505 E governor in the U-GB151 the CO_2 compressor applications

ChuanHua Co., LTD of urea fertilizer plant 2 for 2460 T/large chemical fertilizer unit of urea, the CO2 compressor from Japan mitsubishi is used 3 V-7 B type two cylinder four period of compressor, the steam extraction steam injection condensing turbine driving. The turbine speed control by 505 E controller implementation, and combined with ProTech 203 realize the two levels of overspeed protection compressor. Woodward 505 E digital controller are suited for an adjustable pure steam extraction, take fill up with pure steam turbine or type of control, can field programming configuration, make the standard design to be applicable to all kinds of different control occasion. This paper introduces the 505 E controller in the U-GB151 the CO2 compressor of the speed control, and the application examples speed regulation system failures, to carry on the analysis excluded.
