Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a method for real-time monitoring the sealing performance of a valve body of a plunger pump. Background Art

[0002] At present, plunger pumps are used in many industrial fields, such as oil extraction and chemical transportation. The valve body is a key component of the plunger pump. If the valve body is not sealed well, it will lead to leakage, resulting in unstable flow, pressure fluctuations and energy waste. Therefore, it is particularly important to monitor the sealing of the plunger pump valve body in real time.

[0003] However, the traditional detection method often requires regular shutdown for disassembly inspection, which is not only time-consuming and labor-intensive, but also cannot timely detect changes in the sealing performance of the valve body during operation. At the same time, during the inspection, most of the inspections are based on manual experience, which cannot accurately guarantee the sealing performance, thus greatly reducing the monitoring effect of the sealing performance of the plunger pump valve body.

[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a method for real-time monitoring of the sealing performance of a plunger pump valve body. Summary of the Invention

The monitored pressure data and import and export flow data are analyzed through a pressure-flow relationship model in a main control center, thereby determining the sealing of the valve body of the plunger pump, thereby facilitating the detection of whether there is a leak in the sealing of the valve body of the plunger pump. Finally, when it is determined that there is a leak, the monitoring sensor is self-calibrated to eliminate the false alarm operation of the monitoring sensor itself, and an active alarm operation is performed after the self-calibration test is passed, thereby ensuring the comprehensiveness, accuracy and reliability of the real-time monitoring of the sealing of the valve body of the plunger pump, and at the same time, ensuring the operation effect of the plunger pump.

[0066] In this embodiment, the cavity structure refers to the three-dimensional structure of the internal cavity of the plunger pump, and the purpose is to determine the deployment position of the sensor based on the cavity structure.

[0067] In this embodiment, the monitoring sensor includes a pressure sensor and a flow sensor.

[0068] In this embodiment, the service function refers to the service type that the monitoring sensor can perform and the type of data that can be monitored.

[0069] In this embodiment, the pressure-flow relationship model is a function that can characterize the pressure-flow relationship and is obtained by analyzing the pressure data and the inlet and outlet flow data in the plunger pump.

[0070] In this embodiment, the self-calibration test refers to testing the performance of the monitoring sensor itself, with the purpose of proactively eliminating false alarms of the monitoring sensor or false alarms caused by its own functional defects when a leak is determined to exist.

[0071] In this embodiment, the active alarm operation refers to activating an alarm device preset on the plunger pump and simultaneously sending a remote early warning notification to the remote communication terminal.

[0072] The beneficial effects of the above technical solution are: by effectively determining the deployment position of each monitoring sensor according to the cavity structure of the plunger pump and the business function of the monitoring sensor, comprehensive and effective monitoring of the valve sealing of the plunger pump is ensured, and the monitored pressure data and import and export flow data are analyzed through the pressure-flow relationship model in the main control center, thereby realizing the determination of the valve sealing of the plunger pump, thereby facilitating the discovery of whether there is a leak in the valve sealing of the plunger pump. Finally, when it is determined that there is a leak, the monitoring sensor is self-calibrated to eliminate the false alarm operation of the monitoring sensor itself, and an active alarm operation is performed after the self-calibration test is passed, thereby ensuring the comprehensiveness, accuracy and reliability of the real-time monitoring of the valve sealing of the plunger pump, and at the same time, ensuring the operation effect of the plunger pump.

[0073] Example 2:

[0074] Based on Example 1, this embodiment provides a method for real-time monitoring of the sealing performance of a plunger pump valve body. In step 1, the deployment location of each monitoring sensor is determined based on the cavity structure of the plunger pump and the service function of the monitoring sensor, including:

[0078] The working business of different cavity areas is matched with the business attributes of the monitoring sensors, the deployment positions of different monitoring sensors in the cavity structure of the plunger pump are determined, and a sensor deployment guidance map is generated based on the deployment positions for deployment feedback.

[0079] In this embodiment, the working business refers to the specific function or task undertaken by the cavity area during the operation of the plunger pump. For example, the cavity area is mainly responsible for sucking in fluid (suction cavity), and its working business is to provide space during the oil suction process of the plunger pump so that the oil can smoothly enter the pump.

[0080] In this embodiment, the configuration parameters refer to relevant parameters used to define the operation of the sensor and the performance it has.

[0081] In this embodiment, matching the working services of different cavity areas with the service attributes of the monitoring sensors is to obtain a sensor that can monitor the working services of the cavity area after matching the working services with the service attributes of the monitoring sensors, thereby effectively ensuring the accuracy of monitoring.

[0082] In this embodiment, the sensor deployment guide map is a guide map that is drawn by marking the deployment positions of different monitoring sensors in the cavity structure of the plunger pump and can accurately locate each monitoring sensor.

[0083] The beneficial effects of the above technical solution are: by globally scanning and analyzing the cavity structure of the plunger pump, the working operations of different cavity areas in the plunger pump can be determined. At the same time, combined with the configuration parameters of the monitoring sensor, the deployment position of each monitoring sensor in the cavity structure of the plunger pump can be effectively determined, which provides convenience and guarantee for the comprehensive collection of pressure data and import and export flow data.

[0089] In this embodiment, the monitoring requirement is based on the input from the management terminal and is used to determine the data collection frequency and data collection accuracy of the monitoring sensor.

[0090] In this embodiment, the monitoring object is the type of monitored data, namely, pressure data and inlet and outlet flow data. The subject differentiation refers to differentiating the types of collected data, namely, differentiating pressure data from inlet and outlet flow data.

[0091] The beneficial effect of the above technical solution is: by adapting the business parameters of each monitoring sensor according to the monitoring requirements, and collecting the pressure data and inlet and outlet flow data in the plunger pump after the business parameter adaptation is completed, reliable data guarantee is provided for real-time monitoring of the sealing of the plunger pump valve body.

[0094] Obtain the subject differentiation results of the pressure data and the import and export flow data at each moment, and add time labels to the pressure data, import flow data, and export flow data at each moment based on the subject differentiation results. At the same time, add data category labels to the pressure data, import flow data, and export flow data;

[0095] Divide different moments into independent storage areas based on time labels, and divide each independent storage area into data category spaces based on data category labels;

[0096] Based on the results of independent storage area and data category space division, the pressure data, inlet flow data and outlet flow data at each moment are cached independently.

[0097] In this embodiment, the time tags are determined based on different time periods and are used to distinguish the data results of the pressure data, the inlet flow data, and the outlet flow data at different time periods.

[0098] In this embodiment, the data category label is a characterization identifier used to distinguish different data types.

[0099] The beneficial effects of the above technical solution are: by distinguishing the collected pressure data and inlet and outlet flow data at different times and different data categories, it is convenient to effectively execute the subsequent real-time monitoring of the sealing of the plunger pump valve body; secondly, the differentiated pressure data and inlet and outlet flow are effectively cached to ensure the reliability of the final data, and it is also convenient to perform the corresponding real-time monitoring operation of the sealing.

[0100] Example 5:

[0101] Based on Example 1, this embodiment provides a method for real-time monitoring of the sealing performance of a plunger pump valve body. After deployment is completed, the pressure data and inlet and outlet flow data in the plunger pump are collected in real time, including:

[0105] In this embodiment, queue sorting refers to sorting the collected pressure data and inlet and outlet flow data in the order of collection time.

[0106] In this embodiment, global data scanning refers to determining the amount of data of each node after the queue is sorted.

[0108] Example 6:

[0109] Based on Example 1, this embodiment provides a real-time monitoring method for the sealing performance of a plunger pump valve body. In step 2, a comprehensive analysis is performed on the pressure data and the inlet and outlet flow data based on the pressure-flow relationship model in the main control center, and the sealing performance of the plunger pump valve body is determined based on the comprehensive analysis results, including:

[0110] Access the plunger pump working database based on the main control center, and retrieve the benchmark pressure data and benchmark inlet and outlet flow data of the plunger pump under the standard working state based on the access result;

[0111] The benchmark pressure data and benchmark inlet and outlet flow data are divided into value intervals to obtain multi-level training sample data of the plunger pump, wherein the number of training sample data corresponding to each value interval is not unique;

[0112] Determine the values ​​of the training sample data at each level, and use the determined values ​​to construct a data control group;

[0113] Perform trend analysis on the values ​​of different training sample data in the data control group, and obtain the relationship function between the benchmark pressure data and the benchmark import and export flow data in each value interval based on the trend analysis results;

[0114] Determine the adaptive parameter correction amount of the relationship function under different value intervals, and perform integrated training on the relationship functions of different value intervals based on the adaptive parameter correction amount to construct a pressure-flow relationship model;

[0115] Based on the pressure-flow relationship model, a comprehensive analysis is performed on the real-time collected pressure data and import and export flow data, and based on the comprehensive analysis results, the theoretical export flow data under the current pressure data and current import flow data is obtained;

[0116] Comparing the theoretical outlet flow data with the outlet flow data collected in real time, and determining the difference interval between the theoretical outlet flow data and the outlet flow data collected in real time based on the difference comparison result;

[0117] When the difference interval is greater than a preset threshold, it is determined that there is leakage in the sealing of the plunger pump valve.

[0118] In this embodiment, the plunger pump operation database is set in advance and is used to store the corresponding operation data of the plunger pump under normal working conditions.

[0119] In this embodiment, the value interval division refers to distinguishing the reference pressure data and the reference inlet and outlet flow data according to the magnitude of their values, and the distinction is made according to a preset standard.

[0120] In this embodiment, the multi-level training sample data refers to the result obtained by dividing the reference pressure data and the reference inlet and outlet flow data into value intervals.

[0121] In this embodiment, constructing a data control group using the determined values ​​means constructing the data using the training sample data obtained after the division as a data reference standard.

[0122] In this embodiment, the relationship function is used to characterize the correlation between the internal pressure data and the inlet and outlet flow data when the plunger pump is operating normally.

[0123] In this embodiment, the adaptive parameter correction amount refers to the parameter that needs to be adjusted in the relationship function under the corresponding value range when the pressure data and the import and export flow data change. The purpose is to determine the real-time correspondence between the pressure data and the import and export flow data under different value ranges, thereby enriching the application scenarios.

[0124] In this embodiment, the theoretical outlet flow data refers to the theoretical outlet flow data obtained by analyzing the current pressure data and the current inlet flow data through the obtained pressure-flow relationship model, which provides a basis for determining whether the plunger pump has leakage.

[0125] In this embodiment, the preset threshold value is set in advance and is a reference for measuring the presence of leakage in the valve body sealing of the plunger pump, and can be adjusted.

[0126] The beneficial effects of the above technical solution are: by scheduling the benchmark pressure data and benchmark inlet and outlet flow data of the plunger pump under the standard working state, and analyzing the retrieved benchmark pressure data and benchmark inlet and outlet flow data, the pressure-flow relationship model can be accurately and effectively constructed. Secondly, the collected pressure data and inlet and outlet flow data are comprehensively analyzed through the constructed pressure-flow relationship model, and the theoretical outlet flow data obtained by the comprehensive analysis is compared with the collected outlet flow data to achieve accurate and effective judgment on whether there is a leak in the valve body sealing of the plunger pump, thereby ensuring the accuracy and reliability of the monitoring of the valve body sealing of the plunger pump.

[0127] Example 7:

[0128] Based on Example 6, this embodiment provides a method for real-time monitoring of the sealing performance of a plunger pump valve body, which determines whether there is leakage in the sealing performance of the plunger pump valve body, including:

[0129] Obtain leakage determination results of the plunger pump valve body sealing performance, and actively intervene in the working parameters of the plunger pump with multiple different values ​​based on the leakage determination results;

[0130] Based on the active intervention results, the fluctuation range of the difference between the theoretical outlet flow data and the real-time collected outlet flow data under different working parameter values ​​is determined;

[0131] The leakage of the valve body sealing of the plunger pump is quantified based on the fluctuation range of the difference interval, and the leakage level of the valve body sealing of the plunger pump is obtained based on the quantification result.

[0132] In this embodiment, the active intervention of taking multiple different values ​​of the working parameters of the plunger pump based on the leakage judgment result means that when it is determined that the plunger pump has a leak, the working parameters of the plunger pump are adjusted to different values ​​multiple times, in order to verify whether the plunger pump actually has a leak.

[0133] In this embodiment, quantifying the leakage of the valve seal of the plunger pump based on the fluctuation range of the difference interval refers to determining the leakage degree of the valve seal of the plunger pump.

[0134] The beneficial effect of the above technical solution is: by actively intervening in the working parameters of the plunger pump with different values ​​multiple times when it is determined that there is a leak in the valve body sealing of the plunger pump, the leakage level of the valve body sealing of the plunger pump is determined according to the active intervention results, which makes it easier for management personnel to effectively understand the leakage situation of the valve body sealing of the plunger pump, thereby facilitating corresponding emergency response operations.

[0136] Based on Example 1, this embodiment provides a method for real-time monitoring of the sealing performance of a plunger pump valve body, such as Figure 3 As shown, in step 3, when it is determined that there is a leak in the valve body of the plunger pump, a self-calibration test is performed on the monitoring sensor, and an active alarm operation for the leakage of the valve body of the plunger pump is performed after the self-calibration test passes, including:

[0137] Step 301: When it is determined that there is leakage in the valve body of the plunger pump, the monitoring link of the monitoring sensor is switched to a preset external standard source, wherein the external standard source includes a pressure standard source and a flow standard source;

[0138] Step 302: applying multiple sets of different parameter values ​​to the monitoring sensor according to the external standard source based on the switching result, and obtaining the monitoring response value of the monitoring sensor in real time based on the application result;

[0139] Step 303: Perform self-calibration on the monitoring sensor based on the monitoring response value and the applied multiple sets of different parameter values, and when the monitoring response value and the applied multiple sets of different parameter values ​​are the same, it is determined that the piston pump valve body leakage is real.

[0140] In this embodiment, the preset external standard source is set in advance, including a pressure standard source and a flow standard source, which are used to generate standard values ​​of pressure and flow.

[0154] Construct a sealing test record sheet for the plunger pump valve body, and when there is a leak in the plunger pump valve body, record the time and location of each leak in the sealing test record sheet;

[0155] When there is data update in the sealing test record table, the performance of the plunger pump valve body is re-evaluated based on the time and location of the plunger pump valve body leakage, and the effective working state of the plunger pump valve body is obtained based on the re-evaluation result;

[0156] A sealing evaluation report of the plunger pump valve body is generated based on the effective working state and the time and position of the current plunger pump valve body leakage, and the sealing evaluation report is synchronously fed back to the remote communication terminal.

[0157] In this embodiment, the effective working state refers to the real-time status of the plunger pump valve, including whether it can work normally.

[0158] The beneficial effect of the above technical solution is: by constructing a sealing test record sheet, the time and location of each piston pump valve body leakage can be effectively recorded through the sealing test record sheet. At the same time, the performance of the piston pump valve body is re-evaluated according to the recording results, and a corresponding sealing evaluation report is generated, which is convenient for management personnel to effectively understand the situation of the piston pump valve body according to the sealing evaluation report, thereby ensuring the operational reliability of the piston pump.
