摘　　要：介绍了煤气风机采用液力耦合器和电磁阀相结合自动控制和调整500 kW煤气风机转速,此方法以初冷器前吸力值的大小,通过变送器反馈给电磁阀和液力耦合器,实现500 kW煤气风机的吸、压力自动调节。不但比改造前传统的"大、小循环"方便、稳定,而且节能、环保、低噪音。The use of hydraulic coupling gas blower and solenoid valve combination gas 500 kW automatic control and adjust fan speed was introduced. This method to the beginning of cooler the size of the value before the suction through the transmitter back to the solenoid valve and hydraulic coupler, implementation of the suction fan 500kW gas pressure automatic adjustment. Not only transform the former than the traditional ＂big -small cycle＂ convenient, stable and energy-saving, environmental protection, low noise.

关 键 词：调节方式 大 小循环 变送器
