Figures 1-2As shown, the device includes an axial limiting component, a pull frame 5, multiple pull rods 6, and a driving component. The axial limiting component includes a first pull plate 8, a second pull plate, and a locking component. The first and second pull plates are used to clamp the impeller from the back of the impeller, and the first and second pull plates can move closer or further apart from each other, and are held in their moved positions by the locking component. A clamping gap is formed between the first and second pull plates to allow the impeller pump shaft to pass through. The pull frame 5 is provided with a driving station. One end of each pull rod 6 is detachably fixed to the pull frame 5, and the other end is used to pass through the clamping gap and abut against the side of the axial limiting component away from the impeller. Each pull rod 6 is located on both sides of the driving station. The driving component is mounted on... Mounted at the drive station, the drive end of the drive component is used to abut against the impeller pump shaft to push the impeller pump shaft out of the impeller as the drive end of the drive component moves away from the pull frame 5. The axial limiting component can flexibly adjust and stabilize the positions of the first pull plate 8 and the second pull plate, which can not only adapt to impellers of different sizes, making the clamping more versatile, but also ensure the relative stability of the impeller during disassembly. The pull rod 6 connects the axial limiting component and the pull frame 5, playing a pulling and positioning role to ensure the stability of the entire device structure. The drive component provides a stable and reliable driving force for the impeller to be pushed out of the pump shaft by abutting against the impeller pump shaft. This structural design can realize impeller disassembly more efficiently and stably.

[0023] In a preferred embodiment, the driving component is an ejector screw 1, and the driving station is provided with a threaded hole 2. The ejector screw 1 is threadedly connected to the threaded hole 2. The threaded connection between the ejector screw 1 and the threaded hole 2 is simple to operate. By rotating the ejector screw 1, the distance between its driving end and the pull frame 5 can be smoothly changed, thereby achieving slow and uniform ejection of the impeller pump shaft, improving the accuracy and controllability of the operation, and effectively reducing the risk of damage to the impeller and pump shaft.

[0024] In a preferred embodiment, a hexagonal nut is fixedly connected to one end of the ejector screw 1. The end of the ejector screw 1 away from the hexagonal nut is used to abut against the impeller pump shaft. The hexagonal nut allows users to easily rotate the ejector screw 1 using common tools such as wrenches, reducing the difficulty of operation and improving the convenience of operation. It provides a clear and stable contact point for the ejector screw 1 to abut against the impeller pump shaft, ensuring the effective transmission of force during the ejection process and making the ejection action more reliable.

[0025] In a preferred embodiment, both the first pull plate 8 and the second pull plate are rectangular plates. The first pull plate 8 has a first iron pipe welded to both ends, and the second pull plate has a second iron pipe welded to both ends. The locking components include a fastening bolt 7 and a fastening nut 9. The fastening bolt 7 is used to pass through the first and second iron pipes and be threaded to the fastening nut 9. Rotating the fastening nut 9 can adjust the clamping gap. The rectangular plate has a simple structure and is easy to manufacture. The welded first and second iron pipes provide a connection point for the fastening bolt 7, making the operation of adjusting the clamping gap by rotating the fastening nut 9 more flexible and precise.

[0026] In a preferred embodiment, the device further includes multiple first locking nuts 3. The pull bracket 5 is provided with multiple elongated holes 4 symmetrically arranged about the threaded holes 2. The pull rod 6 is a tensioning screw. The end of the tensioning screw away from the axial limiting member passes through the elongated hole 4 and is threadedly connected to the first locking nuts 3 to restrict the pull bracket 5 from moving away from the axial limiting member. The combination of multiple first locking nuts 3, elongated holes 4, and tensioning screws not only allows for flexible adjustment of the position of the pull rod 6 to adapt to different scenarios, but also allows the pull bracket 5 to be firmly fixed to the pull rod 6 by tightening the first locking nuts 3, preventing displacement of the pull bracket 5 during the operation of the drive component, ensuring the structural stability of the entire disassembly tool, thereby ensuring the smooth progress of the impeller disassembly operation and avoiding problems such as disassembly failure or component damage caused by loosening of the pull bracket 5.

[0027] In a preferred embodiment, a plurality of second locking nuts are also included. The end of the tensioning screw away from the pull rod 5 is used to pass through the clamping gap and be threadedly connected to the second locking nuts to restrict the axial limiting member from moving away from the pull rod 5.

[0028] In a preferred embodiment, the device further includes multiple first washers and multiple second washers. Both the first and second washers are sleeved on the outside of the tensioning screw. The first washers are positioned between the first locking nut 3 and the tie rod 5, and the second washers are positioned between the second locking nut and the axial limiting member. The first and second washers can increase the contact area of ​​the connection, disperse the concentrated stress generated when the nut is tightened, and prevent damage to the tie rod 5 and the axial limiting member. At the same time, they can also play a certain buffering role, reduce the vibration impact of the device during operation, and improve the service life and working stability of the entire device.

[0029] The following is the usage method of this patented single-suction water pump impeller disassembly tool:

[0030] 1. Preparation

[0031] Check the integrity of the tool: Carefully inspect each part of the tool to ensure that the axial limiting parts (including the first pull plate 8, the second pull plate and the locking parts), the pull bracket 5, the multiple pull rods 6, the drive part (ejector screw 1) and other auxiliary parts (such as the first locking nut 3, the second locking nut, the first washer and the second washer) are complete and undamaged.

[0032] Select appropriate components: Based on the size of the single-suction water pump impeller to be disassembled, estimate the appropriate clamping clearance and prepare components such as the first pull plate 8 and the second pull plate of the corresponding size.

[0033] 2. Install axial limiting components

[0034] Place the pull plate: clamp the impeller from the back of the impeller with the first pull plate 8 and the second pull plate, so that the impeller pump shaft passes through the clamping gap formed between the first pull plate 8 and the second pull plate.

[0035] Adjust and lock the gap: Operate the locking component, that is, rotate the fastening nut 9 so that the fastening bolt 7 passes through the first iron pipe and the second iron pipe and is connected to the fastening nut 9 by thread, thereby adjusting the clamping gap between the first pull plate 8 and the second pull plate to ensure that it firmly locks the impeller pump shaft and does not cause excessive compression to the impeller pump shaft.

[0036] 3. Install tie rod 6

[0037] Connecting the pull bracket 5 to the axial limiting member: Pass the end of the pull rod 6 (tensioning screw) away from the axial limiting member through the elongated holes 4 symmetrically arranged with respect to the threaded holes 2 on the pull bracket 5, and then thread it to the first locking nut 3. During this process, in order to limit the movement of the pull bracket 5 away from the axial limiting member, the first locking nut 3 can be tightened appropriately. At the same time, pass the end of the tensioning screw away from the pull bracket 5 through the clamping gap and thread it to the second locking nut, thereby limiting the movement of the axial limiting member away from the pull bracket 5, and install the second washer, placing it between the second locking nut and the axial limiting member. In addition, install the first washer between the first locking nut 3 at the end of the pull bracket 5 and the pull bracket 5.

[0038] 4. Install the driver.

[0039] Connect the end of the drive component (ejector screw 1) with the hexagonal nut to the threaded hole 2 of the drive station with a thread to ensure that the ejector screw 1 can rotate smoothly in the threaded hole 2 and that the end of the ejector screw 1 away from the hexagonal nut can accurately abut against the impeller pump shaft.

[0040] 5. Impeller disassembly operation

[0041] Using a wrench or similar tool, turn the hexagonal nut on the ejector screw 1, causing the drive end of the ejector screw 1 to gradually move away from the pull bracket 5 under the action of the threads. During this process, the ejector screw 1 abuts against the impeller pump shaft, slowly and smoothly pushing the impeller pump shaft out of the impeller, completing the disassembly of the single-suction water pump impeller.

[0042] 6. Tool storage

[0043] After disassembly, loosen the second locking nut and the first locking nut 3 in sequence, and remove the pull rod 6 from the pull bracket 5 and the axial limiting member. Next, rotate the ejector screw 1 to unscrew it from the threaded hole 2. Then loosen the locking nut 9 and remove the first pull plate 8 and the second pull plate. Finally, organize and store all parts of the tool for future use.

[0044] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
