The device comprises a water storage tank which is connected with a municipal pipe network, wherein the water storage tank is connected with a booster pump set, the booster pump set is in series connection with a steady flow tank, the steady flow tank is connected with a water outlet pipe at the tail end of the pipe network, the booster pump set comprises at least two booster pipes which are in parallel connection between a water outlet pipe of the water storage tank and a water inlet pipe of the steady flow tank, and each of the booster pipes is at least connected with a water pump and a check valve in series; check valves are connected with the booster pipes and pipes of the steady flow tank, the check valves are in parallel connection with a booster by-pass, and the booster by-pass is in series connection with at least one small-flow auxiliary pump; and both the water pump and the small-flow auxiliary pump are connected with a frequency-conversion speed regulator. According to the high-rise frequency-conversion water supply device, the problems of existing water supply devices that the voltage stabilization performance of water supply pipe networks of high-rise housings is poor, and energy consumption is high in a water supply low cycle are solved.
Description
Technical field
The utility model relates to the supply equipment technical field, especially a kind of supply equipment of the variable frequency control for high-rise water.
Background technology
The supply equipment that existing high residential building uses generally accesses water tank or reservoir by the water pipe of city planting ductwork, water tank connects the booster water pump group tap water is carried out supercharging, advancing tap water after the supercharging flows into steady-flow tank and preserves buffering, water supply when the pipe network terminal temperature difference uses.And the booster water pump group generally is to adopt many water pump parallel connections, changes starting or stoping water pump with the pressure in the pipe network according to the pressure in the pipe network, starts with assure feed water simultaneously at all water pumps of water use peak.Because output and the pressure of high residential building are higher; booster station needs in parallel a large amount of water pumps satisfying the water supply of water use peak, and when night or water supply ebb, user's water supply volume is less; a large amount of water pump frequent start-stop or low-speed running had not only increased equipment energy consumption but also had affected application life of water pump.In addition, mostly the period pump rotary speed of existing booster station is to be driven by the three phase alternating current motor of fixed frequency, can't change according to the pipe network internal pressure in real time to change pump rotary speed, causes the pipe network internal pressure non-constant, supply water and water between uneven, stablize the ability of ductwork pressure.
Summary of the invention
Problem to be solved in the utility model provides a kind of high-rise frequency-changing water supply device, and is poor for high residential building water supply network voltage regulation performance to solve existing supply equipment, the high problem of energy consumption when the water supply ebb.
In order to address the above problem, the technical solution of the utility model is: comprise the water tank that connects city planting ductwork, the delivery port of described water tank is provided with the intake pressure sensor, described water tank connects the booster water pump group, described booster water pump group is connected with steady-flow tank, the water inlet pipe of described steady-flow tank is provided with the discharge pressure sensor, and described steady-flow tank connects pipe network outlet water at tail end pipe; Described booster water pump group comprises at least two pressure pipings between the water inlet pipe of the outlet pipe that is connected in parallel on described water tank and described steady-flow tank, and every described pressure piping is in series with water pump and flap valve at least; Be in series with a flap valve between the pipeline of described pressure piping and described steady-flow tank, described flap valve is parallel with a supercharging bypass, and described supercharging bypass is in series with the low discharge auxiliary pump at least; Described water pump be connected the low discharge auxiliary pump and all connect variable-frequency governor.
In the technique scheme, more specifically scheme can be: described low discharge auxiliary pump is in series with the low discharge compensating tank.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, this high-rise frequency-changing water supply device adopts variable-frequency governor to regulate the rotating speed of whole all water pumps, can change according to the pressure in the pipe network and adjust in real time the supercharging size, make the reduction that is changed significantly of water supply network pressure, even arrive the state of constant pressure, do not increase again equipment energy consumption simultaneously;
2, low discharge auxiliary pump in parallel on the outlet pipe of a plurality of pressure pipings, can when the water supply ebb, stop high powered water pumps all on the pressure piping, the low discharge auxiliary pump of use smaller power can satisfy high-rise user's water, reduced the energy consumption of equipment, and the low discharge auxiliary pump can be installed in high level; Steady-flow tank and low discharge compensating tank also can play the effect of voltage stabilization and current stabilization.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing enforcement:
High-rise frequency-changing water supply device shown in Figure 1 comprises the water tank 1 that connects city planting ductwork, the delivery port of water tank 1 is provided with intake pressure sensor 2, water tank 1 connects the booster water pump group, be provided with discharge pressure sensor 9 and flap valve 8 on the outlet pipe of booster water pump group, be in series with afterwards steady-flow tank 11, the water inlet pipe of steady-flow tank 11 is provided with discharge pressure sensor 9, and steady-flow tank 11 connects pipe network outlet water at tail end pipe 10.Described booster water pump group comprises four pressure pipings on the water inlet pipe of the outlet pipe that is connected in parallel on water tank 1 and steady-flow tank 11, and every described pressure piping is in series with butterfly valve 3, water pump 4, flap valve 5 and butterfly valve 3 successively; Pipeline between described pressure piping and the steady-flow tank 11 is in series with a flap valve 8, and this flap valve 8 is parallel with a supercharging bypass, and described supercharging bypass is in series with the butterfly valve 3 on low discharge auxiliary pump 7 and low discharge compensating tank 12 and low discharge compensating tank 12 water inlet pipe and water outlet pipes; All water pumps 4 and the rotating speed of low discharge auxiliary pump 7 are all regulated by variable-frequency governor 13.
When water use peak, variable-frequency governor 13 control pump operation superchargings are with assure feed water; When not starting low discharge auxiliary pump 7, if discharge pressure sensor 9 has reached preset value, current can directly supply water through flap valve 8 without the supercharging bypass, play the effect that cushions the peak that disappears; When the water supply ebb, be that the numerical value of intake pressure sensor 2 is during near preset value, stop high powered water pump all on the pressure piping 3, use low discharge auxiliary pump 7 superchargings of smaller power, so that discharge pressure sensor 9 reaches preset value, can satisfy high-rise user's water, reduce the energy consumption of equipment.Steady-flow tank 11 and low discharge compensating tank 12 also can play the effect of voltage stabilization and current stabilization.
