| 摘 要： | 龙滩水电厂水轮机调速系统的液压油泵组由工作泵和增加泵组成，工作油泵选用了常规的定值启动方式，而增压泵选择了连续运行方式，通过液压感压阀实现增压泵负载、空载的状态切换。向压油罐补油或向集油槽排油。控制状态切换的核心设备采用了ALSTOM公司生产的液压感压阀，文章主要对感压阀结构及工作原理进行介绍，供同类水电厂及设计单位参考。

| Abstract: | The hydraulic oil pump group of turbine speed governing system of Longtan hydropower station is com- posed of working pump and booster pump. The working pump adopts the conventional constant startup mode, howev- er, the booster pump adopts the continuous operation mode and switches between load and no-load states to recharge oil to the pressure tank or discharge oil to the oil collector by using of hydraulic pressure sensing valve produced by ALSTOM. The paper makes an introduction to the structure and working principle of the pressure sensing valve, which can be well referenced by similar projects. |
