Concentricity measurement device for lifting water pipe of deep well suspended semi submersible vertical turbine pump

The concentricity measurement device for the lifting pipe of a suspended semi submersible vertical turbine pump in a deep well consists of a lifting pipe (1), a measuring plate (2), a standard ring (3), and an installation foundation (4). Multiple installation foundations (4) are made by grouting at appropriate positions at different depths below the installation wellhead using a water pump installation wellhead suspension line. The water pump installation wellhead is horizontal and concentric with the installation foundation (4); Install the standard ring (3) onto the installation foundation (4), install the water pump, and ensure that the water pump is installed in the center of the inlet by installing bolts on the wellhead plane. This technical method is applicable to various deep well suspended semi submersible vertical turbine pumps, with a unique structure, simple and intuitive measurement.

Technical requirements: 1. A device for measuring the concentricity of the lifting pipe of a suspended semi submersible vertical turbine pump used in deep wells, consisting of a lifting pipe (1) of the deep well pump, a measuring plate (2), a standard ring (3), and an installation foundation (4). The device is characterized in that multiple installation foundations (4) are made by grouting at appropriate positions at different depths below the installation well through a water pump installation wellhead suspension line, and the water pump installation well is horizontal and concentric with the installation foundation (4); Install the standard ring (3) onto the installation foundation (4) and install the water pump properly; Install the measuring plate (2) onto the entire convex platform of the lifting pipe (1) of the deep well pump and measure the distance from the standard ring (3) to the top of the circular arc of the measuring plate (2); Ensure that the water pump is installed in the center of the inlet by installing bolts on the wellhead plane.
