[0017] The automobile fuel pump assembly performance testing device is a device for testing the working state of the automobile fuel pump assembly, so as to judge whether the automobile fuel pump assembly is qualified.

[0018] The automobile fuel pump assembly performance detection device in the related art can only detect the working performance of the automobile fuel pump assembly in a static state, and cannot fully detect the working state of the fuel pump assembly under various road conditions.

[0019] Based on this, in order to improve the technical problem in the related art that the working status of the fuel pump assembly under various road conditions cannot be detected, the embodiment of the present application provides the following solution.

[0020] Please also read Figure 1 and Fig.12 The embodiment of the present application provides a vehicle fuel pump assembly performance detection device, which includes a mounting platform 10, a swinging portion 20, a simulated fuel tank 30 and a detection portion 40; wherein: The swinging portion 20 is disposed on the mounting platform 10 .

[0021] The simulated oil tank 30 is arranged on the swinging part 20, and the swinging part 20 is located between the mounting platform 10 and the simulated oil tank 30; the simulated oil tank 30 has a first space 300 and a first opening 301, the first space 300 is connected to the external space through the first opening 301, and the first opening 301 is facing away from the mounting platform 10; the simulated oil tank 30 includes a fixing part 31, and the fixing part 31 is telescopically arranged at the first opening 301.

[0022] The detection portion 40 is movably disposed on the swing portion 20 .

[0023] Among them, the simulated fuel tank 30 is used to fix the automobile fuel pump assembly in the first space 300 through the fixing part 31, the swinging part 20 is used to drive the simulated fuel tank 30 to swing so that the automobile fuel pump assembly in the first space 300 is in a swinging state, and is used to make the simulated fuel tank 30 still so that the automobile fuel pump assembly in the first space 300 is in a stationary state; the detection part 40 is used to move to the oil outlet of the fuel pump assembly to respectively detect the flow rate data of the oil outlet of the automobile fuel pump assembly in the swinging state and the stationary state.

[0024] It can be understood that the mounting platform 10 is a component for mounting the swinging part 20; for example, the mounting platform 10 can be a square mounting platform or a cylindrical mounting platform, etc. The swinging part 20 is a component for driving the simulated oil tank 30; for example, the swinging part 20 can be a device in which multiple crankshafts cooperate with multiple motors, one end of the crankshaft is connected to the power output end of the motor, and the other end of the crankshaft is connected to the bottom wall of the simulated oil tank 30, and the multiple motors drive the simulated oil tank 30 to swing through the multiple crankshafts; for another example, the swinging part 20 can also be multiple linear power devices (linear motors or cylinders, etc.), and the multiple linear power devices are connected to the simulated oil tank 30, and the simulated oil tank 30 is driven to swing through the reciprocating motion of the multiple linear power devices. The fixing member 31 is a component for fixing the fuel pump assembly in the simulated oil tank 30; for example, the fixing member 31 can be a closing plate of the simulated oil tank 30 or a closed shell of the simulated oil tank 30, etc. The detection unit 40 is a component for detecting the flow rate of the fuel pump assembly outlet; for example, the detection unit 40 can be a component that cooperates with a flow rate sensing device and a connecting structure, one end of the connecting structure is connected to the swinging portion 20, and the other end of the connecting structure is connected to the flow rate sensing device, and the flow rate sensing device is detachably arranged at the position of the fuel pump assembly outlet, thereby detecting the flow rate of the fuel pump assembly outlet; for another example, the detection unit 40 can be a flow rate sensing device, the flow rate sensing device is electrically connected to the swinging portion 20, and the flow rate sensing device is detachably arranged at the position of the fuel pump assembly outlet, thereby detecting the flow rate of the fuel pump assembly outlet.

[0025] As can be seen from the above, the automobile fuel pump assembly performance detection device provided in the embodiment of the present application is movably arranged at the first opening 301 by the fixing member 31, so that the fixing member 31 can move toward or away from the first opening 301, and thus the fixing member 31 can fix the fuel pump assemblies of different sizes in the simulated fuel tank 30. By providing a swinging part 20 between the simulated fuel tank 30 and the mounting platform 10, the swinging part 20 keeps the simulated fuel tank 30 in a stationary state, so that the state of the simulated fuel tank 30 and the fuel pump assembly therein is consistent with the state of the fuel pump assembly when the automobile is in a stationary state; the swinging part 20 can also drive the simulated fuel tank 30 to swing, so that the state of the simulated fuel tank 30 and the fuel pump assembly therein is consistent with the state when the automobile passes through a bumpy road section, and thus the detection unit 40 can detect the flow rate data of the fuel outlet of the automobile under different road conditions.

[0026] In some embodiments, please refer to Figures 1 to 12 , the detection unit 40 includes a conversion member 41, a stationary detection device 42 and a swing detection device 43; wherein: The conversion member 41 is movably disposed on the swinging portion 20 , and has an input port 410 , a stationary output port 411 connected to the input port 410 , and a swinging output port 412 . The input port 410 is connected to the oil outlet of the automobile fuel pump assembly.

[0027] The stationary detection device 42 is connected to the stationary output port 411 and is used to detect the flow rate of the fuel outlet when the automobile fuel pump assembly is in a stationary state.

[0028] The swing detection device 43 is connected to the swing output port 412 to detect the flow rate of the fuel outlet when the automobile fuel pump assembly is in a swing state.

[0029] It can be understood that the conversion member 41 is a component used to convert the fuel pump outlet into two output ports; for example, the conversion member 41 can be a block having an input port 410, a static output port 411 and a swinging output port 412, or a shell having an input port 410, a static output port 411 and a swinging output port 412. The stationary detection device 42 is a device used to guide the fuel from the outlet when the fuel pump assembly is stationary; for example, the stationary detection device 42 can be an infusion hose or an infusion guide, etc. The swing detection device 43 is a device used to guide the fuel from the outlet when the fuel pump assembly is swinging; for example, the swing detection device 43 can be an infusion hose or an infusion guide, etc.

[0030] In this way, by providing an input port 410, a stationary output port 411 and a swinging output port 412 on the conversion member 41, and the input port 410, the stationary output port 411 and the swinging output port 412 are connected, the input port 410 is connected to the oil outlet of the fuel pump assembly, the stationary output port 411 is connected to the stationary detection device 42, and the swinging output port 412 is connected to the swinging detection device 43, so that the liquid flowing out of the oil outlet can flow out through the stationary detection device 42 or the swinging detection device 43, and then the detection unit 40 can respectively detect the flow rate of the oil outlet of the fuel pump assembly; compared with directly installing the flow rate sensing device at the oil outlet of the fuel pump assembly, this scheme can simultaneously detect the flow rate of the oil outlet when the fuel pump assembly is in a stationary state and a swinging state in one detection process.

[0033] The first transverse spring 23 is located in the adjustment space 101, and one end of the first transverse spring 23 is connected to the inner wall of the adjustment space 101, and the other end of the first transverse spring 23 is connected to the side wall of the connecting member 21; the expansion and contraction directions of each first transverse spring 23 are parallel, and the first transverse spring 23 is used to drive the simulated oil tank 30 to swing along the expansion and contraction direction of the first transverse spring 23 under the action of force.

[0034] The second transverse spring 24 is located in the adjustment space 101, and the two ends of at least one second transverse spring 24 are respectively connected to a side wall of the connecting member 21 and one of the sliding members 22, and the two ends of at least one second transverse spring 24 are respectively connected to the other side wall of the connecting member 21 and the other sliding member 22, and the expansion and contraction directions of each second transverse spring 24 are parallel; the second transverse spring 24 is used to drive the simulated oil tank 30 to swing along the expansion and contraction direction of the second transverse spring 24 under the action of force, and the expansion and contraction direction of the second transverse spring 24 forms an angle with the expansion and contraction direction of the first transverse spring 23.

[0035] One end of the longitudinal spring 25 is connected to the side of the simulated oil tank 30 facing the mounting platform 10, and the other end of the longitudinal spring 25 is connected to the side of the connecting piece 21 facing the simulated oil tank 30; the longitudinal spring 25 is used to drive the simulated oil tank 30 to swing along the expansion and contraction direction of the longitudinal spring 25 under the action of force, and the expansion and contraction direction of the longitudinal spring 25 forms an angle with the expansion and contraction direction of the second transverse spring 24 and the expansion and contraction direction of the first transverse spring 23 respectively.

The second transverse spring 24 is a component used to drive the simulated oil tank 30 to swing along the expansion and contraction direction of the second transverse spring 24 through the connecting member 21. The longitudinal spring 25 is a component used to drive the simulated oil tank 30 to swing along the expansion and contraction direction of the longitudinal spring 25.

[0037] In this way, the side wall of the connecting member 21 is connected to the inner side wall of the adjustment space 101 through the first transverse spring 23 and the second transverse spring 24, so that the first transverse spring 23 and the second transverse spring 24 drive the connecting member 21 to swing along the expansion and contraction direction of the first transverse spring 23 or the expansion and contraction direction of the second transverse spring 24, thereby driving the simulated oil tank 30 to swing along the expansion and contraction direction of the first transverse spring 23 or the expansion and contraction direction of the second transverse spring 24; and a longitudinal spring 25 is arranged between the connecting member 21 and the simulated oil tank 30, so that the simulated oil tank 30 can swing along the expansion and contraction direction of the longitudinal spring 25. Compared with the scheme of matching multiple crankshafts with multiple linear power devices (linear motors or hydraulic cylinders, etc.), the above scheme can simplify the device and reduce the production cost; and the springs usually used in the shock absorbing device of the car, the above scheme can make the simulated oil tank 30 simulate the real situation of the car tank well.

[0038] Optionally, see Figures 1 to 12 , a longitudinal adjustment hole 210 is provided on the side of the connecting member 21 facing the simulated oil tank 30; a first adjustment through hole 103 and a first transverse adjustment hole 104 are respectively provided on the inner side wall of the adjustment space 101; a second adjustment through hole 220 is provided on the side wall of one of the sliding members 22 facing the second transverse spring 24, and a second transverse adjustment hole 221 is provided on the side wall of the other sliding member 22 facing the second transverse spring 24; the swinging part 20 further includes a longitudinal adjustment structure 26, a first transverse adjustment structure 27 and a second transverse adjustment structure 28; wherein: One end of the longitudinal adjustment structure 26 is connected to a side of the simulated oil tank 30 facing the mounting platform 10 , and the other end of the longitudinal adjustment structure 26 is movably disposed in the longitudinal adjustment hole 210 .

[0039] The first lateral adjustment structure 27 includes a first adjustment member 271 and a first fixing member 272.

[0040] The second lateral adjustment structure 28 includes a second adjustment member 281 and a second fixing member 282, one end of the second adjustment member 281 and the second fixing member 282 are connected to the side wall of the connecting member 21, the other end of the second adjustment member 281 is movably inserted into the second adjustment through hole 220, and the other end of the second fixing member 282 is movably disposed in the second lateral adjustment hole 221.

[0041] It can be understood that the longitudinal adjustment structure 26 is a structure used to keep the longitudinal spring 25 in a compressed or stretched state; for example, the longitudinal adjustment structure 26 can be a structure composed of a longitudinal fixing rod and a longitudinal locking device, and the longitudinal fixing rod is adjusted to be located in the longitudinal adjustment hole 210, and the longitudinal fixing rod is fixed by the longitudinal locking device to keep the longitudinal spring 25 in a compressed or stretched state; for another example, the longitudinal adjustment structure 26 can also be a structure composed of a longitudinal adjustment rod with an expansion space and an expansion airbag, and the expansion airbag is arranged in the expansion space, and the longitudinal adjustment rod is adjusted to be located in the longitudinal adjustment hole 210, and the expansion airbag is inflated to fix the longitudinal adjustment rod in the longitudinal adjustment hole 210, thereby keeping the longitudinal spring 25 in a compressed or stretched state.

[0042] The first transverse adjustment structure 27 is a structure for keeping the first transverse spring 23 in a compressed or stretched state; for example, the first transverse adjustment structure 27 may be a structure composed of a first transverse fixing rod and a first transverse locking device, by adjusting the position of the first transverse fixing rod in the first transverse adjustment hole 104, and fixing the first transverse fixing rod by the first transverse locking device, so that the first transverse spring 23 is kept in a compressed or stretched state; for another example, the first transverse adjustment structure 27 may also be a structure composed of a first transverse adjustment rod with an expansion space and an expansion airbag, the expansion airbag is arranged in the expansion space, by adjusting the position of the first transverse adjustment rod in the first transverse adjustment hole 104, and inflating the expansion airbag, so that the first transverse adjustment rod is fixed in the first transverse adjustment hole 104, thereby keeping the first transverse spring 23 in a compressed or stretched state. The first adjustment member 271 is a member for adjusting the extension or extension degree of the first transverse spring 23; for example, the first adjustment member 271 may be a rectangular rod or a cylindrical shell, etc. The first fixing member 272 is a component used to keep the first transverse spring 23 in a telescopic or stretched state; for example, the first fixing member 272 may be a rectangular rod or a cylindrical shell, etc.

[0043] The second transverse adjustment structure 28 is a structure for keeping the second transverse spring 24 in a compressed or stretched state; for example, the second transverse adjustment structure 28 may be a structure composed of a second transverse fixing rod and a second transverse locking device, by adjusting the position of the second transverse fixing rod in the second transverse adjustment hole 221, and fixing the second transverse fixing rod by the second transverse locking device, so that the second transverse spring 24 is kept in a compressed or stretched state; for another example, the second transverse adjustment structure 28 may also be a structure composed of a second transverse adjustment rod with an expansion space and an expansion airbag, the expansion airbag is arranged in the expansion space, by adjusting the position of the second transverse adjustment rod in the second transverse adjustment hole 221, and inflating the expansion airbag, so that the second transverse adjustment rod is fixed in the second transverse adjustment hole 221, thereby keeping the second transverse spring 24 in a compressed or stretched state.

The longitudinal adjustment structure 26 is also used to move freely in the longitudinal adjustment hole 210 to release the elastic potential energy of the longitudinal spring 25, thereby driving the simulated oil tank 30 to swing along the extension direction of the longitudinal spring 25; the first transverse adjustment structure 27 is also used to move freely in the first transverse adjustment hole 104 to release the elastic potential energy of the first transverse spring 23, thereby driving the simulated oil tank 30 to swing along the extension direction of the first transverse spring 23; the second transverse adjustment structure 28 is also used to move freely in the second transverse adjustment hole 221 to release the elastic potential energy of the second transverse spring 24, thereby driving the simulated oil tank 30 to swing along the extension direction of the second transverse spring 24. Compared with the direction of directly using multiple linear motors, the above scheme can reduce costs; and since most vehicles use springs for shock absorption during the formation process, the above scheme can be closer to the actual situation.

[0045] For example, see Figures 1 to 12 A longitudinal locking hole 211 is provided on the inner side wall of the longitudinal adjustment hole 210, and the longitudinal adjustment structure 26 includes a longitudinal fixing member 261 and a longitudinal locking structure 262; wherein: One end of the longitudinal fixing member 261 is connected to the side of the simulated oil tank 30 facing the mounting platform 10, and the other end of the longitudinal fixing member 261 is movably arranged in the longitudinal adjustment hole 210; and a plurality of longitudinal stop openings 2610 are opened on the outer wall of the longitudinal fixing member 261, and the arrangement direction of the plurality of longitudinal stop openings 2610 is parallel to the extension and contraction direction of the longitudinal spring 25.

[0059] Among them, the longitudinal elastic member 2623 is used to push the longitudinal stopping member 2622 into the longitudinal stopping opening 2610, so that the longitudinal fixing member 261 is fixed in the longitudinal adjustment hole 210, and the longitudinal spring 25 is in a compressed or stretched state; the longitudinal hydraulic member 2621 is used to push the longitudinal stopping member 2622 out of the longitudinal stopping opening 2610, so that the longitudinal fixing member 261 can move freely in the longitudinal adjustment hole 210, and then the longitudinal spring 25 drives the simulated oil tank 30 to swing along the extension and contraction direction of the longitudinal spring 25.

[0060] It can be understood that the longitudinal hydraulic component 2621 is a component used to push the longitudinal stopper 2622 to move toward the inner bottom wall of the longitudinal stopper hole 211; the longitudinal hydraulic component 2621 can be a square hydraulic cylinder or a cylindrical hydraulic cylinder.

[0068] In some embodiments, see Figures 1 to 8 The side wall of the second transverse locking hole 2210 is provided with a second transverse hydraulic space 2211, and the second transverse locking structure 283 includes a second transverse hydraulic component 2831, a second transverse locking component 2832 and a second transverse elastic component 2833; wherein: The second transverse hydraulic component 2831 is disposed in the second transverse hydraulic space 2211 .

[0069] The second transverse retaining member 2832 is movably disposed in the second transverse retaining hole 2210 , and a portion of the second transverse retaining member 2832 is located in the second transverse hydraulic member 2831 .

[0070] The second transverse elastic member 2833 is disposed in the second transverse locking hole 2210 , one end of the second transverse elastic member 2833 is connected to the second transverse locking member 2832 , and the other end of the second transverse elastic member 2833 is connected to the inner bottom wall of the second transverse locking hole 2210 .

[0071] Among them, the second transverse elastic member 2833 is used to push the second transverse stopping member 2832 into the second transverse stopping port 2820, so that the second fixing member 282 is fixed in the second transverse adjustment hole 221, and the second transverse spring 24 is in a compressed or stretched state; the second transverse hydraulic member 2831 is used to push the second transverse stopping member 2832 out of the second transverse stopping port 2820, so that the second fixing member 282 can move freely in the second transverse adjustment hole 221, and then the second transverse spring 24 drives the simulated oil tank 30 to swing along the extension and contraction direction of the second transverse spring 24.

[0072] It can be understood that the second transverse hydraulic member 2831 is a member used to push the second transverse stop member 2832 to move toward the inner bottom wall of the second transverse stop hole 2210; the second transverse hydraulic member 2831 can be a square hydraulic cylinder or a cylindrical hydraulic cylinder. The second transverse stop member 2832 is a member used to enter the second transverse stop opening 2820 to fix the second fixing member 282 in the second transverse adjustment hole 221, or to move out of the second transverse stop opening 2820 to freely move the second fixing member 282 in the second transverse adjustment hole 221; for example, the second transverse stop member 2832 can be a square rod or a cylindrical shell. The second transverse elastic member 2833 is a member used to push the second transverse stop member 2832 to move away from the inner bottom wall of the second transverse stop hole 2210; for example, the second transverse elastic member 2833 can be a spring or an elastic sheet.

[0073] In this configuration, the second transverse stopper 2832 is pushed into the second transverse stopper opening 2820 by the second transverse elastic member 2833, so that the second fixing member 282 can be fixed in the second transverse adjustment hole 221; the second transverse stopper 2832 is pushed out of the second transverse stopper opening 2820 by the second transverse hydraulic member 2831, so that the second fixing member 282 can freely move in the second transverse adjustment hole 221. Compared with the scheme of directly controlling by the second transverse elastic member 2833, the above scheme can more conveniently control the second transverse stopper 2832 to enter or move out of the second transverse stopper opening 2820 according to the state of the fuel pump assembly.

[0074] In some embodiments, see Figures 4 to 14The longitudinal hydraulic component 2621 is provided with a longitudinal infusion port 2624, the first transverse hydraulic component 2731 is provided with a first transverse infusion port 2734, the second transverse hydraulic component 2831 is provided with a second transverse infusion port 2834, and the stationary detection device 42 includes a branch component 421, a first infusion tube 422, a second infusion tube 423, a third infusion tube 424, a fourth infusion tube 425 and a first flow rate sensor 426; wherein: The branch member 421 has a stationary input port, a first output port connected to the stationary input port, a second output port, and a third output port.

[0075] One end of the first infusion tube 422 is connected to the static input port, and the other end of the first infusion tube 422 is connected to the static output port 411 .

[0076] One end of the second infusion tube 423 is connected to the first output port, and the other end of the second infusion tube 423 is connected to the longitudinal infusion port 2624 .

[0077] One end of the third infusion tube 424 is connected to the second output port, and the other end of the second infusion tube 423 is connected to the first horizontal infusion port 2734 .

[0078] One end of the fourth infusion tube 425 is connected to the third output port, and the other end of the fourth infusion tube 425 is connected to the second horizontal infusion port 2834; and The first flow rate sensor 426 is disposed in the first infusion tube 422 .

[0079] It can be understood that the branching member 421 is a member used to evenly distribute the fuel in the first liquid delivery pipe 422 to the second liquid delivery pipe 423, the third liquid delivery pipe 424 and the fourth liquid delivery pipe 425; for example, the branching member 421 can be a four-way joint or a distribution header, etc. The first flow velocity sensor 426 is a device used to detect the flow velocity of the liquid in the first liquid delivery pipe 422; for example, the first flow velocity sensor 426 can be a mechanical flow velocity sensor or an electromagnetic flow velocity sensor, etc.

[0080] In this way, by setting the branch member 421, the fuel is evenly input into the longitudinal hydraulic component 2621, the first transverse hydraulic component 2731 and the second transverse hydraulic component 2831 through the second infusion pipe 423, the third infusion pipe 424 and the fourth infusion pipe 425, so that the longitudinal hydraulic component 2621, the first transverse hydraulic component 2731 and the second transverse hydraulic component 2831 can be controlled simultaneously, thereby making the simulated fuel tank 30 swing in multiple directions at the same time, so that the simulated fuel tank 30 can swing in multiple directions. And in this process, the fuel pump assembly is in a stationary state, so that the first flow rate sensor 426 detects the flow rate of the fuel outlet when the fuel pump assembly is in a stationary state. Compared with the solution of controlling the longitudinal hydraulic component 2621, the first transverse hydraulic component 2731 and the second transverse hydraulic component 2831 simultaneously through the circuit, the above solution can simplify the device and reduce the production cost. At the connection between the first infusion pipe 422 and the branch piece 421, the fuel flow rate is unstable. By setting the first flow rate sensor 426 in the first infusion pipe 422, the fuel flow rate detected by the first flow rate sensor 426 is closer to the actual flow rate of the fuel pump assembly outlet.

[0081] In some embodiments, see Figures 1 to 4 The swing detection device 43 includes a fifth infusion tube 431 and a second flow rate sensor 432; wherein: One end of the fifth infusion tube 431 is connected to the static output port 411 . The second flow rate sensor 432 is disposed in the fifth infusion tube 431 .

[0082] It can be understood that the second flow rate sensor 432 is a device for detecting the flow rate of the liquid in the fifth infusion tube 431; for example, the first flow rate sensor 426 can be a mechanical flow rate sensor or an electromagnetic flow rate sensor, etc.

[0083] With such arrangement, when the fuel pump assembly swings, the fuel is introduced into the collection container by arranging the fifth liquid delivery pipe 431, thereby avoiding fuel waste. At the connection between the fifth liquid delivery pipe 431 and the stationary output port 411, the fuel flow rate is unstable. By arranging the second flow rate sensor 432 in the fifth liquid delivery pipe 431, the fuel flow rate detected by the second flow rate sensor 432 is closer to the actual flow rate of the fuel pump assembly outlet.

[0084] In some embodiments, see Figure 5 The first infusion tube 422, the second infusion tube 423, the third infusion tube 424, the fourth infusion tube 425 and the fifth infusion tube 431 are detachably arranged on the automobile fuel pump assembly performance detection device.

[0085] In this way, by setting the first infusion tube 422, the second infusion tube 423, the third infusion tube 424, the fourth infusion tube 425 and the fifth infusion tube 431 to be detachable, the first infusion tube 422, the second infusion tube 423, the third infusion tube 424, the fourth infusion tube 425 and the fifth infusion tube 431 can be replaced after being damaged.

[0086] In some embodiments, see Figure 1 , Fig.13 and Fig.14 , the conversion element 41 includes a first valve 413, a second valve 414, a vibration sensor 415 and a control unit 416; wherein: The first valve 413 is disposed at the swing output port 412 , and the first valve 413 is used to open or close the swing output port 412 .

[0087] The second valve 414 is disposed at the stationary output port 411 , and the second valve 414 is used to open or close the stationary output port 411 .

[0088] The vibration sensor 415 is disposed on the simulated oil tank 30 .

[0089] The control unit 416 is disposed on the simulated oil tank 30 . An input end of the control unit 416 is electrically connected to the vibration sensor 415 , and an output end of the control unit 416 is electrically connected to the first valve 413 and the second valve 414 .

[0090] Among them, the vibration sensor 415 is used to sense that the simulated oil tank 30 is in a stationary state, and sends the stationary state of the simulated oil tank 30 to the control unit 416, so that the control unit 416 opens the second valve 414 and closes the first valve 413; the vibration sensor 415 is also used to sense that the simulated oil tank 30 is in a swinging state, and sends the swinging state of the simulated oil tank 30 to the control unit 416, so that the control unit 416 opens the first valve 413 and closes the second valve 414.

[0091] It can be understood that the first valve 413 is a component for opening or closing the swing output port 412; the first valve 413 can be a plate or an inflatable airbag, etc. The second valve 414 is a component for opening or closing the stationary output port 411; the second valve 414 can be a plate or an inflatable airbag, etc. The vibration sensor 415 is a device for sensing whether the simulated oil tank 30 is swinging. The control unit 416 is a device for controlling the opening or closing of the first valve 413 and the second valve 414 according to the situation sensed by the vibration sensor 415; the control unit 416 can be a single chip microcomputer or a PLC (programmable logic controller), etc.

[0092] In this configuration, the vibration sensor 415 is used to sense the state of the simulated fuel tank 30 being stationary, and the control unit 416 controls the closing of the first valve 413 and the opening of the second valve 414, so that the first flow rate sensor 426 can detect the flow rate of the fuel pump assembly outlet when the fuel pump assembly is in a stationary state; the vibration sensor 415 is also used to sense the state of the simulated fuel tank 30 swinging, and the control unit 416 controls the opening of the first valve 413 and the closing of the second valve 414, so that the second flow rate sensor 432 can detect the flow rate of the fuel pump assembly outlet when the fuel pump assembly is in a swinging state. The solution of setting multiple one-way valves at the stationary input port and the stationary output port 411 will affect the flow rate of the fuel pump assembly outlet when the fuel pump assembly is in a swinging state, thereby causing the flow rate detected by the second flow rate sensor 432 to be different from the actual flow rate.

[0093] In some embodiments, the simulated oil tank 30 further includes a height adjustment device 50 , which is disposed in the first space 300 , and one end of the height adjustment device 50 is connected to the fixing member 31 so that the height adjustment device 50 can adjust the height of the fixing member 31 .

[0094] It can be understood that the height adjustment device 50 is a device for adjusting the height of the fixing member 31; for example, the height adjustment device 50 can be a device in which a rotating motor and a threaded rod 52 cooperate, the power output end of the rotating motor is connected to one end of the threaded rod 52, and the threaded rod 52 is connected to the fixing member 31 through threaded cooperation, and the threaded rod 52 is driven to rotate by the rotating motor, so that the threaded rod 52 drives the fixing member 31 to move, thereby changing the height of the fixing member 31.

[0095] In this way, the height of the fixing member 31 is controlled by the height adjustment device 50, so that the fixing member 31 can fix fuel pump assemblies of different heights.

[0096] In some embodiments, see Figure 1 and Fig. 9 , an internal threaded through hole is formed at one end of the fixing member 31, a sliding groove 302 is formed on the inner wall of the simulated oil tank 30, and the length direction of the sliding groove 302 is consistent with the depth direction of the simulated oil tank 30; a part of the fixing member 31 is movably arranged in the sliding groove 302, and the height adjustment device 50 includes a power device 51 and a threaded rod 52; wherein: The power device 51 is arranged at one side of the simulated oil tank 30. One end of the threaded rod 52 is connected to the power output end of the power device 51, and the threaded rod 52 is threadedly connected in the internal thread through hole.

[0097] It can be understood that the power device 51 is a device for driving the threaded rod 52 to rotate; the power device 51 can also be a motor or a small fuel engine, etc. The threaded rod 52 is a component for pushing the fixing member 31 to move.
