Problems solved by technology

[0002] In the prior art, there are generally two structural modes for the superimposed water supply pump station with water tank replenishment. One is to install a small booster pump at the outlet of the water tank and connect the superimposed pump in series to solve the problem of pressurizing the water in the water tank when the tap water is insufficient. Until the tap water pressure meets the flow requirements of the stack pump, the head of the stack pump can be reduced by subtracting the tap water pressure to reduce the power, but the disadvantages of this method are high manufactur

Embodiment Construction

[0007] Such as figure 1 The shown intelligent pumping station includes: housing 1, water pump unit 2, running water protection device 3, energy-saving converter 4, control cabinet (not marked in the figure) and valves, housing 1 is divided into equipment room 5 and storage The water room 6, the tap water is connected to the water storage room 6 through the float valve 7, the water pump unit 2 is divided into a superimposed pump 8 and a supercharged superimposed pump 9, the energy-saving converter 4 is provided with three interfaces that can be the same for two or two, and the tap water protection The device 3 adopts hydraulic control, the higher the tap water pressure is, the larger the opening is, and the more the flow is. Between the stack pump 8 and the booster stack pump 9, the water inlet main pipe 10 is connected to the tap water inlet 11 through the tap water protection device 3, and the water inlet main pipe 10 passes through the one-way valve 12 and the one-way valve ...

Abstract

The invention provides an intelligent pump station. When equipment works, a tap water protection device is hydraulically controlled; when the pressure of tap water is higher, the opening degree is greater and the excess flow is more; when the pressure of the tap water is normal, the tap water protection device is automatically started and an energy-saving converter is started simultaneously; a water pump set is operated in a frequency conversion manner to overlap and pressurize so as to supply water to a user; each pump in the water pump set can carry out overlapping and pressurizing to supply the water on the basis of the pressure of the tap water, so that the aim of saving energy is realized. When the pressure of the tap water is reduced and the flow cannot meet the requirements of the user, the opening degree of the tap water protection device is reduced to prevent the pressure of the tap water from being continually reduced and the energy-saving converter is controlled by a system to work; inflowing water of an overlapping and pressurizing pump is disconnected with the tap water and effluent water of the overlapping and pressurizing pump is communicated with the tap water, so that the overlapping and pressurizing pump pumps water from a water tank; the pressure of the effluent water of the overlapping and pressurizing pump is automatically adjusted, so that the pressure of the effluent water is matched with the inflowing water pressure of the tap water; therefore, the tap water and the water stored in the water tank can be supplied to the overlapping and pressurizing pump at the same time, the water requirement of the user is met and the negative pressure is not generated by the tap water.

Description

technical field [0001] The invention relates to an intelligent water supply pumping station, in particular to a superimposed water supply pumping station with a water tank. Background technique [0002] In the prior art, there are generally two structural modes for the superimposed water supply pump station with water tank replenishment. One is to install a small booster pump at the outlet of the water tank and connect the superimposed pump in series to solve the problem of pressurizing the water in the water tank when the tap water is insufficient. Until the tap water pressure meets the flow requirements of the stack pump, the lift of the stack pump can be reduced by subtracting the tap water pressure to reduce the power. However, the disadvantages of this method are high manufacturing cost, high installation strength, difficult control methods, and large water pressure fluctuations. Another way is not to configure a booster pump, the power of the stacked pump is increased ...
