通風管道風機緊固件失效原因

建筑中的通風管道是調(diào)節(jié)室內(nèi)空氣和溫度的一個重要裝飾，與之配套的是風機，風機就相當于動力源把空氣輸入和排出。江蘇通風管道發(fā)現(xiàn)有時風機在長時間運轉(zhuǎn)的時候會出現(xiàn)緊固件松動的現(xiàn)象，那么這是怎么回事呢我們一起來看一下。

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.

一旦風機的緊固件失效，就會對風機的運行產(chǎn)生一定是我影響，嚴重的還會損壞風機。因此，當風機在運行時就應(yīng)該避免這種情況的發(fā)生。一般的，屋頂風機在常溫下運行時會有些溫度偏高的情況，不過都是在正常范圍之內(nèi)，這是由于機器本身的零件相互摩擦，產(chǎn)生熱量導致機身溫度偏高，但并不是所有溫度過高的情況都是正常的。

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.

實驗結(jié)果表明，導致屋頂風機緊固件失效的原因主要有以下幾點：1、運轉(zhuǎn)時，承受過大載荷量。就以軸流風機為例。由于它的運作時葉輪的輸出轉(zhuǎn)速快，因而，所要承受的載荷也就較大。一旦它的載荷超出的載荷范圍，其內(nèi)部個零件也需將承擔一些載荷量，這就會造成零件緊固件失效。2、驟時開啟反轉(zhuǎn)。如果在風機還未完全停止時，突然開啟反轉(zhuǎn)，就會使風機的各個部件在受慣性的作用下，分別向不同的方向運行，使其個部件的運行不同步，從而導致風機出現(xiàn)問題。

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.

在發(fā)現(xiàn)風機出現(xiàn)緊固件松動現(xiàn)象時應(yīng)該及時的進行處理，否則的話可能會導導致更大的問題發(fā)生。

In case of loose fasteners of the fan, it should be handled in time, otherwise it may lead to greater problems.
