Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep well pump technology, specifically to a guide vane for a deep well pump. Background Technology
[0002] The working principle of a deep well pump is based on centrifugal force. When the motor starts, it drives the impeller to rotate at high speed through the drive shaft. The liquid enters the pump body axially under the action of the impeller and is thrown out under the action of centrifugal force. The liquid gradually slows down in the diffuser chamber of the pump casing, the pressure gradually increases, and then it is discharged from the pump outlet.
[0003] The prior art discloses a guide vane for a deep well pump, with publication number CN220452297U, specifically relating to the field of deep well pump technology. This utility model includes a guide vane body, with a cylinder fixedly connected to one side of the guide vane body. An adjustable support device is provided on the inner wall of the cylinder. The adjustable support device includes a threaded plate, the outer surface of which is inserted into the inner wall of the cylinder. Several support blocks are evenly arranged on one side of the threaded plate, each support block having a right-angled trapezoidal cross-section in the vertical direction. The threaded plate and the inner wall of the guide vane body are equipped with a disassembly device. This utility model, by providing a threaded plate, allows the threaded plate to slide on the inner wall of the cylinder, thereby moving the support blocks inside the cylinder. Simultaneously, the threaded pin and threaded block can limit the position of the threaded plate, facilitating adjustment of the support block position according to the impeller model. This allows for the normal installation of various impeller models, helping to maintain a high flow rate in the deep well pump.
[0004] The aforementioned threaded hole plate is balanced by threaded tubes and threaded pins. However, the threaded pins have threaded grooves on their surfaces. When the threaded hole plate moves, it is prone to blockage, making the disassembly or replacement of the threaded hole plate difficult and requiring a lot of time for maintenance.

[0028] The adjusting assembly 1 includes a connecting circular plate 11, an adjusting threaded rod 12, a moving assembly 13, and an adjusting threaded sleeve 14. The moving assembly 13 is installed on the bottom surface of the connecting circular plate 11. The adjusting threaded sleeve 14 is movably connected to the bottom surface of the connecting circular plate 11. The connecting circular plate 11 is threadedly connected to the surface of the adjusting threaded rod 12. The adjusting threaded sleeve 14 is threadedly connected to the surface of the adjusting threaded rod 12. The adjusting threaded sleeve 14 slides on the surface of the adjusting threaded rod 12. The adjusting threaded sleeve 14 can push the connecting circular plate 11 to move upward, thereby adjusting the position of the connecting circular plate 11. The adjusting threaded sleeve 14 is threadedly connected to the threaded end surface of the adjusting threaded rod 12. The connecting sleeve 4 is installed on the top of the adjusting threaded rod 12.
[0029] The movable component 13 includes a metal block 131, a threaded rod 132, a metal housing 133, a limiting block 134, a moving roller 135, a fixed threaded rod 136, a connecting rod 137, and a connector 138. The threaded rod 132 is fixedly connected to the outward end of the metal block 131, and the connector 138 is inserted into the outward end of the metal block 131. The metal housing 133 can drive the connector 138 to be inserted into the outward end of the metal block 131, while the metal housing 133 slides on the surface of the threaded rod 132. The device can lock and fix the metal block 131 and the metal shell 133, facilitating the disassembly and replacement of the metal block 131. The threaded rod 132 is connected to the inward end of the metal shell 133, and the limiting block 134 is threaded to the outward end of the metal shell 133. The fixing threaded rod 136 is fixedly connected to the outward end of the metal shell 133, and the limiting block 134 is movably connected to the surface of the connecting rod 137. The connecting rod 137 is rotatably connected to the outward end of the metal shell 133, and the limiting block 134 is slidably connected to... The surface of the fixed threaded rod 136 is threaded with a nut, which rotates on the surface of the fixed threaded rod 136. The metal housing 133 and the limiting block 134 can limit the connecting rod 137, thereby facilitating the disassembly and replacement of the connecting rod 137 and the moving roller 135. The moving roller 135 is fixedly connected to the middle position of the connecting rod 137 and is rotatably connected to the inner wall surface of the guide vane body 2. The connecting circular plate 11 is slidably connected to the guide vane body 2.

The connector 138 is fixedly connected to the inner wall surface of the metal shell 133 and movably connected to the bottom surface of the connecting circular plate 11. The metal block 131 is fixedly connected to the bottom surface of the connecting circular plate 11. The connecting circular plate 11 and the metal block 131 can determine the position of the connector 138, thereby facilitating the disassembly and replacement of the moving roller 135.
[0030] When in use, rotating the adjusting threaded sleeve 14 causes the adjusting threaded sleeve 14 to rotate on the surface of the adjusting threaded rod 12.

[0031] When the connecting plate 11 moves upward, it can drive the metal block 131 to move downward. The metal block 131 drives the metal shell 133 to move downward through the threaded rod 132. The metal shell 133 and the limiting block 134 drive the connecting rod 137 to move upward. The connecting rod 137 drives the moving roller 135 to move downward on the inner wall surface of the guide vane body 2, making the movement of the connecting plate 11 smoother and faster.
[0032] The connecting circular plate 11 drives the metal block 131 to move downward, and the connecting circular plate 11 and the metal block 131 can detach from the guide vane body 2.
[0033] Turn the nut, and the nut rotates on the surface of the threaded rod 132, loosening the connection between the metal block 131 and the metal shell 133.
[0034] Rotate the nut, and the nut rotates on the surface of the fixed threaded rod 136, which loosens the connection between the limiting block 134 and the metal shell 133, and pulls the limiting block 134 to move upward. The limiting block 134 moves upward on the surface of the metal shell 133, so that the limiting block 134 can be separated from the metal shell 133 and the fixed threaded rod 136.
[0035] Pulling the movable roller 135 upwards causes the connecting rod 137 to move upwards, allowing the connecting rod 137 and the movable roller 135 to detach from the metal housing 133, making it easy to disassemble and replace the movable roller 135.
[0036] Pulling the metal casing 133 outwards causes the connector 138 to move outwards. The connector 138 slides on the outward end of the metal block 131, allowing the metal casing 133 to detach from the metal block 131, making it easy to disassemble and replace the metal casing 133.
