[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In large-scale raw water pumping stations, there are many factors that affect the quality and economy of water production. The problem that this invention aims to solve is how to classify the operational data (such as basic data, operational data, and monitoring data) according to the degree of impact on the production and operation of pumping station equipment, summarize and analyze the key data, conduct in-depth research and analysis of the data, quickly find out the reasons for the reduction in equipment operating efficiency, and take timely countermeasures to reduce the economic losses caused by speed loss and downtime.

[0024] This invention relates to the establishment and analysis of the operating efficiency model of pump units in large-scale raw water pumping stations, and is a method for analyzing and improving the operating efficiency of raw water pumping stations.

[0025] This invention can quickly identify time-loss issues in water pump units by accurately calculating various parameters. It provides a scientific and accurate reference standard for water pump station management and maintenance personnel to assess pump unit performance and address the underlying causes of decreased operating efficiency. Traditional methods, while also showing a decrease in the overall equipment efficiency evaluation index when analyzing time loss, do so slowly and fail to reflect the time-loss problem in a timely manner, inevitably leading to greater economic losses. This is what this invention aims to avoid. The specific implementation scheme of this invention is described in detail below.

[0026] Please see Figure 1 This invention provides a method for analyzing the operating efficiency of a water pump unit, the method comprising:

[0027] S110, Obtain relevant parameters of the water pump unit. Further, the relevant parameters of the water pump unit include parameters of related equipment affecting the operating efficiency of the water pump unit; the parameters of the related equipment include equipment type, equipment name, daily planned production time of the equipment, initial commissioning time of the equipment, equipment downtime due to malfunction, and / or unplanned downtime of the equipment.

[0028] In one embodiment of the present invention, the types and names of equipment that have a direct impact on the operating efficiency of the pumping station are statistically analyzed, equipment operating status data are obtained through on-site data collection, and the operating status data of each piece of equipment are uniformly summarized and stored in the database by using heterogeneous database technology, providing a data basis for the calculation and analysis in step S120.

[0029] The application specifies two types of data required for the operational efficiency model: monitoring data and planned data. The data acquisition module collects existing equipment data to obtain various monitoring parameters for the operational efficiency model, such as planned start-up time, unplanned downtime, actual water supply, and planned water supply. This data can be extracted from the company's existing system database. The other part, primarily equipment status time, is directly collected from the equipment monitoring system. Equipment status time includes the actual start-up and downtime of the equipment; actual start-up time is a parameter used to calculate equipment availability.

[0030] In this application, the types and names of equipment that directly affect the operating efficiency of the pumping station (or water pump unit) are statistically analyzed. The operating status data of the equipment is collected and stored in the database through the data acquisition module, providing a data basis for the analysis of the operating efficiency of the water pump unit.

[0031] For example, for three units, based on the daily planned production time, initial commissioning time, downtime due to malfunction, and unplanned downtime of each unit for a month, the availability rate of each unit can be calculated through statistical analysis.

[0032] S120, using an operating efficiency model to calculate and process the relevant parameters, obtain the availability parameter, performance index parameter, and quality index parameter of the water pump unit, and process the availability parameter, performance index parameter, and quality index parameter to obtain the operating efficiency parameter of the water pump unit; the availability parameter is the percentage of the actual start-up time of the water pump unit to the planned start-up time; the performance index parameter is the percentage of the planned cycle time of the water pump unit to the actual cycle time; the quality index parameter is the percentage of the actual water supply to the planned water supply.

[0033] Specifically, the operational efficiency model is: OEE = Availability (EA) × Performance Index (PE) × Quality Index (RQ);

[0034] in, Actual power-on time = Planned power-on time - Unplanned downtime;

[0035] The performance index PE reflects the loss in water supply speed, including any factors that prevent the water supply from operating at its maximum speed; the actual cycle time is equal to the planned cycle time (or theoretical cycle time) minus the sum of time losses due to equipment wear and operational errors, i.e., actual cycle time = planned cycle time - (time losses due to equipment wear + time losses due to operational errors).

[0036] The theoretical water supply cycle (i.e., the planned cycle time) is a constant D0, and the actual water supply cycle (i.e., the actual cycle time) for each unit is D0. i The water supply cycle difference is ΔD i =D i -D0, for n D's i There are n sample observations, namely ΔD1, ΔD2, ..., ΔD n , i=1,…,n; find ΔD1, ΔD2,…, ΔD n The minimum value ΔD (1) and maximum value ΔD (n) , i.e. ΔD (1) =min(ΔD1,ΔD2,…,ΔD) n ), ΔD (n) =max(ΔD1,ΔD2,…,ΔD n Select a value less than ΔD. (1) The number u and the sum of ΔD are greater than ΔD (n) Let u and v be natural numbers; determine the number of groups k based on the sample size, divide the interval (u, v) into k subintervals, and select the division points: u = x0 < x1 < ... < x j-1 <x j <...<x k=v, divide the interval (u,v) into k subintervals: (u,x1], (x1,x2], ..., (x...v) j-1 x j ],...,(x k-1 ,v], the j-th subinterval (x j-1 x j The length of ] is: Δx j =x j -x j-1 , j = 1, 2, ..., k.

[0037] Assume that each subinterval has the same length: Analyze the above n data points (i.e., n sample observations) in each subinterval (x j-1 x j Frequency n within ] j (That is, the number of times it occurs; the frequency is obtained through statistics), and then the relative frequency is calculated. Because when the capacity n is large enough, the frequency of the random variable X in the i-th subinterval is approximately equal to its probability, that is: f i ≈P{x i-1 <X≤D i}, where X represents a random variable, i = 1, 2, ..., k. This is the algorithm for calculating the water supply cycle difference within the theoretical cycle time (planned cycle time) calculation model.

[0038] The quality index RQ is used to evaluate the water supply achievement rate.

[0039] S130, Analyze the operating efficiency parameters of the water pump unit according to the preset standard, and obtain the operating efficiency analysis results of the water pump unit.

[0040] In one embodiment of the present invention, the preset standard can be formulated according to actual needs or it can be an industry standard. For example, a standard for evaluating the operating efficiency of a water pump unit can be formulated. For example, a standard for evaluating the operating efficiency of a water pump unit can be formulated based on the actual operating conditions of the original water pumping station, as shown in Table 1.

[0041] Table 1: Evaluation Criteria for the Operating Efficiency of Water Pump Units

[0042]

[0043] In this application, the operational efficiency analysis results can be presented in various formats, such as reports, generating pump station operational efficiency reports to display the pump station's operational efficiency in detail using tables. The report display function can be implemented in a web-based system using Element-UI technology. The server calculates operational efficiency-related data from the industrial historical database and uses Element-UI's Table component to draw the operational efficiency report. Users can view the pump station unit's operational efficiency data and related reports through a web browser interface, including daily trend charts of operational efficiency, availability, performance index, quality index, and unit status pie charts for the same type of equipment in the pump station.

[0044] In this application, the operating efficiency model is an independent measurement tool used to represent the ratio of actual production capacity to theoretical capacity. However, excessive pursuit of operating efficiency can also lead to problems. For example, in order to pursue high equipment availability, it is not advisable to increase the operating speed of equipment and reduce the number of normal maintenance operations simply to improve equipment operating efficiency.

[0045] Furthermore, the analysis in this application can identify the specific losses incurred during equipment operation and identify areas for improvement. The purpose of statistically analyzing various time losses is to achieve improvements and enhance efficiency. These operational stages include: equipment maintenance, upkeep, and material shortages; the time lost during each stage that affects startup is the time loss for that stage.

[0046] In this application, the low operating efficiency of equipment is generally caused by a variety of reasons, and each reason may have a different impact on operating efficiency. Calculating different "rates" of operating efficiency separately can reflect different types of losses. For example, downtime cause analysis. In the process of calculating the availability rate and performance index of operating efficiency separately, a low availability rate can reflect excessively long unit downtime. Then, using PM analysis, the specific reasons for the long unit downtime can be determined step by step.

[0047] This application uses PM analysis to analyze the reasons for low operating efficiency. For example, when the operating efficiency of equipment is low, the calculated operating efficiency data shows that the equipment availability is low. Therefore, the equipment availability is highlighted with a box, and the reason for the low equipment availability is asked. It is found that the downtime caused by equipment failure is too long. The analysis continues until the root cause is found.

[0048] Based on the above analysis, targeted improvement and enhancement measures can be taken, such as reducing downtime due to malfunctions, reducing downtime caused by equipment wear and tear, and reducing downtime caused by shortages of spare parts, which are very important for improving equipment availability.

[0049] For example, as shown in Table 2, based on the historical records of the daily planned start-up time, downtime due to malfunctions, material shortage time, employee loss time, and other losses for the three generating units, the availability rate of each unit was calculated through statistical analysis. Sorted from lowest to highest, the availability rate of Unit #3 was only 82.01%, meaning it was in a downtime state for approximately 8% of the time. The analysis results show that the low equipment availability was mainly due to material shortages.

[0051]

[0052] In one embodiment of the present invention, based on the operating efficiency loss time record table shown in Table 2, the causes of equipment failure caused by major fault downtime are analyzed. As shown in Table 3, targeted improvements are made based on the fault type, cause analysis, and suggestions.

[0057] S121a, Obtain parameters of relevant equipment that affect the operating efficiency of the water pump unit within a preset time period;

[0058] S122a, extract the parameters of the corresponding equipment from the parameters of the relevant equipment, including equipment type, equipment name, daily planned production time of the equipment, initial commissioning time of the equipment, equipment downtime due to failure and / or unplanned downtime of the equipment.

[0060] S124a, the availability parameters of the water pump unit are obtained based on the availability parameters of the relevant equipment.

[0061] In one embodiment of the present invention, step S120, which involves processing the relevant parameters to obtain the performance index parameters of the water pump unit, includes the following implementation process:

[0062] S121b, Obtain parameters of relevant equipment that affect the operating efficiency of the water pump unit within a preset time period;

[0063] S122b, extract the parameters of the corresponding equipment from the parameters of the relevant equipment, including equipment type, equipment name, daily planned production time of the equipment, initial commissioning time of the equipment, equipment downtime due to failure and / or unplanned downtime of the equipment.

[0065] S124b, obtain the performance index parameters of the water pump unit based on the performance index parameters of the relevant equipment.

[0066] In one embodiment of the present invention, step S120, which involves processing the relevant parameters to obtain the quality index parameters of the water pump unit, includes the following implementation process:

[0067] S121c, Obtain parameters of relevant equipment that affect the operating efficiency of the water pump unit within a preset time period;

[0068] S122c, extract the parameters of the corresponding equipment from the parameters of the relevant equipment, including equipment type, equipment name, daily planned production time of the equipment, initial commissioning time of the equipment, equipment downtime due to failure and / or unplanned downtime of the equipment.

[0070] S124c, obtain the quality index parameters of the water pump unit based on the quality index parameters of the relevant equipment.

[0071] See Figure 2 As shown, in one embodiment of the present invention, the method for analyzing the operating efficiency of the water pump unit further includes:

[0072] S140, Process and display the operating efficiency parameters of the water pump unit, including: displaying daily trend charts of operating efficiency parameters, availability parameters, performance index parameters, quality index parameters, and / or a pie chart of the health status of the water pump unit for each relevant device affecting the operating efficiency of the water pump unit.

[0073] In one embodiment of the present invention, in the web-based expert guidance system, the calculated data of operating efficiency parameters are displayed graphically using Element-UI and Echarts technologies. The content of the graphs may include: availability rate, performance index, quality index of all water pumps, as well as daily trend charts of operating efficiency, availability rate, performance index, and quality index for the same type of equipment, and a pie chart of equipment health status. The equipment health status is statistically displayed based on data directly obtained from the health evaluation system.

[0074] This application can accurately calculate various data on equipment operating efficiency and comprehensively identify problems of equipment time loss; that is, it provides a scientific and accurate reference standard for the original water pump station operation and maintenance management personnel to evaluate the equipment and find out the reasons behind the reduction in equipment availability.

[0075] The solution described in this application is something that traditional solutions cannot achieve. When analyzing time loss, although the operating efficiency value of traditional solutions also decreases, the decrease is relatively slow, so it cannot reflect the time loss problem of the equipment in a timely manner, which will inevitably cause greater economic losses. This is what this invention strives to avoid.
