[0003] 1. The problem that it is difficult for the equipment to absorb water when used on site. When there is a height difference between the water storage tank or the on-site water pool and the high-pressure water pump, and the high-pressure water pump is at a high position, due to the lack of a self-priming device in the pump body itself, the water pump cannot pump water, and the pressure test operation cannot be completed.

[0004] 2. During the implementation of disinfection (sodium hypochlorite), it is necessary to dilute and add it to the pipeline on site. There are potential safety hazards during the disinfection addition process. Explosions, leaks, and immersions may all involve personal corrosion accidents, presenting safety hazards.

[0005] Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to make improvements to the prior art. Content of the Utility Model

[0016] Further, the water inlet of the water storage tank is connected to the network water.

[0017] Further, the high-pressure pump is electrically connected to a generator set.

[0018] Compared with the prior art, the water supply pipe pressure test and disinfection machine of the present utility model includes a water storage tank, a vacuum water suction tank, a high-pressure pump, a flow control valve and a water injector connected in sequence. The liquid inlet of the water injector is connected to the sodium hypochlorite stock solution pipe, the water inlet of the water injector is connected to the flow control valve, and the water outlet of the water injector is connected to the first newly installed pressure test pipe. The vacuum water suction tank generates vacuum by sucking water from the top and pumping water from the bottom, which perfectly solves the problem of pumping water, achieves continuous water inlet without interruption, ensures that the output pressure meets the requirements of pipeline pressure test.
