Technical field：
The present invention relates to a kind of axial-flow pumps convenient for adjustment of blade angle, belong to mechanical equipment technical field.
Background technology：
Axial-flow pump impeller is equipped with 2~7 blades, is rotated in tubular pump case.Equipped with fixation on the pump case of upper impeller
Guide vane is allowed to become being axially moved, and the kinetic energy of rotary motion is changed into pressure energy to eliminate the rotary motion of liquid.
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.
The adjustment of blade angle of existing axial-flow pump generally uses the adjustment structure of turbine and worm, and structure is complex, and
And regulating member is easily damaged, and influences the service life of axial-flow pump.
Invention content：
The purpose of the present invention is provide a kind of axial-flow pump convenient for adjustment of blade angle, structure in view of the above problems
It is simple convenient for adjusting and sturdy and durable.
Above-mentioned purpose is realized by following technical scheme：
Convenient for the axial-flow pump of adjustment of blade angle, including the first pump case and the second pump case for being connect with the first pump case, it is described
The second pump case be arranged in the top of first pump case, the first pump case bottom is provided with water-inlet horn mouth, top
It is provided with Discharging bent-tube, power plant is provided with inside second pump case, 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 blade, the blade described in every is mounted on by ball head universal to be put on the shaft end of the driving axis connection, each described
Ball head universal annular interlocking lever is connected by connecting rod, positioning plate is welded on the annular interlocking lever, screw rod passes through institute
The positioning plate stated simultaneously is connect with adjusting nut, and the adjusting nut is arranged by snap-gauge in the inside of the first pump case.
The axial-flow pump convenient for adjustment of blade angle, the power plant use electro-motor.
Advantageous effect：
1. the present invention is linked all blades together by annular interlocking lever, pass through the system that adjusting nut realizes blade
One is adjusted, and adjusting method is simpler and equipment overall structure is simply convenient for adjusting and sturdy and durable.

Specific implementation mode：
Embodiment 1：
As shown in Figure 1：The axial-flow pump convenient for adjustment of blade angle of the present embodiment, including the first pump case 1 and with first pump
Second pump case 2 of shell connection, second pump case are arranged in the top of first pump case, the first pump case bottom
It is provided with water-inlet horn mouth 3, top is provided with Discharging bent-tube 4, and power plant 5 is provided with inside second pump case, described dynamic
Power apparatus connects drive shaft 6, and the drive shaft passes through first pump case and extended downwardly along the axial centre of the first pump case,
The lower part of the drive shaft is provided with guide vane 7 and blade 8, the blade described in every by ball head universal 9 be mounted on it is described
The shaft end of driving axis connection is put on, and each ball head universal connects annular interlocking lever 10, the annular by connecting rod
Positioning plate 14 is welded on interlocking lever, screw rod 11 passes through the positioning plate and connect with adjusting nut 12, the adjusting spiral shell
Mother is arranged by snap-gauge 13 in the inside of the first pump case.All blades are linked one by annular interlocking lever in the present embodiment
It rises, realizes that the unified of blade is adjusted by adjusting nut, adjusting method is simpler and equipment overall structure is simply convenient for adjusting
It saves and sturdy and durable.As long as rotating adjusting nut can be realized when adjusting angle.
The axial-flow pump convenient for adjustment of blade angle, the power plant use electro-motor.
The technical means disclosed in the embodiments of the present invention is not limited to the technical means disclosed in the above technical means, and further includes
The technical solution being made of the above technical characteristic equivalent replacement.The unaccomplished matter of the present invention, belongs to those skilled in the art's
Common knowledge.
