The ventilation duct in the building is an important decoration to regulate the indoor air and temperature. It is matched with the fan, which is equivalent to the power source to input and discharge the air. It is found in Jiangsu ventilation duct that sometimes the fasteners of the fan will be loose when it runs for a long time. So what's going on? Let's have a look.
Once the fastener of the fan fails, it will have a certain impact on the operation of the fan, and seriously damage the fan. Therefore, this situation should be avoided when the fan is running. Generally, when the roof fan operates at normal temperature, there will be some cases of high temperature, but they are all within the normal range. This is due to the high temperature of the fuselage caused by the friction between the parts of the machine itself, but not all cases of high temperature are normal.
The experimental results show that the main reasons for the failure of fasteners of roof fan are as follows: 1. Bear excessive load during operation. Take the fan shaft as an example. Because the output speed of the impeller is fast during its operation, the load to be borne is large. Once its load exceeds the load range, its internal parts also need to bear some load, which will cause the failure of part fasteners. 2. Turn on the reverse when suddenly. If the fan is suddenly turned on and reversed before it has completely stopped, each part of the fan will run in different directions under the action of inertia, making the operation of each part asynchronous, resulting in problems of the fan.
In case of loose fasteners of the fan, it should be handled in time, otherwise it may lead to greater problems.
