Heat Exchangers FHC060 Exporters

Maintenance of the axial flow fan of the heat exchanger: 1. Check the centering of the heat exchanger and the belt tension. 7. Eliminate defects such as gas channel leakage points. Clean the dirt, especially the dirt on the blades. Check and tighten the anchor bolts of each heat exchanger. 6

The heat exchange unit has a complex structure and many parts, so the precision of disassembly and assembly is very high. For example, if the thread is stuck in the middle of disassembly and assembly, it will cause serious consequences. Due to the complexity of the maintenance process and the relatively high technical difficulty, the maintenance plan should be carefully formulated before the maintenance.

Therefore, the heat exchange unit should be strictly aligned with precision during installation, and handled reasonably to avoid such failures..The maintenance procedures of the heat exchange unit are divided into disassembly, maintenance, and installation steps. The maintenance plan of the heat exchange unit should be correct, reasonable, specific and detailed, and discuss and study with the technicians to ensure the smooth progress of the maintenance work

After the tube bundle is in place, measure the axial and radial positions of the heat exchanger tube bundle and compare with those before disassembly to confirm whether the shell side gasket is installed correctly, and then carefully remove the gasket protection frame. The outer rear building or saddle bracket of the heat exchanger can be used Heat Exchangers FHC060 Exporters to axially lock the shell with steel wire rope and electric hoist core pulling machine. The installation method of the tube bundle is opposite to the core-pulling scheme.Before installing the heat exchanger tube bundle, check that the gasket on the sealing surface is installed properly.
