Description
Technical field:
The utility model relates to a kind of volute chamber more meeting the pump body of fluid mechanics and Swirl intensity retention, relates to hydraulic transmission field.
Background technique:
Whirlpool centrifugal pump is applied to nonlubricious fluid and the very low occasion of net positive suction head, is applicable to conveying gas-liquid mixed media and volatile medium, as: gasoline, alcohol, methyl alcohol etc.It is a kind of high-lift, industrial pump that small flow, construction profile are light and handy.Prime mover is driven in pump during vane rotary by axle, and liquid enters runner by inhaling population, is subject to the centrifugal action of rotary blade, is thrown toward in surrounding ring runner, and liquid is flowed in runner.Because each liquid particle is subject to the effect of centrifugal force, inside impeller, liquid is large by the effect of centrifugal force, and liquid is little by the effect of centrifugal force in runner, and the centrifugal force suffered by both varies in size, and thus causes liquid to do longitudinal vorticla motion.Liquid relies on longitudinal vortex in runner, flow through interlobate passage repeatedly (Fig. 1-35) again and again.Liquid often asks passage through primary vane, and lift just increases once, is finally extruded by liquid and discharges.Liquid just forms parital vacuum in inter-blade channel after discharging, and liquid is just continuous enters impeller from suction port, and repeats above-mentioned movement process.Peripheral pump one side inhales people's liquid like this, and one side discharges liquid, thus constantly works.
Whether the volute chamber of current whirlpool centrifugal pump meets optimum fluid mechanics principle, depends on the design of intake position and the water outlet physical location of the pump housing.The water intake of conventional whirlpool centrifugal pump and water outlet all vertical parallel distributions of Central Symmetry on pumping section, because water intake and water outlet are in the adjacent same direction of pump, during vortex centrifugal pump work, vane rotary works, because intake-outlet crow flight distance is short, water inlet position is improper, Maximum differential pressure when effectively can not produce vane rotary supercharging and maximum dough nut effect, causes can not reaching the high-lift of design code and flow under the transmission of configuration active force.
Model utility content:
For the problems referred to above, the technical problems to be solved in the utility model be to provide one make whirlpool centrifugal pump operationally vane rotary more can produce the pump body volute chamber of " annularly flow "; When the impeller is rotated, under the influence of centrifugal force, in impeller, the peripheral velocity of liquid is greater than the peripheral velocity of liquid in runner, again owing to following impeller to advance from suction port to exhaust port liquid, the synthesis result of these two kinds motions, just makes liquid produce eddy current in rational pump housing volute chamber; The peripheral velocity of liquid in pump housing runner is less than the peripheral velocity of impeller.The pump housing volute chamber meeting fluid mechanics principle highlyer effectively can improve the peripheral velocity of the liquid in pump housing runner.
A kind of whirlpool centrifugal pump of the present utility model, it adopts in the structural design of the pump housing carries out renewal change, and former superincumbent water intake is removed, and rotated ninety degrees, is arranged on horizontal position, and the intake chamber of pumping section inside also does corresponding change; Water outlet arranged in parallel with water intake above the former pump housing is moved to the neutral position vertically upward of the pump housing, the volute chamber runner of pump body also does mobile amendment.The volute chamber of former trapezoid cross section design change circular cross-section into, in longitudinal vortex process, liquid repeatedly enters between impeller blade, by impeller blade energy transferring to the liquid particle in runner.Liquid, often through primary vane, just obtains primary energy.In the work of whirlpool centrifugal pump, not all liquid all passes through impeller, along with the increase of flow, and the declines of annularly flow; When flow is zero, lift is the highest; By the improvement of pump housing volute chamber, when guaranteed flow is constant, lift increases, and energy consumption reduces.
This project preferred, the volute chamber of described a kind of whirlpool centrifugal pump, former also Column Layout's pump housing water inlet and outlet volute chamber structure change on whirlpool centrifugal pump, the water intake rotated ninety degrees of the pump housing changes horizontal position into, and the water intake of pump housing volute chamber synchronously changes horizontal position into and is connected with the water intake of the pump housing; Due to the change of entrance location, follow impeller to advance from suction port to exhaust port liquid, the synthesis result of these two kinds motions, liquid is produced and turns to identical larger " longitudinal vortex " with impeller.Improve the peripheral velocity of liquid in pump housing runner, under the prerequisite ensureing whirlpool Centrifugal Pump, improve lift, reduce energy consumption.
The beneficial effects of the utility model are: reasonable in design, effective applicating fluid transmission mechanics principle, improve lift of pump.Effect is directly obvious.
