Description

Technical Field

[0001] The present invention belongs to a calibration device, and particularly relates to a calibration device for the standard clearance value of a deep-well submersible pump. Background Art

[0002] During the in-situ leaching production process, the in-situ leaching pumping borehole plays a crucial role in the entire in-situ leaching activity process. The key to the pumping borehole lies in whether the stable operation of the deep-well submersible pump can be ensured. And the key to whether the deep-well submersible pump can operate stably lies in whether the clearance value of the impeller of the submersible pump is adjusted in place, which requires whether the maintenance tool is reliable and effective.

[0003] Currently, during the maintenance of deep-well submersible pumps in in-situ leaching mines, since the clearance adjustment of the submersible pump is measured manually with a scale, this process takes a long time, and the measured clearance values also vary due to different operators. After the deep-well submersible pump is installed, it often fails to reach the standard clearance value, resulting in serious friction between the impellers, causing overcurrent and wear of the submersible pump motor, and causing rework, which not only increases the installation and maintenance time, but also consumes a large amount of manpower and time, and the work efficiency is low.

[0004] How to quickly and accurately calibrate the standard clearance of the deep-well submersible pump, simplify the intermediate procedures, and improve the maintenance efficiency is an urgent problem to be solved. Summary of the Invention

[0010] In a calibration device for the standard clearance value of a deep-well submersible pump as described above, the submersible pump shaft fixing screw is connected to the submersible pump shaft and the first-stage impeller in the vertical direction and is fixed on the submersible pump maintenance platform.

[0012] A standard clearance value correction device for a deep-well submersible pump as described above, wherein the length of the clearance control rod is 9.53 cm and the length of the clearance clamping post is 4.60 cm.

[0014] The remarkable effect of the present invention is that during the repair process of the deep-well submersible pump, by combining this device with the submersible pump shaft and the first-stage impeller, the adjustment of the standard clearance of the submersible pump and the installation of the impeller can be completed quickly and efficiently, avoiding the difference in the impeller clearance of the submersible pump caused by human operation errors, thus effectively avoiding the wear of the impeller, improving the repair efficiency of the submersible pump, reducing the consumption of the submersible pump impeller, and improving the repair efficiency of the submersible pump.
