[0026] This application provides a method, equipment, and medium for testing mechanical seals used in pumps.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0028] Pumps are commonly used equipment in the petrochemical industry for transporting high-temperature, high-pressure, and highly corrosive liquids. They generally employ mechanical seals, which prevent high-pressure liquid from leaking out of the pump body along the shaft and allow outside air to leak into the pump body along the shaft.

[0029] In existing technologies, dry gas seals are commonly used as mechanical seals in chemical plant pump areas. Dry gas seals for pumps are a new type of high-performance, long-life seal.

[0030] In practical use, to prevent dry gas leakage, a pressure gauge is usually installed at the mechanical seal, and the data from this gauge is collected and analyzed through on-site inspections by personnel to monitor dry gas leakage in the pump area. However, manually inspecting the mechanical seal in the pump area is costly and inefficient, and it is difficult to obtain timely information on mechanical seal leakage when unexpected situations occur at the mechanical seal site.

[0031] To address the aforementioned issues, this application provides a method, equipment, and medium for testing mechanical seals used in pumps. By collecting and uploading data from the pump area seals via the Internet of Things (IoT), the high cost of manual inspections can be resolved. Simultaneously, real-time acquisition of data from pressure transmitters and other data acquisition devices at the pump area seals allows for timely fault information retrieval in case of seal emergencies, facilitating prompt handling of mechanical seal leakage. Furthermore, this application compares the acquired seal data to be tested with reference data across different dimensions, enabling multi-faceted analysis of the pump area seal condition and ensuring the accuracy of the seal data analysis.

[0032] The technical solutions proposed in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a flowchart illustrating a method for testing mechanical seals for pumps, provided as an embodiment of this application. Figure 1 As shown, the testing method for mechanical seals used in pumps includes the following steps:

[0034] S101. Obtain the sealing data to be tested uploaded by the data acquisition device installed at the pump area seal; wherein, the sealing data to be tested includes at least one of the following: pressure value, vibration value, displacement value, and equipment number of the pump to be tested.

[0035] In one embodiment of this application, the data acquisition device communicates with a pre-configured RTU coordinator via Zigbee. The pre-configured RTU coordinator performs RS485 communication protocol conversion and uploads the seal data to be tested to the IoT management platform via wireless transmission to obtain the seal data to be tested. The IoT management platform includes an organic seal leakage detection application.

[0036] Specifically, taking the acquisition of pressure values ​​as an example, in this embodiment of the application, pressure values ​​of different pump areas are acquired by a pressure transmitter installed in the pump area. Figure 2 A flowchart illustrating a method for testing mechanical seals for pumps, as provided in this application embodiment, is shown below. Figure 2As shown, different pressure transmitters are installed in different pump areas. After the terminal equipment acquires the pressure value, it communicates via Zigbee to the RTU coordinator, where it is converted to RS485 communication protocol. The data is then collected and sent to the IoT management platform via a 5G CPE. The IoT management platform deploys a mechanical seal leakage detection application, which can view and analyze the collected data in real time and issue alarms for abnormal data. Alarm information is pushed to individuals or DingTalk groups in real time, facilitating timely on-site handling by maintenance personnel.

[0037] Figure 3 A schematic diagram of a data acquisition network provided in an embodiment of this application, such as... Figure 3 As shown, multiple wireless pressure transmitters are installed in different pumping areas. Since the existing pressure gauges in the pumping areas cannot meet the data transmission requirements, the on-site pressure gauges need to be replaced with remote pressure gauges, and wireless pressure transmitters are the preferred choice for the field. Multiple wireless pressure transmitters collect sealing data from their respective mechanical seal devices. After being networked on-site, the wireless pressure transmitters collect the data via a 4G / 5G wireless network to the AiIoT smart IoT platform for analysis.

[0038] S102. Based on the device number in the seal data to be tested, determine the reference seal data corresponding to the pump with the same device code specification in the preset seal database.

[0039] In one embodiment of this application, the specification information of the pump to be tested is determined based on the device code. Based on the specification information, a corresponding reference device is determined; wherein the specification information corresponding to the reference device is the same as the specification information corresponding to the pump to be tested. Reference sealing data corresponding to the reference device is determined from a preset reference sealing database; wherein the preset reference sealing database includes multiple reference devices and reference sealing data corresponding to each of the multiple reference devices.

[0040] Specifically, different pumps are assigned corresponding equipment codes, which uniquely identify the equipment. By identifying the equipment code, the corresponding specification information can be obtained, allowing the identification of multiple pumps with the same specification. This application embodiment includes a preset reference seal database containing information on multiple pumps of different specifications, as well as reference seal data corresponding to each specification. This reference seal data represents the sealing data under normal operating conditions for different equipment.

[0041] S103. Based on the transmission time corresponding to the sealing data to be tested and the category of the sealing data to be tested, the sealing data to be tested is compared with the reference sealing data in different dimensions.

[0042] In one embodiment of this application, the sealing data to be tested is divided into multiple groups of data based on data category. Each group of data is compared with a preset sealing data threshold in the reference sealing data to obtain a first sealing detection result. The sealing data to be tested corresponding to the current pump area at the previous moment is determined. Based on the type of the sealing data to be tested, the obtained current sealing data to be tested is classified and associated with the sealing data to be tested at the previous moment. The associated sealing data is compared with a preset continuous sealing change value in the reference sealing data to obtain a second sealing detection result. Based on the first and second sealing detection results, the sealing detection information corresponding to the pump to be tested is determined.

[0043] Specifically, based on the data category, the data to be detected is divided into multiple groups. For example, based on the category of the device that collects the data, the data to be detected can be divided into pressure value data group, vibration value data group, and displacement value data group.

[0044] Furthermore, the acquired data of different categories are compared with corresponding preset sealing data thresholds to obtain the first sealing detection result. For example, the pressure value is compared with a preset pressure threshold. If the currently acquired pressure value does not meet the conditions of the preset pressure threshold, the pressure value is determined to be an abnormal value, and the mechanical seal device corresponding to the pressure value has a leakage problem. Similarly, the vibration value is compared with a preset vibration threshold. If the currently acquired vibration value does not meet the conditions of the preset vibration threshold, the vibration value is determined to be an abnormal value, and the mechanical seal device corresponding to the vibration value has a leakage problem.

[0045] Furthermore, after acquiring the seal data to be tested at the current moment, on the one hand, the seal data to be tested at the current moment is compared with a preset threshold to determine whether the data value of the seal data to be tested at the current moment meets the requirements. On the other hand, the seal data to be tested at the current moment is correlated with the seal data to be tested at the previous moment to analyze the changes in data over a continuous period of time, so as to determine the stable operation of the mechanical seal device to be tested over a period of time.

[0046] Specifically, the data category corresponding to the seal data to be tested at the current moment is determined. Based on this data category, the seal data to be tested corresponding to the same category at the previous moment is determined. For example, if the current category is pressure value, then the pressure value of the mechanical seal device corresponding to that pressure value at the previous moment is determined. The seal data to be tested at consecutive moments corresponding to the same mechanical seal device are correlated, so that the leakage situation of the mechanical seal device can be analyzed over consecutive moments through the correlated data.

[0047] Specifically, the associated data of different categories are compared with the preset continuous sealing change value to determine whether the seal has leaked, so as to obtain the second sealing detection result.

[0048] Furthermore, by analyzing the results of the first and second seal tests, the seal leakage problem can be analyzed from different dimensions to ensure the accuracy of the seal test.

[0049] In one embodiment of this application, a pressure change graph is plotted based on pressure values ​​associated within consecutive time intervals, a vibration change graph is plotted based on vibration values ​​associated within consecutive time intervals, and a displacement change graph is plotted based on displacement values ​​associated within consecutive time intervals. The pressure change graph is compared with a preset continuous pressure change graph in the reference seal data, the vibration change graph is compared with a preset continuous vibration change graph in the reference seal data, and the displacement change graph is compared with a preset continuous displacement change graph in the reference seal data. Based on the comparison results, a second seal detection result is obtained.

[0050] Specifically, based on the acquired data values ​​of different categories over a continuous time period, pressure variation diagrams, vibration variation diagrams, and displacement variation diagrams can be plotted. The pressure variation diagram is compared with a preset continuous pressure variation diagram, which represents pressure variation under normal, leak-free conditions. The vibration variation diagram is also compared with a preset continuous vibration variation diagram, which represents vibration variation under normal, leak-free conditions. Finally, the displacement variation diagram is compared with a preset continuous displacement variation diagram, which represents displacement variation under normal, leak-free conditions.

[0051] By comparing the data graphs with those under normal, leak-free conditions, it can be determined whether any abnormalities have occurred in the data detected over a continuous period of time, thereby detecting sealing leakage problems.

[0052] S104. Based on the comparison results, determine the sealing detection information corresponding to the pump to be tested, and perform alarm maintenance on the pump to be tested based on the sealing detection information.

[0053] In one embodiment of this application, if the first seal detection result does not meet the preset seal data threshold condition, and the second seal detection result does not meet the preset continuous seal change value threshold condition, the sealing condition of the pump under test is determined to be a severe seal failure state. If the first seal detection result does not meet the preset seal data threshold condition, or the second seal detection result does not meet the preset continuous seal change value threshold condition, the sealing condition of the pump under test is determined to be a normal seal failure state. If the first seal detection result meets the preset seal data threshold condition, and the second seal detection result meets the preset continuous seal change value threshold condition, the sealing condition of the pump under test is determined to be a normal seal state.

[0054] Specifically, by analyzing the results of the first and second seal tests, the detection can be performed from two dimensions: whether a leakage problem occurs at a single moment and whether the operation is stable over a continuous period of time, thereby ensuring the accuracy of leakage detection.

[0055] Furthermore, the results of the first and second seal tests are analyzed comprehensively. If both the first and second seal tests fail to meet the requirements, it is determined that the pump under test has a leakage problem, and this leakage problem is relatively serious. If either the first or second seal test result fails to meet the requirements, it is determined that the pump under test has a leakage problem, and this leakage problem is relatively minor. If both the first and second seal test results meet the requirements, it is determined that the pump under test does not have a leakage problem.

[0056] In one embodiment of this application, when the sealing detection information meets the alarm conditions, the alarm information is sent to the alarm software of the preset terminal through a preset data interface. The alarm software compares the received alarm information with preset alarm severity level thresholds, and alarms are triggered in different ways based on the comparison results.

[0057] Specifically, this application embodiment includes a DingTalk data interface to push alarm information from the Aiot platform database to DingTalk. A DingTalk alarm group is set up, and alarm robots are added within the group. If the alarm information is a multi-level alarm, alarm robots at each level can be added, and alarm push information can be configured. When the on-site pressure exceeds the alarm threshold, a push notification is promptly sent to the group. Figure 4 This is a schematic diagram of an alarm information push provided in an embodiment of this application, such as... Figure 4 As shown, the alarm robot can publish the current value of the sealing data to be tested, as well as the time when the data was received, within the group to remind relevant testing personnel to repair equipment with leakage problems.

[0058] In one embodiment of this application, a screen configuration corresponding to the data acquisition device is determined. The data to be detected uploaded by the data acquisition device is input into the screen configuration to display the real-time operating status of the data acquisition device. Alarm conditions for the data acquisition device corresponding to the screen configuration are determined. If the real-time displayed operating status of the data acquisition device meets the alarm conditions, a pop-up alarm is triggered, and the alarm information is recorded.

[0059] Specifically, this application deploys a mechanical seal leakage detection application in an AIoT platform, performs visual editing, configures each data acquisition device with pseudonyms, and inputs the received data into the corresponding screen configuration for real-time display. For example, each pressure transmitter is configured with a screen, and field data is referenced and displayed in real time. Alarm thresholds are set for each pressure transmitter, and a pop-up alarm is displayed and recorded when an alarm occurs, supporting historical data query.

[0060] This application's embodiments utilize IoT technology to replace manual labor and solve the problems of inspection and maintenance. Through the application of pressure transmitters and edge computing gateways, automatic pressure detection is achieved, and potential leaks are reported in real time. Simultaneously, based on equipment location, automatic guidance for maintenance and repair is provided, making it highly efficient and convenient. Furthermore, by using pressure transmitters, while addressing mechanical seal leakage issues, the acquisition of pressure values ​​also effectively reflects changes in mechanical seal pressure. Combined with intelligent analysis of massive amounts of data, this better supports production activities.
