我公司塑料厂空压站的两台DL160-9离心式压缩机是齐鲁30万吨乙烯装置公用工程的关键设备,用于向塑料、烯烃和储运厂等生产装置供应仪表和工业动力用风.该机四级叶轮呈H型对称布置,一、二级共轴,采用半开式径向叶轮,材料为锻铝(LD10).转速为19 191r/min;三、四级共轴,采用后弯型闭式叶轮,材料为35CrMoV,转速为23 303r/min,排气量为160m~3/min.该机组自1993年3月运行以来,一、二级导风轮叶片多次发生断裂,导致工业风及仪表风压力偏低.一、导风轮叶片断裂的原因该机组自投用以来,导风轮叶片共断裂八次,且均具有相同特征:断裂位置都在叶片根部的前缘点(入口)和
The two DL160-9 centrifugal compressors of the air compressor station of our company are the key equipment for the common project of Qilu 300,000 T ethylene plant for the supply of instruments and industrial power to the production facilities of plastics, olefins, storage and transportation plants, etc. The aircraft four-stage impeller was H-symmetrical arrangement, a, two coaxial, half-open radial impeller, the material is forged aluminum (LD10) speed of 19 191r / min; three or four coaxial, using After the curved closed impeller, the material is 35CrMoV, speed of 23 303r / min, displacement of 160m ~ 3 / min. The unit since March 1993 operation, the first and second wind deflector blades repeatedly rupture , Resulting in low wind pressure of the industrial wind and instrument I. I. The reason of the rupture of the guide vane Since the unit was put into operation, the guide vane has a total of eight faults, and all have the same characteristics: the rupture position is at the front of the blade root Edge (entrance) and
