Abstract
The utility model relates to a kind of DC water pump more particularly to a kind of DC water pump impellers, belong to agricultural machinery applied technical field.A kind of DC water pump impeller, including blade, motor shaft and impeller intake are equipped with threaded hole at impeller intake, and motor shaft is fixed at impeller intake by threaded hole, and the diameter of threaded hole is greater than the diameter of impeller intake, and motor shaft is equipped with boss.Impeller intake is two.Boss is right angle boss.The utility model has the beneficial effects that reducing impeller intake at a distance from motor shaft, increases the flow at impeller suction, increase the rigidity of motor shaft, solve the problems, such as that motor shaft need to lengthen overstriking.
Description
Technical field
The utility model relates to a kind of DC water pump more particularly to a kind of DC water pump impellers, belong to agricultural machinery and answer
Use technical field.
Background technique
In daily agricultural production, immersible pump is exchanged, lift is low, and flow is big, is generally used in flat-bottomed land.Due to mountain area
The terraced fields of hilly country do not have indirect current, generally carry out soil watering using direct-current power supply immersible pump, but direct current is dived under water
Pump lift is lower, and flow is smaller, and peasant is inconvenient to use, and inefficiency.It, can only be latent using direct current but since condition limits
Water pump.The lift and flow of D. C. submersible pump are not achieved, and lift is low, and the terraced fields limited height system of watering, flow is small, watering when
Between greatly increase.Impeller face is longer on the right side of the positional distance of Traditional DC motor for submerged pump axis connection blackout nut, so to add
Thick motor shaft is used to guarantee rigidity.And the blackout nut at impeller suction can reduce the area of water sucking mouth, will cause flow
Decline.Therefore, the improvement of D. C. submersible pump is extremely urgent.
Utility model content
The utility model in view of the above-mentioned deficiencies in the prior art, provides a kind of DC water pump impeller.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of DC water pump impeller, including blade, motor shaft and impeller intake are equipped with threaded hole at impeller intake,
Motor shaft is fixed at impeller intake by threaded hole, and the diameter of threaded hole is greater than the diameter of impeller intake, on motor shaft
Equipped with boss.
Preferably, impeller intake is two.
Preferably, boss is right angle boss.
Compared with prior art, the utility model has the beneficial effects that reducing impeller intake at a distance from motor shaft, increase
The flow of large impeller water sucking mouth increases the rigidity of motor shaft, solves the problems, such as that motor shaft need to lengthen overstriking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1, blade in the figure；2, motor shaft；3, impeller intake；4, threaded hole；5, boss.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Such as Fig. 1, a kind of DC water pump impeller, including blade 1, motor shaft 2 and impeller intake 3 are set at impeller intake 3
There is threaded hole 4, motor shaft 2 is fixed at impeller intake 3 by threaded hole 4, and the diameter of threaded hole 4 is greater than impeller intake 3
Diameter, motor shaft 2 be equipped with symmetrical boss 5.Impeller intake 3 is two.Boss 5 is right angle boss.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
