摘要:
A balance piston for a compressor is provided. The balance piston may include an annular body and a seal extending from an axial surface of the annular body. The annular body may be configured to be disposed about and coupled with a rotary shaft of the compressor. The seal may be configured to form a sealing engagement with at least one component of the compressor to prevent a flow of a process fluid from an impeller of the compressor to a seal cavity of the compressor.
摘要(中):
提供了一种用于压缩机的平衡活塞。 平衡活塞可以包括环形体和从环形体的轴向表面延伸的密封件。 环形体可以被配置为围绕压缩机的旋转轴设置并与其连接。 密封件可以被配置成与压缩机的至少一个部件形成密封接合,以防止工艺流体从压缩机的叶轮流到压缩机的密封腔。
