Preliminary Discussion on the Preparation and Main Functions of Plate Heat Exchanger Core Pulling before Hoisting

Plate heat exchangers, a commonly used heat exchange equipment in our daily lives, have a strong heat exchange effect and good heat exchange efficiency. In fact, everyone knows that equipment has important components, and the core pulling of plate heat exchangers can be said to be such a component. Many people are not yet aware of its main function, Below, we will briefly understand the preparation work and main functions of the core pulling of the lower plate heat exchanger before lifting.

1. When lifting the equipment core from the core extractor, it is not allowed to directly bind the pipe bundle with steel wire ropes or other sharp slings. When the tube bundle is placed horizontally, it needs to be supported on the tube plate or support plate.

Ensure that the lifting equipment used is rated for the weight of the core and that all safety protocols are followed. Use soft slings or padded lifting straps to avoid damaging the pipe bundle. When placing the tube bundle horizontally, ensure that the support points are evenly distributed to prevent bending or deformation. Inspect the tube plate or support plate for any signs of wear or damage before use.

2. Before disassembly, timely measure and record the compression length of the plate bundle.

Detail: Use a calibrated measuring tool to accurately measure the compression length. Record the measurements in a logbook or digital record system for future reference. Double-check the measurements to ensure accuracy. Note the date, time, and personnel involved in the measurement process. This information is crucial for reassembly and ensuring the equipment operates correctly.

3. During the core pulling process of the plate heat exchanger, the disassembled plate heat exchanger parts should be marked and properly stored.

Detail: Use a systematic labeling system to mark each component, indicating its position and orientation. Use durable, non-corrosive markers or tags that can withstand the working environment. Store the components in a clean, dry area to prevent contamination or damage. Use protective covers or containers to keep the parts organized and easily accessible. Maintain a detailed inventory list of all disassembled components, including their condition and any observations made during disassembly.

4. During the core pulling inspection, the core pulling machine should have sufficient pulling force and propulsion force, and be able to automatically align. The gravity stability operation should be flexible and stable. The lifting and core pulling work of the equipment requires everyone to keep relevant records. We need to do some preparatory work before lifting and core pulling. No matter what operation we perform, we must maintain the equipment properly when placed horizontally.
