Description

[Technical field]

[0001] The present invention relates to a system and method for monitoring vibrations occurring in rotating machines such as pumps, fans, motors and compressors. [Background technology]

[0002] When rotating machines such as pumps, fans, electric motors, and compressors are operated, vibrations are generated in the rotating machines due to mechanical actions (e.g., rotation, sliding, etc.) of parts arranged in the rotating machines. Therefore, inspection of rotating machines usually includes monitoring of vibrations. Users of rotating machines periodically measure the vibrations generated in the rotating machines and monitor the measured values ​​and changes in the measured values ​​over time to determine the occurrence of malfunctions (abnormalities) and the need for maintenance.

[0003] A handheld vibrometer is generally used to monitor vibrations occurring in rotating machinery. More specifically, an inspector measures vibration by pressing the handheld vibrometer against multiple measurement points on the rotating machinery. In this case, the measurement points to which the handheld vibrometer is pressed change every time a measurement is made, and the measurement data also varies depending on the inspector's experience and skill. For this reason, rotating machinery with vibration sensors pre-installed at designated locations is becoming more common in order to improve the reliability of vibration measurement data. By permanently installing vibration sensors at designated locations on rotating machinery, highly reliable vibration measurement data can be obtained at any time. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6867220 Summary of the Invention [Problem to be solved by the invention]

[0005] In order to obtain appropriate vibration data, it is necessary to install the vibration sensor in an appropriate installation position. For example, in the case of a rotating machine having a load side bearing and an anti-load side bearing, an abnormality in the load side bearing may not be detected by a vibration sensor installed only near the anti-load side bearing. Therefore, depending on the type of rotating machine, it is necessary to install the vibration sensor near the load side bearing and near the anti-load side bearing.

[0006] Furthermore, accurate vibration data cannot be obtained unless the installation direction of the vibration sensor is aligned with an appropriate direction according to the installation position of the vibration sensor. For example, in the case of a vibration sensor capable of measuring vibrations in three axial directions, axial, radial, and horizontal directions of a rotating shaft, the vibration sensor must be installed with the measurement directions of these three axes aligned with the appropriate directions relative to the rotating shaft.

[0007] However, there are many types of rotating machines, and the appropriate installation position of the vibration sensor varies for each rotating machine. Furthermore, the appropriate installation direction of the vibration sensor varies for each installation position. Therefore, it is difficult for a user who is unfamiliar with vibration sensors and rotating machines to install the vibration sensor in the appropriate installation position and orientation of the rotating machine. In particular, when installing a vibration sensor on an existing rotating machine, there is a risk that the vibration sensor will be installed in the wrong installation position and direction.

[0008] Therefore, an object of the present invention is to provide a vibration monitoring system for a rotating machine, and a vibration monitoring method for a rotating machine, which are capable of installing a vibration sensor in an appropriate installation position and in an appropriate installation direction to obtain accurate vibration data. [Means for solving the problem]

[0009] In one aspect, a vibration monitoring system for a rotating machine is provided, comprising at least one rotating machine, at least one vibration sensor installed on the rotating machine, and a monitoring device that monitors the measurement values ​​of the vibration sensor, the monitoring device comprising a display that displays sensor installation information of the vibration sensor, and a processing device that processes the sensor installation information displayed on the display, the sensor installation information including type image data that represents, as an image, the type of the rotating machine, model image data that represents, as an image, the model of the rotating machine associated with the type of the rotating machine, installation position data that represents, as an image, a recommended installation position of the vibration sensor associated with the model of the rotating machine, and installation direction data that represents, as an image, an appropriate installation direction of the vibration sensor associated with the recommended installation position, and the processing device displays, on the display, each of the type image data, the model image data, and the installation position data so that a user can select them.

[0010] In one aspect, the processing device causes a display to display the measurement value of the vibration sensor together with the installation position data associated with the vibration sensor. In one aspect, the processing device checks the installation state of the vibration sensor based on the measurement value of the vibration sensor. In one aspect, the processing unit compares the vibration sensor measurements to predetermined thresholds to determine faults and / or the need for maintenance of the rotating machinery.

[0011] In one aspect, a method for monitoring vibration of a rotating machine is provided, in which type image data representing the type of rotating machine as an image, model image data representing the model of the rotating machine associated with the type of the rotating machine as an image, installation position data representing the recommended installation position of the vibration sensor associated with the model of the rotating machine as an image, and installation direction data representing the appropriate installation direction of the vibration sensor associated with the recommended installation position are each displayed on a display of a monitoring device capable of displaying the measurement values ​​of the vibration sensor so that a user can select them.

[0012] In one aspect, the measurement value of the vibration sensor is displayed on a display together with the installation position data associated with the vibration sensor. In one aspect, the attachment state of the vibration sensor is confirmed based on the measurement value of the vibration sensor. In one aspect, the vibration sensor measurements are compared to predetermined thresholds to determine malfunction and / or need for maintenance of the rotating machinery. Effect of the Invention

[0013] According to the present invention, a vibration sensor can be visually attached to a rotating machine at an appropriate position and in an appropriate direction by utilizing the installation position data and the installation direction data associated with the installation position data. Therefore, even if a user who attaches the vibration sensor is unfamiliar with rotating machines, accurate vibration data can be obtained. As a result, the user can accurately determine the occurrence of a malfunction of the rotating machine and / or the need for maintenance. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing a vibration monitoring system for a rotating machine according to one embodiment. The vibration monitoring system shown in FIG. 1 includes two rotating machines (pumps) 1, a vibration sensor 7 attached to each rotating machine 1, and a monitoring device 5 that monitors the measured values ​​of the vibration sensors 7. Although the rotating machine 1 in the vibration monitoring system shown in FIG. 1 is a pump, the type of the rotating machine 1 is arbitrary. For example, the rotating machine 1 may be a fan, an electric motor, and a compressor. Furthermore, the vibration monitoring system may have one rotating machine 1, or may have three or more rotating machines 1. That is, the vibration monitoring system has at least one rotating machine 1.

[0016] 1 is a mobile terminal device such as a smartphone, a tablet computer, or a notebook computer, but the monitoring device 5 may also be an intelligent terminal device that is not suitable for portability, such as a desktop computer. In this case, the monitoring device 5 may be provided in a monitoring room of a factory where the rotating machine 1 is installed.

[0017] 1, the vibration monitoring system may have a cloud system 8 capable of transmitting and receiving data to and from the monitoring device 5. The cloud system 8 may be established within a factory in which the rotating machine 1 is installed, or may be established outside the factory in which the rotating machine 1 is installed.

[0018] Furthermore, the vibration monitoring system includes at least one vibration sensor 7 installed in each rotating machine 1. The vibration sensor 7 is a machine that measures vibrations generated during operation of the rotating machine 1, and a user of the rotating machine 1 determines a malfunction (e.g., breakdown) of the rotating machine 1 and / or the need for maintenance based on the measured values ​​of the vibration sensor 7. In this embodiment, each vibration sensor 7 can be connected to the monitoring device 5 via wire and / or wirelessly, and is configured to be able to transmit and receive data including measured values ​​of vibrations generated in the rotating machine 1 to and from the monitoring device 5. For example, each vibration sensor 7 includes a memory (not shown) that can store measured values, and a communication device (not shown) for transmitting and receiving data to and from the monitoring device 5.

[0019] Although not shown, data transmission and reception between the vibration sensor 7 and the monitoring device 5 may be performed via a repeater. Furthermore, the vibration sensor 7 may be configured to be able to transmit and receive data to and from a cloud system 8. In this case, transmission and reception of data between the vibration sensor 7 and the monitoring device 5 is performed via the cloud system 8.

[0020] Fig. 2 is a schematic diagram showing an example of a monitoring device 5. The monitoring device 5 shown in Fig. 2 is a smartphone, and includes a display 10, a processing device 11 capable of processing information (and / or data) displayed on the display 10, and a communication device (not shown) for transmitting and receiving data to and from external devices such as a vibration sensor 7 and a cloud system 8. The display 10 is configured as, for example, a touch panel. The processing device 11 is, for example, an arithmetic processing device such as a CPU or GPU. Such an arithmetic processing device can process various image data and measurement values ​​of the vibration sensor 7, which will be described later, at high speed.

[0021] In this embodiment, the processing device 11 displays sensor installation information for installing the vibration sensor 7 at an appropriate installation position in an appropriate installation direction on the display 10. The sensor installation information includes type image data representing, as an image, the type of the rotating machine 1, model image data representing, as an image, the model of the rotating machine 1 associated with the type of the rotating machine 1, installation position data representing, as an image, a recommended installation position of the vibration sensor 7 associated with the model of the rotating machine 1, and installation direction data representing, as an image, the appropriate installation direction of the vibration sensor 7 associated with the recommended installation position.

[0022] In this embodiment, the sensor installation information is pre-stored in a memory (not shown) of the vibration sensor 7, and the sensor installation information is transmitted from the vibration sensor 7 to the monitoring device 5 when a user of the rotating machine 1 operates the monitoring device 5. In one embodiment, the sensor installation information may be pre-stored in the monitoring device 5, or may be pre-stored in the cloud system 8. When the sensor installation information is stored in the cloud system 8, the sensor installation information is transmitted from the cloud system 8 to the monitoring device 5 when a user of the rotating machine 1 operates the monitoring device 5.

[0023] When a user installs the vibration sensor 7 on the rotating machine 1, the user operates the monitoring device 5 to display the sensor installation information on the display 10, and installs the vibration sensor 7 based on the sensor installation information. This operation allows the user to install the vibration sensor 7 in an appropriate installation position and in an appropriate installation direction, even if the user is unfamiliar with installing vibration sensors 7. As a result, the user can obtain appropriate measurement values ​​of the vibration sensor 7, and can accurately determine malfunctions and / or the need for maintenance of the rotating machine 1.

[0024] 3 is a schematic diagram showing an example of type image data displayed on the display 10. The type image data shown in FIG. 3 is configured so that the type of rotating machine 1 can be selected from "pump," "fan," and "other." More specifically, the type image data shown in FIG. 3 has buttons corresponding to "pump," "fan," and "other." The user selects the type of rotating machine 1 by pressing (or touching) the button corresponding to the rotating machine 1 on which the vibration sensor 7 is to be installed from the type image data shown in FIG. 3.

[0025] When the user selects the type of rotating machine 1, the processing device 11 causes the display device 10 to display model image data that represents, in an image, the model of the rotating machine 1 associated with the type of rotating machine 1. Figures 4 and 5 are schematic diagrams showing an example of model image data displayed on the display device 10. Figures 4 and 5 show an example of model image data when "pump" is selected from the type image data shown in Figure 3.

[0026] The model image data shown in FIG. 4 is image data corresponding to a horizontal shaft pump, and the model image data shown in FIG. 5 is image data corresponding to a vertical shaft pump. The user can switch between the model image data shown in FIG. 4 and FIG. 5 by operating the monitoring device 5 (for example, swiping the surface of the display 10). The user can visually select the model of the rotating machine 1 in which the vibration sensor 7 should be installed while comparing the rotating machine 1 with the model image data displayed on the display 10. This prevents the user from making a mistake in selecting the model of the rotating machine 1 in which the vibration sensor 7 should be installed. The user can select the model of the rotating machine 1 by pressing (or touching) a button labeled "Next" with the model of the rotating machine 1 in which the vibration sensor 7 should be installed displayed on the display 10.

[0027] In one embodiment, the model image data may include a button that displays the series number or model number of the rotating machine 1 on which the vibration sensor 7 is to be installed. When selecting the model of the rotating machine 1, the user can select from the buttons of the model image data displayed on the display 10 the series number or model number that matches the series number or model number written on a tag attached to the rotating machine 1.

[0028] When the user selects the model of the rotating machine 1, the processing device 11 displays on the display 10 installation position data showing, in an image, the recommended installation positions of the vibration sensor 7 associated with the model of the rotating machine 1. FIG. 6 is a schematic diagram showing an example of the installation position data displayed on the display 10. The installation position data is, for example, data that displays the installation positions of the vibration sensor 7 recommended by the manufacturer of the rotating machine 1 on the external image of the rotating machine 1. FIG. 6 shows the installation position data when the model image data corresponding to the horizontal shaft pump shown in FIG. 4 is selected. In FIG. 6, eight recommended installation positions are shown, but the user may install the vibration sensor 7 in all of the recommended installation positions, or may select some installation positions from the eight recommended installation positions shown to install the vibration sensor 7.

[0029] The installation position data shown in FIG. 6 includes selection buttons 15 for selecting the sensor number assigned to each recommended installation position. The user operates the selection buttons 15 to select the sensor number (i.e., the installation position) of the vibration sensor 7 to be installed, and in this state presses (or touches) the button labeled "Next." When the user presses the button labeled "Next," process The device 11 displays on the display 10 installation direction data that shows, in the form of an image, an appropriate installation direction of the vibration sensor 7 associated with the selected recommended installation position.

[0030] 7 is a schematic diagram showing an example of installation direction data displayed on the display 10. The user can visually recognize the appropriate installation direction displayed on the display 10, which corresponds to the installation position of the selected vibration sensor 7. Therefore, the user can attach the vibration sensor 7 to the rotating machine 1 without making a mistake in the installation direction.

[0031] When multiple vibration sensors 7 are to be installed on the rotating machine 1, the user presses the cancel button shown in Fig. 7 to cause the installation position data shown in Fig. 6 to be displayed on the display 10. Next, the user operates the selection button 15 to select the sensor number (i.e., the installation position) of the next vibration sensor 7 to be installed, and causes the display 10 to display the appropriate installation direction for the next vibration sensor 7. By the user performing these operations for all of the vibration sensors 7 to be installed, it is possible to install all of the vibration sensors 7 in appropriate installation positions and in appropriate installation directions.

[0032] Thus, according to this embodiment, the user can attach the vibration sensor 7 to the rotating machine 1 while visually confirming the appropriate installation position and installation direction of the vibration sensor 7. Therefore, even if the user is unfamiliar with the rotating machine 1, the vibration sensor 7 can be attached to the rotating machine 1 in an appropriate installation position and installation direction. As a result, accurate vibration data can be acquired from the vibration sensor 7, allowing the user to accurately determine the occurrence of a malfunction of the rotating machine and / or the need for maintenance.

[0033] The measurement value of the vibration sensor 7 is stored in any one of the vibration sensor 7, the monitoring device 5, and the cloud system 8 in association with the installation position and installation direction of the vibration sensor 7. In one embodiment, the measurement value of the vibration sensor 7 may be stored in any two or all of the vibration sensor 7, the monitoring device 5, and the cloud system 8 in association with the installation position and installation direction of the vibration sensor 7. When the measurement value of the vibration sensor 7 is stored in multiple devices, even if one of the devices in which the measurement value of the vibration sensor 7 is stored breaks down, the measurement data of the vibration sensor 7 can be restored from the other devices.

[0034] When a user checks the vibration data of the rotating machine 1 (i.e., the measurement value of the vibration sensor 7), processIt is preferable that the device 11 displays on the display 10 the measurement values ​​of the vibration sensor 7 stored in either the vibration sensor 7, the monitoring device 5, or the cloud system 8, together with the installation position and installation direction of the vibration sensor 7 associated with the measurement values.

[0035] FIG. 8 is a schematic diagram showing an example of vibration data displayed on the display 10. The vibration data shown in FIG. 8 includes an external view of the rotating machine 1 in which the mounting positions of the vibration sensors 7 are specified by the sensor numbers of the vibration sensors 7, and a list showing the measurement values ​​of each vibration sensor 7 identified by the sensor numbers, and the mounting positions and mounting directions of the vibration sensors 7 associated with the measurement values. According to the vibration data shown in FIG. 8, the user can identify the measurement values ​​and measurement locations of each vibration sensor 7 at a glance. Therefore, the user can know at a glance which vibration sensor 7 is malfunctioning and its mounting position.

[0036] When the measurement value of each vibration sensor 7 exceeds a predetermined threshold value, or when the measurement value of the vibration sensor 7 exceeds a predetermined tolerance range, process The apparatus 11 may issue an alarm from the monitoring device 5. A predetermined threshold value and a predetermined tolerance range are set for each vibration sensor 7 and are, for example, stored in advance in the monitoring device 5. A user can easily recognize the occurrence of a malfunction and / or the need for maintenance of the rotating machine 1 by the alarm.

[0037] In one embodiment, the monitoring device 5 may be configured to allow the user to set or change the threshold value or tolerance of each vibration sensor 7. FIG. 9 is a schematic diagram of a screen displayed on the display 10 when setting or changing the threshold value or tolerance of each vibration sensor 7. The screen shown in FIG. 9 includes an input window 17 for inputting the threshold value to be set or changed, a selection button 18 for selecting a sensor number assigned to the vibration sensor 7 for which the threshold value is to be set or changed, and a numeric keypad 19 for inputting the set value or changed value of the threshold value in the input window 17. Furthermore, as shown in FIG. 9, it is preferable that the screen also displays an external view of the rotating machine 1 in which the mounting positions of the vibration sensors 7 are clearly indicated by the sensor numbers of the vibration sensors 7. Since the user can visually recognize the position of the vibration sensor 7 for which the threshold value is to be changed, it is possible to prevent the user from making a mistake in selecting the vibration sensor 7 for which the setting value is to be set or changed.

[0038] When a long period of time has passed since the vibration sensor 7 was installed on the rotating machine 1, the installation direction of the vibration sensor 7 may deviate from the initial installation direction (i.e., the appropriate installation direction) due to vibrations occurring in the rotating machine 1 or due to an inspector touching the vibration sensor 7. Therefore, it is preferable that the monitoring device 5 has a function of determining whether or not the installation direction of the vibration sensor 7 is normal. Below, a method of determining whether or not the installation direction of the vibration sensor 7 is normal will be described with reference to Figs. 10 and 11.

[0039] FIG. 10 is a flow chart showing an example of a method for determining whether the installation direction of the vibration sensor 7 is normal or not. FIG. 11(a) is a schematic diagram showing a state in which the vibration sensor 7 capable of measuring vibrations in three axial directions, axial direction X, vertical direction Y, and horizontal direction Z, relative to the rotation axis is normally installed, and FIG. 11(b) is a schematic diagram showing a state in which the vibration sensor 7 is deviated from the normal installation state shown in FIG. 11(a). The vibration sensor 7 shown in FIG. 11(a) is installed on a rotating machine 1 whose rotation axis extends horizontally. Therefore, the axial direction X is in the same plane (horizontal plane) as the horizontal direction Z, and the vertical Y axis extends perpendicular to this horizontal plane. The vibration sensor 7 shown in FIG. 11(a) and FIG. 11(b) is a vibration sensor capable of detecting gravitational acceleration.

[0040] As shown in FIG. 10, first, the rotating machine 1 is stopped (step 1). Next, the monitoring device 5 is operated to obtain three-axis measurement values ​​of the vibration sensor 7. The vibration sensor 7 shown in FIG. 11(a) and FIG. 11(b) is a vibration sensor capable of detecting gravitational acceleration. Next, the monitoring device 5 process The device 11 compares the measured values ​​in the three axial directions with set values ​​for judgment (step 2).

[0041] As described above, the X-axis and Z-axis directions of the vibration sensor 7 lie within a horizontal plane, and the Y-axis direction extends perpendicular to the horizontal plane. Therefore, in the example described with reference to Figures 11(a) and 11(b), the set values ​​for determining the X-axis and Z-axis directions are 0, and the set value for determining the Y-axis direction is 1. When the vibration sensor 7 is properly installed, the measured values ​​in the X-axis and Z-axis directions are approximately 0, and the measured value in the Y-axis direction is approximately 1, as shown in Figure 11(a).

[0042] On the other hand, as shown in Fig. 11(b), when the vibration sensor 7 is deviated from the normal installation direction, at least one of the three-axis measurement values ​​deviates from the set value for judgment. In the example shown in Fig. 11(b), the measurement values ​​in the X-axis and Y-axis directions deviate from the set value for judgment. process The device 11 prestores a tolerance for the difference between the measurement value in each axial direction and the set value for judgment. process If the difference between the measured values ​​in each axial direction and the set value for judgment exceeds the allowable value (see Yes in step 3), the device 11 issues an alarm to inform the user that the installation direction of the vibration sensor 7 is misaligned (see step 4). process If the difference between the measured value in each axial direction and the set value for judgment is within the allowable range, the device 11 ends the installation direction confirmation operation without issuing an alarm (see No in step 3).

[0043] The above-described embodiments have been described for the purpose of enabling a person having ordinary skill in the art to practice the present invention. Various modifications of the above-described embodiments are naturally possible for a person skilled in the art, and the technical idea of ​​the present invention can be applied to other embodiments. Therefore, the present invention is not limited to the described embodiments, but is to be interpreted in the broadest scope according to the technical idea defined by the claims.
