Embodiment
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Fig. 1 is a kind of schematic diagram of high-efficiency feedwater equipment of the utility model, as illustrated, of the present utility model a kind of efficient Water work specifically includes:Imported valve 1, filter 2, backflow preventer 3, vacuum suppresser 4, vacuum table 5, steady flow compensator 6, blowoff valve 7, compensator entrance 8, compensator outlet 9, check-valves 10, inlet pressure gauge 11, delivery gauge 12, booster pump I 13, booster pump II 14, valve I 15, valve II 16, check valve I 17, check valve II 18, bypass line 19, high pressure compensation device 20, Compensator port 21, inflation inlet 22, pressure transmitter 23, outlet valve 24, control device 25.
A kind of high-efficiency feedwater equipment, its entrance are connected by imported valve 1 with water supply network, and current pass through the mistake of filter 2 After filter, steady flow compensator 6 is entered by compensator entrance 8 by backflow preventer 3, the top of steady flow compensator 6 presses down equipped with vacuum Device 4 and vacuum table 5 processed, the bottom of steady flow compensator 6 are equipped with blowoff valve 7.Steady flow compensator 6 passes through compensator outlet 9 and supercharging Pump assembly couple, supercharging pump group by booster pump I 13, booster pump II 14, connecting pipeline, inlet pressure gauge 11, delivery gauge 12, Valve and check valve composition.According to the difference of the signal that supercharging pump group delivery gauge 12 feeds back and water work setting pressure signal Value, control device 25 adjust the number of units of booster pump start and stop and the rotating speed of water pump, so as to adjust the output pressure of supercharging pump group, until Untill output pressure reaches the permissible range of setting pressure.Pump group is pressurized so as to which water is sent into user's pipe network according to system requirements.
Supercharging pump group import is connected with steady flow compensator 6, and the moment of control device 25 detects the input and output of water work The start and stop of pressure regulation booster pump and rotating speed, the valve of vacuum suppresser 4 is opened and closed, ensures not produce in steady flow compensator 6 Raw negative pressure, ensures the normal of tap water pipe network pressure.The outlet of supercharging pump group is connected by compensator port 21 with high pressure compensation device 20 Connect, high pressure compensation device is configured with inflation inlet 22 and pressure transmitter 23.Fig. 2 is the schematic diagram of the utility model high pressure compensation device, High pressure compensation device 20 includes high pressure compensation device tank body 201 and diaphragm of rubber 202.Container of the diaphragm of rubber 202 as water, with gas Separation, prevents water from receiving secondary pollution., it is necessary to give the height of high pressure compensation device 20 by inflation inlet 22 before water work dispatches from the factory Gases at high pressure are pre-charged with pressure compensator tank body 201.Signal is fed back to control device 25 by pressure transmitter 23, when high pressure is mended When repaying the pressure in device 20 and being less than permissible working pressure, signal is fed back to centralized control center's prompting supplement pressure demand by controller. The one side of high pressure compensation device 20 stores part system power surplus as energy accumulating device when with water low ebb, with water height Released energy when peak, pressure compensation is carried out to water work;On the other hand flow compensation device is used as, in low discharge water In the case of, it is not necessary to start booster pump, by high pressure compensation device 20 directly to user's pipe network water supply, save water work energy Consumption.Supercharging pump group is made up of booster pump I 13 and booster pump II 14, and wherein the metered flow of booster pump I 13 is the volume of booster pump II 14 / 5th of constant flow, when water work low discharge is run, start booster pump I 13, while to user's pipe network water supply, supercharging The water filling into the diaphragm of rubber 202 of high pressure compensation device 20 simultaneously of pump I 13, diaphragm of rubber 202 expand, high pressure compensation device tank body 201 In pressure rise until the pressure in high pressure compensation device tank body 201 and supercharging pump group outlet pressure reach balance;Big flow is transported During row, start booster pump II 14, water use peak, two booster pump oeprations at full load simultaneously.When rate of discharge is more than inlet flow rate When, the liquid level of steady flow compensator 6 declines, and drops to certain low water level position, and booster pump will be delayed and shut down, after water level recovers, water Pump resumes operation automatically.
When the ductwork pressure p1 of running water is less than the setting pressure p that user needs, control device automatically controls supercharging The number of units of pump start and stop and the rotating speed of booster pump, until water work output pressure p2=p, as p2 > p, booster pump runs slowly, As p2 < p, booster pump Accelerating running.As p2=p, water work carries out automatically useless water detection, then autostop, As p2 < p, water pump resumes operation automatically.When the setting pressure p of needs is less than inlet pressure p1, system does not start, by city Political affairs water supply network is by bypass line 19 directly to user's pipe network water supply.
When water consumption increase causes city planting ductwork and the connection place pressure decline of steady flow compensator 6, the shape in steady flow compensator 6 Into negative pressure, the signal that control device feeds back according to vacuum table 5 opens the air intake valve of vacuum suppresser 4, and air is mended into current stabilization Repay device 6, the pressure in steady flow compensator 6 is identical with atmospheric pressure, and negative pressure is eliminated.When water level decreasing is to setting value, liquid level control Control signal is passed to control device 25 and controls supercharging pump group to be stopped by device processed, and user cuts off the water.When user's water consumption reduces When, water supply network gives the moisturizing of steady flow compensator 6, and wherein water level rises, and gas is discharged from vacuum suppresser 4, and pressure recovers normal Afterwards, pump group automatic start again is pressurized, is resumed water supply.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit Determine the scope of protection of the utility model, it is all within the spirit and principles of the utility model, any modification for being made, equally replace Change, improve, should be included within the scope of protection of the utility model.
