Description

Technical Field

[0001] This invention relates to the field of fluid flow technology, and more specifically to a method for detecting the flow rate of an oil supply nozzle. Background Technology

[0002] Fuel injectors (also known as fuel liners) are a crucial component of the engine's fuel supply system. Over time, carbon buildup can occur on these injectors, affecting normal fuel delivery. Many repair shops rely on visual inspection to determine the presence of carbon buildup on fuel injectors, lacking scientific testing methods and frequently leading to misdiagnosis. Many users have reported that during engine maintenance, repair shops diagnosed carbon buildup on the fuel injectors, but replacing them did not resolve the engine problem.

[0003] Based on this, it is necessary to design a scientific method for detecting the flow rate of the fuel nozzle. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for detecting the flow rate of a fuel injector, which can scientifically detect the flow rate of the fuel injector and determine whether carbon deposits have occurred in the fuel injector.

[0005] This invention provides the following technical solution:

[0006] A method for detecting the flow rate of an oil supply nozzle, comprising using a flow detection device to detect the flow rate of oil passing through the oil supply nozzle;

[0007] The flow detection device includes two main flow pipes (1) and a pipe connector (2), and the two main flow pipes (1) are sealed together by the pipe connector (2);

[0008] The middle part of the pipe connector (2) is fixedly connected with two or more guide pipes (3);

[0009] The top end of the guide pipe (3) is fixedly connected to the diverter pipe (6);

[0010] A booster oil pump (7) is fixedly connected to the top end of the diversion pipe (6);

[0011] The output port of the booster oil pump (7) is fixedly connected to a detection pipe (8);

[0012] A flow metering tube (11) is fixedly connected to the top end of the detection connecting tube (8);

[0013] An electric throttling valve (9) for adjusting the flow rate inside the flow measuring tube (11) is fixedly connected to one side of the flow measuring tube (11);

[0014] The top end of the flow measuring tube (11) is fixedly connected to a flow meter (12) for detecting the flow rate inside the flow measuring tube (11);

[0015] The flow meter (12) is equipped with a touch control screen (1201);

[0016] The booster oil pump (7), electric throttle shut-off valve (9) and flow meter (12) are electrically connected to the touch control screen (1201);

[0017] The flow detection method includes the following steps:

[0018] S1. Set the boosting parameters of the booster oil pump (7) and the opening and closing time parameters of the electric throttle shut-off valve (9) through the touch control screen (1201);

[0019] S2. Connect the oil supply nozzle (10) detachably to one end of the flow measuring tube (11) and introduce oil into the main flow pipe (1). The oil flows through the main flow pipe (1), pipe connector (2), guide pipe (3), branch pipe (6), booster oil pump (7), and detection connecting pipe (8) to the flow measuring tube (11).

[0020] S3. First, control the booster oil pump (7) to turn on via the touch control screen (1201) to increase the oil flow through the flow measuring pipe (11) to the set booster parameters;

[0021] Then, the touch control panel (1201) controls the electric throttle shut-off valve (9) to open, and the oil in the flow measuring tube (11) is sprayed out through the oil supply nozzle (10);

[0022] The touch control screen (1201) controls the flow meter (12) to detect the flow rate of the oil sprayed from the oil nozzle (10) and displays the flow rate of the oil sprayed from the oil nozzle (10) on the touch control screen (1201);

[0023] The touch control screen (1201) determines whether carbon deposits have occurred in the oil supply nozzle (10) based on the oil flow rate sprayed from the oil supply nozzle (10), and displays the result on the touch control screen (1201).

[0024] When the opening time of the electric throttling valve (9) reaches the set opening and closing time parameter, the touch control panel (1201) controls the electric throttling valve (9) to close.

[0025] Furthermore, the flow detection device also includes a leak-proof connector (4) sleeved on the guide pipe (3);

[0026] The leak-proof connector (4) is equipped with a manual switch valve (5) for adjusting the flow rate in the guide pipe (3);

[0027] When performing step S2 above, after detachably connecting the oil supply nozzle (10) to one end of the flow measuring tube (11), open the manual switch valve (5);

[0028] In step S3 above, after the electric throttling shut-off valve (9) is closed, the manual switch valve (5) is closed.

[0029] The technical effects and advantages of this invention are as follows:

[0030] The flow detection method of this oil supply nozzle is easy to use. During operation, the pressurization parameters of the booster pump and the opening and closing time parameters of the electric throttle valve are set via the touch control panel. The flow meter then detects the oil flow rate through the nozzle. Under a certain oil pressure, the flow meter checks whether the flow rate ejected from the nozzle meets the standard flow rate of the nozzle, and determines whether carbon deposits have formed on the nozzle. The results are displayed on the flow meter.

[0031] Furthermore, by incorporating an electric throttle valve, the oil can be shut off promptly within a specified timeframe via a touch control panel, resulting in more accurate test data.

[0032] This invention can test fuel nozzles of different models and is easy to use. Attached Figure Description

[0049] The output port of the booster oil pump 7 is fixedly connected to a detection pipe 8.

[0050] A flow metering tube 11 is fixedly connected to the top end of the detection tube 8.

[0051] An electric throttling valve 9 for adjusting the flow rate of the oil inside the flow measuring tube 11 is fixedly connected to one side of the tube.

[0053] When in use, the oil supply nozzle 10 is detachably installed at one end of the flow measuring tube 11.

[0054] The flow meter 12 is equipped with a touch control screen 1201.

[0055] The booster oil pump 7, the electric throttling valve 9, and the flow meter 12 are electrically connected to the touch control screen 1201.

[0056] The touch control screen 1201 controls the booster oil pump 7 to boost the oil in the diverter pipe 6 (the boosted oil pressure is set by the booster parameters) and then outputs it to the detection connecting pipe 8.

[0057] The touch control screen 1201 is also used to control the electric throttle shut-off valve 9 to cut off the oil in a timely manner within a specified time (i.e., to set the opening and closing time parameters of the electric throttle shut-off valve 9), so that the detected data is more accurate.

[0058] The touch control screen 1201 is also used to control the flow meter 12 to detect the flow rate of the oil sprayed from the oil nozzle 10 and display it on the touch control screen 1201.

[0059] Example 2:

[0060] This embodiment provides a flow detection method for the oil supply nozzle of the above-mentioned flow detection device, including the following steps:

[0061] S1. Set the boosting parameters of the booster oil pump 7 and the opening and closing time parameters of the electric throttle shut-off valve 9 through the touch control screen 1201.

[0062] S2. First, the oil supply nozzle 10 is detachably connected to one end of the flow metering tube 11 to introduce oil into the main flow tube 1.

[0066] Then, the touch control screen 1201 controls the electric throttle valve 9 to open, and the oil in the flow measuring tube 11 is sprayed out through the oil supply nozzle 10;

[0067] The touch control screen 1201 controls the flow meter 12 to detect the flow rate of the oil sprayed from the oil supply nozzle 10, and displays the flow rate of the oil sprayed from the oil supply nozzle 10 on the touch control screen 1201;

[0068] The touch control screen 1201 determines whether carbon deposits have occurred in the oil supply nozzle 10 based on the oil flow rate sprayed from the oil supply nozzle 10 and displays the result on the touch control screen 1201.

[0069] When the opening time of the electric throttling valve 9 reaches the set opening and closing time parameter, the touch control screen 1201 controls the electric throttling valve 9 to close.

[0070] After the electric throttling shut-off valve 9 is closed, the manual switch valve 5 will be closed.

[0071] Under a certain oil pressure, the flow meter 12 detects whether the flow rate of the oil supply nozzle 10 meets the standard flow rate of the oil supply nozzle, determines whether carbon deposits have occurred in the oil supply nozzle 10, and displays the result on the touch control screen 1201.
