[0035] Working principle: When the device needs to be pressure tested, first move the electric pressure test pump to the position where the pressure test is required through the moving wheel 2. The locking screw 9 can ensure the stability of the connection between the mounting cover 5 and the components arranged on the mounting cover 5 during the movement. Then rotate the locking screw 9 so that the locking screw 9 releases the restriction on the moving component 21. Then place the mounting cover 5 horizontally. The hinge at the connection between the mounting cover 5 and the mounting box shell 1 supports the horizontal state of the mounting cover 5. By rotating the wheel 8, the threaded rod 15 is driven to rotate, so that the mounting base 16 moves under the guidance of the sliding track rod 14, thereby driving the high-pressure pump 17 to move horizontally. When the high-pressure pump 17 moves to the position where the connecting pipe 2 18 can be connected to the connecting pipe 1 13, the pipe connecting fastener 19 is rotated to make the pipe connecting fastener 19 Fix the connecting pipe 2 18 and the connecting pipe 1 13 to connect the high-pressure pump 17 and the pressure regulating assembly 11, so that the device can be pressure tested. The pressure regulating assembly 11 is connected to the water tank 10 through the connecting pipe to ensure sufficient water supply during the pressure test. Then, close the installation cover 5, start the high-pressure pump 17, pump water from the water tank 10, and adjust the pressure through the pressure regulating assembly 11. The regulated high-pressure water enters the pipe or equipment to be pressure tested through the connecting pipe. The pressure change can be monitored by the pressure gauge 12 to ensure that the pressure test process is carried out within a safe range. Open the drain cover 20 on the drain outlet 3 to drain the residual water in the pressure test pump for next use. At the same time, the water tank 10 can be cleaned and maintained through the water tank cover to ensure the long-term use of the pressure test pump.
