Description
Technical field
The present invention relates to a kind of liquid transporting apparatus, more particularly, to a kind of liquid transporting apparatus of low lift and large flow rate.
Background technology
In city inland river ecological management, because its water body flow is slow, aggravated the black smelly, algae infestation of river water body and
Bed mud alluvial problem, these problems can effectively be mitigated by improving the mobility of water body.
A kind of method for improving city inland river water body flow is that the water of river course one end is got into the other end with pump, so that
In river course water body produce flowing, its water body convey the characteristics of for 0.1-0.3m low lift and 1-10m3/ s big flow.And
In current liquid transporting apparatus, the conveying of the water body of low lift and big flow is mainly completed by axial-flow pump.By to axial-flow pump
Major parameter research be not difficult to find out, the lift of axial-flow pump optimal working point is more than 2m, and now efficiency is 85% or so；Work as lift
For 1m when, efficiency then be less than 75%；When lift is 0.3m, efficiency is less than 30%；And when lift is 0.1m, efficiency is even more
Less than 15%.Therefore river water body is carried out using axial-flow pump and makes stream to cause a large amount of wastes of electric energy, operating cost is also very high.This
Outside, because axial-flow pump power is larger and rotating speed is higher, noise is larger during operation；And because axial-flow pump rotating speed is higher, during operation
Its impeller can be also brought compared with major injury to the small-sized biological in river water body, be unfavorable for building good water ecological setting.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of Energy Efficiency Ratio is high, noise is small and will not be in river water body
The low lift and large flow rate liquid transporting apparatus that small-sized biological damages.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of low lift and large flow rate liquid conveying dress
Put, including the runner being made up of a bottom surface and two sides and the impeller being arranged on above described runner, described impeller
Device of rotation driving is provided with, described impeller is by rotating shaft and the former for the multi-disc equal length being uniformly arranged around described rotating shaft
Form, described bottom surface is provided with the arc surface positioned at the lower section of described impeller, the center of circle of described arc surface with it is described
The center superposition of rotating shaft, the central angle of described arc surface are more than or equal to the piece number of 360 degree divided by described former, and described turns
The output speed of dynamic drive device is less than or equal to 60rpm.
Described device of rotation driving is made up of motor and speed reducer structure.
Described device of rotation driving is motor.
The output speed of described device of rotation driving is 1-10rpm.
The quantity of described former is 8-16 pieces.This selection is that to have considered be former weight and cost；And conveniently
Realize and water space is formed between impeller and runner.
The central angle of described arc surface is less than or equal to the 3 piece numbers for being multiplied by 360 degree divided by described former.
Described former is shaped as plane or curved surface, the rotation side of the bending direction of described curved surface and described impeller
To opposite.
The both sides of described former are provided with side plate.
Lower gap is provided between described former and described arc surface, is set between described former and described side
It is equipped with side clearance.Set gap to be easy to reduce the friction between impeller and runner, improve transfer efficiency.
The side of described former is provided with flexible side shirt edge, and the lower surface of described former sets flexible skirt side.
This setting is to prevent the lower surface of former from causing the stuck of impeller after being contacted with arc surface.
Compared with prior art, the advantage of the invention is that being designed using the slow-speed of revolution less than 60rpm, its big flow is benefited
The water space formed between each face in its impeller and runner, even therefore can also be obtained under relatively low rotating speed larger
Flow.Because rotating speed is relatively low, required power of motor is smaller, therefore the efficiency of the present invention is higher, and running noises are relatively low；Due to turning
Speed is relatively low, flow channels are big, and the time that the small-sized biological in water body has abundance is averted danger, and it is injured so as to reduce device,
Water ecological setting is adversely affected smaller.Sum it up, the liquid transporting apparatus efficiency high of the present invention, running noises are low, right
Eco-friendly.The central angle of arc surface is more than or equal to the piece number of 360 degree divided by described former, then can make impeller former
Between at least form 1 water space, the central angle of arc surface, which is less than 360 degree divided by the piece number of described former, can make outlet side
Water body has the chance for being back to inlet side, causes efficiency to reduce；And the central angle of arc surface be multiplied by less than or equal to 3 360 degree divided by
The piece number of former, then it can ensure that the height of arc surface will not be too high, and the excessive height of arc surface can reduce flow section face
Accumulate and inlet and outlet is sprung up increase, increase the consumption of idle work, can equally reduce efficiency.
Wheel speed is due to that the too fast closed space that influent side can be caused newly to be formed of wheel speed has little time less than 60rpm
Moisturizing, the water surface is spilled over during liquid discharge in the closed space of water outlet side, both of which can increase disappearing for liquid conveying idle work
Consumption, so as to reduce efficiency；Simultaneously can also weight increasing device by water impact dynamics, made an uproar so as to reduce service life and increase operation
Sound.And 1-10rpm is selected then to ensure that each performance is optimum state.
