DA350—61离心压缩机广泛地用于我国化工、冶金企业中,是3200 Nm~3/h、3350Nm~3/h、6000 Nm~3/h等空分设备的原料空压机,该机的性能直接影响着空分设备的产品和能耗。由于原机设计温度较低(t_(in)=20℃),而实际运行气温偏高,所以,一般都达不到设计流量,特别是夏季气温高达30～35℃时,流量 DA350-61 centrifugal compressor is widely used in China’s chemical industry, metallurgical enterprises, is 3200 Nm ~ 3 / h, 3350Nm ~ 3 / h, 6000 Nm ~ 3 / h and other air separation plant raw materials air compressor, the aircraft’s Performance directly affects the air separation plant products and energy consumption. As the original design temperature is low (t_ (in) = 20 ℃), while the actual operating temperature is high, so generally can not reach the design flow, especially in summer temperatures as high as 30 ~ 35 ℃, the flow
