Description
Technical field
The utility model is related to new full frequency-changing pressure stabilizing water work, belongs to non-negative pressure water-supply installation field.
Background technology
Existing non-negative pressure water-supply installation, as water source, takes full advantage of the original pressure of city planting ductwork using tap water pipe network
Power, forms closed continuous relay supercharging way of supplying water, but the existing water pump assembly without negative pressure equipment is with certain rotating speed
Running always, do not possessing full frequency conversion function, not only waste the energy, also reducing the service life of water pump assembly.
The content of the invention
Technical problem to be solved in the utility model is：New full frequency-changing pressure stabilizing water work is provided, it is solved
The problem of existing water pump assembly without negative pressure equipment does not possess full frequency conversion.
Technical problem to be solved in the utility model takes following technical scheme to realize：
New full frequency-changing pressure stabilizing water work, including steady flow compensator, water inlet manifold, water pump and outfall sewer are described steady
Stream compensator top offers water inlet and vacuum suppresser, and bottom offers delivery port, the turnover house steward by pipeline with
Three branch pipe(tube)s, three branch pipe(tube) tops and the water is arranged side by side on the delivery port connection of steady flow compensator bottom, water inlet manifold
Pump is connected, and the water pump pipe is connected by pipeline with outfall sewer, and the outfall sewer passes through pipeline communication with water inlet manifold.
As preferred embodiment, wafer type butterfly is disposed with three branch pipe(tube)s that the water inlet manifold is connected with water pump
Valve, rubber soft joint and Wafer Check Valves.
As preferred embodiment, Wafer Check Valves, rubber are disposed with the pipeline that the water pump is connected with outfall sewer
Glue connecting hose and wafer type butterfly valve.
The beneficial effects of the utility model are：By individually matching somebody with somebody a frequency converter to every water pump, when ductwork pressure is higher than
When setting pressure, frequency converter reduces output frequency automatically, and pump rotary speed slows down, and water yield is reduced, when ductwork pressure is less than setting
Pressure when, then automatic increase output frequency, pump rotary speed increase, water yield increase, by setting Wafer Check Valves, effectively
Prevent from flowing backwards, in case impact water pump vane, by setting rubber soft joint, can absorb the vibrations of water pump generation, facilitate pipeline
Connection, prevents pipeline to be damaged, by setting wafer type butterfly valve, plays a part of cutting off and damming.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model；
In figure：Steady flow compensator 1, water inlet manifold 2, water pump 3, outfall sewer 4, water inlet 5, vacuum suppresser 6, delivery port
7, wafer type butterfly valve 8, rubber soft joint 9, Wafer Check Valves 10, branch pipe(tube) 31.
Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1-2, new full frequency-changing pressure stabilizing water work, including steady flow compensator 1, water inlet manifold 2, the and of water pump 3
Outfall sewer 4, the top of steady flow compensator 1 offers water inlet 5 and vacuum suppresser 6, and bottom offers delivery port 7, and turnover is total
Pipe 2 is connected by pipeline with the bottom delivery port 7 of steady flow compensator 1, and three branch pipe(tube)s 31, three are arranged side by side on water inlet manifold 2
The top of branch pipe(tube) 31 is connected with water pump 3, and the pipe of water pump 3 is connected by pipeline with outfall sewer 4, and outfall sewer 4 leads to water inlet manifold 2
Piping is connected.
Wafer type butterfly valve 8, rubber soft joint 9 are disposed with three branch pipe(tube)s 31 that water inlet manifold 2 is connected with water pump 3
Wafer Check Valves 10, rubber are disposed with the pipeline being connected with Wafer Check Valves 10, water pump 3 with outfall sewer 4 soft
Joint 9 and wafer type butterfly valve 8.
During normal water supply, when water source enters in steady flow compensator 1, vacuum suppresser 6 is started working, and adjusts chamber air
Content, makes it be full of water；When water shortage, the water level decreasing in steady flow compensator 1, at this moment vacuum suppresser 6 start with air
To adjust the pressure of intracavitary, water supply is set to keep voltage stabilizing output.
During normal water supply, the situation of change of water consumption in the real-time test chamber of negative-pressure detection device in steady flow compensator 1, surely
Be full of in stream compensator 1 after water to the water inlet end of water pump 3 and send water, supplied water when being more than demand, stored in steady flow compensator 1 after full water in case
Delay to fill during next water shortage and use, vacuum suppresser 6 is closed, and pressure returns to tap water pipe network pressure in steady flow compensator 1, at this moment
Output pressure is the difference with water pressure and ductwork pressure so that water pump 3 is run in energy-saving and frequency-variable state, during insufficient water, surely
Flow retaining in compensator 1 to decline, vacuum suppresser 6 is automatically opened up, filter entrance is passed the gas through, so as to eliminate negative pressure shape
Into when water level decreasing to safety level in steady flow compensator 1, negative-pressure detection device is sent under signal, the safe stopping of water pump 3, is supplied
When water is normal, stored in steady flow compensator 1 after full water, vacuum suppresser 6 is closed automatically, prevents overflow.
Every water pump 3 is individually with a frequency converter, and when normally feeding water, water pump 3 operates in low-voltage variable frequency state, passes through PID
The control pressurer system moment monitors ductwork pressure, carries out computing to the pressure sensor value of feedback on pipe network and setting value and compares
Calculate, when ductwork pressure is higher than setting pressure, frequency converter reduces output frequency automatically, and the spin down of water pump 3, water yield subtracts
It is few, it is when pressure of the ductwork pressure less than setting, then automatic to increase output frequency, the increase of the rotating speed of water pump 3, water yield increase.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within claimed sheet
In the range of utility model.Scope is claimed by appended claims and its equivalent thereof in the utility model.
