The respiratory component of steady flow compensator 3 is internally provided with float shutter (being not shown), when the water of steady flow compensator 3
When position declines, the float shutter in vacuum suppresser 12 declines and air-breathing, prevents seawater water inlet pipe 1 from generating negative pressure；And when steady
When flowing the water inlet of 3 abdomen sky of compensator, vacuum suppresser 12 is exhaled；It is also inevitably miscellaneous in the presence of some in view of the seawater after purified
Matter, the utility model are also provided with sewage draining exit 13 in the bottom of steady flow compensator 3, and the dirt in steady flow compensator 3 can pass through row
Dirty mouth 13 is discharged.
Further, the aqueous reflux in order to prevent in the water supply network in user's building causes in seawater water inlet pipe 1
Pollution, backflow preventer 14, wherein backflow preventer are provided between steady flow compensator 3, water tank 4 and seawater water inlet pipe 1
14, to be detachably connected, when anti-down flow device is not arranged in seawater water inlet pipe 1, then must install backflow preventer 14；If extra large
It is provided with anti-down flow device in water water inlet pipe 1, setting may be selected or is not provided with backflow preventer 14.
The operation principle and process of the utility model is given below：
After water pump pumps to seawater water inlet pipe 1, seawater enters in fresh-water generator 15 seawater first, when seawater is light
Change the concentration of water in device less than the concentration detector 16 after limit value (reaching fresh water standards), being set in fresh-water generator to
Control system 6 sends signal, and control system 6 controls fresh-water generator 15 and opens, and is connected with sea water purifier 16, after desalination
Water vacuum pressure when starting to set the operation of seawater tailored version non-negative pressure water-supply installation after purification is stablized in the sea water purifier 17
The lowest starting pressure of table 7 resets the required highest water pressure of seawater tailored version non-negative pressure water-supply installation service area
Then voltage limiting value is given seawater tailored version non-negative pressure water-supply installation to be powered and is run.
When the pressure of supply water of seawater water inlet pipe 1 is less than service area highest higher than the startup pressure of the pressure vacuum gauge 7
When with the voltage value of water pressure, control system of electric cabinet 6 controls 5 low speed of water pump assembly and slowly starts, then gradual speedup until
Water pump assembly 5 reaches metered flow and pressure and held stationary is run.
When device service area water consumption is reduced, equipment pressure of supply water rises and surmounts equipment pressure of supply water setting value, electricity
Control cabinet control system 6 will reduce system power supply frequency automatically so that 5 rotating speed of water pump assembly reduces, and equipment water yield is reduced；Work as confession
After water pressure drops to proximity device setting pressure of supply water value, constant pressure water supply is carried out；If water pump assembly 5 is in minimum speed operation
No user water in a period of time, the then sleep of water pump assembly 5 are shut down, and to reduce energy consumption, extend 5 service life of water pump assembly；Water
Pump assembly 5 sleep during a small amount of undertaken by water tank 4 with water and system water clock；When water tank 4 does not undertake, power control cabinet control
System 6 processed sends out signal and wakes up the operation of water pump assembly 5.
When seawater water inlet pipe 1 is when carrying out water less than water consumption, the water level line in steady flow compensator 3 can be with the increasing of water consumption
Add and decline, at this point, control system of electric cabinet 6 is by according to the pressure data of the pressure vacuum gauge 7 of reception, using fuzzy control original
The rotating speed of reason control water pump assembly 5 so that water pump assembly 5 slows down from motion tracking, so that the water-in and water-out balance of steady flow compensator 3,
Seawater water inlet pipe is avoided to generate negative pressure because hydraulic pressure overruns decline；Continue to reduce when seawater water inlet pipe 1 carrys out water, steady flow compensator
Water level in 3 continues to decline, and when insufficient pressure, the startup of auxiliary pump 11 is drawn water to 5 water inlet pipe of water pump assembly, directly from water tank 4
It fetches water to partition balance stable-flow compensator 3 from seawater water inlet pipe 1, to protect 1 pressure of seawater water inlet pipe, when seawater water inlet pipe 1
Water continues to reduce, when liquid level gauge 8 detects setting liquid level of the water level decreasing in water tank 4 to liquid level gauge 8, control system 6
Control water pump assembly 5 shuts down effective operation under lower-speed state and seawater water inlet pipe 1 is prevented to generate negative pressure because shutting down suddenly, prolongs
The service life of equipment is grown；Obstruction warning unit 9 is touched simultaneously and sends out alarm signal, and worker is carried out remote by console
Place's operation, solves the emergency cases such as region hydraulic pressure in time.
When seawater water inlet pipe 1, which carrys out water, to be restored to setup pressure value, it is low that control system of electric cabinet 6 controls water pump assembly 5
