Description

Technical Field

[0001] The utility model relates to the technical field of clamping impellers of submerged brine pumps, in particular to a detection fixture for impellers of submerged brine pumps. Background Art

[0002] The impeller of a submersible brine pump is a core component used in submersible brine pumps. It is responsible for drawing liquid or gas from the inlet and pushing it to the outlet. Different types of submersible brine pumps have different impeller designs and working principles. Common impeller types of submersible brine pumps are centrifugal impellers and axial flow impellers. Centrifugal impellers can push fluid to the outlet through the action of centrifugal force, which is suitable for applications with smaller flow and higher head; axial flow impellers can push a larger volume of fluid along the axial direction, which is suitable for applications with large flow and smaller head.

[0003] The working conditions of the impeller of a submersible brine pump usually involve liquid temperature, pressure, immersion depth, etc. The tolerance and applicable range of the impeller need to be determined according to the actual situation to ensure its normal operation and life. Therefore, we generally need to detect whether the impeller meets the working conditions. Usually, a detection device is required. Generally, it is clamped by a clamp. When clamping it, due to the different heights of the central axis tubes of different impellers, the corresponding fixed clamp seat spacing will also be different, and generally this type of fixed clamp can only clamp the central axis tube of the impeller to limit the position; however, when the impeller is subjected to rotation simulation detection, the clamping between the fixed clamp and the impeller is prone to loosening, resulting in the rotating fixed clamp being unable to drive the impeller to be tested to rotate stably, affecting the data accuracy when the impeller is detected; therefore, the above problems need to be improved.
