How to adjust the zero point of the speed control valve in Hangzhou Steam Turbines
Thread Content
The turbine of Hangqi has been in operation for over 2 years. The last time it was shut down, the valve position of the indoor speed control valve had been set to 0, yet the gauge on site indicated a certain degree of opening. How can the zero point of the speed control valve be adjusted?
There is an adjustment screw on the throttle; if I remember correctly, it needs to be turned clockwise. (It’s best to follow what’s actual on site – whether clockwise or counter-clockwise, just make sure that the speed control valve is set to zero.)
