Description

The present invention relates to the technical field of turbine safety operation monitoring, and in particular to a turbine safety operation monitoring device.

If it is found that the ASP pressure is gradually decreasing during operation, this problem is a serious potential danger for the ETS system, and from the perspective of hazard identification, it is a serious potential danger for the equipment that directly affects the safe operation of the machine. When the machine is operating normally, the four AS
The T solenoid valve is energized and closed, thereby closing the fuel oil spill passage on the automatic shutoff (AST) mother pipe, and the hydraulic pressure in all steam valve enforcement mechanism piston bores can be established, the ASP pressure is continuously reduced, and the boiler MFT operates when the ASL < 7 MPa.

Currently, low ASP oil pressure is a serious potential danger for system operation, and the cause of the failure cannot usually be determined directly, so the equipment must be stopped and inspected. In addition, if the temperature in the summer workplace is high and it is difficult to determine the cause, a pressure gauge can be installed behind the solenoid valve to check for internal leakage from the solenoid valve. Through these two pressure gauges, the cause of low ASP pressure can be determined more effectively. Therefore, a turbine safety operation monitoring device is proposed.
