Description
Technical Field
The invention relates to a method for dismantling a water delivery pipe of a deep-well pump.
Background
The long shaft deep well pump is a vertical single-suction multistage centrifugal pump, its impeller is mounted in the well below the dynamic water level, the power machine is placed on the well, and can be used for driving impeller and making it rotate in the guide shell by means of transmission long shaft, and the water flow can be upwards raised to ground surface by means of water pipe along the flow channel between the guide shell and impeller. The deep-well pump raceway is formed by the shorter water pipe threaded connection of multisection, preventing the screw thread from leaking, need scribble sealed glue in screw thread department during the installation, it is long-lived, the screw thread is killed with sealed glue each other, for dismantling to cause very big difficulty, this is adopting destructive removal mode to demolish the raceway usually, later still need purchase new raceway again and replace original raceway, not only need spend a large amount of funds, still need spend time waiting for new raceway.
Disclosure of Invention
The invention aims to provide a deep-well pump water pipe dismantling method capable of avoiding destructive dismantling, aiming at the defects in the prior art.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
a deep-well pump water pipe dismantling method comprises the following steps: 1) Welding an iron block capable of bearing radial external force on the water conveying pipe; 2) Heating the joint by adopting a flame heating method at 350-450 ℃ to soften the sealant; 3) Applying a radial external force to the iron blocks to enable the threaded connection of the water pipe to generate torsion to rotate and loosen, and rotating to remove the water pipe; 4) Cutting off iron blocks on the water pipe, and polishing the cut part to be flat.
As a further improvement of the above technical solution:
the iron block is triangular, and the stress edge of the iron block is arc-shaped.
In the step 3), when an external force is applied to the iron block, the stress point of the iron block is the middle position of the arc-shaped edge, and the direction of the force faces the opposite angle of the arc-shaped edge.
And reinforcing ribs for supporting the iron blocks are arranged on the upper side and the lower side of each iron block.
The thickness of the iron block is 10cm.
In the step 2), an infrared thermometer is used for detecting the temperature in the heating process.
In the step 2), the joint is heated at a temperature of 400 ℃.
In the step 3), an 18-pound sledge hammer is used to apply an external force to the iron block.
Compared with the prior art, the invention has the advantages that:
when the deep-well pump is dismantled, firstly, an iron block used for bearing radial external force is welded on the water pipe, then, the joint is heated to soften the sealant, then, external force is applied to the iron block, the threaded joint is rotated and loosened, and the water pipe is dismantled in a rotating mode. According to the dismantling method, an external force is applied to the water pipe by means of the iron blocks, the water pipe is not prone to deformation, destructive dismantling is effectively avoided, the dismantled water pipe can be reused only after the iron blocks are cut off and polished, funds for purchasing the water pipe after destructive dismantling are saved, and a large amount of time can be saved.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments or the related art will be briefly introduced below, and it is obvious that the drawings in the following description only relate to some embodiments of the present invention and do not limit the present invention.
Fig. 1 is a schematic view of the connection of the iron blocks and the water pipe of the present invention.
Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a detailed description of the present invention will be made in a non-limiting manner with reference to the accompanying drawings and detailed description.
When the deep-well pump is dismantled, the iron blocks used for bearing radial external force are welded on the water pipe, the joint is heated to soften the sealant, and then external force is applied to the iron blocks, so that the threaded joint is rotated and loosened, and the water pipe is dismantled in a rotating manner.
The method for removing the water delivery pipe of the deep-well pump comprises the following specific steps:
1) As shown in fig. 1, horizontal welding is used for bearing the iron plate 2 that 10cm is thick of radial external force on the raceway 1 that needs demolish, and iron plate 2 iron plate is the triangle-shaped, and its atress limit is the arc, connects more firmly in order to make iron plate 2, all welds the strengthening rib 3 that leans on each other with iron plate 2 in iron plate 2's upper and lower both sides.
2) And (3) heating the threaded joint by adopting a flame heating method at the temperature of 350-450 ℃, and stopping heating after the sealant is softened. The preferred temperature for this embodiment is 400 degrees, and in order to accurately control the temperature of the heating, an infrared thermometer is used to monitor the temperature during heating.
3) An external force is applied to the middle position of the arc-shaped edge of the iron block by using a 18-pound sledge hammer, the direction of the force is towards the opposite angle of the arc-shaped edge of the iron block, so that the threaded connection of the water pipe generates torsion to rotate and loosen, and the water pipe is rotated and disassembled.
4) Cutting off iron blocks on the water pipe, and polishing the cut part to be flat. The polished water delivery pipe can be reused.
According to the method, the arc-shaped edge of the iron block is applied with external force in the dismantling process, the force direction faces the opposite angle of the arc-shaped edge, the external force is applied to the water conveying pipe while the iron block is not easy to fall off, the threaded connection part of the water conveying pipe is loosened, the dismantling method cannot cause deformation of the water conveying pipe, destructive dismantling is effectively avoided, the iron block is cut off after dismantling and can be reused after being polished, the fund for purchasing the water conveying pipe after the destructive dismantling is saved, and a large amount of time can be saved.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
