  • Publication number: 20190242744
    Abstract: The present invention provides an online diagnostic/prognostic system, for a rotation device, which does not require a diagnostic apparatus to be transferred and enables easy transmission of waveform data to a remote site. To this end, the present invention comprises: a vibration sensor mounted on a rotation device; a data analyzing unit connected to the vibration sensor and for extracting valid data, which is required for the diagnosis of the rotation device, from data obtained from the vibration sensor; and a diagnostic/prognostic server for diagnosing for abnormalities in the rotation device by means of comparing the valid data and prestored data. Therefore, the present invention does not require an apparatus for measuring vibrations to be transferred and enables transmission of waveform data to a remote cite, thereby enabling more efficient diagnosis for a rotation device and preventing abnormalities in the rotation device.

  • Publication number: 20190195249
    Abstract: Method for diagnosing a pneumatic control valve by using a positioner model includes: establishing relational expression for outputting valve stem displacement according to control pressure, the relational expression including parameters for the characteristics of a positioner, an actuator, and a valve, determining initial parameter value by adjusting the values of the parameters until the difference between a measured value for a normal operation of the pneumatic control valve and output value obtained by the relational expression is smaller than predetermined error limit, determining diagnostic parameter value by adjusting the values of the parameters until the difference between a measured value for a diagnostic operation of the pneumatic control valve and an output value obtained by the relational expression is smaller than a predetermined error limit, and comparing the initial parameter value and the diagnostic parameter value so as to determine whether the pneumatic control valve has abnormality.

  • Publication number: 20190188345
    Abstract: The present invention provides a method for diagnosing a rotation device by means of a rotor-bearing-foundation model, the method characterized by utilizing the characteristics of a simulation rotor system. To this end, the present invention comprises the steps of: simulating a rotation device as a rotor system; forming a mathematical model for the rotor system; estimating the state of the rotation device by means of the mathematical model and a vibration measurement value of the rotation device; and diagnosing for abnormalities in the rotation device from the changes in an estimated value. Therefore, since a rotation device is diagnosed for abnormalities by means of forming a mathematical model for a rotor system, the present invention enables more accurate diagnosis of the rotation device.

  • Patent number: 10249394
    Abstract: The present invention relates to a passive nitrogen injecting device for a nuclear reactor coolant pump, the device comprising: a nitrogen supply unit for supplying nitrogen; a pressure control valve for controlling the supply of nitrogen from the nitrogen supply unit according to pressure; an accumulator for filling the nitrogen supplied through the pressure control valve at a set pressure, and supplying the filled nitrogen in the event that an accident involving coolant loss occurs; and an isolation valve for controlling the supply of the nitrogen from the accumulator into a seal housing of a nuclear reactor coolant pump. The present invention uses an accumulator so as to be able to supply nitrogen by using the pressure in the accumulator without the supply of external power in the event of an accident involving coolant loss, and therefore has the effect of being able to improve safety.
