Description

Technical Field

[0001] The present invention relates to the technical field of water supply auxiliary equipment, and in particular to a low-energy consumption water supply device. Background Art

The characteristics of domestic water supply are large fluctuations in flow demand and long water supply time at small and medium flows. Conventional booster pumps have low efficiency and high energy consumption under small and medium flow conditions. For booster pumps, at 25% of the rated flow, the pump efficiency drops by about half, which means that under the conditions of the same water supply pressure and water supply volume, the energy consumption of small flow water supply is twice or even more than that of large flow water supply, which results in energy waste.

[0003] After searching, the patent with application number 201910496596.1 discloses an energy-saving water supply equipment, including a flow stabilizing tank, a booster pump unit, a check valve, and a control cabinet.

When the water replenishment pump 109 is running at full load but is not enough to replenish water, the water replenishment pump 2 1011 is turned on. The standby pump 1012 serves as a timely replacement when the water replenishment pump 1 109 or the water replenishment pump 2 1011 fails, thereby ensuring the stability of water delivery by the water replenishment pump 2 1011.

[0038] Embodiment 3

[0039] like Figure 1 and 8 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the water replenishment pump 1 109, the water lifting pump 1010, the water replenishment pump 2 1011 and the standby pump 1012 are all mounted on the top surface of the mounting base 101. The middle part of the water filling pipe 1013 is also connected to a maintenance section 1014 for dredging and cleaning the equipment through a coupling.

[0040] In this embodiment, an inspection section 1014 is provided in the middle of the water filling pipe 1013, so as to facilitate the maintenance and dredging of the water supply equipment body 1, and well ensure that the water supply equipment body 1 is more stable during operation.

[0041] Embodiment 4

Preferably, the gas supply mechanism 12 includes a connecting pipe 121 that is fixed on the bottom surface of the floor equipment room, the connecting pipe 121 is in conflict with the uppermost water supply main pipe 3, and a gas injection branch pipe 122 is fixed on the top side of the connecting pipe 121. The inner wall of the gas injection branch pipe 122 is installed with a solenoid valve. The upper side of the gas injection branch pipe 122 is connected to the gas injection main pipe 123, and the top side of the gas injection main pipe 123 is connected to the hollow column 124. The outer side of the hollow column 124 is provided with The gas tank 125 is provided with a support 126 on the side of the gas tank 125 facing away from the hollow column 124. The top side of the support 126 is fixed with an electric telescopic rod 127 by screws.

The output end of the electric telescopic rod 127 extends into the adjacent gas tank 125 and a piston head 128 is fixed at the end. An air guide pipe 129 is connected between the gas outlet end of the gas tank 125 and the outer wall of the hollow column 124.

[0043] In this embodiment, when supplying gas, the solenoid valve on the gas injection branch pipe 122 is opened according to the set flow condition. After opening, the electric telescopic rod 127 drives the piston head 128 to move so that the gas in the gas tank 125 is input into the airbag inflation rod 10. At this time, the airbag inflation rod 10 is inflated, thereby achieving a rapid change in the water delivery volume in the water supply main pipe 3, thereby ensuring the adjustment rate of the device under small and medium flow conditions. When deflated, the piston head 128 moves back. At this time, the water pressure presses the gas back into the gas tank 125, and the solenoid valve is closed to wait for the next small and medium flow condition to adjust the water supply in the water supply main pipe 3 again.

[0049] In this embodiment, the airbag inflation rods 10 are distributed in three vertical rows, and the single rows are independent of each other, so as to facilitate the multi-stage adjustment of the water supply amount of the water supply main 3, thereby satisfying the requirements of the water supply equipment body 1 for diversified water supply, thereby greatly improving the flexibility of the device.
