Description of drawings
Fig. 1 is the principle schematic of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done and to be described in further detail.
Please refer to shown in Figure 1, the pump group comprises three main pumps 15 and an auxilliary pump 14 in the pipe of the utility model preferred embodiment, in other embodiments, the quantity of main pump 15 and auxilliary pump 14 is not limited thereto, main pump 15 all is connected with the electrical control center 11 of its running status of control with auxilliary pump 14, wherein pump in the pipe of the super-silent stainless prior art of main pump 15 employings; Auxilliary pump 14 be a low-capacity pump, and lift and every performance are close with main pump 15, at little water yield water or come into operation night, guarantees that system operates in the high efficiency point, the raising energy-saving effect.
One end of the water inlet collecting fitting 13 of main pump 15 and auxilliary pump 14 is by being responsible for the water side that valve 12 is connected in current stabilization adjuster 10, the effect of the warm special valve 9 that is provided with on the current stabilization adjuster 10 promptly is as no negative pressure suppression device, avoiding municipal network water supply to produce negative pressure, thereby influence the stable of whole water system.The water inlet end of current stabilization adjuster 10 connects first FlexbleJoint 61, the first maintenance valve 41, backflow preventer 7, second FlexbleJoint 62, dirt separator 5, the second maintenance valve 42, water inlet total valve 3 successively.The other end of water inlet total valve 3 also with successively is connected with pressure meter and intake pressure sensor 2, first drain valve 1, and wherein this intake pressure sensor 2 is connected with electrical control center 11.Backflow preventer 7 is set is when preventing that this preferred embodiment from shutting down, user's pipe network water pressure is higher than the hydraulic pressure of municipal network water supply, causes aqueous reflux in user's pipe network to go into municipal water supply network and pollutes.Dirt separator 5 is to establish for assurance backflow preventer 7 operate as normal, has guaranteed water supply quality.The first maintenance valve 41 and the second maintenance valve 42 are to be provided with for conventional maintenance such as backflow preventer 7, dirt separator 5 and maintenance.Pressure meter and intake pressure sensor 2 be set be for show and sensing water inlet total valve 3 before force value.First drain valve 1 is set is for before equipment being completed put into operation and water supply network maintenance when resuming water supply after cutting off the water, can the contaminated water of the emptying water inlet pipe network segment.
Pump water sucking mouth pressure sensor and pressure meter 8 also are set on current stabilization adjuster 10 in addition, and this pump water sucking mouth pressure sensor is connected with electrical control center 11, and it is for the available force value of pump group in sensing and the actual pipe of demonstration that pump water sucking mouth pressure sensor and pressure meter 8 are set.
One end of water outlet collecting fitting 17 is provided with an air pressure tank 16, and the other end is connection traffic meter 22, second drain valve 20, the 3rd FlexbleJoint 63, water outlet total valve 21 successively.Wherein this air pressure tank 16 is in order to guarantee that system pressure is constant and to reduce water hammer.Flow meter 22 is by detecting each transient flow constantly, and will detect data and send to connected electrical control center 11, realization avoids maximum water supply flow to exceed system's design maximum flow value, to guarantee the water supply security of surrounding area to the control of water supply flow.Second drain valve 20 is set is when guaranteeing equipment scheduling, can make the equipment water supply flow reach the design maximum flow value, for the relevant controlling parameters of determining the normal operation of equipment is given security.Water outlet collecting fitting 17 is provided with outlet pressure sensor and pressure meter 18, and this outlet pressure sensor is connected in electrical control center 11, outlet pressure sensor and pressure meter 18 sensings and demonstration be system's operation setting value.
In Fig. 1, main pump 15, auxilliary pump 14, flow meter 22 and each pressure sensor communicate to connect respectively in electrical control center 11, dotted line is promptly represented the aforementioned communication annexation among Fig. 1, and electrical control center 11 is gathered every water supply data in real time and adjusted with the running status to main pump 15 and auxilliary pump 14.
By above-mentioned detailed description as can be known, the utility model adopts alternative original vertical multi-stage of pump group or single-stage tubing pump in the pipe, because the submersible pump of pump group is fully immersed in the water of fair water sleeves in the pipe, is not afraid of water logging.Gas in the sleeve drained to realize water supply facilities subwoofer operation, therefore comprise that also the utility model of no negative pressure suppression equipment not only can not cause the municipal network water supply negative pressure, it has the advantage of quiet operation what is more important, can not produce noise pollution and influence around work and living environment.
Yet the above only is a preferred embodiment of the present utility model, and unrestricted protection domain of the present utility model, so the equivalence that all utilization the utility model manuals and accompanying drawing content have been done changes, all is included in the protection domain of the present utility model.
