8. A method of operating a device for dynamic and static balancing of an impeller for a submersible pump for a well according to claim 7, characterized in that, Firstly, the impeller of the well submersible pump is placed above the test platform body (1), then according to the inner diameter of the center hole of the impeller, the specified type of clamping disc (2012) is taken out, then the threaded cover (2011) is screwed on the threaded head (2010), then the first motor (202) is started to make the first gear (203) rotate, then under the action of the rack (206), the slider (205) on the moving plate (204) moves along the T-shaped sliding groove (201) to approach each other, so that the clamping disc (2012) on the threaded cover (2011) clamps the impeller of the well submersible pump, and when the impeller of the well submersible pump is clamped, the moving rod (209) moves along the rotating sleeve (207), and the spring (208) is compressed, which can increase the clamping range and clamp different types of impellers. When the balance test is finished, the first motor (202) is started to reverse the first gear (203), then under the action of the rack (206), the slider (205) on the moving plate (204) resets along the T-shaped sliding groove (201), so that the clamping disc (2012) on the threaded cover (2011) is separated from the impeller, then under the action of the spring (208), the moving rod (209) resets along the rotating sleeve (207). When static balance test is needed, first clamp the impeller, then start the air cylinder (304) to move the pulley (305), then under the action of the annular sliding groove (308), the limiting hole (307) on the third gear (306) moves along the limiting shaft (303) to engage the third gear (306) with the second gear (301). At this time, the second motor (302) is started to slowly rotate the limiting shaft (303), and under the action of the limiting hole (307), the rotating sleeve (207) on the third gear (306) rotates to a specified angle. At this time, the air cylinder (304) is started to continue moving the pulley (305), then under the action of the annular sliding groove (308), the third gear (306) is disengaged from the second gear (301). If the gravity distribution of the impeller is uneven, the rotating sleeve (207) is driven to rotate by the impeller, so that the center of gravity of the impeller rotates to the directly below the rotating sleeve (207), then the air cylinder (304) is continued to start to move the connecting plate (4010) in a large range, then drive the fourth gear (405) to move by the toothed belt (406), so that the fourth gear (405) rotates along the connecting frame (404) on the support rod (403), thereby driving the conveyor belt (407) to move along the placement arc plate (402) on the support plate (401), so that the magnetic counterweight (409) in the limiting port (408) is separated from the placement arc plate (402), and then falls onto the impeller. Under the magnetic action of the magnetic counterweight (409), the magnetic counterweight (409) is adsorbed to the top of the impeller, thereby adjusting the weight of the impeller.Make the third gear (306) to make a wide range of movement, so that the connecting rod (7) on the mark strip (8) mark the impeller starting position, and then repeat the above operation four to five times, so that the impeller can keep balance at different angles, then add the specified weight of oil sludge to the impeller with the magnetic counterweight (409), so that the impeller keeps balance, when you need to test dynamic balance, start the air cylinder (304) to make the pulley (305) move, then under the action of the annular slide (308), the limiting hole (307) on the third gear (306) moves along the limiting shaft (303), so that the third gear (306) engages with the second gear (301), at this time, start the second motor (302) to make the limiting shaft (303) rotate quickly, under the action of the limiting hole (307), the rotating sleeve (207) on the third gear (306) drives the impeller to rotate quickly, then through the dynamic balance detection probe (6) on the support frame (5), the rotating impeller is detected, the detected unbalance and the weight position are transmitted to the computer for display, then the impeller is corrected.
