The magnetic chuck needed to be adjusted and re-fixed. The magnetic chuck device needed to be removed during the adjustment of the wheel. The alignment process was cumbersome and the alignment accuracy was poor. Utility Model Content

[0022] Pump wheel alignment frame, such as Figure 1 and Figure 2As shown, the pump wheel includes a pump shaft 1, a pump wheel 2 at the end of the pump shaft 1, a motor shaft 3 and a motor wheel 4 at the end of the motor shaft 3. The pump wheel 2 and the motor wheel 4 are connected by a rigid coupling, so the wheel installation accuracy is required to be high.

[0023] The pump end clamp 5 is encircled on the pump shaft 1, and the motor end clamp 6 is encircled on the motor shaft 3. Compared with the traditional magnetic installation, the stability of the alignment frame installation is improved, and the problem of deviation caused by the offset of the alignment frame is avoided. Therefore, the dial indicator can be accurately arranged, the wheel can be accurately aligned, and the accuracy of the pump to wheel alignment is guaranteed.
[0024] By setting the pump end clamp 5 and the pump end dial indicator frame 8 on the pump shaft 1 side, and the motor end clamp 6 and the motor end dial indicator frame 10 on the motor shaft 3 side, dial indicators can be set on the pump shaft 1 side and the motor shaft 3 side at the same time, and the two sets of data can be measured at the same time. The two sets of data can be compared with each other, which is beneficial to improve the alignment accuracy and alignment speed.
[0025] In order to protect the pump shaft 1 and prevent the pump end clamp 5 from damaging the pump shaft 1, the inner wall of the pump end clamp 5 is covered with an isolation gasket 13. In order to protect the motor shaft 3 and prevent the motor end clamp 6 from damaging the motor shaft 3, the inner wall of the motor end clamp 6 is covered with an isolation gasket 13.
[0026] In order to facilitate the assembly of the pump end clamp 5 to the pump shaft, Figure 3As shown, the pump end clamp 5 includes an upper half clamp 5A and a lower half clamp 5B of the pump end that are arranged opposite to each other.

The width of the pump end clamp 5 should not be too wide, generally about 30 mm. The bending arc of the upper half clamp 5A and the lower half clamp 5B of the pump end should be less than π, so as to ensure that the pump end clamp 5 can be firmly fixed on the pump shaft.
[0027] In order to facilitate the assembly of the motor end clamp 6 to the motor shaft 3, as shown in FIG. Figure 4 As shown, the motor end clamp 6 includes an upper half clamp 6A and a lower half clamp 6B of the motor end that are arranged opposite to each other, and the upper half clamp 6A and the lower half clamp 6B of the motor end are both Ω-shaped, including an arc-shaped motor end embracing section 6D adapted to the motor shaft 3 and motor end ear plates 6E extending outwardly on both sides of the motor end embracing section 6D, and the motor end ear plates 6E of the upper half clamp 6A and the lower half clamp 6B of the motor end are connected via a motor end connecting bolt assembly 6C. The width of the motor end clamp 6 should not be too wide, generally about 30 mm. The bending curvature of the upper half clamp 6A and the lower half clamp 6B of the motor end should be less than π, so as to ensure that the motor end clamp 6 can be firmly fixed on the motor shaft.
