The carrying out practically pattern of the supply equipment that the utility model is related to is as follows：
1：Night packing stage：The pressure of supply water under low discharge state is ensured by air pressure tank 17.
2：Normally laminate the water supply stage：When pipeline pressure of supply water declines, i.e., the 3rd pressure sensor 19 reaches default opening
During pump pressure, initially ride along the 1# main pump variable frequency water supplies in three water pumps on water supply branch road, hereafter 12 3# main pumps all at
The water supply stage is laminated in normal, frequency-conversion control cabinet is carried out by the data that the 3rd pressure sensor 19 is gathered to laminating water supply branch road
Constant pressure frequency conversion is controlled, plus pump subtracts pump impeller and changes, alternative variable-frequency.
3：The municipal water pressure deficiency stage：Pressure switching is set by monitoring the second pressure sensor 12 of municipal water pressure to protect
Shield value, when municipal water pressure drops to this protection value, 12 3# main pumps shut down, water pump 14 starts, by laminate water supply be transformed into from
Drawn water in water tank 10, that is, laminate water supply and be converted to the box constant pressure water supply pattern of light water.
4：Municipal water pressure Restoration stage：When municipal water pressure returns to protection value, 12 3# main pumps, that is, laminate water supply branch road
On three starting mode of pump, water pump 14 shuts down, and is switched to by drawing water from water tank and laminates the box frequency-changing pressure stabilizing of water supply, i.e. light water and supply

5：Water tank self-cleaning explanation：Regularly, 24 hours (adjustable), timing opens magnetic valve to Water in Water Tank to set-up of control system
Flushed, it is unhygienic that stagnant water occurs in waterproof, 72 hours (adjustable), being regularly switched to water tank by laminating water supply pattern draws water mould
Formula, waterproof stagnant water overlong time.
The control operational mode of the frequency-conversion control cabinet in the utility model is as follows：
When the value of first pressure sensor 3 is when allowing in the range of regulation, the 3rd pressure sensor 19 exports equipment
Pressure feedback is compared the actual value of the 3rd pressure sensor 19 and preset value to frequency-changing control system, Intelligent control cabinet
Compared with, when less than preset value, then number pump of varying frequency starting is overlapped on the basis of the pressure of second pressure sensor 12,
Number pump of frequency conversion starts raising speed from 0HZ, and system is two standby with one, when a variable frequency pump rises most 50HZ, if the 3rd pressure is passed
When the value of sensor 19 is also less than preset value, through time delay, then a variable frequency pump switchs to general pump automatically, and No. two are changed into variable frequency pump；
When the actual value of the 3rd pressure sensor 19 is equal to preset value, through time delay, variable frequency pump subtracts frequency operation, when reducing to low-limit frequency
When, general pump can be automatically stopped, using variable frequency pump automatic water-supply.
The utility model and embodiments thereof are described above, the description does not have restricted, shown in accompanying drawing
