This kind of adjustment method is relatively rough and easily causes the vacuum instability of the steam turbine, which makes it impossible to effectively control the operating speed of the circulating water pump, affects the normal operation of the steam turbine, and makes the power supply unstable and unreliable. In addition, when the steam turbine is in a low-load operation state, it is very easy to reduce the operating efficiency of the circulating water pump, which will increase the energy consumption of thermal power plants and affect the operating benefits of thermal power plants., it will cause the vacuum of the condenser to drop, thereby affecting the normal operation of the steam turbine. During the operation of the steam turbine, the vacuum degree of the condenser is also a very important influencing factor., it is very easy to cause abnormal vibration of the steam turbine. For this reason, through the treatment of grinding and repair welding, the vacuum degree of the condenser is effectively improved, and the Axle For Vehicles Suppliers normal operation of the condenser is ensured, thereby providing a reliable guarantee for the orderly operation of the steam turbine. Circulating water pump failure During the operation of the steam turbine unit, the circulating water pump plays a very important role as an important component. In the thermal control loop, because the protection action cannot be implemented, after the steam turbine is started, the feedwater pump cannot be closed smoothly, resulting in a failure.
