Tube bundle extractor is a mechanical device used for the tube bundle extraction operations of shell-and-tube heat exchangers. Its components include lifting cylinders, side pulling cylinders, and clamping cylinders. These cylinders play crucial roles in the operation process of the tube bundle extractor. Here is a detailed analysis:

Lifting Cylinder

2. • Function: The lifting cylinder primarily provides vertical support during the tube bundle extraction process, ensuring that the tube bundle can be smoothly removed or inserted. During the operation, when the tube bundle needs to be pulled out from the shell, the lifting cylinder extends to support one end of the tube bundle, keeping it balanced.
   • Characteristics: The lifting cylinder usually has high load-bearing capacity and stability to ensure that the tube bundle does not tilt or wobble during the extraction process. Additionally, its extension speed must be appropriately controlled to meet the requirements of different working conditions.
3.  

Side Pulling Cylinder

4. • Function: The main role of the side pulling cylinder is to provide horizontal pulling or pushing force during the tube bundle extraction process. When pulling out the tube bundle, the side pulling cylinder extends and pulls the other end of the tube bundle, working together with the lifting cylinder to keep the tube bundle stable and smoothly extracted. When inserting the tube bundle, the side pulling cylinder provides reverse thrust to help the tube bundle enter the shell smoothly.
   • Characteristics: The side pulling cylinder has a large range of pulling and pushing forces to meet the extraction needs of tube bundles with different diameters and weights. Additionally, its operation requires precise control to ensure that the tube bundle is not damaged during the extraction process.
5.  

Clamping Cylinder

6. • Function: The clamping cylinder plays a fixing and clamping role during the tube bundle extraction process. Before pulling out the tube bundle, the clamping cylinder firmly clamps one end of the tube bundle onto the extractor to prevent sliding or falling off during the extraction process. When inserting the tube bundle, the clamping cylinder is responsible for accurately positioning the tube bundle inside the shell and keeping it stable.
   • Characteristics: The clamping cylinder typically has strong clamping force and stable clamping effects to ensure the safety and reliability of the tube bundle during the extraction process. Additionally, its structure needs to be compact and easy to operate and maintain.

How do the lifting cylinder and side pulling cylinder work together during tube bundle extraction? During tube bundle extraction, the lifting cylinder and side pulling cylinder work together in the following ways:

When needing to extract the tube bundle, the lifting cylinder first extends to lift the tube bundle to a certain height, providing initial support and stability. Then, the side pulling cylinder extends and applies pulling force, working together with the lifting cylinder to smoothly pull the tube bundle out of the shell. In this process, both components cooperate to overcome the gravity and resistance of the tube bundle, ensuring smooth extraction.

When needing to insert the tube bundle, the actions of the lifting cylinder and side pulling cylinder are reversed. The side pulling cylinder first pulls the tube bundle to the correct position, and then the lifting cylinder adjusts the position and posture of the tube bundle to accurately insert it into the shell, with the clamping cylinder finally securing it. Throughout the process, the lifting cylinder and side pulling cylinder work closely together to achieve the tube bundle extraction operation.

The clamping cylinder plays a key role in the tube bundle extraction process. It is mainly responsible for firmly holding and fixing the tube bundle.

Before extracting the tube bundle, the clamping cylinder tightly clamps one end of the tube bundle, ensuring that the tube bundle does not wobble or slip during the extraction process, guaranteeing the safety and stability of the operation.

When installing the tube bundle, the clamping cylinder also plays an important role by accurately positioning the tube bundle at the right spot inside the shell and keeping it stable to facilitate the successful completion of the installation work.

In summary, it can be said that the lifting cylinder, side pulling cylinder, and clamping cylinder each undertake important roles in the tube bundle extractor. They collaborate to ensure the smooth progress and efficient completion of the tube bundle extraction process.
