[0034] Figure 1 Schematic diagram of the structure of a fuel supply unit test device provided by the present invention. This embodiment can be applied to the situation of fast, simple, efficient, low-cost and instant testing of the fuel supply unit to be tested. Figure 1 The device specifically includes: a test condition simulation module 101, an information processing module 102, a raw material supply module 103, a power module 104 and an information detection module 105.

[0035] from Figure 1 It can be seen that the information processing module is respectively connected to the information detection module, the power module, the raw material supply module and the fuel supply unit to be tested, and the fuel supply unit to be tested is respectively connected to the test condition simulation module, the power module, the raw material supply module and the information detection module. Specifically, the test condition simulation module is used to generate test control information according to the test requirements input by the user, and send the test control information to the target controlled module so that the target controlled module runs based on the test control information, wherein the test control information includes power control information, fuel unit control information and raw material control information, and the target controlled module includes a power module, a fuel supply unit to be tested and a raw material supply module; the information detection module is used to determine the operating parameters of the fuel supply unit to be tested after the target controlled module runs based on the test control information, and send the operating parameters to the information processing module so that the information processing module determines the test report of the fuel supply unit to be tested based on the operating parameters.

[0036] The information processing module can be understood as a processor with information processing, solving and transmission capabilities. The test equipment of the fuel supply unit can be transported with the fuel supply unit to be tested. When there is a test requirement for the fuel supply unit to be tested, the fuel supply unit to be tested is connected to the test equipment of the fuel supply unit in the above-mentioned connection method. The test equipment of the fuel supply unit can be used to test the performance of the fuel supply unit to be tested and give a performance diagnosis conclusion, thereby saving the testing cost of the fuel supply unit to be tested, shortening the testing time of the fuel supply unit to be tested, and improving the testing efficiency and simplicity of the fuel supply unit to be tested.

[0037] When performing performance testing, it is necessary to test the operation of the fuel supply unit to be tested under at least one operating condition. The test requirements can be understood as the parameters of the operating conditions, including but not limited to ambient temperature, operating mode, power, interval working time and total working time. The test control information can be understood as the operating parameters of the target controlled module. The target controlled module can be understood as the equipment or components that need to perform auxiliary work when verifying the performance of the fuel supply unit to be tested. The operating parameters of the fuel supply unit to be tested can be understood as the status information of the fuel supply unit to be tested when it is working, including but not limited to flow information, pressure information and temperature information. The test report can be understood as the test conclusion of the fuel supply unit to be tested. It is worth noting that when the test conclusion indicates that there is an abnormality in the fuel supply unit to be tested, the test report also includes the cause of the abnormality and the abnormality handling plan, so that the debugging personnel can handle the abnormality of the fuel supply unit to be tested.

[0038] Figure 2 It is a structural schematic diagram of another fuel supply unit testing device provided by the present invention, and some components are Figure 2 Not shown, see Figure 2 , the power module 104 includes a compressed air unit 1041, a filter 1042 and a dryer 1043. The raw material supply module 103 includes a gravity water tank 1031, a water tank rack, a raw material unit 1032 and a three-way valve 1033. The water tank rack (not shown in the figure) is used to carry and support the gravity water tank 1031. The test equipment also includes a discharge module 111, and the test condition simulation module 101 includes an information interaction unit 1011 and a control unit 1012. The fuel supply unit to be tested is externally arranged with a nitrogen interface 107, an instrument control air interface 106, a fuel inlet 108, a fuel outlet 109 and a fuel discharge outlet 110.

[0039] Combination Figure 2 It can be seen that:

[0040] 1) The first end of the filter is connected to the output end of the compressed air unit through a gas transmission pipe, the second end of the filter is connected to the first end of the dryer and the nitrogen interface of the fuel supply unit to be tested through the gas transmission pipe, and the second end of the dryer is connected to the instrument control air interface of the fuel supply unit to be tested through the gas transmission pipe; the compressed air unit is used to provide a first gas source, the filter is used to filter impurities in the first gas source to obtain a second gas source, the dryer is used to dry the compressed air in the second gas source to obtain a third gas source, the second gas source is used to determine the sealing of the test equipment of the fuel supply unit, and the third gas source is used to provide operating power for the raw material supply module and the fuel supply unit to be tested. The purpose of this setting is to use dry compressed air as the gas source to drive the pneumatic remote control valve to realize the raw material circulation of the test equipment, and it can also simulate nitrogen purge test equipment to determine the sealing of the test equipment to ensure the safety and reliability of the test environment and test conclusions.

[0041] 2) The water outlet of the gravity water tank is connected to the first end of the three-way valve through a liquid transmission pipe, the output end of the raw material unit is connected to the second end of the three-way valve through a liquid transmission pipe, the third end of the three-way valve is fixedly connected to the fuel inlet of the fuel supply unit to be tested or connected to the fuel inlet of the fuel supply unit to be tested through a liquid transmission pipe, and the fuel outlet of the fuel supply unit to be tested is connected to the water inlet of the gravity water tank through a liquid transmission pipe; the gravity water tank and the raw material unit are used to provide test raw materials for the fuel supply unit to be tested so that the fuel supply unit to be tested can be operated. The test raw materials of the present invention are tap water, marine methanol, or liquids that match the material parameters of marine methanol. The advantage of such a setting is that the test scheme of the fuel supply unit to be tested can be dynamically adjusted according to the test environment, thereby ensuring that the test work of the fuel supply unit to be tested can be carried out normally. Exemplarily, when the test raw material is tap water, the raw material unit can be a normally operating tap water pipe or reservoir. At startup, there is no raw material in the gravity water tank. The principle unit provides the test raw material for the fuel supply unit to be tested. The test raw material is circulated and will circulate to the gravity water tank. When the liquid level of the test raw material in the gravity water tank reaches the preset liquid level, the raw material supply work of the raw material unit will be stopped. Only the test raw material in the gravity water tank can be used to complete the test work. The advantage of this setting is that it can greatly reduce the waste of test raw materials. When the liquid level of the test raw material in the gravity water tank does not reach the preset liquid level, a dual-circuit raw material supply or a raw material unit raw material supply method can be used. The preset liquid level and raw material supply logic are related to the principle of the test scheme, and this embodiment does not limit this. Secondly, the diameter of the liquid transmission pipe is larger than the diameter of the gas transmission pipe. The advantage of this setting is that the liquid level of the test raw material in the gravity water tank can quickly reach the preset liquid level, so that the test environment is in a stable state.

[0042] Furthermore, the fuel supply unit to be tested may be a marine methanol fuel supply unit, and the test equipment of the fuel supply unit may be used to test the performance of the marine methanol fuel supply unit. The test equipment of the fuel supply unit of the present invention may be independently operated outside the test workshop, for example, by using tap water to perform the test in an area other than the test workshop, and does not require the use of methanol fuel for the performance test, which can effectively reduce the cost and danger of the test work.

[0043] 3) The discharge module is connected to the fuel discharge outlet of the fuel supply unit to be tested and the information processing module respectively, and is used to discharge the retained gas and retained liquid of the fuel supply unit to be tested when receiving the discharge instruction sent by the information processing module, so as to keep the fuel supply unit to be tested in a dry state. The discharge module is generally used after the test work is completed. The discharge instruction is used to indicate the end of the test work. After the test work is completed, the retained gas and liquid of the fuel supply unit to be tested are discharged to keep the fuel supply unit to be tested in a dry state, extend the service life of the equipment, and reduce the probability of rust.

[0044] It is worth noting that the operation of each component is controlled by the test control information issued by the test condition simulation module, that is, each component will receive the test control information issued by the test condition simulation module in real time during operation and dynamically adjust its operating parameters.

[0045] Specifically, the information interaction unit is used to display the operating condition parameter determination interface, and receive the test requirements input by the user based on the operating condition parameter determination interface; the control unit is used to generate power control information, fuel unit control information and raw material control information according to the test requirements, and send power control information to the power module, send raw material control information to the raw material supply module, and send fuel unit control information to the fuel supply unit to be tested, so that the power module operates based on the power control information, the fuel supply unit to be tested operates based on the fuel unit control information, and the raw material supply module operates based on the raw material control information.

[0046] Among them, the information interaction unit can be understood as an information interaction screen, which is used to display characteristic information in the test work, including but not limited to information parameter input box, parameter input table, diagnostic results and information filling instructions. The control unit can be understood as a signal acquisition control box, which is used to process user test demand information received by the information interaction unit and parse the controlled modules and control parameters of the controlled modules in the test equipment.

[0047] When the testing device for the fuel supply unit of the present invention is used, a site of a suitable size for a workshop is required to prevent the fuel supply unit to be tested and the testing device from being placed thereon.

[0048] Optionally, the information detection module includes a pressure detector arranged at the fuel outlet of the fuel supply unit to be tested and a flow detector deployed inside the fuel supply unit to be tested; wherein the pressure detector is used to determine the pressure information of the fuel supply unit to be tested; and the flow detector is used to determine the fuel flow information of the fuel supply unit to be tested.

[0049] Specifically, the pressure qualified range and fuel flow qualified range of the fuel supply unit to be tested are different under different working conditions, and different parameter abnormalities represent different performance failures. After determining the pressure information and fuel flow information of the fuel supply unit to be tested, the present invention can compare them with the parameter qualified range of the current working condition, and determine the performance diagnosis result of the fuel supply unit to be tested according to the comparison result.

[0050] For example, assuming that the fuel flow rate information exceeds the qualified range, it represents A abnormality, the fuel flow rate information is lower than the qualified range, it represents B abnormality, the pressure information exceeds the qualified range, it represents C abnormality, and the pressure information is lower than the qualified range, it represents D abnormality. According to the matching results of the detection data, the performance diagnosis results of the fuel supply unit to be tested can be located. It is worth noting that the abnormality detection report will also include the working conditions corresponding to the abnormality. The advantage of this setting is that it is convenient for the commissioning personnel to locate the abnormal position and solve the abnormality.

[0051] After determining the test report of the fuel supply unit to be tested, the information processing module is also used to: determine whether there is an abnormal detection conclusion in the test report; if there is an abnormal detection conclusion in the test report, the control information interaction unit displays the abnormal detection conclusion, and when receiving a re-inspection instruction, updates the test control information based on the re-inspection instruction, wherein the updated test control information is used to re-start the detection work of the fuel supply unit to be tested.

[0052] The re-test instruction is used to indicate to the commissioning personnel that the equipment commissioning has been completed and the test can continue. The advantage of this setting is that the fuel supply unit to be tested can be fully inspected and repaired. Secondly, if the test report indicates that there is no abnormality in the fuel supply unit to be tested, the inspection work is terminated and the equipment self-test procedure is performed. The equipment self-test is to make the function of the test equipment in a stable state so as to perform subsequent inspection work.

[0053] This embodiment designs a portable test device, which can be transported with the fuel supply unit and measure the performance of the fuel supply unit at any time. For example, the test condition simulation module simulates the working condition that needs to be tested, the raw material supply module and the power module cooperate with each other to make the fuel supply unit to be tested operate under the above working condition, the information detection module determines the operating parameters of the fuel supply unit to be tested, and the information processing module determines the test report of the fuel supply unit to be tested according to the operating parameters, which can achieve the purpose of simply, efficiently, safely and at low cost to detect the performance of the fuel supply unit, and is also suitable for testing different displacements and different fuel supply units. It is cost-friendly and not restricted by the site, has high practicality and applicability, and is easy to maintain. It solves the problem that the existing workshop test method cannot test the fuel supply unit that is not in the workshop. Once the fuel supply unit has problems during transportation, various supply condition follow-up tests are required. The fuel supply unit needs to be sent to the end-user equipment factory for joint debugging, or the fuel supply unit needs to be sent to the production workshop for testing. The test cycle is subject to the transportation time, and the safety risk of joint debugging is high, and the cost is difficult to control.

[0054] The present invention also provides a fuel supply unit test system, which can be used for rapid, simple, efficient, low-cost and instant testing of a fuel supply unit to be tested. The system includes: a fuel supply unit to be tested and a test device for any fuel supply unit in the above embodiments.

[0055] The test system of the fuel supply unit in this embodiment includes the test equipment of any one of the fuel supply units in the above embodiments. When there is a detection demand for the fuel supply unit to be tested, the system can use the test equipment of the fuel supply unit to make the fuel supply unit to be tested work under the test condition, measure the operating parameters of the fuel supply unit to be tested, and determine its performance. It is not necessary to transport the fuel supply unit to be tested to the test workshop or the end-user equipment factory, which effectively saves the cost and time of the test work. It solves the problem that the existing workshop test method cannot test the fuel supply unit that is not in the workshop. Once the fuel supply unit has a problem during transportation, it is necessary to carry out various supply condition follow-up tests. Then, the fuel supply unit needs to be sent to the end-user equipment factory for joint debugging, or the fuel supply unit needs to be sent to the production workshop for testing. The test cycle is subject to the transportation time, and the safety risk of joint debugging is high, and the cost is difficult to control. Further, the test system of the fuel supply unit provided in this embodiment includes the test equipment of the fuel supply unit in the above embodiment, and has the corresponding beneficial effects of the test equipment of the above fuel supply unit.

[0056] Figure 3is a flow chart of a device detection method provided by the present invention. This embodiment is used for fast, simple, efficient, low-cost and instant testing of the fuel supply unit to be tested. The device detection method is applied to the test device of the fuel supply unit in any embodiment of the present invention. Figure 3 , the method specifically comprises:

[0057] S101. When the fuel supply unit to be tested is successfully connected to the test equipment of the fuel supply unit, the test equipment of the fuel supply unit is used to simulate at least one working condition to be tested, so that the fuel supply unit to be tested operates under the at least one working condition to be tested.

[0058] The fuel supply unit to be tested may be understood as a fuel supply unit that has a performance test requirement, that is, the fuel supply unit to be tested in the above embodiment.

[0059] S102: Determine the operating parameters of the fuel supply unit to be tested, and determine a test report of the fuel supply unit to be tested according to the operating parameters.

[0060] Similarly, when the test report indicates that the fuel supply unit to be tested is qualified, the test work is terminated and the test equipment is self-checked. When the test report indicates that the fuel supply unit to be tested is unqualified, abnormal test information is sent to the debugging personnel or the abnormal test information is displayed through the interactive interface, prompting the debugging personnel to debug the fuel supply unit to be tested and restart the test work when receiving the re-inspection instruction.
