| 摘 要： | 为了说明单级增压系统与二级增压系统总压缩功的情况,在P-V图上分别对两种系统的增压过程进行了理论分析。在专门的二级增压系统性能试验台架上进行了试验研究,并将试验结果与单级增压系统的试验结果进行了对比分析。结果表明,由于中冷器及管道损失,二级增压系统的总压缩功往往大于单级增压系统的总压缩功。只有当总压比较高、中冷器温降足够大、中冷器及管道的压降损失较小,且高低两级压气机都处于高效率工作区的情况下,二级增压系统才能充分发挥其优势。

| Abstract: | To discuss the total compressing power of the single stage turbocharing system and the two-stage turbocharging system,the compressing processes of two systems are theoretically analyzed on the P-V diagram.The test is carried on a special two-stage turbocharging test bench,and the test result of the two-stage system is compared with that of the single stage system.The results indicate that,the total compression power of the two-stage turbocharging system maybe larger than that of the single stage system beca... |
