离心风机简要概述和未来发展趋势分析

2018-07-28 19:08:46 常州亿创钣金加工厂 阅读

未来离心风机发展趋势和方向分析如下:

离心风机主要应用于冶金、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,在煤矸石综合利用、新型干法熟料技改、冶金工业的节能及资源综合利用等20多个潜在的市场领域仍将有较大的发展前景。

The development trend and direction of centrifugal fans in the future are analyzed as follows:

Centrifugal fans are mainly used for ventilation and ventilation in various fields of national economy, such as metallurgy, petrochemistry, electricity, urban rail transit, textiles and ships. In addition to the traditional application fields, there will still be great prospects in more than 20 potential market areas, such as the comprehensive utilization of coal gangue, the new dry process clinker, the energy saving of the metallurgical industry and the comprehensive utilization of resources.

随着离心风机制造行业竞争的不断加剧,大型离心风机制造企业间并购整合与资本运作日趋频繁,国内优秀的离心风机制造企业愈来愈重视对行业市场的研究,特别是对产业发展环境和产品购买者的深入研究。正因为如此,一大批国内优秀的离心风机品牌迅速崛起,逐渐成为离心风机制造行业中的翘楚!

With the intensification of competition in the manufacturing industry of centrifugal fans, merger integration and capital operation among large centrifugal fan manufacturing enterprises are becoming more and more frequent. The domestic excellent centrifugal fan manufacturing enterprises pay more attention to the research on the industry market, especially the in-depth study of the industrial development environment and the product purchasers.  Because of this, a large number of domestic excellent centrifugal fan brands have risen rapidly and become the leaders of centrifugal fan manufacturing industry.

离心风机是我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。气体压缩和气体输送机械是把旋转的机械能转换为气体压力能和动能,并将气体输送出去的机械。

Centrifugal blower is China's habit of abbreviation for gas compression and gas conveying machinery. Usually, fans include fans, blowers, and wind turbines.  Gas compression and gas conveying machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy and delivers gas.

离心风机的主要结构部件是叶轮、机壳、进风口、支架、电机、皮带轮、联轴器、消音器、传动件(轴承)等。

The main components of the centrifugal fan are impeller, casing, air inlet, bracket, motor, belt pulley, coupling, muffler, transmission part (bearing) and so on.

无动力通风机是利用自然风力及室内外温度差造成的空气热对流,推动涡轮旋转从而利用离心力和负压效应将室内不新鲜的热空气排出。
The unpowered ventilator is a heat convection caused by the natural wind and the temperature difference between the indoor and outdoor, and promotes the rotation of the turbine to discharge the indoor non fresh hot air by using the centrifugal force and the negative pressure effect.

离心风机关系到系统的输配能耗,是建筑节能非常关键的部分。根据国家空调设备质量监督检验中心多年风机检测表明很多风机在额定工况下都存在问题,因此需要严格按照产品标准要求生产和制造风机。
Centrifugal fan relates to the energy consumption of transmission and distribution system, which is a key part of building energy efficiency. According to the national air conditioning equipment quality supervision and Inspection Center for many years, the fan test shows that many fans have problems in the rated conditions, so it is necessary to produce and manufacture the fans in strict accordance with the requirements of the product standards.

离心风机刚开始工作时轴承部位的振动很小,但是随着运转时间的加长,风机内粉尘会不均匀的附着在叶轮上,逐渐破坏风机的动平衡,使轴承振动逐渐加大,一旦振动达到风机允许的最大值11mm/s时(用振幅值表示的最大允许值如下),风机必须停机修理(清除粉尘堆积,重做动平衡)。因为这时已是非常危险的,用户千万不可强行使用。在风机振动接近危险值时,有测振仪表的会报警。

The vibration of the bearing position is very small when the centrifugal fan has just started working, but with the lengthening of the running time, the dust in the fan will be unevenly attached to the impeller, which gradually destroys the dynamic balance of the fan and increases the vibration of the bearing gradually. Once the vibration reaches the maximum 11mm/s of the fan, the maximum allowable value is expressed by the amplitude value. The fan must be shut down to repair (remove dust accumulation and redo dynamic balancing). Because this is already very dangerous, users must not be forced to use. When the vibration of the fan is close to the dangerous value, there will be an alarm for the vibration meter.
