[0002] During the installation and maintenance of pumps, the correct installation of bearings and seals is crucial to ensure the efficient and stable operation of the pump. Traditional bearing and seal installation methods often rely on manual direct operation or the use of simple installation tools. This method is not only inefficient, but also difficult to ensure the flatness and concentricity of the bearing and seal installation, which can easily cause pump vibration, increased noise, and even damage to the bearings.

[0003] Especially when installing mechanical seals, higher installation accuracy is required. Since the mechanical seal needs to achieve precise sealing on the bearing, the installation position, flatness and concentricity of the bearing and the mechanical seal must be strictly controlled. Traditional installation methods are difficult to meet these requirements, especially when the bearing and the mechanical seal need to be accurately pushed and positioned during the installation process. It is even more difficult. Therefore, in response to the above technical problems, a sleeve structure that is convenient for pushing the bearing and the mechanical seal is proposed.
