It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the type, scope of use, and usage scenarios of the personal information involved in the present disclosure should be informed to the user in an appropriate manner in accordance with relevant laws and regulations and the user's authorization should be obtained.

[0052] First, the application scenario of the present disclosure is explained. In the field of hydropower, the cooler of a hydro-turbine generator set generally includes an air cooler and a bearing cooler. The bearing cooler includes an upper guide bearing, a lower guide bearing, a water guide bearing and a thrust bearing cooler. The number of coolers of a hydro-turbine generator set is as many as dozens. The principle of the cooler is mainly to take away the heat of the air or oil outside the cooling pipe through the cooling water in the cooling pipe to achieve cooling of the generator set. According to the requirements of the maintenance regulations and specifications, during the regular maintenance of the hydro-turbine generator set, all coolers must be subjected to a single pressure resistance leak test, generally with a pressure resistance of 0.5MPa for 60 minutes. The purpose is to detect whether the cooler has a leakage defect. If a leak occurs, it must be immediately handled to eliminate the defect to ensure that the hydro-turbine generator set can operate safely and stably.

[0053] The purpose of the present disclosure is to solve the problem of low efficiency of the existing pressure leakage test method for the cooler of the turbine generator set, avoid the method of removing the inlet and outlet pipes of each cooler and filling the coolers with water one by one for pressure leakage test, improve the efficiency of the pressure leakage test of the cooler of the turbine generator set, improve the level of maintenance management of the hydropower station, and increase the power generation of the turbine generator set. The present disclosure is described below in conjunction with specific embodiments.

[0054] Figure 1 FIG. 1 is a schematic diagram of a cooler pressure leak detection test system according to an exemplary embodiment. Figure 1 As shown, an embodiment of the present disclosure provides a cooler pressure leakage detection test system, which may include: a cooler pressure leakage detection test branch 10, a main valve branch 20, a pressurization branch 30 and a data acquisition and controller 40.

[0055] The cooler pressure leak test branch 10 is connected to the main valve branch 20 and the pressurized branch 30 through a pressure-resistant pipeline, and is used to perform a pressure leak test on the cooler. The main valve branch 20 includes a first main valve branch 201 and a second main valve branch 202. The first main valve branch 201 is arranged at the side of the water inlet, and the first main valve branch 201 is respectively connected to the cooler pressure leak test branch 10 and the pressurized branch 30, and is used to control the water inlet of the system. The second main valve branch 202 is arranged at the side of the drain outlet, and the second main valve branch 202 is connected to the cooler pressure leak test branch 10, and is used to control the drainage of the system.

[0056] One end of the pressurizing branch 30 is connected to the water inlet, and the other end is connected to the cooler pressure leak test branch 10, which is used to pressurize the system. The data acquisition and controller 40 is connected to each branch through a communication line to control the valve status of each branch and collect pipeline pressure data.

[0057] It should be noted that the solid line in the figure represents the pressure-resistant pipeline, and the dot-dashed line represents the communication line.

[0058] Exemplarily, all valves are in an open state by default, which does not affect the normal operation of the cooler 103. When it is necessary to perform a pressure leak test on the cooler 103, it is only necessary to control the relevant valves of the cooler pressure leak test branch 10 to be closed, and to judge whether the pressure resistance of the cooler 103 is normal by reading the pressure data of the relevant pressure sensor of the cooler pressure leak test branch 10, so as to detect whether there is a leakage problem in the cooler 103. Since it is not necessary to remove the water inlet and outlet pipes of the cooler 103, and then temporarily install valves and pressure sensors to perform the pressure leak test, the test time and labor costs are greatly saved, and the efficiency of the pressure leak test is improved; in addition, the data acquisition and controller 40 can realize automatic control of the valve, automatic reading of the pressure data, and automatic judgment of the test results, which further saves time and labor, and further improves the efficiency of the pressure leak test of the cooler 103.

[0059] In summary, the embodiment of the present disclosure provides a cooler pressure leakage test system, the system comprising: a cooler pressure leakage test branch, a main valve branch, a pressurization branch and a data acquisition and controller; the cooler pressure leakage test branch is connected to the main valve branch and the pressurization branch through a pressure-resistant pipeline, and is used to perform a pressure leakage test on the cooler; the main valve branch comprises a first main valve branch and a second main valve branch, the first main valve branch is arranged on the side of the water inlet, and the first main valve branch is respectively connected to the cooler pressure leakage test branch and the main valve branch.

Exemplarily, the first valve 101 and the second valve 105 can be electric valves. Using the first pressure sensor 102 and the second pressure sensor 104 dual pressure sensors to collect pipeline pressure data can obtain more accurate data, avoid the failure of a single sensor, resulting in errors in the read pressure data, and causing inaccurate pressure leak test results of the cooler 103.

[0061] In some embodiments, the first main valve branch 201 includes: a first main valve 2011 and a first main valve pressure sensor 2012 connected in sequence through a pressure-resistant pipeline.

[0063] In some embodiments, the pressurizing branch 30 includes: a pressurizing pump 301.

[0064] In some embodiments, the system further includes: a safety branch 50.

The safety branch 50 is connected to the data acquisition and controller 40 through a communication line, and is used to open the gate to reduce pressure when the pressure of the system exceeds the standard.

[0066] In some embodiments, there are multiple cooler 103 withstand voltage leakage test branches 10, and the multiple cooler 103 withstand voltage leakage test branches 10 are connected in parallel. In this way, withstand voltage leakage tests of multiple coolers 103 can be performed simultaneously, further improving the test efficiency.

[0067] In some embodiments, all valves are in an open state by default, so as not to affect the normal operation of the cooler 103.

[0068] In summary, the embodiment of the present disclosure provides a cooler pressure leakage test system, the system comprising: a cooler pressure leakage test branch, a main valve branch, a pressurization branch and a data acquisition and controller; the cooler pressure leakage test branch is connected to the main valve branch and the pressurization branch through a pressure-resistant pipeline, and is used to perform a pressure leakage test on the cooler; the main valve branch comprises a first main valve branch and a second main valve branch, the first main valve branch is arranged on the side of the water inlet, and the first main valve branch is respectively connected to the cooler pressure leakage test branch and the main valve branch. The test branch is connected to the pressurization branch to control the water inlet of the system; the second main valve branch is arranged on one side of the drain outlet, and the second main valve branch is connected to the cooler pressure leakage test branch to control the drainage of the system; one end of the pressurization branch is connected to the water inlet, and the other end is connected to the cooler pressure leakage test branch to pressurize the system; the data acquisition and controller is connected to each of the branches through a communication line to control the valve state of each branch and collect pipeline pressure data. The disclosed embodiment can improve the efficiency of the cooler pressure leakage test.

[0069] Figure 2 FIG. 1 is a flow chart showing a method for testing a cooler's pressure leak detection according to an exemplary embodiment. Figure 2 As shown, the embodiment of the present disclosure provides a cooler pressure leakage test method, the method may include the following steps:

[0070] In step S10 , the first main valve and the second main valve of the main valve branch 20 are controlled to be closed.

[0071] In this step, the data acquisition and controller 40 controls the first main valve 2011 and the second main valve 2022 of the main valve branch 20 to close.

[0072] In step S20, the booster pump of the booster branch is controlled to start working, and the pipeline pressure is obtained through the first main valve pressure sensor and / or the second main valve pressure sensor.

[0073] In this step, the data acquisition and controller 40 controls the booster pump 301 of the booster branch 30 to start working, and obtains the pipeline pressure through the first main valve pressure sensor 2012 and / or the second main valve pressure sensor 2021. In this way, using the first main valve pressure sensor 2012 and the second main valve pressure sensor 2021 to collect pipeline pressure data can obtain more accurate data, avoid the failure of a single sensor, resulting in errors in the read pressure data, and causing inaccurate overall pressure resistance leak detection test results.

[0074] In step S30, when the pipeline pressure reaches the test pressure threshold, the booster pump is controlled to be turned off.

[0075] In this step, when the pipeline pressure reaches the test pressure threshold, the data acquisition and controller 40 controls to turn off the pressure pump 301. For example, the test pressure threshold may be 0.5 MPa.

[0076] In step S40, the first valve and the second valve of the cooler pressure leak test branch 10 are controlled to be closed, and the first pressure value of the branch is obtained through the first pressure sensor and / or the second pressure sensor.

[0077] In this step, the data acquisition and controller 40 controls the closing of the first valve 101 and the second valve 105 of the pressure leak test branch 10 of the cooler 103, and obtains the first pressure value of the branch through the first pressure sensor 102 and / or the second pressure sensor 104.

[0078] In step S50, after waiting for a preset test time, a second pressure value of the branch is obtained through the first pressure sensor and / or the second pressure sensor.

[0079] In this step, after the data acquisition and controller 40 waits for a preset test time, it obtains the second pressure value of the branch through the first pressure sensor 102 and / or the second pressure sensor 104. Exemplarily, the preset test time may be 60 minutes.

[0080] In step S60, when the branch first pressure value is equal to the branch second pressure value, it is determined that the cooler has normal pressure resistance.

[0081] In this step, when the first branch pressure value is equal to the second branch pressure value, the data acquisition and controller 40 determines that the cooler 103 has a normal pressure resistance, that is, the cooler 103 does not have a leakage problem.

[0082] In step S70, when the branch first pressure value is not equal to the branch second pressure value, it is determined that the cooler pressure resistance is abnormal.

[0083] In this step, when the first branch pressure value is not equal to the second branch pressure value, the data acquisition and controller 40 determines that the pressure resistance of the cooler 103 is abnormal, that is, the cooler 103 has a leakage problem.

[0084] Figure 3 FIG. 1 is a flow chart showing a method for testing a cooler's pressure leak detection according to an exemplary embodiment. Figure 3 As shown, the method may further include the following steps:

[0085] In step S80, when the pipeline pressure is greater than a safety pressure threshold, the safety valve of the safety branch is controlled to open to reduce pressure, and the safety pressure threshold is greater than the test pressure threshold.

[0086] In this step, the data acquisition and controller 40 controls the safety valve 501 of the safety branch 50 to open and reduce pressure when the pipeline pressure is greater than the safety pressure threshold, and the safety pressure threshold is greater than the test pressure threshold. Exemplarily, in step 30, if the data acquisition and controller 40 fails to control the closing of the booster pump 301 when the pipeline pressure reaches the test pressure threshold, or the booster pump 301 fails and continues to work without responding to the closing instruction, the pipeline pressure may exceed the standard, and the consequences will be serious if the pressure is not reduced. At this time, the data acquisition and controller 40 controls the safety valve 501 of the safety branch 50 to open and reduce pressure, so as to protect the system from damage.
