Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
Fig. 1 is overall structure schematic diagram of the present utility model, as shown in Figure 1, the high rise building water supply equipment that this utility model provides includes: at least one Tai Di district booster pump and at least Yi Taigao district booster pump, at least one Tai Di district booster pump forms low district's supercharging unit, and at least Yi Taigao district booster pump forms high district's supercharging unit；When low district booster pump is more than one, low district booster pumps connected in parallel, when high district booster pump is more than one, wherein the inlet connection of Yi Taigao district booster pump is divided into two-way, check-valves 6 of leading up to connects with water inlet manifold 9, flow-limiting valve 2 of separately leading up to connects with the outfall sewer 10 of low district's supercharging unit, and remaining high district booster pump (only illustrating with Yi Taigao district booster pump 4 in Fig. 1) is arranged between water inlet manifold 9 and high district service water outlet.Between on pipeline between water inlet manifold 9 and remaining high district booster pump, Pressure gauge 7 and pressure transducer 8 are installed.Check-valves 6, maintenance valve 5 and Pressure gauge 7 and pressure transducer 8 are installed on the pipeline between high district booster pump and high district service water outlet.Check-valves 6, maintenance valve 5 and Pressure gauge 7 and pressure transducer 8 are installed on the pipeline between low district booster pump and low district service water outlet.
In concrete implementation process, the control valve 2 in this utility model is waterpower flow-limiting valve or electrically-controlled valve.
When high and low district low discharge supplies water, only need to start a Tai Di district pump 1, while this Beng Weidi district low discharge supplies water, the prime supercharging (part for low district pump 1 flow is passed through flow flow-limiting valve 2 and flowed to the entrance of high district pump 3) also supplied water as high district low discharge, the water flow of such low district pump 1 is height two district's flow sums, owing to extending working flow, this way significantly improves.As for the low discharge pressure of supply water in high district, in low district pressure-based up-conversion, Ze Yougao district pump 3 runs how much difference is how many mends, finally meets high district water requirements.
The running that above-mentioned low discharge supplies water, the lowest district pump discharge expansion efficiency is substantially improved, high district pump also can make efficiency be promoted because of frequency reducing brownout operation, the data such as provided according to Grandfos Selection Software, to Grandfos CR20-8 pump, when its working flow is equal to metered flow 25%, during 100 meters of constant-pressure operations, the efficiency of pump is 42.%, pump motor aggregate efficiency 36%；
During 60 meters of constant-pressure operations, the efficiency of pump is promoted to 48.4%, and pump motor aggregate efficiency is promoted to 42.7%；During 30 meters of constant-pressure operations, the efficiency of pump is promoted to 56.8%, pump motor aggregate efficiency is promoted to 52.5%.
When high and low district, customer flow increases to a certain degree, rule is greater than the 50% of high low area booster pump metered flow, or when being enough to make high and low district booster pump enter efficient district, flow-limiting valve 2 is automatically switched off, the lowest district pump 1 only serves respective subregion with the water supply flow of high district pump 3, and the inlet water source of the highest district pump 3 automatically switches to equipment water inlet manifold.In order to each pump uniformly uses, it is possible to control original operating high and low district pump and shut down, use other high low area pump instead and put into operation.
In sum, aforesaid low discharge Energy Saving Method, the independent operating of high low area supercharging unit when not affecting big flow, and it is switched to low discharge Energy Saving Method from big flow independent operating mode, it is clear that also it is oneself but simple.
Flow-limiting valve 2 shown in Fig. 1 can use the flow-limiting valve of hydro powered, when high district pump 3 low discharge runs, flow-limiting valve is in opening state, Lai Zhiyudi district, pump 3 water source, high district outfall sewer, when high district pump 3 water flow is higher than flow-limiting valve rated value, flow-limiting valve is automatically switched off, and the inlet water source of high district pump 3 automatically switches to equipment water inlet manifold, flow-limiting valve operation principle: velocity pressure ratio when mainly utilizing initial tension of spring and medium to run, controls the keying of valve internal actions element.
Equipment shown in Fig. 1, high low area supercharging unit can be with supporting more booster pump (two, the most each picture in figure) as required, the Controlling principle realizing energy-saving run is: when high and low district low discharge supplies water, rule is less than the 50% of high low area booster pump metered flow, and equipment is run by aforementioned low discharge power save mode.
When high and low district, customer flow increases to a certain degree, rule is greater than the 50% of high low area booster pump metered flow, or when being enough to make high and low district booster pump enter efficient district, flow flow-limiting valve 2 is automatically switched off, at this moment high low area supercharging unit respectively runs a pump, and its water supply flow only serves respective subregion.
When high and low district, customer flow increases further, during more than high low area booster pump metered flow, need to add parallel connection of pumps to supply water, typically will not synchronize due to high low area customer flow to increase equally, it is possible to be introduced back into aforesaid Energy Saving Method: start high district pump 3 with low district's supercharging unit outlet header as water source, supply water for high district and partial discharge is provided, no matter how high low area flow changes, adding the control scheduling of pump, assignment of traffic should be made reasonable, it is principle that all each pumps are in efficient district.
Equipment shown in Fig. 1, flow-limiting valve 2 is for the water source switching of high district pump 3, it is possible to uses electromagnetic valve, electrodynamic valve etc. instead and does water source switching.The water source switching of electric three passes ball valve Zuo Gao district pump 3 can also be used.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications; in the range of these changes and improvements both fall within claimed this utility model, this utility model claims scope and is defined by appending claims and equivalent thereof.
