密封油真空系统与大机真空系统联通

Vacuum tank in sealing oil system connect to condenser vacuum

由于密封油罗茨真空泵、水环真空泵经长期运行性能变差，出力降低，使真空油箱长期在-70kPa的低真空以下运行，极大影响了氢气纯度；罗茨真空泵、水环真空泵故障逐渐频繁，设备可用率也在降低，为此，经过论证，将密封油真空系统与大机真空系统联通，这样，密封油系统真空泵组可长期停运，既可一定程度上节约厂用电，又可保证设备的稳定运行。

Through long- term performance, the oil -sealed Roots vacuum pump and water ring vacuum pump become poor performance and low output, causing the long - term operation of vacuum tank in the low- 70kPa low vacuum, which greatly affected the hydrogen purity; with the frequent fault for Roots vacuum pump and water ring vacuum pump , equipment availability was reduced, for this, after demon- stration, oil -sealed vacuum system connect to condenser vacuum in steam turbine, in this way, oil - sealed vacuum system can be long -term outage, to a certain extent, this method can save the electricity, and ensure stable operation of the equipment.
