Problems solved by technology

[0002] Traditional non-negative pressure frequency conversion water supply systems mostly use steady flow tanks and vertical multi-stage centrifugal water pumps, which are controlled by frequency conversion speed regulation technology. The water pumps are installed outside the water pipes. The installation requires a special foundation base, which occupies a large area and costs equipment. high

Embodiment 1

[0022] Figure 1~3 Is the best embodiment of the present invention, with reference to the attached Figure 1~3 :

[0023] Suspended silent and non-negative pressure frequency conversion automatic water supply equipment mainly includes a steady flow tank 6, a water inlet 13, a water outlet 3, a submersible pump 7, a water pump casing 8, an upper water pipe 12 and a steady flow tank bracket 16. The steady flow tank 6 is installed on the steady flow tank bracket 16, the top is provided with a negative pressure valve 1, the bottom of the steady flow tank 6 is provided with a water inlet 13, the water inlet 13 is connected to the main water inlet pipe 14, and the main water inlet pipe 14 is provided with Six ports, the upper port is connected to the lower end of the upper water pipe 12, the lower port is connected to the sewage outlet 19, the other three ports are connected to the lower ends of three water pump casings 8, the upper end of the upper water pipe 12 is inserted into t...

Embodiment 2

[0027] Both sides of the steady flow tank 6 are symmetrically provided with two groups of pumps in pipes. The working principle and working process are the same as those in Embodiment 1.

Embodiment 3

[0029] There are 4 sets of pipe-in-pipe pumps evenly distributed around the steady flow tank 6. The upper ports of the 4 pump casings 8 are inserted into the main water outlet pipe 17 symmetrically along the direction of the water outlet, and communicate with the main water outlet pipe 17. The lower ports are connected to the main water inlet pipe 14. connected. The working principle and working process are the same as those in Embodiment 1.
