Abstract
The invention relates to pressure-superposed water supply equipment with a water replenishing function. When the equipment works and the pressure of tap water is normal, a water inlet electric valve and a switching electric valve are simultaneously turned on, and a water replenishing electric valve is turned off, and a pumping set operates at variable frequencies to carry out the superposed pressure boosting to supply water to users, accordingly, the pumping set can carry out the superposed pressure boosting based on the pressure of tap water to achieve the energy saving purpose. When the tap water pressure and flow cannot meet the use requirement of users, the switching electric valve is turned off, the water replenishing electric valve is turned on, a pressure boosting superposed pump changes to pump water from a water tank, and the water outflowing pressure of the pressure boosting superposed pump is automatically adjusted by a system, so that the water outflowing pressure and the tap water pressure are matched, and the superposed pump is enabled to be simultaneously supplied by the tap water and the water from the water tank, and thus water use requirements of the users are met and simultaneously the tap water is enabled to not generate negative pressure.
Description
Technical field
The present invention relates to a kind of pressure-superposed water supplying facility, particularly a kind of band water tank moisturizing pressure-superposed water supplying facility.
Background technology
The pressure-superposed water supplying facility of the band water tank moisturizing in prior art generally has 2 kinds of frame modes, one installs a small-sized booster pump additional at water outlet of water tank and laminates series connection of pumps, solve tap water not enough time Water in Water Tank is pressurized to tap water pressure and meets and laminate pump discharge demand, laminate pump lift can deduct tap water pressure and reduce power, but the shortcoming of this mode to be manufacturing cost large, installation strength is high, control mode is difficult, water pressure fluctuations is large.Another kind of mode is not for configure booster pump, laminate pump to increase by total head allocating power, being converted to water tank water suction when tap water pressure is not enough by laminating pump, this mode can reduce the configuration of booster pump but water pump operation is in 2 kinds of operating modes (water inlet have pressure and with no pressure), and during water pump operation, energy-saving effect is not so good as the first.
Summary of the invention
The object of the invention is to: design a kind of utilization laminate pump superposition moisturizing pressure-superposed water supplying facility, to tap water do not produce negative pressure, reduce manufacturing cost, reduce installation strength, simultaneously reduce water pump operation time energy consumption.
The present invention adopts following structure to realize above-mentioned purpose, a kind of moisturizing pressure-superposed water supplying facility by: pump group, water inlet motor operated valve, water tank, switching motor operated valve, moisturizing motor operated valve, switch board forms and pipe valve forms.In pump group, pump is divided into and laminates pump and supercharging laminates pump, pump group water inlet manifold is connected with tap water by water inlet motor operated valve, be connected with water tank by one way valve simultaneously, switching motor operated valve is arranged between water inlet manifold pump group, the water outlet of pump group is by one way valve by outfall sewer UNICOM, and supercharging laminates delivery side of pump simultaneously by moisturizing motor operated valve and laminate pump water inlet UNICOM.
Adopt as above structure, during equipment work when tap water pressure is normal, water inlet motor operated valve and switching motor operated valve are opened simultaneously, moisturizing motor operated valve cuts out, the capable overlapped supercharging that carries out of pump group frequency conversion cloud can carry out overlapped supercharging to user's water supply, at this moment pump group on the pressure-based of tap water, reaches energy-conservation object.When tap water pressure flow can not meet user use time, at this moment switch that motor operated valve cuts out, moisturizing motor operated valve opens supercharging and laminate pump and change and draw water from water tank, system automatically adjusts supercharging and laminates and pump water pressure, its discharge pressure and tap water pressure are matched, ensure that booster pump is supplied by tap water and Water in Water Tank simultaneously, meet user's use water with this and ensure that tap water does not produce negative pressure simultaneously.
Accompanying drawing explanation
Fig. 1 is enforcement state diagram of the present invention.
Detailed description of the invention
A kind of moisturizing pressure-superposed water supplying facility as shown in Figure 1 comprises: water tank 1, pump group 2, water inlet motor operated valve 3, switch motor operated valve 4 and moisturizing motor operated valve 5, switch board (not marking in figure) and valve composition, pump group 2 laminates pump 7 form by laminating pump 6 and supercharging, tap water is connected with water tank 1 by float valve 8, be connected with water inlet manifold 9 by water inlet motor operated valve 3 simultaneously, water inlet manifold 9 is provided with and switches motor operated valve 4, supercharging is laminated pump and is connected with water tank 1 by one way valve 10, pump group 2 water outlet is connected with outfall sewer 11, one way valve 12 is installed in outfall sewer 11, the delivery port that supercharging laminates pump 7 is connected by the water inlet manifold 9 of moisturizing motor operated valve 5 with the side laminating pump 6 simultaneously, make it the water inlet UNICOM with laminating pump 6.During equipment work, tap water carries out moisturizing deposit by float valve 8 feed tank 1, motor operated valve 3 of simultaneously intaking is opened with switching motor operated valve 4, pump group 2 startup optimization, pump group 2 determines the input amount of pump according to water supply volume, at this moment pump group 2 is carried out overlapped supercharging and is supplied water to user on tap water pressure basis, reaches energy-conservation object.When tap water intake pressure flow change can not meet user's instructions for use time, at this moment switch motor operated valve 4 to close, moisturizing motor operated valve 5 is opened, and supercharging laminates pump 7 and drawn water by water tank 1, and it is equal that the pressure of supercharging stabilized pressure pump 7 is automatically set as same tap water intake pressure by switch board.Laminate pump 6 so simultaneously to laminate pump 7 by tap water and supercharging the water yield is provided, meet user's instructions for use, avoid tap water to intake simultaneously and occur negative pressure appearance.System can laminate the quantity of pump according to user's request configuration.
