[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three types according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. In addition to being classified by working principle, they can also be divided into linear pumps and traditional pumps according to their shaftless structure. Traditional pumps are all equipped with a pump shaft inside. To protect the pump shaft, a shaft sleeve is usually set on the pump shaft.

Under the action of the clamping block 10 and the clamping groove 12, it is convenient to set the shaft sleeve 3 on the pump body 1, thereby completing the installation of the shaft sleeve 3. A second spring 11 is also arranged on the inner wall of the mounting block 9, and the other end of the second spring 11 is connected to the clamping block 10. At this time, under the action of the clamping block 10 and the clamping groove 12, the installation and fixing quality of the shaft sleeve 3 and the pump body 1 is guaranteed, thereby ensuring the use efficiency of the shaft sleeve 3.

[0024] A plurality of sliders 4 are evenly arranged inside the mounting frame 2, a first plug rod 5 is arranged on the side wall of the slider 4, and a plug hole used in conjunction with the first plug rod 5 is arranged on the card block 10. Under the action of the first plug rod 5 and the plug hole, the connection quality of the card block 10 and the card slot 12 is guaranteed, thereby further improving the installation quality of the shaft sleeve 3. A plurality of support rods 6 are also slidably arranged on the mounting frame 2, and the left end of the support rod 6 is connected to the slider 4. The support rod 6 can be used to drive the slider 4 to move. A first spring 7 is also sleeved on the outer side of the support rod 6, and one end of the first spring 7 is connected to the sliding block 10. The first spring 7 is connected to the block 4, and the other end of the first spring 7 is connected to the mounting bracket 2. At this time, under the action of the first spring 7, it is ensured that the first plug rod 5 can be better plugged into the block 10, thereby ensuring the connection quality of the block 10 and the slot 12. A handle 8 is provided at the right end of the support rod 6, and the support rod 6 can be used to drive the slider 4 to move through the handle 8, so that the first plug rod 5 releases the restriction on the block 10, thereby facilitating the staff to remove the shaft sleeve 3 from the pump body 1, and then to inspect the shaft sleeve 3, thereby ensuring the use efficiency of the shaft sleeve 3.

[0025] The shaft sleeve 3 is also provided with an injection port 13, and a sealing cover 15 is provided on the injection port 13. Lubricating oil can be added to the inside of the shaft sleeve 3 under the action of the injection port 13, thereby ensuring the use efficiency of the shaft sleeve 3. At the same time, under the action of the sealing cover 15, the injection port 13 can be sealed, thereby reducing the occurrence of lubricating oil leakage, ensuring the lubricating effect of the lubricating oil on the inside of the shaft sleeve 3, thereby improving the wear resistance of the shaft sleeve 3.

[0026] A support plate 14 is further provided on the side wall of the sleeve 3 at the left and right sides of the liquid injection port 13, a cavity is further provided inside the sealing cover 15, a slide rod 16 is provided in the cavity, left and right slide plates 17 are slidably provided on the slide rod 16, a second plug rod 18 is provided on the side wall of the slide plate 17, and a socket for use with the second plug rod 18 is provided on the support plate 14.

One end of the third spring 19 is connected to the left skateboard 17, and the other end of the third spring 19 is connected to the right skateboard 17. At this time, under the action of the third spring 19, the connection quality between the second plug rod 18 and the support plate 14 is improved, thereby ensuring the sealing performance of the sealing cover 15. A paddle 20 is also provided at the bottom of the skateboard 17. The paddle 20 can be used to drive the skateboard 17 and the second plug rod 18 to move, thereby facilitating the removal of the sealing cover 15, and then facilitating the staff to add or discharge lubricating oil through the injection port 13.

[0027] In actual use, when the sleeve 3 needs to be installed, the staff pulls the handle 8 outward so that the support rod 6 drives the slider 4 to move, thereby allowing the first plug rod 5 to release the restriction on the block 10 and pull the block 10 outward, and then the sleeve 3 is sleeved on the power output shaft of the pump body 1, and its internal components are keyed to the power output shaft to ensure their coaxial rotation. When the block 10 is aligned with the slot 12, the block 10 is released. Under the action of the second spring 11, the block 10 is inserted into the slot 12. At the same time, the handle 8 is released so that the first plug rod 5 is inserted into the block 10, thereby completing the installation of the sleeve 3. At the same time, the staff can use the injection port 13 to add lubricating oil to the inside of the sleeve 3, thereby ensuring the use efficiency of the sleeve 3, and at the same time, the wear resistance of the sleeve 3 is improved to a certain extent, thereby ensuring the use efficiency of the sleeve 3.
