Description

Technical Field

[0001] This utility model belongs to the technical field of generator testing devices, and more specifically, relates to a generator oil separator ring target testing device. Background Technology

[0002] The stator assembly and rotor assembly are key components of the generator. During their operation, they generate a large amount of heat due to the action of current and electromagnetic effects. To prevent the stator assembly from overheating and causing coil burnout, and the rotor assembly from overheating and causing demagnetization, some generators use an oil distribution ring in the generator housing design. By spraying oil through the oil distribution ring, the stator and rotor are forced to cool. The use of this structure can effectively reduce the temperature of the stator and rotor, improve generator performance, and enhance generator reliability.

[0003] However, due to improper material selection, inadequate fit with the housing, and unreasonable design of the oil orifice diameters, the oil distributor ring may leak excessively during operation, resulting in insufficient oil spraying onto the stator and rotor for optimal cooling. To eliminate this issue and supplement the limitations of CAE analysis, a generator oil distributor ring test is necessary to verify the oil jet trajectory and the oil injection volume of each orifice. Solving the problems of poor injection trajectory and excessive leakage requires adjustments to the material, thickness, and fit dimensions of the oil distributor ring. For cases with significant differences in oil injection volume among the orifices, the orifice diameters need to be adjusted.

[0004] Therefore, a generator oil separator ring target test device is needed to conduct target tests on the oil separator ring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a generator oil distributor ring target test device, which solves the existing problem of needing to verify the oil jet trajectory and the amount of oil injected into each hole.

[0006] To achieve the above objectives, this utility model provides a generator oil separator ring target test device, comprising: The generator housing is open-type and has at least one mounting position for detachable connection of the oil distribution ring. The generator housing also has a main oil passage for connection with the oil distribution ring, and the main oil passage is connected to an oil delivery pipe and an oil monitoring module.

[0007] Optionally, the oil monitoring module is a pressure gauge.

[0008] Optionally, the reading end of the pressure gauge is located outside the generator housing.

[0009] Optionally, the oil distribution ring includes an oil ring body and multiple oil holes, wherein the oil ring body is provided with an oil ring channel connecting the main oil channel and the oil holes.

[0010] Optionally, one end of the oil pipeline is connected to the main oil channel via a connecting device, and the other end of the oil pipeline is connected to an oil pump for testing equipment.

[0011] Optionally, it also includes a collector for collecting the oil output from each oil hole.

[0012] Optionally, the connection device is exposed outside the generator housing.

[0013] Optionally, the oil pump of the test equipment can output oil at different pressures.

[0014] Optionally, the mounting position is provided with a connection port and a sealing element that is detachably connected to the connection port.

[0015] Optionally, the oil pipeline is equipped with a pressure relief valve.

[0016] This utility model provides a generator oil separator ring target test device, the advantages of which are: This generator oil distributor ring target testing device utilizes an open design on the generator casing to allow for direct visual observation of the oil spray cooling effect during testing, confirming the oil output from each oil orifice. The open structure also allows for the collection of oil sprayed from the oil distributor ring, either manually or via a collector, further confirming the oil output. An oil delivery pipe, in conjunction with an oil monitoring module, confirms the oil output effect under different oil pressures, monitoring the oil output and spray position at varying pressures, facilitating adjustments to the oil distributor ring's parameters. Furthermore, it delivers cooling oil directly to the main oil passage, eliminating the need for the generator's oil delivery pipeline.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0022] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0023] like Figure 1-2 As shown, a generator oil separator ring target test device includes: The generator housing 1 is open-type and has at least one mounting position for the detachable connection of the oil distributor ring 3. The generator housing 1 also has a main oil passage 2 for connecting to the oil distributor ring 3, which is connected to an oil supply pipe 7 and an oil monitoring module 5. Specifically, the open design of the generator housing 1 allows for direct visual observation of the oil injection cooling effect during testing, confirming the oil output from each oil hole 33. The open structure also allows for the collection of oil sprayed from the oil distributor ring 3 using a collector or manually, thus confirming the oil output. During the testing of the oil distributor ring 3, after it is assembled into the generator housing 1, the safety of its assembly and its position within the housing are first tested before the oil injection cooling effect is tested. The oil supply pipe 7, in conjunction with the oil monitoring module 5, confirms the oil output effect under different oil pressures, thereby monitoring the oil output and injection position under different oil pressures, facilitating adjustments to various parameters of the oil distributor ring 3. It directly supplies cooling oil to the main oil channel 2, without having to go through the generator's oil supply pipeline 7.

[0024] Furthermore, the oil distributor ring 3 can be selected to spray oil outwards, inwards, laterally, or in multiple directions as needed. The parameters of the oil distributor ring 3 include the parameters of the oil hole 33 and the parameters of the oil distributor ring body 31, such as material and specifications. The generator housing 1 is modified from an actual pre-made housing. The stator and rotor are detachably connected to the generator housing 1, and whether or not they are installed depends on the purpose of the test.

[0025] In this embodiment, the oil monitoring module 5 is a pressure gauge.

[0026] Specifically, the oil pressure is confirmed using a pressure gauge.

[0027] In this embodiment, the reading end of the pressure gauge is located outside the generator housing 1.

[0028] Specifically, the pressure gauge's reading is located outside the generator housing 1 for easy observation, while avoiding encroachment on the internal space of the generator housing 1.

[0029] In this embodiment, the oil distribution ring 3 includes an oil ring body 31 and a plurality of oil holes 33. The oil ring body 31 is provided with an oil ring channel 32 that connects the main oil channel 2 and the oil holes 33.

[0030] Specifically, because the spray cooling positions of each oil hole 33 are different, the oil distribution ring 3 test also needs to test the oil output and spray area of ​​each oil hole 33. The oil ring oil channel 32 delivers cooling oil to each oil hole 33, and the effect of spraying oil is ensured by adjusting the orifice diameter, depth and orientation of each oil hole 33.

[0031] In this embodiment, one end of the oil pipeline 7 is connected to the main oil channel 2 via the connecting device 4, and the other end of the oil pipeline 7 is connected to the test equipment oil pump 6.

[0032] Specifically, the test equipment oil pump 6 delivers cooling oil directly to the main oil passage 2 through the oil supply pipe 7 and the connecting device 4, without having to go through the generator's oil supply pipeline. The test equipment oil pump 6 is used to simulate different oil pressures at different speeds.

[0033] Furthermore, the complete generator housing 1 is connected to the vehicle cooling system, and the connecting device 4 replaces the oil supply of the vehicle cooling system and can be connected at the interface between the generator housing 1 and the vehicle cooling system.

[0034] In this embodiment, a collector is also included, which is used to collect the oil output from each oil hole 33.

[0035] Specifically, the collector is used in conjunction with manual labor, such as a measuring cup.

[0036] In this embodiment, the connecting device 4 is exposed outside the generator housing 1.

[0037] Specifically, to prevent the connecting device 4 from encroaching on the internal space of the generator housing or obstructing the view.

[0038] In this embodiment, the oil pump 6 of the test equipment can output oil at different pressures.

[0039] In this embodiment, the mounting position is provided with a connection port and a sealing element that can be detachably connected to the connection port.

[0040] Specifically, when there are unused installation positions, they can be sealed with sealing components.

[0041] In this embodiment, the oil pipeline 7 is equipped with a pressure relief valve.

[0042] Specifically, during the test, the oil distribution ring 3 did not produce good oil output, and the pressure relief valve was used to ensure safety.

[0043] In this embodiment, when using the generator oil distribution ring 3 target test device, taking the test oil ring as an example of its use in a complete vehicle: Install the two oil distribution rings 3 to their corresponding positions on the generator housing 1, and test whether the generator housing 1 can be assembled stably and safely. After successful assembly, connect the oil pump 6 of the test equipment to test the oil output status of the oil distribution rings 3 under different oil pressures. By continuously adjusting the various parameters of the oil distribution rings 3, the optimal parameter data of the oil distribution rings 3 are finally selected.

[0044] When testing the oil output effect, the stator and rotor need to be installed; when collecting the oil output, the stator and rotor can be disassembled.

[0045] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
