Detailed description of the invention
Do further structure below in conjunction with accompanying drawing to the utility model to describe:
As shown in Figure 1, the utility model comprises inwall welding stainless steel water tank 1, pump group 9, intelligent control module 3, the visual module of digital remote, the water inlet pipe of inwall welding stainless steel water tank 1 is connected with city planting ductwork 14, the outlet pipe of inwall welding stainless steel water tank 1 is connected with the water inlet collecting fitting 4 of pump group 9, the water outlet collecting fitting 7 of pump group 9 is connected with user's pipe network, the water inlet pipe of inwall welding stainless steel water tank 1 is connected with stainless steel steady-flow tank 10 by Intelligent Switching Device 13, stainless steel steady-flow tank 10 is provided with pressure sensor 12 and vacuum suppresser 11, the water outlet collecting fitting 7 of pump group 9 is provided with successively the pressure sensor 8 be connected with intelligent control module 3, butterfly valve 2, flap valve 5, pump group 9 is composed in parallel by multiple water pump, and each water pump of pump group 9 is all connected with intelligent control module 3, intelligent control module 3 is connected with the visual module by signal of digital remote.
The water inlet pipe of inwall welding stainless steel water tank 1 and city planting ductwork 14 junction are provided with and intake main valve 15 without negative pressure; The outlet pipe of inwall welding stainless steel water tank is provided with butterfly valve 6;
Described pump group 9 is composed in parallel by the centrifugal pump of four different capacities;
Anti-water quality deterioration device can be provided with in described inwall welding stainless steel water tank.
Intelligent control module forms primarily of PLC, analog quantity/digital quantity expansion module, ethernet communication module, frequency converter and instrument and meter group; It, by judging for water environment and after data acquisition, do not need manual control, both intelligence can switch way of supplying water targetedly.Way of supplying water comprises: 1, constant pressure water supply; 2, supply water without negative pressure (pipe network superimposed); 3, frequency-changing pressure stabilizing+single entry composite frequency conversion technology supplies water; 4, supply water without negative pressure (pipe network superimposed)+single entry composite frequency conversion technology.Safety, the reliability of assure feed water is come with this.
These four kinds of mode of operations are specifically such:
Frequency-changing pressure stabilizing, refer to and pipe network superimposed pattern cannot be used to supply water when the pressure of supply water in public supply mains is less than the pressure of supply water needed for pipe network superimposed pattern, at this moment water pump is used to keep water to enter access user pipe network with constant voltage, in the process keeping constant voltage, according to the size of user's pipe network water requirement, variable frequency control is carried out to motor, save electric energy.
Without negative pressure (pipe network superimposed), refer to and use pipe network superimposed pattern to supply water when the pressure of supply water in public supply mains is more than or equal to the pressure of supply water needed for pipe network superimposed pattern.
Frequency-changing pressure stabilizing+single entry composite frequency conversion technology, refers to when adopting constant pressure water supply, according to environment for use, adopts single entry composite frequency conversion technology.
Without negative pressure (pipe network superimposed)+single entry composite frequency conversion technology, referring to when adopting pipe network superimposed water supply, according to environment for use, adopting single entry composite frequency conversion technology.
Wherein single entry composite frequency conversion technology refers to and carries out switching frequency conversion to the motor of multiple stage different capacity.Citing is explained: the water supply flow of certain community is 30m
3/ h, Yang Cheng H=58m, H=7.5KW, the using and the reserved are selected in traditional microcomputer feedwater, and in any water supply period, be all that 7.5KW motor is working, just frequency is different.And adopt single entry composite frequency conversion technology, refer to and prepare a little pump again beyond the motor of 7.5KW, the flow of such as this little pump is 12m
3/ h, Yang Cheng are H=58m, and power is 3KW.When supplying water, as long as output (12m in the flow that little pump can bear
3/ h), then operated by little pump frequency conversion, if exceed the flow that little pump can bear just be automatically converted to the running of large pump frequency conversion, little pump stops.If use traffic drops to below the flow that little pump can bear again, just convert again the running of little pump frequency conversion to.
It should be noted that, if this pumping plant only configures a water pump or the identical water pump of several power, so then cannot adopt single entry composite frequency conversion technology.
The pad of inwall welding stainless steel water tank 1 outside casing, its inwall solderless contact.
Compared with traditional non-negative pressure water-supply installation, the utility model will be more flexible in water supplying machine group configuration; Such as, the water supply requirement of certain community is flow Q=60m3/h, Yang Cheng H=50M, H=15kw, and traditional microcomputer feedwater selection three crew qiting are dual-purpose one standby, are supplying water the period arbitrarily, be all 15KW motor in work, just frequency different and with.If but have employed CLYH single entry composite frequency conversion technology, just could select the pump group 9 of three different sizes, according to upper example, could be by crew qiting:
Q=30m3/h, H=50M, N=5.5kw(mono-)
Q=50m3/h, H=52M, N=7.5kw(mono-)
Q=70m3/h, H=57M, N=11kw(mono-)
Q=90m3/h, H=57M, N=15kw(are for subsequent use)
Several units can according to water supply volume independent assortment switching above, equipment is by user's setting and the detection to flow, automatically can drop in morning peak the unit that flow is 70 tons, the unit that flow is 50 tons is dropped on noon peak, evening peak drops into 90 tons and 70 tons of units, dropping into 30 units night, by that analogy, is that whole pump house is all operated in high-effect district in all water supply periods.The utilization of this control flow water system, fullys meet the object of energy saving, is best About Energy Saving Method.Can combine with constant pressure water supply mode, non-negative pressure method of water supply mode respectively, substantially increase the high efficiency of original water supply, than existing any one supply equipment energy-conservation about 40%.
The utility model also has following advantage:
1. modularized design: complete equipment is modularized design thinking, simple and convenient and reserved expansion interface is installed, can upgrade to equipment at any time according to user's request, the timely application making it need not change complete equipment just can to realize new technology, New function, thus save a large amount of equipment later stage update costs;
2. multi-ensuring is for water stability: when pipe network water supply is not enough or pipe network is cut off the water, system automatically switches to cistern water supply, when pipe network Recovery and rebuild, system recovers normal use automatically, when meeting with power failure, equipment relies on tap water pipe network pressure itself can maintain the water supply of certain hour.
The utility model is not limited to above-mentioned preferred embodiment, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
