Abstract
The invention provides negative-pressure-free water supply equipment. When the equipment works and the pressure of tap water is normal, a solenoid valve is at a closed position, and a three-way type hydraulic conversion device is opened to communicate a water inlet manifold, so that all pumps in a pump set can be used for supplying water to users through overlapping pressure of the tap water; when the pressure of the tap water cannot meet the utilization of the pressure overlapped pump set, a spare pump in the pump set is automatically controlled by a system to play a role of a booster pump, the solenoid valve is switched on, and the booster pump starts to work; the pressure of the booster pump enforces the three-way type hydraulic conversion device to be closed so that the booster pump can be used for boosting reserved water in a water tank and supplying the water to the pressure overlapped pump with the tap water through the three-way type hydraulic conversion device at the same time, so as to overcome a phenomenon that the pressure of the tap water is not enough; the operation condition of the pressure overlapped pump basically keeps unchanged and the aim of saving energy is realized.
Description
Technical field
The present invention relates to a kind of no-negative-pressure water supply equipment, particularly a kind of box-type water supplying equipment without negative.
Background technology
Box-type water supplying equipment without negative in prior art generally has 2 kinds of frame modes, a kind ofly at water outlet of water tank, install a small-sized booster pump additional and laminate series connection of pumps, when appearring in solution tap water, negative pressure will after Water in Water Tank supercharging, meet the pump discharge demand that laminates, laminate pump lift and can deduct tap water pressure and reduce power, but that the shortcoming of this mode is manufacturing cost is large, installation strength is high, control mode is difficult, water pressure fluctuations is large.Another kind of mode is not for configuring booster pump, laminating pump increases, when tap water produces negative pressure, laminates pump by total head allocating power and be converted to water tank water suction, this mode can reduce the configuration of booster pump but water pump operation in 2 kinds of operating modes (water inlet have press and with no pressure), 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 box-type water supplying equipment without negative, reduce manufacturing cost, reduce installation strength, energy consumption while simultaneously reducing water pump operation.
The present invention adopts following structure to realize above-mentioned purpose, no-negative-pressure water supply equipment by: laminate pump group, tap water protective device, water tank, three way type waterpower switching device shifter, electromagnetic valve, switch board and form.Water inlet is connected with tap water by tap water protective device to laminate pump group; by laminating after stand by pump in pump group is defined as booster pump water inlet manifold, be connected with water tank; water inlet manifold separates stand by pump and the water inlet of other booster pump by three way type waterpower switching device shifter, simultaneously being connected with water inlet manifold with three way type waterpower switching device shifter by electromagnetic valve with delivery port this pump.
Adopt as above structure, in equipment when work, is when tap water pressure is normal, electromagnetic valve is in the closed position, three way type waterpower switching device shifter is opened and is made water inlet manifold UNICOM, at this moment all pumps in pump group can be superposeed and be supplied water to user by tap water pressure, when tap water pressure can not meet when laminating pump group and using, at this moment the stand by pump in the automatic control pump group of system serves as booster pump role, electromagnetic valve is opened, booster pump is started working, the pressure of booster pump forces three way type waterpower switching device shifter to be closed, booster pump can will be given and be laminated water supplying pump by three way type waterpower switching device shifter while and tap water after the deposit water supercharging in water tank like this, alleviate the hypodynamic phenomenon of running water pressure, the operation condition that makes to laminate pump is substantially constant, reach energy-conservation object.
Accompanying drawing explanation
Fig. 1 is enforcement state diagram of the present invention.
The specific embodiment
A kind of no-negative-pressure water supply equipment as shown in Figure 1 comprises: water tank 1, laminate pump group 2, tap water protective device 3, waterpower switching device shifter 4, electromagnetic valve 8, switch board (being mark in figure) and valve form, the water inlet that laminates pump group 2 is connected with water inlet manifold 6, tap water is passed through after tap water protective device 3 and float valve 5 by interface 7, be connected with water tank 1 and water inlet manifold 6 respectively, the water pump quantity that laminates pump group 2 can arrange many according to flow system flow size, the water outlet that laminates pump group 2 connects with outfall sewer 9, service pipe is connected with outfall sewer 9, selection laminates stand by pump 10 in pump group 2 as booster pump, waterpower switching device shifter 4 is installed on water inlet manifold 6 separates the water inlet of stand by pump 10 and other pump, one way valve 11 is installed between water inlet manifold 6 and water tank, the water inlet of stand by pump 10 is connected with water inlet manifold 6 by transfer valve 4 is rear, by one way valve 11, be connected with water tank simultaneously, the delivery port of stand by pump 10 is connected with water inlet manifold 6 with after electromagnetic valve 8 by threeway, when tap water pressure waterpower switching device shifter 4 is opened, electromagnetic valve 8 cuts out, tap water is flowed to and is laminated pump group 2 by water inlet manifold 6 by tap water protective device 3 like this, at this moment every the pump laminating in pump group 2 can carry out the object that overlapped supercharging reaches energy saving water supply.When tap water pressure underfed, the aperture of tap water protective device 3 diminishes gradually, at this moment electromagnetic valve 8 is opened, stand by pump 10 is started working, waterpower switching device shifter 4 is subject to the external force of stand by pump 10 and cuts out the interface channel of water inlet manifold 6 and stand by pump 10, the stand by pump 10 laminating in pump group 2 just serves as booster pump work temporarily, deposit water in water tank 1 is entered into water inlet manifold 6 after by stand by pump 10 superchargings, make to laminate pump and use tap water and water tank deposit water simultaneously, reach and meet user's instructions for use and the object of peak regulation, when tap water pressure recovers normal, system is got back to again initial state, with this periodic duty.Not impact equipment supplies water when making tap water cut-off; water inlet pipe 12 has also been installed on water inlet manifold 6; between water inlet pipe 12 and water inlet manifold 6, flap valve 13 is installed; when tap water can not meet overlapped supercharging or cut off the water; tap water protective device 3 cuts out automatically into water; at this moment all pumps that laminate in pump group 2 can directly be fetched water by water tank, reach user's water and not affected by tap water cut-off.
