Abstract
The utility model discloses a frequency conversion booster water pump set. The frequency conversion booster water pump set comprises a main water inlet pipe and a main water outlet pipe, wherein a water inlet pressure sensor is arranged on the main water inlet pipe; a water outlet pressure sensor is arranged on the main water outlet pipe; at least two booster pipelines are arranged between the main water inlet pipe and the main water outlet pipe in parallel; a water pump and a check valve are at least connected to each booster pipeline in series; a check valve is connected between a water pipe and the main water outlet pipe of the booster pipeline in series; a booster bypass is connected to the water inlet pipe and the water outlet pipe of the check valve; a small-flow auxiliary pump and a small-flow compensation tank are sequentially connected to the booster bypass in series; and frequency conversion governors are respectively connected to the water pump and the small-flow auxiliary pump. Compared with the prior art, the frequency conversion booster water pump set disclosed by the utility model has the advantage that the problem that a traditional booster pump has poor stable performance for a water supply pipeline network of a high-rise residence and high energy consumption during low peak of water supply can be solved.
Description
Technical field
The utility model relates to supply equipment, especially a kind of booster water pump group in the pipe network of being connected in parallel on of utilizing variable-frequency governor control.
Background technology
The booster station that existing high residential building uses 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 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 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 in the utility model provides a kind of freq uency conversion supercharging 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, the technical solution of the utility model is: this freq uency conversion supercharging water pump group comprises the main water inlet tube that is provided with the intake pressure sensor and is provided with the primary flow pipe of discharge pressure sensor, be parallel with at least two pressure pipings between described main water inlet tube and the described primary flow pipe, every described pressure piping is in series with water pump and flap valve at least; Be in series with flap valve between the outlet pipe of described pressure piping and the described primary flow pipe, be parallel with a supercharging bypass at water inlet pipe and the outlet pipe of described flap valve, described supercharging bypass is in series with low discharge auxiliary pump and low discharge compensating tank successively; Described water pump be connected the low discharge auxiliary pump and all connect variable-frequency governor.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, this freq uency conversion supercharging water pump group adopts variable-frequency governor to regulate the pump rotary speed of whole pumping plant, can change according to the pressure in the pipe network to adjust in real time the supercharging size, makes reductions that be changed significantly of water supply network pressure, and the while does not increase again equipment energy consumption;
2, in parallel low discharge auxiliary pump and low discharge compensating tank 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, flap valve has prevented the aqueous reflux through the pressurization of low discharge auxiliary pump, 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 utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing enforcement:
Freq uency conversion supercharging water pump group shown in Figure 1 comprises the main water inlet tube 1 and the primary flow pipe 10 that is provided with discharge pressure sensor 9 with intake pressure sensor 2, be parallel with 4 pressure pipings between main water inlet tube 1 and primary flow pipe 10, every described 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 described 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; All water pumps 3 and the rotating speed of low discharge auxiliary pump 7 are all regulated by variable-frequency governor 12.When water use peak, the 3 running superchargings of variable-frequency governor 12 control water pumps 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.Low discharge compensating tank 11 also can play the effect of voltage stabilization and current stabilization.
