Abstract
The invention discloses a variable frequency water supply facility for high-rise buildings. The variable frequency water supply facility comprises a water storage tank which is connected with a municipal pipe network; the water storage tank is connected with a booster pump unit which is connected with a steady flow tank in series; the steady flow tank is connected with a water outlet pipe at the tail end of the pipe network; the booster pump unit comprises at least two supercharging pipelines which are connected between a water outlet pipe of the water storage tank and a water inlet pipe of the steady flow tank in parallel; each supercharging pipeline is at least connected with a water pump and a non-return valve in series; non-return valves are connected on the supercharging pipelines and the pipelines of the steady flow tank; the non-return valves are connected with a supercharging bypass in parallel; the supercharging bypass is at least connected with a small-flow auxiliary pump in series; and the water pump and the small-flow auxiliary pump are connected with a variable-frequency speed regulator. The variable frequency water supply facility can solve the problem that the traditional water supply facility has poor voltage stabilization performance for water supply pipe networks of the high-rise buildings and high energy consumption at the low peak period of water supply.
Description
Technical field
The present invention relates to the supply equipment technical field, especially a kind of supply equipment that is used for the VFC of high-rise water.
Background technology
The supply equipment that existing high residential building uses generally inserts 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 the current stabilization jar 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 simultaneously to guarantee water supply at all water pumps of water use peak.Because the output and the pressure of high residential building are higher; Booster station needs a large amount of water pump of parallel connection 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 influenced 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 by this invention 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; Technical scheme of the present invention is: comprise the water tank that connects city planting ductwork; The delivery port of said water tank is provided with the intake pressure sensor, and said water tank connects the booster water pump group, and said booster water pump group is connected with the current stabilization jar; The water inlet pipe of said current stabilization jar is provided with the discharge pressure sensor, and said current stabilization jar connects the terminal outlet pipe of pipe network; Said 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 said water tank and said current stabilization jar, and every said pressure piping is in series with water pump and flap valve at least; Be in series with a flap valve between the pipeline of said pressure piping and said current stabilization jar, said flap valve is parallel with a supercharging bypass, and said supercharging bypass is in series with the low discharge auxiliary pump at least; Said water pump all is connected variable-frequency governor with said low discharge auxiliary pump.
In the technique scheme, more concrete scheme can be: said low discharge auxiliary pump is in series with the low discharge compensating tank.
Owing to adopted technique scheme, the present invention 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 the size of adjustment supercharging in real time according to the pressure in the pipe network; Make the reduction that changes noticeably of water supply network pressure, even arrive the state of constant pressure, do not increase equipment energy consumption simultaneously again;
2, on the outlet pipe of a plurality of pressure pipings the parallel connection low discharge auxiliary pump; 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; Current stabilization jar 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 embodiment of the invention.
The specific embodiment
Implement the present invention is made further detailed description below in conjunction with accompanying drawing:
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, and the outlet pipe of booster water pump group is provided with discharge pressure sensor 9 and flap valve 8, is in series with current stabilization jar 11 afterwards; The water inlet pipe of current stabilization jar 11 is provided with discharge pressure sensor 9, and current stabilization jar 11 connects the terminal outlet pipe 10 of pipe network.Said 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 current stabilization jar 11, and every said pressure piping is in series with butterfly valve 3, water pump 4, flap valve 5 and butterfly valve 3 successively; Pipeline between said pressure piping and the current stabilization jar 11 is in series with a flap valve 8, and this flap valve 8 is parallel with a supercharging bypass, and said 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; The all water pumps 4 and the rotating speed of low discharge auxiliary pump 7 are all regulated through variable-frequency governor 13.
When water use peak, variable-frequency governor 13 control of pump running supercharging is to guarantee water supply; 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.Current stabilization jar 11 and low discharge compensating tank 12 also can play the effect of voltage stabilization and current stabilization.
