Abstract
The utility model provides a kind of connecting shaft for immersible pump, including connection shaft body 1, and the one end for connecting shaft body is spherical connector, and the other end for connecting shaft body is column connector；Spherical connector, column connector are that arc variable diameter is connect with connection shaft body；Do the processing of arc variable diameter in the outer end of column connector.A kind of the technical problem to be solved by the present invention is to provide wearabilities good, good corrosion resistance, structural stability is good and can bear the coupling spindle for immersible pump of active force for a long time.
Description
Technical field
The utility model relates to a kind of mechanical fitting, especially a kind of coupling spindle for immersible pump.
Background technique
A kind of water process tool that purposes is very extensive of immersible pump.Immersible pump its work unlike common water pumper
Under water, and water pumper works on the ground mostly；It, must be hydraulically full in suction line and pump before immersible pump turn on pump；After turn on pump,
Impeller high speed rotation, liquid in immersible pump rotate together with blade, under the influence of centrifugal force, fly away from impeller and penetrate outward
Out, the liquid of injection speed in pump case diffuser casing is gradually slack-off.
The defects of generally existing service life of the immersible pump of market is short at present, and accessory is easy to damage, especially motor and water pump
Between coupling spindle easily there are the failures such as serious wear or fracture when working long hours.
Utility model content
A kind of the technical problem to be solved by the present invention is to provide wearabilities good, good corrosion resistance, structural stability be good,
And the coupling spindle for immersible pump of active force can be born for a long time.
In order to solve the above technical problems, the utility model provides a kind of coupling spindle for immersible pump, comprising: including connection
Spindle ontology, one end of the connection shaft body are spherical connector, and the other end of the connection shaft body is column company
Connector；The spherical connector, column connector are that arc variable diameter is connect with the connection shaft body.
Preferably, as further Optimal improvements, the connection shaft body, spherical connector and column connector
Material is 316 stainless steels.
Preferably, as further Optimal improvements, the connection shaft body, spherical connector and column connector
Material is Monel K500 alloy.
Preferably, as further Optimal improvements, the connection shaft body, spherical connector and column connector are all
It is made of investment precision casting technology.
Preferably, as further Optimal improvements, the connection shaft body, spherical connector and column connector
Do phosphorating treatment in outer surface.
Preferably, as further Optimal improvements, the processing of arc variable diameter is done in the outer end of the column connector.
Compared with prior art, the utility model has the advantages that: the setting of spherical connector and column connector, Ke Yigeng
Good connection motor and water pump；Arc variable diameter design can preferably adapt to the bearing of motor and water pump；Coupling spindle uses 316
Stainless steel or Monel K500 alloy, can make the intensity of the coupling spindle and corrosion resistance outstanding, extend and use the longevity
Life；Using coupling spindle made of investment precision casting technology, phosphorating treatment can prevent metal to be corroded to a certain extent.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the overall structure diagrammatic cross-sectional view of the utility model.
Specific embodiment
To enable the above objects, features, and advantages of the utility model to be clearer and more comprehensible, the use of the utility model hereafter
In the coupling spindle of immersible pump, it will cooperate appended relevant drawings with preferred embodiment, elaborate.
In the description of the present invention, it should be noted that term " on ", "lower", "vertical", "horizontal", "inner",
The orientation or positional relationship of the instructions such as "outside" is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing this reality
It is described with novel with simplified, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific
Orientation construction and operation, therefore should not be understood as limiting the present invention.
The coupling spindle for immersible pump of the present embodiment, as shown in Figure 1, include connection shaft body 1, connection shaft body 1
One end is spherical connector 2, and the other end of connection shaft body 1 is column connector 3；Spherical connector 2, column connector 3 with
Couple shaft body 1 for the connection of arc variable diameter；Do the processing of arc variable diameter in the outer end of column connector 3.
Using coupling spindle made of 316 stainless steels or Monel K500 alloy, intensity is preferable, and corrosion resistance is preferable；And
Good operating stability after connection motor and water pump, is hardly damaged；The anticorrosive of coupling spindle can be further enhanced after phosphorating treatment
Performance.
In conclusion the utility model is by spherical connector, column connector, arc variable diameter design theory, 316 is stainless
Steel, Monel K500 alloy cross investment precision casting technology, and the integrated uses such as phosphorating treatment are used for the coupling spindle of immersible pump to this
On, it is not mentioned in existing field, and the utilization of the relevant technologies, the coupling spindle is enabled to have lot of advantages, such as wearability
Well, corrosion resistance is good, intensity is high, stability is good etc..Therefore, the utility model has significant progress.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
