| 摘 要： | 干气密封是一种用于高速旋转设备的非接触式密封。近年来随着技术发展,其制造成本降低,开始在低速离心泵上应用。液化石油气(简称LPG)装车泵因压力瞬变和环境影响而工况恶劣,造成该类泵密封使用寿命短,液化气泄漏严重。干气密封的应用彻底改变了装车泵的运行状况,同时大大改善了现场环境。

| Abstract: | The dry gas seal is non-contact seal used for high speed rotation equipment. Along with the technical progress its fabrication cost is reduced and begins to be used for low speed centrifugal pump. The seal life of LPG loading pump is short because of instant changes of pressure severe operating cases caused by and environmental impact. Thus it causes serious leakage of LPG. The dry gas seal thoroughly changed the operating conditions of LPG pump and improved significantly the site environment. |
