Column tube heat exchanger installation technical requirements and precautions
May 15, 2018

Firstly, it is necessary to accurately install the heat exchangers in place. The installation of such large-scale units requires lifting. In order to ensure the safety in the lifting process, the hoisting department should prepare all machine rigging and carefully follow the safety rules. Do a good job of inspection.


For large pipe heat exchangers, because of their large diameter and many heat transfer tubes, the lifting mass is very large. Therefore, the lifting and binding should be selected at the reinforcement support plate of the shell support, and the wood is used on both sides of the housing. Maintain the shell so that the shell is not damaged by the plastic deformation of the steel wire rope during lifting.


When installing heat exchangers, there are also certain requirements for the device size bias, which should meet the requirements of relevant specifications. There are also requirements for the tube heat exchanger support device, usually the side of the active support base should be embedded skateboard, both sides of the anchor bolts have horn. Before the equipment is leveled, the inclined horn can be welded firmly to the base plate of the heat exchange unit, but it must not be welded to the flat horn or skateboard above, and the horn must be lubricated and leveled to ensure the free movement of the movable support.


In addition, the tightening of the bolts in the heat exchanger of the tubular heat exchanger shall be stopped at most three times, and the end points of each drive shall be staggered by 120° with each other. When the tube heat exchanger is accurately installed in place, it requires a professional use of its operation method.


In the process of using the heat exchangers, it is necessary to pay attention to the need to pay attention to the demineralized water. For any kind of water quality control, this is very important. Under the premise of dealing with the demineralized water quality, we must first carefully check the water in the system. And soften the tank water quality problem, if determined to be eligible for injection treatment.


At the same time, the new system needs to be inspected. Since the new system cannot be used interchangeably with the heat exchanger, first the new system is run for a specified period of time, and after it has a mode of operation, it can heat the heat at this time. The device is incorporated into the system for use. The purpose of doing so is to avoid impurities in the pipe network damaging the heat exchanger device.


There is also the need to pay attention to the cleanliness of the pipe network in the pipe heat exchanger, both before and after the work is completed. The purpose of this is to avoid the phenomenon of blockage of the heat exchanger. Also pay attention to the timely cleaning of the decontamination device and the filter, so that the entire work can be completed successfully.
