| 摘 要： | 25000 m3/h空分设备配套的RIK90-4型空压机,由于放空阀及其管道的安装标高不合理,导致叶轮清洗水长期积聚在管道内,使放空阀的阀板与阀体生锈卡死,从而使空压机停机过程中的排气压力和排气量不匹配而发生喘振。简介喘振现象和经过,介绍原因分析过程,最后提出预防放空阀及其管道积水进而使放空阀卡死的措施。

| Abstract: | Due to unreasonable installation elevation of vent valve and its pipeline of Model RIK90-4 air compressor necessary for 25000 m3/h air separation plant,impeller washing water is always collected in the pipeline,which results in rust of and seizure between the valve plate and valve body of the vent valve and then results in surge because of unmatched exhaust pressure and exhaust volume of the air compressor during its shutdown.The phenomena and course of the surge are briefed,the cause is analyzed and the me... |
