The components of the utility model embodiment described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] Embodiment 1, in combination with Fig. 1, a low-middle-high integrated pressure water supply device, comprising a low zone device a, a middle zone device b, a high zone device c, a water inlet main pipe 1, and a control cabinet 2, the low zone device a, the middle zone device b, and the high zone device c have the same structure, the low zone device a comprises a plurality of Granufi permanent magnet variable frequency integrated pumps 3 and a water outlet pipeline 4, each of the Granufi permanent magnet variable frequency integrated pumps 3 is communicated with the water outlet pipeline 4 through a water pipe, each of the Granufi permanent magnet variable frequency integrated pumps 3 in the low zone device a is communicated with the water inlet main pipe 1 through a water pipe, each of the Granufi permanent magnet variable frequency integrated pumps 3 in the middle zone device b is communicated with the water outlet pipeline 4 of the low zone device a through a water pipe, each of the Granufi permanent magnet variable frequency integrated pumps 3 in the high zone device c is communicated with the water outlet pipeline 4 of the middle zone device b through a water pipe, and the Granufi permanent magnet variable frequency integrated pump 3 is electrically connected with the control cabinet 2.

[0016] The water inlet end of the Granufi permanent magnet variable frequency integrated pump 3 is provided with a valve 5, and the water outlet end is provided with a check valve 6.

[0017] The water outlet pipeline 4 in the low zone device a, the middle zone device b, and the high zone device c is provided with a diaphragm tank 7.

[0018] The water outlet pipeline 4 in the low zone device a, the middle zone device b, and the high zone device c is provided with a pressure gauge 8.

[0019] In the specific implementation, the low zone device a, the middle zone device b, and the high zone device c all comprise three Granufi permanent magnet variable frequency integrated pumps 3, thereby forming a 2-use-1-backup device. The water inlet main pipe 1 is connected to a municipal water supply port to achieve the purpose of water taking of the device; the water flow is divided through a water distribution pipeline; the valve 5 achieves the purpose of opening / closing the valve according to the water flow distribution; the check valve 6 prevents water backflow; the water outlet pipeline 4 achieves the purpose of pressure boosting water supply; the water outlet pipeline 4 is provided with the pressure gauge 8, which has the function of monitoring pressure, and the diaphragm tank 7 has the function of pressure stabilization; and the overall device is controlled through the control cabinet 2.

[0020] The technical scheme logic is illustrated by the figure:

[0021] Since the Granufi permanent magnet variable frequency integrated pump is used in the utility model, it is different from the traditional centrifugal pump, and a Granufi E-motor is used, that is, a frequency controller is built-in the motor, the frequency controller ensures continuous control of the speed change of the pump, and it is possible to set the pump to run at any working point. The target of continuously controlling the speed change of the motor is to adjust the performance of the pump according to the given demand.

[0022] Around the pump characteristics, three-zone devices can be connected in series through a control cabinet, that is, the cost of the control cabinet is reduced, and the three-zone devices are integrated into a set of devices, improving the integration of the device.

[0023] Here, for example, the energy-saving logic of this set of solutions is illustrated. The low zone requires a 60-meter head pressure, the medium zone requires an 80-meter head pressure, and the high zone requires a 100-meter head pressure (1 Mpa);

[0024] Traditional equipment: Since the three zones are independent, when in the low zone pressure demand, a 60-meter head pressure needs to be provided, when in the low and medium zone pressure demand, a total of 60+80=140-meter head pressure needs to be provided, and when in the low, medium and high zone pressure demand, a total of 60+80+100=240-meter head pressure needs to be provided;

[0025] The utility model technical scheme: Since the three zones are in series, when in the low zone pressure demand, a 60-meter head pressure needs to be provided, when in the low and medium zone pressure demand, the power consumption required by the medium zone can be controlled by the frequency of the Grundfos permanent magnet frequency conversion integrated pump, and the low zone pressure is superimposed (stacking pressure), that is, a 20-meter head pressure is superimposed on the basis of the 60-meter head pressure, so that the medium zone water supply demand can be met, and when in the low, medium and high zone pressure demand, similarly, the head pressure required by the high zone can be superimposed (stacking pressure) on the basis of the head pressure of the medium zone, that is, a 20-meter head pressure is increased on the 80-meter head pressure of the medium zone, so that the 100-meter head pressure required by the high zone can be reached;

[0026] Through the above core equipment and the series design different from the traditional equipment, the purpose of energy saving and cost reduction can be achieved.

[0027] In addition, the principle does not change, and 1 standby device can be expanded, such as FIG. 2, or 3 standby devices can be expanded, such as FIG. 3.
