Abstract
The utility model belongs to the field of mechanical devices and particularly relates to a vertical-type mixed flow pump with an extractable rotor. The vertical-type mixed flow pump comprises an outer connection pipe, an inner connection pipe, a rotating shaft, an impeller and a water-sucking taper pipe, wherein the water-sucking taper pipe is arranged at the bottom end of the outer connection pipe; the inner connection pipe is fixed in the outer connection pipe; the rotating shaft is arranged in the inner connection pipe, the impeller is arranged at the bottom end of the rotating shaft; and a water outlet is arranged on the side wall of the outer connection pipe. With the adoption of the vertical-type mixed flow pump with the extractable rotor, a flow deflector at the outlet of a conventional mixed flow pump is removed, so that indirect influence of impact force of liquid on the inner connection pipe and the rotating shaft can be reduced, the deformation of the inner connection pipe is avoided, and the service life of the rotating shaft is prolonged; moreover, under normal work state, the liquid can be filled in liquid channels of the inner connection pipe and the outer connection pipe and flows out automatically from the water outlet under the effect of pressure, therefore, the detachment of the flow deflector not only cannot influence the normal work of the mixed flow pump, but also leads the mixed flow pump to have simpler structure and reduces the production cost.
Description
Technical field
The utility model relates to the vertical mixed flow pump of a kind of rotor drawable type, belongs to the mechanical device field.
Background technique
Traditional vertical mixed flow pump of rotor drawable type generally includes inner connecting tube, externally connected pipe, rotor part, guide plate, impeller and suction Taper Pipe, and guide plate is positioned at the water outlet place of externally connected pipe, and rotor part is arranged in the inner connecting tube; During maintenance, need not dismantle externally connected pipe, directly rotor extracted out; Just can keep in repair rotor part, bearing etc., easy to maintenance, but pump housing when work; Liquid can change the flow direction under the effect of guide plate, according to the principle of active force and reaction force, liquid also can be given guide plate one impact force; The inner connecting tube that can cause being connected with guide plate produces distortion; Thereby the working life of remote-effects inner connecting tube rotor parts, and under the normal state, liquid can be filled in the fluid passage of inner connecting tube and externally connected pipe; Whether the guide plate setting can not influence liquid flows out from water outlet, so the setting of guide plate has also increased cost of production.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of simple in structure, vertical mixed flow pump of rotor drawable type of reducing cost and increasing the service life is provided.
The utility model solves the technological scheme that its technical problem adopted: the vertical mixed flow pump of described rotor drawable type; It is characterized in that: comprise externally connected pipe, inner connecting tube, rotating shaft, impeller and suction Taper Pipe; The suction Taper Pipe is installed in the externally connected pipe bottom, and inner connecting tube is fixed in the externally connected pipe, and rotating shaft is installed in the inner connecting tube; Impeller is installed in the rotating shaft bottom, and the sidewall of externally connected pipe is provided with water outlet.
During mixed flow pump work; By the suction Taper Pipe liquid is sucked in the externally connected pipe; Impeller gets into the fluid passage that the liquid in the externally connected pipe makes progress and flows and be full of externally connected pipe and inner connecting tube under the action of the centrifugal with the rotating shaft high-speed rotation, and liquid finally flows out from water outlet under pressure.
The beneficial effect that the utility model had is:
The vertical mixed flow pump of this rotor drawable type is removed the guide plate at traditional mixed flow pump water outlet place; Can reduce the remote-effects of hydraulic shock power, prevent the inner connecting tube distortion, prolong the working life of rotating shaft inner connecting tube and rotating shaft; And mixed flow pump in normal operation; Liquid can fill up the fluid passage of inner connecting tube and externally connected pipe, and liquid flows out from water outlet under pressure automatically, therefore removes the proper functioning that guide plate not only can not influence mixed flow pump; Make that also the mixed flow pump structure is simpler, reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, externally connected pipe; 2, inner connecting tube; 3, water outlet; 4, fluid passage; 5, rotating shaft; 6, impeller; 7, suction Taper Pipe.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The vertical mixed flow pump of rotor drawable type comprises externally connected pipe 1, inner connecting tube 2, rotating shaft 5, impeller 6 and suction Taper Pipe 7; Suction Taper Pipe 7 is installed in externally connected pipe 1 bottom, and inner connecting tube 2 is fixed in the externally connected pipe 1, and rotating shaft 5 is installed in the inner connecting tube 2; Impeller 6 is installed in rotating shaft 5 bottoms, and the sidewall of externally connected pipe 1 is provided with water outlet 3.
During mixed flow pump work; By suction Taper Pipe 7 liquid is sucked in the externally connected pipe 1; Impeller 6 gets into the fluid passage 4 that the liquid in the externally connected pipe 1 makes progress and flows and be full of externally connected pipe 2 and inner connecting tube 3 under the action of the centrifugal with rotating shaft 5 high-speed rotation, and liquid flows out from water outlet 3 under pressure automatically.Compare traditional vertical mixed flow pump of rotor drawable type, this mixed flow pump structure is simpler, and cost of production reduces greatly, and can reduce the remote-effects of hydraulic shock power to inner connecting tube and rotating shaft, prevents the inner connecting tube distortion, has prolonged the working life of rotating shaft.
