The series connection of the low-zone energy-saving pump device 61, the low-zone pump house device 01, and the middle-zone pump house device 02 can automatically adjust the flow and pressure of the low zone and the middle zone according to water demand, the high-zone energy-saving pump device 62 is directly connected to the high-zone pump house device 03, can accurately supply water according to the water use characteristics and pressure demand of the high zone, centrally provides sufficient lift to ensure stable water supply of the high zone, and since the water pressure requirements of the low zone and the middle zone are small, the secondary pressurization can be completed by a single set of energy-saving pump device.

[0026] Preferably, the low zone energy-saving pump equipment 61 outlet pipeline is provided with a pressure reducing valve 022, which is arranged between the low zone outlet pipe network 011 and the medium zone outlet pipe network 021 on the low zone energy-saving pump equipment 61 outlet pipeline.

[0027] Preferably, the second section 3 of the main pipeline is provided with a filter 11, a total valve 12, a flexible joint 13 and an electric butterfly valve 14. Specifically, the filter 11, the total valve 12, the flexible joint 13 and the electric butterfly valve 14 are all arranged on the second section 3 of the main pipeline between the first section 1 and the installation point of the parallel pipeline 4. The filter 11 is used to filter impurities and particulate matters in the fluid flowing through the second section 3 of the main pipeline, so as to prevent impurities from entering the subsequent pipeline or equipment, thereby protecting the normal operation of the system. At the same time, the filter 11 can also play a role in stabilizing the fluid pressure and flow in the system.

[0029] Preferably, the outlet pipelines of the low zone energy-saving pump equipment 61 and the high zone energy-saving pump equipment 62 are both provided with check valves 601.

[0030] In summary, the low zone energy-saving pump equipment 61 and the high zone energy-saving pump equipment 62 jointly constitute a secondary pressurizing pump house equipment, and the low zone water outlet pipe network 011, the middle zone water outlet pipe network 021 and the high zone water outlet pipe network 031 jointly constitute a water outlet pipe network system; the low zone pump house equipment 01, the middle zone pump house equipment 02 and the high zone pump house equipment 03 jointly constitute a primary pressurizing system;

[0031] The water inlet pipe of the secondary pressurizing pump house equipment is connected with the tap water pipe network and the tap water pool, water is pressed into the water inlet pipe of the secondary pressurizing pump house equipment under the residual pressure of the tap water pipe network, the pressurizing water pump of the equipment continues to pressurize on the basis of the residual pressure of the water inlet, and water is supplied to the water outlet pipe network system after the water supply pressure is increased to the pressure required by the user;

[0032] When the water consumption of the user is greater than the water supply capacity of the tap water pipe network, the primary pressurizing system is insufficient to provide the water lifting pressure, so that the municipal water inlet pipe network pressure decreases (the municipal water inlet pipe network pressure is detected by the municipal pipe network pressure detection control device at the water inlet of the secondary pressurizing pump house equipment), when the water inlet pressure of the secondary pressurizing pump house equipment decreases to less than 0.2MPA, the device municipal pipe network pressure detection control device opens the valve corresponding to the water outlet pipe of the water storage pool 2, and the water storage pool 2 pressurizes the water inlet of the equipment, so that the water inlet pipe network pressure is prevented from decreasing and adversely affecting the tap water pipe network.

[0033] When the water supply capacity of the tap water pipe network recovers, or the water consumption of the user decreases, and the water inlet pipe network pressure recovers to above the protection pressure, the water inlet of the equipment is automatically switched to the municipal pipe network, that is, the valve corresponding to the water outlet pipe of the water storage pool 2 is closed, and the pipe network pressure supply is restored; at this time, the secondary pressurizing pump house equipment automatically enters the dormant state, and the user is directly supplied with water by the tap water pipe network and the primary pressurizing system.

[0034] When the user does not use water or the water consumption is very small, the equipment automatically enters the shutdown dormant state, and the tubular tank body (equivalent to the function of a pressure stabilizing tank) connected with the secondary pressurizing pump house equipment (the low zone energy-saving pump equipment 61 and the high zone energy-saving pump equipment 62) maintains the small amount of water used by the user and the pipe network leakage; when the pressure stabilizing tank cannot maintain the pressure required by the water supply pipe network, the equipment automatically wakes up and resumes normal operation.

[0035] During the operation of the equipment, the residual pressure of the tap water pipe network is fully utilized, the user demand is met all-weather without adversely affecting the tap water pipe network, the water supply energy consumption is reduced, and the optimal operation of the water supply system is realized.
