Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a special tool for manually removing the weight of an impeller in a dynamic balance manner comprises a dynamic balance washer 1, a positioning assembly 2 and an upper pressure head assembly 3, wherein the positioning assembly 2 and the upper pressure head assembly 3 are detachably arranged, the dynamic balance washer 1 is sleeved between the positioning assembly 2 and the upper pressure head assembly 3, and the dynamic balance washer is used for fixing the impeller;

the middle of the dynamic balance washer 1 is provided with a through hole 11, the dynamic balance washer 1 positioned on the periphery of the through hole 11 is provided with a magnetic attraction ring 12, the dynamic balance washer 1 positioned on the periphery of the magnetic attraction ring 12 is provided with a circle of balance holes 13, the periphery of the dynamic balance washer 1 is also provided with an annular handle 14, and the annular handle 14 and the dynamic balance washer 1 are connected with each other through a connecting rod 141.

In this embodiment, the positioning assembly 2 includes a positioning block 21, the diameter of the positioning block is slightly larger than the diameter of the shaft hole of the impeller, a spindle 22 is disposed above the positioning block 21, and an installation rod 23 is disposed below the positioning block 21.

In this embodiment, go up pressure head subassembly 3 and include pressure head 31, it is equipped with stopper 32 to go up pressure head 31 below, the diameter of stopper slightly is greater than the shaft hole diameter of impeller, stopper 32 below is equipped with connecting axle 33, and the diameter size of connecting axle and the shaft hole diameter size phase-match of impeller, impeller can remove or rotate on the connecting axle, slot 331 has been seted up to connecting axle 33 bottom, slot 331 and dabber 22 phase-match.

In this embodiment, the assembly method of the impeller and impeller dynamic balance manual de-weighting special tool is as follows:

firstly, fixing the mounting rod on a workbench, and mounting the positioning assembly on the workbench;
