Turbine speed control system
Thread Content
Who has the English-Chinese translation for the 505E operation interface in the speed control system? It would be great if someone could explain the specific operating procedures.
There are many types of turbine speed control systems available today. But their basic functions are similar; they all include special warm-up procedures, cold and hot start procedures, as well as mechanical and electronic trip testing procedures. As long as you thoroughly understand the basic principles of turbine speed control, it’s similar regardless of the system; it’s easy to get started, just like learning a new software – it’s a matter of gaining proficiency through practice. The most important thing is to thoroughly understand the speed control theory of steam turbines.
http://bbs.hcbbs.com/thread-332287-1-1.html The turbine governor converts changes in the turbine’s speed into changes in oil pressure. When the turbine is operating stably, there is a proportional relationship between changes in speed and changes in oil pressure. This oil pressure, which directly reflects the speed of the turbine, is known as the primary oil pressure, and it is used as the control signal. Since the change in primary oil pressure generated by the governor in response to changes in rotational speed is very small, a pressure converter is typically used for the first stage of amplification, while the throttle valve serves as the second stage of amplification to produce a higher-pressure oil stream that drives the hydraulic actuator. This actuator, together with the control valve, functions as an actuating mechanism to adjust the steam flow entering the turbine, thereby achieving the goal of regulating the turbine’s rotational speed
The 505 governor is the control system for the ammonia compressor here. Our ammonia compressor starts semi-automatically. The keys that are used frequently include: STOP, CLEAR, RESET, RUN, SPEED, the up and down scroll keys, as well as remote and local indicators. Its acceleration mode is fixed. As long as you enter the command, it will be completed automatically, with no need for any control during this process.
It is regulated by secondary oil pressure; this secondary oil pressure exerts a force that increases the degree of opening of the valve. In other words, the magnitude of the secondary oil pressure determines how much the valve opens
There are many turbine speed control systems available today; their basic principles are all the same – the differences lie in the user interfaces, as well as in functional improvements and the language used in those interfaces. Understanding the basic principles makes it easy to get started.
