[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example

[0025] like Figure 1 、 2As shown in Figure 3, the portable hydraulic testing equipment of this embodiment includes a movable packaging box 1, a boosting device 2, a diverter 3, a pressure measuring device 4 and a mounting plate 14. The front side of the packaging box 1 is provided with a box door 11 that can be opened or closed. The mounting plate 14 can be detachably installed in the packaging box 1. The side walls and bottom walls of the packaging box 1 are respectively provided with a medium outlet 5 and a pressure relief port 6. The boosting device 2, the diverter 3 and the pressure measuring device 4 are respectively installed on the front side of the mounting plate 14. The diverter 3 has one inlet and three outlets. The outlet of the boosting device 2 is connected to the inlet of the diverter 3 through a pipeline. One outlet of the diverter 3 is connected to the pressure measuring device 4 through a pipeline. The remaining two outlets of the diverter 3 are respectively connected to the medium outlet 5 and the pressure relief port 6 through pipelines. A control valve 7 is provided on the pipeline connecting the pressure relief port 6 and the outlet of the diverter 3.

[0026] The portable hydraulic test equipment of this embodiment integrates the core components and pipelines for testing on a mounting plate 14 within a single packaging box 1. This convenient portability allows the entire device to be easily moved to the target site for testing. The overall structural design is simple and rational, and the device is compact, lightweight, and easy to operate. Furthermore, the core testing units are mounted on the mounting plate 14, allowing the entire mounting plate 14 to be removed during inspection and maintenance, facilitating routine maintenance and component replacement outside the device. The overall design is modular.

[0027] The specific usage process is as follows:

[0028] After the entire equipment is transported to the target site, the inlet of the booster device 2 is connected to the medium delivery pipeline. The chamber door 11 is opened, and the medium outlet 5 is connected to the pressure-bearing valve or pipeline product to be tested via a pipeline. The booster device 2 is then operated to apply pressure, and the medium is injected into the product under test through the diverter 3 and the medium outlet 5. During this process, the pressure measuring device 4 can perform real-time pressure detection. Continuous pressure is applied, causing the internal pressure of the test product to continuously increase. The pressure value is measured in real time by the pressure measuring device 4 to see if it reaches the predetermined test pressure value. If so, the booster device 2 is stopped. During this period, the pressure inside the test product is maintained. If the test product is leaking, the real-time pressure data of the pressure measuring device 4 will decrease; otherwise, it remains unchanged, thereby determining whether the test product has passed the test. After the test is completed, the control valve 7 is operated to open the circuit, and the fluid is discharged through the control valve 7 and the pressure relief port 6 until the entire circuit pressure reaches zero. At this point, the test product can be removed and the chamber door 11 is closed.

[0029] In this embodiment, a plurality of running wheels 12 are provided at the bottom of the packaging box 1, so that the entire device can be moved along the ground, making it more convenient to move.
