Description

Technical Field

[0001] This utility model relates to a double-headed ceramic pump impeller disassembly and assembly tool, belonging to the technical field of ceramic pump processing equipment. Background Technology

[0002] A ceramic pump is a type of pump primarily made of ceramic materials, possessing excellent corrosion resistance, wear resistance, and resistance to high temperatures and pressures. Its structure mainly includes the pump body, impeller, shaft, motor, and mechanical seal. A double-headed ceramic pump has two pump heads, allowing it to simultaneously pump materials to two devices. After prolonged use, severe corrosion can occur between the shaft and impeller of a double-headed ceramic pump, causing them to stick together. This makes disassembly of the shaft and impeller difficult. Some existing tools for disassembling double-headed ceramic pumps require manual hammering to separate the shaft and impeller, a difficult and potentially dangerous operation. Utility Model Content

[0022] Example 1: As shown in the attached document Figures 1-6 As shown, a double-headed ceramic pump impeller disassembly and assembly tool includes a workbench 1 and a support frame 3. Support legs 2 are fixedly connected to the four lower corners of the workbench 1. The support frame 3 is fixedly connected to the lower side of the workbench 1. A support plate 4 is fixedly connected to the upper side of the support frame 3. Two symmetrically distributed first hydraulic rods 5 are fixedly connected to the upper side of the support plate 4. Clamping blocks 6 are fixedly connected to the opposing sides of the two first hydraulic rods 5. A pair of first sliding blocks 7 are fixedly connected to the upper side of each clamping block 6. A pair of second sliding blocks 8 are fixedly connected to the lower side of each clamping block 6. The upper side of the support frame 3 is fixedly connected to... Two second hydraulic rods 9 are fixedly connected to the upper side of each second hydraulic rod 9. A bearing plate 11 is fixedly connected between the two transmission blocks 10. Two guide shafts 12 with symmetrical front and rear distribution are fixedly connected to the lower side of the bearing plate 11. Two third hydraulic rods 13 with symmetrical left and right sides are fixedly connected to the upper side of the worktable 1. A support plate 14 is fixedly connected to the back side of each of the two third hydraulic rods 13. The lower side of the support plate 14 is fixedly connected to the worktable 1. A limit seat 15 is fixedly connected to the upper side of each third hydraulic rod 13. A limit plate 16 is slidably connected between the two limit seats 15.

[0023] The worktable 1 has two rectangular mounting slots symmetrically distributed from left to right. The worktable 1 is fixedly connected to the second hydraulic rod 9 through the mounting slots. The worktable 1 also has two U-shaped guide slots symmetrically distributed from front to back. The worktable 1 is slidably connected to the guide shaft 12 through the guide slots, and the bearing plate 11 is moved stably through the guide shaft 12. The lower side of the worktable 1 has two pairs of first sliding slots. The worktable 1 is slidably connected to the first sliding block 7 through the first sliding slots. The upper side of the support plate 4 has two pairs of second sliding slots. The support plate 4 is slidably connected to the second sliding block 8 through the second sliding slots. The clamping block 6 can be moved stably through the first sliding block 7 and the second sliding block 8. The middle position of both the worktable 1 and the support plate 4 has a cylindrical through slot. The opposing sides of the two clamping blocks 6 are curved surfaces. The first sliding block 7 and the second sliding block 8 are both... The components are symmetrically distributed vertically. The first sliding block 7 and the second sliding block 8 are both T-shaped blocks, which can clamp the rotating shaft through the clamping block 6. The opposing sides of the two second hydraulic rods 9 are fixedly connected to the support plate 4. The middle position of the bearing plate 11 is provided with a circular through groove, and the upper side of the bearing plate 11 is provided with a circular limiting protrusion. The bearing plate 11 supports the impeller and prevents the impeller from falling. The guide shafts 12 are all U-shaped shafts. The back side of the guide shaft 12 is aligned with the outer curved surface of the bearing plate 11. The opposing sides of the two third hydraulic rods 13 are in contact with the transmission block 10. The transmission block 10 drives the bearing plate 11 to move upward. The support plates 14 are all inclined. The limiting seats 15 are all provided with limiting grooves. The left and right sides of the limiting plate 16 are provided with limiting blocks. The clamping of the clamping block 6 and the pressing of the limiting plate 16 keep the rotating shaft vertical.

[0024] The workflow of the double-headed ceramic pump impeller disassembly and assembly tool described in Example 1 is as follows:

[0025] Before use, the workbench 1 is fixed in a suitable position by the support leg 2 and the power is turned on. The device is equipped with an external controller, which is electrically connected to the first hydraulic rod 5, the second hydraulic rod 9 and the third hydraulic rod 13 respectively. The operating status of the first hydraulic rod 5, the second hydraulic rod 9 and the third hydraulic rod 13 can be adjusted by manually operating the external controller. All of the above are existing technologies.

[0026] When using this device, first remove the limiting plate 16, place the impeller fitted on the rotating shaft inside the limiting protrusion of the bearing plate 11, so that the rotating shaft passes through the through groove of the bearing plate 11, the through groove of the worktable 1, and the through groove of the support plate 4 in sequence. Then, adjust the second hydraulic rod 9 fixed by the support frame 3 through the external controller so that the two second hydraulic rods 9 extend upwards synchronously. The transmission block 10 drives the bearing plate 11 to move upwards, and the guide shaft 12 makes the bearing plate 11 move stably. This adjusts the height of the bearing plate 11 so that the lower side of the impeller contacts the bearing plate 11 and the bottom end of the rotating shaft contacts the support frame 3. Then, adjust the first hydraulic rod 5 fixed by the support plate 4 through the external controller so that the two... The first hydraulic rod 5 extends synchronously, allowing the two clamping blocks 6 to approach each other. The first sliding block 7 and the second sliding block 8 enable the clamping blocks 6 to move stably. The clamping blocks 6 clamp the rotating shaft, ensuring its verticality. Then, the limiting plate 16 is installed between the two limiting seats 15. The third hydraulic rod 13, supported by the support plate 14, is adjusted by the external controller, causing the two third hydraulic rods 13 to retract downwards synchronously. The limiting seat 15 drives the limiting plate 16 to move downwards, making the limiting plate 16 contact the upper end of the rotating shaft. At this time, the rotating shaft cannot move up or down. Subsequently, the two second hydraulic rods 9 extend synchronously upwards, pushing the impeller upwards through the bearing plate 11, thus removing the impeller from the rotating shaft.

[0027] If the impeller needs to be reinstalled, the second hydraulic rod 9 can be fully retracted to place the impeller on the bearing plate 11. Then, the shaft is placed above the impeller mounting hole, so that the third hydraulic rod 13 extends upward and the limiting plate 16 contacts the upper end of the shaft. Then, the third hydraulic rod 13 is retracted to install the impeller onto the shaft.

[0028] This utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
