What inspection work should be done before the use of fire fan advantages

Release Time：2021-07-20

Fire fan should first consider the characteristics of temperature and time, that is, 280 ℃/0.5h stipulated by the state, and then, under the general working temperature, it can ensure a reasonable amount of smoke exhaust system control.
In addition, it also stipulates that the fire-fighting fan can carry out regular tests, which can be found to be insufficient and improved. It can be used in various natural ventilation pipelines, which is conducive to installation and application. The characteristics of the fire-fighting fan are excellent in heat resistance, high efficiency, less floor space than centrifugal fans and high temperature characteristics.
The fire fan can operate continuously for more than one hour under the high temperature standard of 300 ℃, and will not be damaged for 20 hours under the temperature standard of 100 ℃. It has a wide application coverage and can be driven by speed regulation or multi-speed according to different regulations of high-grade industrial buildings. The fire fan is widely used in high-grade industrial buildings, electric ovens, underground parking lots, tunnel construction and other places. It is easy to install and can be installed immediately installed on walls, the installation can be vertical, translational or hoisting, which saves the floor space on a very large level.
In order to make the fire exhaust fan equipment can always be in a good running state, on the eve of its operation, the same need to start some inspection work.
One of the key inspection work of the fire exhaust fan is the vibration and noise level displayed by the fire exhaust fan equipment before it runs. Therefore, it is necessary to inspect the bearings of the fan coupling. The important inspection contents include: 1, axial oscillation, 2, vertical oscillation, 3, horizontal oscillation, 4, noise level, in addition, the bearings on the other side of the fan should also be checked in accordance with these contents. As long as abnormalities are found, they must be handled in time.
Perhaps, the bearing on the motor coupling side of the fire-fighting smoke exhaust fan equipment also needs to complete these inspections. In addition, we should also consider the temperature of the bearing. For the bearing on the coupling side of the fan, the temperature of the fire-fighting smoke exhaust fan is generally measured after 15 minutes of driving, and the temperature of the bearing on the other side of the fan should also be measured after 15 minutes of driving.
As for the inspection content of the lubricating oil system of the fire exhaust fan, it is also important to include the inspection of oil level, temperature and flow. In addition, it is important for us to inspect and predict the quality of the shaft seal through the temperature rise. It is also necessary to inspect the gas flow control mechanism, such as the relationship between voltage and exhaust pressure, and the control power supply of the control mechanism.
Therefore, before use, the inspection of the fire exhaust fan is necessary to prepare, so as to avoid the use of impact stability.
