The constant-pressure water supply device is stable and accurate in pressure regulation, does not require frequent starting and stopping of a plurality of sets of pumps, and lowers impact to a pipe network.
Description
Technical field
The utility model relates to a kind of supply equipment, more precisely a kind of constant pressure water supply equipment.
Background technology
At present, in some production occasion, industrial water need remain under a certain constant compression force.Prior art is to adopt the pump group of many low discharges to control, and according to required pressure, determines out how many platform pumps, when pressure is lower than setting value, starts some pumps more, when pressure is higher than setting value, just closes some pumps.But this pressure controling mode, pressure is regulated unstable, can not realize accurately regulating, and the start and stop pump is bigger to the compression shock of pipe network continually.
This shows how prior art is improved, a kind of constant pressure water supply equipment is provided, it is stable, accurate that pressure is regulated, and reduces the compression shock to pipe network, and this is present this area technical issues that need to address.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of constant pressure water supply equipment, and the water liquid of certain hydraulic pressure can stably, accurately be provided, and reduces the compression shock to pipe network.
For solving above technical problem, a kind of constant pressure water supply equipment of the present utility model, the power frequency control pump that comprise water supply container, is connected with water supply container and variable frequency control pump, the outlet pipe that described power frequency control pump and variable frequency control pump pass through separately respectively is connected with outfall sewer, is equipped with control valve in the outlet pipe.
Preferably, described power frequency control pump and described variable frequency control pump are respectively equipped with water inlet pipe, and water inlet pipe all is connected with a water inlet manifold, and water inlet manifold is connected with water supply container.
Preferably, described water supply container comprises main body and is arranged on the support of main body below.
Preferably, also comprise one for the controller that control valve is controlled.
Compared with prior art, constant pressure water supply equipment of the present utility model, because being set, power frequency regulates pump and variable frequency adjustment pump, the water inlet of the two all is connected with a water supply container, power frequency is regulated pump and the variable frequency adjustment pump is respectively equipped with outlet pipe, be connected with outfall sewer by outlet pipe, supplied water to the external world by outfall sewer, be equipped with control valve in the outlet pipe separately, because can making hydraulic pressure regulate arbitrarily between 0～a certain value, the variable frequency control pump changes, thereby when hydraulic pressure reduces, can start the variable frequency control pump earlier and carry out variable frequency adjustment, when rising to power frequency as if the variable frequency control pump frequency, hydraulic pressure also reduces, then start the power frequency control pump, the variable frequency control pump carries out variable frequency adjustment according to variation in water pressure, this shows, constant pressure water supply equipment of the present utility model, pressure is regulated stable, accurately, need not open and close many pumps continually, reduce the compression shock to pipe network.

The specific embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the constant pressure water supply equipment in the present embodiment comprises water supply container 1, power frequency control pump 2, variable frequency control pump 3, and power frequency control pump 2 is connected with in first water inlet pipe 5, first outlet pipe, 7, the first outlet pipes 7 and is provided with the first outlet water control valve 7a; Variable frequency control pump 3 is connected with in second water inlet pipe 6, second outlet pipe, 8, the second outlet pipes 8 and is provided with the second outlet water control valve 8a.First water inlet pipe 5 and second water inlet pipe 6 all are connected with a water inlet manifold 4, and water inlet manifold 4 is connected with water supply container 1.First outlet pipe 7 and second outlet pipe 8 all are connected with an outfall sewer 9, by the water liquid of outfall sewer 9 to external world's supply certain pressure.
The constant pressure water supply equipment of present embodiment also comprises a controller, and this controller is used for the switching of control first outlet water control valve and second outlet water control valve and the frequency of control variable frequency control pump.Because can making hydraulic pressure regulate arbitrarily between 0～a certain value, the variable frequency control pump changes, thereby when hydraulic pressure reduces, can start the variable frequency control pump earlier and carry out variable frequency adjustment, when if the variable frequency control pump frequency rises to power frequency, hydraulic pressure also reduces, then start the power frequency control pump, the variable frequency control pump carries out variable frequency adjustment according to variation in water pressure.
In the present embodiment, because can making hydraulic pressure regulate arbitrarily between 0～a certain value, the variable frequency control pump changes, thereby when hydraulic pressure reduces, can start the variable frequency control pump earlier and carry out variable frequency adjustment, if when the variable frequency control pump frequency rose to power frequency, hydraulic pressure also reduced, and then starts the power frequency control pump, the variable frequency control pump carries out variable frequency adjustment according to variation in water pressure, this shows that constant pressure water supply equipment of the present utility model, pressure are regulated stable, accurate, need not open and close many pumps continually, reduce the compression shock to pipe network.
More than the utility model is described in detail, use specific case in the literary composition principle of the present utility model and embodiment set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
