Intelligent pump station

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 ...

[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 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 according to the full head configuration, and when the tap water pressure is insufficient, the stacked pump is switched to the water tank to absorb water. This way can reduce the configuration of the booster pump, but the water pump will run In two working conditions (water inlet with pressure and no pressure), the energy saving effect of the pump is not as good as the first one when it is running
