The sealing tile is used as an important sealing part of the oil receiver of the unit, and the oil leakage is increased due to poor dismounting and mounting process. The traditional disassembly and assembly process has a lot of inconvenience and potential safety hazards, and needs to be improved to simplify the process, ensure safety, reduce labor input and improve efficiency and process guarantee. The traditional disassembling and assembling process mainly has the following defects:

1. the personnel are dense and the environment is narrow.

2. The potential safety hazard is avoided: in the traditional process, the hammer is used for knocking the copper rod to transfer force to the sealing tile for installation, so that potential safety hazards of copper rod slippage and hammer deflection exist; according to the traditional process, the hammer strikes the puller hook foot and is transmitted to the sealing tile for disassembly, the contact area between the puller hook foot and the first-order boss of the sealing tile and the contact area between the hammer and the puller are small, and potential safety hazards of puller slipping and hammer deflection exist in the disassembly process.

3. The defect of easy damage to the workpiece is as follows: during installation, the sealing tile is damaged due to overlarge knocking force and deviation of the knocking position, and the sealing tile needs to be machined again once being seriously damaged; when the sealing device is detached, the contact area between the puller hook foot and the sealing tile is small, if the knocking force is too large, the sealing tile is damaged, and other parts can be damaged due to knocking position deviation.

4. The big shortcoming of dismouting degree of difficulty: the dismouting process can not seek soon, causes deviation about too soon easily, beats the dynamics inequality and can appear holding back strength card and die, and the installation need measure from time to time.

5. The long time of the disassembling and assembling work.

In order to solve the problems, the disassembly and assembly structure of the sealing bush of the oil receiver of the improved tubular unit is provided again.
