Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

Referring to the drawings, an embodiment of the present invention provides an axial force balance limiting member for a submersible pump, including:

the fixing plate 1, be fixed in the power unit 2 of fixing plate 1 top surface one side, wear to locate the drive shaft 3 in the middle part of power unit 2, the drive shaft 3 is located the one end middle part registrates in the power unit 2 outside and has a bearing 4, and the bearing 4 outside registrates has a fixed pillar 6, and the position that bearing 4 is connected with fixed pillar 6 slides the butt in fixed pillar 6 inner wall, and fixed pillar 6 bottom mounting is in fixing plate 1 top surface.

It should be noted that: the position that 6 inner wall both sides of fixed stay are connected with bearing 4 is equipped with spacing smooth pearl 7 that the ring shape equidistance distributes, spacing slip butt in 6 inner walls of fixed stay and the 4 outer walls of bearing in spacing smooth pearl 7 both ends, spacing annular 8 has been seted up to the position that fixed stay 6 and bearing 4 are connected spacing smooth pearl 7, spacing smooth pearl 7 slip butt in spacing annular 8 inner wall, the rigidity that fixed stay 6 is connected with fixed plate 1 has fixing base 9, spacing smooth pearl 7 is fixed in fixed plate 1 top surface, rotary groove 12 has been seted up to the position that fixed stay 6 is connected with bearing 4, bearing 4 rotates to be connected in rotary groove 12 inboardly, fixing base 9 top surface is seted up the screw rod perforation 11 that the equidistance distributes, fixing screw rod 10 is worn to be equipped with in the screw rod perforation 11 inboard, fixing screw rod 10 other end spiral is worn to locate fixed plate 1 inboardly.
