Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a tubular heat exchanger. Background Art

[0002] Tubular heat exchanger, also known as shell and tube heat exchanger, is a partition-type heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. Shell and tube heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale, but has a low heat transfer coefficient and occupies a large area. It can be manufactured with a variety of structural materials and can be used under high temperature and high pressure. It is the most widely used type.

[0003] When transporting the tubular heat exchanger, confirm that the inlet and outlet flanges of the heat exchanger have been equipped with blind plates to prevent debris from entering the heat exchanger during transportation. Use appropriate transportation tools and equipment, such as forklifts, cranes, etc., to ensure the stability and safety of the heat exchanger during transportation. During transportation, collision and vibration should be avoided to avoid damage to the heat exchanger.

By providing a support frame A, a support frame B and an electric push rod, the electric push rod is used instead of the lifting mechanism to drive the support frame B to drive the tubular heat exchanger between the tops of the support frame A to lift to the installation position, so as to assist in the installation and fixation of the tubular heat exchanger, thereby greatly improving the installation convenience.

The tubular heat exchanger may fall during transportation, thereby reducing the stability of the tubular heat exchanger during transportation. Therefore, we need a tubular heat exchanger.

The rotation of the first bevel gear 703 drives the second bevel gear 704 to rotate, changing the direction of rotation.
