Axial-flow pump is typically single stage type, and stage type is made in minority.Range of flow is very big, be 180~360 ten thousand steres/when；Lift is general
At 20 meters or less.Axial-flow pump is generally vertical, and impeller is immersed under water, also there is horizontal or inclined axial flow.Small axial flow pump
Impeller installation site when being higher by the water surface, need to be started with vacuum pump discharges diversion.The blade of axial-flow pump point is fixed and adjustable
Two kinds of structures of formula.The applying working condition of Large Axial Flow Pump often needs to make larger variation in operation, and the established angle of regulation blade can
Pump is set to be maintained at high efficient area operation under different operating modes.The blade angle of pony pump is usually fixed.Axial-flow pump is main
Suitable for low lift, the occasion of big flow, as irrigated, draining flooded fields, dock drains, the water level regulation of canal ship lock, or is used as power plant
System in Large Circulating Water Pump.The higher axial-flow pump of lift（Twin-stage is made when necessary）It is used for the hydraulic jet propulsion of shallow draft ship.
A water outlet is generally only arranged in existing axial-flow pump, when needing liquid being transported to several different directions
Second diffluence equipment is often carried out, causes entire pipelining equipment complicated, installation is inconvenient, and equipment cost is high.
Invention content：
The purpose of the present invention is providing a kind of multi-outlet axial-flow pump in view of the above problems, used in needing liquid
Several different directions are transported to, second diffluence equipment is not needed, integration degree is high, and equipment cost is low.
Above-mentioned purpose is realized by following technical scheme：
Multi-outlet axial-flow pump, including the first pump case and the second pump case for being connect with the first pump case, first pump case
Bottom is provided with water-inlet horn mouth, and top is provided with Discharging bent-tube, and second pump case is arranged in first pump case
Top, the second pump case the inside are provided with power plant, and the Discharging bent-tube connects equal pressure chamber, equal pressure chamber connection
Two or more water outlets, each water outlet are provided with valve, and the power plant connects drive shaft, the driving
Axis passes through first pump case and is extended downwardly along the axial centre of the first pump case, and the lower part of the drive shaft is provided with guide vane
And one stage impeller, turbine, the turbine connecting worm are provided in the drive shaft, the worm screw connects two-stage pressurizing
Impeller, the two-stage pressurizing impeller are arranged at the center of the equal pressure chamber.
The multi-outlet axial-flow pump, the equal pressure chamber are hollow ball-shape structure.
Advantageous effect：
1. the present invention shunts again after being pressurizeed to liquid by setting equal pressure chamber, it is ensured that the liquid each exported
Pressure is balanced, and valve is arranged in each exit, and the outlet of different number can be selected to carry out the conveying of liquid as needed,
Used in needing liquid being transported to several different directions, second diffluence equipment is not needed, integration degree is high, and equipment cost is low.
2. the equal pressure chamber of the present invention is hollow ball-shape structure, voltage equalizing is more preferable.
