压缩机高压填料泄漏问题研究

针对储气库高压大排量压缩机运行中出现的高压填料泄漏问题进行调查研究并提出解决方案.首先对填料盒内各环承压密封进行仿真分析,论证了三瓣式填料环易破碎的原因是应力集中问题,提出改用六瓣式填料环的解决方案,消除了应力集中,并进一步改进了六瓣式填料环材质形式,采用PEEK+金属材质组合,提高了外环的强度与韧性;其次通过对填料环...

ON LEAKAGE OF HIGH PRESSURE PACKING IN COMPRESSOR

Aiming at the leakage problem of high pressure packing in the operation of high pressure and large displacement compressor in gas storage,investigation and analysis were carried out,and solutions were put forward.First of all,simulation analysis on the pressure sealof each ring in the packing box was carried out.It was demonstrated that the reason for the vulnerability to breakage of the three petal packing ring was the stress concentration.Asix petal packing ring was proposed to eliminate the stress concentration.The material form of the six petal packing ring was further improved,and the combination of PEEK+metal material was adopted to improve the strength and toughness of the outer ring.Then through dynamic load analysis of the packing ring,it was found that the bursting problem was caused by the viscosity of the lubricating oil.Finally,through analysis of spring binding force,the improvement of increasing spring binding force and adopting solid spring was put forward.After the above improvements,the sealing effect was good in the field test and the packing leakage problem was solved.
