The pump can timely adjust the vane angle according to the environment of the operating condition in each period to optimize the delivery lift, flow rate and current of the water pump, so the water pump can be operated in a high-efficiency area, and the utility model is suitable to water pumps with various changes of delivery lift.
Description
[technical field]
The utility model relates to a kind of axial-flow pump, belongs to the fluid machinery technical field.
[background technique]
Existing axial-flow pump has following defective:
1. water pump does not have controlling mechanism, and the fixing back of blade installation is just inactive, and blade angle can not be regulated, and loses efficient district when axial-flow pump is moved under off-design behaviour, is not suitable for different lift occasions and uses, and therefore, its utilization efficiency is low; 2. when pumping lift is higher because can not the adjusting vane angle, this axial-flow pump can't normally be moved in higher, certain range of lift, have only by forced-stopping machine.Vast medium and small axial-flow pump user, urgent wish to have a kind ofly can to improve the utilization efficiency of axial-flow pump, reach the purpose that the water pump operation lift could both efficiently be moved and improve to a pump various working according to the water pump of different lift adjusting vane angles.
[summary of the invention]
For overcoming the above-mentioned defective of existing axial-flow pump, the utility model provides a kind of can regulate axial-flow pump entirely according to different lift adjusting vane angles, with utilization efficiency that improves axial-flow pump and the operation lift that improves water pump, satisfies the needs of different use occasions.
For solving its technical problem, the technical solution adopted in the utility model is: the utility model comprises pump shaft, pump shaft pull bar, diffuser, loudspeaker, impeller base, blade, rocking arm, connecting rod, connecting rod base, guide holder, draw-bar seat, bend pipe and rigid coupling.Be characterized in: 1. pump shaft is to be provided with a pull bar in this hollow shaft of hollow shaft, the upper end of pull bar is stretched out and is connected with pump housing speed regulator outward, the lower end of pull bar is connected with draw-bar seat, and four connecting rod bases are housed on the draw-bar seat, and connecting rod base is connected blade by connecting rod with rocking arm; Stop nut also is installed on guide holder, and this stop nut control blade rotates between+6 °～-6 °.2. pump shaft is a hollow shaft, and pump shaft is by the supporting of two on bend pipe and diffuser picture glue bearings, and the pump shaft upper end is passed filler and closed seat and be connected with rigid coupling, is connected with the external agency of pump by rigid coupling again; The lower end of pump shaft is provided with land, and land is connected with impeller base, and four blades are housed on the impeller base, and seal closure and water diversing head are equipped with in the lower end of impeller base; The upper end of impeller base and blade, seal closure all are equipped with rubber seal.3. four connecting rod bases are housed on the draw-bar seat, and connecting rod base is connected with four blades with rocking arm by connecting rod, and connecting rod base is locked on the draw-bar seat with nut, can carry out synchronization regulation to blade by the nut on the connecting rod.
The beneficial effects of the utility model are: because pump shaft of the present utility model is a hollow shaft, pull bar in the hollow shaft is connected with draw-bar seat, when pull bar moves up and down, blade can be rotated between-10 °～+ 10 ° at-6 °～+ 6 ° axial-flow pump by connecting rod base, connecting rod and rocking arm.The user can make lift, flow, the electric current of water pump at one's best according to the work condition environment in each period adjusting vane angle at any time; Can seek out simultaneously the efficient district of water pump, overcome the drawback that 700～1400mm bore axial-flow pump is in the past lost efficient district easily, also can overcome outer stream stage simultaneously when higher, water pump will be by the passive situation of forced-stopping machine.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Among the figure: 1 rigid coupling, 2 Glands, 3 hose couplings, 4 filler cassette holders, 5 rubber bush bearings, 6 bend pipes, 7 pump shafts, 9 lands, 10 impeller bases, 11 blades, 12 draw-bar seats, 13 seal closures, 14 water diversing heads, 15 loudspeaker, 16 guide holders, 17 connecting rod bases, 18 connecting rods, 19 rocking arms, 20 pump shaft pull bars.
