如何选择风机弹簧减震器How to choose the spring shock absorber of fan

    风机是依靠输入的机械能，提高气体压力并排送气体的机械，它是一种从动的流体机械。风机是中国对气体压缩和气体输送机械的习惯简称，通常所说的风机包括通风机，鼓风机，风力发电机。风机广泛应用于冶金、石化、电力、城市轨道交通、纺织、船舶等国民经济各领域以及各种场所的通风换气。除传统应用领域外，风机广泛用于工厂、矿井、隧道、冷却塔、车辆、船舶和建筑物的通风、排尘和冷却，锅炉和工业炉窑的通风和引风;空气调节设备和家用电器设备中的冷却和通风;谷物的烘干和选送，风洞风源和气垫船的充气和推进等。

Fan is a kind of driven fluid machinery, which depends on the input mechanical energy to improve the gas pREssure and exhaust the gas. Fan is a common abbreviation of gas compression and gas conveying machinery in China. The fan usually includes fan, blower and wind turbine. Fans are widely used in metallurgy, petrochemical, electric power, urban rail transit, textile, shipping and other fields of national economy and ventilation in various plACEs. In addition to the traditional application fields, fans are widely used for ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced air of boilers and industrial furnaces, cooling and ventilation of air conditioning equipment and household electrical equipment, drying and selection of grain, inflation and propulsion of wind tunnel wind source and hovercraft, etc.

    风机运行初期轴承的振动很小，但随着运行时间的增加，风机内的灰尘不会均匀地附着在叶轮上，逐渐破坏风机的动平衡，使轴承的振动逐渐增大。一旦振动达到风机***允许值11 mm/s（振幅表示的***允许值如下）。必须关闭和修理风扇（清除积尘并恢复动态平衡）。因为此时非常危险，用户不能强行使用。当风机振动接近危险值时，振动测量仪报警。因此，风机减震器的使用势在必行，如何找到合适的风机减震器进行安装和使用迫在眉睫。

The vibration of the bearing is very small in the initial stage of fan operation, but with the increase of running time, the dust in the fan will not uniformly adhere to the impeller, which will gradually destroy the dynamic balance of the fan and increase the vibration of the bearing. Once the maximum allowable vibration amplitude of the fan is 11 mm / s. The fan must be shut down and repaired (remove dust and restore dynamic balance). Because it is very dangerous at this time, users can not use it by force. When the fan vibration is close to the dangerous value, the vibration measuring instrument will alarm. Therefore, it is imperative to find the proper use of the damper and how to use it.

    如何选择风机弹簧减震器？风机减震一般采用弹簧减震器、橡胶减震器和气垫减震器进行隔振。这三个减震器的性能。从成本上看，气垫减震器的价格***，弹簧减震器次之，橡胶减震器***；从减震性能上看，气垫减震器***，弹簧减震器次之，橡胶减震器***。在使用寿命方面，弹簧减震器的组合寿命最长。15-20年来，第二个是气垫式减震器，最差的是橡胶式减震器，根据厂家使用的材料不同，减震器的使用环境也不同。从维护简单的角度来说，弹簧减震器在使用寿命中几乎不需要维护。气垫式减震器充一次气通常需要一到两年的时间。使用寿命期间无需维护。一般来说，风机采用弹簧减震器比较合适。

How to choose the fan spring shock absorber? Generally, the vibration isolation of fan is carried out by spring shock absorber, rubber shock absorber and air cushion shock absorber. The performance of these three shock absorbers. In terms of cost, air cushion shock absorber has the highest price, followed by spring shock absorber, and rubber shock absorber is the cheapest; in terms of shock absorption performance, air cushion shock absorber is the best, followed by spring shock absorber and rubber shock absorber is the cheapest. In terms of service life, the combination life of spring shock absorber is the longest. In the past 15-20 years, the second is the air cushion shock absorber, and the worst is the rubber shock absorber. According to the materials used by the manufacturer, the use environment of the shock absorber is also different. From the point of view of simple maintenance, the spring shock absorber hardly needs maintenance in its service life. It usually takes one to two years to charge air cushion shock absorber. No maintenance is required during service life. Generally speaking, it is more appropriate to use spring shock absorber for fans.
