Description

The present invention relates to a steam trap management system for managing the state of a steam trap.

In a plant equipped with a steam piping system, condensate (drain) may occur in the piping system due to heat exchange or heat dissipation. If this condensate stays in the piping system, it will cause a decrease in operating efficiency. Therefore, in general, a steam trap should be installed in the appropriate place in the piping system, and the condensate should be discharged to the outside of the piping system by this steam trap. I have to.

If the sealing performance of the steam trap is impaired due to deterioration over time or malfunction, steam in the steam piping system leaks to the outside through the steam trap, resulting in unnecessary steam loss. Therefore, the work of checking the state of the steam trap is performed regularly.

A fixed measuring device is attached to the steam trap installed in the main piping system in the plant. The measuring device periodically measures the temperature and vibration of the steam trap, such as once a day, and transmits the measurement data showing the measurement result to the on-premises in-house server. The in-house server diagnoses the state of the steam trap based on the received measurement data, and manages diagnostic data indicating the result of the diagnosis.

Fixed measuring devices are not installed in steam traps installed in non-major piping systems in the plant. The state of the steam trap is diagnosed by a periodic inspection work such as once a year using a portable measuring device and a diagnostic device by an operator. The measuring device measures the temperature and vibration of the steam trap, and transmits measurement data indicating the measurement result to the diagnostic device. The diagnostic device diagnoses the state of the steam trap based on the received measurement data. The diagnostic data showing the result of the diagnosis is managed by the terminal device (for example, PC) of the worker who performed the inspection work.

The following Patent Document 1 discloses a measuring device and a diagnostic device for diagnosing the state of a steam trap. The measuring device is a portable measuring device, the diagnostic device is a tablet terminal, a notebook computer, or the like, and the measuring device and the diagnostic device can communicate wirelessly with each other. The measuring device includes a temperature sensor that measures the surface temperature of each steam trap, a vibration sensor that measures the vibration intensity of each steam trap, a storage unit that stores the temperature sensor and the measurement data output from the vibration sensor, and the measurement thereof. It includes a communication unit that transmits data to the diagnostic device and a display unit. The diagnostic device diagnoses the state (normal or abnormal) of each steam trap based on the measurement data received from the measuring device, and transmits diagnostic data indicating the result of the diagnosis to the measuring device. The measuring device displays the diagnosis result for each steam trap on the display unit based on the diagnostic data received from the diagnostic device.

In addition, since thousands to tens of thousands of steam traps may be installed in a large plant, the management ledger is used as management information for managing the status of such a huge number of steam traps. Sometimes.

The following Patent Document 2 describes identification information such as a serial number (trap ID), attribute information such as a manufacturer name and model, and operation information such as working pressure and set temperature for each of all steam traps to be managed. , A management ledger that describes the diagnosis results of past periodic inspections is disclosed.

FIG. 7 is a diagram showing an example of the management ledger 200. In the management ledger 200, type information I1, identification information I2, attribute information I3, operation information I4, and diagnosis result information I5 are described for each of all steam traps.

The type information I1 is described as "fixed" when the measuring device is attached to the steam trap (that is, the steam trap to be measured by the fixed measuring device). Further, the type information I1 is described as "portable" when the measuring device is not attached to the steam trap (that is, when the steam trap is the target of diagnosis by the portable diagnostic device). The identification information I2 is a trap number, and in this example, the reference code shown in FIG. 1 is used. The trap number is a unique identification number (ID) assigned to each steam trap. The attribute information I3 includes the manufacturer name and model name of each steam trap. However, the attribute information I3 may further include product number information that is more detailed than the model name. The operation information I4 includes the working pressure and the set temperature.

The control unit 72 stores the management ledger 200 received by the communication unit 71 in the storage unit 73 (step S3).

<Measurement with a fixed measuring device>
The measuring devices 11 to 13, 21 to 23 periodically measure the temperature and vibration of the steam traps ST11 to ST13 and ST21 to ST23 once a day or the like (step S4). Further, the measuring devices 11 to 13, 21 to 23 transmit the measurement data indicating the measurement result to the server device 6 via the repeaters 1, 2, the master unit 4, and the communication network 7 (step S5). ..

The communication unit 71 of the server device 6 receives the measurement data transmitted from the measuring devices 11 to 13, 21 to 23. The acquisition unit 81 acquires the measurement data received by the communication unit 71 from the communication unit 71. The diagnosis unit 82 diagnoses the states of the steam traps ST11 to ST13 and ST21 to ST23 based on the measurement data acquired by the acquisition unit 81, and creates the diagnosis result information I5 of the steam traps ST11 to ST13 and ST21 to ST23. (Step S6).

The management ledger update unit 83 updates the management ledger 200 stored in the storage unit 73 based on the diagnosis result information I5 created by the diagnosis unit 82 (step S7). Specifically, the management ledger updating unit 83 adds the diagnosis result information I5 created by the diagnosis unit 82 to the corresponding portion specified by the identification information I2 in the management ledger 200 stored in the storage unit 73. By adding the diagnosis result information I5 to the corresponding part of the management ledger 200, the diagnosis result information I5 of each steam trap ST11 to ST13 and ST21 to ST23 becomes the identification information I2 of each steam trap ST11 to ST13 and ST21 to ST23. It will be associated and stored in the storage unit 73.

<Preparation for regular inspection>
Before carrying out this periodic inspection, the operator sends the latest management ledger 200 to the server device 6 by transmitting a ledger request signal from the data processing device 5 to the server device 6 via the communication network 7. Request (step S8).

Upon receiving the ledger request signal, the server device 6 transmits the latest management ledger 200 read from the storage unit 73 to the data processing device 5 via the communication network 7 (step S9).

In the data processing device 5, the communication unit 66 receives the management ledger 200 transmitted from the server device 6. The control unit 62 stores the management ledger 200 received by the communication unit 66 in the storage unit 65 (step S10). Further, the control unit 62 inputs the management ledger 200 received by the communication unit 66 into the communication unit 61. The communication unit 61 transmits the input management ledger 200 to the diagnostic device 3 (step S11). In the diagnostic device 3, the communication unit 56 receives the management ledger 200 transmitted from the data processing device 5. The control unit 52 stores the management ledger 200 received by the communication unit 56 in the storage unit 55 (step S12).

<Inspection work>
The periodic inspection worker carries the diagnostic device 3 (and the data processing device 5 if permitted) and moves in the plant, so that the diagnostic device 3 measures each steam trap ST31 to ST33 in order. (Step S13).

At that time, a request signal is input from the operation unit 53 to the control unit 52 in response to a switch operation or the like by the operator, so that the control unit 52 displays the management ledger 200 stored in the storage unit 55 in advance in preparation. Display on. As a result, the worker can recognize the identification information I2 and the attribute information I3 of the steam traps ST31 to ST33, which are the targets of the periodic inspection work. When the worker carries the data processing device 5, the management ledger 200 may be displayed on the display unit 64 of the data processing device 5. Since the display unit 64 usually has a larger screen than the display unit 54, displaying the management ledger 200 on the display unit 64 improves visibility by the operator.

The worker moves to the installation location of the steam trap, which is the target of this measurement. Further, the operator selects one steam trap to be measured this time from the steam traps ST31 to ST33 to be the target of the periodic inspection work by operating the switch of the operation unit 53. As a result, the steam trap selection information is input from the operation unit 53 to the control unit 52.

Next, the operator presses the probe (not shown) of the diagnostic device 3 against the steam trap to be measured. As a result, measurement data (temperature data and vibration data) are input from the measurement unit 51 to the control unit 52. The diagnosis unit 59 diagnoses the state of the steam trap to be measured based on the measurement data input from the measurement unit 51 (step S14).

The control unit 52 inputs diagnostic data indicating the result of the diagnosis by the diagnostic unit 59 to the display unit 54. As a result, the diagnosis result regarding the steam trap to be measured is displayed on the display unit 54.

Further, the control unit 52 creates the diagnosis result information I5 (diagnosis date and diagnosis result) based on the diagnosis data, and stores the diagnosis result information I5 in the management ledger 200 stored in the storage unit 55. The management ledger 200 is updated by adding to the corresponding part specified by (step S15). By adding the diagnosis result information I5 to the corresponding portion of the management ledger 200, the diagnosis result information I5 of each steam trap ST31 to ST33 is associated with the identification information I2 of each steam trap ST31 to ST33 and is stored in the storage unit 55. It will be remembered.

Further, the control unit 52 inputs the diagnosis result information I5 of each steam trap ST31 to ST33 to the communication unit 56. The communication unit 56 transmits the input diagnosis result information I5 to the data processing device 5 (step S16).

The communication unit 61 of the data processing device 5 receives the diagnosis result information I5 transmitted from the communication unit 56.

The acquisition unit 67 acquires the diagnosis result information I5 received from the diagnosis device 3 by the communication unit 61 from the communication unit 61.

The control unit 62 updates the management ledger 200 stored in the storage unit 65 based on the diagnosis result information I5 acquired by the acquisition unit 67 (step S17). Specifically, the control unit 62 adds the diagnosis result information I5 acquired by the acquisition unit 67 to the corresponding portion specified by the identification information I2 in the management ledger 200 stored in the storage unit 65. By adding the diagnosis result information I5 to the corresponding portion of the management ledger 200, the diagnosis result information I5 of each steam trap ST31 to ST33 is associated with the identification information I2 of each steam trap ST31 to ST33 and is stored in the storage unit 65. It will be remembered.

Further, the control unit 62 inputs the diagnosis result information I5 acquired by the acquisition unit 67 to the communication unit 66. The communication unit 66 transmits the input diagnosis result information I5 to the server device 6 via the communication network 7 (step S18).

The communication unit 71 of the server device 6 receives the diagnosis result information I5 transmitted from the communication unit 66.

The acquisition unit 81 acquires the diagnosis result information I5 received from the data processing device 5 by the communication unit 71 from the communication unit 71.

The management ledger updating unit 83 updates the management ledger 200 stored in the storage unit 73 based on the diagnosis result information I5 acquired by the acquisition unit 81 (step S19). Specifically, the management ledger updating unit 83 adds the diagnosis result information I5 acquired by the acquisition unit 81 to the corresponding portion specified by the identification information I2 in the management ledger 200 stored in the storage unit 73. By adding the diagnosis result information I5 to the corresponding portion of the management ledger 200, the diagnosis result information I5 of each steam trap ST31 to ST33 is associated with the identification information I2 of each steam trap ST31 to ST33 and is stored in the storage unit 73. It will be remembered.

FIG. 8 is a diagram showing an example of the management ledger 200. The addition of the diagnosis result information I5 has been completed for all the steam traps ST11 to ST13, ST21 to ST23, and ST31 to ST33 managed by the management ledger 200. As a result, the update process of the management ledger 200 accompanying this periodic inspection is completed. By executing the same update process every time the periodic inspection is performed, information on the periodic inspection performed in the past is accumulated in the management ledger 200 and managed by the server device 6.

The analysis unit 84 executes various analysis processes based on the management ledger 200 for which the update process has been completed, and stores the analysis data 92 obtained by the analysis process in the storage unit 73 (step S20). For example, the analysis unit 84 has an abnormal diagnosis result (steam leakage, drain discharge failure, or blockage) from all the steam traps ST11 to ST13, ST21 to ST23, and ST31 to ST33 managed by the management ledger 200. Create a bad trap list by listing certain steam traps. Further, the analysis unit 84 calculates the defect rate as the ratio of the total number of steam traps whose diagnosis results are abnormal to the total number of steam traps managed by the management ledger 200. Further, the analysis unit 84 calculates the total leakage amount and the loss amount due to the total leakage amount of each steam trap in which the steam leakage has occurred. Further, when long-term information for several years or more is accumulated in the management ledger 200, the analysis unit 84 aggregates the time-series transitions of these analysis results, and the aggregated result is timed. Output in table or graph format as series data. As a result, the plant manager or the like can grasp the progress of the aged deterioration of the steam trap.
