Description
Technical field
The utility model relates to a kind of nothing and inhales journey, no negative pressure intelligent water supply equipment.
Background technology
At present, the nothing that the water supply user uses is inhaled journey, non-negative pressure water-supply installation, by the computer transduce switch board, and compositions such as steady flow compensator (afterflow accumulator) vacuum suppresser, city planting ductwork, teletransmission pressure meter, pump group, valve.During the equipment operation, the steady flow compensator and the vacuum suppresser that are connected on the city planting ductwork provide the discharge that needs for the pump group.Equipment self has anhydrous shutdown, and kinds of protect functions such as water start are arranged, and is the new product of second pressure water supply.But in equipment when work, be in the constant pressure water supply state all the time, after the water use peak, and the frequency conversion work always of pump group, power savings is only about 20%, and is energy-conservation undesirable.How both having guaranteed that water system pressure was constant when user's water, the pump group is in resting state in the time of guaranteeing user's low discharge water again, energy-conservation idealized, is puzzlement user's a difficult problem always.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of running water pipe that is directly connected to and carries out the nothing suction journey of pressurizing feedwater, no negative pressure intelligent water supply equipment on the net, in this supply equipment constant-pressure operation after the water use peak, system water supply had both reached constant voltage, again can be without the primer pump group when user's low discharge water.
For solving the problems of the technologies described above, the utility model comprises the flow compensator that is serially connected on the water supply pipe, between flow compensator and user pipe, be parallel with variable frequency pump group pipeline and bypass line by water supply line, the variable frequency pump group is connected with the computer transduce switch board through signal control line, its design feature is to be provided with the teletransmission pressure sensor on water supply line, vacuum suppresser and fluid level controller are installed on the flow compensator, also be provided with the low discharge water receiver on the water supply line, on the low discharge water receiver flow control valve is installed, fluid level controller, teletransmission pressure sensor and flow control valve are connected with the computer transduce switch board through signal control line.
As to improvement of the present utility model, described variable frequency pump group pipeline is the parallel two-tube road.
As to further improvement of the utility model, on the water supply pipe of flow compensator front end and water supply line, the anti counter-flowing controller is installed.
After adopting said structure, owing on water supply pipe, be serially connected with flow compensator, between flow compensator and user pipe, be parallel with variable frequency pump group pipeline and bypass line by water supply line, on water supply line, also be provided with low discharge water receiver by switch board control, in this supply equipment constant-pressure operation after the water use peak, system water supply had both reached constant voltage, again can be without the primer pump group when user's low discharge water, by the low discharge water receiver user is supplied water, and when user's water system needs big flow to supply water, the computer transduce control system is waken supply equipment automatically up and is started, the variable frequency pump group is in big flow constant pressure water supply state again, guarantee the peak water, the unfavorable difficult problem of electricity saving and energy saving when having solved the non-negative pressure water-supply installation constant pressure water supply is brought up to more than 80% by original electricity saving and energy saving about 20%.Bypass pipe is set, can when equipment has a power failure, supplies water to the user by the former pressure in the tap water pipe network.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
With reference to accompanying drawing; this nothing is inhaled journey, no negative pressure intelligent water supply equipment comprises the flow compensator 2 that is serially connected on the water supply pipe; this flow compensator 2 is a stainless steel tank body; on the water supply pipe 9 of flow compensator 2 front ends anti counter-flowing controller 11 and gate valve are installed; between flow compensator 2 and user pipe 12, be parallel with variable frequency pump group pipeline and bypass line by water supply line 10; this variable frequency pump group pipeline is the parallel two-tube road; when breaking down shutdown for one group; then start another group and work on, or the alternation of two groups of variable frequency pump groups.Variable frequency pump group 7 is connected with computer transduce switch board 1 through signal control line, be serially connected with flap valve and gate valve on the pipeline at variable frequency pump group 7 places, be serially connected with flap valve 8 on the pipeline at bypass pipe place, on the water supply line 10 of flow compensator 2 rear ends, be serially connected with gate valve 6 and anti counter-flowing controller 11.It is the aqueous reflux that prevents in the user pipe of water pump shutdown back that flap valve is set, and gate valve is set is convenient to equipment and pipeline maintenance, and bypass pipe is set can be supplied water to the user by the former pressure in the tap water pipe network when equipment has a power failure.On water supply line 10, be provided with teletransmission pressure sensor 3, vacuum suppresser 5 and fluid level controller 4 are installed on flow compensator 6, flow compensator 6 bottoms are provided with sewage draining exit 15, on water supply line 10, also be provided with low discharge water receiver 13, flow control valve 14 is installed on the low discharge water receiver 13, and fluid level controller 4, teletransmission pressure sensor 3 and flow control valve 14 are connected with computer transduce switch board 1 through signal control line.This supply equipment starts Multivariable Fuzzy control and intelligent management system by computer transduce switch board 1, the constant pressure water supply signal behind the water use peak (providing) by teletransmission pressure meter 3, automatically switch to primary flow signal, variable frequency pump group 7 supplies water according to low discharge and touches formula water supply.When user's water system reached setting value (no flow), the variable frequency pump group was according to the control instruction auto sleep.At this moment, low discharge water receiver 13 discharges the chresard of deposit, and user's low discharge water keeps whole water system constant pressure water supply all the time during compensation supply equipment resting state.When user's water system needed big flow to supply water, the computer transduce control system was waken supply equipment automatically up and is started, and variable frequency pump group 7 is in big flow constant pressure water supply state again, guarantees the peak water.The unfavorable difficult problem of electricity saving and energy saving when this equipment has solved the non-negative pressure water-supply installation constant pressure water supply is brought up to more than 80% by original electricity saving and energy saving about 20%.
