What is the role of bearings for tunnel fans
The main function of the bearing is to support the rotation of the high pressure centrifugal fan. Reduce the coefficient of friction during rotation to ensure rotation accuracy and stability. It is understood that the tunnel fan rotates. The shaft can be fixed to rotate the shaft or to control the movement of the shaft. Radial bearings don't work. All can move in any direction. Just need to rotate.
Only open the installation when you are ready. The installation dust is not removed, which has a great impact on the duration. Life. Install bearings using clean gasoline or benzene. Blow the dust with compressed air. In addition, use kerosene and diesel oil as cleaning fluids, but if they are used alone, they will fall into very fine dust, which is difficult to clean. Lots of clean tools that can be assembled or disassembled. The tools must be used in accordance with the tunnel fan bearing instructions. How to disassemble the props? Use a special tool to remove it for a specific person, and please do not hit it with a hammer under any circumstances. Leading to accidents and failure of high pressure centrifugal fans.
For spherical roller bearings, in order to reduce the large gap between the two end faces, attention must be paid to the correct mounting position. Otherwise, the bearing will be worn out early during use, the turbine will be damaged, and the bearing will be affected. High pressure centrifugal fan life.
With the continuous development of science and technology, the demand for the use of tunnel fans is also increasing. Judging from the current development trend of foreign tunnel fan technology, it will develop in the direction of low-noise tunnel fans. Tunnel fan noise is one of the most important sources of noise pollution in industrial production.
The large-scale and high-speed tunnel fans make the noise problem very prominent. For low-frequency noise, the structural design of the tunnel fan should be improved to reduce the noise of the vehicle body. If the requirements cannot be met, measures such as installing mufflers and tunnel fan sound insulation rooms can be taken. To sum up, these technologies are not only the development trend of foreign tunnel fans in the future, but also technically the direction of domestic tunnel fans.
The selection of the tunnel fan should be carried out according to the actual situation of the plant. The type of tunnel fan should match the original window size as closely as possible. A certain distance should be kept between the tunnel fan and the wet curtain (try to install on both sides of the gable of the factory building) to achieve a good ventilation effect. The exhaust side of the tunnel fan should not be close to adjacent buildings as far as possible, so as not to affect adjacent residents. For example, if the air in the room contains environmental pollution, a water spray device can be installed at the tuyere to absorb and collect adjacent pollutants, so as not to pollute the environment and achieve the purpose of high efficiency and energy saving.
