Boosting pressure superposing water supply equipment for tank

Abstract

The invention discloses boosting pressure superposing water supply equipment for a tank. When the equipment works and the pressure of tap water is normal, a control valve between the water inlet of a booster pump and a water inlet manifold is opened, and a control valve between the water outlet of the booster pump and the water inlet manifold is closed, and all pumps in a pump package can supply water to users through pressure superposition of the tap water; when the pressure of the tap water cannot meet the requirement of the pressure superposing pump package, a system automatically controls a standby pump in the pump package to serve as the booster pump, the control valve between the water inlet of the booster pump and the water inlet manifold is closed and the control valve between the water outlet of the booster pump and the water inlet manifold is opened, so that water stored in a water tank is boosted by the booster pump, and, together with the tap water, is supplied to a pressure superposing pump, and the phenomenon that the pressure of the tap water is insufficient is avoided; meanwhile, the working condition of the pressure superposing pump is not changed basically, and the aim of saving energy is fulfilled.

Description

technical field [0001] The invention relates to a box-type laminated pressure water supply equipment, in particular to a pressurized box-type laminated pressure water supply equipment. Background technique [0002] The box-type superimposed water supply equipment in the prior art generally has two structural modes. One is to install a small booster pump and superimposed pump in series at the water outlet of the water tank to solve the problem of insufficient tap water to pressurize the water in the water tank to the tap water pressure. To meet 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 method, 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 w...

[0002] The box-type superimposed water supply equipment in the prior art generally has two structural modes. One is to install a small booster pump and superimposed pump in series at the water outlet of the water tank to solve the problem of insufficient tap water to pressurize the water in the water tank to the tap water pressure. To meet 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 method, 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
