| 摘 要： | 本文简介了 WJ5A压气机的改型设计,对比了该压气机改型前后的试验性能。试验表明:该压气机改型后性能得到了较大的提高。在相对折合转速 ηnp1 =1.00的条件下,其最大效率η*kmax增加3.6;nnp1 =0.70～0.90时,η*kmax增加15%以上。在各转速下,压比和流量均有少许变化。

| Abstract: | WJ5A compressor has been modified.The performance data obtained in testing prior to and after the modification of the compressor are compared.Test results indicate that the performance of the modified compressor is greatly improved.In the case of the relative corrected speed ηnp1 =1.0,the maximum isentropic efficiency of the modified compressor ηkmax is increased by 3 6%.When ηnp1 =0 70～0 90,η*kmaxis increased by over 15%.The pressure ratio and the mass flow are changed only a little at all speeds.When ηnp1 >1 0,there is no evident variation in the compressor performance. |
