Abstract
The invention discloses a frequency-conversion booster water pump set. The frequency-conversion booster water pump set comprises a main water inlet tube with a water inlet pressure sensor and a main water outlet tube with a water outlet pressure sensor, wherein at least two booster pipelines are at least in parallel connected between the main water inlet tube and the main water outlet tube; each booster pipeline is at least connected with a water pump and a check valve in series; the check valve is connected between the water outlet tube of the booster pipeline and the main water outlet tube in series; a booster bypass is connected between the water inlet tube of the check valve and the water outlet tube; the booster bypass is sequentially connected with a small-flow auxiliary pump and a small-flow compensation tank in series; and the water pump and the small-flow auxiliary pump are connected with a frequency-conversion speed regulator. Compared with the prior art, the frequency-conversion booster water pump can solve the problem that the current booster pump station has poor pressure stabilizing performance for a water supply network of a high-rise residence and high energy consumption at low water supply cycle.
Description
Technical field
The present invention relates to supply equipment, especially a kind of booster water pump group in the pipe network that is connected in parallel on of utilizing variable-frequency governor control.
Background technology
The booster station of existing high residential building use generally all is to adopt many water pump parallel connections, changes starting or stoping water pump to regulate 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 water pump 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 frequency conversion booster water pump group, and is poor for high residential building water supply network voltage regulation performance to solve existing booster station, in the high problem of water supply low peak period energy consumption.
In order to address the above problem; Technical scheme of the present invention is: this frequency conversion booster water pump group comprises main water inlet tube that is provided with the intake pressure sensor and the primary flow pipe that is provided with the discharge pressure sensor; Be parallel with at least two pressure pipings between said main water inlet tube and the said primary flow pipe, every said pressure piping is in series with water pump and flap valve at least; Be in series with flap valve between the outlet pipe of said pressure piping and the said primary flow pipe, be parallel with a supercharging bypass at the water inlet pipe and the outlet pipe of said flap valve, said supercharging bypass is in series with low discharge auxiliary pump and low discharge compensating tank successively; Said water pump all is connected variable-frequency governor with said low discharge auxiliary pump.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, this frequency conversion booster water pump group adopts variable-frequency governor to regulate the pump rotary speed of whole pumping plant, can change the size of adjustment supercharging in real time according to the pressure in the pipe network, makes reductions that change noticeably of water supply network pressure, and the while does not increase equipment energy consumption again;
2, on the outlet pipe of a plurality of pressure pipings the parallel connection low discharge auxiliary pump and low discharge compensating tank; 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; Flap valve has prevented the aqueous reflux through low discharge auxiliary pump pressurization, has reduced the energy consumption of equipment, and low discharge auxiliary pump and low discharge compensating tank can be installed in high level; The 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:
Frequency conversion booster water pump group shown in Figure 1 comprises main water inlet tube 1 that has intake pressure sensor 2 and the primary flow pipe 10 that is provided with discharge pressure sensor 9; Between main water inlet tube 1 and primary flow pipe 10, be parallel with 4 pressure pipings, every said pressure piping is in series with butterfly valve 5, water pump 3, flap valve 4 and butterfly valve 5 successively; Be in series with flap valve 8 between the outlet pipe of said pressure piping and the primary flow pipe 10; Water inlet pipe and outlet pipe at flap valve 8 are parallel with a supercharging bypass; This supercharging bypass is in series with low discharge auxiliary pump 7 and low discharge compensating tank 11 successively, is provided with butterfly valve 5 on the water inlet of low discharge compensating tank 11 and the delivery port; Primary flow pipe 10 is provided with discharge pressure sensor 9; The all water pumps 3 and the rotating speed of low discharge auxiliary pump 7 are all regulated through variable-frequency governor 12.When water use peak, the 3 running superchargings of variable-frequency governor 12 control of pump are 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.Low discharge compensating tank 11 also can play the effect of voltage stabilization and current stabilization.
