Abstract: Aiming at mechanical wearing, ageing and speed regulation delay problems of hydrodynamic torque converter in ammonia pump, this paper raised to use the medium voltage variable frequency speed regulation device to replace the existing hydrodynamic torque converter speed regulation method, giving the configuration and control principle of variable frequency speed regulation system. Actual running result shows that the rebuilt system overcomes defects of traditional device, to have ensured continuity of production, to have improved equipment reliability, with operation cost saved and plentiful economic benefits.
Key words: medium voltage variable frequency speed regulation device; ammonia pump; hydrodynamic torque converter
