Background technology: in the water system design process, when the water yield, the hydraulic pressure of outdoor water supply pipe net can not satisfy the water yield of indoor pipe network, when hydraulic pressure requires, thereby the secondary pressurized equipment all need be set to once coming water to promote to satisfy the demand of user's water.
The supply equipment of main second pressurization in the market mainly is to adopt frequency-changing water supply device and non-negative pressure water-supply installation; And can match according to concrete confession, the need condition of project; Yet in actual application; Still there is more problem and shortage part in above equipment; Because the set vacuum tank internal pressure of the pressurized equipment port of export is merely the required pressure of user's least favorable water distribution point (both total head pressure behind the pump), can know that through certain calculating existing second pressure water supply equipment: effective compensation water yield that the low discharge pressure holding function is provided is less; Supply water the period at low discharge, the water pump start and stop are frequent, and particularly night, this phenomenon is comparatively obvious, influence equipment water pump application life; Voltage stabilizing function is not enough, and discharge pressure changes greatly.
Summary of the invention
In view of this; Main purpose of the present invention is to provide a kind of non-negative pressure water-supply installation with long-time voltage stabilizing compensation ability; It can automatically adjust according to the supply working conditions change of city planting ductwork and the changes in demand of user's pipe network; All the time maintain under the prerequisite more than the lowest service value at the protection municipal ductwork pressure; All can guarantee the requirement of user side to the water yield and hydraulic pressure in water supply flow peak period and water supply flow low-valley interval, normal water supply can be guaranteed residual quantity compensation and the flow pressurize of relative long period simultaneously.
In order to achieve the above object; Technical scheme of the present invention is achieved in that a kind of three pot type voltage stabilizings compensation non-negative pressure water-supply installation; Include constant voltage compensating tank, residual quantity compensating tank, variable frequency pump and bidirectional compensating device, the water inlet end of said constant voltage compensating tank is connected with city planting ductwork, and the residual quantity compensating tank links to each other with the bidirectional compensating device; The water side of constant voltage compensating tank links to each other with the bidirectional compensating device with the variable frequency pump input; Comprise low discharge compensating tank and supercharging variable frequency pump, said low discharge compensating tank is connected with the bidirectional compensating device through the supercharging variable frequency pump, and said low discharge compensating tank links to each other with the residual quantity compensating tank through tube connector.
Said bidirectional compensating device is connected with all families pipe network with the water side of variable frequency pump.
Be provided with between said constant voltage compensating tank and the city planting ductwork and have or not vacuum flow amount controller and pressure sensor.
The top of said residual quantity compensating tank and low discharge compensating tank is respectively arranged with energy storage device.
Beneficial effect after the employing technique scheme is: a kind of three pot type voltage stabilizings compensation non-negative pressure water-supply installation; Through the present technique scheme; Traditional secondary pressurization supply equipment is improved; Increased the low discharge compensating tank, solved in the traditional secondary pressurization supply equipment, effective compensation water yield that the low discharge pressure holding function is provided is less; The water pump start and stop are frequent; Voltage stabilizing function is not enough, and discharge pressure changes problem greatly, makes water system move safety and stability, energy-efficient more.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Among the figure, 1 city planting ductwork, 2 tube connectors, 3 no vacuum flow amount controllers, 4 pressure sensors, 5 energy storage devices, 6 user's pipe networks, 7 constant voltage compensating tanks, 8 residual quantity compensating tanks, 9 low discharge compensating tanks, 10 variable frequency pumps, 11 bidirectional compensating devices, 12 supercharging variable frequency pumps.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention and technology contents are described further.
As shown in Figure 1; The three pot type voltage stabilizings compensation non-negative pressure water-supply installation that the present invention relates to; Include constant voltage compensating tank 7, residual quantity compensating tank 8, variable frequency pump 10 and bidirectional compensating device 11, the water inlet end of said constant voltage compensating tank 7 is connected with city planting ductwork 1, and residual quantity compensating tank 8 links to each other with bidirectional compensating device 11; The water side of constant voltage compensating tank 7 links to each other with bidirectional compensating device 11 with variable frequency pump 10 inputs; Comprise low discharge compensating tank 9 and supercharging variable frequency pump 12, said low discharge compensating tank 9 is connected with bidirectional compensating device 11 through supercharging variable frequency pump 12, and said low discharge compensating tank 9 links to each other with residual quantity compensating tank 8 through tube connector 2.
Said bidirectional compensating device 11 is connected with all families pipe network 6 with the water side of variable frequency pump 10.
Be provided with between said constant voltage compensating tank 7 and the city planting ductwork 1 and have or not vacuum flow amount controller 3 and pressure sensor 4.
The top of said residual quantity compensating tank 8 and low discharge compensating tank 9 is respectively arranged with energy storage device 5.
Normal discharge supplies water the period, and city planting ductwork 1 working condition is good, comes the water pressure and the water yield all can guarantee; City planting ductwork 1 comes water through after not having vacuum flow amount controller 3 entering constant voltage compensating tanks 7 at this moment; One the road supplies with user's pipe network 6 after variable frequency pump 10 pressurizations, and another road gets into bidirectional compensating device 11, in this process; Bidirectional compensating device 11 is communicated with residual quantity compensating tank 8 and supercharging variable frequency pump 12; In order to guarantee the normal water supply of user's pipe network 6, the water outlet one tunnel in bidirectional compensating device 11 of the water under high pressure of bidirectional compensating device 11 gets into residual quantity compensating tank 8, a tunnel and gets in the low discharge compensating tank 9 behind the adherence pressure once more through supercharging variable frequency pump 12.
