通风管道风机紧固件失效原因

来源:http://cqlej.com 日期:2022-03-30 发布人:jntfgd

建筑中的通风管道是调节室内空气和温度的一个重要装饰,与之配套的是风机,风机就相当于动力源把空气输入和排出。江苏通风管道发现有时风机在长时间运转的时候会出现紧固件松动的现象,那么这是怎么回事呢我们一起来看一下。
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.
一旦风机的紧固件失效,就会对风机的运行产生一定是我影响,严重的还会损坏风机。因此,当风机在运行时就应该避免这种情况的发生。一般的,屋顶风机在常温下运行时会有些温度偏高的情况,不过都是在正常范围之内,这是由于机器本身的零件相互摩擦,产生热量导致机身温度偏高,但并不是所有温度过高的情况都是正常的。
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.
实验结果表明,导致屋顶风机紧固件失效的原因主要有以下几点:1、运转时,承受过大载荷量。就以轴流风机为例。由于它的运作时叶轮的输出转速快,因而,所要承受的载荷也就较大。一旦它的载荷超出的载荷范围,其内部个零件也需将承担一些载荷量,这就会造成零件紧固件失效。2、骤时开启反转。如果在风机还未完全停止时,突然开启反转,就会使风机的各个部件在受惯性的作用下,分别向不同的方向运行,使其个部件的运行不同步,从而导致风机出现问题。
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.
在发现风机出现紧固件松动现象时应该及时的进行处理,否则的话可能会导导致更大的问题发生。
In case of loose fasteners of the fan, it should be handled in time, otherwise it may lead to greater problems.
