Description
Technical Field
The utility model relates to a vertical diagonal flow pump, concretely relates to high-efficient vertical diagonal flow pump of loosing core.
Background
The existing vertical diagonal flow pump is more and more widely applied, in particular to a pump with large flow, large caliber and large power. The core-pulling mixed flow pump with the common design is limited by the hydraulic structure design, and the guide vane body and the impeller chamber need to be pulled out along with the rotatable component, so that the hoisting quality of the core-pulling component is increased, and the problem of difficult installation and disassembly exists; the impeller is easy to generate unstable phenomenon due to impurities in water flow in the running process; the guide blade body is rectangular, which causes unnecessary energy loss.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a simple, stable in structure's high-efficient vertical diagonal flow pump of can loosing core is dismantled in the installation.
In order to realize the technical purpose, the utility model discloses a scheme is: an efficient vertical core-pulling diagonal flow pump, comprising: rotor and casing, the casing include import loudspeaker, import loudspeaker set up the downside at the casing, import loudspeaker upside be provided with the impeller chamber, the impeller chamber upside be provided with the guide vane body, guide vane body upside be provided with the connecting pipe, the casing in be provided with the rotor, the rotor on be provided with a support spare, support spare and casing between fixed through the mounting, the rotor include: the pump shaft, pump shaft upper portion be provided with the rigid coupling, the rigid coupling downside be provided with the protecting pipe, the protecting pipe downside be provided with the supporting seat, the supporting seat downside be provided with toper support piece, toper support piece downside be provided with the closing plate, the closing plate downside be provided with slide bearing, the slide bearing outer lane be provided with interior impeller, the slide bearing downside be provided with outer impeller.
The support piece is arranged between the rigid coupling and the protective sleeve.
The blade direction of the inner impeller is upward, and the blade direction of the outer impeller is downward.
The combined shape of the impeller chamber and the guide vane body is an ellipse.
The length of the sealing plate is smaller than the inner diameter of the connecting pipe.
The shape of the outer impeller is matched with the shape of the impeller chamber.
The utility model has the advantages that: the rotor component can be drawn out from the shell, the installation and the disassembly are simple, and the hoisting weight is light; by arranging the inner impeller, water flow is stabilized, vibration of the pump shaft is avoided, and the stability and the service life of the pump shaft are improved; the lower part of the shell adopts an oval structure, so that the space is increased, the bottom of the shell adopts a horn shape, the flow is increased, and the efficiency is improved.
