Ventilation ducts are an important part of the smoke removal system and ensure the object with fresh air. It is on these channels that the air masses are moved. Such channels are made of corrugated pipes or can be made of soft pipes.
In any case, during operation, ventilation ducts are clogged with various extraneous elements. Dust and fat pollution accumulate in them. They significantly reduce the capacity of the channel, and its operation becomes less effective. In order for the system as a whole and ventilation ducts in particular in normal condition, it is necessary to periodically conduct their maintenance.
Timely maintenance of these channels meets the requirements of fire safety. Such work is the key to the safe operation of the entire object, allow when smoking and fires to prevent human casualties or any health threats. The main works that are performed during the maintenance of ventilation ducts should be considered in more detail:
- During the performance of work, the general condition of the air pipelines is necessarily evaluated. It is necessary to find out information about the presence of mechanical damage, deformations, as well as the causes that prevent the normal passage of the masses of air. At the same time, all the elements of the system are examined without exception;
- Air filters are checked. The presence of an efficient filtration system is the key to the work of the entire system. Therefore, when installing ventilation, filters are necessarily installed to detain dust and other contaminants. Depending on the state of these filters, they are replaced with new or cleaning;
- performed conducting electrophysical measurements . For example, the frequency of air exchange, the efficiency of the system and its compliance with the initial technical characteristics are evaluated and measured.
The data obtained according to the results of measurements and examinations should be drawn up with design indicators. If the system works poorly in any parameters, the company's specialists are adjusting the elements of the system. For example, valves, fans and so on. If the violations are more pronounced, then a list of defects is compiled and the ventilation system is repaired.
