Description

Technical Field

[0001] This disclosure relates to the technical field of water pump testing, and more specifically, to a water pump leakage testing device. Background Technology

[0002] In related technologies, water pump leakage tests are generally conducted on a test vehicle. This involves draining all the coolant from the vehicle, removing the original water pump, installing the water pump to be tested on the vehicle, connecting all the pipes, adding coolant, starting the vehicle, and waiting for the water temperature to reach the test temperature before circulating the coolant. During the test, the vehicle needs to be lifted multiple times with a lift to check for leaks from underneath. After the test is completed, the test unit needs to be removed and the vehicle restored.

[0003] Disassembling and installing the water pump and adding coolant takes a long time, and the space under the vehicle is narrow, making it difficult to operate and observe. Furthermore, draining coolant is wasteful and results in a loss of manpower and resources. Utility Model Content

[0027] The specific embodiments of this disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0028] In the description of this disclosure, it should be understood that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the drawing orientation shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational construction and operation, and therefore should not be construed as a limitation of this disclosure.

[0029] In this disclosure, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0030] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0031] like Figures 1 to 3As shown, this application provides a water pump leakage test device 100, including a housing 10 and a transmission structure 20. The housing 10 has a water pump mounting structure 11, which includes an opening 111 penetrating the outer wall of the housing 10 and a first connecting part 112 disposed at the opening 111. The first connecting part 112 is located on the outer wall of the housing 10 and is used to connect with a water pump 200. The water pump 200 communicates with the interior of the housing 10 through the opening 111. The transmission structure 20 includes a belt 21, a roller 22 and a drive member 23. The drive member 23 drives the roller 22 to rotate, and the belt 21 is used to connect the roller 22 and the water pump wheel of the water pump 200.

[0032] Through the above technical solution, a water pump leakage testing device 100 is designed to replace the experimental vehicle for testing the leakage of water pump 200. The liquid is contained in a housing 10, which does not need to be drained, thus avoiding waste. Furthermore, the water pump leakage testing device 100 uses a transmission structure 20 to simulate the operating state of water pump 200 on a vehicle, enabling leakage testing of water pump 200 under operating conditions. In this way, the water pump leakage testing device 100 can replace the experimental vehicle to test the leakage of water pump 200, effectively improving the convenience of installation and disassembly of water pump 200, reducing waste of manpower and resources, and facilitating the observation of leakage conditions.

[0033] Using the water pump leakage test device 100 to test the leakage of the water pump 200 instead of the test vehicle avoids the road test required when testing the water pump 200 on the test vehicle. Furthermore, due to its ease of observation, it makes it easier to detect leaks that are difficult to identify. It also avoids potential problems such as improper bolt installation or cylinder block breakage that could occur when installing the water pump 200 on the test vehicle.

[0034] Adding liquid to the tank 10 is more convenient than adding liquid on the test vehicle, which improves the ease of liquid addition and avoids burns caused by gas escaping during the large circulation of coolant when adding liquid on the vehicle. Here, "liquid" refers to coolant.

[0035] Here, the opening 111 is used to connect the interior of the housing 10 with the water pump 200, so as to ensure that the coolant inside the housing 10 can flow through the water pump 200 and the coolant inside the housing 10 flows back to the housing 10 after flowing through the water pump 200.

[0036] In this disclosure, the drive component 23 of the transmission structure 20 serves as the power structure of the transmission structure 20 to drive the roller 22 to rotate. The roller 22 is connected to the water pump wheel of the water pump 200 via a belt 21 to drive the water pump 200 to rotate, thereby simulating the use state of the water pump 200 in a vehicle.

[0037] like Figure 2 and Figure 3As shown, the first connecting portion 112 may include a first connecting surface, and the second connecting portion 220 on the water pump 200 has a second connecting surface. The first connecting surface is used to connect with the second connecting surface, and the contour of the first connecting surface is adapted to match the contour of the second connecting surface. For example, one or both of the shape and size of the first connecting surface are the same as the shape and size of the second connecting surface. This configuration allows for a compatible connection between the water pump 200 and the housing 10, mimicking the connection of the water pump 200 in use on a vehicle as closely as possible, ensuring the reliability of the test results and the stability of the connection between the water pump 200 and the housing 10.

[0038] Optionally, such as Figures 1 to 3 As shown, the water pump leakage test device may further include a sealing gasket 230, which is adapted to be disposed between the water pump mounting structure 11 and the second connection portion 220 of the water pump 200. The outer contour of the sealing gasket 230 is adapted to the water pump mounting structure 11. This can mimic the use of the sealing gasket 230 on a vehicle, ensuring that the leakage test results of the water pump 200 will not be affected by the absence of the sealing gasket 230.

[0039] In this disclosure, such as Figure 1 As shown, the water pump leakage test device 100 may further include a tensioning wheel 30 arranged on the outer wall of the housing 10. The tensioning wheel 30 is connected to the belt 21 and is used to tension the belt 21. The tensioning wheel 30 can ensure that the belt 21 connecting the water pump impeller and the roller 22 of the water pump 200 is in a taut state, preventing the belt 21 from falling off and affecting the rotation of the water pump impeller driven by the roller 22.

[0040] Optionally, there can be multiple pump mounting structures 11, which are used to mount multiple pumps 200. The multiple pumps 200 are connected to each other by belts 21. With this configuration, the pump leakage testing device 100 can test the leakage of multiple pumps 200 simultaneously, which helps to save testing time and improve testing efficiency.

[0041] In this disclosure, a heater may be installed inside the housing 10, and a heating switch 41 electrically connected to the heater is installed on the housing 10. A controller 40 is used to control the start and stop of the heater. Here, the purpose of installing the heater is to heat the coolant passing through the water pump 200 to simulate the temperature of the coolant when the vehicle is in use, so as to reproduce the operating conditions of the water pump 200 in the vehicle as closely as possible.

[0042] In this disclosure, a pressurizer may be installed on the housing 10, and a pressurization switch 42 electrically connected to the pressurizer is installed on the housing 10. The pressurization switch 42 is used to control the start and stop of the pressurizer. Here, the purpose of installing the pressurizer is to pressurize the coolant passing through the water pump 200 to simulate the pressure state of the coolant when the vehicle is in use, so as to restore the water pump 200 as much as possible to its operating state in the vehicle.

[0043] Optionally, such as Figures 1 to 3 As shown, a controller 40 is installed on the housing 10. The controller 40 is electrically connected to a pressure switch 42 and a heating switch 41. The controller 40 is also equipped with a pressure gauge 43 and a thermometer 44. The pressure gauge 43 displays the internal pressure of the housing 10, and the thermometer 44 displays the internal coolant temperature. The pressure gauge 43 and thermometer 44 allow for direct observation of the coolant temperature and pressure inside the housing 10, thus maximally replicating the actual operating conditions of the water pump 200 in the vehicle and ensuring the accuracy of the water pump 200 leakage test.

[0044] Optionally, such as Figures 1 to 3 As shown, multiple support rods 12 can be installed at the bottom of the housing 10. The housing 10 is supported by the support rods 12, which makes it easier to observe the leakage of the water pump 200 and prevents leakage of the housing 10 itself or water accumulation under the housing 10 from affecting the judgment of whether the water pump 200 is leaking.

[0045] Optionally, such as Figures 1 to 3 As shown, a drain outlet can be provided on the bottom wall of the housing 10, and a drain plug 13 can be detachably installed inside the drain outlet. The function of the drain plug 13 is to open and close the drain outlet, so as to facilitate the replacement of the coolant in the housing 10, and ensure that the coolant in the housing 10 can be replaced with the appropriate coolant in time when it needs to be replaced, so as to avoid the coolant itself affecting the test results of the water pump 200.

[0046] In this disclosure, the water pump leakage test device 100 includes a housing 10, a heater, a controller, a pressurizer, and a transmission structure 20. After the water pump 200 is installed, coolant is added to the housing 10 and covers the water pump 200. This coolant can be used for a long time. The heater heats the coolant to a specified temperature, and the pressurizer is turned on and set to a specified pressure. The drive component 23 (e.g., a motor) drives the water pump wheel to rotate. During the test, the water pump 200 can be kept in the working state it is in when used on the vehicle body, and the water pump is observed to see if it leaks.

[0047] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction, and this disclosure will not describe the various possible combinations separately.

[0049] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
