Description

Technical Field

[0001] The present invention relates to the technical field of water softening equipment, and in particular to a performance detection method, device, electronic equipment and storage medium for water softening equipment. Background Art

[0002] A water softener is a household appliance that softens hard tap water, improving the quality of household water. It works by exchanging sodium cations with calcium and magnesium ions in tap water through an exchange resin, thereby absorbing excess calcium and magnesium ions and softening the water.

[0003] Water softening equipment must meet certain performance requirements before leaving the factory. For example, the flow rate (pressure drop) of water flowing through the softener's channels at a certain temperature must meet specified requirements. In laboratory testing environments, during the development of a water softener, both the test water temperature and the test environment temperature fluctuate with the seasons, affecting the water flow rate and, in turn, the performance verification of the softening equipment. This requires significant investment to control the water temperature within a certain range in order to verify the performance of the softening equipment. Without temperature control equipment, the performance verification process for the softening equipment cannot be fully and accurately completed. Summary of the Invention

[0058] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0059] It should be noted that with the improvement of living standards, people are paying more and more attention to household water use. There are now more and more water softeners on the market. Water softeners can replace calcium and magnesium ions in water with sodium ions, softening high-hardness water into soft water, extending the service life of water-related equipment, and having beauty, skin care, and clothing care effects.

[0060] In order for the softening equipment to operate and meet its performance requirements, the necessary physical conditions to be guaranteed are (temperature, pressure, and flow rate). The water softeners currently sold on the market only have a flow sensor to monitor the flow rate, but do not monitor the two key physical conditions of temperature and pressure in real time. At the same time, in the laboratory test environment, during the development of the water softener, the test water temperature and the test environment temperature will change with the change of seasons, which will affect the water flow rate and thus affect the performance verification of the softening device. The investment amount for investing in a set of equipment that can control the temperature and meet the hardness standard is over one million. Companies are often reluctant to invest in such expensive temperature control equipment, resulting in a lack of completeness and accuracy in the laboratory's verification process of the water softener's performance.

[0061] Please refer to Figure 1 The embodiment of the present invention provides a performance detection method for a water softening device, which may include the following steps:

[0062] S1. Obtaining the corresponding relationship between water temperature and pressure drop of the target flow channel;

[0063] S2. determining a target pressure drop value corresponding to the current test water temperature based on the correspondence between the water temperature and the pressure drop;

[0064] S3. Determine a performance test result based on a numerical relationship between the actual pressure drop value and the pressure drop target value;

[0065] The target flow channel is the flow channel between the water inlet and the water outlet of the water softening device; and the actual pressure drop value is the pressure drop value of the target flow channel at the current test water temperature.

[0066] It is understandable that the pressure drop value is equivalent to the water pressure loss in the pipeline. For example, for the target pipeline between the water inlet and the water outlet of the water softener, under certain constant conditions (fixed water flow rate and fixed temperature), the difference between the water pressure value measured near the water inlet and the water pressure value measured at the water outlet is the pressure drop value under the constant conditions. Since the pressure drop value of the water softener flow channel will affect the water consumption of the user's household water main, in order to minimize the impact of the use of the water softener on the water consumption of the main pipeline, in theory, the pressure drop value of the water softener flow channel should be as small as possible within a certain range. In addition, considering the user's experience, the water outlet impulse of the water softener needs to be controlled within a certain range, not too high or too small. A better water outlet impulse reference value can be obtained through a large number of user test verifications. Based on this water outlet impulse reference value, the water pressure value corresponding to the outlet can be calculated, and then the standard pressure drop value between the water inlet and outlet of the water softener can be determined.

[0067] It should be noted that, at the rated flow rate, since the fluidity of water at different temperatures is different, the standard pressure drop values ​​corresponding to different temperatures are also different. Therefore, in order to verify whether the water output impulse of the water softener meets the set standard, it is necessary to verify the flow channel pressure drop values ​​at different temperatures. In an embodiment of the present invention, the standard pressure drop values ​​corresponding to different temperature values ​​at the rated flow rate are first obtained, wherein the standard pressure drop values ​​can be pre-tested and verified multiple times. Based on these different temperature values ​​and different standard pressure drop values, the corresponding relationship between water temperature and pressure drop can be determined, and the current test water temperature of the laboratory (the temperature of the water body used to detect the flow channel performance of the water softener) is measured. The current test water temperature is matched with the temperature-pressure correspondence (the corresponding relationship between water temperature and pressure drop), and the pressure drop target value at the current test water temperature can be obtained. That is, when the target pipeline is tested at the rated flow rate using the water body at the current test water temperature, the pressure drop target value should be used as the basis for whether the test verification is passed. At the current test water temperature, water is introduced into the water softening equipment at the rated flow rate, and the actual pressure drop value of the target pipeline is measured (the difference between the water pressure at the water inlet and the water pressure at the water outlet). The performance test result is determined based on the numerical relationship between the actual pressure drop value and the pressure drop target value. For example, if the measured actual pressure drop value is higher than the pressure drop target value by a certain value, it indicates that the performance test of the target pipeline of the water softening equipment has failed.

[0068] The performance testing method for a water softener according to an embodiment of the present invention can match a corresponding pressure drop target value for any temperature in the test environment by obtaining the corresponding relationship between temperature and pressure drop, thereby enabling complete and accurate performance testing and verification of the flow path of the water softener.

[0069] In one embodiment, step S1 may include:

[0070] S11 . Fitting a pre-stored temperature-pressure correspondence table of a target flow channel to obtain a correspondence between the water temperature and the pressure drop of the target flow channel.

[0071] In an embodiment of the present invention, a pre-stored temperature-pressure correspondence table of a target flow channel can be fitted to obtain the correspondence between the water temperature and the pressure drop of the target flow channel, wherein the temperature-pressure correspondence table records multiple temperature values ​​and corresponding reference pressure drop values. These reference pressure drop values ​​can be calibrated through repeated experimental verification at the rated flow rate. First, these existing temperature and pressure drop values ​​are marked in a coordinate system, and then these marked points are fitted to obtain the correspondence between the water temperature and the pressure drop of the target flow channel. It can be understood that fitting refers to connecting a series of points on a plane with a smooth curve. Because this curve has countless possibilities, there are various fitting methods. Commonly used fitting methods include least squares curve fitting. Fitting, interpolation, and approximation are the three basic tools of numerical analysis. In a popular sense, they differ in that: fitting is a known point sequence and approaches them as a whole; interpolation is a known point sequence and passes through the point sequence completely; approximation is a known curve or point sequence, and through approximation, the constructed function is infinitely close to them.

[0072] The performance testing method for a water softener according to an embodiment of the present invention obtains a target pressure drop value corresponding to any temperature value by fitting the values ​​of a temperature-pressure correspondence table. This eliminates the need to use expensive temperature control equipment to control the test water temperature at a certain temperature in order to obtain the corresponding target pressure drop value from the temperature-pressure correspondence table. Thus, the flow channel performance of the water softener can be completely and accurately verified without using a temperature control device.

[0073] In one embodiment, step S11 may include:

[0074] S111, obtaining a linear regression equation of water temperature and pressure drop based on a plurality of conventional water temperature values ​​in the temperature-pressure correspondence table and a plurality of reference pressure drop values ​​corresponding to the plurality of conventional water temperature values;

[0075] Determining the corresponding relationship between the water temperature and the pressure drop based on the linear regression equation;

[0076] The reference pressure drop value is the pressure drop value of the target flow channel at the corresponding normal water temperature.

[0077] It should be noted that, based on multiple sets of data with certain regularities, corresponding functional relationships can be derived based on the independent variables and dependent variables of the multiple sets of data. In an embodiment of the present invention, multiple conventional water temperature values ​​in the temperature-pressure correspondence table can be used as independent variables, and the reference pressure drop values ​​corresponding to each conventional water temperature value can be used as dependent variables to obtain their linear regression equations, thereby achieving a linear fit of the temperature-pressure correspondence table, and then obtaining the corresponding pressure drop target value at any temperature value through the linear regression equation.

[0078] The performance testing method for a water softener according to an embodiment of the present invention obtains a target pressure drop value at any temperature by calculating a corresponding linear regression equation based on the numerical values ​​in the temperature-pressure correspondence table. This method eliminates the need for expensive temperature control equipment to control the test water temperature at a certain temperature in order to obtain the corresponding target pressure drop value from the temperature-pressure correspondence table. Therefore, the flow channel performance of the water softener can be completely and accurately verified without the use of a temperature control device.

[0079] In one embodiment, step S3 may include:

[0080] It is determined that the absolute value of the difference between the actual pressure drop value and the pressure drop target value is greater than a preset threshold, and a performance test result indicating that the pressure drop performance is unqualified is determined.

[0081] It should be noted that the pressure drop across the softener's flow path affects the user's household water mains. To minimize the impact of the softener's use on mains water consumption, theoretically, the smaller the pressure drop across the softener's flow path, the better, within a certain range. Furthermore, considering the user experience, the softener's water output impulse must be controlled within a certain range. Excessively high or low water output impulses can negatively impact the user experience. Therefore, a suitable reference value for water output impulse can be obtained through extensive user testing. Based on this reference value for water output impulse, the water pressure corresponding to the water outlet can be calculated, thereby determining the target pressure drop between the softener's inlet and outlet. In this embodiment of the present invention, the target pressure drop corresponding to the rated flow rate and the current test temperature is first obtained. During the test, the actual pressure drop across the softener's flow path is then collected and calculated. The performance test result is then determined based on the difference between the actual pressure drop and the target pressure drop, compared to a threshold. It can be understood that if the difference between the actual pressure drop value and the pressure drop target value is greater than the threshold, it means that the actual pressure drop value at the rated flow rate and current temperature is too large or too small, resulting in a poor user experience, and it is judged that the pressure drop performance is unqualified and does not meet the product requirements.

[0082] The performance testing method for a water softener according to an embodiment of the present invention further improves the accuracy of performance verification of the flow channel of the water softener by determining that a large difference between the actual pressure drop value and the pressure drop target value is a failure in the pressure drop performance test.

[0083] In one embodiment, after step S3, the method may further include the following steps:

[0084] S4. adjusting the simulation model of the target flow channel based on the performance test results;

[0085] Wherein, adjusting the simulation model of the target flow channel includes at least one of the following:

[0086] Adjusting the simulation model of the target flow channel by adjusting the flow resistance parameter of the target flow channel;

[0087] The simulation model of the target flow channel is adjusted by adjusting the size parameters of the water inlet pipe of the target flow channel.

[0088] It should be noted that the performance test results may include information on whether the pressure drop performance test is qualified or unqualified, as well as information on whether the pressure drop is too large or too small. Based on the performance test results, the simulation model of the target flow channel can be adjusted and optimized. It is understandable that the pressure drop value of the target flow channel reflects the pressure loss at the inlet and outlet of the flow channel. If the actual pressure drop value is too large, it means that the pressure loss of the flow channel is too much, which will cause a significant impact on the water supply of the user's home main pipeline. The pressure drop needs to be reduced to meet the performance requirements. Correspondingly, if the actual pressure drop value is too small, it means that the pressure loss of the flow channel is too small, which will cause the water output impulse of the water softener to be too large, affecting the user's experience. The pressure drop needs to be increased to meet the performance requirements. It should be noted that the pressure drop of the flow channel is related to the flow resistance inside the water softener and the thickness of the water inlet pipe. Therefore, the pressure drop value can be adjusted by adjusting the flow resistance parameters and / or the water inlet pipe size parameters of the target flow channel.

[0089] The performance testing method for a water softening device according to an embodiment of the present invention adjusts the simulation model of the target flow channel by adjusting the flow resistance parameters and / or the water inlet pipe size parameters, so that the optimization process of the flow channel performance can be intuitively perceived during the test, thereby improving the efficiency of performance verification of the flow channel of the water softening device.

[0090] In one embodiment, step S4 may include:

[0091] Determine that the actual pressure drop value is greater than the target pressure drop value, and perform at least one of the following:

[0092] adjusting the simulation model of the target flow channel by reducing the flow resistance parameter of the target flow channel;

[0093] Adjusting the simulation model of the target flow channel by increasing the size parameter of the water inlet pipe of the target flow channel;

[0094] Determine that the actual pressure drop value is less than the target pressure drop value, and perform at least one of the following:

[0095] adjusting the simulation model of the target flow channel by increasing the flow resistance parameter of the target flow channel;

[0096] The simulation model of the target flow channel is adjusted by reducing the size parameters of the water inlet pipe of the target flow channel.

[0097] It should be noted that when the pressure drop performance test fails, the flow resistance of the target flow channel or the size of the water inlet pipe needs to be adjusted, and the specific parameter adjustment direction can be further determined based on the numerical relationship between the actual pressure drop value and the pressure drop target value. It can be understood that the pressure drop of the flow channel is related to the flow resistance inside the water softener and the thickness of the water inlet pipe. Specifically, when the water inlet pipe is fixed, the greater the flow resistance of the flow channel, the greater the pressure drop of the flow channel; when the flow resistance parameter of the flow channel is fixed, the larger the water inlet pipe, the smaller the pressure drop of the flow channel. Based on the above relationship between the flow channel pressure drop, the flow resistance parameter and the size of the water inlet pipe, the specific parameter adjustment direction can be determined. After determining the adjustment direction, the parameter can be adjusted according to the preset fixed value, or the adjustment value can be determined according to the specific difference between the actual pressure drop value and the pressure drop target value.

[0098] The performance detection method of the water softening equipment in an embodiment of the present invention adjusts the simulation model of the target flow channel by reducing the flow resistance parameter of the target flow channel and / or increasing the size parameter of the water inlet pipe of the target flow channel when the actual pressure drop value is too large; when the actual pressure drop value is too small, the simulation model of the target flow channel is adjusted by increasing the flow resistance parameter of the target flow channel and / or decreasing the size parameter of the water inlet pipe of the target flow channel, thereby achieving accurate verification and optimization of the flow channel of the water softening equipment.

[0099] See Figure 2-4 Based on the above scheme, in order to better understand the performance detection method of the water softening equipment provided by the embodiment of the present invention, the following specific examples are given for detailed description:

[0100] In this embodiment of the present invention, a temperature and pressure sensor can be installed in the water path of the control valve to monitor the water temperature and pressure in the water softener's flow path in real time. This information can then be transmitted to the user via an app. Furthermore, based on the effect of the collected water temperature on flow rate, a water temperature fit curve can be calculated using the Minitab Normal Distribution Plot tool, a 6 Sigma tool.

[0101] 1. Temperature and pressure comparison table at rated flow rate:

[0102] a. Close the bypass valve or mixing valve, measure the nominal flow rate after the water softener automatically regenerates, and determine the rated flow rate;

[0103] b. Connect the softener to a hard water supply at a pressure of 400 kPa;

[0104] c. Measure the pressure drop of the softener at different flow rates and measure the water temperature at the same time;

[0105] d. The nominal flow rate refers to the flow rate when the measured pressure drop and water temperature are equal to the temperature-pressure correspondence table given in the table below. When the water temperature exceeds the range given in the table below, it is necessary to use the temperature-pressure fit formula to calculate the flow rate.

[0106] Water temperature (℃) Pressure drop corresponding to rated flow rate (kPa) 5 135 6 132 7 127 8 122 9 119 10 115 11 111 12 109 13 105 14 103 15 100 16 97 17 95 18 93 19 91 21 86 22 85 23 83 24 81 25 79

[0107] It is understandable that, in addition to the corresponding relationship between temperature and pressure drop listed in the above table, different corresponding relationships between temperature and pressure drop can be obtained under other preset rated flow rates.

[0108] Second, obtain the temperature and pressure values ​​in the flow channel through the integrated temperature and pressure sensor:

[0109] Based on the change in voltage under different pressures, the pressure value in the detection pipeline is logically calculated. As an example, the parameter information of the temperature and pressure integrated sensor can be shown in the following table:

[0110]

[0111]

[0112] The integrated temperature and pressure sensor can detect the temperature and pressure of water in the pipe according to the change of voltage under different pressures through logical calculation. The relationship between the output voltage and pressure value of the sensor can be expressed as Figure 2 The output curve of the output curve can be expressed as: Vout = 0.35 + 1.469P, where Vout represents the output voltage and P represents the corresponding pressure value. Therefore, the corresponding relationship between the output voltage and the pressure value can be shown in the following table:

[0113] <![CDATA[P(i n MP a )]]> 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5 1.6 Vout 0.35 0.49 0.64 0.79 0.93 1.08 1.23 1.38 1.52 1.67 1.82 1.96 2.11 2.26 2.4 2.55 2.7

[0114] In the embodiment of the present invention, based on the known temperature and pressure drop values ​​in the temperature-pressure correspondence table, the regression formula for water temperature and pressure drop can be calculated using the "minitab normal distribution chart" of the 6 Sigma tool. Press F1 in the Minitab tool to obtain relevant help. Regression analysis is performed based on the Pareto chart of the component and the Pareto chart of the model: the corresponding relationship between the pressure drop (kPa) and the water temperature (°C) corresponding to the rated flow rate, and its regression equation is:

[0115] Pressure drop corresponding to rated flow rate (kPa) = 143.9-2.743 water temperature (℃);

[0116] The output analysis results are as follows:

[0117] S=2.72204R-Sq=97.7%R-Sq(adjusted)=97.5%;

[0118] ANOVA:

[0119]

[0120] Among them, SS is the sum of squares, MS is the mean sum of squares, obtained by ss / df, F is the F statistic, such as F(part) = ms(part) / ms(part*oper) in the interaction analysis, and P is the significance probability, which is used to judge significance.

[0121] Fitting line: Polynomial regression analysis is performed on the pressure drop (kPa) and water temperature (°C) corresponding to the rated flow rate, and the regression equation is:

[0122] Equation 1: Pressure drop corresponding to rated flow rate (kPa) = 158.1 - 5.005 water temperature (°C) + 0.07521 water temperature (°C)^2; the fitting curve is as follows Figure 3 As shown;

[0123] Equation 2: Pressure drop corresponding to rated flow rate (kPa) = 163.8 - 6.481 water temperature (°C) + 0.1848 water temperature (°C)^2 - 0.002441 water temperature (°C)^3; the fitting curve is as follows Figure 4 shown.

[0124] The fit of the square of equation 1 and the fit of the cubic of equation 2 are both very good, and according to the 6 Sigma quality control standard, both reach a 95% confidence interval. These two equations can be used as the corresponding relationship between water temperature and pressure drop.

[0125] Compared with the prior art, the embodiment of the present invention calculates the linear regression equation of water temperature and pressure drop as the basis for verifying the pressure drop performance of the water softener flow channel, thereby achieving complete and accurate verification of the water softener performance without using temperature control equipment.
