Description
Technical field
The utility model relates to a kind of frequency-changing water supply device, particularly relates to a kind of frequency-changing water supply device with super-pressure chamber small flow pressure maintaining function.
Background technology
In the Design of Waterworks process of prior art, when the water yield of certain instantaneous or certain period in outdoor water supply pipe net, hydraulic pressure can not meet the water yield, the hydraulic demand of pipe network in house, then needing, secondary pressurized equipment is set a water is promoted thus meets user's water demand.
The second pressure water supply equipment used that is communicated with reservoirs and tanks main in the market has, frequency-changing water supply device and box type negative-pressure-free supply equipment, and confession that can be concrete according to project, condition is needed to match, but in actual application, in vacuum tank set by the pressurized equipment port of export, pressure is only pressure needed for user's least favorable water distribution point, when water supply is when carrying out work in low discharge section, variable-frequency motor is in closed condition, the water yield of vacuum tank effective compensation is less, thus cause variable frequency pump start and stop frequent, particularly night, this kind of phenomenon is comparatively obvious, the not only serious application life affecting variable frequency pump, voltage stabilizing function is not enough, discharge pressure is unstable, and electric energy loss is larger, be unfavorable for saving the energy.
Utility model content
In view of this; main purpose of the present utility model is to provide a kind of frequency-changing water supply device with super-pressure chamber small flow pressure maintaining function; pass through the technical program; at water supply flow low-valley interval; under variable frequency pump stopped status; still effectively can ensure that user side is to the water yield and hydraulic demand, normal water supply, and the small flow pressure maintaining function that the long period can be guaranteed.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of frequency-changing water supply device with super-pressure chamber small flow pressure maintaining function, comprise water tank, variable frequency pump, water inlet gathering tube and outlet gathering tube, municipal administration carrys out grid and is connected with water tank water intake end, the water side of water tank is connected with water inlet gathering tube, the water inlet end of described variable frequency pump is connected with water inlet gathering tube, described outlet gathering tube is connected with grid with user with variable frequency pump water side respectively, also comprise super-pressure chamber compensating tank, storage pump and bidirectional compensator, the compensation end of described bidirectional compensator is connected with super-pressure chamber compensating tank, the input of bidirectional compensator is connected with accumulation of energy delivery side of pump, the input of storage pump is connected with outlet gathering tube with the output of bidirectional compensator.
Described super-pressure chamber compensating tank is airbag boost air tank.

Beneficial effect after employing technique scheme is: a kind of frequency-changing water supply device with super-pressure chamber small flow pressure maintaining function; pass through the technical program; ad hoc meter has the frequency-conversion water supply system of small flow pressure maintaining function; at water supply flow low-valley interval; under variable frequency pump stopped status; still effectively can ensure that user side is to the water yield and hydraulic demand, normal water supply, and the small flow pressure maintaining function that the long period can be guaranteed.
Accompanying drawing explanation
Fig. 1 is overall structure figure of the present utility model.
In figure, 1 water tank, 2 variable frequency pumps, 3 water inlet gathering tubes, 4 outlet gathering tubes, 5 municipal administrations come grid, 6 users with grid, 7 super-pressure chamber compensating tanks, 8 storage pumps, 9 bidirectional compensators, 10 without vacuum flow amount controller.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.
As shown in Figure 1, the frequency-changing water supply device of super-pressure chamber small flow pressure maintaining function that what the utility model related to have, comprise water tank 1, variable frequency pump 2, water inlet gathering tube 3 and outlet gathering tube 4, municipal administration carrys out grid 5 and is connected with water tank 1 water inlet end, the water side of water tank 1 is connected with water inlet gathering tube 3, the water inlet end of described variable frequency pump 2 is connected with water inlet gathering tube 3, described outlet gathering tube 4 is connected with grid 6 with user with variable frequency pump 2 water side respectively, also comprise super-pressure chamber compensating tank 7, storage pump 8 and bidirectional compensator 9, the compensation end of described bidirectional compensator 9 is connected with super-pressure chamber compensating tank 7, the input of bidirectional compensator 9 is connected with the output of storage pump 8, the input of storage pump 8 is connected with outlet gathering tube 4 with the output of bidirectional compensator 9.
Described super-pressure chamber compensating tank 7 is airbag boost air tank.
Described water tank 1 water inlet end is provided with without vacuum flow amount controller 10.
Normal discharge supplies water period and use discharge peak period; the water that municipal administration carrys out grid 5 enters into water tank 1; under the protection without vacuum flow amount controller 10; effectively can protect city planting ductwork 5 safety water supply; current in water tank 1 enter into variable frequency pump 2 by water inlet gathering tube 3; be supplied to user with grid 6 by the pressurization of outlet gathering tube 4, when normal discharge supplies water, water is squeezed in super-pressure chamber compensating tank 7 stand-by by storage pump 8 and bidirectional compensator 9 by outlet gathering tube 4.
Low discharge uses the water period, variable frequency pump 2 quits work, control system controls bidirectional compensator 9 and switches to super-pressure chamber compensating tank 7 with outlet gathering tube 4 in conducting state, now super-pressure chamber compensating tank 7, by bidirectional compensator 9, outlet gathering tube 4 and user are compensated by the water yield that grid 6 carries out continuous and effective, thus effectively meet user's low discharge water demand.
In the process, super-pressure chamber compensating tank 7 inner high voltage water carries out level pressure compensation by the water side of bidirectional compensator 9, greatly improves equipment small flow pressure maintaining water supply function.
The above, be only better possible embodiments of the present utility model, and be not used to limit scope of the present utility model.
