Dynamic, now, check-valves 18 are opened, current stabilization check-valves 10 cut out for compensation, water pump 22 will be started by pressure compensated pump 17 before from steady
The stream water intaking of tank 8 is converted to the pattern after pressure compensated pump 17 starts from the water intaking of stainless steel water tank 14, and in pressure compensated pump
After 17 start, flow control valve 7 also will cut out immediately and cut off tap water water inlet pipe 1 and steady-flow tank 8 will be intake, stainless steel water tank
14 water level begins to decline, when stainless steel water tank 14 water level decreasing to the fixed lower water level point of systemic presupposition and it is following when, water tank
Water inlet electrically-controlled valve 13 opens moisturizing, and when the rate of water make-up of stainless steel water tank 14 is not enough or without moisturizing, the operation of pressure compensated pump 17 will
Cause stainless steel water tank 14 water level continue decline, and drop to the fixed hydropenia water level point of systemic presupposition and it is following when, pressure mend
Repay 17 stoppage protection of pump and report to the police, Water sterilizer 19 is closed, the purpose that pressure compensated pump 17 is arranged in system is for water pump
22 are provided with pressure water source, make water pump 22 no matter fetch water from steady-flow tank 8, the situation of the water intaking of reinforced plastic water container 14 that is also to switch to never to become rusty it is equal
The basic voltage stabilizing of intake pressure can be reached and pressure oscillation is reduced, when detecting distribution main's 11 by water distribution pressure detecting table 12
When water pressure is less than systemic presupposition fixed low voltage value, operating water pump 22 is by stoppage protection and reports to the police, and system is cut off the water, and
Water sterilizer 19 opened when water pump 22 runs, close when water pump 22 is shut down, when being detected by water distribution pressure detecting table 12
To distribution main 11 water pressure it is fixed higher than systemic presupposition when opening pump pressure value, water pump 22 is by automatic and recovers normal and transports
OK；At the same time, rise when the pressure that tap water water inlet pipe 1 is detected by intake pressure detection table 5, and higher than systemic presupposition
Fixed when opening valve pressure value, flow control valve 7 will be opened, and pressure compensated pump 17 is closed, and now current stabilization check-valves 10 are opened, compensated
Check-valves 18 cut out, and water pump 22 will automatically switch to steady-flow tank 8 and fetch water, so repeatedly, realize water pump 22 from steady-flow tank 8 water intaking and
From the mutual switching of the water intaking of stainless steel water tank 14, and tap water will be made full use of to intake when water pump 22 is fetched water from steady-flow tank 8
Original pressure of pipe 1 reaches energy-saving effect, will ensure 1 pressure of tap water water inlet pipe when water pump 22 is fetched water from stainless steel water tank 14
The safety water supply at the continuous water source of the lowest service pressure value fixed less than systemic presupposition, improves reliability of water supply.
Additionally, when 1 pressure of tap water water inlet pipe is sufficient, and being supplied water up to more than 12 hours always by steady-flow tank 8 or surely
Stream tank 8 supplies water an integrated flow when reaching the limit value flow of setting, and system will be forced shutdown flow control valve 7, to switch to
Stainless steel water tank 14 provide water source service position, with ensure the water storage in stainless steel water tank 14 be not because long-time be detained and
Go bad, degenerate, the integrated flow that the steady-flow tank 8 supplies water is carried out by the flow monitoring meter 27 being installed on outfall sewer 23
Determine, and start when opening from flow control valve 7 calculating to flow control valve 7 close when timing terminate.
