Embodiment
Non-negative-pressure variable frequency of the present utility model energy-conservation water work is described in more detail below in conjunction with schematic diagram,
Which show preferred embodiment of the present utility model, it should be appreciated that those skilled in the art can change described here reality
With new, and still realize advantageous effects of the present utility model.Therefore, description below is appreciated that for art technology
Personnel's is widely known, and is not intended as to limitation of the present utility model.
As shown in Figures 1 to 5, the utility model proposes non-negative-pressure variable frequency save water work, including a base 8, peace
Loaded on the steady-flow tank 7 on base 8, the steady-flow tank 7 is provided with two lifting ear K, for lifting by crane steady-flow tank 7, multigroup installation
In the main pump unit 3 of base 8, it is therefore preferable to two groups or three groups of main pump units 3, in order to mitigate vibration when main pump unit 3 is run
And noise can set up elastic shock buffering mechanism between main pump unit 3 and the base 8, for the ease of describing, in the present embodiment
Using three groups of main pump units 3, the outlet connecting pipe road of each main pump unit 3 is sequentially installed with 90 ° of elbows 9, the first wafer type non-return
Valve 10, the wafer type butterfly valve 12 of connecting hose 11 and second, the ports of export of three groups of main pump units 3 are connected to outfall sewer 2 jointly, it is described go out
The one end of supply mains 2 is provided with blind plate 1, and the access connecting line of three groups of main pump units 3 is connected with the He of the second Wafer Check Valves 4 in turn
Second wafer type butterfly valve 5, the access connecting line of multigroup main pump unit 3 are connected to water inlet pipe 6 jointly, and the water inlet pipe 6 connects
The steady-flow tank 7 is connected to, water inlet manifold flange is installed between the water inlet pipe 6 and the steady-flow tank 7.
