Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and in particular to a high-efficiency workbench for assembling a dry submersible motor. Background Technology

[0002] Axial flow submersible pumps are suitable for low-head pumping stations. They have good hydraulic performance, smooth flow channels, high efficiency, compact structure, and low engineering investment.

[0003] A submersible axial flow pump connects a dry-type submersible motor to the pump body, with the impeller mounted on the motor shaft. The dry-type submersible motor is a three-phase AC asynchronous motor. Current drawn from a three-phase power supply generates a rotating magnetic field in the stator windings of the dry-type submersible motor. This rotating magnetic field cuts the squirrel cage bars of the rotor, inducing current in the bars and generating electromagnetic torque. This electromagnetic torque drives the rotor and the impeller mounted on the rotor shaft to rotate, thus achieving the conversion of electromagnetic power into water power. The quality of the dry-type submersible motor assembly directly affects the performance of the axial flow pump; therefore, it is essential to assemble the entire dry-type submersible motor using a high-efficiency workbench. Summary of the Invention

[0004] The present invention aims to provide a high-efficiency workbench for assembling a dry submersible motor.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A high-efficiency workbench for assembling a dry submersible motor includes a main frame, a workbench panel, and a movable V-shaped iron. The workbench panel is fixed to the top of the main frame, and a rubber plate is laid on the workbench panel. Four through slots are opened on the workbench panel, with every two through slots being coaxial and opposite through slots being parallel to each other. The movable V-shaped iron is fixed to each through slot by fastening bolts. A rubber plate for the working surface of the V-shaped iron is provided on the upper support side of the movable V-shaped iron. Upper toolboxes are provided on the upper part of both sides of the main frame, and the upper door of the upper toolbox is hinged to the outer end face of the upper toolbox. Lower toolboxes are provided on the lower part of both sides of the main frame, and the lower door of the lower toolbox is hinged to the outer end face of the lower toolbox.

[0007] The upper door of the toolbox is hinged to the upper toolbox via hinge I, and the lower door of the toolbox is hinged to the lower toolbox via hinge II.

[0008] The toolbox upper and lower doors are recessed, with a perimeter height of 20mm.

[0009] The movable V-shaped iron has a bottom plate hole on its lower support side. Fastening bolts pass through the bottom plate hole and through groove to connect the movable V-shaped iron, and the fastening bolts are fastened by Φ12 flat washers and M12 hexagonal nuts.

[0010] The movable V-shaped iron has a support column connecting its upper and lower support sides.

[0011] The maximum opening angle of the upper and lower doors of the toolbox is 90°, until it reaches a horizontal position.

[0012] The beneficial effects of this utility model are: the utility model has a reasonable structure and is easy to use. Using this workbench for the assembly of dry submersible motors can improve the work efficiency of dry submersible motor assembly, ensure high operational safety, improve the working environment, and the upper and lower doors of the toolbox can be placed in a horizontal position as a tray.

[0017] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] A high-efficiency workbench for assembling a dry submersible motor includes a main frame 8, a workbench panel 1, and a movable V-shaped iron 2. The workbench panel 1 is fixed to the top of the main frame 8. A workbench surface rubber plate 7 is laid on the workbench panel 1. Four through slots 13 are opened on the workbench panel 1. Every two through slots 13 are coaxial, and opposite through slots 13 are parallel to each other. The movable V-shaped iron 2 is fixed at each through slot 13 by fastening bolts 3. A V-shaped iron working surface rubber plate 6 is provided on the upper support side of the movable V-shaped iron 2. Upper toolboxes are provided on the upper part of both sides of the main frame 8. The outer end face of the upper toolbox is hinged to the upper toolbox door 9. Lower toolboxes are provided on the lower part of both sides of the main frame 8. The outer end face of the lower toolbox is hinged to the lower toolbox door 10.

[0020] The upper door 9 of the toolbox is hinged to the upper toolbox via hinge I11, and the lower door 10 of the toolbox is hinged to the lower toolbox via hinge II12. The included angle between the two sides of hinge I11 and hinge II12 is between 0° and 90°.

[0021] The toolbox upper door 9 and toolbox lower door 10 are in the shape of a groove, and the height of the groove is 20mm.

[0022] The movable V-shaped iron 2 has a bottom plate hole 14 on its lower support side. The fastening bolt 3 passes through the bottom plate hole 14 and the through groove 13 to connect the movable V-shaped iron 2, and is fastened by the Φ12 flat washer 4 and the M12 hexagonal nut 5.

[0023] The movable V-shaped iron 2 has a support column connecting its upper and lower support sides.

[0024] The maximum opening angle of the toolbox upper door 9 and the toolbox lower door 10 is 90°, until they reach a horizontal position.

[0025] In operation, the stator of the dry-type submersible motor is horizontally placed on the movable V-shaped irons 2 mounted on the workbench panel 1. The spacing between the movable V-shaped irons 2 is adjusted according to the outer diameter of the dry-type submersible motor, allowing stators of different diameters to be placed within the movable V-shaped irons 2. Four movable V-shaped irons 2 are secured with fastening bolts 3, which pass through slots 13 from the bottom of the workbench panel 1 and through holes 14 in the bottom plate of the movable V-shaped irons 2. The bolts 3 are tightened using Φ12 flat washers 4 and M12 hexagonal nuts 5. The bottom of the stator's outer diameter is always kept 10mm away from the workbench panel 1, ensuring the dry-type submersible motor stator remains stable within the movable V-shaped irons 2. The stator diameter of the dry-type submersible motor ranges from Φ300mm to Φ1200mm. The toolboxes on both sides of the workbench are opened and positioned horizontally as trays. Tools and accessories needed for motor assembly are placed on these trays for easy access. Each component is then assembled with the dry-type submersible motor stator in sequence, completing the overall assembly of the dry-type submersible motor, shortening auxiliary time and improving work efficiency. A rubber plate 7 is attached to the working surface of the movable V-shaped iron 2. Its functions are twofold: first, to ensure the dry-type submersible motor stator is placed on the movable V-shaped iron 2, preventing it from bumping; and second, to increase friction to ensure the dry-type submersible motor stator does not rotate when tightening the bolts 3.
