Hold linkage section, the upper location shaft shoulder, motor linkage section, the lower location shaft shoulder and lower bearing linkage section, the union joint of described flat shape
It is positioned at the end of upper bearing (metal) linkage section.
In the attachment structure of above-mentioned a kind of well immersible pump pump shaft, the top ends of described impeller axle is provided with spacing
Groove.
In the attachment structure of above-mentioned a kind of well immersible pump pump shaft, the diameter of described upper bearing (metal) linkage section is more than leaf
The circumscribed diameter of wheel shaft, the external diameter of described shaft coupling is more than the diameter of upper bearing (metal) linkage section.
In above-mentioned a kind of deep well pump pump shaft, the diameter of the described upper location shaft shoulder is straight more than upper bearing (metal) linkage section
Footpath, the diameter of the described upper location shaft shoulder is less than the diameter of motor linkage section.The setting of the upper location shaft shoulder of this dimensional standard is opened
Arrive the effect of spacing upper bearing (metal).
In above-mentioned a kind of deep well pump pump shaft, the diameter of the described lower location shaft shoulder is straight more than lower bearing linkage section
Footpath, the diameter of the described lower location shaft shoulder is less than the diameter of motor linkage section.The setting of the lower location shaft shoulder of this dimensional standard is opened
Arrive the effect of spacing lower bearing.
Compared with prior art, this well impeller axle in the attachment structure of immersible pump pump shaft is joined by flat with motor shaft
Axial organ is connected, and has offered flat groove and positive six limits that the union joint for flat shape is installed with hexagon impeller axle in shaft coupling respectively
Shape hole so that its contact area connected is bigger, weares and teares and diminish in rotation process, and stability is higher.
