In the frequency conversion speed regulation pump package water supply scheme, according to the level of super high-rise building, divide into a plurality of water supply district, the hypothesis: for i water supply pressure zones, the water supply level of each pressure zone is Mi, and the water supply configuration is generally as follows:
i =1 area, water supply level M1 (typically from underground to two-stories), supplied directly by municipalities;
i =2 area, water supply level M2, variable frequency water supply;
i =3 area, water supply level M3, variable frequency water supply;
and so on.
The lift flow of the variable-frequency speed-regulating pump set is respectively taken according to the standard requirement.
In the scheme of combining the water pump and the water tank with the gravity water supply, a gravity water supply living water tank is generally arranged on a refuge layer, the capacity of the water tank is calculated according to the standard requirement, the water tank is made of stainless steel materials, and the water tank is divided into two water tanks with basically equal capacity. According to the level of the super high-rise building and the condition of the refuge layer, the water supply area is divided into a plurality of water supply areas.
Suppose that: the height of the super high-rise building is n: there are i water supply areas of the water tank, the water supply level of each water supply pressure area is Mi, and the water supply configuration is generally as follows:
i =0 region: the underground pump room is provided with a water inlet tank and a lifting pump set;
i =1 region: the gravity water supply domestic water tank is supplied with water by a lifting transfer water pump in an i =0 area, the gravity water supply domestic water tank in the i =1 area supplies water to a level M1 through gravity, and a pressure reducing valve bank is arranged on an overpressure floor; meanwhile, a pump room of the i =1 area is provided with a lifting pump set to supply water to a water tank of the i =2 area;
i =2 region: the gravity water supply domestic water tank is supplied with water by a lifting transfer water pump in an i =1 area, the gravity water supply domestic water tank in the i =2 area supplies water to a level M2 through gravity, and a pressure reducing valve bank is arranged on an overpressure floor; meanwhile, a pump room of the i =2 area is provided with a lifting pump set to supply water to a water tank of the i =3 area;

And a pressure reducing valve bank is arranged on the overpressure floor. Mn level water supply is realized, and water is supplied by a variable-frequency speed-regulating pump set combined with an air pressure tank through a gravity water supply domestic water tank in an i = n area.
