Manufacturing technology of vertical long axis semi submersible deep well turbine pump lifting pipe disassembly and assembly tooling

The manufacturing technology of vertical long axis semi submersible deep well turbine pump lifting pipe disassembly and assembly tooling involves the field of vertical long axis semi submersible deep well turbine pump maintenance, specifically referring to a vertical long axis semi submersible deep well turbine pump lifting pipe disassembly and assembly tooling. Including two opposing clamping plates (1), the clamping plate (1) is provided with a circular arc that matches the outer diameter of the lifting water pipe. There are connecting holes (1.2) on both sides of the circular arc of the clamping plate (1). The two clamping plates (1) form a clamping part for the lifting water pipe through fasteners and the circular arc. Two opposing supporting base plates (2) are detachably connected below the two clamping plates (1), and the contact surface between the supporting base plates (2) is provided with a bayonet for the lifting water pipe to pass through. The beneficial effects of this technology are: it has a simple structure, easy installation, and can quickly disassemble and assemble the lifting pipes of the vertical long shaft semi submersible deep well turbine pump at all levels, reducing maintenance time, lowering maintenance costs, ensuring safe and reliable disassembly and assembly operations, and effectively preventing parts from falling into the well during the maintenance process.

Technical Introduction

At present, in the production process of steel rolling mills, the vertical long shaft semi submersible deep well turbine pump unit is responsible for the water supply and cooling of MULPIC, a multifunctional intermittent acceleration cooling system. In general, for maintenance and disassembly, it is necessary to lift it out as a whole and place it horizontally on the ground for easy disassembly and assembly. However, due to the insufficient space in the pump room and the compact arrangement of the long shaft deep well pump unit, it cannot be horizontally arranged during maintenance and disassembly. When disassembling and assembling, the lifting equipment can only be used to vertically disassemble and assemble the lifting water pipe section by section at the wellhead. A slight mistake in operation can easily cause its components to fall into the well and be unable to be removed, which will damage or even directly scrap other equipment or pump bodies in the well, and also affect the normal operation of other pumps, increasing the difficulty and risk of maintenance operations. The economic losses caused by chain reactions cannot be estimated, and it is an urgent problem that technical personnel in this field need to solve.

Technical implementation ideas

This technology provides a vertical long axis semi submersible deep well turbine pump lifting pipe disassembly and assembly fixture to solve the above technical problems, which facilitates the disassembly and assembly of lifting pipes at all levels of the vertical long axis semi submersible deep well turbine pump, and can effectively prevent adverse effects caused by parts falling into the well during maintenance. This technology is achieved through the following technical solution: a vertical long axis semi submersible deep well turbine pump lifting pipe disassembly and assembly fixture, comprising two opposing clamping plates, wherein the clamping plates are provided with circular arcs adapted to the outer diameter of the lifting pipe, and connection holes are opened on both sides of the circular arc of the clamping plate. The two clamping plates form a clamping part for the lifting pipe through fasteners and the circular arc. Two opposing supporting base plates are detachably connected below the two clamping plates, and the contact surface between the supporting base plates is provided with a clamp for the lifting pipe to pass through. The clamp can facilitate the safe and quick placement of the supporting base plate at the long axis deep well wellhead and position it on the pipe wall of the lifting pipe. As a preferred option, the top surface of the supporting base plate is also fixedly connected with positioning rods, and the two ends of the bottom surface of the clamp plate are provided with positioning openings corresponding to the supporting base plate, which are connected to the positioning rods. As a preferred option, the cross-section of the positioning rod is circular or rectangular.
