裂解P-300A/S泵机械密封的改造

Renovation of Mechanical Seal of P-300 A/S Cracking Pump

针对乙烯裂解装置P-300A/S悬臂式离心泵国产化后,机械密封频繁泄漏失效,导致机械密封寿命短的问题,对机械密封失效因素进行了具体的分析,找到了导致机械密封泄漏的主要原因,提出并采取了相应的改造措施,从根本上解决了机封泄漏问题,从而保证设备的长周期运行,节约成本,提高了经济效益。

Aiming at the localization of the ethylene cracking unit of P-300A/S cantilever centrifugal pump, mechanical seal failure caused frequent leakage, short life of mechanical seal, mechanical seal failure factors are analyzed, find the main reason which leads to mechanical seal leakage, puts forward and take the corresponding improvement measure, fundamentally solves the sealing machine leakage problems, so as to ensure long term operation, the equipment cost savings, improve economic benefit.
