0053] Determine whether the phase angles of the motor rotors of the N1 compressors are consistent; if they are consistent, run the routine operation control program to control the operation of the N1 compressors 1; if not, adjust the phase angles of the motor rotors of the N1 compressors so that After the phase angles are consistent, run the routine operation control program to control the operation of the N1 compressors 1;
[0054] N and N1 are integers greater than 1...
