汽轮机旁路液压控制系统
Turbine Bypass Hydraulic Pressure Control System
 

 

旁路液压控制系统(简称液压旁路)具有驱动力强、响应快、动作平稳的特点,广泛应用于大容量、高参数的汽轮发电机组中。

Bypass hydraulic pressure control system (abbreviated as hydraulic bypass) owns the characteristics of high driving force, quick response and stable operation and is widely used for big volume and great parameter turbine.

我公司长期为旁路阀门的供应商配套供应旁路液压控制系统,同时为电厂提供旁路液压控制系统的改造。

Our company is always supplying bypass hydraulic control system for suppliers of bypass valve and the reforming service for factories.

 

旁路液压控制系统组成:

Element of bypass hydraulic control system:

汽轮机旁路液压控制系统主要包括:供油装置、旁路阀门液压执行机构、油管路及附件。

Turbine bypass hydraulic control system mainly consists of oil supply device, bypass valve hydraulic actuator, oil line and accessories.

供油装置:

Oil supply device:

旁路液压控制系统的供油装置为旁路阀门液压执行机构提供压力油,并具有压力、温度、液位的报警及保护,同时带有抗燃油的处理装置,能实现抗燃油的过滤和再生处理。

The oil supply device of bypass hydraulic control system supplies pressure oil to bypass valve hydraulic actuator, and it can alarm and protect pressure, temperature and level. Attached with disposing device for fire resistant oil, it also can filter out and regenerate oil.

液压执行机构Hydraulic actuator

液压执行机构与旁路阀门直接相连,用于驱动旁路阀门动作。根据阀门的控制方式,可分为伺服型执行机构和开关型执行机构。液压执行机构包括:高旁减温减压阀执行机构、低旁减温减压阀执行机构、高旁喷水阀执行机构、低旁喷水阀执行机构、高旁喷水隔离阀执行机构、低旁喷水隔离阀执行机构。

Hydraulic actuator is directly connected with bypass valve to make bypass valve operate. According to valve’s control mode, it is divided into servo actuator and switch actuator. Hydraulic actuator includes HP bypass temperature & pressure reducing actuator, LP bypass temperature & pressure reducing actuator, HP bypass spray water actuator, LP bypass spray water actuator, HP bypass spray water isolation valve actuator, LP bypass spray water isolation valve actuator.
