[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Currently, it is usually necessary to install a retaining ring on the pump. The retaining ring is opened with retaining ring pliers and then clamped into the groove on the rotating shaft to ensure that the retaining ring is installed in place. At the same time, a press or hydraulic tool is also needed to press the water-throwing ring into the middle of the bracket return hole along the axis of the rotating shaft to ensure that the water-throwing ring and the rotating shaft are interference fit.

[0004] However, the installation space for the retaining ring and the water-spinning ring is small, making it inconvenient to assemble using the aforementioned tools. Furthermore, it is easy for the retaining ring and the water-spinning ring to be improperly assembled, which can lead to machine seal failure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a pump assembly tool, which aims to solve the problem that the installation space for the retaining ring and the water-slinging ring is small, making it inconvenient to assemble with the above tools, and easily leading to improper assembly of the retaining ring and the water-slinging ring, which in turn leads to the failure of the machine seal.

[0029] Please see Figures 1-6 The diagram shows a schematic of a pump assembly tool according to an embodiment of the present invention. The assembly tool operates on the pump's rotating shaft 300, which has a water outlet support 400. The assembly tool includes a first assembly component 100 sleeved on the rotating shaft 300 and a second assembly component 200 passing through the water outlet support 400.

[0030] To facilitate the installation of the retaining ring 500 and ensure the mechanical seal rotating ring 700 is properly installed, the first assembly assembly 100 is sleeved on the rotating shaft 300, with the retaining ring 500 located at one end of the first assembly assembly 100. The first assembly assembly 100 includes a sleeve 110 sleeved on the rotating shaft 300 and an assembly tube 120 sleeved on the sleeve 110. One end of the sleeve 110 abuts against the retaining ring 500 to partially cover the rotating shaft 300, preventing irreversible damage to the mechanical seal rotating ring 700 caused by burrs on the rotating shaft 300 during installation.

[0031] In this embodiment, the sleeve 100 is designed with a racetrack-shaped limiting liner. When the sleeve 110 is fitted onto the rotating shaft 300, the racetrack-shaped limiting liner can be used to check whether the size of the currently fitted rotating shaft 300 meets the requirements. At the same time, the bottom of the sleeve 100 can also protect the mechanical seal moving ring groove 127 and prevent the retaining ring groove on the rotating shaft from cutting the mechanical seal moving ring rubber.

[0032] Furthermore, the assembly tube 120 includes a tube body 121, press-fit handles 122 respectively disposed at both ends of the tube body 121, and a first assembly portion 123, wherein the first assembly portion 123 is provided with a plurality of receiving grooves. The tube body 121 is sleeved on the outside of the sleeve 110, and the press-fit handles 122 are disposed at the end of the tube body 121 away from the second assembly component 200, so as to apply force to the tube body 121 during the installation of the retaining ring 500.

[0033] Furthermore, to facilitate the installation of the retaining ring 500, a retaining groove 124, a retaining ring 500 placement groove 125, and a mechanical seal moving ring groove 127 are sequentially provided in the first assembly part 123 towards the second assembly component 200, with the diameters of the retaining groove 124, retaining ring 500 placement groove 125, and mechanical seal moving ring groove 127 increasing sequentially. The retaining ring 500 placement groove 125 is also provided with several locking interfaces 126, which are used to engage the pins of the retaining ring 500.

[0034] It is worth noting that the retaining ring 500 provided in this embodiment is a cross-shaped retaining ring 500. This cross-shaped retaining ring 500 has three pins around its perimeter for engaging with the retaining interface 126 on the retaining ring 500 placement groove 125, thereby completing the installation using the assembly tube 120. When the assembly tube 120 moves axially along the rotating shaft 300, the retaining ring 500 placement groove 125 drives the retaining ring 500 to move, and the mechanical seal moving ring groove 127 drives the mechanical seal moving ring 700 to move until the abutment groove 124 abuts against the step of the rotating shaft 300. At this point, the retaining ring 500 engages with the retaining ring 500 installation groove on the rotating shaft 300, and the retaining ring 500 restricts the mechanical seal moving ring 700, preventing it from moving axially along the rotating shaft 300, thereby achieving a sealing effect.

[0035] According to one aspect of the above technical solution, in order to install the water-spinning ring 600, the second assembly component 200 includes a handle portion 210, a second assembly portion 220 located at one end of the handle portion 210, and the water-spinning ring 600 disposed within the second assembly portion 220. The second assembly portion 220 has a circular groove 221 and a U-shaped plate 222 concentrically arranged with the circular groove 221, and the water-spinning ring 600 is placed on the U-shaped plate 222. When the second assembly portion 220 drives the water-spinning ring 600 into the water outlet bracket 400 and reaches a preset position, the rotating shaft 300 passes through the water-spinning ring 600 and the second assembly portion 220. By moving the handle portion 210, the second assembly portion 220 is moved, allowing the water-spinning ring 600 to be assembled into the center of the bracket's return hole, and to be interference-fitted with the rotating shaft 300. After assembly, the second assembly component 200 can be directly removed.

[0036] In summary, the pump assembly tool proposed in this utility model includes a sleeve fitted over the rotating shaft to prevent burrs on the shaft from causing irreversible damage to the mechanical seal's moving ring. An assembly tube is also fitted over the sleeve. By pressing the mounting handle along the axial direction of the assembly tube, a retaining ring is engaged in the retaining ring mounting groove on the rotating shaft, thus restricting the movement of the mechanical seal's moving ring and achieving a sealing effect. Simultaneously, a water-throwing ring is placed inside the second assembly component, which is then inserted into the outlet support, allowing the rotating shaft to pass directly through the water-throwing ring and the second assembly component. Moving the handle moves the second assembly component, assembling the water-throwing ring into the center of the support's return hole, where it is interference-fitted with the rotating shaft. After assembly, the second assembly component can be directly removed. This utility model reduces assembly difficulty and ensures proper assembly and sealing by utilizing the first and second assembly components to install the retaining ring and water-throwing ring respectively.
