Abstract
The invention relates to a centrifugal pump structural design with an inducer with long and short vanes. The vanes of the inducer comprise long vanes and short vanes which are arranged alternately. The inducer with the long and short vanes is arranged in front of an inlet of an impeller of the centrifugal pump. By the inducer with the structure, the flow condition of an inlet of a main impeller can be improved, and anti-cavitation performance of the inducer can be improved. The centrifugal pump structure with the inducer with the long and short vanes can effectively improve the anti-cavitation performance of a pump effectively.
Description
Technical field
The present invention relates to a kind of centrifugal pump structure design, particularly a kind of centrifugal pump structure design of belt length short blade inducer with inducer
Background technique
At present, the centrifugal pump structure of known band inducer is made up of general inducer, impeller, spiral case and motor.Inducer, impeller are connected with motor shaft, convection cell acting under the drive of axle.Get the nod to improving the pump anti-cavitation performance though increase inducer, the anti-cavitation performance that improves inducer itself is still had a lot of approach at impeller inlet.
Summary of the invention
For addressing the above problem, the present invention adopts belt length short blade inducer, and the anti-cavitation performance that this geometric condition through adjustment inducer blade inlet improves centrifugal pump is a kind of very effective method of improving cavitation performance of centrifugal pump.
Realize that above-mentioned purpose adopted technological scheme be:
The blade of inducer is divided into two kinds of linear leaf and short blades, deviated splitter vane alternately, inducer and main impeller are coaxial, are contained in the main impeller front.Adopt the structure of this cooperation, effectively improve main impeller inlet flow situation, improve the anti-cavitation performance of inducer itself and pump.
The invention has the beneficial effects as follows: reduced the net positive suction head of pump (main impeller), improved the anti-cavitation performance of inducer itself and main impeller, externally properties influence is little.
The present invention is on probation through the user, and reaction effect is good, can reduce investment outlay effectively, energy saving.
Description of drawings
Fig. 1 is the centrifugal pump structure figure of the belt length short blade inducer of one embodiment of the invention
Fig. 2 is same embodiment's a deviated splitter vane inducer schematic representation
Among the figure: 1. the pump housing, 2. main impeller, 3. inducer, 4. linear leaf, 5. short blade
Embodiment
Fig. 1, Fig. 2 have confirmed the centrifugal pump structure form of belt length short blade inducer in the present embodiment jointly; It is made up of the pump housing (1), main impeller (2), inducer (3), linear leaf (4) and short blade (5); If impeller is made deviated splitter vane; Do not influence enforcement of the present invention, because the present invention's control is the centrifugal pump structure of belt length short blade inducer yet.The inducer blade is divided into (4) two kinds of linear leaf (3) and short blades, deviated splitter vane alternately, this structure can be improved main impeller inlet flow situation, improves the anti-cavitation performance of inducer own.The centrifugal pump structure of this belt length short blade inducer can effectively improve the anti-cavitation performance of pump.
Claims (3)
1. the centrifugal pump structure of belt length short blade inducer design, comprise the pump housing (1), main impeller (2), inducer (3),, linear leaf (4), short blade (5), pump cover (6), main shaft (7) and motor (8).
2. centrifugal pump structure design according to claim 1 comprises the structural design between belt length short blade inducer (3) and impeller (2), the pump housing (1).
