水压式端面密封方式是目前中小型水轮机常用的主轴密封机构.因各电站具体的水头、水质存在差异,在机组运行过程中,应根据现场情况合理调整冷却水压力,避免密封胶垫烧损.
水壓式耑麵密封方式是目前中小型水輪機常用的主軸密封機構.因各電站具體的水頭、水質存在差異,在機組運行過程中,應根據現場情況閤理調整冷卻水壓力,避免密封膠墊燒損.

Hydraulic pile end face sealing methods are commonly used at present small and medium-sized turbine main shaft sealing mechanism. Based on the differences between the power station concrete water head, water quality, in the unit operation process, the damage of sealing rubber gasket should be avoided by adjusting cooling water pressure according to site conditions.
