The main metering hole 200 of the carburetor is placed on the measuring base 2, and its notch 2001 faces the pressure rod assembly 13. The pressure rod assembly 13 can be pressed toward the main metering hole 200 of the carburetor under the action of the measuring drive unit 11, so that the measuring mechanism 1 is connected with the main metering hole 200 of the carburetor, and the test oil in the external oil tank 300 can pass through the measuring pipe 14, the measuring head body 12, the pressure rod assembly 13, the main metering hole 200 of the carburetor and the measuring base 2, and the flow sensor 15 can measure the maximum flow of the main metering hole 200 of the carburetor in the oil inlet direction a.
[0046] According to some embodiments of the present application, optionally, Figure 1 and Figure 4 As shown, the pressure rod assembly 13 includes a pressure rod 131, an elastic member 132 and a pressure rod sleeve 133.

[0047] The measuring head body 12 has an installation cavity, and the pressure rod 131 and the elastic member 132 are installed in the installation cavity. The pressure rod 131 has a pressure rod through hole, and the pressure rod through hole is connected to the notch 2001 of the main metering hole 200 of the carburetor. The elastic member 132 is elastic and can elastically shrink when subjected to pressure, and can restore the initial shape when the pressure disappears. The elastic member 132 can be made of metal elastic materials such as metal springs, or can be made of non-metal elastic materials such as rubber and silicone.
[0048] In this way, the pressure rod 131 moves along the vertical direction Y under the action of the measuring drive unit 11 , and communicates with the notch 2001 of the main metering hole 200 of the carburetor under the action of the elastic member 132 .

[0050] Thus, the nut 134 has a simple structure, and is convenient for installing the pressure rod sleeve 133 and the measuring head body 12 .
[0051] According to some embodiments of the present application, optionally, Figure 1 and Figure 4 As shown, the measuring mechanism 1 further includes a first sealing member 16 , which is disposed between the top of the pressure rod sleeve 133 and the measuring head body 12 .
[0052] The first sealing member 16 may be a sealing ring or a sealing gasket or the like.

[0054] According to some embodiments of the present application, optionally, Figure 1 and Figure 4 As shown, the measuring mechanism 1 further includes a second sealing member 17 , which is disposed at the bottom of the pressure rod sleeve 133 , and is used to contact the top of the measuring base 2 .
[0055] The second sealing member 17 may be a sealing ring or a sealing gasket and the like.
[0056] In this way, the second sealing member 17 further improves the accuracy of measurement and avoids oil leakage between the pressure rod sleeve 133 and the measuring base 2 when the pressure rod sleeve 133 contacts the measuring base 2 .
[0057] According to some embodiments of the present application, optionally, Figure 1 and Figure 3 As shown, the measuring mechanism 1 further includes a third sealing member 18 , which is disposed between the bottom of the main metering hole 200 of the carburetor and the measuring base 2 .
[0058] The third sealing member 18 may be a sealing ring or a sealing gasket and the like.
[0059] In this way, the third sealing member 18 further improves the accuracy of the measurement and avoids oil leakage between the main metering hole 200 of the carburetor and the measuring base 2 .
[0060] According to some embodiments of the present application, optionally, Figure 1 and Figure 5 As shown, the measuring mechanism 1 further includes a solenoid valve switch 19 , which is disposed on the measuring pipe 14 .
[0061] In this way, the measuring pipeline 14 can be opened or closed by the solenoid valve switch 19, thereby controlling whether the testing oil in the external oil tank 300 is to be tested.
[0062] According to some embodiments of the present application, optionally, Figure 1 and Figure 5 As shown, the carburetor main orifice flow measurement device 100 further includes a collecting tank 3 , which is disposed below the measuring base 2 and is used to collect the test oil flowing out of the measuring base 2 .
[0063] In this way, the tested test oil can be recycled through the collection tank 3, avoiding waste of the test oil and pollution of the environment.
[0064] The working principle of the carburetor main orifice flow measurement device 100 is as follows: before use, the solenoid valve switch 19 is in a closed state, and the measuring pipe 14 is not conducting. At the same time, the cylinder is not working and is located above the notch 2001 of the carburetor main orifice 200. The carburetor main orifice 200 is placed in the measuring base 2, and the notch 2001 of the carburetor main orifice 200 is aligned with the pressure rod 131. When in use, the cylinder is controlled to work, and the piston rod of the cylinder drives the measuring head body 12 to move along the vertical direction Y as a whole. During this process, the top of the pressure rod sleeve 133 is sealed with the measuring head body 12 by the first sealing member 16. The bottom of the pressure rod sleeve 133 is in contact with the top of the measuring base 2 and is sealed by the third sealing member 18. Under the action of the elastic member 132, the pressure rod 131 is pressed toward the top of the notch 2001 of the main metering hole 200 of the carburetor and sealed by the second sealing member 17, so that the pressure rod 131 is connected with the notch 2001 of the main metering hole 200 of the carburetor. After the downward stroke of the cylinder is reached, the solenoid valve switch 19 is turned on, and the test oil in the external oil tank 300 continues to enter the main metering hole 200 of the carburetor in the oil inlet direction a through the measuring pipe 14, the measuring head body 12 and the pressure rod 131 for testing, and the test oil is collected by the collection tank 3. In this process, the test oil is affected by the diameter of the notch 2001 of the main metering hole 200 of the carburetor and will be maintained at a flow rate. Therefore, the flow sensor 15 can measure the maximum flow rate of the main metering hole 200 of the carburetor in the oil inlet direction a. Finally, after the measurement is completed, the solenoid valve switch 19 is turned off, and the cylinder is controlled to return to its original state, and the main metering hole 200 of the carburetor is taken out from the measuring base 2.
