如何選擇風機彈簧減震器How to choose the spring shock absorber of fan

    風機是依靠輸入的機械能，提高氣體壓力並排送氣體的機械，它是一種從動的流體機械。風機是中國對氣體壓縮和氣體輸送機械的習慣簡稱，通常所說的風機包括通風機，鼓風機，風力發電機。風機廣泛應用於冶金、石化、電力、城市軌道交通、紡織、船舶等國民經濟各領域以及各種場所的通風換氣。除傳統應用領域外，風機廣泛用於工廠、礦井、隧道、冷卻塔、車輛、船舶和建築物的通風、排塵和冷卻，鍋爐和工業爐窯的通風和引風;空氣調節設備和家用電器設備中的冷卻和通風;穀物的烘幹和選送，風洞風源和氣墊船的充氣和推進等。

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.

    風機運行初期軸承的振動很小，但隨著運行時間的增加，風機內的灰塵不會均勻地附著在葉輪上，逐漸破壞風機的動平衡，使軸承的振動逐漸增大。一旦振動達到風機***允許值11 mm/s（振幅表示的***允許值如下）。必須關閉和修理風扇（清除積塵並恢複動態平衡）。因為此時非常危險，用戶不能強行使用。當風機振動接近危險值時，振動測量儀報警。因此，風機減震器的使用勢在必行，如何找到合適的風機減震器進行安裝和使用迫在眉睫。

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.

    如何選擇風機彈簧減震器？風機減震一般采用彈簧減震器、橡膠減震器和氣墊減震器進行隔振。這三個減震器的性能。從成本上看，氣墊減震器的價格***，彈簧減震器次之，橡膠減震器***；從減震性能上看，氣墊減震器***，彈簧減震器次之，橡膠減震器***。在使用壽命方面，彈簧減震器的組合壽命最長。15-20年來，第二個是氣墊式減震器，最差的是橡膠式減震器，根據廠家使用的材料不同，減震器的使用環境也不同。從維護簡單的角度來說，彈簧減震器在使用壽命中幾乎不需要維護。氣墊式減震器充一次氣通常需要一到兩年的時間。使用壽命期間無需維護。一般來說，風機采用彈簧減震器比較合適。

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.
