Abstract
The invention discloses a pumping chamber of a volute type mixed-flow pump, which comprises a guide blade and a volute, wherein water flow flows through the guide blade after the impeller wheel of the mixed-flow pump works for pressurization, and then enters the volute. In the traditional volute type mixed-flow pump, liquid is collected through a volute and guided to a discharge pipe and the kinetic energy of the liquid is converted into pressure energy; and under the condition that water flow is just under the action of centrifugal force, the volute is a very good pumping chamber. Aiming at that water flow inside the mixed-flow pump is further under the action of lift force, the radial guide blade additionally arranged can convert the circular vector at the outlet of the pump formed by the lift power into water pressure better, so that the head loss can be reduced and the water pump efficiency is improved.
Description
Technical field
The present invention relates to a kind of pumping chamber of Volute mixed-flow pump.
Background technique
Volute mixed-flow pump belongs to the middle-size and small-size water pump of medium lift, is widely used in agricultural irrigation draining, cities and towns water supply and sewage, each field of industrial production of national economy, has that high efficient area is wide, a stability of flow, simple in structure, the advantage such as running is reliable and easy to maintenance.The pumping chamber of traditional Volute mixed-flow pump is spiral case, spiral case is a kind of reasonable structure that is subjected to the current of centrifugal action for collection, because not only being subject to centrifugal action, current in the mixed flow pump also are subject to the lift effect, therefore only depend on spiral case fully not to be converted into water pressure to the water outlet circular rector, and cause that loss of head is large, pump efficiency is not high, be unfavorable for saving energy and reduce the cost.
Summary of the invention
The pumping chamber that the present invention will solve existing Volute mixed-flow pump only considers that current in the pump are subject to centrifugal action and cause that loss of head is large, pump efficiency is not high, are unfavorable for the problem of saving energy and reduce the cost, not only be subject to centrifugal action but also be subject to the characteristics of lift effect for current in the mixed flow pump, a kind of pumping chamber of Volute mixed-flow pump is provided, has improved the efficient of Volute mixed-flow pump.
For achieving the above object, the technical solution used in the present invention: a kind of pumping chamber of Volute mixed-flow pump, it is characterized in that: it comprises stator, spiral case, and described stator is arranged in the described spiral case, and described stator is radial circumference and is distributed in around the mixed-flow pump impeller outer rim.
Described stator is through specialized designs, and totally 12 are distributed in around the mixed-flow pump impeller outer rim, and described stator cross section is that approximate flat is oval, end circular arc projection, the stage casing is straight, the end with in intersegmental circular arc smooth transition.Adjustable lever is established at described stator center, and using adjustable lever can along the stator center rotating, change the angle between described stator center line and described stator and the impeller line of centres; Described stator cross-sectional width is 100:150～200 with the ratio of transition arc radius, and stage casing, described stator cross section thickness is 14:8 with the ratio of end arc diameter.
Beneficial effect: the present invention changes the pumping chamber of Volute mixed-flow pump the assemblying body of spiral case and stator into from traditional spiral case by setting up stator, can improve pump efficiency, has good economic benefit.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.
The pumping chamber of the Volute mixed-flow pump of present embodiment, as shown in Figure 1 and Figure 2, it comprises stator 2 and spiral case 1, current are flowed through after mixed-flow pump impeller 3 work superchargings and are entered in the spiral case 1 behind the stator 2.Conventional volute formula mixed flow pump is collected the guiding fluid discharge tube, liquid kinetic energy is converted to pressure energy by spiral case, only is subject to the situation of centrifugal action for current, and spiral case is a good water-pumping chamber.Also be subject to the lift effect for current in the mixed flow pump, set up stator radially and can be converted into water pressure to the pump discharge circular rector that forms because of lift preferably, thereby can reduce loss of head, improve pump efficiency.
This patent is specially for Volute mixed-flow pump, and is all inapplicable to other pump type (centrifugal pump, guide vane mixed flow pump, axial-flow pump, through-flow pump etc.) and water turbine etc.Traditional Volute mixed-flow pump pumping chamber is only used spiral case, and defectiveness on the water movement principle, this patent have remedied the principle defective after adding stator.Stator is the special parts of a special use, such as the stator number should get 12 uniform, be more excellent as shown in Figure 3 after the stator cross section test.Wherein the water pump outlet pipe diameter is 300mm, and the stator cross-sectional width is 100mm, and the angle between stator center line and described stator and the impeller line of centres is adjustable between the 0-90 degree.As shown in Figure 4.Stator adjustable lever 4 is established at the stator center, and using stator adjustable lever 4 can along the stator center rotating, change the angle between described stator center line and described stator and the impeller line of centres; Described stator cross-sectional width is 100:150～200 with the ratio of transition arc radius, and stage casing, described stator cross section thickness is 14:8 with the ratio of end arc diameter.
Although the present invention with preferred embodiment openly as above; but they and accompanying drawing thereof are not to limit the present invention, anyly are familiar with this skill person, without departing from the spirit and scope of the invention; can make various changes or retouch from working as, equally within protection scope of the present invention.What therefore protection scope of the present invention should be defined with the application's claim protection domain is as the criterion.
