In addition, terms such as "first", "second", "third", etc. are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0017] Refer to Figure 1 As shown, in a preferred embodiment, the fuel injection pipe hydraulic test device of the present utility model includes a manual hydraulic pump 1, a compound connector 2, and a hydraulic pressure gauge 3. The compound connector 2 has a plurality of connection ends. The compound connector 2 is respectively connected to the manual hydraulic pump 1, the hydraulic pressure gauge 3, and the high-pressure oil pipe 0 to be tested. Both ends of the high-pressure oil pipe 0 to be tested are fixedly connected with combined joints.

[0018] Furthermore, the combined joint includes a threaded socket 4, a quick connector 5, and a first adapter joint 6 that are combined and connected to each other.

[0019] A second adapter joint 7 is provided between the manual hydraulic pump 1 and the compound connector 2. To improve the connection sealing performance, PTFE tape is wrapped around the outside of the adapter joint.

[0020] During the test, inject appropriate test oil into the manual hydraulic pump 1, and connect the hydraulic pump, double connector 2, oil pipe, quick connector, etc. in sequence according to the drawing. First, pump the pressure slowly. When the pressure rises to 100 bar, observe whether the pressure is stable after 30 seconds. Pump the oil to 500 bar and keep the pressure stable for 1 minute to confirm that the pipeline connection is effective. The maximum test pressure value of the high-pressure oil pipe 0 to be tested shall not exceed 700 bar. It should be noted that the test oil needs to be replenished in time after it is used up during the test.
