Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement
Example is for illustrating the present invention, but is not limited to the scope of the present invention.
As shown in figure 1, the one outlet of elevated tank 3 is connected with day miscellaneous water end by flow transducer 25；It is high-order
Another outlet of water tank 3 is connected with industrial water end by being pressurized pump group；The entrance of elevated tank 3 is by controlling valve 4 12
It is connected with water level promoting pump group, water level promoting pump group is arranged in middle pond, for the middle water in middle pond is pumped into high-order water
Case 3 or water in directly providing for industrial water end.The outlet of water level promoting pump group passes through a branch road and is pressurized going out for pump group
Mouth pipeline connection, and the branch road is provided with control valve 1；The export pipeline of supercharging pump group is converged with the branch road of water level promoting pump group
It is connected with industrial water end again afterwards, and the pool side pipeline is provided with flow transducer 1 and pressure transducer 1.Increase
Press pump group includes at least two and the water pump 1 for connecting together, and water level promoting pump group includes at least two and the water for connecting together
Check-valves are respectively connected with the export pipeline of pump 2 13, every water pump 1 or water pump 2 13.Day miscellaneous water end is divided into a plurality of
Road, is equipped with control valve 26 on every branch road.Industrial water end is also classified into a plurality of branch road, and control is respectively connected with every branch road
Valve processed 3 11 and pressurized tank 10, are equipped with pressure transducer two and relief valve on pressurized tank 10, pressure transducer two is propped up with each
Control valve 3 11 on road connects.Above-mentioned liquidometer 2, water pump 1, water pump 2 13, control valve 1, control valve 26, control valve
3 11, control valve 4 12, flow transducer 1, flow transducer 25 and pressure transducer 1 to connect with master control cabinet 1
Connect.Heavy line in Fig. 1 represents system pipeline, and chain-dotted line represents control circuit.
Operation principle：
Control valve 4 12 is opened by master control cabinet 1, and starts water pump 2 13, start middle water to be pumped in elevated tank 3,
The liquid level that can be measured according to liquidometer 2 of number of units that water pump 2 13 is opened and useful water end branch middle water usage amount
To determine.When day miscellaneous water end needs to use water, the control valve 26 of respective branch is opened, you can realize supplying water.Master control cabinet 1
The aperture of valve 26 is controlled by reading the real time data that measures of flow transducer 25, so as to realize Flow-rate adjustment.
In the needs offer of industrial water end during water, start a water pump 1 first, the middle water after supercharging enters production use
The respective branch of water end, can use Jing after control valve 3 11 and pressurized tank 10 are adjusted.Master control cabinet 1 is passed by reading flow
Whether the measurement data of sensor 1 and pressure transducer 1 is enough to determine pressure, if insufficient pressure, that is, starts second water
Pump 1.If all water pumps 1 still cannot meet the demand of production end water after all starting, control valve one is opened in control
9, and start a water pump 2 13, the middle water in middle pond is pumped directly into into industrial water end, to increase industrial water end
Hold the middle discharge and pressure of each branch road；If cannot still meet use demand with the pressure or flow of water end branch, under startup
One water pump 2 13, until meeting the water demand of branch road.
Due to the pressure and traffic demand of each branch road centering water in industrial water end it is different, valve 3 11 and pressurized tank
10 regulation shunting actions, in pressurized tank 10, the gas volume of certain mass is inversely proportional to pressure, and water is produced into pressurized tank 10
Air pressure, the control valve 3 11 and pressurized tank 10 on branch road measure the middle water pressure in branch road in real time by pressure transducer two, and
Be adjusted according to setup parameter, in certain pressure, each branch road parameters reach balance, each water terminal pressure is used when meeting
Frequency-conversionbooster booster water pump group fall-back during requirement with flow.
Domestic water end is divided into a plurality of branch road, including toilet flushing, greening, cleaning ground etc. are not directly and human contact
Occupation mode, these are relatively low with the requirement of water end centering water pressure, only need to can be met using will by elevated tank 3
Ask, therefore, flow transducer 25 is only provided with the main pipe rail of domestic water end, to realize adjusting the aperture of control valve 26
Purpose.
Industrial water end is also classified into a plurality of branch road, including between the dehydration machine room backwashing water of sewage treatment plant, pretreatment
Backwashing water, advanced treating backwashing water and make up a prescription the/branch road such as disinfection room power water, the pressure of these branch road centering water and
Flow has different requirements, therefore each branch road is separately installed with control valve 3 11 and pressurized tank 10, and pressurized tank 10 is according to setting ginseng
Number, and the aperture of control valve 3 11 is adjusted, with the purpose for realizing being adjusted the middle discharge and pressure of respective place branch road.
As can be seen from the above embodiments, it is of the invention by each end supercharging equipment is focused on water main road, and
The mode of control valve 3 11 and pressurized tank 10 is set on the branch road for needing to adjust pressure, the use to different use requirements is realized
The purpose supplied water simultaneously by water end.When the pressure or flow that are pressurized pump group offer cannot meet the demand with water end,
Still can be supplemented to pressure or flow are carried out with water end by water level promoting pump group, to ensure use demand.Booster water pump
Negligible amounts, after installation, floor space is less, and maintenance capacity is also smaller, and installation cost is low.Respectively with the middle current of water end branch
Amount and pressure flexibly can be controlled, and can meet different water demands, and system availability is stronger.All water pumps, sensor and control
Valve processed etc. all passes through master control cabinet 1 and realizes control, and the dependence of system on human power is less, saves substantial amounts of labour force.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement and replacement can also be made, these improve and replace
Also should be regarded as protection scope of the present invention.
