Abstract
The utility model discloses a kind of large flow anti-cavitation pump impeller, comprise: hub seat and the fixed shaft hole of at least 2 blades, stator blade, described fixed shaft hole is in the central authorities of described hub seat, blade is distributed on the wheel hub surface of fixed shaft hole periphery, described blade is triangular vane, in triangular vane, have one side at least for arc shaped surface, described blade, hub seat and fixed shaft hole surface are equipped with anti-cavitation zinc-nickel layer.By the way, the utility model efficiency is high, flow is large, lift is high, impeller in running up, surperficial zinc-nickel layer difficult drop-off, impeller is difficult for getting rusty, and has extended working life; Because overlay coating does not come off, the turbidity test of cooling liquid are good, and the wearing and tearing of water seal friction pair are normal, can relatively increase the service life.
Description
Technical field
The utility model relates to a kind of large flow anti-cavitation pump impeller.
Background technique
All be designed to straight line type for the impeller blade of the large cooling waterpump of large flow in the market, but there is the shortcomings such as flow is little, lift is low in linear blade, can not meet various application demands.
In addition, the impeller surface on market all adopts zinc-plated processing, but in impeller is running up, Zinc coat easily comes off, and impeller easily gets rusty, and has reduced working life; Zinc coat is de-to be fallen behind in cooling liquid, makes water seal friction pair premature wear, and water seal is leaked, and affects working life.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of large flow anti-cavitation pump impeller, can improve lift, enlargement discharge, and impeller is difficult for getting rusty, and has extended working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of large flow anti-cavitation pump impeller is provided, comprise: hub seat and the fixed shaft hole of at least 2 blades, stator blade, described fixed shaft hole is in the central authorities of described hub seat, blade is distributed on the wheel hub surface of fixed shaft hole periphery, described blade is triangular vane, has one side at least for arc shaped surface in triangular vane, and described blade, hub seat and fixed shaft hole surface are equipped with anti-cavitation zinc-nickel layer.
In preferred embodiment of the utility model, it is arc shaped surface that triangular vane is provided with a side, and all the other sides are planarea.
In preferred embodiment of the utility model, it is arc shaped surface that triangular vane is provided with bi-side, and all the other sides are planarea.
In preferred embodiment of the utility model, it is arc shaped surface that triangular vane is provided with three sides, and all the other sides are planarea.
In preferred embodiment of the utility model, the wheel hub surface of stator blade is curved surface.
In preferred embodiment of the utility model, the exit installation angle of described blade is greater than 90 °.
The beneficial effects of the utility model are: the large flow anti-cavitation of the utility model pump impeller efficiency is high, flow is large, lift is high, impeller in running up, surperficial zinc-nickel layer difficult drop-off, impeller is difficult for getting rusty, and has extended working life; Because overlay coating does not come off, the turbidity test of cooling liquid are good, and the wearing and tearing of water seal friction pair are normal, can relatively increase the service life.
